Nvidia’s Kepler architecture is very impressive, as it sometimes overtakes AMD’s Tahiti-based cards, despite AMD’s chip having 21% more transistors and a 50% wider memory BUS.
The rough power of AMD’s GCN
architecture is still a considerable advantage for the Texas-based fabless GPU designer.
In most GPU compute applications that don't have CUDA optimizations inside, AMD’s raw power shows huge performance advantage over Nvidia’s Kepler.
On the other hand, Kepler uses less power and a less complex PCB.
The 3D Mark11 E
score (Extreme Preset) record was achieved also by a Radeon HD 7970 card.
Now, Polish overclocking enthusiast Xtreme Addict reportedly
managed to achieve a score of P15745 points using an MSI Lightning Radeon HD 7970 video card overclocked to a high 1750 MHz.
So now, the record for highest 3DMark11 P score is also in AMD’s camp.
