AMD Athlon 64 Processors on E Core: Memory Controller Peculiarities in Detail
 

The E core revision of the AMD Athlon 64 processors features an enhanced integrated memory controller. In our today’s article we will discuss what has been improved compared with the previous controller version, namely, how the new Athlon 64 CPUs work with four memory modules and what benefits the DDR500 SDRAM support has brought these processors. Find out all the exciting details now

Not so long ago AMD64 processor family with new E core revision appeared in the market. This processor core manufactured with 90nm process using SOI (Silicon on Insulator) and DSL (Dual Stress Liner) technologies got into a few processor product lines. The new E core found its way into several application fields. You can see it in Athlon 64 and Athlon 64 FX processors, where it is known under Venice and San Diego code names, as well as in dual-core Athlon 64 X2 processors, where it is known as Toledo or Manchester. It is also used in AMD Sempron processors where they call it Palermo.


When AMD develops and puts into mass production new processor cores, it aims not only at increasing the working frequencies of their new processors based on these cores, but also at improving their features and specifications. The E core revision appeared another threshold on this way: it provided Athlon 64 processors and their modifications with a number of absolutely new features. One of the most significant enhancements appeared the support of new SSE3 instructions, which has been already implemented in the competitor’s solutions since the 90nm Prescott core. Moreover, the integrated memory controller also underwent a few noticeable enhancements
