Connectivity and outputs
Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
| Display Connectors | No outputs | No outputs |

Synthetic benchmark performance
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.
Gaming performance
Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.
Pros & cons summary
| Performance score | 11.50 | 22.04 |
| Recency | 5 January 2013 | 21 March 2023 |
| Maximum RAM amount | 5 GB | 24 GB |
| Chip lithography | 28 nm | 5 nm |
| Power consumption (TDP) | 225 Watt | 72 Watt |
L4 has a 91.7% higher aggregate performance score, an age advantage of 10 years, a 380% higher maximum VRAM amount, a 460% more advanced lithography process, and 212.5% lower power consumption.
The L4 is our recommended choice as it beats the Tesla K20m in performance tests.
