DDR4 Round-Up: Corsair, G.SKILL, Kingston, PNY, Predator Tested

Compute and Productivity Tests

For 7-Zip compression workloads, G.SKILL’s ultra-tight 3600MHz dual-rank kit rules the roost on our AMD test platform. It’s tight at the top, though, with the slightly looser Predator and Kingston 2x16GB kits also fairing very well. Slack timings for a 3600MHz clock speed demote the Corsair set a little behind the rest of the 3.6GHz dual-rank pack.

Propping up the chart are the single-rank 16GB sets. Even higher RAM frequencies and/or enhanced Infinity Fabric clock speeds cannot offset the benefit of dual-rank module performance on the AMD test platform in this benchmark. Interestingly, Kingston’s uber-fast Renegade set running at 4600MHz did not seem to take too kindly to this benchmark, as was shown by higher performance from the more sensibly clocked PNY kit.

Decompression margins are clearly tighter, and this time frequency does play a role in rankings as shown by the strong performance from the Kingston set running at 4.6GHz DRAM frequency.

G.SKILL still tops the chart here thanks to tight timings and the preferential 3600MHz clock for the AMD platform. And we still see the sensibly-clocked, single-rank kit from PNY propping up the table, despite one configuration running with a 1900MHz FCLK.

There really is not much to tell apart these kits in Blender. That is due to the sheer level of focus put on the CPU in this tile-based rendering workload.

PNY’s single-rank kit with less preferential memory controller clocks for the AMD CPU bottoms the chart by a tiny margin. But the rest of the kits are practically the same for our test run.

Cinebench paints a similar picture, which is unsurprising given that it is also a tile-based rendering piece of software. There is very little difference between the performance of the 3600MHz dual-rank kits, though G.SKILL does fall back a little for some reason.

Kingston’s uber-clocked Renegade kit once again puts in a good performance show here. And we continue to see the 4000MHz PNY set at the bottom of the chart when its CPU-tied Memory controller clock is not optimised.
