Yeah I can see 7700x beating the 7800x3d in games that likes clocks more and not cache , wonder what the actual speed clocks on the 7900x3d and 7950x3d on the ccd with the cache

AMD Unveils Three Ryzen 7000X3D V-Cache Chips, Three New 65W Non-X CPUs, Too
3D V-Cache to the masses.www.tomshardware.com
so like hybrid without e cores

This... it seems a little 'weird' to have 2 different ccd's but I suppose it's no worse than performance/efficiency cores on intel.... assuming windows etc can determine and make use in the best way (meaning windows 11 only probably)
I'd have also thought there's potentially missing performance from not having 2 3d cache ccd's...
The performance difference between CCD's 'should' be a lot closer than P vs E cores though.
That tom's article mentioning 'AMD is working with Microsoft on Windows optimizations that will work in tandem with a new AMD chipset driver to identify games that prefer the increased L3 cache capacity and pin them into the CCD with the stacked cache', is interesting but is this gonna cause issues like Intel's thread director, so you're reliant on MS or you'll have to use process lasso?
Personally I would have just liked both CCD's to have stacked 3D cache, so we're reducing the need to know things like is the thread/process that's just spawned going to the core on the right CCD.
Maybe the next gen of Ryzen we will get more than 8 cores on a CCD and that will alleviate these kind of design decisions a bit.

was mentioned the performance increase wasnt worth it for the extra cost games above 8 cores doesnt do much and would probably have to lower clocks which would reduce multi workloads , but we can see where its heading bring on zen 5 3d
AMD Provides More Ryzen 9 7950X3D Details
At CES 2023 AMD finally unveiled the much anticipated Ryzen 7000X3D CPUs. In this interview Gordon talks with Scott Stankard, Director of Product Management ...

Yeah I was thinking very selective benchmarks.
Who the **** plays Dawn of War 3?!Some of these claims are bit strange to me. I'll take two for now.
If we look at CS:GO for example, AMD is claiming 23% gains.

PC gaming would be crap with only one arm.
Two legs and 1 kidney is survivable and you can still use KB AND mouse.

the usual cherry picking
And resolution which indeed shows the difference better but no one games at 1080p, no one that these CPU's are aimed at. 4k and 1440p for real world usage is what we need.

M guess is up clocks and lower voltage through various optimizations, Basically 4770K to 4790K.
If only the thermal performance of the staking is an issue limiting the max speeds (that is the stacked part cannot transfer heat as well), and it's not something to do with voltage planes etc., then since the stacking is only over some of the die, could they not have give the non-covered cores a higher turbo bins?
Although the images of this show the 3D V-Cache in the middle, this WikiChip one shows it in the middle anyhow, so it can't be that:

Anyone consider moving from adler lake or raptor to zen 4 3D needs their head checked, especially if gaming at 4k. The games they showed does not exactly get the me excited for it, could be a very mixed bag in performance.
Be amazed if they can get it to 6.2Ghz boost compared to 6.0Ghz of the 12900KS.
Soldato
My guesstimation is the 13990K or whatever the end up calling it will basically just be a 13900KS with lower voltage.
Definitely going to wait for reviews as all I’m really interested in is any change to 1% lows at 4K.
Think my 7700X stop gap cpu might be staying in for longer than I’d planned!
Being an early adopter of AM5 has been quite smooth but going for a 7950X3D and hoping that windows can schedule the correct CCD for optimal performance be it frequency or cache, sounds like a challenge that could take more than a little while to smooth out!

Would get slated in reviews though, as would be identical performance etc. They have to make it 5% faster at least, only way to do so is 6.2Ghz clock, which I don't think they can get out of 10nm. We'll see, mystery at this point!
