Wonder it this could help to alleviate the momentary shortage of GPUs on the market.
- ZiiS 3y ago10 year old entry level GPUs have 100 750Mhz cores
- monocasa 3y ago'Cores' are really overstated in GPUs. CUDA cores are really SIMD lanes and if you counted it the same way as a CPU does, you'd get somewhere in the dozens of cores range even for modern GPUs.
- xigency 3y agoThat seems backwards to me. Sure, a GPU core is less general, but in terms of concurrent execution, memory bandwidth, and FLOPS I would expect hundreds to thousands of cores for all new GPU offerings. Apple’s double-digit GPU core counts for instance sound extremely understated.
- monocasa 3y agoIt's not. The best comparison is the SM count for Nvidia hardware, or the wavefront count for AMD hardware. So a 4070 has 46 cores as you'd count them on a CPU.
- imtringued 3y agoIf you have a truck that can carry 64 boxes, then according to Nvidia marketing each box would be considered its own core even though the boxes all go the same way. Meanwhile if you had 64 passengers cars, then each of them would be able to drive a different route at the same time and if you counted the seats you would actually end up with 320 "Nvidia cores".
- codedokode 3y agoA proper method is counting ALUs instead of vague "cores".
- deaddodo 3y agoIf you want to count "cores" in a GPU, the best equivalency is streaming multiprocessors. While it's true that they're in the dozens, strictly speaking, we've got GPUs with well over 100 now (the RTX 4090, for instance) and 64+ is a pretty common configuration.
- kristianp 3y agoFrom the abstract: "The eGPU architecture is a streaming multiprocessor (SM) machine with 512 threads. Each SM contains 16 scalar processors (SP)."

- monocasa 3y agoIf it's on an FPGA then it doesn't really compete with GPUs you can buy from just about any perspective other than openness.
- latchkey 3y agoI don't think this will be momentary. Reality is that there have been shortages of GPUs for a long time now and demand isn't going down. People are signing 3 year contracts with lambda now.
