A typical goal is 60hz, which is 17k microseconds. My cursory research says as of 10 years ago a typical write/receive latency for an nvidia card, i7, pcie2.0 is 20 microseconds. That gives you a large budget despite the fact SIMD on chip is measured in cycles not microseconds. Inside the GPU you have a huge amount of space and resources to do highly specialized operations in vast concurrency, I.e., bandwidth for compute is huge and specialized. I don’t see how CPU’s or SOC will solve this without vastly increasing die sizes and heat and power consumption to be close to that of a GPU with all its cooling requirements and heavy power needs. That said I think the “good enough” metric is already there and unless you’re doing hardware ray tracing or extreme details at high resolutions you won’t need or care about a GPU any more. Latency though isn’t the issue. The times involved for human perception are long and not getting shorter.
