LOL Sony PR. More like MisterPlaystationMedia with the amount of deluded losers screaming “MUH GPGPU”, “MUH HSA”, “MUH HUMA” which are all real technologies only on PC and Sony wheeled them out as PR.

Oh and ND’s tech breakdown showed 4.5GB with a floating 1GB pagefile so 5.5GB. You are a liar too

And most PC’s are past PS4 according to Steam Hardware surveys. PC rules all :^)

I read up on it. All on PC with powerful GPU’s that can pool memory themselves. Very little applicable to PS4 since it’s so weak.

Keep yelling about “MUH SEKRIT SAUCE” and “MUH OPTIMIZATIUNS”. The only thing you see in your future is 30FPS, loser.

Actually the steam hardware survey showed that most PC owners are beyond PS4 specs now with Nvidia being the most popular GPU.

And Sony’s PR was all theoretical. None of it actually happened. Mostly because the PS4 is garbage :^)

Nope, Cerny made them out to be secret sauces and now they are only on PC. Stay mad

PS4’s bandwidth is confirmed by an unbiased, multiplatform developer.
As for the AF comment, you should know if you’ve bothered to research that there aren’t any issues with AF, the ICE Team confirms PS4 should be perfectly capable of 16X AF, games that were launched without AF or low AF have been patched, like Dying Light.
The lack of AF is because of the differences in APIs between systems.

CUs can be used however developers like, that’s the point of the extra ACEs, they’re in the system to make sure no GPU resources are wasted, basically they’re an efficiency gainer.

It’s a fact based on the physical hardware differences, Cerny said no such thing, I don’t think he’s ever made a claim for how much of an actual difference there is overall, but 50% more shaders & TMUs is a fact, differences in the scale of fast memory and additional Bus that can bypass GPU cache for direct access aren’t anything but real.

32TBs is what AMD’s own PRT allows, it’s not stated whether that’s per second or whatever and I never said such a thing, so you’re twisting my words there.

I’m not dreaming here kid, I’m just reiterating what the official sources have said.

172GB/s real world bandwidth, never disputed by any of Sony’s own tech docs for PS4 or any developers, confirmed by an unbiased party in Stewart Gilray who is an independent developer that has worked on multiple platforms.

Technically 6GBs are available, confirmed by Naughty Dog’s tech breakdown on Dualshockers and Guerrilla Games Killzone post mortem.

HSA isn’t about power, it’s about efficiency in the hardware design.

Whether it’s pathetic is entirely subjective.

I agree that PC’s with sufficient enough specs will do very nicely, they already do if you have the hardware, but to say such things in a blanket “all PCs destroy everything” kind of way is very misleading.
Not all modern gaming PCs have specs close to PS4 or even XB1 for that matter.

Assuming the rumors of AMD’s Zen APU are true, HSA as a part of a system with multiple GBs of HBM.

LMFAO yes. Bandwidth isn’t constrained in the slightest, not by the use of some multi-threaded code being use on the CPU.
As I said in my last reply to you the latency is comparable to 2133MHz DDR3, which is fine for a PC set-up.

You have a source that says PS4’s bandwidth drops down to 140GB/s when both CPU and GPU use it?

You don’t, because there hasn’t been a single developer or document that confirms the max bandwidth to go that low, when both CPU and GPU access RAM, it really makes no sense given we’re talking about a single die accessing one pool of RAM.
Code should be multi-threaded on the CPU and GPU, which PS4 is designed to handle.

HSA is all about unified memory access for the CPU and GPU, both work together to minimize excess reads and writes.
PS4 is both HSA and HUMA because it’s a completely unified design.

In an APU based PC it would be a similar deal because you have one pool of DDR3, in a PC with an external GPU to the main CPU die you have a separate pool of VRAM that the CPU has to access through not only multiple buses, but also through the GPU’s separate interface.
Some PCs are HSA/hUMA, but only certain ones that comply with HSA/hUMA regulations.

XBox One isn’t HSA/hUMA because the GPU is what directly accesses eSRAM, meaning efficiency is lost if the CPU accesses that pool of RAM.

None of this is garbage kid, it’s all fact, I suggest you read up about AMD’s own technology before making such claims.

Rubbish, GDDR5 Latency at the clock speed of PS4’s set-up is comparable to 2133Mhz DDR3, although AMD Jaguar cores aren’t latency due to their good branch prediction.

Except when Sony’s PR is confirmed to be accurate by AMD’s very own recent tech documents.
This is all fact kid.

As for the “weak sauce”, that’s all relative, it’s not weak compared to the other consoles, which is the point.
Yes it’s weak compared to a decent spec PC, but not compared to what the majority of PC gamers have.

No that’s AMD technology and nothing secret about it, because Sony declared it or rather Mark Cerny did when he was talking about the tech in PS4.
AMD have also detailed all of the stuff I mentioned.

The only secret sauces are the invention in XBox Fanboy’s heads, like split GPU and other made up junk.

LOL!
You mean Windows PC is just like Microsoft Xbox One. Same garbage company different brand.
