Cyberpower Ultra 9 XT (5900X/6800XT) Review

Here we see Cinebench R15 results for both multicore and single core tests along with the results after one run compared to four runs, and as you can see there’s hardly any change at all after multiple runs, which is excellent!

Cinebench R20 results are compared with the PCSpecialist system and as you can see the Cyberpower’s 5900X really wiped the floor with the i7-10700K’s multicore results, though we would expect this given its increase core count. Even the single-core performance pulls into a steady lead though.

Time taken to render our BMW CPU test within Blender 2.93 was 120 seconds, which is very quick and what we’d want to see from our 12-core 5900X. PC Mark 10 shows how well the system performs at a variety of tasks, with a particularly excellent result in the digital content creation benchmark.

Looking at our memory benchmarks also shows our system take a strong win against the PCSpecialist system, but again we have double the RAM that also runs at higher frequencies.

CrystalDiskMark results are what we were expected, but they are also slightly disappointing… and here's what we mean. The 500GB Seagate Firecuda 520 drive is rated for 2500MB/s writes but the 1TB and 2TB models are rated for 4400MB/s writes. Our drive is rated at a 5,000MB/s read, which we pretty much achieve here and while we scored 2,527MB/s write, which is just above the official rated speed, we still feel it’s a bit on the slow side for 2021 standards. There are drives available now, using Phison's latest E18 controller, that can deliver in excess of 6000 MB/s writes, so we’d have loved to see something faster here.
