06:20:48 <sech1> "TSMC's 5nm node, featuring dual 128b Vector Units, 2MB of L2 cache per core, 3 GHz clock speed, eight-channel DDR5 memory controller, 128 PCIe Gen 5 lanes, and a 200-350W TDP" should be perfect for RandomX
09:39:44 <hyc> 2MB L2 per core, nice
09:39:48 <hyc> they finally clued in
09:43:22 <hyc> 192 cores 350W TDP, is that a bit high TDP?
09:44:57 <hyc> 5nm process, this chip should beat most other chips for efficiency
09:49:06 <sech1> 350W is okay for 192 cores
09:49:14 <sech1> less than 2W per core
09:49:58 <sech1> IIRC they have 2 MB L2 per core, but shared L3 is small
09:51:05 <hyc> would be fun to run some benchmarks on it anyway\
09:53:21 <elucidator> 3 GHz sounds pretty good, what were the previous iterations like ? near 2GHz or close to 3 ? 
09:55:09 <sech1> https://amperecomputing.com/briefs/ampereone-family-product-brief
09:55:57 <sech1> ARMv8.6 instruction set, it most likely has AES too
09:57:03 <sech1> 8-channel memory means a single CPU can go up to 100 kh/s
09:57:20 <sech1> not bad for 350W
09:57:45 <hyc> 8 channel DDR5, all the latest goodies
09:58:12 <sech1> that's north of 250 h/J efficiency
09:58:25 <sech1> it will be worse at the wall, but definitely better than what X5 can do
09:59:06 <elucidator> and probably it won't seppuku itself after 5 days
09:59:16 <elucidator> if we are comparing it to X5
10:00:01 <sech1> and they have dual socket systems, those can probably match X5 hashrate, but with lower power :D
10:00:17 <sech1> as soon as Linux gets patched for 384 cores
10:01:39 <elucidator> yeah with dual socket system single mobo will be more power efficient probably, maybe marginally but still
10:03:09 <sech1> Waiting for proper Phoronix tests of this beast
10:03:16 <sech1> I think they have XMRig in their test suite
10:03:25 <sech1> but they're shit at tuning it :D
10:06:06 <hyc> hasn't Amazon by buying up all of Ampere's chips? or I'm misremembering
10:07:02 <sech1> Google has them too
10:07:22 <sech1> https://www.architecting.it/blog/gcp-c3a-ampereone/
10:10:58 <hyc> main point is, mere mortals aren't going to be able to buy these. 
10:11:18 <hyc> what can we get our hands on that matches that power efficiency?
10:14:22 <hyc> "The slowing of Moore’s Law has demonstrated a need for alternative processing architectures, which has led NVIDIA to become a $1.1 trillion company, greater than Intel and AMD combined ($161 billion and $170 billion, respectively).  Arm will quickly catch up, with a rumoured $52 billion valuation after IPO."
10:14:38 <hyc> had no idea Nvidia had outgrown AMD and Intel
10:14:47 <sech1> wait, AMD is bigger than Intel?
10:14:50 <sech1> 161 < 170
10:16:04 <hyc> I guess Intel has really fallen behind
10:23:12 <sech1> The highest efficiency CPUs avaiable to retail buyers are probably 7950X, and Ze4 EPYCs
10:23:23 <sech1> but they're all in 150-200 h/J range
10:23:41 <sech1> 7950X is <= 150 h/J after tuning
10:49:37 <elucidator> i wonder how the FPGA acquisitions affected those values, intel getting altera, amd getting xilinx
10:50:31 <elucidator>  $16.7 billion deal underscores Intel CEO's plan to expand chip maker's business...
10:50:47 <elucidator> AMD said it has completed its $49 billion acquisition of Xilinx, marking the largest chip deal in history....
10:50:57 <elucidator> hmmmm altera so cheap
13:32:00 <Inge> sech1: where were the zen2 cpu's efficiency wise for comparison?
14:27:32 <sech1> I remember they were above 100 h/J, up to 120 h/J for well-tuned rigs
14:34:33 <Inge> so still amongst the most efficient o_O
14:34:46 <Inge> oh wait, 150 h/J ... not j/H never mind :D
