Performance Compared

Productivity

Intel Core i5-67017

Slightly better single-threaded performance than other Clarkdales, but still completely inadequate for modern productivity.

Intel Core i5-750Best25

Four cores help with basic multitasking but modern productivity apps will feel sluggish.

Gaming

Intel Core i5-6705

Even with high clock speeds, the dual-core design cannot run modern games.

Intel Core i5-750Best12

With a discrete GPU, can handle older games but cannot run modern titles at acceptable frame rates due to CPU limitations.

Virtualization

Intel Core i5-67011

Two cores with Hyper-Threading are insufficient for meaningful virtualization.

Intel Core i5-750Best20

Four real cores provide usable virtualization for lightweight VMs.

Efficiency

Intel Core i5-670Best30

73W for a dual-core is acceptable for the era but poor by modern standards.

Intel Core i5-75025

95W for four 45nm cores is inefficient by modern standards.

Our Verdict on Each

At $284, the i5-670 was paradoxically more expensive than the quad-core i5-750 while offering inferior multi-threaded performance. A poor value even at launch.

Best for: Collecting unusual Intel processor SKUs
