GeForce 930M vs Radeon HD 7790

Intro

The GeForce 930M uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon HD 7790, which has GPU core speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the 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 maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
