Value for money
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 | 450 MHz | 400 MHz |
| Number of transistors | 278 million | 302 million |
| Manufacturing process technology | 90 nm | 110 nm |
| Thermal design power (TDP) | 48 Watt | 65 Watt |
| Texture fill rate | 10.80 | 8.000 |
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 1.0 x16 | PCIe 1.0 x16 |
| Length | no data | 226 mm |
| Width | 1-slot | 1-slot |
| Supplementary power connectors | 1x 6-pin | 1x 6-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 | GDDR3 | GDDR3 |
| Maximum RAM amount | 256 MB | 256 MB |
| Memory bus width | 256 Bit | 256 Bit |
| Memory clock speed | 1320 MHz | 1000 MHz |
| Memory bandwidth | 42.24 GB/s | 32 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 |
API support
APIs supported, including particular versions of those APIs.
| DirectX | 9.0c (9_3) | 9.0c (9_3) |
| Shader Model | 3.0 | 3.0 |
| OpenGL | 2.1 | 2.1 |
| OpenCL | N/A | N/A |
| Vulkan | N/A | N/A |
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%
GeForce 7900 GT outperforms GeForce 7800 GT by 6% in Passmark.
Gaming performance
Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.
