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	1082 MHz	598 MHz
Boost clock speed	1150 MHz	no data
Number of transistors	no data	716 million
Manufacturing process technology	28 nm	40 nm
Power consumption (TDP)	33 Watt	35 Watt
Texture fill rate	18.40	14.35
Floating-point performance	588.8 gflops	574.1 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 3.0 x8	MXM-A (3.0)
Width	IGP	MXM Module

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	2 GB	512 MB
Memory bus width	64 Bit	128 Bit
Memory clock speed	1800 MHz	3176 MHz
Memory bandwidth	14.4 GB/s	50.82 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.
