GeForce GTX 560 vs Radeon HD 5830

Intro

The GeForce GTX 560 has a GPU core clock speed of 810 MHz, and the 1024 MB of GDDR5 memory is set to run at 1001 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 ROPs.

Compare those specs to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular card. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 150 Watts
Radeon HD 5830 175 Watts
Difference: 25 Watts (17%)

Memory Bandwidth

In theory, the GeForce GTX 560 will be 0% faster than the Radeon HD 5830 in general, because of its greater data rate. (explain)

GeForce GTX 560 128128 MB/sec
Radeon HD 5830 128000 MB/sec
Difference: 128 (0%)

Texel Rate

The GeForce GTX 560 should be just a bit (approximately 1%) better at texture filtering than the Radeon HD 5830. (explain)

GeForce GTX 560 45360 Mtexels/sec
Radeon HD 5830 44800 Mtexels/sec
Difference: 560 (1%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is superior to the Radeon HD 5830, by a large margin. (explain)

GeForce GTX 560 25920 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 13120 (103%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
