"So a GPU's SIMD unit is inevitably going to be bigger, more parallel, and more efficient than a CPU's SIMD unit." Except if memory latency transfer is a bottle

"So a GPU's SIMD unit is inevitably going to be bigger, more parallel, and more efficient than a CPU's SIMD unit."
Except if memory latency transfer is a bottleneck.
I've seen many examples of SIMD beating GPU e.g pathfinder v3 text renderer
- slaymaker1907 7y agoWhile memory latency transfer between the CPU and GPU is an issue, GPUs have absolutely incredible throughput when moving things from one place on the GPU somewhere else on the GPU. This is why researchers are looking at GPUs for running graph algorithms.
