People apparently still need to be told this:

What he writes also partially applies to SPECrate which is lacking against GB6 in a way: there's no sharing of data, just running multiple instances of the same benchmark. It's a good test for shared resources like L3 and main memory, but not very good for performance of cross cores exchanges, which as far as I know some of the GB6 workloads test.

That doesn't mean I don't agree with him on GB6 😀

Yeah i did alittle test run on my 9950X to check the scaling.
Seems like i'm getting ~30% higher MT score when i double the corecount from 8 to 16

First with CCD1 disabled -> 8core and 16 threads active on CCD0
View attachment 109361

Both CCDs enabled -> 16 core and 32 thread

Very valuable result, but unsurprising. Only the render subtest in GB6 seems to scale well with large number of cores. I guess each test has a different limit in scaling (didn't someone make a post about this in the past?).

Is it possible to disable cores in a finer way than a whole cluster?

Also I thought GB Pro version allowed to specify the number of cores, but I couldn't find confirmation on their site. I might remember wrong or they don't list that capability on their website or they removed that feature.

I think that depends on the BIOS. On my 12700K, I can disable whatever core I want as long as I keep one P-core active. On the Epyc ES BIOS, there are limited options available such as keep minimum two cores active per CCD out of the eight CCDs. Don't remember if it's possible to disable all CCDs except one.

Out of curiosity did you try GB6 with 4 cores on each CCD (8 total)? I would like to know how much that hurts MT score.
Should serve as a nice comparison point to the 9700X.

I'm hearing this funny movie trailer voice in my head: "In a WORLD where you can have only four cores on a single CCD, AMD has gone one step further and put TWO CCDs together. Experience the thrill of 8 powerful cores. Ready to take on any mission, no matter how impossible!".

Did it, though not that dramatic


No, that's not me by the way. Wish I could speak like that.

Here my runs with 9700X. (+200MHz auto OC, CO -20 all core) For the life of me I cannot get multi 20K.



7700X runs from yesteryear



It's as though AMD optimized Zen 5 for Geekbench 6.

This is my current memory timings. I think I need more CPU freq (5.8GHz+) I do think my CPU has room, but there is no option to push higher in the board's BIOS.

Got 20K finally but a cheat was employed. (Linux) It's the first and only run and maybe I can improve on it.

Employing *nix operating systems isn’t a cheat, it’s the performance you expect that Windows doesn’t give you by default.

Run the latest cachyOS and that GB score will increase even further I think.

I only checked the first result (inputting the run ID #) and notice you are using "balanced" power scheme in Windows. Change to 'performance' or 'high performance' profile, restart and then give it a whirl.

I would hope so. All the high-end chips' roads seem to converge to TSMC's capability. Seeing M4 scoring 4K in ST (at mere 4.40GHz), the next node AMD and Intel are on should be offering a similar ST performance. (not at 4.40GHz, though)

20C 265K vs. 12900KS 6000 MT/s: https://browser.geekbench.com/v6/cpu/compare/8495170?baseline=2861

Text processing seems to be the forte of Arrow Lake (good for compilation workloads I guess?).

Even against 32 threads, 265K scores a win in text processing subtest.

265K totally owns the 12900KS so looks like a lot of old Intel users can look forward to a decent upgrade in performance.
