Nehalem (microarchitecture)
From Wikipedia, the free encyclopedia
Nehalem (pronounced /nəˈheɪləm/[1]) is the codename for an Intel processor microarchitecture, successor to the Core microarchitecture.[2] The first processor released with the Nehalem architecture was the desktop Core i7,[3] which was released in November 2008. It was followed by several Xeon processors and by the i3 and i5.[4] Mobile Nehalem-based processors were introduced in September 2009. The first computer to use Nehalem-based Xeon processors was the Apple Mac Pro workstation announced on March 3, 2009.[5] Nehalem-based Xeon EX processors for larger servers were originally expected in Q4 2009,[6] However, they were released in April 2010.[7]
Initial Nehalem processors use the same 45 nm manufacturing methods as Penryn. A working system with two Nehalem processors was shown at Intel Developer Forum Fall 2007.
The microarchitecture is named after the coastal Oregon town of Nehalem.[8][9] Originally it was supposed to be the latest evolution of the NetBurst microarchitecture. Since the abandonment of NetBurst, the codename has been recycled and refers to a completely different project, although Nehalem still has some things in common with NetBurst. Nehalem-based microprocessors utilize higher clock speeds and are more energy-efficient than Penryn microprocessors. Hyper-Threading is reintroduced along with an L3 Cache missing from most Core-based microprocessors.

[edit] Technology
- Two, four, and eight cores
- 45 nm manufacturing process at initial release (with 32 nm variants following)
- Integrated memory controller supporting two or three memory channels of DDR3 SDRAM or four FB-DIMM2 channels
- Integrated graphics processor (IGP) located off-die, but in the same CPU package for Westmere.[10]
- A new point-to-point processor interconnect, the Intel QuickPath Interconnect, in high-end models, replacing the legacy front side bus
- Integration of PCI Express and Direct Media Interface into the processor in mid-range models, replacing the northbridge
- Hyper-threading has been reintroduced.
- Native (monolithic, i.e. all processor cores on a single die) quad- and octo-core processors[11]
- 64 KB L1 cache/core (32 KB L1 Data + 32 KB L1 Instruction) and 256 KB L2 cache/core.
- 4–12 MB L3 cache shared by all cores
- 33% more in-flight micro-operations than Conroe[12]
- Second-level branch predictor and second-level translation lookaside buffer[12]
[edit] Performance and power improvements
It has been reported that Nehalem has a focus on performance, which accounts for the increased core size.[13] Compared to Penryn, Nehalem has:
- 1.1× to 1.25× the single-threaded performance or 1.2× to 2× the multithreaded performance at the same power level
- 30% lower power usage for the same performance
- According to a preview from AnandTech "expect a 20–30% overall advantage over Penryn with a 10% increase in power usage."[14]
- Per Core, clock-for-clock, Nehalem provides a 15–20% increase in performance compared to Penryn.
PC Watch found that a Nehalem "Gainestown" processor has 1.6× the integer performance and 2.4× the floating-point performance of a 3.0 GHz Xeon X5365 "Clovertown" quad-core processor.[13]A 2.93 GHz Nehalem "Bloomfield" system has been used to run a 3DMark Vantage benchmark and gave a CPU score of 17,966.[15] The 2.66 GHz variant scores 16,294. A 2.4 GHz Core 2 Duo E6600 scores 4,300.[16]AnandTech tested the Intel QuickPath Interconnect ("QPI", 4.8 GT/s version) and found the copy bandwidth using triple-channel 1066 MHz DDR3 was 12.0 GB/s. A 3.0 GHz Core 2 Quad system using dual-channel 1066 MHz DDR3 achieved 6.9 GB/s.[17]
Overclocking is possible with Bloomfield processors and the X58 chipset. The Lynnfield processor uses a PCH removing the need for a northbridge chipset.[18]
The Nehalem processors are the first to incorporate the SSE 4.2 SIMD instructions, adding 7 new instructions to the SSE 4.1 set available in the Core 2 series.The Nehalem architecture also significantly reduces atomic operation latency; cutting it to 50% in an attempt to eliminate atomic overhead .[19]
[edit] Westmere
Westmere (formerly Nehalem-C) is the name given to the 32 nm die shrink of Nehalem. The first Westmere-based processors were launched on January 7, 2010 and branded as members of the Core i3, Core i5, and dual-core mobile Core i7 families.
Westmere's features and improvements from Nehalem have been reported as follows:
- Native six-core processors.[20]
- A new set of instructions that gives over 3x the encryption and decryption rate of Advanced Encryption Standard (AES) processes compared to before.[21]
- Delivers seven new instructions (AES instruction set or AES-NI) that will be used by the AES algorithm. Also an instruction called PCLMULQDQ (see CLMUL instruction set) that will perform carry-less multiplication for use in cryptography.[22] These instructions will allow the processor to perform hardware-accelerated encryption, not only resulting in faster execution but also protecting against software targeted attacks.
- AES-NI may be included in the integrated graphics of Westmere.
- Integrated graphics, built into the processor.
- Improved virtualization latency.[23]
- New virtualization capability: "VMX Unrestricted mode support," which allows 16-bit guests to run (real mode and big real mode).
- Support for "Huge Pages" of 1GB in size.
[edit] Code names
Each combination of a Nehalem/Westmere processor die and package has both a separate codename and a product code. Typically, the same dies are used for uniprocessor (UP) and dual-processor (DP) servers, but using an extra QuickPath link for the inter-processor communication in the DP server variant. Like the Core microarchitecture, Nehalem also uses four different processor packages, one for each market segment. The high-end chips with eight cores are only available in the MP server segment, while all others are used in at least two different packages. No details have been released about the Westmere EX processor so far.
