GeForce 9800 GT 512MB vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which comes with a clock speed of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GT 512MB is 260% faster than the Radeon R7 M260 in general, because of its higher data rate. (explain)

GeForce 9800 GT 512MB		57600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The GeForce 9800 GT 512MB should be quite a bit (more or less 96%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

GeForce 9800 GT 512MB		33600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 16440 (96%)

Pixel Rate

The GeForce 9800 GT 512MB will be a lot (about 68%) faster with regards to AA than the Radeon R7 M260, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce 9800 GT 512MB		9600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 3880 (68%)

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 transferred across the external memory interface in one second. It's 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 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
