CPU Comparison
Intel Core i7-950 vs Intel Core i7-965
A side-by-side comparison of specs, performance and value. Launched in June 2009, the Intel Core i7-950 was a welcome refresh to the Bloomfield lineup, effectively replacing the i7-940. By increasing the base clock to 3.06GHz and turbo boost to 3.33GHz, Intel provided a more compelling mainstream option for the LGA 1366 platform. This four-core, eight-thread processor retained the 45nm manufacturing process and 8MB of L3 cache. The higher stock frequencies made it noticeably faster out of the box than the legendary i7-920, requiring less aggressive overclocking to achieve high performance. It quickly became a popular choice for high-end gaming rigs and workstations, offering a good balance of price and capability. While it still carried a 130W TDP, the i7-950 solidified the Nehalem architecture's presence in the market until the 32nm Gulftown chips arrived. It is remembered as a reliable, high-performance workhorse for its era.
