GeForce GTX 650 Ti 2GB vs Radeon R7 M260X

Intro

The GeForce GTX 650 Ti 2GB makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this particular card. It features 768 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends 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 max fill rate.
