GeForce GTX 650 Ti 2GB vs Radeon R9 M385X

Intro

The GeForce GTX 650 Ti 2GB features a GPU core clock speed of 928 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory perform a bit faster than the GeForce GTX 650 Ti 2GB overall. (explain)

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

Texel Rate

The Radeon R9 M385X should be a bit (approximately 4%) faster with regards to AF 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 running with high levels of AA is important to you, then the Radeon R9 M385X is the winner, but only just. (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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 per 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
