Samsung 990 Pro 2TB Review

We used CrystalDiskMark 8‘s custom settings to test the 4K random write performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

The best result we saw from our 4K random write results was 263,972 IOPS at QD16 before the performance dropped back at QD32 at 252,199 IOPS, both of these figures are nowhere near the official maximum.

4K Random Write v QD Performance compared.

At shallower queue depths the drive sits in the top ten in our results chart but as the queue depth deepens the drive drops down the chart, eventually ending up in the bottom ten with the QD32 result of 262,199 IOPS.

KitGuru Games: DLSS 5 misses the point

It would be hard to argue that NVIDIA’s DLSS technologies haven’t been a net positive to the PC space, with the machine-learning based upscaler successfully translating lower resolution inputs into a final image which is perceivably sharper while hogging fewer resources. Though somewhat more contentious, the next evolution of DLSS came in the form of Frame Generation, using ML in order to generate additional frames for high-refresh rate gaming. Both techniques can have their issues, but generally speaking they’ve allowed for more people to experience higher-end titles at increased frame rates. DLSS 5, however, takes a sharp pivot, with a very different end goal in mind than the performance-boosting versions that came before.
