Compare any two graphics cards:
Radeon HD 6570 (OEM) 2GB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 6570 (OEM) 2GB uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the Radeon HD 6670 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this card. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be much (approximately 23%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 6670 (OEM) 1GB is a better choice, by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 this number, the better the video card will be at handling 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

3 Responses to “Radeon HD 6570 (OEM) 2GB vs Radeon HD 6670 (OEM) 1GB”The HD 6570 (2GB) has 2024 MB Memory of course 🙂
o really??? ithought it was something else
I believe he meant 2048 MB, good job both MPW and Retard.
