GeForce GTX 650 Ti vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which uses a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this specific card. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be a little bit faster than the GeForce GTX 650 Ti in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The Radeon R9 M385X should be a little bit (more or less 4%) more effective at texture filtering than the GeForce GTX 650 Ti. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 2208 (4%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M385X is the winner, not by a very large margin though. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 2752 (19%)

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 maximum amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock 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 most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
