GeForce 9800 GT 1GB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M260X should theoretically be just a bit superior to the GeForce 9800 GT 1GB overall. (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%) more effective at texture filtering 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 lots of anti-aliasing is important to you, then the GeForce 9800 GT 1GB is superior to the Radeon R7 M260X, 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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

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