Radeon HD 5670 vs Radeon HD 6770 1GB

Intro

The Radeon HD 5670 has clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Compare all that to the Radeon HD 6770 1GB, which has a core clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 800 SPUs, 40 TAUs, and 16 ROPs.

Radeon HD 5670 64000 MB/sec
Difference: 3200 (5%)

Texel Rate

The Radeon HD 6770 1GB should be a lot (approximately 132%) better at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon HD 6770 1GB 36000 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 20500 (132%)

Pixel Rate

The Radeon HD 6770 1GB will be quite a bit (about 132%) more effective at FSAA than the Radeon HD 5670, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 6770 1GB 14400 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 8200 (132%)

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: Bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 potential to get to the max fill rate.
