Which 7970 is best

AMD will reveal more about those in due time, but as with the Evergreen and Northern Islands families AMD has a plan to introduce a number of video cards over the next year. So is just the beginning. Post Your Comment Please log in or sign up to comment. Privacy Policy. Contact Us.

Terms of Use. Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance. Newer versions can support more bandwidth and deliver better performance.

The graphics card contains two graphics processing units GPUs. This generally results in better performance than a similar, single-GPU graphics card. The graphics card uses a combination of water and air to reduce the temperature of the card. This allows it to be overclocked more, increasing performance.

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability. The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.

Performance 1. GPU clock speed MHz. The graphics processing unit GPU has a higher clock speed. Floating-point performance is a measurement of the raw processing power of the GPU. The number of pixels that can be rendered to the screen every second. GPU memory speed MHz. The memory clock speed is one aspect that determines the memory bandwidth.

The number of textured pixels that can be rendered to the screen every second. Shading units or stream processors are small processors within the graphics card that are responsible for processing different aspects of the image. GPU turbo Unknown.

AMD claims the core clock boost from MHz to 1GHz is due to better understanding of the manufacturing process and a few tweaks to that process. The system was not overclocked. All the game tests are reported at x pixel resolution with 4x multisampling antialiasing enabled. However, PowerTune Boost, the higher core clock speed, and the faster memory does come at a cost—while idle power is actually a little better than the original, at W versus W for the first Radeon HD , full load power is a whopping W, over 18 percent higher than the W maximum power draw on the original HD What this also means is that the card may be louder, depending on the cooling system design.

Given the right case and cooling system, though, noise can be mitigated somewhat.
