Radeon HD 5670 vs Radeon HD 6450 (OEM)
Intro
The Radeon HD 5670 features a core clock frequency of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon HD 6450 (OEM), which features a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory set to run at 800 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that 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 number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability 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
