PS4/Xbox One Clock Speed Isn’t A Reliable Way To Compare Performance, DX12 Can Boost Cloth Simulation

“The number of processor cores has increased as well, and so has the memory bandwidth,” explains Cloakworks’ Joe van den Heuvel.

The new consoles, PS4 and Xbox One, for the most part have a powerful GPUs backed up by a solid amount of memory but the clock speed of their respective CPU are no where closer to what we have in modern gaming PC CPUs. The Xbox One is clocked at 1.75Ghz whereas the PlayStation 4 is rumored to be a clocking at 1.6Ghz with the capability to be over clocked at 2.75Ghz. So how do these numbers matter in cloth simulation technology?

GamingBolt recently got in touch with Joe van den Heuvel from Cloakworks, a company that specializes in cloth simulation in video games. “Clock speed isn’t always a reliable way to compare the relative performance of two different processors,” Joe tells us. “The key difference with the processors of the latest generation is that they are a lot wider. The number of floating point operations that a can be done with a single SIMD instruction has doubled since the last generation. The number of processor cores has increased as well, and so has the memory bandwidth. This all adds up to a massive opportunity to do work in parallel, and Shroud takes full advantage of that; it can go very wide to enable outstanding throughput performance,” he further explains.

Cloakworks is a technology that is mostly dependent on CPU so we asked Joe about the benefits DirectX12 can bring to the simulation, especially given that the CPU Overhead is expected to reduce by 50% with DX 12.

“DX12 is very exciting for us! As a CPU-based technology, having more CPU processing power available is always a plus. But more than that, pushing the results of the cloth simulation to the GPU to be rendered every frame has some overhead associated with it. If DX12 can help reduce this overhead it could make using Shroud even more attractive to developers,” he explained.

    Hopefully this generation of consoles really pushes devs hard into the multi core arena. We have had games that use multi core architecture for a while but they never have used it to its fullest. Its understandable though. Using multiple discreet cores as if it were a single incredibly powerful one is beyond difficult.

    It’s the direction that not only gaming but general computing has been going for years but a lot of engine tech still relies on a single really fast core.

  • andy

    Clock speeds in black and white are wrong. Yay for bogus unproven theories on an unknown technology. First it doubles the power of Xbox One, next it won’t do anything at all.

    • Khurram Liaqat

      This.
      Solely relying upon clock speed and core counts are not reliable methods of comparing performance.
      Hardware is complex. You can’t boil it down to a frequency.

    • Guest

      Pretty much.

  • Dirkster_Dude

    If the developers have better tools they will have an easier time to build better games. DX12 can certainly up the ante in that respect. Even for PS4 games ported to a Windows platform. It would then almost certainly be using DX12 or OpenGL for the game.

    • GHz

      By the time XB1 gets 100% implementation of DX12, PS4 will be using mantle to maximize the use of its hardware. That way, porting games will be easier. Mantle is the gateway or a stepping stone to DX12. Mantle gets close to the metal, while DX12 does the same plus offer access to new rendering processes if your GPU/APU supports them.

    • Khurram Liaqat

      Source?
      While Mantle is an open API (AMD is pushing it to linux), I think its purpose was more to do with getting console levels of “closer to metal” on the PC. Similar story with DX12 reducing CPU overhead
      .
      Both of these technologies are really more to do with PC I believe.

    • GHz

      For the fact that the consoles are packed with AMD GPU both can use mantle if devs decide to. My mistake on the ps4 mantle thing. PS4 own APi is sufficient.

      In regards to DX12 and XB1, that’s common knowledge now.

    • Khurram Liaqat

      Ah, thanks for confirming it was speculation.

    • Matt

      Mantle and DX12 mainly benefit the PC more than consoles. DX12 is being used to market the Xbox 1 right now but it’s main and soul purpose is to get PC gamers to upgrade to Windows 9 when it comes out (I dare someone to try to deny that). From what I understand the Xbox 1 is using a modified version of DX11 which utilizes only 1 core for a majority of the render pipeline (at least on PC) and DX12 will allow that that workload to be spread out across the entire CPU AKA “scaling”. It basically does what Mantle does but universally instead of relying on proprietary software. Don’t get to hyped up on Mantle btw… with the announcement of DX12 it will get overshadowed just like every other API that used the same strategy though it will get some love from EA for the next couple of years or so before it’s forgotten for the next new thing for GPU’s.

    • Khurram Liaqat

      Pretty much. I haven’t looked into much of the technical side of things, but maybe I should. More excited for free sync / gsync ATM, now that DX12 is set to shake things uo for once.

