GeForce GTX 260 Core 216 vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 is 55% faster than the Radeon R9 M365X in general, due to its greater bandwidth. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 39888 (55%)

Texel Rate

The GeForce GTX 260 Core 216 will be just a bit (approximately 12%) better at anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 4472 (12%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 260 Core 216 is the winner, but it probably won't make a huge difference. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 1328 (9%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
