Value for money
Performance to price ratio. The higher, the better.
ATI HD 4550 and ATI HD 4650 have a nearly equal value for money.
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.

| Maximum RAM amount | 256 MB | 256 MB |
| Memory bus width | 64 Bit | 128 Bit |
| Memory clock speed | 1310 MHz | 1400 MHz |
| Memory bandwidth | 10.48 GB/s | 22.4 GB/s |
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 | 1x DVI, 1x HDMI, 1x DisplayPort | 2x DVI, 1x S-Video |
| HDMI | + | no data |

Combined synthetic benchmark score
This is our combined benchmark performance score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
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 4650 outperforms HD 4550 by 1% in Passmark.
