GeForce 9800 GTX+ vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which features a GPU core clock speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9800 GTX+ should theoretically be a small bit superior to the Radeon R7 M260X in general. (explain)

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

Texel Rate

The GeForce 9800 GTX+ will be quite a bit (approximately 139%) better at 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 using a high resolution is important to you, then the GeForce 9800 GTX+ is a better choice, and very much so. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
