Almost a year ago we confirmed the existence of a native quad core without L3 cache codenamed Propus and today, we can finally tell you that you should see the first batch of them in very early Q2 2009.

According to AMD’s latest plans, the new CPU might be out at some point in April and we are talking about AMD's first quad cores with a 45W TDP. The fastest one, Athlon X4 605e, will run at 2.3GHz and will have a total of 2MB cache, 4x512KB per core.

The runner up is the Athlon X4 600e that will work at 2.2GHz and has the same specs. Three cores based on Rana, three core without L3 cache based on Propus design, will also follow in roughly the same schedule.

Before these 45W CPUs, the best that AMD could come up with in 45W area was the 2.6GHz Athlon X2 5050e based on the good old Brisbane 65nm core and we are sure that the 2.3GHz Athlon X4 605e can make it worth a while at the same thermal power.
