Form factor & compatibility
Information on HD Graphics 2000 and Radeon HD 6450A 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). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
| Interface | PCIe 1.0 x16 | MXM-A (3.0) |
| Width | no data | MXM Module |
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 | no data | DDR3 |
| Maximum RAM amount | System Shared | 512 MB |
| Memory bus width | 64/128 Bit | 64 Bit |
| Memory clock speed | no data | 1066 MHz |
| Memory bandwidth | no data | 8.528 GB/s |
| Shared memory | + | 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 |
API compatibility
List of supported graphics and general-purpose computing APIs, including their specific versions.
| DirectX | 11.1 (10_1) | 11.2 (11_0) |
| Shader Model | 4.1 | 5.0 |
| OpenGL | 3.1 | 4.4 |
| OpenCL | N/A | 1.2 |

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.
