i7-5700HQ - 4C/8T Broadwell-H Mobile CPU up to 3.5GHz | Intel

The Intel Core i7-5700HQ is a 4-core, 8-thread mobile processor built on Intel's 14nm Broadwell-H architecture, launched in June 2015 at a $378 MSRP. It operates at a 2.70 GHz base clock with Intel Turbo Boost up to 3.50 GHz, integrates 6 MB of L3 cache, and is soldered onto the motherboard in a BGA-1364 package (also referenced as FCBGA-1364). The i7-5700HQ supports dual-channel DDR3L-1600 memory and is rated at a 47 W TDP, making it a mainstream performance CPU for 2015-era gaming and workstation notebooks. A mobile quad-core processor (HQ-class) is Intel's high-performance tier for laptops, sitting above U-series (ultrabook) and H-series dual-core parts. The Core i7 brand indicates Hyper-Threading, larger cache, and higher Turbo ceilings than Core i5/i3 siblings. Broadwell-H represents the 5th-generation Core microarchitecture, succeeding Haswell with a 14nm tri-gate process, an updated integrated Iris Pro 6200 GPU, and improved instruction-per-clock efficiency. These processors are soldered (BGA) and not user-upgradeable. Key features include 4 physical cores with Hyper-Threading for 8 logical threads, a 6 MB shared L3 cache, and a configurable TDP-down mode of 35 W for thermal-constrained chassis. The integrated Iris Pro 6200 graphics with 48 execution units and 128 MB of eDRAM (L4 cache) provides modest gaming capability and Quick Sync video acceleration. AVX2 and AES-NI instructions accelerate compute and cryptographic workloads. Architecturally, Broadwell-H pairs an updated out-of-order core with a ring interconnect to the System Agent, integrated memory controller, and GT3e-class graphics. The 14nm process allowed higher frequencies at the same 47 W envelope versus the 22nm Haswell predecessor, while the 128 MB eDRAM side-cache boosts both CPU and GPU bandwidth when working on data sets that fit inside it. Typical applications include 2015-2016 era gaming laptops, mobile workstations running CAD or video editing software, and high-performance ultrabooks where the 47 W TDP can be cooled. The quad-core/8-thread configuration suits multi-tasking, video encoding, and lightly threaded productivity. The integrated GPU also enables headless media transcode via Quick Sync. Design consideration: because this is a BGA-1364 soldered part, replacement requires motherboard-level rework. When sourcing refurbished laptops, verify the BIOS supports the i7-5700HQ stepping and pair with dual-channel DDR3L-1600 SODIMMs to avoid memory bandwidth bottlenecks to the integrated GPU.
