GeForce GTX 285 2GB vs GeForce GTX 970

Intro

Compare all that to the GeForce GTX 970, which comes with core clock speeds of 1050 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1664 SPUs as well as 104 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970		145 Watts
GeForce GTX 285 2GB		204 Watts
	Difference: 59 Watts (41%)

Memory Bandwidth

Theoretically, the GeForce GTX 970 should perform quite a bit faster than the GeForce GTX 285 2GB in general. (explain)

GeForce GTX 970		224000 MB/sec
GeForce GTX 285 2GB		158976 MB/sec
	Difference: 65024 (41%)

Texel Rate

The GeForce GTX 970 should be a lot (more or less 111%) better at AF than the GeForce GTX 285 2GB. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GTX 285 2GB		51840 Mtexels/sec
	Difference: 57360 (111%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970 is the winner, and very much so. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 46464 (224%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
