In reply to Nintengods. What's the video?

In reply to Mr Xrat.

Truth is the 16bit x 2 is a first to take place and at same time when used this allows devs to free up more half-floats in less space.

Like I stated before it’s not all about TeraFlops as when using both 32bit and 16bit x 2 within a single 32bit it should allow for more TeraFlops as we knew it before ( when compared to something like on PS4 ).

A half-float would take the same internal space as a full 32-bit float ( on PS4 ), but now you can use two 16bit half-floats in that same space within a register while using fewer vector registers ( PS4-Pro ). So thanks to the above devs will be extracting more utilisation from allowing more wavefronts to run at the same time.

Pretty clever way of making best use of what’s available. I expect Xgimps to be very mad about this.

In reply to Gamez Rule. Mark Cerny becoming MisterXMedia and claiming there's hidden secret sauce because the prolapse is a garbage console that is already being price slashed on Amazon and only 10% of the games are actually 4K. kek. Sonycucks in complete delusional mode after Nintendo completely savaged them with a three minute video and a product people actually want.

In reply to Gamez Rule. ill be getting the Vega 10 beast. Wonder if the gaming version will still have 16GB HBM2... have to wait and see

In reply to Psionicinversion. Good news knowing a little more on what PS4-Pro has. I'm gonna get the PP anyway ☺

In reply to Gamez Rule.

the double half precision sounds like its come from vega same as checkboard rendering seeing as it says it uses future AMD tech which can only mean Vega GPUs. I think AMD could of primarily developed checkerboard for VR and/or to help with GPUs pushing those higher resolutions without resorting to pure power. Checkerboard rendering is handled completely by the hardware so no api additions are needed but apparently devs can have some control but its primarily all hardware based.

Cant remember when delta colour compression came in with amd, think it was hawaii (290/x), or maybe Fury. Either way it will of gotten better with polaris and better with Vega. Just depends which version of it is in ps4 pro. If its SIMD structure is the same as polaris then it will probably have the polaris version seeing as vega is completely revamped. Have a little read of vega and cant wait for the deep dive

i think DCC gives about 40% increased bandwidth but not total bandwidth only on a certain aspect but i cant remember what it is, Look on youtibe or google nvidias demo of DCC and youll see what it does and how it works

“One of the features appearing for the first time is the handling of 16-bit variables – it’s possible to perform two 16-bit operations at a time instead of one 32-bit operation,” Mark Cerny said. “In other words, at full floats, we have 4.2 teraflops. With half-floats, it’s now double that, which is to say, 8.4 teraflops in 16-bit computation. This has the potential to radically increase performance.” * Sounding great so far*

Also PS4-Pro has an additional 1GB DDR3 RAM to free up the GDDR5 RAM allowing more RAM for gaming and application functions. ( 9 GB of RAM ) is a bonus, and with higher bandwidth too *looking good*

Just have a read here☺
