NVIDIA BETA Driver Delivers Big SSD Performance Boost In DirectStorage 1.2, Gen5 Up To 50% Faster Than Gen4

wccftech.com:

Microsoft's DirectStorage 1.2 API has seen a big boost in SSD performance, both Gen5 & Gen4, with NVIDIA's latest BETA drivers.

Using the DirectStorage GPU Decompression benchmark, Compusemble has published another video that highlights the advantages of using a Gen5 SSD over a Gen4 one and how its actual performance is realized thanks to the last version of the API running on optimized NVIDIA GPU drivers.

The NVIDIA driver in question is the 535.50 BETA which includes some major optimizations for the Microsoft DirectStorage 1.2 API and these optimizations allow for a big boost to SSD performance. The same optimizations will be carried over to a public driver so that everyone can enjoy the SSD performance improvements.

To demonstrate the performance uplift achieved by the new drivers, first, we had a standard test running the older NVIDIA 532.03 Drivers. The drives used were the Crucial T700 Gen5 which is the fastest available consumer SSD yet and the Sabrent Rocket 4 Plus-G, a high-end Gen4 drive that is also specifically optimized for DirectStorage API. The 1.2 API already gives a big boost by moving the copy after GPU decompression to the compute queue. This shows a clear difference between the Gen5 and Gen4 SSDs with the Gen4 maxing out at 22.26 GB/s bandwidth while the Gen5 SSD maxes out at 28.09 GB/s bandwidth.

However, with the new NVIDIA GeForce 535.50 drivers, the Gen5 SSD pushes up to 33.12 GB/s of total bandwidth while the Gen4 SSD caps out around the same 22.80 GB/s of bandwidth that it was previously offering. Not only is the bandwidth
