GeForce GTX 285 1GB vs Geforce GTX 760

Intro

Compare all of that to the Geforce GTX 760, which has a core clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Geforce GTX 760		170 Watts
GeForce GTX 285 1GB		204 Watts
	Difference: 34 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 should perform quite a bit faster than the GeForce GTX 285 1GB in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GTX 285 1GB		158976 MB/sec
	Difference: 33280 (21%)

Texel Rate

The Geforce GTX 760 is a lot (more or less 81%) faster with regards to anisotropic filtering than the GeForce GTX 285 1GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GTX 285 1GB		51840 Mtexels/sec
	Difference: 42240 (81%)

Pixel Rate

If running with high levels of AA is important to you, then the Geforce GTX 760 is the winner, by far. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GTX 285 1GB		20736 Mpixels/sec
	Difference: 10624 (51%)

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 (counted in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
