Haswell microarchitecture (4th generation

"Haswell-DT" (quad-core, 22 nm)

• All models support: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA3, F16C, (BMI1)(Bit Manipulation Instructions1)+BMI2, Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (an NX bit implementation), Intel VT-x, Hyper-threading, Turbo Boost 2.0, AES-NI, Smart Cache, Intel Insider
• All models except the i7-4770K additionally supported Intel TSX-NI at launch, but support was disabled in later stepping and microcode updates, due to the incorrect implementation, that couldn't be solved by microcode without hurting performance or fixing it fully.
• All models except the i7-4770K additionally support Intel VT-d
• All models except the i7-4770K and i7-4790K additionally support vPro and TXT
• Transistors: 1.4 billion
• Die size: 177 mm²
