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 | 6144 | 3840 |
| Core clock speed | no data | 2075 MHz |
| Boost clock speed | 1560 MHz | 2320 MHz |
| Number of transistors | 17,400 million | 26,800 million |
| Manufacturing process technology | 8 nm | 7 nm |
| Thermal design power (TDP) | 140 Watt | 250 Watt |
| Texture fill rate | 299.5 | 556.8 |
Compatibility, dimensions and requirements
Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).
| Interface | PCIe 4.0 x16 | PCIe 4.0 x16 |
| Length | 241 mm | 267 mm |
| Width | 1-slot | 2-slot |
| Supplementary power connectors | 1x 6-pin | 1x 6-pin + 1x 8-pin |
Memory
Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM.
| Memory type | GDDR6 | GDDR6 |
| Maximum RAM amount | 16 GB | 32 GB |
| Memory bus width | 256 Bit | 256 Bit |
| Memory clock speed | 14 GB/s | 16000 MHz |
| Memory bandwidth | 448.0 GB/s | 512.0 GB/s |
| Shared memory | no data | - |
Video outputs and ports
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 | 4x DisplayPort | 6x mini-DisplayPort |
API support
APIs supported, including particular versions of those APIs.
| DirectX | 12 Ultimate (12_2) | 12 Ultimate (12_2) |
| Shader Model | 6.6 | 6.5 |

Benchmark performance
Non-gaming benchmark performance comparison. Note that overall benchmark performance is measured in points in 0-100 range.
Overall score
This is our combined benchmark performance rating. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
- Passmark
Passmark
This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various 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.
Benchmark coverage: 25%
Radeon Pro W6800 outperforms RTX A4000 by 1% in Passmark.
