Nvidia Titan X vs Radeon HD 4750

Intro

The Nvidia Titan X features a GPU core speed of 1417 MHz, and the 12288 MB of GDDR5X RAM runs at 1251 MHz through a 384-bit bus. It also is made up of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

Compare those specs to the Radeon HD 4750, which features a GPU core clock speed of 730 MHz, and 512 MB of GDDR5 RAM running at 800 MHz through a 128-bit bus. It also features 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
