GeForce 9800 GTX+ vs Radeon R9 M375X

Intro

Compare that to the Radeon R9 M375X, which features core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be just a bit better than the GeForce 9800 GTX+ in general. (explain)

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

Texel Rate

The GeForce 9800 GTX+ is a little bit (about 16%) better at texture filtering than the Radeon R9 M375X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 6632 (16%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is the winner, by far. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 4432 (38%)

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 data (in units of MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
