4のCPUメモリバス幅は20GB/sしかない GPU has full access to the 176GB/s bandwidth of the PS4's GDDR5 via Garlic, while the Onion gets by with a significantly lower amount, somewhere in the 20GB/s region UbisoftはE3で"The Crew"のPC版を30fpsで動かしていたが、PS4に移植すると10fps程度でしか動かなかった At the Ubisoft E3 event, the PC version of The Crew was running at 30 frames per second, but the first working compilation of the PS4 codebase wasn't quite so hot, operating at around 10fps. http://www.eurogamer.net/articles/digitalfoundry-how-the-crew-was-ported-to-playstation-4

>>69 貼るなら説明付きで貼れ http://www.vgleaks.com/durango-memory-system-example/ This example assumes what’s expected to be a typical CPU load and a maximum GPU load: Three display planes are enabled at 1080p resolution. Display write-back is writing a 1080p image at 60 FPS. Move engines are idle. Read bandwidth of the command buffer and index buffer is 4 GB/s. Regular GPU rendering consumes the rest of the available bandwidth.
