Performance Compared

Productivity

Intel Core i5-65015

Extremely slow by modern standards for any productivity application.

Intel Core i5-680Best18

Best single-threaded performance in Clarkdale but still insufficient for modern productivity.

Gaming

Intel Core i5-6505

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

Intel Core i5-680Best6

High clock speed helps slightly but the dual-core design remains a fundamental barrier.

Virtualization

Intel Core i5-65010

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

Intel Core i5-680Best12

Two cores with Hyper-Threading remain inadequate.

Efficiency

Intel Core i5-65030

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

Intel Core i5-680Best32

73W for 3.6GHz on 32nm was reasonable for 2010 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

The fastest Clarkdale ever made, but at $294 for two cores, it was a tough sell against the i5-750. Now entirely obsolete.

Best for: Completing a Clarkdale collection or keeping an existing system running
