GeForce GTX 460 SE vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which has a GPU core clock speed of 1024 MHz, and 2048 MB of GDDR5 memory running at 1652 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 48 TAUs, and 32 Raster Operation Units.

GeForce GTX 950		90 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 60 Watts (67%)

Memory Bandwidth

Performance-wise, the GeForce GTX 460 SE should in theory be just a bit superior to the GeForce GTX 950 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 3072 (3%)

Texel Rate

The GeForce GTX 950 will be much (approximately 58%) more effective at AF 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 a high screen resolution is important to you, then the GeForce GTX 950 is the winner, by far. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
