Radeon HD 5850 vs Radeon HD 6870

Intro

The Radeon HD 5850 comes with core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs as well as 72 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 6870, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 1120 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon HD 6870 should be a small bit faster than the Radeon HD 5850 overall. (explain)

Radeon HD 6870 134400 MB/sec
Radeon HD 5850 128000 MB/sec
Difference: 6400 (5%)

Texel Rate

The Radeon HD 5850 is a bit (more or less 4%) faster with regards to texture filtering than the Radeon HD 6870. (explain)

Radeon HD 5850 52200 Mtexels/sec
Radeon HD 6870 50400 Mtexels/sec
Difference: 1800 (4%)

Pixel Rate

The Radeon HD 6870 should be a lot (about 24%) faster with regards to anti-aliasing than the Radeon HD 5850, and also will be capable of handling higher resolutions better. (explain)

Radeon HD 6870 28800 Mpixels/sec
Radeon HD 5850 23200 Mpixels/sec
Difference: 5600 (24%)

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 max amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
