Radeon HD 5670 vs Radeon HD 5770


Intro

The Radeon HD 5670 comes with core speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Compare all of that to the Radeon HD 5770, which has a GPU core clock speed of 850 MHz, and 1024 MB of GDDR5 RAM set to run at 1200 MHz through a 128-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5670 61 Watts
Radeon HD 5770 108 Watts
Difference: 47 Watts (77%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5770 should be 20% faster than the Radeon HD 5670 overall, because of its greater bandwidth. (explain)

Radeon HD 5770 76800 MB/sec
Radeon HD 5670 64000 MB/sec
Difference: 12800 (20%)

Texel Rate

The Radeon HD 5770 should be a lot (approximately 119%) better at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon HD 5770 34000 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 18500 (119%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 5770 is superior to the Radeon HD 5670, and very much so. (explain)

Radeon HD 5770 13600 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 7400 (119%)

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 moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. 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 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.
