•500 ATI Radeon™ HD 5970 graphics cards - each with 2.7 TeraFLOPS of processing power

That should read each with 4.64 TeraFLOPS of processing power

Each 5970 contains two Cypress GPUs each running at 725MHz each of which has 2.32 TeraFLOPS of processing power (SP) or 464 GigaFLOPS (DP). That yields a FRC server with 2.32 PetaFLOPs (SP) of processing power from the GPUs. I think they confused the 5970 with the 5870 which runs at 850MHz and gets 2.72 TeraFLOPS SP and 544 GigaFLOPS DP.

The 250 61xx class CPUs are 12 core MCs with up to 2.3GHz clocks means 3000 cores. Thus 250 12 core CPUs at 2.3GHz means 27.6 TeraFLOPS of DP and 55.2 TeraFLOPS of SP which would make a top end FRC server have 2.38 PetaFLOPS of SP or 0.492 PetaFLOPS of DP processing power.
