GeForce GTX 950M vs Radeon R7 M260X

Intro

The GeForce GTX 950M has a clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X will be 100% faster than the GeForce GTX 950M in general, because of its greater data rate. (explain)

Radeon R7 M260X 64000 MB/sec
GeForce GTX 950M 32000 MB/sec
Difference: 32000 (100%)

Texel Rate

The GeForce GTX 950M is quite a bit (about 85%) more effective at texture filtering than the Radeon R7 M260X. (explain)

GeForce GTX 950M 36560 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 16760 (85%)

Pixel Rate

The GeForce GTX 950M will be a lot (more or less 122%) more effective at FSAA than the Radeon R7 M260X, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 950M 14624 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 8024 (122%)

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 (in units of MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
