Intel Core i7-3517U - 4000 kB L3 cache, 22nm technology

Another Ivy Bridge processor is now available in the computer market, the Intel Core i7-3517U. It is an ultra-low voltage processor (ULV) released in the 2nd quarter of 2012. This ULV processor, Intel Core i7-3517U, runs at the base clock speed of 1.9 GHz (1900 MHz) but because it has Turbo Boost technology it can overclock automatically up to 2.8 GHz when both cores are active and 3.0 GHz if only one of the cores is active. It also supports Hyper-Threading technology to handle up to four threads in parallel for additional processing power.

The Intel Core i7-3517U is a dual-core processor that offers 4 MB L3-Cache, 512kB level 2 cache and 128kB level 1 cache. Since this Intel Core i7-3517U dual-core processor is part of the family of the Ivy Bridge architecture it is also produced at about 22nm technology and uses 3D transistors for better energy efficiency.

This Intel Core i7-3517U dual-core processor also features integrated PCI Express 3.0, DDR3(L)-1600 support and other features such as Turbo Boost 2.0, Hyper-Threading, Virtualization VT-x, Virtualization for Directed I/O (VT-d), Trusted Execution, AES, Intel 64, Anti-Theft, My WiFi, Idle States, Enhanced SpeedStep, Thermal Monitorin, Execute Disable Bit and more.

It has an integrated graphics controller called Intel HD Graphics 4000 that offers 16 Execution Units (EUs) which is clocked at around 350 MHz up to 1150 MHz because of Turbo Boost, providing a performance comparable with entry-level discreet class GPUs.

This ultra-low voltage Intel Core i7-3517U processor has a thermal design power (TDP) of about 17 watts which makes it suitable for small and ultraportable laptop PCs.

This  Intel Core i7-3517U processor has a PassMark rating of about 4100, this is as powerful as Intel Core i5-2450M which has a rating of 3900, but more powerful compared to Intel Core i5-3317U with a rating of about 2700 and Intel Core i7-2677M with a rating of about 3200 but less powerful compared to Intel Core i7-3610QM which has a rating of 8333.
