    I wonder what AMD's Zen 4 Raphael that would be an APU and won't increase the core count would do against that?!
    I guess Raphael will be in the most optimistic case a 16-core with Navi 2 iGPU?!

    Latency will be the wildcard for gaming. A lot of games prefer latency over bandwidth. Intel has a cool util called "vtune" that you can run and see where the pipeline bottlenecks are. When our group ran that across many games, we noticed latency was more often preferred esp on older games.

    High spec DDR5 will have great bandwidth but will be running with dividers to get there which will cost you more and more latency. I'm personally not excited about CL50/8400 for example.

    So there's going to be a lot of testing needed by people who know what they're doing to determine best all around vs what's best for a specific use case such as esports or high fps gaming.

    Off the top of my head the following should be tested on a 12900k:
    - HT off
    - Small cores disabled
    - Per core OC vs all core
    - DDR4 tuned DR B-Die 1:1
    - DDR4 tuned DR B-die maxed frequency
    - DDR5 tuned for max frequency

    If I had the time, I'd be testing the above for my use cases. Having to buy 2 boards and 2 sets off diff mem would be a bit annoying to swap around but not undoable. Thankfully a few people in our group will get ADL so the data will be more finely tuned that what you'd get from a tech tuber/publication. I'll post it here as it becomes available.

    I just wanna see gaming RT benchmarks, all these synthetics are so boring and useless for me. That's the big ? I have.

    These benches are boring like other ppl have said get the gaming benchmarks going maybe AL maybe isn't that great for games that's all I want it for nothing else .

    I do wonder if AMD will pull and Intel, and once they announce the release date, AMD will drop their new faster parts as well, just to muddy the waters and stop people pre-ordering. Will be interesting to see what games are played with this critical release for Intel.

    If it was going to be significantly better thsn AMD in games Intel would be making sure everyone knows.

    These leaks I'm sure are pre-planed, its always the same apps in the same order these people leak numbers for like the have some kind of advertising deal with.

    If one is going to leak something why kinda half ass it kinda leaving people not really knowing what its going to be like unless they just making **** up.

    I'm wondering if we aren't seeing gaming benchmarks maybe alder lake isn't good for games just a thought that's all.

    That's what happened with Rocketlake. Lots of leaked CPU-Z and Geekbench scores and then gaming was meh.

    It seems it may be a thing of the past as well, in some caps


    Geekbench is going to shortly remove the ability to store results in its database for any unreleased model names - so testing an unreleased CPU in geekbench 5, the result won't be visible on the internet

    This won't stop the actual person doing the test to leak their own test themselves, but it stop dataminers from finding results

    Something tells me the scheduler for big/little cores on alder lake is going to be bad for games, or not that much of a leap over zen3

    Thats the only reason I can think of why Intel is happy leaking all these dour productivity benches and not gaming ones

    Suits me if true, means i can get better DDR5 as well in a year or so time :p

    No gaming benches isn't good thought we may have seen some buy now .

    Gaming benchmarks are not exciting, as everyone knows the outcome already.

    The outcome is that in 2021, 4K is the intended/desired/best resolution to be running at, at which all CPU's are GPU limited, and will be for many years. Now this statement of mine will be attacked by those who like playing at below console resolutions of 1080P, 1440P and that are stuck in the past. They'll defend their 1080P CPU benchmarks to the end of time. Let them, they tend to be the noisiest and the type of poster online 10 hour a day refreshing every topic of concern to them.

    All you need for 4k gaming, even with a 3090/3090ti will be a Zen3/10th/11th/12th gen CPU with 8 cores, clocked to moderate levels. You'll see no diference in FPS between any of them.

    I don't really agree, I think the 12700K/ 12700 (or above) will obsolete AMD's current Zen 3 lineup, assuming high end cooling is used. Part of the reason for this, seems to be the improved L3 cache.

    There's definitely some games that can fully utilize current CPUs, such as recent Total War games. Watchdogs: Legion CPU usage is pretty high too. Sounds like Farcry 6 will benefit from higher IPC/ singlethreaded performance also.

    I think the extra 4/8 small cores will only be useful in multithreaded benchmarks, or vs the Ryzen 5900X or above.

    Maybe AMD will be able to compete with Alder Lake, by beefing up Zen 3's cache, but I think these CPUs will have premium pricing.

    Another factor, is that Intel will be slightly ahead of AMD on transistor density, until Zen 4 CPUs are available. Intel's '7' fab process (an optimized 10nm process basically) is slightly ahead of TSMC's 7nm (the standard, non EUV version).

    What about the 4090/5090 though as some people like to keep the CPU for a few years and will upgrade their GPU in that time so while a faster CPU is not going to benefit now it may do in a few years time.

    It would be ok for gaming at 4K with a very expensive graphics card and system. For anything it’s pretty meh.

    A RX6900 XTXH would be a better pairing with a 9900K. It will get most performance out of the 9900K.
