Geforce GTX 670 vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which has core clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Geforce GTX 670 should in theory be much better than the Radeon R7 M260X in general. (explain)

Geforce GTX 670		192000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 128000 (200%)

Texel Rate

The Geforce GTX 670 will be quite a bit (approximately 418%) more effective at AF than the Radeon R7 M260X. (explain)

Geforce GTX 670		102480 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 82680 (418%)

Pixel Rate

The Geforce GTX 670 is a lot (more or less 344%) better at full screen anti-aliasing than the Radeon R7 M260X, and should be capable of handling higher resolutions without losing too much performance. (explain)

Geforce GTX 670		29280 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 22680 (344%)

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 max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
