The software being run has to actually be able to take advantage of that potential performance. If more credit per hour means more numbers crunched, then how come the GTX580s crunch more numbers than a 4x faster card (in GFLOPS aspect)?Ī cards GFLOPs rating is a very much a theoretical number. (Actual power usage varies but is often ~70% of TDP while running classic workunits: 93,865 CPU time: 863,447 hoursĪ. The RX 580 lists for ~$200USDĭouble Precision performance: GeForce GPUs are limited to 1/32 SP FLOPS. Some of the notable differences between the two I can think of right now are:Ĭost: The GTX 1070 lists for~$400USD. With the GTX 1070 rated at 5783/6462 GFLOPS Base/Boost and the RX 580 at 5792/6175 GFLOPS Base/Boost. Since those are both current models that came out this year and are rated for about 6 TFLOPS in Single Precision. Really you would want to compare a GeForce GTX 1070 to the Radeon RX 580. Given the GTX 580 was released in 2010 and the RX 580 in 2017. I'm not sure why you would compare a Nvidia GTX 580 to a Radeon RX 580. It might be not worth it to optimize further for just a few AMD cards, which would be really sad for me, since my RX is crunching for SETI most of the time. Maybe, just maybe, if some skilled individual(s) spend some time optimizing the code for AMD cards more, we'll get some of that needed power for "free"? Bear in mind however, that I don't really know how many of the AMD owners are contributing to with all the mining craze currently raging. Maybe the workload is just too non-typical and AMD cards have no shortcuts crunching it? Maybe I'm simply misinterpreting the chart?Īnyhow, yesterday I got an email from about how much more processing power is needed for the new telescopes and projects. CUDA vs OpenCL, or other cruncher optimizations. This means that the key is in the "other factors", e.g. No way nvidia's GTX580 crunches more numbers than a RX 580, all other factors aside. That is 5 times (!) more raw power.ĭo you really believe the alt coin miners would go for 100s of AMD cards if they had a way to make GTX580 profitable? RX 580 on the other side has ~6.2 GFLOPS. Professional offerings are almost neck-and-neck (drivers and SW support not taken into account).Ī GTX580 (stock clocks) has ~1.6 GFLOPS of compute power. Fanboy-ism and trolling aside, we all know historically AMD cards have (almost) always had better raw computational power in the consumer market.
