| Captain_Yuri said: My only question now is, what will the performance be like for XSX for games that require more than 10GB of Vram. The only situation on PC that I remember where something similarish happening was with the 970. That GPU had 3.5GB of Vram at 196GB/s and 512MB of Vram at 28GB/s. Now this is clearly not an apples to apples comparison since the 970 has a much more of a drastic difference in Vram memory bandwidth and 10GB is faster than ps5's 16GB. But when pushed to the limit against the 980 which had 4GB of Vram at 224GB/s and games used more than 3.5GB. There were some issues with the 970. https://www.youtube.com/watch?v=UtWL3D9ZL3Q I wonder if there will be any issues with the XSX or if it's not gonna matter at all since the lower memory bandwidth after the initial 10GB isn't nearly as bad. |
My guess is that both systems will perform very similar. Each approach has its pros and cons. Both are limited to 16 GB of system memory, so a lot will depend on the OS and how it manages the system resources. At 4K60 I see no problems at the start of the next generation, but gradually the memory for both systems will be a bottleneck for higher demanding games. And the rest will be determined by the programing and code optimization each developer has for each system. At the time that occurs enhanced systems will appear(2023+) , rendering the initial game systems irrelevant.
------------------------------------------
XBox One SX / Memory: 10 GB @560GB/s (20% faster than ps5) + 6 GB @336 GB/s. (25% slower than ps5)
Overall Performance : 7,616GB (10 x 560 GB/s + 6 x 336 GB/s / 16)
| Pros | Cons |
|
- Higher memory bandwidth - 20% faster processing of resources allocations (textures, maps, etc) - Dedicated memory pool for OS and less demanding tasks. - Better overall performance as a whole. |
- Segmented memory pool - Harder to program (Must choose which pool will allocate resources and tasks) - Limited Fast Memory pool (10/16) - 25% slower memory for OS |
------------------------------------------
PS5 / Memory: 16GB @448GB/s (20% slower than Xbox SX)
Overall Performance : 7,168GB (16 x 448 GB/s)
| Pros | Cons |
|
- Unified memory pool (not segmented) - Easier to program (same bandwidth for everything) - OS memory will run faster (25%) |
- Lower memory bandwidth - 20% Slower Processing of resources allocations (textures, maps, etc) - Slower overall performance |
