Value for money

Performance to price ratio. The higher, the better.

ATI HD 5670 has 400% better value for money than GT 820M.

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.

Pipelines / CUDA cores	96	400
Core clock speed	775 MHz	775 MHz
Number of transistors	585 million	627 million
Manufacturing process technology	28 nm	40 nm
Power consumption (TDP)	15 Watt	64 Watt
Texture fill rate	12.40	15.50
Floating-point performance	297.6 gflops	620.0 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).

Interface	PCIe 2.0 x16	PCIe 2.0 x16
Length	no data	168 mm
Width	no data	1-slot
Supplementary power connectors	no data	None

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	DDR3	GDDR5
Maximum RAM amount	1 GB	1 GB
Memory bus width	64 Bit	128 Bit
Memory clock speed	1800 MHz	1000 MHz
Memory bandwidth	14.4 GB/s	64 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	No outputs	1x DVI, 1x HDMI, 1x VGA
HDMI	no data	+
