- pwr22I'm interested to know if the L3 cache all behaves as a single pool for any core on either CCD, whether there's a penalty in access time depending on locality or whether they are just entirely localised.
- magicalhippoProbably fun for those who already bought DDR5 memory... still kicking myself for not just pulling the trigger on that 128GB dual stick kit I looked at for $600 back in September. Now it's listed at $4k...Meanwhile I hope my AM4 will chug along a few more years.
- chao-Crazy to think that my first personal computer's entire storage (was 160MB IIRC?) could fit into the L3 of a single consumer CPU!It's probably not possible architecturally, but it would be amusing to see an entire early 90's OS running entirely in the CPU's cache.
- monster_truckThe extra cache doesn't do a damn thing (maybe +2%)The lower leakage currents at lower voltages allowed them to implement a far more aggressive clock curve from the factory. That's where the higher allcore clock comes from (+30W TDP)I'm not complaining at all, I think this is an excellent way to leverage binning to sell leftover cache.Though if I may complain, Ars used to actually write about such things in their articles instead of speculate in a way that suspiciously resembles what an AI would write.
- erulabs9950X3D2? AMD, who is making you name your products like this? At some point just give up and name the chip a UUID already.
- nexleBreakdown of the (semi-clickbait) 208MB cache: 16MB L2 (8MB per die?) + 32MB L3 * 2 dies + 64MB L3 Stacked 3D V-cache * 2For comparison, 9950X3D have a total cache of 144MB.
- 2001zhaozhaoI don't really see a huge reason to buy this other than it being a top-tier halo product.For gaming, AMD already pins the game threads to the CCD with the extra cache pretty well.For multi-threaded workloads the gain from having cache on both CCDs is quite small.
- ReaderiumCan someone explain if the 3D Vcache are stacked on top of each other or side by side.If they are stacked then why not 9800X3D2?
- fc417fc802Given that the dies still have L3 on them does this count as L4 or does the hardware treat it as a single pool of L3?Would be neat to have an additional cache layer of ~1 GB of HBM on the package but I guess there's no way that happens in the consumer space any time soon.
- sylwareWith the best silicon tech, in R&D, what would be the maxium static RAM(L1 cache) you could really slap to a 8 core CPU? (Zero DRAM).
- renewiltordI have a gigabyte of cache on my 9684x at home!
- jaimex2Can someone like... boot Windows 98 on these on a system with no ram?!
- tw1984that is larger than the HDD of my first PC.
- DeathArrowMy first computer had 64KB of RAM. My first PC had 8MB of RAM.
- throwaway85825It's disappointing that they had this for years but didn't release it until now.
