|Sapphire HD 7770 OC Series clocked at 1150MHz
Sapphire has also launched its HD 7700 series graphics cards, including two HD 7770 and a single HD 7750 graphics card.
As we already covered basic specifications of the 28nm GCN Cape Verde GPU, we will stick to Sapphire models. The launched HD 7750 is as basic as it could be but still features a custom fan that we already had a chance to see on couple of mid-range cards launched by Sapphire. Suprisingly, Sapphire used a green PCB on the HD 7750 and card stayed at 800MHz clock for the GPU and comes with 1GB of GDDR5 memory clocked at 4500MHz and paired up with a 128-bit memory interface.
More interesting are two Sapphire HD 7770 graphics cards, especially the OC Edition. While both use the same blue PCB and the same dual slot cooler with single center placed fan, the OC Edition works at 1150MHz for the GPU and 5000MHz for the same 1GB of GDDR5 memory. The reference one, of course, ended up at 1GHz for the GPU and 4500MHz for the same amount of memory.
Currently, the Sapphire HD 7770 OC Edition is just €10 more expensive than the reference clocked one, which makes it one of the most interesting HD 7770 cards on the market.
