I seriously doubt 12P cores on Intel's last gen architecture and node is going to beat 9800x3D. And if you need more cores, there is 9950x3D. I know it is not on one CCD, but I think AMDs more efficient and modern core design, along with the vcache will more than cancel out the latency penalty of dual CCDs. I'm not even sure it will beat 14900K. It all depends on what sort of frequencies they are able to get at a manageable power usage. If they have to sacrifice clockspeed to get power and temps under control, I dont hold out much hope for significant improvement over 14900k.
9950X3D is a hybrid design only one CCD has 3D vcache deal with beside just being dual CCD
If this 12 P core becomes reality, its set and forget as all 12 P cores on one ring bus and still a modern arch and 7200 RAM will get close to competing.
It probably beats 14900K as the 4 e-core clusters of 4 e-cores each are slightly larger than 4 extra P cores in their place and slightly more power hungry are they not?? Only reason Intel went with e-cores is because they are more space efficient per multi threading performance and perform better for apps that scale up to tons and tons or even infinite threads than putting 1 P core in same amount of space.
But you would want to leave HT on unlike on a 14700K or 14900K and that adds power and heat too!! Otherwise you downgrade form 16 threads to 12 threads even with extra cores.
So you would want 12 cores 24 threads.
And also if Zen 6 rumors are true, if and when this comes out you will only have a 1 year or 1 year and months wait or maybe slightly longer wait for 12 core single CCX within CCD Zen 6. I just hope it has WIN10 drivers and works fine with WIN10. Cannot stand WIN11.
