GeForce GTX 460 (OEM) vs Radeon RX 460

Intro

Compare that to the Radeon RX 460, which comes with a clock speed of 1090 MHz and a GDDR5 memory frequency 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		75 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be just a bit faster than the GeForce GTX 460 (OEM) overall. (explain)

Radeon RX 460		112000 MB/sec
GeForce GTX 460 (OEM)		108800 MB/sec
	Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 should be quite a bit (more or less 68%) more effective at texture filtering than the GeForce GTX 460 (OEM). (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 24640 (68%)

Pixel Rate

The GeForce GTX 460 (OEM) should be a little bit (about 19%) better at full screen anti-aliasing than the Radeon RX 460, and also will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 3360 (19%)

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 megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
