Connectivity and outputs
This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.

Synthetic benchmarks
Non-gaming benchmark results comparison. The combined score is measured on a 0-100 point scale.
Combined synthetic benchmark score
This is our combined benchmark score.
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
| Performance score | 20.23 | 19.18 |
| Recency | 25 February 2021 | 19 January 2022 |
| Maximum RAM amount | 8 GB | 4 GB |
| Chip lithography | 12 nm | 6 nm |
| Power consumption (TDP) | 185 Watt | 50 Watt |
CMP 40HX has a 5.5% higher aggregate performance score, and a 100% higher maximum VRAM amount.
Pro W6400, on the other hand, has an age advantage of 10 months, a 100% more advanced lithography process, and 270% lower power consumption.
Given the minimal performance differences, no clear winner can be declared between CMP 40HX and Radeon Pro W6400.
