    I have a dream for the new Zen series, Since they're moving to 8 core CCX layouts I'd love to see more core/thread options. Currently they've got multiple pretty useless SKUs that don't really differentiate all that much. Why buy the 3600x when the 3600 exists? Why buy the 3800x when the 3700x exists?

    I'd love to see something like:
    4950x 16C/32T
    4900x 12C/24T
    4800x 10C/20T
    4700x 8C/16T
    4600x 6C/12T

    I for one would fall over myself for a 10C/20T part that's the same price as the current 3800X and roundly spanks Intels much more expensive 10900k

    I doubt we will see a 10c/24t - Just purely from a marketing POV let alone performance... Given the 3900x is cheaper than the new 10th gen 10c/24t Intel, it wouldnt make much sense.

    Edit: I am holding out for a 4900x though! - Currently have a 3900x on x570.. This chip will end up in my esxi host and can retire the 2700 on x470(yay, can keep the board)

    https://www.techradar.com/au/news/amd-ryzen-4000-leak-hints-at-16-core-ryzen-9-3950x-successor
    some info

    4700x 4.6GHz/3.8Ghz (+200Mhz boost, +200Mhz on the base) shipping with wraith spire 45w CPU down from 65w
    4900x 4.6Ghz/4.0Ghz (same boost +200Mhz on the base) 65w CPU down from 105w
    4950x 4.6Ghz/3.7Ghz (-100Mhz boost, +200Mhz on the base) 105w CPU

    So we are looking at probably a 5% increase in base clocks.
    17% increase in IPC
    Significant 30% decrease in thermals
    So we should expect a ~ 23% increase in ALU and integer performance, 58% increase in FPU.

    So upgrading to the next size up combined with the IPC and clock increases will see a healthy gain.

    Going from a 8 core 3000 to a 12 core 4000 should see something like a 90% increase in ALU performance and a 140% increase in FPU/Encoding. Same thermals.

    So it would seem to be worth upgrading in a socket, particularly if you upgrade to more cores, if your gaming and workload supports multithreading.

    Given those leaks are A0/Beta steppings.. If we look back to 3000 series.. A0 was 100-200mhz slower than retal steppings; So we may see higher boost clocks then this yet.

    Either way IPC is more important to me (gaming is less than 5% of the desktop usage). So its a huge win.

    Q3 is going to be fun and expensive... New CPU & GPU times!

    I dont understand the 17% IPC increase, is this due to better latency in the cores, i.e. less Chiplets? 3100x vs 3300x.
    i mean they got what 5% from zen1 to zen1+ and 15% with a die shrink.
    im sceptical but very much want to be provedn wrong!

    Even at lower clocks, it still seems likely 4000 will be a significant boost.

    I don't expect boost clocks to go up much higher, but base clocks are obvious for improvement, because the 30% power reduction will allow that.

    Not just improvement in latency.. It has to be improvement in the core itself not just trans core/chiplet coms.

    For 17% improvement its most likely something like completely redoing cache and branch prediction as well as other improvements tweaking the ALU itself. 50% FPU increase, basically means wholy new FPU design. A whole other FPU unit basically.

    It's not just a die shrink like Zen+ was, this is a whole new architecture. So it's 17% IPC improvement from the new design + speed increase/latency decrease form the unified L3 cache + a clock speed boost.

    Call me crazy but these might end up 25-30% faster :S

    rocketlake supposedly to be on 14nm. revised architecture. will be interesting. maybe amd will finally overtake intel.
    how long has it been? over ten years?

    when was core 2 released 15 years ago?

    As far as i am concerned.. AMD over took Intel quite a while ago.. Saying 1 workload (gaming) is the primary deciding factor of performance is silly.. Its no different to cars.. Straight line performance does not win at the track.

    Given the big four cloud providers are moving workloads to AMD... Netflix moving to AMD kinda proves AMD has won this gen and the last gen - given the lag in enterprise deployments.

    And the heat and power reduction! I'm sure those server farms have some pretty frothy loins at the thought of a 12 core 24 thread chip at 65 watts

    And its not just the power.. its the all round improvements. E.g. For Netflix is was the huge amount of PCIe lanes available for storage and networking performance improvements.

    anyway its IPC at what? cinebench 20?

    FPU is going to double for some things, with better AVX support i believe.

    right now AMD is ruling because of Jim Kellers Zen. noone is better than him. Jim Keller is gone from AMD now. He moved to Intel. so I think Intel will rule over AMD again in a few years when Jims Intel designs make it to market.

    Don't think any server farms would be deploying 12 core parts. Density is still a factor.

    They are at 3.125w/core now... Wait till next gen!

    Gaming performance probably won't be mind blowingly faster. Really thats a GPU factor these days. Still probably see +10% in gaming improvement.
    Encoding and FPU will be the dramatic changes. I imagine AMD will be in high demand with HPC applications.

    AMD has a tremendous IO advantage, thats been the case since Ryzen 1.

    Agreed but it still that reduction shows promise for the 64core parts

    I believe Jim Keller is working on Intel's GPU program - https://games.mxdwn.com/news/intel-on-track-to-release-intel-xe-graphics-on-2020/

    Also AMD's Michael Clark (who took over from Keller) had a greater role in Zen's arch design that is commonly recognised;
