Radeon HD 6850 vs Radeon HD 7770

Intro

The Radeon HD 6850 comes with a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 960 Stream Processors, 48 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon HD 7770, which has clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7770 80 Watts
Radeon HD 6850 127 Watts
Difference: 47 Watts (59%)

Memory Bandwidth

Performance-wise, the Radeon HD 6850 should in theory be a lot better than the Radeon HD 7770 overall. (explain)

Radeon HD 6850 128000 MB/sec
Radeon HD 7770 72000 MB/sec
Difference: 56000 (78%)

Texel Rate

The Radeon HD 7770 should be a bit (approximately 8%) better at AF than the Radeon HD 6850. (explain)

Radeon HD 7770 40000 Mtexels/sec
Radeon HD 6850 37200 Mtexels/sec
Difference: 2800 (8%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6850 is a better choice, by far. (explain)

Radeon HD 6850 24800 Mpixels/sec
Radeon HD 7770 16000 Mpixels/sec
Difference: 8800 (55%)

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 (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be processed per second. This number 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
