Top 5 Features

1. Introduction

The Intel Penryn mircoarchitecture, which included the Core 2 family of processors, was the first mainstream Intel microarchitecture based on the 45nm fabrication process. This allowed Intel to create higher-performance processors that consumed similar or less power than previous-generation processors.

The Intel Nehemiah micro architecture that encompasses the Core i7 class of processors uses a 45nm fabrication process for different processors in the Core i7 family. Besides using the power consumption benefits of 45nm, Intel made some dramatic changes in the Nehemiah micro architecture to offer new features and capabilities in the Core i7 family of processors. This white paper explores the details on some key features and their impact on test, measurement, and control applications.

In the older Penury architecture, the front-side bus (FSB) was the interface for exchanging data between the CPU and the north bridge. If the CPU had to read or write data into system memory or over the PCI Express bus, then the data had to traverse over the external FSB. In the new Nehalem micro architecture, Intel moved the memory controller and PCI Express controller from the north bridge onto the CPU die, reducing the number of external data bus that the data had to traverse. These changes help increase data-throughput and reduce the latency for memory and PCI Express data transactions. These improvements make the Core i7 family of processors ideal for test and measurement applications such as high-speed design validation and high-speed data record and playback.As shown in Figure 1, the previous Intel micro architectures for a single processor system included three discrete components: a CPU; a Graphics and Memory Controller Hub (GMCH), also known as the north bridge; and an I/O Controller Hub (ICH), also known as the south bridge. The GMCH and ICH combined are referred to as the chip set.

3. 2 – Higher-Performance Multiprocessor Systems with QPI

Not only was the memory controller moved to the CPU for Nehemiah processors, Intel also introduced a distributed shared memory architecture using Intel Quick Path Interconnect (QPI). QPI is the new point-to-point interconnect for connecting a CPU to either a chip set or another CPU. It provides up to 25.6 GB/s of total bidirectional data throughput per link.

Intel’s decision to move the memory controller in the CPU and introduce the new QPI data bus has had an impact for single-processor systems. However, this impact is much more significant for multiprocessor systems. Figure 2 illustrates the typical block diagrams of multiprocessor systems based on the previous generation and the Nehalem microarchitecture. The Nehemiah microarchitecture integrated the memory controller on the same die as the Core i7 processor and introduced the high-speed QPI databus. As shown in Figure 2, in a Nehemiah-based multiprocessor system each CPU has access to local memory but they also can access memory that is local to other CPUs via QPI transactions. For example, one Core i7 processor can access the memory region local to another processor through QPI either with one direct hop or through multiple hops.

4. 3 – CPU Performance Boost via Intel Turbo Boost Technology

About five years ago, Intel and AMD introduced multicore CPUs. Since then a lot of applications and development environments have been upgraded to take advantage of multiple processing elements in a system. However, because of the software investment required to re-architect applications, there are still a significant number of applications that are single threaded. Before the advent of multicore CPUs, these applications saw performance gains by executing on new CPUs that simply offered higher clock frequencies. With multicore CPUs, this trend was broken as newer CPUs offered more discrete processing cores rather than higher clock frequencies.

To provide a performance boost for lightly threaded applications and to also optimize the processor power consumption, Intel introduced a new feature called Intel Turbo Boost. Intel Turbo Boost is an innovative feature that automatically allows active processor cores to run faster than the base operating frequency when certain conditions are met.

Intel Turbo Boost is activated when the OS requests the highest processor performance state. The maximum frequency of the specific processing core on the Core i7 processor is dependent on the number of active cores, and the amount of time the processor spends in the Turbo Boost state depends on the workload and operating environment.

5. 4 – Improved Cache Latency with Smart L3 Cache

Cache is a block of high-speed memory for temporary data storage located on the same silicon die as the CPU. If a single processing core, in a multicore CPU, requires specific data while executing an instruction set, it first searches for the data in its local caches (L1 and L2). If the data is not available, also known as a cache-miss, it then accesses the larger L3 cache. In an exclusive L3 cache, if that attempt is unsuccessful, then the core performs cache snooping – searches the local caches of other cores – to check whether they have data that it needs. If this attempt also results in a cache-miss, it then accesses the slower system RAM for that information. The latency of reading and writing from the cache is much lower than that from the system RAM, therefore a smarter and larger cache greatly helps in improving processor performance.

The Core i7 family of processors features an inclusive shared L3 cache that can be up to 12 MB in size. Figure 4 shows the different types of caches and their layout for the Core i7-820QM quad-core processor used in the NI PXIe-8133 embedded controller. The NI PXIe-8133 embedded controller features four cores, where each core has 32 kilobytes for instructions and 32 kilobytes for data of L1 cache, 256 kilobytes per core of L2 cache, along with 8 megabytes of shared L3 cache. The L3 cache is shared across all cores and its inclusive nature helps increase performance and reduces latency by reducing cache snooping traffic to the processor cores. An inclusive shared L3 cache guarantees that if there is a cache-miss, then the data is outside the processor and not available in the local caches of other cores, which eliminates unnecessary cache snooping.
