Intel Core i7-5750HQ vs Intel Core i7-5557U
Intel Core i7-5750HQ
► remove from comparison
The Intel Core i7-5750HQ 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 2.5 - 3.4 GHz (2/3/4 Cores: 3.4 GHz as well), the chip also integrates an Iris Pro Graphics 6200 GPU with on-package eDRAM and a dual-channel LPDDR3-1866/DDR3L-1600 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, the Core i7-5750HQ offers a performance similar to the Haswell-based Core i7-4960HQ (2.6 - 3.8 GHz). Thus, the CPU has sufficient power for demanding applications, modern games and intense multitasking.
Graphics
The integrated Iris Pro Graphics 6200 (GT3e) offers 48 Execution Units (EUs) clocked at 300 - 1050 MHz, which can access 128 MB of dedicated eDRAM memory. For an integrated graphics solution, the Iris Pro Graphics 6200 achieves remarkable performance levels and competes with low-end or mid-range graphics cards such as the GeForce 940M. Nevertheless, demanding games as of 2015 will be playable only in low or medium 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 i7-5750HQ 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).
Intel Core i7-5557U
► remove from comparison
The Intel Core i7-5557U is a fast dual-core processor based on the Broadwell architecture, which has been launched in January 2015. With a TDP of 28 W, the CPU is suited for medium-sized ultrabooks and notebooks, whereas smaller devices will use more power efficient ULV models such as the Core i7-5600U (15 W TDP). In addition to two CPU cores with Hyper-Threading clocked at 3.1 - 3.4 GHz (2 Cores: 3.4 GHz as well), the chip also integrates an Iris Graphics 6100 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i7 is manufactured in a 14 nm process with FinFET transistors.

Performance
Thanks to its improved architecture, the Core i7-5557U should end up slightly faster than the Haswell-based Core i7-4610M (37 W). Thus, the CPU has sufficient power even for demanding applications and multitasking.
Graphics
The integrated Iris Graphics 6100 offers 48 Execution Units (EUs) clocked at 300 - 1100 MHz. Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock. In addition, the GPU benefits from faster memory speeds up to LPDDR3-1866 (Haswell: DDR3-1600). We expect the Iris Graphics 6100 to be significantly faster than the former Iris Graphics 5100. Nevertheless, demanding games as of 2015 should be playable only in low or medium settings.

Power Consumption
The i7-5557U is rated at a TDP of 28 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for medium-sized ultrabooks 13-inches or greater.
