Benchmarks & Specs

Last updated:
The Intel Core 2 Extreme QX9650 once represented the absolute pinnacle of desktop processors. Manufactured under the Yorkfield architecture, it aimed for maximum computing power. The designation "Extreme" was no accident; this processor was specifically designed for gaming enthusiasts. It offered truly impressive computing power for its time.

We remember well its four cores, which were considered state-of-the-art back then. They reliably handled demanding tasks. Manufactured in the advanced 45-nm process, it benefited from improved efficiency. Its generous 12 MB L2 cache contributed significantly to the responsive performance. This enabled quick access to frequently needed data.

Development has progressed rapidly since then. But the QX9650 stands for an era of technological breakthroughs. It impressively showed what performance Intel could provide at the time. It was a high-end solution for users with no compromise on computing power.
