The AMD Ryzen 9 3950X Review: 16 Cores on 7nm with PCIe 4.0by Dr. Ian Cutress on November 14, 2019 9:00 AM EST
Test Bed and Setup
As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

nathanddrews - Friday, November 15, 2019 - linkThat's typically the main problem: minimum frames. Across most benchmarks, Intel can maintain significantly higher minimum frame rates for 144Hz and up. Obviously these metrics are going to be very game-dependent and settings-dependent, but the data are very clear: Intel's higher frequencies give it a significant advantage for minimum frames.
treichst - Thursday, November 14, 2019 - link165hz monitord have existed for a while now. 240hz monitors exist from a number of vendors.
RedGreenBlue - Thursday, November 14, 2019 - linkThe reason this is okay is the same reason a lot, or most, car engines advertise a.b liter engines when in reality it’s about a.(b - 0.05). It’s a generally accepted point of court precedents, or maybe in the laws themselves, that you can’t sue for rounding, unless it’s an unreasonable difference from the reality. So if you want to sue AMD, expect to be laughed out of court.
shaolin81 - Friday, November 15, 2019 - linkProblem most probably relies on using High performance profile. When I use it with my 2700X, idle cores are nearly never parked and therefore there's no room for CPU to get Max Turbo on a single core. When I change it to balanced profile, I most idle cores are parked and I get beyon Max Turbo easily - to 4450Mhz. Anandtech should try this.
prophet001 - Friday, November 15, 2019 - linkI think that's me too nathanddrews. I mostly play WoW and though I haven't seen any actual benchmarks, I'm pretty sure that the 9900KS will outperform the Ryzens. WoW just scales with clock speed past like 4 cores.
SRB181 - Friday, November 15, 2019 - linkI've often wondered what people are looking for when cpu's get to this point. I'm absolutely positive the 9900ks will outperform my current CPU (1950x), but I'm getting 78 fps at 4k60 in WOW set to ultra (10) in the graphics. Not being a jerk, but what exactly do you notice in gameplay with 9900ks that I would notice/see?
prophet001 - Monday, November 18, 2019 - linkI don't have a 9900 I've just seen how WoW behaves with various processors and my own personal experience. I have an old extreme processor x299 chipset with a 1080 GTX. It's highly CPU bound. Even though the processor is 4 core hyper threaded, it won't get past like 45 FPS in Boralus. I know it's not GPU bound because I look at the GPU load in GPU-z and it's like 40% load. I can turn render scale up or down and doesn't really make a difference on my computer.
That, along with other people's research, leads me to believe that WoW is highly CPU bound but more specifically, core clock speed bound. People that get 5GHz get much more out of the game than people that leave their CPUs at stock clocks.
Qasar - Monday, November 18, 2019 - linkprophet001 there must be something else going on with your system, as i type this i am sitting in Boralus harbor, right above where the ship from SW docks looking out towards the mountain, with the ship from SW coming into dock on the left. i am getting a minimum of 65 FPS as i spin in the spot. im running a Asus stix, 1060 gaming, with a i7 5930K @ 4.2 ghz. @ 1080P in other zones, i have seen as high as the 180s.... cpu and GPU utilization is 30-40% and a solid 25% respectfully.
maybe there is something else with your system that is causing this ?
Qasar - Monday, November 18, 2019 - linkshould also mention, thats with pretty much max on the graphics options.
WaltC - Friday, November 15, 2019 - linkWrong answer...;) AMD has only ever said "Max single core boost", emphasis on the word "max," which evidently must be translated for the benefit of people mindlessly trying to pick it apart because the meaning of "max" ever eludes them!...;) Really, I've seen all kinds of stupid come out on this one. AMD does not say, "guaranteed single core boost of 4.7GHz" because it's not guaranteed at all--it is the "max" single-core boost obtainable--not the "only" single-core boost the CPU is capable of! Uh--I mean, I'm embarrassed I actually have to explain this, but *any single-core boost clock above the base clock of the cpu* is a *genuine boost of the core* and "max" of course means only the very maximum single core boost clock obtainable at any given time, depending on all of the attendant conditions! So, take a situation in which all the cores boost to 4.5Ghz, 4.6GHz or 4.3Ghz--every single one of them is providing the advertised single-core boost! And yes, people are indeed seeing 4.7GHz *maximums*--but not all of the time, of course, since "max" doesn't mean "all of the time every time," does it,? In their zeal to defend an otherwise indefendable Intel--people have completely butchered the "max" single core boost concept (well, Intel people have butchered it, I should say..;)). Gee--if the only boost these CPUs ever did was 4.7GHz, then none of them would be "max," would they--they'd be the *normal clock* and the damn CPU would be running at 4.7GHz continuously on all cores!...;) I mean, is it possible for people to wax anymore stupid on this subject than this? "Max" absolutely does not mean "all the time every time"--else "max" would have no meaning at all. Jeez--the stupid is strong @ Intel these days...;) Also, it's interesting to note that with fewer cores and a slower clock AMD processes data *faster* than Intel even though the Intel CPU has more cores and a higher clock--so please, the confusion over "max single core boost clocks" from AMD is just plain dumb, imo. It's plain enough--always has been. Multicore CPUs do not exist merely to see to what GHz a *single core* might reach @ maximum! Jeez--we graduated from single-thread thinking long years ago...;) (Or, rather, some of us did.)
