Let’s finally take a look at the performance, first in the synthetic benchmarks AIDA64 Cache & Memory version 6.32.5600 and Geekbench 3 version 3.4.3. All benchmarks were run three times and then averaged from the results.
The read and write speeds scale almost linearly with the clock rate, which is why there are no big surprises here. Even in Gear 2 with DDR4-3800, the Intel system can still set itself apart from the XMP configuration here. Accordingly, the completely manual setting on the AMD platform cannot yet show its advantage in the timings. The control pattern, like its clock speed, also sorts itself out behind the DDR4-4400 configuration.
Copy and latency tests are known to be relatively closely intertwined, as low latencies allow faster switching between writes and reads, and thus more copying. On the Intel platform, the configuration with DDR4-3800 and Gear 2 is almost 5 ns behind its peers on the same platform. This nicely shows the uncanny valley of latency on Rocket Lake between DDR4-3733 and DDR-4000 – you’d rather stay either below and in Gear 1 or above in the Gear 2.
The B-Die kit can score points in latency with its naturally tight timings, but loses out to the DDR4-4400 configuration significantly in copy due to the clock speed and loose remaining timings. On the AMD platform, the improvements from one setting to the next are relatively small, but steady. With the manual DDR4-3800 1:1 setting, even the Gear 2 latency of the 11700K can be caught up with at the same clock speed.
Geekbench 3 is known to be a good all-round benchmark and relatively reliable indicator for performance in real-world applications. Lower latencies and higher clock rates contribute almost equally to the result here and thus carry the DDR4-4400 setting almost to the 10000 point mark. Rocket Lake is truly a rocket booster for RAM performance. On the AMD platform, the Talos kit with manual timings can even outperform the B-Die control kit.
