GeForce 840M vs Radeon R7 M360

Intro

The GeForce 840M comes with a clock speed of 1029 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare those specs to the Radeon R7 M360, which has a clock frequency of 1125 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon R7 M360 is a small bit (about 9%) faster with regards to texture filtering than the GeForce 840M. (explain)

Radeon R7 M360 27000 Mtexels/sec
GeForce 840M 24696 Mtexels/sec
Difference: 2304 (9%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 M360 is superior to the GeForce 840M, but not by far. (explain)

Radeon R7 M360 9000 Mpixels/sec
GeForce 840M 8232 Mpixels/sec
Difference: 768 (9%)

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 data (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
