[QUOTE=Xyzzy;592420]NVIDIA RTX A4000[/QUOTE]Interesting. Looks like a good TF engine, but at 1/32 SP/DP, PRP, LL, P-1 not so much. Slower memory rate and much slower DP than Radeon VII. Single slot and reasonable wattage. Listed at B&H Photo at $1400. [URL]https://www.bhphotovideo.com/c/product/1644218-REG/pny_technologies_vcnrtxa4000_pb_nvidia_rtx_a4000_graphics.html[/URL]

No ECC memory either, from what we can tell.

I've been eyeing the RTX A6000.

Are these cards RTX A4000 / A6000 professional cards somewhere between consumer cards Geforce RTX 30xx and professional Tesla V100/A100 ?

The RTX A6000 is the top-end professional workstation equivalent to the RTX 3090. The RTX A6000 is slightly slower than the RTX 3090 but has double the memory, 48GB vs the RTX 3090's 24GB.

The A100 is a server GPU accelerator. It has no video outputs. It has fewer CUDA cores than the RTX 3090 and RTX A6000, but supports much faster HBM2 memory, has a 1/2 DP/SP ratio, and generally outperforms the other cards.

The nVidia workstation cards, RTX A[456]000 support ECC.

A review of GPU overclocking software

Missing from the software roundup is any mention of control of power or clocking from the command line, such as is possible with nvidia-smi, for system startup or logon scripting. Still looking for the AMD command line equivalent functionality on Windows.

[QUOTE=frmky;592492]The nVidia workstation cards, RTX A[456]000 support ECC.[/QUOTE]The RTX 4000 didn't so we assumed the newer card was the same.

Here is something we learned recently: [url]https://www.mersenneforum.org/showpost.php?p=592513&postcount=87[/url]
