The Intel Core i7-5700HQ is a fast quad-core processor based on the Broadwell architecture, which has been launched in June 2015. In addition to four CPU cores with Hyper-Threading clocked at 2.7 - 3.5 GHz (2/3/4 Cores: 3.5 GHz as well), the chip also integrates an HD Graphics 5600 GPU and a dual-channel LPDDR3-/DDR3L-1866 memory controller. The Core i7 is manufactured in a 14 nm process with FinFET transistors.
Architecture
Broadwell represents the "Tick" in Intel's Tick-Tock model, which means a shrink of its predecessor Haswell. The new 14 nm manufacturing process with three-dimensional FinFET transistors allows not only improvements in energy efficiency, but also a significantly smaller die size fit for more compact packages and devices.
Further advantages result from the revised microarchitecture of Broadwell. Due to its improved branch prediction, bigger buffer sizes (1500 instead of 1000 entries in the L2 TLB) and other tweaks, the performance per clock has been increased by more than 5 percent over its predecessor. There are also some new instruction set extensions designed for cryptographic applications.
Performance
Thanks to its improved architecture and the advanced process node (lower power consumption leads to a better utilization of the Turbo Boost), the Core i7-5700HQ offers a performance similar to the Haswell-based Core i7-4900MQ (2.8 - 3.8 GHz). Thus, the CPU has sufficient power for demanding applications, modern games and intense multitasking.
Graphics
The integrated HD Graphics 5600 offers 24 Execution Units (EUs) clocked at 300 - 1050 MHz. Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock. The HD Graphics 5600 beats the previous HD Graphics 4600 (20 EUs) by about 20 percent, but is still significantly slower than dedicated low-end GPUs like the GeForce 920M. Most games as of 2015 will be playable only in (very) low settings.
Broadwell is the first Intel chip to fully support DirectX 11.2 as well as OpenCL 1.3/2.0 and OpenGL 4.3. Video will output natively via DisplayPort 1.2 or HDMI 1.4a. However, the new HDMI 2.0 standard is not supported.
Power Consumption
The i7-5700HQ is rated at a TDP of 47 W including the graphics card, memory controller and VRMs. Thus, the CPU is best suited for laptops 15-inches or greater. If necessary, the TDP can be lowered to 37 W (cTDP down).
