GeForce GTX 460 1GB vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which comes with a core clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 85 Watts (113%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB is 3% faster than the Radeon RX 460 2GB in general, because of its greater data rate. (explain)

GeForce GTX 460 1GB		115200 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 2GB should be quite a bit (approximately 61%) better at AF than the GeForce GTX 460 1GB. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 23240 (61%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is a better choice, and very much so. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon RX 460 2GB		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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
