GeForce GTX 460 1GB vs Geforce GTX 760

Intro

Compare those specifications to the Geforce GTX 760, which has GPU core speed of 980 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also is made up of 1152 SPUs, 96 TAUs, and 32 ROPs.

GeForce GTX 460 1GB		115200 MB/sec
	Difference: 77056 (67%)

Texel Rate

The Geforce GTX 760 should be much (approximately 149%) more effective at texture filtering than the GeForce GTX 460 1GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 56280 (149%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 760 is a better choice, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 9760 (45%)

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 data (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 are processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
