GeForce GTX 460 1GB vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which features core clock 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 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 85 Watts (113%)

Memory Bandwidth

In theory, the GeForce GTX 460 1GB will be 3% quicker than the Radeon RX 460 overall, because of its greater bandwidth. (explain)

GeForce GTX 460 1GB		115200 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 will be quite a bit (more or less 61%) faster with regards to anisotropic filtering than the GeForce GTX 460 1GB. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 23240 (61%)

Pixel Rate

The GeForce GTX 460 1GB should be quite a bit (more or less 24%) more effective at anti-aliasing than the Radeon RX 460, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 4160 (24%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
