Other notes from the video:
"At the front end of the GPU sits the command processor, which takes the instructions from the CPU and processes them. And here's where things get really interesting - Microsoft's engineer's have effectively made a hardware implementation of DX12 integrated directly into the GPU command processor. Draw call instructions on the CPU that would typically require thousands of instructions are now reduced to just 11. Yes, 11. State changes that are also heavy on CPU are now cut down to just 9. Microsoft tells me that this custom hardware alteration should drop CPU rendering workload by half on titles built on DX12 renderers."
Compute power for the Scorpio GPU is rated at 6.0 TF (compared with 1.31 for the Xbox One, 1.84 for the PS4, and 4.2 for the PS4 Pro).
"So compared to the new Sony console [PS4 Pro], that's an additional 11% Radeon hardware, but a 27% boost to frequency, combined this gives Scorpio a 43% compute advantage."
Scorpio will allow 8 GB of RAM for games, compared with 5 GB of RAM available for games on the Xbox One and PS4 Pro. That leaves 4 GB available for the Scorpio OS, meaning it will reportedly be able to render the dashboard at native 4k.
"[Forza 6] is hitting 4k at 60 frames per second effortlessly. Take a look at the GPU utilization at the top there - 66.19%. Now I personally have seen this demo running on Scorpio hardware and the utilization does vary. I saw it drop as low as 55% with fewer cars on screen, and it can go as high as say 70%. But the point is that this is a straight Xbox One port. The only Scorpio enhancement is the resolution and the inclusion of 4k art assets. This means that, yes, we will see 1080p Xbox One games running at native 4k on Scorpio. But more than that, the fact that the hardware is kind of underutilized means that there's a ton of GPU power left over for making the game look much better."
