Digital Foundry: Developers tell us that they love the GDDR5, they love the bandwidth but there are questions on latency. How do you cope with that in your set-up? It's not something that developers have much experience with in terms of interfacing with a CPU. Mark Cerny: Latency in GDDR5 isn't particularly higher than the latency in DDR3. Also, GPUs are designed to be extraordinarily latency tolerant so I can't imagine that being much of a factor. DF:GDDR5の帯域は良いけどレイテンシどうすんの? 開発者が今までCPU周りで体験した事無い問題の筈だけど 天才:GDDR5のレイテンシはDDR3と比べてスッゲー遅い訳じゃねぇし!! むしろGPUはレイテンシに寛容な作りだし!! つーかそんな色んな要因なんて俺わかんねーし!! http://www.eurogamer.net/articles/digitalfoundry-face-to-face-with-mark-cerny
