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	384	80
Core clock speed	950 MHz	280 MHz
Number of transistors	1,270 million	292 million
Manufacturing process technology	28 nm	40 nm
Power consumption (TDP)	50 Watt	19 Watt
Texture fill rate	30.40	5.200
Floating-point performance	729.6 gflops	104 gflops

Form factor & compatibility

Information on GeForce GTX 660M Mac Edition and Radeon HD 6250 compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

Interface	MXM-B (3.0)	PCIe 2.0 x16
Width	MXM Module	no data
Supplementary power connectors	None	None

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	GDDR3
Maximum RAM amount	512 MB	512 MB
Memory bus width	128 Bit	64 Bit
Memory clock speed	5000 MHz	1000 MHz
