INTEL® CORE™ I7

*
TheHãng Intel Vi xử lý Core i7-5500Uis an ULV (ultra low voltage) dual-core processor based on the Broadwell architecture, which has been launched in January 2015. In addition to lớn two CPU cores with Hyper-Threading clocked at 2.4 - 3.0 GHz (2 Cores: 2.9 GHz), the chip also integrates an HD Graphics 5500 GPU and a dual-channel DDR3(L)-1600 memory controller. The bộ vi xử lý Core i7 is manufactured in a 14 nm process with FinFET transistors.

Compared lớn theVi xử lý Core i7-5550U, the i7-5500U features a higher CPU base clock, but integrates a somewhat slower GPU.

Architecture

Broadwellrepresents 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 kích thước fit for more compact packages & devices.

Further advantages result from the revised microarchitecture of Broadwell. Due lớn its improved branch prediction, bigger buffer sizes (1500 instead of 1000 entries in the L2 TLB) and other tweaks, the performance per clochồng 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 lớn its improved architecture, the Core i7-5500U beats the slightly lower clockedChip Core i7-4500U(Haswell, 15 W) by about 5 - 15 percent và matches theVi xử lý Core i5-4258U(Haswell, 28 W).Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications & multitasking.

Graphics

The integratedHD Graphics 5500offers 24 Execution Units (EUs) clocked at 300 - 950 MHz. Similar to the CPU core, the GPU architecture (Hãng sản xuất Intel Gen 8) has beenthoroughly revised for improved performance-per-clochồng. Therefore, the HD Graphics 5500 outperforms theHD Graphics 4400(đôi mươi EUs) as well as theHD Graphics 5000(40 EUs), both part of the Haswell generation.Nevertheless, most games as of 2015 will be playableonly in low settings.

Broadwell is the first Hãng Intel chip to lớn 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 i7-5500U is rated at a TDPhường of 15 W (7.5 W cTDP Down) including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited even for small ultrabooks 11-inches and greater.
