Radeon HD 5770 vs Radeon HD 6770

Intro

The Radeon HD 5770 has clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 6770, which comes with a GPU core clock speed of 900 MHz, and 512 MB of GDDR5 memory set to run at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon HD 5770 should theoretically be a little bit better than the Radeon HD 6770 overall. (explain)

Radeon HD 5770 76800 MB/sec
Radeon HD 6770 67200 MB/sec
Difference: 9600 (14%)

Texel Rate

The Radeon HD 6770 should be just a bit (about 6%) better at AF than the Radeon HD 5770. (explain)

Radeon HD 6770 36000 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 2000 (6%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 6770 is superior to the Radeon HD 5770, but not by far. (explain)

Radeon HD 6770 14400 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 800 (6%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
