CPU Comparison
Intel Core i7-950 vs Intel Core i5-750
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.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 threads help, but low IPC limits modern productivity.
Four cores help with basic multitasking but modern productivity apps will feel sluggish.
Gaming
Higher clocks help slightly over the 920, but still bottlenecks modern games.
With a discrete GPU, can handle older games but cannot run modern titles at acceptable frame rates due to CPU limitations.
Virtualization
Good for basic VMs and legacy server setups.
Four real cores provide usable virtualization for lightweight VMs.
Efficiency
130W TDP is highly inefficient for a quad-core.
95W for four 45nm cores is inefficient by modern standards.
Specialized Performance
AI / ML
- Incompatible with modern AI workloads
- No AI acceleration instructions
- Far too slow for any ML workload
Content Creation
Gaming
- Low IPC
- No AVX2
- Bottlenecks modern titles
- Cannot run modern AAA games at playable frame rates
- With a capable discrete GPU, older titles (pre-2015) run adequately
- The 2.666GHz base clock is a significant bottleneck

Our Verdict on Each
A solid refresh that offered great out-of-the-box performance for LGA 1366. Obsolete today, but a reliable chip in its time.
Best for: Cheap drop-in upgrade for an old LGA 1366 system coming from an i7-920.
Read the full reviewA landmark processor that offered excellent quad-core value in 2009-2010. Completely obsolete today but historically significant as the processor that established the Core i5 brand.
Best for: Keeping an existing LGA 1156 Lynnfield system functional for light tasks
