updated BIOS for x470 chipset won't come till 2021 they say.

[Metroid]

I have a msi b450 gaming plus board + 3600, if there is a bios for my board then yes i will upgrade to a 5600 if not then not sure, 5nm ryzen will take at least 2 years.

amd ryzen zen3 5900 reported to have SAME HASHRATE as 3900x ~13500khs

[MA3A]

without mining software updates. WITH CURRENT MINER VERSIONS.

which is a bit saddening. However i expect about 15khs after miners updates.

64->7mb cache plus 16+16+16+16mb cache in 3000 series vs 72 unicache for all cores. Stock freqs are same except TURBO mode, when 5000 series is a bit faster.

we shall see.

In local store all amd ryzen zen3 (vermeer) 5950x and 5900x series were sold out instantly, the 5800, and below are not and plentiful available.

By the way the AMD ROADMAP shows AMD ZEN4 (pcie5.0) for 2021 and ZEN5(pcie6.0 ?) for 2022... New socket comes out in 2H 2021 afair.

zen 4 by 2022 q2/q3 only because intel by 2021 q4 will have something more or less good, roadmaps are done to assure investors, nothing to do where the company is going, remember that competition drives people to outdo themselves, so if nothing from intel by q4 2021 then zen 4 only when intel has something more or less good.

Don't expect any miner software improvements. Zen3 has no new features, just better performance.

You're not entirely correct about that. Zen3 has vector AES, for starters. 5600X will be arriving to my postbox tomorrow

[philipma1957]

Was not able to get one.

Have to settle with my

 4x 3900x
 1x 3960x
 1x 3970x


to be honest I wish I had 3x 3970x and nothing else.  but they were very costly.

[MA3A]

Well i am hoping the programmers can utilize unicache on zen3 somehow...but if not then 3900x or 3950x are fine with me. I get the point about roadmap, but it still shows the point that zen4 is coming very soon if zen5 already in works. Thats what we know. I am sure there things that we dont know. I had a buddy who has worked for intel, they had materialized cpus like 3 to 5 years ahead of announcements...

[miner29]

Im still running my pair of ol' 2970WX's and waiting to see where the dust settles on the newest round.  Must say exciting stuff AMD is whipping out these days!

I don't think so, VAES requires AVX512. AVX512 is mentioned for Zen4 but no mention of VAES.
They still need to improve AVX2, that will also likely have to wait for Zen4.
Zen 3 mostly improves single threaded performance.

IMO AVX512 is a bust. It's over 4 years late and still not available on mainstream CPUs.
And anything AVX512 can do, a GPU can do better.

Edit: THG says Zen3 implements VAES for AVX2. This is a non-standard implementation that backports
the 256 bit 2 way parallel AES from AVX512 without requiring support for 512 bit vectors.
Like the rest of Zen AVX2 it's probably only for show and breaks it down to 128 bit serial operation internally.

when do they have new threadrippers coming out ?

I'll get 5600X today and will test it to see how VAES performs.

[Metroid]

I believe the 5xxx series will be 20 to 25% higher hashrate than the 3xxx series overall, will see.

have anyone seen real hashing of 3950? On the internet values are sooo different, starting from 13khs up to 20khs...like whats the stock clock hashrate with good board/mem timings, but WITHOUT OVERCLOCK...

With top notch RAM (3600 Mhz, CL14), properly set timings, and a moderate all core overclock (4 Ghz, @1.15v), it's a tad over 17khs (28 threads used), probably closer to 18khs on Linux.

13500 slight downclock.  I had one sold it.

I set power to 1.01 volts and freq to 2900

I have both 5600X and 3700X now. I've tested them both at 4.1 GHz with heavily tuned memory. 5600X is 1% slower even though it was running DDR4-3800 14-13-13-28 (tRFC 236) and 3700X was running DDR4-3200 14-14-14-28 (tRFC 240). So Zen2 had slower RAM than Zen3, but it pulled 7788 h/s with 12 threads @ 4.1 GHz, and Zen3 pulled only 7728 h/s with 12 threads @ 4.1 GHz. The main reason is that L3 cache in Zen3 is significantly slower: available bandwidth per core is only 50% of that of Zen2.

But overclocking changes everything: 5600X @ 4.7 GHz can pull 8780 h/s - https://xmrig.com/benchmark/cnH6D397CAU - this is a record for 6-core CPUs. Zen2 can't do that with air cooling.
