Radeon HD 5670 vs Radeon HD 6450 (OEM)
Intro
The Radeon HD 5670 features a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 6450 (OEM), which comes with GPU core speed of 625 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This number 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 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 record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

2 Responses to “Radeon HD 5670 vs Radeon HD 6450 (OEM)”i've ati radeon hd 6450 in my pc
and im going to replace it with ati hd 5670 will it support because my ram is 2 GB (DDR2)
and my graphic card is ddr3
but this 5670 is ddr5 will it run perfectly ??
can u please mail me yes or no with some explanation 🙂
thank you very much in advance
Mine is ASUS eah5670, it comes with an added feature of extended card life span. Probably upto 25%.
And i must say it is a beast. Gorgeous graphics, smooth performance and in comparison to other beastly cards it is but highly power efficient. I wud most definitely rank 5670 above 6450 without further hesitation. At such price range getting a card as such 5670 is quite tough and a challenge
