GeForce GTX 465 vs Radeon RX 460 2GB

Intro

Compare those specs to the Radeon RX 460 2GB, which features a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 465		200 Watts
	Difference: 125 Watts (167%)

Memory Bandwidth

As far as performance goes, the Radeon RX 460 2GB should theoretically be a bit superior to the GeForce GTX 465 in general. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 9408 (9%)

Texel Rate

The Radeon RX 460 2GB is a lot (more or less 129%) more effective at AF than the GeForce GTX 465. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 34332 (129%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, not by a very large margin though. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 1984 (11%)

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 (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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.
