Technical specs
General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.
| Pipelines / CUDA cores | 768 | 4096 |
| Core clock speed | no data | 2100 MHz |
| Boost clock speed | 2321 MHz | 2400 MHz |
| Number of transistors | 5,400 million | 21,700 million |
| Manufacturing process technology | 6 nm | 6 nm |
| Power consumption (TDP) | 53 Watt | 225 Watt |
| Texture fill rate | 111.4 | 614.4 |
Size and compatibility
Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).
