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	720	800
Core clock speed	700 MHz	750 MHz
Number of transistors	1,040 million	956 million
Manufacturing process technology	40 nm	55 nm
Power consumption (TDP)	86 Watt	150 Watt
Texture fill rate	25.20	30.00
Floating-point performance	1,008.0 gflops	1,200.0 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	PCIe 2.0 x16
Length	178 mm	250 mm
Width	2-slot	2-slot
Supplementary power connectors	1x 6-pin	2x 6-pin

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	512 MB
Memory bus width	128 Bit	256 Bit
Memory clock speed	4600 MHz	3400 MHz
