GeForce GTX 460 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has clocked the core frequency at 1090 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 460		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Performance-wise, the Radeon RX 460 2GB should theoretically be quite a bit superior to the GeForce GTX 460 overall. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 25600 (30%)

Texel Rate

The Radeon RX 460 2GB should be quite a bit (about 61%) more effective at anisotropic filtering than the GeForce GTX 460. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 23240 (61%)

Pixel Rate

The Radeon RX 460 2GB is just a bit (about 8%) better at AA than the GeForce GTX 460, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 1240 (8%)

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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 max fill rate.
