GeForce GTX 465 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which has core speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

GeForce GTX 465		102592 MB/sec
	Difference: 9408 (9%)

Texel Rate

The Radeon RX 460 will be much (about 129%) faster with regards to texture filtering than the GeForce GTX 465. (explain)

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

Pixel Rate

The GeForce GTX 465 is just a bit (approximately 11%) more effective at AA than the Radeon RX 460, and also able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon RX 460		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 largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
