Is the problem related to low voltage thresholds like 1% or 0.1% causing serious drops in CPU threads during intensive games if communication between threads on different cores is needed? Has this been resolved for Ryzen 7000 anymore? Are all Ryzen 7900X CPUs built with two 6-core CCDs and every 7950X with two 8-core CCDs, or are there exceptions like some 790X models using an 8-core plus a 4-core setup?
I haven't been keeping up with it personally, but the question brought back a thought: in the second part, AMD has only ever provided the same number of active cores across their CCD lines, meaning an 8+4 setup isn't available. I'm not sure if combining the 16-core model and disabling cores manually could work.
I noticed that too. This game took a heavy blow—it's not great. Turning off SMT helps occasionally, but with 8 cores it's still thin. If it needs to switch to another setup with potentially more cores, like 16 or even 12, then having them all on one CCD/ring would make a big difference.
Observed issues with my 5900X. I’m hoping future 3D chip releases will support overclocking similar to regular Ryzen. Otherwise, it runs smoothly for gaming.
It seems you're comparing two CPU configurations: one with an 8-core processor featuring SMT, and another with either a 16 or 12-core processor also using SMT. The discussion centers on whether the dual-CCD latency in the 8-core setup is preferable. Let me know if you'd like a clearer breakdown!
If you're concerned, try the 5800x3d now or hold off for the 7xxx3d, checking reviews at your convenience.
The problem remains consistent across models like the 5800X3D with a hard lock on 8 cores. It offers benefits from extra cache, but if certain titles run well without High Bandwidth Memory disabled and even gain some performance beyond 8 cores, it will still face latency penalties when more than 8 cores are available. It’s unclear whether any games truly gain from using more than 8 threads, nor does it appear that many older titles benefit significantly from HT or SMT off. It seems most modern systems have moved away from this approach, and even with e-cores on some games, the gains are limited unless you have a very powerful setup.
ecores don't do anything for gaming, HT off normally gives about 100-150mhz more due to less heat, freed up power budget. As for 16 vs 8, some games do benefit from it, but not alot, msfs, 2077, hitman, forza etc. There are too many moving parts atm, cpu, gpu, even psu With the info thats public im leaning toward 7800x3d (8cores) +cl30 ddr6000 and i'm still waiting on amd gpu benchmarks
