GeForce GTX 460 SE vs GeForce GTX 950

Intro

Compare those specifications to the GeForce GTX 950, which has a clock speed of 1024 MHz and a GDDR5 memory speed of 1652 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 768 SPUs, 48 Texture Address Units, and 32 ROPs.

GeForce GTX 950		105728 MB/sec
	Difference: 3072 (3%)

Texel Rate

The GeForce GTX 950 will be much (more or less 58%) better at texture filtering than the GeForce GTX 460 SE. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 17952 (58%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950 is superior to the GeForce GTX 460 SE, by a large margin. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 11968 (58%)

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 data (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
