GeForce GTX 465 vs GeForce GTX 960M

Intro

Compare those specifications to the GeForce GTX 960M, which uses a 28 nm design. nVidia has clocked the core speed at 1096 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960M		65 Watts
GeForce GTX 465		200 Watts
	Difference: 135 Watts (208%)

Memory Bandwidth

The GeForce GTX 465, in theory, should be a lot faster than the GeForce GTX 960M overall. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 38592 (60%)

Texel Rate

The GeForce GTX 960M should be quite a bit (approximately 64%) faster with regards to AF than the GeForce GTX 465. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 17132 (64%)

Pixel Rate

The GeForce GTX 465 is a bit (about 11%) more effective at full screen anti-aliasing than the GeForce GTX 960M, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 960M		17536 Mpixels/sec
	Difference: 1888 (11%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
