Intel Core i5-5350H vs Intel Core i5-5250U vs Intel Core i5-5300U

Intel Core i5-5350H

The Intel Core i5-5350H is a fast dual-core processor based on the Broadwell architecture, which has been launched in June 2015. In addition to two CPU cores with Hyper-Threading clocked at 3.0 - 3.5 GHz (2 Cores: 3.5 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 i5 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 i5-5350H offers a performance similar to the Haswell-based Core i7-4610M (3.0 - 3.7 GHz) and is one of the fastest dual-core CPUs in mid-2015. Thus, the CPU has sufficient power even for demanding applications and 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 i5-5350H is rated at a TDP of 47 W including the graphics card, memory controller and VRMs. However, power consumption in CPU-only workloads will be significantly lower. Overall, the CPU is best suited for laptops 15-inches or greater.

Intel Core i5-5250U

The Intel Core i5-5250U is an ULV (ultra low voltage) dual-core processor based on the Broadwell architecture, which has been launched in January 2015. In addition to two CPU cores with Hyper-Threading clocked at 1.6 - 2.7 GHz (2 Cores: 2.5 GHz), the chip also integrates an HD Graphics 6000 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i5 is manufactured in a 14 nm process with FinFET transistors.

Compared to the Core i5-5200U, the i5-5250U features a lower CPU base clock, but integrates a somewhat faster GPU.

There are also some new instruction set extensions designed for cryptographic applications.

Performance

Thanks to its improved architecture, the Core i5-5250U ends up 5 - 15 percent faster than the slightly lower clocked Core i5-4250U and matches the Core i5-4350U (both Haswell). Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications and multitasking.

Graphics

The integrated HD Graphics 6000 offers 48 Execution Units (EUs) clocked at 300 - 1000 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). Overall, the HD Graphics 6000 is about 20 - 25 percent faster than the former HD Graphics 5000 (40 EUs), part of the Haswell generation. 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 i5-5250U is rated at a TDP of 15 W (9.5 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.

Intel Core i5-5300U

The Intel Core i5-5300U is an ULV (ultra low voltage) dual-core processor based on the Broadwell architecture, which has been launched in January 2015. In addition to two CPU cores with Hyper-Threading clocked at 2.3 - 2.9 GHz (2 Cores: 2.7 GHz), the chip also integrates an HD Graphics 5500 GPU and a dual-channel DDR3(L)-1600 memory controller. The Core i5 is manufactured in a 14 nm process with FinFET transistors.

Compared to the Core i5-5350U, the i5-5300U features a higher CPU base clock, but integrates a somewhat slower GPU.

Similar to the CPU core, the GPU architecture (Intel Gen 8) has been thoroughly revised for improved performance-per-clock. Therefore, the HD Graphics 5500 is able to outperform the HD Graphics 4400 (20 EUs) as well as the HD Graphics 5000 (40 EUs), both part of the Haswell generation. Nevertheless, most games as of 2015 will be playable only in low settings.
