GeForce 9800 GT 1GB vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X should in theory perform a lot faster than the GeForce 9800 GT 1GB in general. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 9800 GT 1GB is just a bit (about 5%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1600 (5%)

Pixel Rate

The Radeon R9 M370X should be quite a bit (about 33%) better at FSAA than the GeForce 9800 GT 1GB, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 9800 GT 1GB		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 max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's 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 max fill rate.
