GeForce GTX 295 vs Radeon R7 M260

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 295 should be a lot faster than the Radeon R7 M260 overall. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 207776 (1299%)

Texel Rate

The GeForce GTX 295 will be quite a bit (approximately 437%) more effective at texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 75000 (437%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 295 is superior to the Radeon R7 M260, by far. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 26536 (464%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
