AMD sales will fall 15 per cent sequentially from Q2 to Q3 - and flash memory is largely to blame, the company said to day.

In previous guidance for the quarter, AMD said that sales would fall 10-15 per cent to the quarter.

Sales of flash memory, for so long the AMD milch cow, are still expected to sink 30 per cent, panning out to a whopping $100m fall in revenue in Q3.

So we guess this means that processor revenues are not performing quite as well as AMD had hoped. The company says that unit sales in Q3 will "remain at or near the record level of the second quarter, when AMD sold 7.8 million units".

AMD's updated guidance was delivered by sales boss Rob Herb in presentation at Wit Soundview Semiconductor Conference in Santa Clara, California, the homeland of mortal enemy Intel.
