The Intel Core i7-4771 is a desktop processor launched in September 2013 as a minor refresh within the 4th Generation Haswell family. Designed for the LGA 1150 socket, it features 4 cores and 8 threads, operating at a base clock of 3.5 GHz and boosting up to 3.9 GHz. Built on the 22nm process, it includes 8MB of L3 cache and supports dual-channel DDR3 memory. With an 84W TDP, it offers identical performance to the i7-4770K but lacks an unlocked multiplier, meaning it cannot be overclocked via the CPU ratio. It integrates Intel HD Graphics 4600 for basic display tasks. The i7-4771 was essentially an OEM-focused or slightly repackaged alternative to the 4770, offering high-end computing power for pre-built systems and standard desktop users. While it has been succeeded by many generations, it remains a capable chip for legacy computing and basic productivity.
Launched in 2013, the Intel Core i7-4771 is a Haswell desktop processor featuring 4 cores, 8 threads, and a max turbo of 3.9 GHz. It matches the i7-4770K in stock performance but has a locked multiplier.
It is suitable for legacy desktop tasks but is outdated for modern workloads.

Architecture Overview
The Core i7-4771 utilizes the Haswell microarchitecture, manufactured on Intel's 22nm process. It features 4 physical cores with Hyper-Threading, allowing 8 concurrent threads. The architecture introduced AVX2, which doubled the throughput of integer operations, and TSX for improved multi-threaded performance. The integrated memory controller supports dual-channel DDR3 memory up to 1600 MT/s. For graphics, it relies on Intel HD Graphics 4600, which features 20 execution units. Haswell also introduced a more advanced power management system, allowing the processor to transition between power states more quickly. The architecture routes 16 PCIe 3.0 lanes directly from the CPU. Unlike the 4770K, the 4771 has a locked multiplier, preventing CPU ratio overclocking. This architecture was a key stepping stone in Intel's evolution toward highly efficient processors, bridging the gap between Ivy Bridge and Broadwell.

History
Launched on September 1, 2013, the Intel Core i7-4771 was a minor SKU refresh released a few months after the initial Haswell lineup. It was designed to offer the same out-of-the-box performance as the popular i7-4770K but without the unlocked multiplier, targeting users who didn't intend to overclock. The 4771 was primarily found in pre-built systems and standard desktop configurations.
During this period, Intel dominated the desktop CPU market, and the Haswell architecture provided excellent single-core performance that AMD's FX series couldn't match. The release of the 4771 helped fill out Intel's product stack, offering system builders a slightly different price-to-performance tier. Like the rest of the Haswell family, it was eventually superseded by the 'Devil's Canyon' refresh (i7-4790) in 2014, which offered higher clock speeds and improved thermal management.
Today, the 4771 is a relic of Intel's past dominance in the mainstream desktop market.
Improvements over Previous Generation

Alternatives & Competitors
Should You Buy It?
Not Recommended for the right buyer
The Core i7-4771 is a processor that should only be encountered in legacy systems. If you already own a motherboard with this chip, it can still serve adequately for basic web browsing, office applications, and older games. However, it is not recommended for purchase today. The LGA 1150 platform is dead, meaning there is no upgrade path. Additionally, the lack of official Windows 11 support and high 84W TDP make it inefficient compared to modern budget processors. Avoid buying this CPU for new builds. It is best utilized by keeping existing hardware alive for light duties or retro gaming.
Avoid if…
- Building a new PC
- Need Windows 11 support
- Want modern gaming performance
- Require high efficiency
