GeForce 930M vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 ROPs.

GeForce 930M		22272 Mtexels/sec
	Difference: 39328 (177%)

Pixel Rate

The Radeon R9 M385X will be a lot (about 137%) better at AA than the GeForce 930M, and capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 10176 (137%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
