| Manufacturing process technology | 40 nm | 28 nm |
| Power consumption (TDP) | 25 Watt | 15 Watt |
| Texture fill rate | 5.000 | 31.36 |
| Floating-point performance | 200.0 gflops | 526.8 gflops |
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 | MXM-A (3.0) | IGP |
| Width | MXM Module | IGP |
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 | GDDR3 | System Shared |
| Maximum RAM amount | 512 MB | System Shared |
| Memory bus width | 64 Bit | System Shared |
| Memory clock speed | 1600 MHz | System Shared |
| Memory bandwidth | 12.8 GB/s | no data |
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 | No outputs |
