While the Core microarchitecture is a major architectural revision it is based in part on the Pentium M processor family designed by Intel Israel.
Introduced GPU on same package and AES-NI Both an 元 cache and hyper-threading were reintroduced again to consumer line in the Nehalem microarchitecture.Ĥ cores on mainstream desktop, DDR3 introduced The consumer version also lacks an 元 cache as in the Gallatin core of the Pentium 4 Extreme Edition, though it is exclusively present in high-end versions of Core-based Xeons. The L1 cache size was enlarged in the Core microarchitecture, from 32 KB on Pentium II / III (16 KB L1 Data + 16 KB L1 Instruction) to 64 KB L1 cache/core (32 KB L1 Data + 32 KB L1 Instruction) on Pentium M and Core/Core 2. This is because the Core microarchitecture is based on the P6 microarchitecture used by Pentium Pro, II, III, and M.
However, Core-based processors do not have the hyper-threading technology as in Pentium 4 processors. Like the last NetBurst CPUs, Core based processors feature multiple cores and hardware virtualization support (marketed as Intel VT-x), and Intel 64 and SSSE3. Intel's CPUs have varied widely in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables. The Core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs while increasing their processing capacity. The Core microarchitecture returned to lower clock rates and improved the use of both available clock cycles and power when compared with the preceding NetBurst microarchitecture of the Pentium 4 and D-branded CPUs. The initial mainstream Core-based processors were branded Pentium Dual-Core or Pentium and low end branded Celeron server and workstation Core-based processors were branded Xeon, while Intel's first 64-bit desktop and mobile Core-based processors were branded Core 2. While architecturally identical, the three processor lines differ in the socket used, bus speed, and power consumption. The first processors that used this architecture were code-named ' Merom', ' Conroe', and ' Woodcrest' Merom is for mobile computing, Conroe is for desktop systems, and Woodcrest is for servers and workstations. However after many generations of successor microarchitectures which used Core as their basis (such as Nehalem, Sandy Bridge and more), Intel managed to eventually surpass the clock rates of Netburst with the Devil's Canyon (Improved version of Haswell) microarchitecture reaching a base frequency of 4 GHz and a maximum tested frequency of 4.4 GHz using 22 nm lithography. The Core microarchitecture initially did not reach the clock rates of the NetBurst microarchitecture, even after moving to 45 nm lithography. High power consumption and heat intensity, the resulting inability to effectively increase clock rate, and other shortcomings such as an inefficient pipeline were the primary reasons why Intel abandoned the NetBurst microarchitecture and switched to a different architectural design, delivering high efficiency through a small pipeline rather than high clock rates. It is based on the Yonah processor design and can be considered an iteration of the P6 microarchitecture introduced in 1995 with Pentium Pro. The Intel Core microarchitecture (formerly named Next-Generation Micro-Architecture) is a multi-core processor microarchitecture unveiled by Intel in Q1 2006.
