GeForce GTX Titan Black vs Radeon HD 4730

Intro

Compare those specifications to the Radeon HD 4730, which features a clock speed of 700 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 8 ROPs.

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

Theoretically speaking, the GeForce GTX Titan Black is 483% quicker than the Radeon HD 4730 overall, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTX Titan Black should be quite a bit (more or less 853%) better at anisotropic 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 lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is the winner, and very much so. (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: Memory bandwidth is the largest amount of data (counted in 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 speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 maximum number of pixels that the graphics card could possibly write to its 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 the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
