Synthetic benchmark performance
Non-gaming benchmark results comparison. The combined score is measured on a 0-100 point scale.
Passmark
This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
Pros & cons summary
| Recency | 1 September 2020 | 27 August 2008 |
| Maximum RAM amount | 24 GB | 512 MB |
| Chip lithography | 8 nm | 55 nm |