    • JerkDaNERD7

      Your understating in how significant a benefit is for Dx12 reducing the API overhead by 50%. But at the end of it, it has no benefit til’ a developer uses it specifically. Also most of all is multi-threading, which is something fairly new to consoles.

      Only developers I know for sure will use are their first party studios. But most of all will see a huge benefit for PC.

    • Guest

      You’re still spewing this nonsense like its fact, when this is only partially true for the PC, after all 3dmark is only a synthetic benchmark, and everyone in PCs know that you cant go by synthetic benchmark. Dumb consoletard!

      I’m a PC Gamer…

      And what I stated is NOT nonsense. It’s your ignorance…

    • AndrewLB

      What are you talking about? DX11 on PC uses as many processor cores as are available in most modern games.

      Here is the CPU usage while playing Watch Dogs.

    • Matt

      Both consoles are weaksauce you tard.

    • Guest

      PS4 has great price/performance value for $400. They aren’t going to sell $900 consoles for $600 anymore like the PS3. That’s business suicide.

      Businesses exist to make money, that’s why PS4 has the specs and price it does. Your expectations for a $400 box are what’s ridiculous. Wait for Naughty Dog to show what PS4 is capable of.

    • Matt

      I’ve personally never been interested in the linear story driven Naughty Dog games… They take themselves to seriously and usually tag on a copycat MP with minor differences from their other games. Watch people attack my opinion but seriously… I’ve never been able to enjoy more than one playback of Uncharted and watching someone play TLOU was absolutely boring.

    • Guest

      PS4 uses its own low level APIs.

    • GHz

      Youre right! Devs are satisfied with the low level access provided by the ps4 API.

    • JerkDaNERD7

      Sony developers don’t really need Mantle if they have their own specifically designed for PS4. Dx12 will be more successful than Mantle, It has a whole design feature far passed Mantle…simply because it’s DX, lol!

  • Matt

    Good reason for children to get into arguments over theoretical clock speeds. The 150Mhz doesn’t amount to much unless it’s an overclock on the GPU… I doubt the PS4 could handle a 1+Ghz overclock without reaching a problem with the TDP limit considering how compact it is. Mind you it is possible if AMD implemented an extreme Turbo Core in the PS4’s APU but the Dev’s could do more with 8 independent cores than 4 beefed up ones. One thing you need to learn from marketing though is that if they’re not gloating about it in any of their talking points then there is nothing there that will “WOW!” the consumer so they twist it to sound as good as they can. 8 CORES! ESRAM! GDDR5! 8 GIGS!

  • Guest

    Ok, seriously, you need to stop spouting all these fallacies and assumptions here, Gamingbolt. We do not know for a fact that DX12 is going to give X1 a 50% boost in CPU performance, we do know from a synthetic benchmark on the PC that it may do that for the PC, but not the X1. And 2.) the PS4’s CPU cannot be overclocked to 2.75GHz, another fallacy. You need to stop spreading this misinformation for all these fanboy children (or immature adults) to be fighting over. What you need to do ask get these devs and companies to start giving us the real numbers and stop this PR/marketing crap.

    • JerkDaNERD7

      That’s the problem, it’s NOT a 50% boost in CPU performance. It’s the reduction in CPU overhead that alleviates the GPU for further drawcalls. You and your fanboys sentiments are no different from the Xbox fanboys who claim this as a boost.

      The confusion here is your ignorance more so than actually knowing what your talking about, you and the likes of superkarma.

    • Guest

      Well said! 😀

    • Guest

      Well Said? Wow, you’re not to bright are you?

    • Guest

      Are you stupid or something? Cuz you sound real f-ing stupid. How am I a fanboy, when you’re the dumb fanboy getting all offended over the truth. You do not know that the 50% boost/reduction is for the X1, you just obviously wish is it. You’re the one with fanboy sentiments. And the fact that you act like only people who are into Sony are fanboys, but not the MS guys, shows what a MS fanboy you really are! Btw, what an appropriate avatar you have, cuz that’s all you are, is a rat, a rodent, a vermin. Keep believing this nonsense, while the PS4 keeps on having the superior versions. And I could care less about the PS4 cuz its just a weak, pathetic toy for you children and the X1 is even weaker. Yet you clowns stick up for it. Pathetic!

    • JerkDaNERD7

      I’m sure I wasn’t offended, if anything you come off truly offended by me just for stating facts. Once again it’s NOT a boost in performance, obviously the numbers doesn’t increase hence no boost.

