GeForce 9800 GTX+ vs Radeon R9 M375X

Intro

The GeForce 9800 GTX+ has a GPU clock speed of 738 MHz, and the 512 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon R9 M375X, which comes with a core clock speed of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be a little 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+ should be just a bit (about 16%) faster with regards to 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 screen resolution is important to you, then the Radeon R9 M375X is the winner, and very much so. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
