GeForce GTX 465 vs GeForce GTX 960M

Intro

Compare those specifications to the GeForce GTX 960M, which features clock speeds of 1096 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units 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

Theoretically, the GeForce GTX 465 should perform 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 a lot (more or less 64%) better at anisotropic filtering than the GeForce GTX 465. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 465 is superior to the GeForce GTX 960M, not by a very large margin though. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
