Nvidia Titan X vs Radeon HD 4730

Intro

Compare all of that to the Radeon HD 4730, which has core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 4730		22400 Mtexels/sec
	Difference: 295008 (1317%)

Pixel Rate

The Nvidia Titan X is quite a bit (about 2329%) more effective at anti-aliasing than the Radeon HD 4730, and will be capable of handling higher screen resolutions more effectively. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 130432 (2329%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
