Sapphire har efter hånden en hel del fabriks overclockede grafikkort på programmet, og dette Sapphire HD 7870 OC Edition vs XFX R7870 Black Edition er ingen undtagelse. Det er monteret med en kraftigere køler, og mon ikke der kan presses yderligere MHz ud af det?

When AMD launched their 7800 series at the beginning of the month they pretty much caught everyone by surprise. Partners (and journalists) initially thought they had more time to prepare but for various reasons, whether it be Cebit approaching which might see leaks, or because AMD felt confident in their product the launch was set for the first day of the show.

This meant that all initial reviews were of reference cards and the products on show at Cebit were either dummy cards or in the case of Sapphire the products were flown in on the first day and hand delivered to the stand.

Now though we are starting to see a steady stream of custom and overclocked 7870 cards hitting the street, and our test bench, so today we will put two of the top models, Sapphires OverClock Edition and XFX's DD Black Edition head to head in order to find out what they offer mainstream gamers looking for top performance in the latest games...including Mass Effect 3, Battlefield 3 and Skyrim.
