GeForce 9800 GT 1GB vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which features a core clock speed of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X should be quite a bit (about 21%) faster with regards to anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375X is quite a bit (more or less 69%) more effective at full screen anti-aliasing than the GeForce 9800 GT 1GB, and will be able to handle higher resolutions better. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 6640 (69%)

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 (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high 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 amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
