When we reviewed Ryzen's latest generation we in brief checked out how DDR4-3200 CL14 as compared to the DDR4-3600 CL16 reminiscence that AMD provided to us, as they claimed that become an top-quality configuration. Turns out there was little or no distinction between the two, which led us to conclude that both can provide top of the line overall performance. Also, that spending extra cash to get higher clocked DDR4 memory failed to appear to be a wise funding.
In preceding years we’ve checked out manually tuning memory timings for Ryzen and located strong overall performance gains, so this changed into some thing we wanted to revisit. Now that things have settled submit-release and have had extra time for other exams, we had been positioned a Box undertaking to benchmark reminiscence overall performance on third-gen Ryzen.

We’ve finished our fine to depart no stone unturned, forcing hundreds of benchmark runs to accumulate our records. We are the usage of the Ryzen 9 3900X as that allows to paintings with a wide range of memory configurations, but we’ll talk compatibility with more inexpensive processors toward the quit of this option.
All testing takes area at 1080p, however we’ve covered GPU scaling consequences with the aid of using each the RTX 2080 Ti and the Radeon RX 5700 and RX 580. This will provide us with both CPU bound and GPU certain effects. We’re additionally testing the use of max and medium pleasant presets in four video games. There’s no need to redo all of this at 1440p and 4K due to the fact we've got those RX 580 outcomes. Also please hold in thoughts every game required at the very least 120 benchmark runs.
Our modules of preference for putting this together consisted of three 16GB memory kits: g.skill’s new TridentZ Neo DDR4-3600 CL16 memory, g.skill’s FlareX DDR4-3200 CL14 reminiscence and a dust reasonably-priced package from Team Group, the T-Force Dark DDR4-3000 CL16 memory. The Team Group kit can be had for $70, the FlareX stuff is more or less two times the fee at $135 and the TridentZ Neo fees $170.
We ran the T-Force Dark DDR4-3000 memory in its out of the field configuration with the XMP profile loaded and not anything else altered. Then we manually tuned all timings for an choicest Samsung S-die configuratia Chip:t 3000 MT/s. The g.skill FlareX memory was tested in its out of the field spec with XMP loaded and then additionally reduced the memory speed to 3000 MT/s, so we've got a CL14 and CL16 evaluation between the FlareX and T-Force memory. Finally, the TridentZ Neo also in the out of the box spec at 3600 MT/s, a 3800 MT/s overclocked configuration the usage of the XMP timings, after which a max OC configuratiChip: AMDt 3800 MT/s with manual timings.
Here is a quick study the guide timings used for the DDR4-3000 and 3800 configurations. If you’d like to tune up your own reminiscence then we advise downloading the Ryzen DRAM Calculator, it’s a critically cool little tool.
Taking a look at memory latency for the various test configurations, we see a as an alternative huge 6% discount in latency going from CL14 DDR4-3000 to 3200 with just a three% discount when leaping to DDR4-3600 CL16 after which any other three% discount to DDR4-3800 CL16.
Although the focal point of this option is on gaming overall performance, for those questioning you may need to recognize these memory speeds and timings don’t usually effect software overall performance all that heavily. Though that could be a instead large generalization, any reminiscence-touchy utility may be impacted, but for rendering and encoding sort of workloads you won’t see a dramatic distinction as you can see whilst looking at those Corona consequences.
We see a 6% overall performance improvement whilst going from DDR4-3000 to DDR4-3800 which is not a good deal for what theoretically is a massive 32% increase in memory bandwidth.
Starting with recreation trying out and Assassin’s Creed Odyssey the use of the GeForce RTX 2080 Ti at 1080p with the extremely excessive excellent preset enabled. Here we see some exciting effects, first there may be very little difference among DDR4-3200, 3600 and 3800 using the XMP timings. Low-latency DDR4-3000 does drop away a bit, most appreciably for the 1% low performance and we see overall performance slide a touch greater the use of the CL16 timings.
