GeForce 9800 GT 512MB vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which features a clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

	Difference: 14400 (25%)

Texel Rate

The GeForce 9800 GT 512MB will be just a bit (more or less 5%) better at texture filtering than the Radeon R9 M370X. (explain)

GeForce 9800 GT 512MB		33600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1600 (5%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is a better choice, by a large margin. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 9800 GT 512MB		9600 Mpixels/sec
	Difference: 3200 (33%)

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 megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
