Good cpu for workstations but for gaming i keep it with intel, love my 10700k.

That SC score in CB20 and CPU-Z is mouth watering. My 3800X comes nowhere near that (just like the 3800X in Hilberts earlier test).
I'm very curious how the CPU would do with a per-CCX OC and with much lower voltage than 1.4V which in my opinion is impossible for the CPU to handle, even with extreme LLC. I'd go for 1,33V or something like that.
I've been able to do a 4425 MHz all-core OC which obviously wins over that 3800XT at stock by a pretty nice margin.

If you want lots of bang 4 your bucks take this:
R9 3900X (~410€)
MSI B450M Mortar Max (~100€)
Arctic Liquid Freezer II 240 (~70€)
32GB G.Skill Trident Z (nonRGB) DDR4-3600 DIMM CL17 Dual Kit @1T (~155€)
That '735 bucks' kit is 'stock' (only XMP on) faster in almost all cases! 🙂
My results: R15: 215/3182 // R20: 537/7247 // CPU-Z: 562/8514 - temps in a Silverstone PS07 Minitower 66.7 °C avg / 77.5 °C max after 8h prime95 torture with 4.133GHz/1.308V avg. on all cores.
IMHO: The 3900XT is a nice thing, but definetly NOT worth the money... and if you need high framerates in gaming take a 3600XT or a maybe more expensive Intel setup depending on the CPU that is chosen.

In all honesty these XT Cpus dont really bring anything good. One can see well in the 3800xt review, that the 3800xt is bad chip and the 3800x from the old review was better. Since the Power Usage is way higher on the 3800xt MT and the OC is not rly possible. And on all three reviews you can see that MT power usage is way higher on the XT parts as compared to the X parts, whilst the Performance is basically the same... The only interesting this is the 3900XT using significantly less in idle, as compared to the 3900X.
Perhaps one tip for you Hilbert, you write always for the OC, to set 1,4V and up the multiplier, to my knowledge the zen2 cpus are rather voltage sensitive (from other forums) and one should not up the voltage over the max MT voltage that the cpu uses with Precision boost, which is mostly under 1.35v, or even under 1.3v, depending on each individual cpu. Hence perhaps you determine first this Voltage and than oc at this voltage (my 3900x can do 4100mhz on all cores at 1,0V, but above it needs disproportionally more voltage for just a few MHZ gains and than its starts to massively gain temperature - on a custom Waterloop with EK Block and two 240 radiators), same goes for another 3600 that i have in a htpc, but if i run them custom oC on a lower voltage, they have higher MT scores, a bit lower ST scores and use significantly less power as compared to stock.

can't add call of duty warzone to benchmark ?

I wonder if they if they will hit higher IF clocks, might be more worth while if they can.

Seeing this only makes me wanna say:
careful AMD, don't slip up now.
buhehe
I really disagree with the Recommended award. Such a pitiful increase in performance for so much more money... and heat.

A strange and useless release these XT versions, they add very little performance and are much more expensive than the non XT parts. And to make things worse, Ryzen 3 is on track for a release near the end of the year...

So the X variant can be had for as little as £270 new and the cheapest ive seen the XT is £447..... i paid £325 for my 3800x 2 months ago and now the same seller sells the same x version for £270....if they wanted better sales on the x why not just drop the price in the beginning, also there are going to be some sweat deals on second hand 3800x from now on, with better thermals and only a handful of fps less for essentially £80 less why would anyone choose the XT now.

I guess my year old 3900x with r20 531/7382 should be renamed to 3900xt Super. 😕

Whaaaat?!?!?
How did you cool that?
