New 90nm Sempron Socket 754 processors already selling
Simultaneously with the price cut AMD expanded its processor list with new Semprons that replaced older value products. In Japan they already sell these novelties, including new Sempron 2600+, 2800+ and 3000+:
According to AMD processor roadmap (as the company haven´t disclosed anything about the new CPUs), these Semprons are based on 90nm Palermo core with SOI. Well, the value 90nm processors are not that hot news, as already last month they started selling 90nm Sempron 3100+ (SDA3100AIO3BA) and LV Mobile Sempron 2600+ (as for Mobile Sempron 2600+, 2800+ and 3000+, the official website states they are also based on 90nm process — the Georgetown core).
The new Semprons are encased into usual 754-pin mPGA packages implying the built-in single-channel memory controller. See the table below for model names and specs.

You can see that L2 cache differs as well as the clock rate ("BA" suffix speaks of 90nm process, while the preceding "2" or "3" means 128 or 256 KB L2). It´s interesting that 128KB L2 processors were packed just about a month ago unlike the 256KB L2 ones:
The transition to the new Palermo core (D0 stepping) doesn´t imply the addition of any fundmentally new features, but the 90nm process reduces the chip size which, in turn, reduces the cost price and allows to make faster CPUs in the future.
