Benchmarks & Specs

Last updated:
The Intel Core 2 Extreme QX6700 was a standout processor from Intel in its time. Its "Extreme" name clearly signaled its specialization. It was specifically designed for enthusiastic users and demanding gamers. With its four processing cores, it offered then exceptional performance. Many modern applications benefited noticeably from this architecture.

This processor was based on the Kentsfield architecture and was manufactured using the advanced 65-nanometer process. Particularly noteworthy was the 8 MB Level 2 Cache. This large cache significantly accelerated data access. A maximum memory bandwidth of 17 GB/s also supported fast data processing.

The QX6700, as one of the first quad-core processors, set new standards. It clearly demonstrated what was possible with multi-core architectures. Its robust performance allowed for good work even over longer periods. It was an important step in the development of high-performance desktop systems. We fondly remember its innovative power.
