Intel Core i3-5020U vs Intel Core i3-5157U

Intel Core i3-5020U

► remove from comparison Intel 5020U

The Intel Core i3-5020U is an ULV (ultra low voltage) dual-core processor based on the Broadwell architecture, which has been launched in early 2015. In addition to two CPU cores with Hyper-Threading clocked at 2.2 GHz (no Turbo), the chip also integrates an HD Graphics 5500 GPU and a dual-channel DDR3(L)-1600 memory controller. The Core i3 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 relatively high clock rate, the Core i3-5020U matches the multi-thread performance of a Core i5-4200U. Due to the missing Turbo Boost, however, the single-thread performance is somewhat lower.

Overall, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications and multitasking.

Graphics

The integrated HD Graphics 5500 offers 24 Execution Units (EUs), however only 23 EUs (clocked at 300 - 900 MHz) are active in this case. 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 beat 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.

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 i3-5020U is rated at a TDP of 15 W (10 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 i3-5157U

► remove from comparison Intel 5157U

The Intel Core i3-5157U 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 i3-5010U (15 W TDP). In addition to two CPU cores with Hyper-Threading clocked at 2.5 GHz (no Turbo), the chip also integrates an Iris Graphics 6100 GPU and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i3 is manufactured in a 14 nm process with FinFET transistors.

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

Performance

Thanks to its improved architecture, the Core i3-5157U performs slightly better than the 100 MHz higher clocked Core i3-4110M (Haswell, 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 - 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 Iris Graphics 6100 is around 20 percent faster than the former Iris Graphics 5100. Demanding games as of 2015 will be playable only in low or medium settings.

Power Consumption

The i3-5157U 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.
