CPU Comparison

Intel Core i7-920 vs Intel Core i7-965

A side-by-side comparison of specs, performance and value. The Intel Core i7-920, launched in November 2008, is arguably the most legendary processor of the Nehalem generation. It brought the brand new LGA 1366 platform and Bloomfield architecture to the mainstream enthusiast market at an affordable price point. With four cores and eight threads, a base clock of 2.66GHz, and 8MB of L3 cache, it offered phenomenal performance for its era. More importantly, it featured an unlocked Base Clock (BCLK) overclocking mechanism, allowing users to push frequencies far beyond stock speeds, often reaching 3.8GHz or higher. This overclocking headroom made it a cult classic. Despite its 130W TDP, the i7-920 popularized Hyper-Threading and triple-channel DDR3 memory. It remained a staple in gaming rigs and workstations for years, earning a reputation as the best value CPU of its time and cementing Intel's dominance in the enthusiast segment.
