CPU Comparison
Intel Core i7-4770K vs Core i7-4820K
A side-by-side comparison of specs, performance and value. The Intel Core i7-4770K is an unlocked desktop processor launched in June 2013 as the flagship of the 4th Generation Haswell family. Built on the 22nm process, it features 4 cores and 8 threads, operating at a base clock of 3.5 GHz and boosting up to 3.9 GHz. The 'K' suffix denotes an unlocked multiplier, making it a favorite among overclocking enthusiasts. It includes 8MB of L3 cache and supports dual-channel DDR3 memory. With an 84W TDP, it fits into the LGA 1150 socket. The processor integrates Intel HD Graphics 4600, which can also be overclocked. While it was a top-tier gaming CPU in its era, the 4770K gained notoriety for running hot due to Intel's use of poor thermal paste under the integrated heat spreader (IHS), limiting extreme overclocking. Despite this, it remains a legendary chip that provided immense performance for gamers and enthusiasts before being superseded by the i7-4790K.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Okay for basic tasks, but slow for modern rendering.
Quad-channel memory helps with heavy multitasking.
Gaming
Bottlenecks modern GPUs significantly.
Still decent for 1080p gaming if overclocked, but lacks modern single-core speed.
Virtualization
Limited by 4 cores.
Excellent due to VT-d and 40 PCIe lanes.
Efficiency
84W TDP is inefficient by modern standards.
130W TDP for a quad-core is highly inefficient by modern standards.

Our Verdict on Each
A legendary overclocking CPU that brought great performance, but its thermal issues and age make it obsolete today.
Best for: The Core i7-4770K is a legendary processor that should only be considered today if you are maintaining an existing LGA 1150 system. It still offers decent performance for basic computing and older games, and its unlocked multiplier allows for some overclocking fun if you have adequate cooling. However, it is not recommended for new builds. The lack of Windows 11 support, high power consumption, and outdated instruction sets make it a poor choice for modern workloads. If you are building a budget PC, modern processors like the Intel Core i3-12100F offer vastly superior performance, efficiency, and an upgrade path. Avoid buying this CPU unless it is nearly free and you need to keep an old system running.
