Neo will probably use Polaris but downclocked to be more energy efficient.

Scorpio probably will use next year's Vega but also downclocked to be more energy efficient.

@TheCommentator
They can't just add a few CUs on the older GPUs since that type of chip doesn't exist in that configuration, they probably use Polaris like on the rx 480

Was about to come in and reply the same as Aenea, the rumored Neo spec is a rx480 running at 953Mhz instead of the 1200Mhz that the PC card does which would result in the tflops number being closer to 4 instead of 5.

Where as the scorpio will likely run a slightly underclocked version of Vega, the only point of contention with the vega theory is that it seems that the scorpio will be using some form of gddr5 vram either 8gbps on a 384 bit bus or gddr5x (therefore 10+ gbps) on a 256bit bus, these numbers come from the memory bandwidth listed by microsoft in the conference and the die shot clearly showing more traditional memory chips and not stacked memory, either way Vega is intended to be HBM2 not G5.

Anyways, personally very excited for the RX480 because of its ridiculously low power draw this card could be an absolute beast when overclocked. Hopefully will become "the" card to get when building a decent midrange computer.

I dont think so, the RX480 is a separate dedicated GPU, its unlike how consoles are built.

lol Rx480 and leaked ps4 neo specs are the same. reason lower tflop is because GPU inside console can't be clocked so high therefore less tflops. please do some research b4 making statements as facts. Bottom line Rx 480 in Ps4 neo is clocked lower so expect lower results. Scorpio is not using Rx480 as Overclocked Rx 480 is under 6 tflops but once again Console gpu can't be the same as CPu gpu or OC version too much heat.. Scorpio is using Vega most likely Rx 490 which has not been announced yet .

Wow, the level of ignorance here is astronomical, the Neo almost certainly uses a Polaris 10 GPU core, its just that its clocked at a lower speed (911mhz) instead of its PC card speed of 1266mhz. Which is what makes the Neo 4.2TF vs 5.8TF on the PC. But Sony could easily up the GPU clock and just make sure the Neo has the proper cooling and power supply, heck they can even take out the PSU like the X1 did to keep the heat down. I also dont believe that Scorpio is going to have a Vega core, but instead is just going using the regular Polaris 10 core at is normal speed of 1266mhz, thereby having 5.8TF on the GPU, add the CPUs TFlops and call it 6TF. Also, did nobody notice just how terrible the card was at keeping a steady 60fps at only 1080p? Yet, you people actually think they going to achieve 4K 60fps on AAA games? Prepare to be disappointed.

We don't know the neo specs. Could be a 480 in it.

@ Aenea

PS4's GPU doesn't exist in its configuration either... because it was modified. Sony doubled the Aces from the original spec of the GPU they chose when they built the PS4, so of course they can modify it again. The question is will they modify it again or go with the downclocked 480?

To anybody who claims there's a lot of ignorance around here: You guys need to remind yourselves that you are speculating just like anybody else, therefore everyone here is ignorant because there's no data to prove one theory over the other. Both theories end up coming to approximately the same performance.

Funny how people disagree. I'm a Sony guy but those are just facts.

why dont you give out your full specs your comment sounds a bit fishy i doubt it's true

I remember turning the aliasing down or off on Hair Works to get it running almost perfect
