GeForce GTS 150 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which has clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375 should be a bit faster than the GeForce GTS 150 in general. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 3200 (10%)

Texel Rate

The GeForce GTS 150 should be a little bit (approximately 17%) more effective at anisotropic filtering than the Radeon R9 M375. (explain)

GeForce GTS 150		47360 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 6760 (17%)

Pixel Rate

The Radeon R9 M375 will be much (about 37%) more effective at full screen anti-aliasing than the GeForce GTS 150, and able to handle higher resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 4400 (37%)

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 max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of 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 processed per second.

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