GeForce GTX 460 2GB vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which has GPU core speed of 926 MHz, and 8192 MB of GDDR5 RAM set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 will be 83% faster than the GeForce GTX 460 2GB in general, due to its greater data rate. (explain)

Radeon RX 470		211200 MB/sec
GeForce GTX 460 2GB		115200 MB/sec
	Difference: 96000 (83%)

Texel Rate

The Radeon RX 470 should be quite a bit (about 214%) more effective at anisotropic filtering than the GeForce GTX 460 2GB. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 80728 (214%)

Pixel Rate

The Radeon RX 470 should be a lot (more or less 37%) more effective at full screen anti-aliasing than the GeForce GTX 460 2GB, and should be capable of handling higher resolutions better. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 8032 (37%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per 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. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
