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.

Core clock speed	850 MHz	800 MHz
Number of transistors	1,040 million	1,040 million
Manufacturing process technology	40 nm	40 nm
Power consumption (TDP)	108 Watt	100 Watt
Texture fill rate	34.00	32.00
Floating-point performance	1,360.0 gflops	1,280.0 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 2.0 x16	MXM-B (3.0)
Length	208 mm	no data
Width	2-slot	MXM Module
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	GDDR5
Maximum RAM amount	1 GB	1 GB
Memory bus width	128 Bit	128 Bit
Memory clock speed	4800 MHz	4400 MHz
