GeForce GTX Titan Black vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which comes with a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1120(224x5) Stream Processors, 56 Texture Address Units, and 16 ROPs.

	Difference: 208000 (163%)

Texel Rate

The GeForce GTX Titan Black should be quite a bit (about 376%) faster with regards to texture filtering than the Radeon HD 5830. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 168560 (376%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX Titan Black is a better choice, by far. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 29872 (233%)

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 maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
