With AMD's Quad FX processors recently launched with the ability to run a pair of dual-core CPUs, Intel has unveiled its next step to strengthen its hold on the market. At CES 2007, the silicon giant announced a proof-of-concept PC designed to counter AMD's 4x4 systems, named the V8. The system contains a pair of quad-core processors running at 2.4GHz using a 1066MHz system bus - when paired with an NVIDIA 8800GTX it manages to score 6089 on the 3Dmark06 CPU benchmark. However, it isn't all good news for Intel fans. The V8 system requires FB-DIMMs and only works with a single GPU at present, whilst Quad FX systems can use standard unbuffered memory along with multiple GPUs. If Intel doesn't manage to solve the problem with multi GPU support soon this may give AMD time to release 8x8 systems, which wouldn't be part of Intel's plan.
