Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

Detailed specifications

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	896	512
Core clock speed	1000 MHz	686 MHz
Boost clock speed	no data	980 MHz
Number of transistors	2,080 million	2,410 million
Manufacturing process technology	28 nm	28 nm
Power consumption (TDP)	85 Watt	15 Watt
Texture fill rate	56.00	31.36
Floating-point performance	1,792 gflops	526.8 gflops

Form factor & 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 x16	IGP
Length	183 mm	no data
Width	2-slot	IGP
Supplementary power connectors	1x 6-pin	no data

VRAM capacity and type

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	GDDR5	System Shared
Maximum RAM amount	1 GB	System Shared
Memory bus width	128 Bit	System Shared
Memory clock speed	6000 MHz	System Shared
Memory bandwidth	96 GB/s	no data

Connectivity and outputs

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, 2x mini-DisplayPort	No outputs
HDMI	+	no data

API compatibility

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