Hardware site The Upgrade Center claims to have seen a final sample of AMD's K7 microprocessor. According to Chris Harrison, the information he has is reliable. The sample is a final release piece graded at 550MHz with half speed cache. It booted at 650MHz but was not stable when the cache was enabled, and is about 25 per cent faster at Lightwave than a similar speed Intel Pentium III chip. It has a front side bus (FSB) setting of 100-250MHz, with 2x-8x multipliers. ®
