    Phoronix: AMD Ryzen 7 5800X Linux Performance

    Over the past week we have looked at the AMD Ryzen 9 5900X/5950X Linux performance as well as that of the lower-end -- but still very powerful -- Ryzen 5 5600X. Today we are striking in the middle in looking at the last Zen 3 CPU model for the moment: the Ryzen 7 5800X. The AMD Ryzen 7 5800X is a $449 USD processor that is packing eight cores / sixteen threads, a 3.8GHz base clock. 4.7GHz boost clock, 32MB L3 cache, and has a 105 Watt TDP.

    RIP Intel and AMD is talking about Zen4 already:
    https://www.guru3d.com/news-story/am...4-already.html

    really amazing how it come from Zen to Zen 3 and beat Intel, like cat ate dog.

      Anandtech touches on this in their review article. Zen 3 is a new core, not an iteration of Zen 2 or Zen 1.

      In our interviews with AMD’s senior staff, we have known that AMD has two independent CPU core design teams that aim to leapfrog each other as they build newer, high performance cores. Zen 1 and Zen 2 were products from the first core design team, and now Zen 3 is the product from the second design team. Naturally we then expect Zen 4 to be the next generation of Zen 3, with ‘the low hanging fruit’ taken care of.

        The Ryzen 5800X based on the Zen 3 architecture is great, and the new Zen 4 architecture is going to be great too.

        But both Intel and AMD is going to be outperformed by Apple with their M1 processor. It's single-core performance beats anything, its IPC is so high.

          Apple ipc are RISC intructions..

          AMD/Intel are CISC..
          You are comparing Oranges to Bananas..

            Apple's ARM core is definitely interesting! It's heavily optimized for low power with its high IPC and low clocks. However, there's definitely still no free lunch and it's pretty bad in one important metric: area and cost efficiency. The cores are *huge* and need lots of chip area. AMD and Intel get significantly more performance into the same area, which lowers costs. In addition it's probably rather unlikely we'll see symmetric octo-core configurations of this specific ARM core any time soon.

              The benchmarks speaks for themselves, the Apple A1 is crushing it!

              Apple just started with M1 on the Macbook Air and Mac mini. Later they going to continue with the MacBook Pro and their Mac Pro workstations, so then they will probably do that when they have M2 and it will probably have symmetric core configurations. Maybe even 16 symmetric cores. It's going to crush both Intel and AMD.

                Yup you'd have to compare ARM instructions to x86 uops. Still though x86 really can't scale past 4 uops per x86 instruction and on average I think 3 is more common.

                EDIT: I really doubt we'll ever see an x86 architecture with like a 8-wide front-end. That is unless CMT-like architectures get re-invested in.

                  So?

                  AMD/Intel are CISC..

                  It makes no difference, it is perfectly valid to compare the two, be it fruit or CPU instructions.

                    Too bad that Apple decides what you can run on it. So it is still useless garbage.