      Also, if you weren’t as emotional and conveyed correctly what I stated, you wouldn’t miss my point completely. I simply stated that you and Xbox fanboys share that same sentiment of ignorance when spewing BS in the comment section. Just as the same who claim 50% boost, you along with Sony fanboys try to refute it otherwise when the argument is simple…IT’S NOT A BOOST IN THE FIRST PLACE! Pathetic?! Yes you are…

      The benefit in the API overhead reduction is a capability, NOT a boost in power as would a overclock would be which has already been done to the XOne last year before it’s launch.

    • Guest

      Just admit it, you think Xbox One is actually more powerful than PS4 as soon as they turn on the special sauce DX12 ESRAM engines or whatever misterxgarbage is in your paranoid schizophrenia suffering head.

    • Khurram Liaqat

      There’s not really any magical “real numbers” to compare performance with. Computers just aren’t that simple anymore.

    • GHz

      You said “We do not know for a fact that DX12 is going to give X1 a 50% boost in CPU performance,”

      Rashid did not say that. he said, “CPU Overhead is expected to reduce by 50% with DX 12”

      2 different things.

      You said “the PS4’s CPU cannot be overclocked to 2.75GHz, another fallacy”

      Yeah Rashid is rolling with what sony claims and thats straight from FCC documents noting a “max clock frequency” listing of 2.75GHz.

      Will it be put into practice is a different story. Who knows. Rashid said nothing wrong!

    • Matt

      That’s the GDDR clock

    • GHz

      But…..

      http://vr-zone.com/articles/sony-reveals-ps4s-cpu-clock-frequency-runs-8-x-1-6-ghz-43-times-powerful-ps2/73617.html?no_redirect=true

      “In a recent Google+ post, Sony’s UK branch delivered an interesting bit of info on the PlayStation 4′s internal specs. According to the post, the PS4′s AMD-designed Jaguar core has a clock frequency of 8 x 1.6 GHz and is 43 times more powerful than the yesteryear PS2 console.

      Up until now Sony hasn’t revealed exact figures on the console’s Jaguar core speeds, however it appears that the console can fluctuate up to 2 GHz–utilizing a good portion of the maximum 2.75 GHz clock speed.”

    • Matt

      2.75GHz is the without a doubt the operating clock of the GDDR… 2.75 x 2 = 5.5GHz.

    • GHz

      Not saying no. Just that they are also reports out there that speaks specifically about the CPU having that maximum speed of 2.7GHz. Could they all be wrong? Sure! But thats what they are saying also.

    • Matt

      Notice how it says Max Clock “In the system”… a lot of the articles are just based off of that FCC picture… The Rango guy below obviously gets his information from sites like that. I hate when people answer their own questions but still write them in an insulting way. It’s not worth responding to him… but yeah. 2.75GHz is the max clock in the system which fits right in line with how GDDR clocks are broken down. All ram clocks are cut in half if it’s DDR (Dual Data Rate)… Nothing is actually clocked at 5.5GHz.

    • Guest

  • JerkDaNERD7

    It’s about the increase in GPU drawcalls and unlocking further cores, which is huge for console.

  • HisDivineOrder

    Microsoft themselves via Spencer recently admitted that DX12 isn’t going to mean much for Xbox One. DX12 huge improvements are coming mostly to PC where low level access is new. Xbox One already has that and so most of the improvements DX12 is bringing won’t apply to it.

    • Vious

      what he said can be taken many different ways.

    • GHz

      What he said was straight up. No hidden message there. It’s just that pple took it out of context as usual. They discussed that @ GDC already. Phil gave an uncomplicated answer based on what we all know as geeks in regards to XB1 and the message given @ this years GDC.

    • justerthought

      The context you should take it is within the knowledge of how PC’s and consoles work. Anything that optimises something that has already been optimised on consoles is going to have little effect on consoles. Why is that so hard for you to understand. You are just arguing over semantics instead of how it affects the reality.

    • GHz

      “It’s not going to be a massive change because as we all know, XB1 API is already low level and incorporates some DX12 already”

      That’s what I said. But you’re trying your best to convince yourself that I believe different. Why?

    • Michael Norris

      You do know the Xbone API already uses low level coding.

    • GHz

      “DX12 isn’t going to mean much for Xbox One.” He didn’t say that nor implied that. Thats your wording, because the impression engadget gave you when they said things like “Xbox head Phil Spencer appeared to dump cold water on the idea that DX12 would make a major difference for the console”.

      That is taking someone’s words out of content to cause confusion.

