ASUS PRIME X570 Pro review

@Hilbert Hagedoorn Please start pairing Ryzen 3000 with faster memory, it has quite a significant effect in many applications, and especially games !
DDR4-3200 just doesn't cut it anymore for these CPU's !

Example:
Your Time Spy CPU score: 10046
My Time Spy CPU score: 10719 ( https://www.3dmark.com/3dm/40959663? )

That is 7%, not insignificant !
In games it has quite an impact on minimum framerate, and a few percent too on maximum.
( I don't have the same games as the ones used for testing, but in those that I do there were measurable differences between 3200-CL14 and 3600-CL16, the latter winning all the time ! )

For Zen 2, higher MClock (in sync with higher FClock - Infinity Fabric) is MUCH better than that tiny "2" difference in Cas Latency !

Please use DDR4-3600 CL16 memory for any future tests of these CPU's, or ideally overclock it to 3733-CL16.

Check out memory bandwidth results by using DDR4-3800 CL16, yours vs mine:

That 7% is definitely not coming from a memory frequency increase. We test 3200 MHz as it is the current price/performance sweet spot. We do that for both AMD and Intel to create an equal and fair test environment.

Whoa..... The memory performance is just down right abysmal. Just like Wavetrex has stated there needs to be a standard speed to hit these CPU's with because 3200mhz is sorely sad.

I'll post a pic after getting the little ones on the bus, but my memory throughput makes everyone's on here look dated and sad as hell..... 3800mhz with an infinity fabric of 1900 makes the world of difference.

65gb screaming along with T1 timings 16-19-19-19-(32)...…"WHOOPS its 39 actually"

Where else would it come from ? It's just a 3700X running on Auto everything (It might be the motherboard is allowing more TDP headroom, but I didn't do anything special). There is no manual overclock.


That might be, but these CPUs are being held back by slower memory+ IF clocks.
The cores can access everything faster when IF is faster ! The speed doesn't come straight up from memory's extra bandwidth, but the fact that with faster IF, the latency goes down quite significantly ! Observe the AIDA64 screenshots... yours = 73, mine = 67 (It's 69 for Fclock = 1800, goes to 67 for Fclock = 1900).
CCX to CCX also gets visibly faster due to the same reason, so threads jumping between cores have less of an impact.

On Intel chips it doesn't really matter, 3200-3600 are "margin of error" close, but not on Ryzen.

Using ye olde car comparison... it's like having 400 HP engine on a luxury car and putting an electronic limiter to top speed due to regulations so the car never uses its full potential, barely reaching 250 HP.

So NO, on Zen 2, 3200 is just not good enough ! It's not sweet-spot at all.



Coming straight from AMD:

"Recommended Price/Perf Config"

I rest my case your Honor.

Thanks for review!

I'd appreciate if somebody could enlighten me regarding the following. I've just bought pretty much the same board: ASUS STRIX X570-F GAMING and pair it with 3800x. Further I have two m.2 nvme 4-lanes each: SAMSUNG 970 EVO Plus MZ-V7S500BW 500GB, M.2 2280, PCI-E x4, NVMe - installed right under the CPU, used for windows, and INTEL 660P SSDPEKNW020T8X1 2Tb, M.2 2280, PCI-E x4, NVMe - installed at the board's lower part, used for games. So the question is: do I have any PCI lanes left for other peripherals? I mean, if I install a sound card to the slot near the battery called (in manual) "PCIe 4.0 x1 slot (PCIE_X1_1/2)", is it going to steal any lanes from GPU or one of the M.2 NVMe devices, thereby crippling their performance?

BTW, none of the sata ports is/will be used, if it matters.
