Radeon HD 7950 vs Radeon HD 7970

Intro

The Radeon HD 7950 makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory works at a speed of 1250 MHz on this model. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 7970, which comes with a clock speed of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.

I thought that the HD 7950 had 3GB of memory...

exodus says:

it does..... silllyyyyy

Anon says:

There is a 3GB version of the 7950. It's a separate item on the lists displayed on this site.

Go to the top of the page, click the dropdown lists, select the 3GB version. Now that wasn't hard, was it?

Xnerdz says:

Yeah, I didn't saw it the first time... sorry, my bad.
