CPU Comparison
Core i7-860 vs Intel Core i5-750
A side-by-side comparison of specs, performance and value. The Intel Core i7-860 is a mainstream desktop processor launched in September 2009, based on the 45nm Lynnfield architecture. Operating at a base frequency of 2.8 GHz and boosting up to 3.466 GHz via Turbo Boost, it offered an excellent price-to-performance ratio for its time. It features 4 cores and 8 threads, supported by an 8 MB L3 cache. Utilizing the LGA 1156 socket, it brought the Nehalem microarchitecture to a wider audience. Unlike Bloomfield, Lynnfield integrates a dual-channel DDR3 memory controller and 16 PCIe 2.0 lanes directly on the CPU, reducing platform costs. It lacks an integrated GPU, requiring a discrete graphics card. With a 95W TDP, it was relatively easy to cool. The i7-860 became a highly popular choice for gamers and enthusiasts in 2009, offering near-920 performance at a lower price point. Today, it is obsolete but fondly remembered as a workhorse CPU that defined the early Core i7 era.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Still usable for basic tasks but lacks modern speed.
Four cores help with basic multitasking but modern productivity apps will feel sluggish.
Gaming
Handles old games well but bottlenecks modern titles.
With a discrete GPU, can handle older games but cannot run modern titles at acceptable frame rates due to CPU limitations.
Virtualization
Good for legacy home servers and VMs.
Four real cores provide usable virtualization for lightweight VMs.
Efficiency
95W TDP is acceptable for 45nm, but poor by modern standards.
95W for four 45nm cores is inefficient by modern standards.
Specialized Performance
AI / ML
- No AI hardware
- Unsuitable for modern inference
- No AI acceleration instructions
- Far too slow for any ML workload
Content Creation
Gaming
- PCIe 2.0 only
- No AVX support
- Requires discrete GPU
- 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
