GeForce 9800 GTX vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which comes with GPU core speed of 1015 MHz, and 4096 MB of DDR3 RAM set to run at 1100 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 9800 GTX should in theory be a lot better than the Radeon R9 M375 overall. (explain)

GeForce 9800 GTX		70400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 35200 (100%)

Texel Rate

The GeForce 9800 GTX is a bit (more or less 6%) more effective at AF than the Radeon R9 M375. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 2600 (6%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375 is the winner, by a large margin. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 5440 (50%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
