So, now we finally get to the benchmarks and first to the synthetic tests. All configurations go through the same tests as in our DDR5 tests on Z690, so that we get as representative a picture as possible of the performance in the most diverse scenarios. As always, each benchmark is run 3 times and the best result is used to eliminate any run to run variances as much as possible.
Linpack Xtreme is a compute benchmark that favors a mix of throughput and latency paired with CPU processing power. Here, the RAM speed makes a big difference, but the FCLK clock rate effectively makes none. At the top is the manual Dual-Rank Config with 811.6 GFlops, which is almost 9% more than the standard RAM settings.
The AIDA64 read, write and copy tests are known to be very theoretical indicators that largely depend only on the RAM clock rate. The ranking is similar to the Linpack Xtreme, only with larger distances. The “Aggressive” timing preset can make up almost 8% here compared to the pure EXPO Config and ranks behind the manually optimized configurations. Here, the dual-rank variant with 6400 Mbps and CL32 is the fastest again.
In the AIDA64 latency test, we again see more or less the same ranking, whereby the Infinity Fabric clock or FCLK is still most noticeable here with 2-3% lower access times, whether with JEDEC or EXPO RAM. However, the working memory itself with its timings weighs heavier here as well, so the manually optimized Hynix M-Die configurations with 2133 MHz FCLK are significantly faster than the Samsung B-Die counterpart with 2167 MHz FCLK.
In the Geekbench 3 Multi-Core Memory Test, almost all characteristics of the working memory come into play, clock rate, timings and ranks. And the FCLK also makes itself felt here once again, with pretty much exactly one extra point per MHz – coincidences do happen! The order remains the same again, though, and there is a remarkable 42% between the fastest and slowest RAM configuration. So far, the 2:1 config has flown under the radar. It is always a bit slower than the 1:1 variant, but it is far from being a second-class option anymore, as it was with Zen 3.
