The Intel Core i7-4850HQ is a high-end mobile processor launched in April 2013, sitting near the top of the Haswell Crystalwell hierarchy. Designed for premium gaming laptops and mobile workstations, it features four cores and eight threads, delivering formidable multitasking capabilities. Operating at a base frequency of 2.3 GHz and boosting up to 3.5 GHz, it provides excellent single-threaded performance for its generation. The inclusion of Intel HD Graphics 5200, backed by 128MB of L4 eDRAM, ensures that graphical workloads are handled with unprecedented efficiency for an integrated solution. This makes the chip highly versatile, capable of driving high-resolution displays and handling moderate 3D rendering without a dedicated GPU. With a 47-watt TDP, it requires a robust cooling solution but delivers desktop-class performance in a mobile footprint. Although end-of-life, the 4850HQ was a premier choice for power users demanding a balance of raw speed and graphical fidelity.
The Core i7-4850HQ is a high-end Crystalwell chip offering a 2.3GHz base and 3.5GHz turbo.
With 128MB of eDRAM boosting the Iris Pro 5200 graphics, it handles 1080p gaming and rendering well. It was a top choice for premium 2013 laptops.

Architecture Overview
The Core i7-4850HQ leverages the 22-nanometer Haswell microarchitecture, heavily modified into the Crystalwell design to accommodate integrated eDRAM. The package houses 1.4 billion transistors on a 264 mm² die, alongside a dedicated 128MB L4 eDRAM cache. This eDRAM provides massive bandwidth directly to the Intel HD Graphics 5200, overcoming the traditional memory bottleneck of integrated GPUs and enabling smooth 1080p gaming. The CPU cores share 6MB of L3 cache and connect to the system via the BGA 1364 socket. It supports dual-channel DDR3-1600 memory and provides 16 PCIe 3.0 lanes for discrete GPU pairings or high-speed NVMe storage. The 47-watt TDP is managed by advanced power gating, dynamically shifting power between the CPU cores and the integrated graphics array depending on the workload. This architecture ensures that whether the user is running a CPU-intensive compilation or a GPU-heavy render, the processor can route power efficiently to maximize performance.

History
The Core i7-4850HQ launched in April 2013 as one of the initial flagships of the Crystalwell mobile family. It was specifically engineered for the premium laptop market, targeting users who required workstation-class performance in a portable form factor. The integration of 128MB of eDRAM was a revolutionary step, allowing Intel to boast performance metrics that rivalled entry-level discrete graphics cards.
This chip found its way into high-end configurations of the MacBook Pro and top-tier Windows gaming laptops, where it often worked in tandem with dedicated GPUs via NVIDIA Optimus. The 4850HQ represented a golden era for mobile computing, where thermal envelopes allowed for aggressive turbo boosting and raw quad-core power. As Intel moved toward 14nm process nodes, the 4850HQ was eventually retired, but its legacy lives on as a pioneer of high-bandwidth cache architectures, a concept that would later be resurrected in modern server and gaming processors to bypass memory limitations.
Improvements over Previous Generation

Should You Buy It?
Not Recommended for the right buyer
If you are sourcing an Intel Core i7-4850HQ today, it is likely for repairing a vintage premium laptop, such as a 2013 MacBook Pro. The processor is end-of-life, but its 3.5 GHz turbo and HD 5200 graphics still pack a punch for retro gaming and 1080p media editing. When evaluating a system with this chip, pay close attention to the thermal paste and fan condition; a 47W Haswell chip will throttle heavily if overheating. If you are performing a BGA replacement, ensure your soldering profile matches the 1364 ball grid array. For general consumers, do not purchase a laptop with this CPU as a primary machine. Modern budget processors offer vastly superior battery life and single-core performance. However, if you need a cheap, capable machine for running older creative software or acting as a localized media server, a functional 4850HQ system can still provide excellent value at the right price.
