Ryzen 3000

HBM2 wasn't used because it's terribly expensive and would have prevented AMD from hitting their price target.

If the 5700XT is performing worse than it should, it's probably due to the new arch. The same has happened with NV in the past. Requires the projects to update their code. It should perform only about 12% worse than the VII at FP32 but capable of only 20% of the FP64 the VII can do.

Is FP64 Milkyway? Any other projects use it? NV has terrible FP64 unless paying out the wazoo for a professional card...

Asteroids, Primegrid GFN-21 and 22, Einstein and of course MW

Thanks. Be interesting to see when this all gets back in stock.

The new Epyc's came out today if anyone has one of those systems. 64c/128t per CPU. 8 channel memory. 128 PCIe 4.0 lanes and 4TB of RAM. Same socket.

And it's about $3k cheaper than Intel's Xeon Platinum 8180

If someone can handle a $7k pricetag.... ($14k for a dual setup which Supermicro offers)

Be one hell of a cruncher though with more than enough lanes for quite a few GPU's also.....
120+ lanes? you can do 4 relatively high end GPU's on 40 lanes..... (with judicious setup), anyone ready for a 10 GPU setup at 8x natively? (no one builds such a critter unfortunately and it would be pricey)

This chip makes a Tyan Supercomputer look like an adding machine.....

Yeah of course there are lower priced options. 160 gen 4 lanes with 2 chips and supports 8TB RAM like that. I would've posted links to benchmarks from Anandtech, Phoronix and Servethehome but it beats Intel so significantly that I don't want to be responsible for giving someone the itch to splurge on this setup

The AMD using normal AVX2, just as fast as Intel using AVX-512. Impressive!

I asked VietOZ to downclock his new 3900X to the same as his TR 2990WX and he ran some AVX Asteroids. The 3900X was 40% faster per thread than the 2990WX. Off hand I'd say they fixed the AVX/FMA problem
