AMD Athlon X2 4850e

In addition to releasing the low-power 55nm RS780 chipset AMD has also brought forward another energy efficient pile 'o transistors under the name of Athlon X2 4850e. The new dual-core CPU is based on the Brisbane core, manufactured using the 65nm process and it is clocked at 2.5 GHz.

Equipped with 1MB of L2 cache the X2 4850e has a TDP of just 45W and will hit the stores soon at prices around $89. The processor is be based on 65 nm core stepping G2 - stamped ADH4850IAA5DO. Each of two cores is equipped with 512 KB cache in the second level, TDP level does not exceed 45 W. The chip's predecessor, the dual-core Athlon X2 4800 came with a thermal power design of 65 watts. However, AMD's newest dual-core offering, the 4850E packs identical specifications as the 4800, while consuming less power. The default specifications for the two processors are a default clock speed of 2.5 GHz, 1MB of total dedicated L2 cache and a 2000-MHz HyperTransport bus.

While we won't cover it in the article, the processor is quite an overclocker .. we overclocked this to roughly 3 GHz by increasing the stock voltage on the 780G chipset, so this chipset is also an excellent overclocker.

Granted, usually I'm not the one to get excited about budget integrated mainboards. But at the CeBIT AMD announced their 780G chipset, and for the first time in history I was pretty excited about the technology. In addition to releasing the low-power 55nm RS780 chipset AMD has also brought forward another energy efficient pile 'o transistors under the name of Athlon X2 4850e. We'll take a look at that one as well.
