| Adinnieken said: • 18 CU's vs. 12 CU's =/= 50% more performance. Multi-core processors have inherent inefficiency with more CU's, so it's simply incorrect to say 50% more GPU. • Adding to that, each of our CU's is running 6% faster. It's not simply a 6% clock speed increase overall. • We have more memory bandwidth. 176gb/sec is peak on paper for GDDR5. Our peak on paper is 272gb/sec. (68gb/sec DDR3 + 204gb/sec on ESRAM). ESRAM can do read/write cycles simultaneously so I see this number mis-quoted. • We have at least 10% more CPU. Not only a faster processor, but a better audio chip also offloading CPU cycles. • We understand GPGPU and its importance very well. Microsoft invented Direct Compute, and have been using GPGPU in a shipping product since 2010 - it's called Kinect. • Speaking of GPGPU - we have 3X the coherent bandwidth for GPGPU at 30gb/sec which significantly improves our ability for the CPU to efficiently read data generated by the GPU. |
- GPUs scale diffrently than CPUs and the workloads are massively parallel, thats just wrong.
- ?? This will not help offset the advantage in cores the PS4 has at all.
- The memory Setup of the Xbone is not ideal for graphics.
- 10% more ressources of CPU well Kinect has to listen and has to have ressources reserved at any time the PS4 doesnt have that Handicap. Better Audiochip ? Thats just a guess. AFAIR Sony mentioned some Co-Processors too. But hasnt further specified what exactly is inside.
-?? How is that relevant ?
- What good can it do if you dont have enough GPU Cores to spare for General Processing anyway ?
The problem is due to the Esram MS had to sacrifice many transistors that could have been used for processing instead but they decided to use them as a way to make DDR3 usable for next gen.
