AMD Radeon HD 7970 benchmarks leaked

Techpowerup.com has spotted some interesting leaked documents along with archived documents saved in the MyDrivers community which suggest that AMD’s forthcoming flagship single GPU high-end graphics card will overclock like a beast and deliver some impressive performance figures.

Sapphire already has a card that will ship clocked at 1.33GHz on the core and 5.73GHz on the memory.

Sapphire appears to be planning as many as six non-reference Radeon HD 6970 cards. These will include water-cooled as well as air-cooled cards, and a variety of cards shipping with various non-stock clock speeds.

One overclocker with early access to the card has managed to overclock an HD 7970 to 1700MHz on the core and 8GHz on the memory. These speeds were achieved using liquid nitrogen and equated to a total memory bandwidth of 384 GB/s. More impressive is that the card was stable enough at these speeds to run 3D Mark 11 and 3D Mark Vantage to completion. The card managed to deliver scores of P54725 and P15063 respectively.

This is not the first time we have seen leaked information regarding AMD’s next generation of graphics cards. According to a document which turned up on the overclock.net forums last week, there will be as many as 11 reference model HD 7000 cards, ranging from the dual-GPU HD 7990 which will ship in March and cost $849 (R7,200), to the HD 7750 which should arrive next month and cost just $139 (R1,180).
