CORE I7
Nehalem
Intel Core i7 adalah merek Intel nama untuk beberapa keluarga dari desktop dan laptop 64-bit x86-64 prosesor dengan menggunakan Nehalem, Westmere, dan microarchitectures Sandy Bridge. Merek Core i7 ditargetkan pada bisnis dan high-end pasar konsumen untuk kedua komputer desktop dan laptop, dan dibedakan dari Core i3 (entry level konsumen), Core i5 (konsumen utama), dan Xeon (server dan workstation) merek.
Nama Core i7 diperkenalkan dengan prosesor Quad-core Bloomfield pada akhir 2008. Pada tahun 2009 model Core i7 baru berdasarkan Lynnfield prosesor desktop quad-core dan quad-core Clarksfield ponsel ditambahkan, [38] dan model didasarkan pada prosesor dual-core Arrandale ponsel ditambahkan pada Januari 2010. Prosesor enam-core pertama di jajaran Core adalah Gulftown, yang diluncurkan pada tanggal 16 Maret 2010. Baik Core i7 reguler dan Extreme Edition diiklankan sebagai bintang lima di Processor Intel Penilaian. Pada bulan Januari 2011, Intel merilis generasi kedua dari prosesor Core i7. Baik generasi pertama dan kedua prosesor Intel Core i7 dinilai sebagai 5 bintang di rating prosesor Intel. Generasi kedua dari prosesor Intel inti didasarkan pada inti "Sandy Bridge" dan ditetapkan untuk diperbarui dalam sejak 1 Januari 2012 dengan "Ivy Bridge". 1Footnote: Ini belum diluncurkan, pada 2012/04/22
Dalam setiap dari tiga generasi pertama mikroarsitektur dari merek, Core i7 memiliki anggota keluarga menggunakan dua berbeda tingkat sistem arsitektur, dan karena itu dua soket yang berbeda (misalnya, LGA 1156 dan LGA 1366 dengan Nehalem).Dalam setiap generasi, prosesor Core i7 dengan performa tertinggi menggunakan soket yang sama dan QPI berbasis arsitektur sebagai low-end prosesor Xeon yang generasi, sementara prosesor Core i7-sekolah yang menggunakan soket yang sama dan PCIe / DMI / FDI arsitektur sebagai Core i5.
"Core i7" adalah penerus ke merek Intel Core 2. Intel perwakilan menyatakan bahwa moniker Core i7 dimaksudkan untuk membantu konsumen memutuskan untuk membeli prosesor sebagai lebih baru berbasis Nehalem Produk ini dirilis di masa depan.

Sandy Bridge
Merek Core i7 tetap high-end untuk desktop Intel dan prosesor mobile, yang menampilkan model Sandy Bridge dengan jumlah terbesar L3 cache dan frekuensi clocktertinggi. Sebagian besar model ini sangat mirip dengan saudara kandung yang lebih kecil mereka Core i5. Quad-core Core mobile i7-2xxxQM/XM ikuti sebelumnya "Clarksfield" Core prosesor i7-xxxQM/XM, tapi sekarang juga termasuk grafis terintegrasi.
