Detailed specifications
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 | 48 | no data |
| Core clock speed | 166 MHz | 430 MHz |
| Boost clock speed | 1050 MHz | no data |
| Number of transistors | 392 million | 302 million |
| Manufacturing process technology | 22 nm | 110 nm |
| Power consumption (TDP) | 35 Watt | 86 Watt |
| Texture fill rate | 6.300 | 10.32 |
| Floating-point performance | 15.6 gflops | no data |
Form factor & 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 |
| Length | no data | 228 mm |
| Width | IGP | 1-slot |
VRAM capacity and type
Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.
| Memory type | System Shared | GDDR3 |
| Maximum RAM amount | System Shared | 256 MB |
| Memory bus width | System Shared | 256 Bit |
| Memory clock speed | System Shared | 1200 MHz |
| Memory bandwidth | no data | 38.4 GB/s |
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 | 2x DVI, 1x S-Video |
API compatibility
List of supported graphics and general-purpose computing APIs, including their specific versions.
| DirectX | 11.1 (11_0) | 9.0c (9_3) |
| Shader Model | 5.0 | 3.0 |
| OpenGL | 4.0 | 2.1 |
| OpenCL | 1.2 | N/A |
| Vulkan | 1.1.80 | N/A |
Synthetic benchmark performance
Non-gaming benchmark performance comparison. The combined score is measured on a 0-100 point scale.
Passmark
This is the most ubiquitous GPU benchmark, part of Passmark PerformanceTest suite. 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.
Benchmark coverage: 25%
GeForce 7800 GTX outperforms HD Graphics by 103% in Passmark.
