GeForce GTX Titan Black vs Radeon HD 4730

Intro

Compare all of that to the Radeon HD 4730, which has a GPU core clock speed of 700 MHz, and 512 MB of GDDR5 RAM running at 900 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4730		140 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 110 Watts (79%)

Memory Bandwidth

The GeForce GTX Titan Black should in theory be a lot faster than the Radeon HD 4730 in general. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon HD 4730		57600 MB/sec
	Difference: 278400 (483%)

Texel Rate

The GeForce GTX Titan Black will be quite a bit (more or less 853%) faster with regards to texture filtering than the Radeon HD 4730. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 190960 (853%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan Black is a better choice, by a large margin. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 37072 (662%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
