PHENOM II X4 and Dragon platform

We tested the Phenom 940 and Phenom X4 II 920 II X4 AMD, characterized by the new 45-nanometer production process and architectural innovations. Great price, performance and fuel economy improved to normal, make it a very interesting proposal.

Phenom II and Dragon platform

It's been a long time since AMD has launched a convincing offensive against Intel. The transition to 45 nanometers has taken much longer than expected, but along with a new CPU, AMD today also presents a new technology.

Improvements are already visible by counting the number of transistors. The Phenom II consists of approximately 758 million transistors, 308 million more than the first revision. As with the first Phenom, the second version is compatible with all Socket AM2 motherboards. This allows the Phenom II offered as an alternative upgrade.

The company's flagship product, the Phenom X4 II 940, running at 3 GHz Phenom faster, the X4 9950 Black Edition, is set to operate at 2.6 GHz by default, with a narrow margin for overclocking. The Phenom II does not know this limit: even with a 3 GHz clock pulse, can reach speeds much higher.

AMD has introduced its first 45 nm processor already a few weeks ago, the Opteron models for server applications, products that occupy a much larger market share than the desktop. Meanwhile, the yield to 45 nm is grown to allow AMD to present the desktop models. With the new design of the core (codenamed "Deneb"), AMD has not only played a maneuver of die-shrink, but has also achieved dramatic improvements in energy consumption.

Since the first generation of Phenom (along with the Spider platform), even graphics cards have made strides. The new platform, which will replace Spider, will be based on a Phenom II paired with a Radeon HD 4800, and will be called Dragon.

The first series Phenom quickly reach their limits of performance due to high energy consumption. From 65 to 45 nm, the energy consumption decreases very individual transistors. To bring the Phenom 2.5 GHz to 2.6 GHz, AMD was also forced to raise the TDP, from 125 to 140 watts. This was enough to prevent the use of faster Phenom AM2 motherboard with many, precisely because of the energy requirement. The 45 nm technology, allows Phenom II to be better, and in many areas. This is the baseline: in terms of speed, power consumption and overcloccabilità, AMD has taken a big step forward compared to the first-generation Phenom.
