GeForce GTX 650 Ti 2GB vs Radeon R9 M385X

Intro

The GeForce GTX 650 Ti 2GB features clock speeds of 928 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Compare those specifications to the Radeon R9 M385X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be just a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)

Radeon R9 M385X 96000 MB/sec
GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 9600 (11%)

Texel Rate

The Radeon R9 M385X will be a small bit (more or less 4%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon R9 M385X 61600 Mtexels/sec
GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Difference: 2208 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M385X is the winner, though only just barely. (explain)

Radeon R9 M385X 17600 Mpixels/sec
GeForce GTX 650 Ti 2GB 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video 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 maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
