GeForce GTX 465 vs Radeon RX 460 2GB

Intro

Compare that to the Radeon RX 460 2GB, which comes with GPU core speed of 1090 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

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

The Radeon RX 460 2GB, in theory, should perform a bit faster than 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 should be a lot (more or less 129%) more effective at texture filtering 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 using lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, but it probably won't make a huge difference. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
