GeForce GTX 260 Core 216 vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which comes with a core clock speed of 715 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 is 599% quicker than the Radeon R7 M260 in general, due to its greater data rate. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 95888 (599%)

Texel Rate

The GeForce GTX 260 Core 216 will be a lot (approximately 142%) better at texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 24312 (142%)

Pixel Rate

The GeForce GTX 260 Core 216 will be much (approximately 182%) more effective at FSAA than the Radeon R7 M260, and also should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10408 (182%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
