GeForce GTX 650 Ti vs Radeon R9 M385X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should theoretically be a little bit faster than the GeForce GTX 650 Ti overall. (explain)

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

Texel Rate

The Radeon R9 M385X is a small bit (about 4%) better at anisotropic 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 using a high resolution is important to you, then the Radeon R9 M385X is the winner, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
