If you are after an AMD quad core that will fit the 45W thermal envelope, we have some good news for you. In early Q2 the company will launch the Athlon X4 605e at 2.5GHz with 2MB cache that will fit the 65W TDP. This CPU is based on Propus, K10.5 without L3 cache and of course in AM3.

By the middle of Q2 2009 AMD will launch another Athlon X4 branded 6xxe, and this CPU will run somewhere between 2.1Ghz and 2.4GHz and it will be based on the same Propus core. This will be the first 45W quad core and many will go after it. There is a good chance that this one might be a good overclockers, but traditionally 45W CPUs are much cooler than the 65W+ ones.

A 45W TDP is usually a virtue of dual cores and in January, Intel will introduce its 45W quad cores, as it looks that there is a market for such products.
