Question Advice between i9-14900k and amd ryzen 9 7950x

[manwhocantdecide]

Hello,

Im currently looking to upgrade my workstation and i cant decide between these two processors (i9-14900k and amd ryzen 9 7950x).
I am primarily looking for a processor most suitable for deep learning. I expect high ram usage and wish to have as much ram available as possible.
Furthermore i do not expect to upgrade very soon thus if it uses the lga 1700 or am5 is of no concern future proof wise.
I will primarily use my graphics card, the RTX 4090. However the processor should still be efficient at loading data.
i also expect to do a lot of offloading of parameters and data to memory. It is not meant for gaming.

It is difficult to make a good comparisons since most benchmarks are for gaming.
and any deep learning benchmarks are on the cpu only and not for dataloading or parameter offloading.

Thanks in advance for any advice!

14900k because it has 24 cores and 32 threads and can turbo to 6ghz while other has 16 cores 32 threads but less turbo so think you be gaining more with 14900k

If you have an app that can fully load all 32 processing threads, a case can be made for the 7950X
OTOH, many apps have single thread limitations, and to that end, the 14900K will be better.
Here are some passmark comparisons:
cpu #threads full workload/single thread
R9-7950x 32 63418/4312
I9-14900K 32 60672/4758
I night add that ryzen is fussy about ram compatibility and performance; it depends on fast ram to perform well.
Intel not so much.

If your goal is lots of ram, I would say 14900k, with a DDR4 based board. Getting 4 sticks of ram, for 128gb, on DDR5, has been a challenging endeavor for people. With DDR4, you can get a proper 4 stick kit, for 128gb. Something like this.

Thank you very much. Is it true i can go beyond 128 gb ram with ddr4 using the intel i9? And what kind of trouble can i expect with ddr5? I wish to also work with large knowledge graphs. If possible i would surely like the faster acces times of ddr5 for querying.

Yeah ive read about this aswell. Thank you.

If you want more than 128gb, then you need to be looking at an HEDT like Threadripper.

192gb is possible if you will go DDR5:

That's the first 4 stick kit, that I have seen, on ddr5. Nice find, but that price, wow!
