I wonder how the pretty new 3,000 us dollar Titan V gpu does with these milkyway units 😅

Does it even work for these yet? Anyone even have one? 😅

I heard the milkyway project gpu work units relies on your gpu's double precision processing (so... computing 64 bit numbers?). And I also heard that consumer gaming gpu are typically cut pretty down on the hardware for that instead opting for mostly regular precision 32 bit cuda cores. Probably because the 32 bit cores need less space and power and video games would rather have more cores and more overall numbers that are fine enough for their purpose (my assumption here)

I also heard that the amd radeon 290 series and similar gpu cards have really high double precision compute STILL (compared to most consumer gpu). More than anything nvidia on the regular gtx line. And that you can see computers running those cards at the top of the lists here.

I'm just merely looking at numbers from wikipedia...

rx 200: https://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_series#Desktop_models_2
rx 500: https://en.wikipedia.org/wiki/AMD_Radeon_500_series#Desktop_&_Laptop
rx vega: https://en.wikipedia.org/wiki/AMD_RX_Vega_series#Desktop
gtx 1000: https://en.wikipedia.org/wiki/GeForce_10_series#GeForce_10_(10xx)_series

And here is the new volta titan V. And it's wayyyy more.

So apparently it has plenty of double precision power. Ten times more than any of the stuff above. As apparently the titan line WAS supposed to be a cross between a consumer gaming card and a "professional card" (tho apparently the last few titan entries betrayed that!)

Sooo.. Numbers like that should probably be taken with a grain of salt. But if it could run that much faster I imagine it would run through a couple milkyway units in only a minute! Sounds nutty.

Hmm. If milkyway desires double precision and my nvidia 750ti is pretty limited on that compared to amd cards maybe my card is better served serving other projects. Ehh, the quick gratification getting 200 points in rapid succession is still nice.

Modestly my evga 750ti superclocked at stock gets these done in 665 seconds with an i5-4460 running at stock 3.2 GHz (one core free)

Yeah somewhere I just learned that amd cards have far more double precision compute power and that milkyway uses it. And so I came over here if there's anything about it. I now have more respect for amd hardware.

I have wanted to upgrade to an 8 core Ryzen. Didn't think I'd have reason to consider amd in the gpu slot (other than the driver interface looks pretty nice). Too bad modern amd graphics cards are pretty much all gone. Doesn't seem like that's gonna get much better soon.
