Radeon HD 5670 vs Radeon HD 6570 (OEM) 1GB

Intro

The Radeon HD 5670 comes with a GPU core speed of 775 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is comprised of 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which features a clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 1GB 50 Watts
Radeon HD 5670 61 Watts
Difference: 11 Watts (22%)

Memory Bandwidth

Performance-wise, the Radeon HD 5670 should in theory be quite a bit superior to the Radeon HD 6570 (OEM) 1GB overall. (explain)

Radeon HD 5670 64000 MB/sec
Radeon HD 6570 (OEM) 1GB 28800 MB/sec
Difference: 35200 (122%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be a bit (approximately 1%) more effective at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 100 (1%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5670 is superior to the Radeon HD 6570 (OEM) 1GB, but not by far. (explain)

Radeon HD 5670 6200 Mpixels/sec
Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
Difference: 1000 (19%)

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 moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it 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 AA, 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 amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling 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 write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
