GeForce GTX 260 Core 216 vs Radeon R9 M365X

Intro

Compare that to the Radeon R9 M365X, which has a GPU core clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 should perform much faster than the Radeon R9 M365X overall. (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 is just a bit (approximately 12%) more effective at AF 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 high levels of AA is important to you, then the GeForce GTX 260 Core 216 is a better choice, but only just. (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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of 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.
