Review AMD Ryzen 9 3950X Review: 16 Cores Muscles Into the Mainstream

[joeblowsmynose]

From base, sure. But from rated all core boost? Not by much. With Ryzen it is essentially better to just leave it be and use PBO.

As you said if you set an all core clock then power draw increases pretty insanely. I saw one review showing the 3950X at 4.3GHz match a 9980XE at stock.

I have no idea what Zen 3 will bring. I like anyone have to wait for its release and until then expect the same crap rumors as before like it will be a 32core 6GHz+ monster with 64 PCIe 5.0 lanes with 128GB of integrated HBM 3 memory on die.

All core boost is also pretty low on that chip at 3.2 I believe, which explains its low 65w TDP --- one core boost is 3.7 or 3.75 if you have a good cooler.

It was an amazing bang for buck CPU if you could get it on sale and like to OC.

I guess the 2700x is practically free these days, so that's the new bang for buck champ from AMD (and maybe r5 3600)

I'm excited at the cache changes in zen3 ... that might increase some gaming performance. (larger, unified L3)


Edit: just rechecked the boost stats here: https://en.wikichip.org/wiki/amd/ryzen_7/1700

3.7 (or 3.75) for two core boost and more than 2 core boosting is just 3.1. Anyone who didn't OC their 1700 is/was losing out on a lot of extra performance.

I just received my new build. Asus Prime X570-Pro MB with my ryzen 3950x. I have 32 gigis of 3400 speed ram. How can I increase the turbo boost speeds? It seems to hang at around 3.9 - 4.2 in core temp graph under 100% load during my vray renderings.

The best method of getting higher turbo boost speeds is to have kick-butt cooling. The Ryzen 3000 cpus behave very similarly to Nvidia's Gpu Boost: frequencies are determined by power and thermal headroom.
It will try to boost as high as it can depending on that headroom. These cpus are trying not to kill themselves.
So if you can slap a 360 or 280mm AIO on top of that... but if you're not comfortable with liquid coolers:
Noctua NH-D15S / NH-U12A
Thermalright Le Grand Macho RT
Deepcool Assassin 3
Scythe FUMA 2
Cryorig R1 Universal

Manually OC? For all core 100% loads it can help, but the caveat is that you'll lose some single thread performance from stock.

But as Phaaze88 said, good cooling is a must with the CPU if you haven't already got it.

You should (hopefully) be able to hit 4.2 (rock stable) with all cores with a strong cooler and a decent mobo; don't expect more than that. Again this will only somewhat increase all core performance, and cause detriment to single core perf. The native boosting on the 3950x is pretty much at the limits of the silicon. Unless you like to tweak and OC, I probably wouldn't even bother. But as a fellow 3D artist, I know you can never have enough rendering speed, lol.
