Please show me where can you buy a $800 card that can be used to develop for the _compute_ architectures; i.e. the GV100 or the GP100 for that matter. Also, please show me how can you use those $800 cards for serious computing/research

Beats Intel Broadwell and Skylake in many memory-bound codes and surprisingly enough it can compensate with core count and clocks for its meager SIMD units even when running strongly instruction and cache-bound codes like GROMACS. Among t

RX Toaster, they need to pull some magic out of the chip with upcoming drivers, otherwise this won't be the big return everyone expected, I feel. I just hope the MI25 cards will be far cheaper than the $6k Tesla P100's and that th

There goes yet another example of Goodwin's law in action, but I'm not so glad for the arguably rash, overly emotional, and definitely not balanced analogy.

Agreed, see my point below (/item?id=14747906).

Sure, but I was addressing the areas where the Zen arch is clearly not beating Intel. Database, java, etc. are areas where the initial benchmarks indicate that EPYC is quite competitive.

Good point, it looks like they have a decent path forward and hopefully they take good advantage of the new nodes and the available room for refining the uarch. Socket compatibility would be wise, I hope at least the Zen+ I'm hoping th

Thanks for the link. Ugh, per-core licensing is pita. Tell the decision-maker at your work to pay for the cores or switch to some code with more sensible pricing model. Do the alternatives (like Ansys) charge per core as well?

Many if not most HPC/sci. comp applications are memory bound (or actually their implementations are). [ref missing, but google around and you'll find plenty] More and more applications are drifting into the memory-bound regime, es

Why not talk to OEM's? Many have been running benchmarks for some time and surely have an idea about performance -- though one important question is whether that "idea" is biased or not.

It will take some time until that question can be answered. For some it will likely matter a lot, e.g. engineering or HPC applications that rely heavily on dense solvers. however, even for non FP-heavy workloads (like integer-heavy stuff sa

This looks like a solid if not amazing comeback of AMD into the server market. Sure, single threaded performance may not beat Skylake-SP, nor will the LINPACK (and most wide SIMD/FMA-heavy works) performance, but that still leaves most

What scaling are you referring to when talking about "linear"? Did you really get 2x absolute performance going from 128-bit to 256-bit SIMD (regardless of the uarch, e.g. both with SBE and HSW with the former having a relatively

Threadripper & EPYC are a truly epic move to jump into the dense GPU workstation and server market! With a Threadripper you get four x16 GPUs without PLX or three + a couple of SSDs. Time for @nvidia to switch the DGX boxes to @AMD CPUs

...and of course AVX-512 for the lucky ones that can get significant benefit from such a wide SIMD (also considering the very likely significant clock limit for AVX instruction streams).

The poor performance (as well as perf/W for all but 2D graphics). Compare it to an NVIDIA chip of similar die size, TDP, and target form-factor. You'll realize that most Intel chips (other than the top of the line like the P580) a

Looks like they think they're still winning regardless of the price and that simply bumping core count to be the kings and bringing the price back to the Haswell-EP level high (rather than Broadwell-EP crazy) will be enough. What also

That's a blanket-statement and ends up being incorrect/inaccurate. The top Vega card is HBM2, not even in the same ballpark as the 1080. Also, recent Linux patches hint that there will be dual-chip water-cooled Vega boards too whi
