HKEPC claims AMD will soon open the CrossFire technology so a 3rd party chipset maker will be able to make CrossFire compatible chipsets.
CrossFire support in Intel P965 and 975X are just the very exceptional cases, and there is no 3rd party chipset are allowed to use these features. It’s not technical issue that makes other company unable to design, but the authorization problem.
While the market was wondering if AMD would still allow Intel to support CrossFire in the future, AMD recently plans to open the CrossFire architecture to 3rd party chipset, so called Open Multi-GPU Chipset Platform. As of this drafting stage, it’s told that for any chipset which boast two 16x PCI-E slots, CrossFire is already granted to be enabled. Therefore, not only Intel, VIA, SIS, and even NVIDIA’s chipset may able to support CrossFire, resulting in pushing the market share of CrossFire.
