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	240	96
Core clock speed	601 MHz	550 MHz
Number of transistors	720 million	727 million
Manufacturing process technology	80 nm	40 nm
Power consumption (TDP)	150 Watt	69 Watt
Texture fill rate	7.212	17.60
Floating-point performance	288.48 gflops	257.28 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 1.0 x16	PCIe 2.0 x16
Length	no data	168 mm
Width	2-slot	1-slot
Supplementary power connectors	1x 8-pin	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	GDDR3
Maximum RAM amount	256 MB	1 GB
Memory bus width	256 Bit	128 Bit
Memory clock speed	1600 MHz	1700 MHz
Memory bandwidth	51.2 GB/s	27.2 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	2x DVI, 1x S-Video	1x DVI, 1x HDMI, 1x VGA
HDMI	no data	+
