GeForce GTX 275 vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which has a core clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
GeForce GTX 275		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 275 should be 13% quicker than the Radeon RX 460 overall, because of its higher bandwidth. (explain)

GeForce GTX 275		127008 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 15008 (13%)

Texel Rate

The Radeon RX 460 should be much (more or less 21%) better at anisotropic filtering than the GeForce GTX 275. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 10400 (21%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 275 is a better choice, but not by far. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 284 (2%)

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 information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. 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 card's memory bandwidth, the better 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 applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
