GeForce GTX 570 vs Radeon HD 7950 3GB
Intro
The GeForce GTX 570 makes use of a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 RAM runs at a speed of 950 MHz on this particular model. It features 480 SPUs along with 60 Texture Address Units and 40 Rasterization Operator Units.Compare that to the Radeon HD 7950 3GB, which has a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 in one second. This number is worked out by multiplying the total 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 applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
Comments
One Response 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.
