Ryzen 3000 series is out

[MikeB]

Are complete 3900x systems available anywhere?
Ideally, with user-configurable options.

Cyber power is one of the better priced options online. That let you configure the system you want. And it is ready for your 3900x configuration.

But please build it yourself. It will be better built and cost less.

I looked at cyber power. They don't offer the sort of RAM I want, and the max they offer is 32 GB.

I was just looking at a stop-gap system. But I will wait for the commercial CPUs or maybe the threadripper, depending on how it tuns out

I would wait for threadripper. My system is ready, all I need is the 3rd gen Threadripper CPU to replace the 2950x. 3rd gen threadripper will be epic....

The commercial stuff is more powerful, but a lot more expensive. The commercial stuff should be ready in September, since that is the end of Q3. If they stick to their schedule, that is.

If the new Threadripper has 64 cores, it will be a barn burner.

The 64 core 3rd generation Threadripper is projected at 150 million nps on the position posted above while using asmfish (SF will be slower of course) - we already know that the 2990wx does 77.6 million/nps with asmfish, so it's a pretty safe projection and it's probably light. Also I understand MSFT had fixed the Windows scheduler issue recently with AMD Threadripper, but I have to see any anything posted regarding the improvement. Without this scheduler fix, Linux was really the only way to go. So for those who prefer MS Windows 10, hopefully the fix works.

What is expensive is letting other people build your computers. The markup is down right criminal. And you get poor quality parts. And poor quality builds for your hard earned money.

Building a PC is as easy as Lego's.
Everything you need to know is online and Free.

Here is a Build from Main Gear. Main Gear is the best online computer builder, and you will get a nice PC. But the markup is insane....

I wonder if the BMI2 slowdown is finally fixed.

I wonder if the BMI2 slowdown is finally fixed.

The pdep / pext instructions are emulated on the Ryzen - why I have no clue,, but what takes one cycle clock on intel, takes several cycle clocks on Ryzen. Over all, the bmi2 exe's are faster on SF vs non- bmi2 compiles ( on intel cpus ) , but we're talking maybe 2% or so, it does not change the value proposition with the AMD Ryzen cpus on a material basis ( to put it in accounting speak ;>))

I would buy my own GPUs (they are about $700 online) and I would get two of them (have to wait until the 23rd for them).
https://www.nvidia.com/en-us/geforce/gr ... 080-super/
So $1400 gets me a lot of GPU compute power.

And a bigger power supply (1000 watts is my minimum).

AnandTech included SPECint2017 benchmarks, which include Deep Sjeng:

The results were...surprisingly bad, i.e. clearly worse than Intel cores. I wonder why.

PEXT/PDEP still take ~18 cycles. You don't want to use those.

I guess they compiled for BMI, but SSE3 builds will be 25% faster.

This is one thread benchmark?

NVidia CUDA is definitely superior programming environment if you're into programming GPUs, especially with the half-float / tensor operations accelerating neural nets.

Radeon VII however is 16GB HBM2 sitting at under $700 card. If you're planning on experimenting with raw GPU power, its good compute power at a cheaper price. You just gotta like... write your own malloc and stuff because the malloc in HIP/ROCm is kind of barebones... https://github.com/ROCm-Developer-Tools ... p_memory.h

But seriously: RAM is an issue on these things if you're hand-coding stuff. Radeon VII has 60 CUs with 256-threads at occupancy 1 (with occupancy 4 being a reasonable goal for most coders). That's 15360 SIMD threads at occupancy 1, 61440 threads at occupancy 4 (with occupancy 10 being the max supported by the hardware).

Occupancy 4 with ~64 tasks per SIMD thread x 1024 bytes of memory per task (~96 bytes for the 12-unit bitmask, ~512 bytes for movelists... you'll get to 1024 bytes per task rather quickly)... and that's... 4GB of RAM. Just on the tasking structures. Not even getting to transposition tables, endgame tablebases or anything else yet either.

Ryzen 3000 itself looks great for typical CPU chess computing purposes. A shame that the BMI2 PEXT / PDEP instructions are still slow on the system, but its not fatal. A ton of threads (the 12c/24t 3900x looks like the best price/performance) fixes a lot of ills.

I think the biggest downside to Ryzen 3000 is that you lose Intel vTune tools. AMD's uProf is workable, but clearly inferior to Intel's vTune profiling suite. The branch-prediction + analysis tools that the Intel chips allow for in high-performance programming situations is very, very, very useful when it comes to understanding what needs to be optimized in your codebase.

With that being said: AMD uProf definitely works. The "instruction based sampling" methodology is strange and obtuse... but it is workable. And uProf is free, so that's also cool.
