GeForce GTX 570 vs Radeon HD 7950 3GB
Intro
The GeForce GTX 570 has a clock frequency of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also features a 320-bit memory bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.Compare those specifications to the Radeon HD 7950 3GB, which comes with a core clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

2 Responses to “GeForce GTX 570 vs Radeon HD 7950 3GB”I can only say for this case its best to get the 570 if you want to say cash.
But if you have the means I rather go for the 7970. Not very advisable in my books to get the 7950 at the price its being offered for what it can do.
i have a 7950 Asus i had the 570 but will never look back the 7950 kicks the 570
