Intel configuration test:
Of course, this kit will only be tested on an Intel platform, as our comparisons have been based on this configuration from the outset. This kit is intended for the Intel platform only. Lexar does not currently offer memory kits supporting AMD’s EXPO profile.

- Processor: Intel i9-12900K Alder Lake and i9-13900KS Rocket Lake for OC
- Memory : 32 GB Lexar ARES RGB 6400 MT/s CL36
- Graphics card: MSI GT 710
- SSD: Western Digital SN850 NVMe SSD M.2
- Power supply: be quiet! Dark Power PRO 12 1500w
- Operating system: Windows 10 64-bit (Z790)
Aida 64 :
This is a software program capable of providing you with a wealth of information about your configuration, but above all it has the special feature of a memory benchmark. This calculates the read, write and copy speeds, as well as the latency, of your memory kit. It is often used to compare memory kits. It’s an excellent tool if you want to compare the performance of your memory kit with those we’ve already tested.
The version used for testing is 6.92.6603 beta, and we’ve taken the performance of previously tested kits.
The performance of this first test seems totally logical to us, with performance close to what we’ve obtained with our other 6400 MT/s CL32 kits. Throughput averages 102,128 MB/s. So, as usual on an Intel platform, you’ll need to prioritize frequency and tight timings to get the best performance.
The same applies to write speeds, which are in line with the average for kits of this frequency, i.e. 88,230 MB/s. The logic of the graph remains identical to the previous one. The Corsair Dominator Platinum 4800 MT/s CL19 in DDR4 achieved 67,251 MB/s. Once again, we note a logical progression between the different frequencies.
The findings are identical in copy, with once again a consistent position within our graph. The Corsair Dominator Platinum 4800 MT/s CL19 in DDR4 achieved a copy speed of 57330 MB/s. As you can see, it’s in reading and copying that DDR5 takes a clear lead over DDR4. Note also the difference between a DDR5 kit at 4800 MT/s (69,419 MB/s) and one at 7400 MT/s (99,993 MT/s). If we hadn’t activated our XMP profile in the BIOS, our kit, sold as a 7200 MT/s model, would really have been clocked at 4800 MT/s.
Finally, latency. This is the value on which all eyes are focused, as DDR5 lags a little behind. Our best DDR4 kit in this respect was the G.SKill Trident Z Royal Elite 4000 MT/S CL14, which achieved 41.4 ns. You’ll notice that the higher the DDR5 frequency, the narrower the gap. Note that a 3200 MT/S CL16 DDR4 kit has a latency of 50.3 ns. Here, it’s 58.1 ns for our Corsair Dominator Titanium 7200 MT/s CL34.
Geekbench 3.4.4:
This benchmark is available in several revisions, version 5 having just been released a few weeks ago. It provides two scores: one single and one multi. Using this benchmark, we’re going to focus on the performance obtained on the ” Memory Multi-Core ” score, which differentiates memory performance.
The version used for testing is 3.4.4.
For the Geekbench 3 benchmark, despite the single-core frequency of our i9-12900K being 5.2 GHz, we note a difference in score between the different memory kits. Once again, the logic of frequencies and timings is respected.
In multi-core, the difference between our kits is smaller. Still for information, in DDR4, our best score was 48,800. Of course, we have to take DDR5 into account, as well as the performance provided by the Alder Lake CPU.
As soon as we isolate the memory score, real differences are visible between kits. Our kit of the day scores 11,072 points! We’ll be keeping a close eye on this score when we start overclocking. It’s a good indicator of the gains made by overclocking.
In DDR4, our best kit scored just 7,748 points. Once again, DDR5 combined with the Alder Lake processor offers a huge advantage.
Geekbench 5.2.5:
We decided to add this extra benchmark, but why? The CPU benchmark uses new tests that more closely simulate the tasks facing processors in the face of the latest applications. Geekbench 5 also increases the memory used in the benchmark to better reflect the impact of this parameter on CPU results. For the time being, we’ll be keeping both, since version 3 is still widely used.
Whereas in Geekbench 3, we had a difference in single core, here in version 5, performance is pretty much identical and our kit of the day scores 2,008 points.
Finally, the last score in our benchmark series with a total of 19,425 points for our Lexar ARES RGB 6400 MT/s CL32 kit. Still to give you a benchmark score in DDR4, our best score was 11,179 points.
Geekbench 6:
We recently received a key for Geekbench version 6. Just enough time to run all our kits through the benchmark again, and we’ll soon be bringing you the performance results obtained with this new software. Our test platform will also be evolving over the coming weeks, with the arrival of new motherboards at the editorial office.
