Value for money
Performance to price ratio. The higher, the better.
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 | 320 | 96 |
| Core clock speed | 668 MHz | 320 MHz |
| Boost clock speed | no data | 640 MHz |
| Number of transistors | 666 million | 189 million |
| Manufacturing process technology | 55 nm | 14 nm |
| Power consumption (TDP) | 75 Watt | 6 Watt |
| Texture fill rate | 10.69 | 7.680 |
| Floating-point performance | 427.5 gflops | 134.4 gflops |
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 | AGP 8x | PCIe 3.0 x1 |
| Width | 1-slot | IGP |
| Supplementary power connectors | 1x 8-pin | no data |
Memory
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 | GDDR3 | DDR3L |
| Maximum RAM amount | 512 MB | 8 GB |
| Memory bus width | 256 Bit | System Shared |
| Memory clock speed | 1656 MHz | System Shared |
| Memory bandwidth | 52.99 GB/s | 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 | 2x DVI, 1x S-Video | No outputs |
API support
List of supported graphics and general-purpose computing APIs, including their specific versions.
| DirectX | 10.1 (10_1) | 12 (11_1) |
| Shader Model | 4.1 | 5.1 |
| OpenGL | 3.3 | 4.3 |
| OpenCL | N/A | 2.0 |
| Vulkan | N/A | 1.1.80 |
