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	3
Core clock speed	1029 MHz	1 MHz
Boost clock speed	1124 MHz	350 MHz
Manufacturing process technology	28 nm	90 nm
Power consumption (TDP)	33 Watt	no data
Texture fill rate	17.98	no data
Floating-point performance	863.2 gflops	no data

Form factor & compatibility

Information on GeForce 840M and GeForce 7000M compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. 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.
