If you take the ranges and divide by the number of skus, you get $72 for Intel and $8 for AMD. Nothing wrong with a lot of skus when you have significant product differentiation. When there isn't that much differentiation, you have higher carrying costs.
Look at Apple: they give you a limited number of choices in each product space.
i wonder if those distis have price protection even at those prices
When I was in the business, disti's that I worked with would post SKU's that were deeply discounted (I usually didn't touch them because of aging concerns with infrastructure) and were not offered for sale with return priviledges. If the disti wouldn't offer returns, chances were good they couldn't either. (From what I was told by one person at one disti this was true - ymmv).
