GeForce GTX 285 2GB vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which features GPU clock speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
GeForce GTX 285 2GB		204 Watts
	Difference: 84 Watts (70%)

Memory Bandwidth

In theory, the Radeon RX 470 should be 33% quicker than the GeForce GTX 285 2GB in general, due to its greater bandwidth. (explain)

Radeon RX 470		211200 MB/sec
GeForce GTX 285 2GB		158976 MB/sec
	Difference: 52224 (33%)

Texel Rate

The Radeon RX 470 should be quite a bit (approximately 129%) more effective at AF than the GeForce GTX 285 2GB. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 285 2GB		51840 Mtexels/sec
	Difference: 66688 (129%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 470 is a better choice, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 8896 (43%)

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 megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
