need help choosing right cpu

[drifting silo]

hi, i need help choosing the right cpu for the job, currently running a r5 3600, but want to upgrade to something that doesn't bottleneck my gpu, a 3070 with an overclock, and is willing to render fluidsimulations and other intensive tasks. just the cpu. not the motherboard and ram. (although i am only running 32gb at 3200mhz) I have a 240 iao, so i should be good cooling a decent cpu. any suggestions?

[floral sparrow]

7600 is always a good option

[drifting silo]

yeah but thats am5

[dawn fiber]

5600x would do

and it's am4

the 5700x and 5700x 3d are also good options depending on ur budget

[drifting silo]

alright thank u, got a big budget so im thinking about a r7 or r9

5th gen ofc

[drifting silo]

5000 series i meant

[dawn fiber]

5800x 3d is the fastest am4 cpu money can buy

[lone elk]

5700X3D, anything else won't actually feel faster

and 5800X3D isn't worth the extra $100 for 1-3% more FPS

240 AIO is more than fine

other route would be upgrading to AM5
going wih a 7500F processor would be the best bang for buck, performs about the same as the 5700X3D

but platform upgrade comes with B650M motherboard cost as well as DDR5 memory cost, probably not worth it yet; still tad too expensive

so 5700X3D

[dawn fiber]

since when was the 5700x 3d that much cheaper

that's crazy

[lone elk]

can buy the 5700X3D here in NL for €190 at the moment

5800X3D still going for €330

[dawn fiber]

it's literally the same thing with lower clock speeds

what a deal

5700x 3d is the one then by the sounds of it

[lone elk]

yep, and in most games clock speeds don't matter much (compared to cache)

so pretty good deal indeed

[dawn fiber]

most games want better single core performance

[lone elk]

tell that to the UE and RAGE engines

[dawn fiber]

real 😭

[lone elk]

7500F currently available here in NL for €144

so that's a stellar deal too

no gamer needs the iGPU anyway

think the pricing around other parts of the world are the same

as AMD usually sets the price globally

[dawn fiber]

unfortunately am5 motherboards can be expensive and ddr5 ram is insanely expensive here

OP asked about fluid simulations. Not games?

Not saying x3d is bad at all for fluid simulation, but most tests i see online are for EPYC. Hmm

I dont know enough, sorry for muddying the water

Openfoam CFD

[tiny flower]

Wow

[lone elk]

The moment you really ramp up fluid simulations, not a single consumer processor is gonna fit the bill

At that moment you need the expensive 128-core EPYC stuff

Which the HPC guys at your university might be willing to help you out with

[lone elk]

Yhh that 64MB extra L3 can be helpful

[drifting silo]

Dahm well i am a bit late to the party, but thanks very much. Ill go with the 5700x3d then.. i live in NL too, so the 5700 would be the best bang for the buck indeed. Thank u.