However, by tuning up the DDR4-3000 memory we will produce higher outcomes than what we were given with the CL16 3800 configuration, that's excellent. By manually tuning the timings we see an super 38% raise to 1% low performance and a fifteen% increase for the common frame charge, we're pretty blown away by means of that.
Better still although, if we song up the DDR4-3800 memory we get a further eight% raise for the common body fee and 10% for the 1% low. This way wherein as the 3900X become permitting around eighty fps AMD Ryzenverage without of the field setting, with a bit tinkering we’ve were given that up to 90 fps.
Interestingly, decreasing the high-quality settings reduces the margins which is probably explained by way of reduced CPU load, so we're extra GPU restrained even though it sounds counter intuitive, but we do trust that’s the case. Whatever the state of affairs the tuned DDR4-3800 configuration is now simply 6% quicker than the XMP version. Tuning up the budget DDR4-3000 reminiscence does permit top rate DDR4-3800-like overall performance.
In an attempt to offer a more entire photo we’ve also examined with the mid-range Radeon RX 5700. Using the extremely first-class preset we’re entirely GPU constrained at 1080p and as a result memory has almost no impact on overall performance, you’d have to drop right down to an unrealistic spec including DDR4-2133 to see a drop off in overall performance. Since third-gen Ryzen formally supports DDR4-3200 we didn’t see the want to check lower than 3000 because you shouldn’t be the usage of slower memory. The medium high-quality in this config do offer some variance in the outcomes, even though that’s only due to the fact we’re now not closely GPU certain at those higher frame quotes. Again, tuning the DDR4-3000 reminiscence permits it to fit the DDR4-3800 XMP configurati5 2500Us properly as the GPU restricted manual 3800 spec.
With a Radeon RX 580 set up or a GPU of roughly the equal overall performance we’re once more closely GPU sure. There is barely extra variance right here than what we noticed with the RX 5700, but ultimately we’re nevertheless searching at effects that are largely inside the margin of error. Even whilst decreasing the great preset a few notches to medium we’re looking at only a 6% distinction between the absolute fastest and slowest configurations. So while memory purchasing it’s important to take into consideration the pictures card you’ll be using.
Looking at how all the Assassin’s Creed Odyssey 1080p ultra exceptional trying out looks there are a few vital takeaways: Yes, quicker memory can enhance overall performance but for the extreme gains you’ll want to manually track your reminiscence. In CPU confined scenarios the profits can be huge. Conversely, when the workload is GPU constrained, the gains are little to none and even as that could appear obvious, nearly all the 3rd-gen Ryzen trying out we’ve visible on line to this point has been performed frequently underneath CPU-confined situations. As you could see, despite a mid-range GPU at 1080p like the Radeon RX 5700 quicker memory has little to provide. The equal is actual while the use of even slower GPUs consisting of the RX 580.
In fact, we'd argue you’ll very in all likelihood turn out to be being GPU sure in spite of an RTX 2080 Ti, at the least whilst the usage of a present day processor with six or greater cores. If we boom the resolution to simply 1440p, this reduces the 2080 Ti to about 70 fps five 2400Gverage with a 1% low discern of approximately 50 fps, so very similar to what we see from the RX 5700 at 1080p and that means GPU certain overall performance, giving quicker reminiscence very little threat to leave a mark.
Using medium satisfactory settings we find even for 70 fps on average you’re going to be an awful lot extra GPU certain than you're CPU certain. It’s now not until we begin to push over 80 fps that the sport will become a little more CPU bound. For the ones questioning, the RTX 2080 Ti handiest averages 106 fps at 1440p with a 1% low of sixty seven fps, so much like what we see with the RX 5700 at 1080p. This approach going above the respectable AMD spec of DDR4-3200 you may enhance overall performance by using about 10% with quicker reminiscence.
