GeForce GTX 965M vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which comes with a core clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce GTX 965M will be much (approximately 205%) more effective at texture filtering than the Radeon R7 M260X. (explain)

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

Pixel Rate

The GeForce GTX 965M will be quite a bit (approximately 358%) more effective at FSAA than the Radeon R7 M260X, and will be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
