The latest series of Ryzen CPUs has been out for six weeks and yet only about a week ago were we able to get our hands on the Ryzen 7 X for the first time. The delay had us receiving numerous comments asking us to review it and comparing it to the X, X andall of which we've reviewed by now.
Apparently it's all about binning and yields that may not be as good as AMD hoped, or maybe demand has also played a role. Silicon Lottery recently released some Ryzen binning data and this suggests the better quality silicon has been reserved for the X.
Also, all X processors passed the test at 4. For more casual overclockers like us the difference will likely be even smaller. This is the same frequency limit for the retail X we got.
Needless to say they all deliver a similar gaming experience in this title. However that frequency boost will come with an increase in voltage and this is likely why the X was a little more power hungry than you might have expected. As a result of that increased power consumption the X runs around 3 degrees hotter with the box cooler and 4 degrees hotter with the Corsair Hi Pro.
Power consumption sees the X suck down quite a bit more power than the X, at least relative to the extra performance it offers. As it turns out, not a lot. During heavy workloads the X clocks between - MHz higher, which amounts to a 2.
The X which is clocked MHz higher for the base, may not be able to maintain 3. The confusion creeps in when AMD skips their 95 watt rating for watts with the X. We accept that the X might not be able to sustain 3.AMD Ryzen 7 3700x Temperature Stock Cooler
If an OEM puts a 65w cooler on a 95w part and some buyer says "I'm not hitting 3. Buying advise in short: we highly recommend avoiding the X and instead grab the X. If you find it necessary, upgrade the box cooler with the money saved. The Ryzen 5 remains king of value bar none, and the X offers more cores for productivity, gaming may not benefit as we observed in our GPU scaling benchmark.

AMD Ryzen 7 3800X vs. 3700X: What's the Difference?
Precision Boost 2 without asking the user to tinker or risk their warranty. Why would we do that? It is not our intent to leave anything on the table. It seems even AMD has its doubts about the overclocking proficiency of Zen 2.
Yet we initially had high hopes for the Ryzen 7 X when it first graced our test bench. Read more: These are the best gaming monitors around. Precision Boost 2 increases and decreases clock speed in a scalar fashion as CPU threads are shifted task to task.
Precision Boost Overdrive removes these limits and replaces them with the maximum values your particular motherboard is capable of. Probably fine. We started out with, what we initially believed to be, a generous 1. Black screen. Okay, 1. Following that same stepping we went all the way up to 1. You stop caring after a while.
No luck at Nor But, we finally struck a healthy balance with a x43 multiplier — or 4. Just a little below that red line. And single-threaded applications suffered due to the lack of the occasional boost beyond 4. So while some multi-threaded applications made marginal use of this all-core clock, few games or synthetic benchmarks showed any improvement whatsoever.
The X remained stable at 4.On hand today we have the Ryzen 9 X and Ryzen 7 X, with more content to come in the next few days. It runs at a base frequency of 3. This means Intel will have a slight performance advantage, but keep in mind that the cost of the cooler will be factored into our value analysis for each processor.
We'll also provide some X and X performance figures using an all-in-one liquid cooler. The Ryzen 7 X was equally impressive. These new 3rd-gen Ryzen parts are already looking like kings of productivity. The X also did well hitting points and that placed it roughly on par with the K, so this is a massive performance improvement for Ryzen.
Overall a remarkable performance uplift over the 2nd-gen parts. King of productivity right there. Then when it comes to decompression work, 3rd-gen Ryzen still enjoys a handy performance advantage.
Making these results more impressive is that Premiere is a very pro-Intel piece of software. Next up we have V-ray 1. Using the older build the X took 48 seconds to complete the workload while the X took 68 seconds.

This meant the X was slightly slower than the K but much faster than the K. Meanwhile the X beat everything including the X. We see similar margins in the newer version, though here the Core iX manages to edge ahead of the X.
Once again we see similar margins between the tested processors, though this time the X is much closer to the K than it is to the X. Well, would you look at that. The R7 X consumed less power than the previous-gen and even less than the Core iK. In fact it was comparable to the Ryzen 5 and along with the old quad-core K.
Just as remarkable is the X which is comparable to the X and X, making it worlds more efficient than the K and X. This is an stellar result for AMD and on that high note lets cautiously move into the gaming benchmarks. Battlefield V sees 3rd-gen Ryzen parts trailing Intel's Core i9s again. The X did better relative to the K, but again gaming looks solid on Intel's side. Bumping the resolution up to p reduces the margins significantly.
We were hoping these 3rd-gen Ryzen processors would be a little more punchy in The Division 2. Far Cry New Dawn has always been troublesome for Ryzen processors.
Not a big difference though and as you might expect the gaming experience was identical. DDR is the fastest spec memory AMD recommends using with 3rd-gen Ryzen as higher clocked memory will actually reduce performance, at least when clocked higher than as this changes the Infinity Fabric to a mode rather than Basically sees the Infinity Fabric clocked at a quarter of the memory speed, while is half. This is something we'll follow up on at a later time but for now we can see key performance metrics are not greatly altered by the RAM choice or by not maximizing Ryzen's capabilities on this regard.
As claimed by AMD the PBO feature of the 3rd-gen Ryzen processors can be enabled on all motherboards that support these new processors. A quick look at gaming performance with World War Z we see no major performance difference on both boards.
At a later time we'll check out how this looks for B and X motherboards as well. However, as was the case with 2nd-gen Ryzen, the simple multiplier OC method that we used for the 4.
Here we see when looking at the single core results, it does reduce performance, leaving PBO overclocking as the most effective method overall. On an even more disappointing note, we somehow managed to end the life of our X sample at this stage of the review.Discussion in ' CPUs ' started by theoneJul 14, Log in or Sign up.
My temps are idling in the 60vs, although they don't seem to change much. I couldn't put new paste on as I don't have any only using what was on the cooler. Do you guys think it's purely that, when I first put it on the temps were mid 50's.
Using the Ryzen master software, the temps keep bouncing all over the place, although i don't know if that just lists the hottest core? Jul 14, at AM 2. The idle temps are high across the board atm. With agredsive boosting and high voltage on single and duel core boosting keeping the temps higher at idle. On my custom loop system my idle temps are mid 50s all core boost low 60s bios revisions and software tweeks to agreeive boosting will help keep the temps down in the future Although if you have reseated the cooler a few times I would highly recommend getting some heat past though.
Jul 14, at AM 3. Jul 14, at AM 4. Yea, this was all last night and also a bit of squeaky bum time. Just done some benches and im ranging from 38 upto 76 degrees with the fan on high. Jul 14, at AM 5. I have just built a X system Idle seems to range anywhere from degrees.
Played PUBG for a while on it last night and was sat at around 70ish degrees. Using the stock cooler too which i have taken off and reapplied paste too which doesn't seem to have made any difference. Jul 14, at AM 6. Are you using XMP? I find it idles higher and bounces round a lot more with it on.

