Below is what the Sapphire 7950 OC looks like in terms of details:

As you can see, the significant differences here from the previous generation, at least in terms of specifications, is the 3GB of GDDR5 memory instead of the usual 2GB, while the clock speeds have been bumped up to 900MHz on this particular Sapphire card from the stock 810MHz.

Of course, with a new architecture comes new performance improvements. And the 28nm process manufacturing should result in lower temperatures. Put all these factors together, and we should be looking at a very impressive card. Specs on paper are a whole different matter than what lies on the bench though, so let’s take a closer look at the card and then find out.
