A few benchmarks have been posted over at Coolaler forums in which a Nvidia GTX580 and HD6990 Graphics have been demonstrated on the recently leaked Ivy Bridge Dual Core Sample.

The Ivy bridge chip is the same which we reported earlier here, It runs at a stock clock of 1.8Ghz, Comes with 2C/4T and a 4Mb L3 Cache. The Ivy Bridge platform along with the graphic cards were benchmarked using Futuremark's 3D Mark Vantage. Following are the results:

Intel Ivy Bridge Sample @ 1.8Ghz, Radeon HD6990 @ 950/1400mhz:

CPU SCORE: 5805GPU SCORE: 21064Total Score: 12711 3DMarks

Intel Ivy Bridge Sample @ 1.8Ghz, GTX580 @ 920/1200/1860mhz:

(PHYSX ON)

(PHYSX OFF)

CPU SCORE: 6049GPU SCORE:0Total Score:0 3DMarksAs you may have noticed, Both cards are beingBottle-neckedby the tiny Dual Core chip. It would've been better if the OP overclocked the CPU instead of overclocking the GPU's. The CPU score with PhysX enabled is higher because the operations are handled by the GPU's PPU which is the reason why the GTX580 resulted in a higher score than the Radeon HD6990 which is twice as fast as the card.
