Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GTX+ will be 100% quicker than the Radeon R9 M375 overall, due to its higher data rate. (explain)

GeForce 9800 GTX+		70400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 35200 (100%)

Texel Rate

The GeForce 9800 GTX+ is a bit (about 16%) faster with regards to AF than the Radeon R9 M375. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 6632 (16%)

Pixel Rate

The Radeon R9 M375 should be quite a bit (about 38%) more effective at FSAA than the GeForce 9800 GTX+, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M375		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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of 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.
