GeForce GTX 465 vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which comes with a core clock speed of 914 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 950M		55 Watts
GeForce GTX 465		200 Watts
	Difference: 145 Watts (264%)

Memory Bandwidth

Theoretically, the GeForce GTX 465 should be a lot faster than the GeForce GTX 950M in general. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 70592 (221%)

Texel Rate

The GeForce GTX 950M should be quite a bit (about 37%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 9852 (37%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 465 is the winner, by a large margin. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 4800 (33%)

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 largest amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
