Synthetic benchmarks

As always, we start with the synthetic benchmarks, running each 3 times and keeping the best result. In the case of Linpack Xtreme, 5 loops and their average value are used for each run.

Since Linpack Xtreme is already heavily limited in latency with DDR5, the bandwidth and thus the clock rate is primarily decisive for the result here. Accordingly, the Teamgroup DELTA RGB DDR5-6400 kit is already in the front as the defacto fastest kit in the XMP. The whole thing then gets even faster with higher clock rates, with up to 633 GFlops with DDR5-7000, mind you with only 5.1 GHz on the cores and 4.9 GHz on the CPU’s cache.

In SuperPi 32M, latency is known to be the be-all and end-all, so the DDR4 configuration still has a loud say here and is faster than all DDR5 kits in XMP so far. Only with manual tuning and optimized subtimings can times below 6 minutes also be achieved with DDR5, whereby the minimum of 356 seconds with DDR5-7000 is really impressive.

As is well known, the clock rate is the main factor in the AIDA write and read tests, which in turn is decisive for the data throughput. Here, the DELTA RGB with 6400 Mbps in XMP already exceeds the 100000 MB/s mark, ahead of all other kits. The result can then be increased to almost 115000 MB/s with manual tuning.

The picture is similar in the write test and the Teamgroup kit with its clock advantage is ahead of all other kits.

As expected, this trend continues in the Copy Test, with the Teamgroup modules not being the fastest XMP config due to their higher latency, albeit only by a razor-thin margin.

In the latency test, even the fastest DDR5 XMP kit still has considerable disadvantages compared to DDR5, whereby the Teamgroup DELTA RGB kit still cuts the best figure here. Only with manual tuning can latency values below 50 ns be achieved, which sometimes even undercut DDR4.

Geekbench 3 is known to be the RAM benchmark for once everything with its various subtests that claim both latency and bandwidth. The DELTA modules already achieve almost 11000 points in the multi-core memory score in XMP. With manual tuning at DDR5-7000, the 14000 point mark is left behind, for which we first had to realign our diagram. The performance matches the clock and the DELTA modules deliver, whether in XMP, overclocked with or without active cooling.
