GeForce 940M vs Radeon HD 6750 1GB

Intro

The GeForce 940M has a GPU core speed of 1072 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Compare all of that to the Radeon HD 6750 1GB, which has GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 720 SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 6750 1GB should theoretically be a lot better than the GeForce 940M overall. (explain)

Radeon HD 6750 1GB 64000 MB/sec
GeForce 940M 16000 MB/sec
Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 1GB should be a small bit (more or less 1%) better at texture filtering than the GeForce 940M. (explain)

Radeon HD 6750 1GB 26100 Mtexels/sec
GeForce 940M 25728 Mtexels/sec
Difference: 372 (1%)

Pixel Rate

The Radeon HD 6750 1GB will be much (more or less 35%) more effective at AA than the GeForce 940M, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 6750 1GB 11600 Mpixels/sec
GeForce 940M 8576 Mpixels/sec
Difference: 3024 (35%)

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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
