An X3D CPU, but not for gaming !

[softwaresimian]

Anyone have a view on this ?

MongoDB likes lots of memory and fast cores. I'm curious if the extra cache of X3D, of say the 7800X3D, would give better performance than the faster clocks of the 7700X ?

AMD Ryzen 7 7800X3D Review - The Best Gaming CPU

AMD's Ryzen 7 7800X3D is everything that gamers want: eight fast cores, in a single CCD, with 3D VCache stacked on top at a price point of $450. In our review we can confirm that 7800X3D is indeed the fastest gaming CPU available, beating Intel's 13900K and even the 7950X3D.

Says (about middle of the page) the 7700X is the better chip by a small margin for that use.


EDIT: This is the problem with the 7800x3D though it is a great CPU for gaming - the 14700K absolutely obliterates it for uses like this:

Intel Core i7-14700K Review - Catching the 13900K

Intel Core i7-14700K is the only processor released today with an upgraded core configuration. Thanks to an additional four E-Cores, more cache and a 200 MHz frequency bump, the 14700K reaches performance quite close to the 13900K, at much better pricing.

For lots of parallel type workloads cache is/can be a great benefit.

For that you have to look to the 7950x3D (or 7950x) which are much more expensive CPUs again - although there are some decent deals on them cropping up currently if you look around.

Shame workstation CPUs and motherboards have gone to silly money for the most part now - 10 years ago you only had to pay a moderate premium over the consumer desktop platform to get into the HEDT/mid-range workstation systems which were suited to tasks like this.

Without some benchmarks of that specific app/workload it's impossible to say, but at the same price, the 7900 is usually a better productivity CPU than the 7800X3D.

Without the user's specific setup it is difficult but there is a MongoDB benchmark in the middle of the page on the links I put above - it isn't really an application which plays to the strengths of the AMD CPUs by the looks of it - the AMD CPU results are 2-3 generations behind Intel in that specific usage.

Oh, I didn't notice. From the results, it looks like cores and single thread, but not cache, though I don't know how representative the benchmark is for the OP's workload.

Thanks everyone for the info, some interesting things to consider.
