Question High-TDP Threadripper vs low-TDP newer Epyc?

[rust_0]

At around the 2000 Euro price point, which would be the better choice for a general purpose server in terms of raw performance: A Threadripper 3970x or an Epyc 7413?

The additional PCIe lanes of the Epyc platform would be great for expandability, but CPU performance is the number 1 priority. Can the newer 7413 still outperform a 3970x despite having a 180 W vs 280 W TDP?

Looks like, that 3970x does have much more performance(f.i. 32 cores/64threads vs 24 cores/48 threads and higher clockrates for 3970x).

Zen 3 is very strong, so I would go with Epyc. Assuming the board is affordable.

Thanks for the replies, after further consideration I've decided to trust AMD's Zen 3 R&D and go with the Epyc. I can't even imagine what kind of beasts Zen 3 Threadrippers will be once they hit the market!

Iso-power, Rome (Zen 2 Epyc) is very competitive, if not better than Milan (Zen 3 Epyc) in many MT tasks. So a 3970x with 3.7/4.5ghz base/boost on 64 threads almost certainly have better CPU performance than EPYC 7413 with 2.65/3.6ghz base/boost on 48 threads, especially in MT tasks with 100w more power budget.

This is general purpose server, not Cinebench. Epyc also has 8 channel memory. It deserves nothing less imo.

We are also getting Zen 3 Threadripper soon-ish, so if you wait, you can have the best of both worlds.

More memory channel is more important than MHz for servers.
