GeForce 9800 GTX+ vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M370X should in theory be a small bit superior to the GeForce 9800 GTX+ in general. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX+ is quite a bit (more or less 48%) more effective at texture filtering than the Radeon R9 M370X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 15232 (48%)

Pixel Rate

The Radeon R9 M370X should be a small bit (approximately 8%) more effective at AA than the GeForce 9800 GTX+, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 992 (8%)

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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
