GeForce GTX 465 vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 memory works at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

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

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 37%) faster with regards to texture 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 far. (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: Memory 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. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
