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	730 MHz	500 MHz
Boost clock speed	780 MHz	no data
Number of transistors	950 million	210 million
Manufacturing process technology	28 nm	80 nm
Power consumption (TDP)	50 Watt	40 Watt
Texture fill rate	18.72	4.000
Floating-point performance	599.0 gflops	no data

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 3.0 x8	PCI
Width	1-slot	IGP
Supplementary power connectors	None	no data

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	System Shared
Maximum RAM amount	2 GB	System Shared
Memory bus width	128 Bit	System Shared
Memory clock speed	1800 MHz	System Shared
Memory bandwidth	28.8 GB/s	no data

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 VGA, 1x S-Video
HDMI	+	no data
