GeForce GTX 460 2GB vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which has GPU core 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 Texture Address Units, and 32 ROPs.

GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 11352 (30%)

Pixel Rate

The GeForce GTX 950 should be a lot (approximately 52%) better at anti-aliasing than the GeForce GTX 460 2GB, and also will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 11168 (52%)

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 maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
