One of the 22 nanometers Ivy Bridge processors released by Intel this 2012 is the Core i5-3427U for Ultraportable laptop PC. The Intel Core i5-3427U is an Ultra-Low Voltage (ULV) dual-core microchip processor comprising of Central Processing Unit (CPU), PCI Express 3.0 interface, Dual-channel DDR3 memory controller, Direct Media Interface, and HD Graphics 4000 video controller.
This Intel Core i5-3427U ULV dual-core processor has an integrated graphics controller dubbed Intel HD Graphics 4000 that features 16 Execution Units (EUs) clocked at 350 MHz up to 1150 MHz due to Turbo Boost which has a performance as good as AMD Radeon HD 6620G.
The Intel Core i5-3427U dual-core processor features Hyper-Threading technology which has the ability of enhancing the processing power of the processor up to 30%. Further to that, it also features 3MB level 3 cache, 512 KB L2 cache, 128 KB L1 cache and runs at the base clock speed of 1.8 GHz. This Intel Core i5-3427U processor supports also Turbo Boost technology which is the ability of the processor to overclock automatically when the thermal and electrical aspects are met. Due to Turbo Boost this processor can speed up automatically up to 2.6 GHz when both cores are activated; and 2.8 GHz when only one of the cores is activated.
Moreover, this Third Generation Ivy Bridge processor, Intel Core i5-3427U, also features Virtualization VT-x, AES, Thermal Monitoring, Execute Disable Bit Intel 64, Anti-Theft, My WiFi, Idle States, Enhanced SpeedStep and more.
In comparison to other processor in terms of PassMark Rating, this Intel Core i5-3427U dual-core Ivy Bridge processor has a PassMark Rating of about 3692. This is slower compared to Intel Core i5-3320M with a rating of 3918, Intel Core i7 2640M with a rating of 4209, AMD A10-4600M with a rating of 5129, AMD A8-4500M with a rating of 4174, and Intel Core i7-3720QM which has a rating of 9078, but faster compared to Intel Core i5-3317U with a rating of 2974, AMD A8-3500M with a rating of 3166, and AMD A6-3400M which has a rating of 3539.
Additionally, this Intel Core i5-3427U dual-core processor has Thermal Design Power (TDP) of 17 Watts which makes it best suited for Ultraportable notebook PCs.
