Of course it is i7. i7 is a new architecture processor used to replace the Core 2 high-end quad-core.

QX9770 is a spliced ??quad-core, not a native quad-core. It is made by connecting two Core 2 dual-cores together with a front-side bus. The two dual-cores share a front-side bus and each share a second-level cache. In this way, when the data of the two dual-cores are different, the data must be propagated through the front-side bus to achieve balance. This often leads to data congestion on the front-side bus and serious data delays. Although the advanced architecture of the QX9770 makes up for this problem to a certain extent, the efficiency has been reduced after all, and the power consumption is very large. Similar problems also appeared on the previously eliminated Pentium D dual-core, but the Pentium D has two single cores connected by a front-side bus, while the QX9770 has two dual cores. The core of the QX9770 only has a computing unit and nothing else. It is a pure CPU. Therefore, it is not well coordinated with the motherboard and memory. It must be coordinated through the motherboard, which also increases the trouble of delay. Although the QX9770 scores quite high in various software tests, its multimedia capabilities and gaming performance have never been enhanced with the increase in CPU speed. AMD's Dragon II, which is also based on the 45nm architecture, although its score is not as good as the Q9770, its gaming performance is slightly better.

i7 is the newly released Nehalem architecture, a 32nm core, integrated with a memory controller and a 45nm GPU. Not only is the architecture more advanced than the QX9770, it is more precise and integrates more computing units, it can also It is well coordinated with the motherboard and has more powerful multimedia capabilities, reducing the burden on the motherboard. The Nehalem architecture i7 is a native quad-core, and the four cores are directly connected. There is no need to exchange data through the front-side bus, and there is no need to transmit it through the front-side bus. Therefore, the efficiency of the front-side bus is greatly enhanced, and there is no delay problem. There is not only a second-level cache, but also a third-level cache, which enhances the efficiency of the cache and reduces power consumption. The emergence of Nehalem has greatly improved Intel's multimedia capabilities, which have always been a headache.

Because of these advantages, the core burden of i7 is also reduced, so although the power consumption of i7 is not small, it is definitely lower than that of QX9770.
