Performance Compared

Productivity

Intel Core i5-65015

Extremely slow by modern standards for any productivity application.

Intel Core i5-670Best17

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

Gaming

Intel Core i5-6505

Cannot run modern games at playable frame rates. Only suitable for pre-2010 titles.

Intel Core i5-6705

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

Virtualization

Intel Core i5-65010

Two cores with Hyper-Threading offer minimal utility for virtualization.

Intel Core i5-670Best11

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

Efficiency

Intel Core i5-65030

73W TDP for two cores is poor efficiency compared to modern chips.

Intel Core i5-67030

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

Our Verdict on Each

A historically significant processor that introduced 32nm manufacturing to desktops, but completely obsolete for any modern workload.

Best for: Keeping an existing LGA 1156 system running for basic tasks

Read the full review

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
