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.
| Core clock speed | 650 MHz | 550 MHz |
| Number of transistors | 278 million | 278 million |
| Manufacturing process technology | 90 nm | 90 nm |
| Power consumption (TDP) | 84 Watt | 65 Watt |
| Texture fill rate | 15.60 | 13.20 |
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).
| Interface | PCIe 1.0 x16 | PCIe 1.0 x16 |
| Width | 1-slot | 1-slot |
| Supplementary power connectors | 1x 6-pin | 1x 6-pin |
Memory
Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated VRAM and use a shared part of system RAM.
| Memory type | GDDR3 | GDDR3 |
| Maximum RAM amount | 512 MB | 512 MB |
| Memory bus width | 256 Bit | 256 Bit |
| Memory clock speed | 1600 MHz | 1400 MHz |
| Memory bandwidth | 51.2 GB/s | 44.8 GB/s |
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 | 2x DVI, 1x S-Video | 2x DVI, 1x S-Video |

Synthetic benchmark performance
Non-gaming benchmark performance comparison. The combined score is measured on a 0-100 point scale.
Combined synthetic benchmark score
This is our combined benchmark performance score. 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.
7900 GTX outperforms 7950 GT by 13% in our combined benchmark results.
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: 24%
7900 GTX outperforms 7950 GT by 13% in Passmark.
Gaming performance
Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.
Advantages and disadvantages
| Performance rating | 0.98 | 0.87 |
| Recency | 9 March 2006 | 6 August 2006 |
| Memory bandwidth | 51.2 | 44.8 |
| Power consumption (TDP) | 84 Watt | 65 Watt |
Judging by the results of synthetic and gaming tests, we recommend GeForce 7900 GTX since it shows better performance.
