Samsung 990 Pro 2TB Review

We used CrystalDiskMark 8‘s custom settings to test the 4K random read 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.

Using our 4-threaded random read 4K tests we couldn't get close to the official maximum at QD32 of 1,550,000 IOPS. The best figure we saw was 356,356 IOPS at QD16.

4K Random Read v QD Performance compared.

Even though we couldn't get close to the official maximum speeds, the drive is the fastest we've seen to date at QD2. However, as the queue depth deepens the performance drops away.

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.
