| megafenix said: well, not sure how much access the cpu has for the edram, but doubt its going to be more than 4MB cause intensive work calculations dont rquire that much size, besides edram is more important for graphics, the importance of the cpu access to the edram is more about having a pool where it can communicate and transfer data to the gpu, kind of like tjhe huma technology that amd announced some time ago. |
But the CPU still has access if need be, which should help it cope with CPU intensive segments like, say, a multi-vehicle crash.
Plus, dev logs from June 2013 state that they had the game running on just one of Wii U's CPU cores, so it seems unlikely that the CPU will be much of a problem if they still have another two cores to draw on. http://www.cinemablend.com/games/Project-CARS-Wii-U-Features-Particle-Shadows-Multi-Threaded-Shadowing-59659.html
But yes, more of the eDRAM will likely be used for graphics.
Shin'en stated on twitter that a double-buffered 1080p frame took up 16MB of eDRAM, so yeah, a double buffered 720p frame should be about 7MB. That leaves 25MB of eDRAM left over for other purposes.
