GeForce 940M vs Radeon R7 250

Intro

The GeForce 940M features a clock speed of 1072 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon R7 250, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1150 MHz on this model. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 250 should in theory be quite a bit better than the GeForce 940M overall. (explain)

Radeon R7 250 73600 MB/sec
GeForce 940M 16000 MB/sec
Difference: 57600 (360%)

Texel Rate

The GeForce 940M should be a small bit (about 7%) faster with regards to texture filtering than the Radeon R7 250. (explain)

GeForce 940M 25728 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 1728 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 940M is a better choice, but it probably won't make a huge difference. (explain)

GeForce 940M 8576 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 576 (7%)

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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could 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 colour ROPs by the the core speed of the card. 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 of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
