AMD Zen 5 rumours

With two Vcache CCD's, the OS only needs to keep the game on a single CCD....*any* CCD.

When the extra cache is only on one of the two CCD's, the OS has to first pick the correct CCD and then *also* make sure it keeps the game on that *specific* CCD.
Windows seems pretty decent at this now. Whenever I'm gaming on my 7950X3D i can see it park an entire CCD without issue.
 

reads like quite a big change to Zen chiplet design
reduce inter-CCD latency and improve power consumption (in low power states presumably)
 
Might be time to start the Zen6 thread
 
Per core vs per core maximizing offsets PBO

if I push my better cores to lower PBO some of the worse cores need a reduced negative offset not sure why why

Say a worse core might need -4 when other cores at their best negative but when not so optimized for best cores he worse ones might need way -10

If this is the case does this mean that in a completely optimised and stablE PBO vs non optimised per core PBO

The completely optimised one as some cores have lower negative offset say -34 vs -26 - would be faster for gaming where a few cores are used

But in rendering/cinebench/Prime95 where all cores completely loaded the most optimized per core PBO will be slower as your worse cores have smaller offsets ?

I can't remember exacts but with my 7800x3d something like the following two are stable

-29, -30, -4, -19, -27, -30, -12, -34

Vs

-28, -28, -11, -12, -26, -26, -11, -28

I'm guessing scenario 2 faster for productive scenario 1 for gaming

When running prime95 for number 1 the clock speeds are lower than for number 2 as when all fully loaded clock is max the worse core

You'd think in case two say core 8 would run at -34 but it won't unless core 3 is above say -7 and then all cores stable when that core 3 is at -4

There must be some odd relative voltages or loads between cores

Note both above were Prime95 Small stable for over 5 hours and same again for core cycler

these give a quick test of stability, but not 100% confirmation
then in two days you will get a random crash out of a multiplayer game and add +5 to all of above just in case
 
any eta on 9950x3d? AMD are sure taking their time:mad:
Some of the most recent articles say January, some day March. Waiting on the 9900x3d myself but all my Lian li stuff are still on pre order and looks like end of February for 5070ti so happy to wait. Be worth the upgrade from an i7 5960x and gtx 980 sli.

AMD hasn’t released pricing information for these chips yet, although we expect them to be released this January.

Where did you read January? Their CES presser stated March 2025, and haven't read differently anywhere. Curious to see where you read that! Ty

AH missed it - Thanks.

"Unfortunately, AMD hasn’t released pricing information for these chips yet, although we expect them to be released this January."

I am fairly certain that won't be the case! Wouldn't mind it though. Currently building a new rig and it's one of the last remaining pieces.

No worries, not many days of the month left to find out. I wonder if they mean release pricing information rather than the product.
