GeForce GTX 465 vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which has clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units 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 in theory be just a bit better than the GeForce GTX 465 overall. (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 (about 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

The GeForce GTX 465 is a little bit (more or less 11%) faster with regards to full screen anti-aliasing than the Radeon RX 460 2GB, and also will be capable of handling higher resolutions while still performing well. (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 data (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 applied in a second.

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