Review: The first 45nm Dual Core overclocks great


(This review is also available in German)

Last year we had the opportunity to review the first 45nm CPU. While a quad-core is not to everyone's taste, we're now taking a look at the first 45nm dual-core CPU, which is now available for purchase in limited quantities.

Besides the new SSE4.1 instruction sets, which are currently only used in some raytracing-applications, the most important feature is the new power-saving technology and, of course, the 45nm manufacturing process.

Image


Some motherboards displayed the CPU VCore at 1.1875V, while some showed 1.2250V, so we are not sure which is the correct value. Due to its new power-savings function this isn't really important. Before you buy an E8x00 CPU, make sure that you update your motherboard with the latest BIOS. The TDP is specified at 65W, which is a massive overstatment, as the CPU runs very cool and draws very little power, even when overclocked.

The only negative argument for this CPU is the cooler that comes with the retail boxed processors, as it is now manufactured using more plastic. If you lock the push pins the wrong way, they will become deformed. If you want to change the push pins it's likely that the plastic mounting will break loose rendering the cooler useless. In our opinion you should dispose of this cooler. The funny thing is that currently buying a tray CPU is more expensive, and as such you'll save some money buying the boxed one.
