Radeon HD 5750 1GB vs Radeon HD 5770

Intro

The Radeon HD 5750 1GB comes with core speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 5770, which features a core clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 128-bit bus, and uses a 40 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB 86 Watts
Radeon HD 5770 108 Watts
Difference: 22 Watts (26%)

Memory Bandwidth

Theoretically, the Radeon HD 5770 should be just a bit faster than the Radeon HD 5750 1GB overall. (explain)

Radeon HD 5770 76800 MB/sec
Radeon HD 5750 1GB 73600 MB/sec
Difference: 3200 (4%)

Texel Rate

The Radeon HD 5770 should be quite a bit (about 35%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon HD 5770 34000 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 8800 (35%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 5770 is superior to the Radeon HD 5750 1GB, and very much so. (explain)

Radeon HD 5770 13600 Mpixels/sec
Radeon HD 5750 1GB 11200 Mpixels/sec
Difference: 2400 (21%)

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 max amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
