| Width | 1-slot | 1-slot |
| Supplementary power connectors | 1x 6-pin | None |
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 | DDR2 |
| Maximum RAM amount | 512 MB | 2 GB |
| Memory bus width | 256 Bit | 64 Bit |
| Memory clock speed | 1800 MHz | 800 MHz |
| Memory bandwidth | 57.6 GB/s | 6.4 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 | 2x DVI, 1x S-Video | 1x DVI, 1x HDMI, 1x VGA |
| HDMI | no data | + |
API Compatibility
List of supported graphics and general-purpose computing APIs, including their specific versions.

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%
HD 4830 outperforms HD 5450 by 514% in Passmark.
