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	16	384
Core clock speed	520 MHz	900 MHz
Boost clock speed	no data	1050 MHz
Number of transistors	260 million	950 million
Manufacturing process technology	40 nm	28 nm
Power consumption (TDP)	40 Watt	65 Watt
Texture fill rate	4.160	21.60
Floating-point performance	39.36 gflops	806.4 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).

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	DDR3
Maximum RAM amount	512 MB	2 GB
Memory bus width	64 Bit	64 Bit
Memory clock speed	1000 MHz	2000 MHz
Memory bandwidth	8 GB/s	16 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 DisplayPort
HDMI	+	no data
