AMD's Bobcat and Bulldozer

[JF-AMD]

Bulldozer is pretty much an optimized CMT. CMT's supposed to give you twice a core's performance for even greater die-size but AMD settled for greater die-saving but for 80% of a core's performance.. I'm just quoting the slides.

<totally rhetorical question, NOT real numbers>
Which would you rather have:
80% of the performance with 50% of the cost and 50% of the power consumption
100% of the performance with 120% of the cost and 120% of the power consumption
</end rhetorical question>

People keep seeing that 80% number and thinking that it is a compromise. What they don't understand is that by sharing components we are able to add more cores in the same die space and same power budget.

It is by no means 80% of today's performance.