Ryzen 7 3700x high voltage and temps (tried everything)
Yeah temps are constantly moving. Using the stock heatsini currently but used kyronaut to replace stock tim mine may go from lows 40s upto 70s on the ryzen balanced power option.Did I mess up with putting on the stock cooler? Is this normal for the x or did I mess up and should I clean and reapply thermal paste? According to the link below, see if it idles cooler using only CPU-Z. Thanks for the responses! Could just be some updates but I would not know for sure. I checked it this morning, it seemed to be idling in the high 40s which is a significant improvement IMO.
That high voltage is reported also by Ryzen master 1. I might have to look into undervolting and just trying to get stock performance 4. Honestly, its the noise that bothers me so much. As lame as it sounds the only reason I havent bought a new one is because I want to keep the RGB hahaha. I remember Jayz2Cents saying that his board came with similar voltages default, and that those where way overkill even for Overclocking.
Maybe drop those voltages a bit? Thanks for that video!! I think that is the problem. Edit: Mobo was dead on arrival Should have replacement here today. Your cpu core temp is really high, like mine was with my x. I had to manually lower the voltage to 1. Except I tried 3 different coolers, and 2 motherboards with the same idles and load temps. I saw the JayzTwoCents video and tried setting the voltages to what he recommended and all it did was lower my performance.
I was getting about degrees just sitting doing nothing. My room is about 72 and have ample case fans.Forums New posts Search forums. New posts New posts New profile posts Latest activity.

This drew our attention, because we already knew that our X could barely manage 4. Our initial experience with Ryzen 2 led us to believe that a volt-frequency curve would look almost exponential, like the one on the screen now. That was our hypothesis. To be clear, we can push frequency higher with reference clock increases to or MHz and can then sustain 4. Our goal is to plot a volt-frequency curve with just multiplier and voltage modifications. We typically run out of thermal headroom before we run out of safe voltage headroom, but if voltage increases exponentially, that will quickly become a problem.
That kind of change suggests an exponential increase, and we wanted to know more. We decided to measure and plot the volt-frequency curves of both chips with frequency on the X axis and minimum stable voltage on the Y axis.
At increasing frequencies, the required voltage for both chips rapidly increases out of a safe range, and the vertical difference between the lines on our theoretical graph at a given frequency becomes huge 1.
However, at a given voltage the horizontal difference remains tiny 4GHz vs 4. Based on this knowledge, this was what we expected to see:. Our previous test used both Prime and Blender, but in the interest of efficiency in these tests we tested stability by running our most stressful Blender benchmark for about ten minutes. BIOS settings and hardware were kept the same other than CPU, vcore, and all-core multiplier, which were the variables being tested.
Ours can do 4. All-core overclocking the X without LN2 is pretty pointless in terms of performance anyway--check our review for details. At the low-end, we were able to maintain a minimum stable voltage of 1. Increasing by MHz, to 3. The next MHz jump required 0.
Our final step to 4. We already knew our would do 4GHz at a bit over 1. At the high end, it needed much more, to the extent that at 4. We knew our X was capable of more, so we pushed past 4. The X required an increase in voltage to 0. We switched to a larger cooler at this point, as we were hitting 70 degrees and up on Tdie, which was causing instability and crashes in our Blender test.
You can see that the curve gets incredibly steep at 4. Ignoring the extra-well-cooled results for the X, the plotted curves are almost what we predicted, albeit less dramatic within the limited bounds of our test. Reformatted to match our graphs, his data looks like this:.
His voltages are lower because, among other reasons, he was using a higher level of LLC, but the shape of the curve is close to our own, right down to the sharp increase in required voltage at the end: he went as high as 1. He was testing in increments of. This was an academic experiment. Again, we could push higher frequencies with lower voltages if we were to tune, say, the reference clock. The point is to control variables as much as possible, then just research V-F scaling between the R7 and R7 X.
