GeForce GTX 950 vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which has a core clock frequency of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Radeon R9 M385X		96000 MB/sec
	Difference: 9728 (10%)

Texel Rate

The Radeon R9 M385X will be much (more or less 25%) better at texture filtering than the GeForce GTX 950. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 12448 (25%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950 is superior to the Radeon R9 M385X, by a large margin. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 15168 (86%)

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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
