GeForce GTX 965M vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which comes with GPU core 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 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTX 965M is quite a bit (approximately 205%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 40616 (205%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 965M is the winner, and very much so. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 23608 (358%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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