GeForce 9800 GTX+ vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GTX+ should be 10% faster than the Radeon R7 M260X in general, due to its greater bandwidth. (explain)

GeForce 9800 GTX+		70400 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce 9800 GTX+ should be much (about 139%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 27432 (139%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9800 GTX+ is the winner, by far. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5208 (79%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
