Microsoft’s DirectStorage 1.1 software programming interface is obtainable for Home windows-based computer systems, the newest graphics playing cards, and superior NVMe solid-state drives. So, it is time to discover out which {hardware} handles one among DirectStorage 1.1’s most enjoyable options, GPU unlocking greatest. Fortuitously, unified has developed an acceptable comparability, whereas PC Gaming Hardware used it to disclose some fascinating findings.
Microsoft’s Direct Storage 1.1 has just a few crucial performance-boosting options, however the primary targets of this API are to cut back CPU load when coping with NVMe requests. It additionally saves invaluable CPU cycles for different workloads and removes sport asset compression through extremely parallel GPUs with little OS intervention and low CPU utilization. As well as, using DirectStorage asset compression and decompression algorithms permits extra information to be transferred than the capability of the storage media (eg SSD), which enormously reduces load occasions.
In the meantime, as a result of GPU {hardware} dealt with DirectStorage unlocking algorithms in a different way, PCGH determined to determine which was which. latest GPUs — AMD’s Radeon RX 7900 XT, Intel’s Arc A770, or Nvidia’s GeForce RTX 4080 — are higher for compressing belongings. They acquired the Compusemble quality testing and ran it on graphics playing cards and Intel’s Core i9-12900K CPU.
| Row 0 – Cell 0 | PCIe 4.0 x4 (7.9GB/s) | PCIe 3.0 x4 (3.9GB/s) | SATA (0.6GB/s) |
| Radeon RX 7900XT | 14.6GB/s | 12.6GB/s | 1.47GB/s |
| Ark A770 16GB | 16.8GB/s | 13.9GB/s | 1.64GB/s |
| GeForce RTX 4080 | 15.3GB/s | 12.7GB/s | 1.47GB/s |
| Core i9-12900K @ 5.20 GHz | 5.2GB/s | 5.2GB/s | 1.47GB/s |
The very first thing that catches your eye is that each one GPUs deal with decompression at the least 2.4x higher than the Core i9-12900K processor. In the meantime, Intel’s Arc A770 is noticeably higher than AMD’s Radeon RX 7900 XT and Nvidia’s GeForce RTX 4080 in the case of GPU asset compression. Within the best-case state of affairs, the A770 can switch/decompress belongings at 16.8GB/s, whereas the RX 7900 XT is third with 14.6GB/s (13% behind the chief).
Precise load occasions are lowered by an order of magnitude from 5 seconds to 0.5 seconds primarily based on PCGH, whether or not AMD, Intel or Nvidia GPU are used. So it would not actually matter which GPU is used, given how shut the decompression charge outcomes of GPUs are — it is all activity dependent and normally adequate to considerably enhance the gaming expertise.