      Phils exact words are, ““It will help developers on XBOX One. It’s not going to be a massive change but will unlock more capability for devs.”

      It’s not going to be a massive change because as we all know, XB1 API is already low level and incorporates some DX12 already, just like you said. What is important is that he also said, ” unlock more capability for devs.” They also discussed that @ GDC. Unlocking features as they stated, that only yet to be released cards from NVIdia and AMD will have access to.

      “Tamasi explained that DirectX 12 will introduce a set of new features in addition to the lower-level abstraction, and those features will require new hardware. In his words, Microsoft “only teased” at some of those additions this week, and a “whole bunch more” are coming.”

      Microsoft won’t discuss these features until they are ready.

      http://wccftech.com/microsoft-teased-directx-12-features-reserved-generation-gpus-unveil/

      Everyone seemed to have forgotten that for some reason.

      June 2 2014. AMD and Microsoft presentation slide

    • justerthought

      Yes that’s what Phil Spencer said, so intelligent people can read that the improvement to XB1 will be small because the low level CPU optimisation is already in place. PC’s on the other hand get a huge leap in CPU performance. That is exactly what the other comment said that seemed to rub you up because you don’t want to admit it.

      Software upgrades can only get you so far then after that you hit the brick wall of the lame hardware inside the XB1, which was designed to perform best at multimedia not games. Eventually you will realise that and admit it, instead of constantly waiting for the magic sauce that will cure everything. There is no magic sauce just lame hardware.

    • GHz

      Dont really care how you want to take it, or how you perceive me taking what Phil said. The 1st party games speak volumes, and especially what the developer community have to say as they get better at working on the XB1. It takes some amazing” lame hardware” to do games on horrible SDK’s that the PS4 found so hard to match. Cant wait to see what it can do when the tools get better.

      What have working with the xb1 “lame hardware” has produced? Two driving games, each distinctly offering different experiences. The newest, FH2, employing techniques that DC devs found difficult to implement so much so that they had to delay their game. XB1 “lame hardware” will help beat driveclubs devs in employing dynamic FX in FH2, that we will have to wait for via patch on our PS4. XB1 “lame hardware” had produces 2 killer driving games in the same span time it took sony to do 0ne on the ps4. Maybe there is more to XB1’s “lame hardware” which you hope is not there.

      Point is, the games say different.

      Cant wait to play superior looking games like Quantum Break, Forza H2, Crackdown, Sunset Overdrive on my “lame” XB1. 😀

    • Guest

      “the PS4 found so hard to match” LOL the PS4’s hardware is more powerful. Any game running on Xbox One can be run with better framerate/resolution/visual effects on PS4.

      “DC devs found difficult to implement so much so that they had to delay their game” Completely wrong, delusional, and evil LIES.

      “XB1 “lame hardware” had produces 2 killer driving games in the same span time it took sony to do 0ne on the ps4″ This has ABSOLUTELY NOTHING to do with hardware power. Completely wrong, delusional, and evil LIES.

      ” Maybe there is more to XB1’s “lame hardware” which you hope is not there.” The misterxcultists STILL think Xbox is more powerful than PS4. Get mental help for your paranoid schizophrenia.

    • Guest

      Yet another misterxmedia cultist believing the opposite of reality. You realize sane and knowledgeable people either shake their heads or laugh at you, right?

      “He spouts this crazy utter nonsense backed up with out-of-context powerpoint slides with MS paint scribbled all over it and his followers eat it up like he’s this spellbinding prophet. I know I should just laugh it off but these people are brainwashed – that dude is running a cult.” LOL

  • Lamanuwa

    Makes lots of sense, nobody in the industry wants to say it but IMO PS4 beats the XBO APU hands down in so many ways you need a full hour to explain what’s going on and why that happened.
    DX12 will boost performance for the XBO but the industry is moving away from it rapidly into Mantle and OpenGL and in the mean time you can see from the Uncharted 4 footage, the Sony ICE team is not sitting on their hands. After all they only have one hardware unit to focus on.

  • Guest

    LOL no.

    Stating facts and reality doesn’t equal “being nervous and afraid”.

    Factual PS4 Hardware Advantages: +6 CUs, +540 GFlops (40% greater) or more, +16 ROPs, +6 ACEs/CQs, better GPGPU support (volatile bit and onion+ gpu cache bypass bus), better performing CPU, faster unified memory, and less OS overhead.

    If they’re both running at the same resolution the Xbox version will have lower framerate and/or visual effects, or the PS4 hardware isn’t being pushed. Any game running on Xbox One can be run with better framerate/resolution/visual effects on PS4.
