GeForce 9800 GT 1GB vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which comes with a clock speed of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of 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 Radeon R7 M260X should perform a small bit faster than the GeForce 9800 GT 1GB in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9800 GT 1GB should be a lot (more or less 70%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 13800 (70%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9800 GT 1GB is a better choice, and very much so. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 3000 (45%)

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 (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
