GeForce GTX 950 vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 950 should theoretically be a small bit better than the Radeon R9 M385X in general. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 9728 (10%)

Texel Rate

The Radeon R9 M385X will be much (approximately 25%) more effective at anisotropic 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 using high levels of AA is important to you, then the GeForce GTX 950 is superior to the Radeon R9 M385X, and very much so. (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 information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied 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 better this number, the better the video 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 that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
