GeForce GTX 460 (OEM) vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which makes use of a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM works at a frequency of 1625 MHz on this specific model. 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 R7 260X		115 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 35 Watts (30%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) will be 5% quicker than the Radeon R7 260X in general, due to its higher data rate. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 4800 (5%)

Texel Rate

The Radeon R7 260X should be quite a bit (more or less 69%) faster with regards to texture filtering than the GeForce GTX 460 (OEM). (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 25200 (69%)

Pixel Rate

The GeForce GTX 460 (OEM) is a little bit (more or less 18%) more effective at anti-aliasing than the Radeon R7 260X, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 3200 (18%)

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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
