Geforce GTX 770 vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which has GPU core speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Geforce GTX 770 should perform quite a bit faster than the Radeon R7 M260X in general. (explain)

Geforce GTX 770		224384 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 160384 (251%)

Texel Rate

The Geforce GTX 770 should be a lot (approximately 576%) more effective at AF than the Radeon R7 M260X. (explain)

Geforce GTX 770		133888 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 114088 (576%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 770 is the winner, by a large margin. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 26872 (407%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock 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 applied in one second.

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