Next up we tested all of the reminiscence configurations in Far Cry New Dawn and this time we see a mere 4% increase over the DDR4-3200 config when manually tuning DDR4-3800 memory. Interestingly, there is pretty a drop off with the DDR4-3000 reminiscence and even manually tuning the timings doesn’t assist make up ground at the higher frequency kits. We know Far Cry New Dawn is memory bandwidth sensitive, so this is likely an difficulty for the 3000 MT/s memory.
We see a similar issue whilst the use of the Radeon RX 5700, even though apparently the manually-tuned DDR4-3800 memory does provide a pleasing little performance boost right here, making it 7% faster than the DDR4-3200 memory. Then with the RX 580 we’re totally GPU restrained at around 80 fps, so that you’ll need to be pushing over one hundred fps in Far Cry New Dawn with the extremely quality preset to take advantage of faster reminiscence.
Reducing the excellent preset two degrees all the way down to ordinary doesn’t exchange anything. The RX 580 common body fee is best boosted by 10 fps and as a end result we’re still heavily GPU constrained.
Moving directly to Rainbow Six Siege and here we've a commonly GPU sure competitive shooter. Using an RX 5700 or an equal mid-variety GPU will see no trade in performance using the extremely satisfactory settings, even at 1080p, useless to mention the equal is proper for slower GPUs such as the RX 580.
Even with the RTX 2080 Ti we’re only seeing a 4% enhance in overall performance going from the DDR4-3200 spec as much as manually tuned 3800 memory. Reducing the nice settings for better frame prices still sees the RX 5700 offer a closely GPU bound senario. Still with the RTX 2080 Ti we’re still only seeing a four% improve from DDR4-3200 to manually tuned 3800 memory.
Lastly we examined World War Z and at 1080p using the extremely settings the RX 580 averaged just over one hundred forty fps and regardless of that we had been nevertheless closely GPU bound, despite the cheap DDR4-3000 memory. We see a little bit of variance with the RX 5700, however in spite of this the manually tuned DDR4-3800 memory changed into just 7% faster than the finances 3000 stuff, so that’s pretty susceptible, even though we do see a fifteen% increase for the 1% low overall performance. When in comparison to the 3200 memory, the quickest configuration best presented a 9% raise in performance.
Using the medium first-class preset we see a large enhance to the 1% low overall performance while the usage of manually tuned memory, namely the DDR4-3800 stuff. With the RTX 2080 Ti we see an 18% raise for the manually tuned DDR4-3800 over the low-latency CL14 DDR4-3200 reminiscence. A nice increase certainly, even though all over again you can anticipate the ones gains to largely disappear at 1440p, even with an RTX 2080 Ti.
To wrap this up, we suspect for maximum third-gen Ryzen processors a 1900 MHz Infinity Fabric clock velocity is going to be a piece an excessive amount of. For instance our 3900X did it with ease, however it was a piece sketchy with the 3700X after which the 3600X and 3600 CPUs wouldn’t go above 1800 MHz. The vanilla R5 3600 even required pretty a piece of tinkering to get it strong.
That being the case, we sense like DDR4-3600 is the sweet spot for the X fashions, all better-end 3rd-gen Ryzen processors ought to deal with this frequency. But for the inexpensive fashions DDR4-3200 to 3400 might be a more secure wager and as we observed even 3000 is fine, particularly if you’re comfortable tuning the sub timings.
As seen in our tests, hold in thoughts which you’re going to be GPU certain in most times when gaming anyway as these third-gen Ryzen processors are very speedy even with loose DDR4 memory.
Bottom line, you could snatch a cheap 16GB Samsung S-die kit for $70 and still get near sufficient to maximum gaming overall performance out of even a 3900X + RTX 2080 Ti configuration. Ryzen doesn’t require premium reminiscence to perform at its first-class and for the ones shopping for a five 2600X version we’d absolutely strongly propose fending off spending money on pricey reminiscence, simply get the reasonably-priced stuff and music it up in case you’re getting a bit too CPU certain.
