GeForce 940M vs Radeon HD 3850 1GB

Intro

The GeForce 940M comes with a GPU core clock speed of 1072 MHz, and the 2048 MB of DDR3 memory is set to run at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare that to the Radeon HD 3850 1GB, which has GPU core speed of 668 MHz, and 1024 MB of GDDR3 RAM set to run at 828 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3850 1GB should be 231% faster than the GeForce 940M in general, because of its higher data rate. (explain)

Radeon HD 3850 1GB 52992 MB/sec
GeForce 940M 16000 MB/sec
Difference: 36992 (231%)

Texel Rate

The GeForce 940M will be much (about 141%) faster with regards to AF than the Radeon HD 3850 1GB. (explain)

GeForce 940M 25728 Mtexels/sec
Radeon HD 3850 1GB 10688 Mtexels/sec
Difference: 15040 (141%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 3850 1GB is superior to the GeForce 940M, and very much so. (explain)

Radeon HD 3850 1GB 10688 Mpixels/sec
GeForce 940M 8576 Mpixels/sec
Difference: 2112 (25%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends 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.
