But we didn't think we could deliver, with the silicon that's out there, a true 4K gaming six teraflop machine this year. So we decided to wait until we hit the real spec that people were asking for."-Phil Spencer That right there tells me Scorpio uses no Polaris GPU. The Silicon that has yet to enter the market is Vega- which has a higher perf per watt/FinFET scalability. Vega is AMD's architecture aimed to battle the 1070/1080...so that is the perf level to expect....especially taking DX12 into consideration. That extra year means no settling for checkerbox upscale on nearly every title and more native 4K games. When you look at Gears Ultimate Edition/Gears 4 /Forza Apex profile around 4K you end up with a 980Ti GPU...and that's no coincidence. They are going to massage that perf level in their games. |
You need to understand how AMD builds it's GPU's.
AMD will design a GPU in "Blocks" and will modify part or all of a block, then they assemble various amounts of those blocks to form various parts of the GPU.
It is why AMD can take any old Graphics Core Next part and update say... Just the video blocks and add support for stuff like HEVC whilst leaving everything else the same.
Or why Graphics Core Next 4.0 wasn't a complete top-to-bottom update over Graphics Core Next 3.0, only parts that needed modifying/updated were updated.
Vega is likely going to be using the same architectural "Blocks" as Polaris, they aren't going to be radically different from a low-level architectural point of view, there is going to be differences for sure, Vega will use more blocks and have HBM2 memory, but it will still be the same architecture as Polaris.
The question remains... For both Scorpio and Playstation 4 Pro... Is how those blocks are configured, what their clock speeds are and how many there are, and we will not know that untill more official information is released about the GPU configurations.
For example for the Playstation 4 Neo/Pro/4k/Cats to hit it's claimed 4.2 Teraflop Target it could have 2304 shaders @ 900mhz or 2048 shaders @ 1033mhz.
Whilst the Scorpio would likely use 3584 Shaders @ 850mhz or 4096 @ 733mhz. - Or heck hows about 2304 shaders @ 1300mhz? Or 2048 shaders @ 1466mhz?
Although wider hardware with more conservative clocks at 16nm is likely the go.
Can't forget that a few extra CU's would be thrown in for die-harvesting practices to bolster yield too.
