GeForce 9800 GTX vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should in theory perform a small bit faster than the GeForce 9800 GTX overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9800 GTX		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX should be a bit (approximately 6%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 2600 (6%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the GeForce 9800 GTX, by a large margin. (explain)

Radeon R9 M375X		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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 are processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
