Value for money

Performance to price ratio. The higher, the better.

ATI HD 5550 and ATI HD 4670 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.

Core clock speed	550 MHz	750 MHz
Number of transistors	627 million	514 million
Manufacturing process technology	40 nm	55 nm
Power consumption (TDP)	39 Watt	59 Watt
Texture fill rate	8.800	24.00
Floating-point performance	352.0 gflops	480.0 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).

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	GDDR5	GDDR3
Maximum RAM amount	2 GB	512 MB
Memory bus width	128 Bit	128 Bit
Memory clock speed	3200 MHz	2000 MHz
Memory bandwidth	51.2 GB/s	32 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 VGA	2x DVI, 1x S-Video
HDMI	+	no data
