Value for money

Performance to price ratio. The higher, the better.

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	80	48
Core clock speed	650 MHz	700 MHz
Number of transistors	292 million	585 million
Manufacturing process technology	40 nm	40 nm
Power consumption (TDP)	19 Watt	50 Watt
Texture fill rate	5.200	2.800
Floating-point performance	104.0 gflops	134.4 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	170 mm	145 mm
Width	1-slot	1-slot
Supplementary power connectors	None	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	GDDR3	DDR3
Maximum RAM amount	512 MB	1 GB
Memory bus width	64 Bit	128 Bit
Memory clock speed	800 MHz	1800 MHz
Memory bandwidth	6.4 GB/s	28.8 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	1x DVI, 1x HDMI, 1x VGA
HDMI	+	+

API support

List of supported graphics and general-purpose computing APIs, including their specific versions.
