Geforce GTX 770 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which features a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Geforce GTX 770 should perform a lot faster than the Radeon R7 M260X overall. (explain)

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

Texel Rate

The Geforce GTX 770 will be much (more or less 576%) more effective at anisotropic filtering 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 superior to the Radeon R7 M260X, by far. (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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, 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 can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
