Performance Compared

Productivity

Intel Core i5-650040

Lacks the thread count for modern multi-tasking and rendering workloads.

Intel Core i3-12100Best65

Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.

Gaming

Intel Core i5-650055

Bottlenecks modern GPUs heavily in newer titles; fine for older or esports games.

Intel Core i3-12100Best65

Delivers playable 1080p frame rates in esports and older AAA titles when paired with a mid-range GPU, though 4 cores limit performance in modern CPU-heavy games.

Virtualization

Intel Core i5-650030

Very limited for running VMs due to 4 threads.

Intel Core i3-12100Best45

Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.

Efficiency

Intel Core i5-650070

65W TDP is easy to cool and fairly efficient for a 14nm quad-core.

Intel Core i3-12100Best82

Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.

Our Verdict on Each

A reliable workhorse in its day, the i5-6500 delivered excellent value for locked mainstream builds, though its 4-thread limitation renders it obsolete for modern heavy workloads.

Best for: The i5-6500 is only viable today if you are repairing an older LGA 1151 system on an extreme budget or building a basic home server. It can handle web browsing, office applications, and retro or esports gaming adequately. However, buying one new or even used at a high price makes no sense. Modern entry-level chips like the i3-12100F obliterate it in single-core and multi-core performance while offering a modern platform with an upgrade path. If you already own this chip, keep it as long as your tasks remain basic, but do not invest money into this platform expecting a noticeable uplift over your existing setup without moving to a newer generation.

Read the full review

The i3-12100 delivers exceptional single-threaded performance for its $122 price point, complete with an iGPU and a stock cooler, making it one of the most well-rounded budget desktop processors Intel has ever produced.

Best for: Buy the i3-12100 if you are building a budget desktop PC and want the peace of mind of having integrated graphics as a fallback, or if you do not plan to install a dedicated GPU. At its current street price, it is an excellent choice for office PCs, student workstations, and entry-level gaming rigs paired with a mid-range graphics card like the GTX 1660 Super or RX 6600. Avoid it only if you are certain you will never need the iGPU, as the 12100F offers identical CPU performance for less money.
