CPU Comparison
Core i7-4820K vs Core i7-4930K
A side-by-side comparison of specs, performance and value. The Intel Core i7-4820K is a high-end desktop (HEDT) processor based on the Ivy Bridge-E architecture, released in September 2013. Featuring 4 cores and 8 threads, it operates at a high base clock of 3.7 GHz and boosts up to 3.9 GHz. What sets this CPU apart is its unlocked multiplier, making it a favorite among enthusiasts. Built on a 22nm process, it utilizes the LGA 2011 socket and supports quad-channel DDR3 memory. Unlike mainstream Intel CPUs, the 4820K lacks integrated graphics, requiring a discrete GPU. It features 10MB of L3 cache and a 130W TDP. This processor was designed for users who wanted the platform benefits of the X79 chipset, such as more PCIe lanes and quad-channel memory, without paying for the 6-core or 8-core variants. It offered excellent overclocking potential and strong single-threaded performance for gaming and high-performance computing.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Quad-channel memory helps with heavy multitasking.
6 cores still handle modern productivity apps well.
Gaming
Still decent for 1080p gaming if overclocked, but lacks modern single-core speed.
Good for gaming, but single-core speed lags behind modern CPUs.
Virtualization
Excellent due to VT-d and 40 PCIe lanes.
Excellent for home labs and multiple VMs.
Efficiency
130W TDP for a quad-core is highly inefficient by modern standards.
130W TDP is high, and overclocking makes it worse.
