Enhanced Halt State (C1E)
"Whenever the OS executes the halt instruction, the CPU enters what is known as the halt state. Architecturally, what's going on in a halt state is the clock signal is shut off to the CPU for some period of time. With no clock signal, none of the logic in the chip will do anything and thus power consumption is reduced. Performance is also significantly reduced; however, the halt instruction isn't usually called during application usage, so the performance aspects of the halt state aren't very important.
The problem with the halt state is that it does nothing to reduce voltage, only current draw by stopping clocks from going to the CPU. Since Power varies linearly with both current and voltage (P = I * V), you're effectively only addressing half of the problem. The Enhanced Halt State, as Intel calls it, does two things: it reduces the clock speed of the CPU by decreasing the clock multiplier down to its minimum value (on the EE 965 series, that's 14x, or 2.8GHz), then reducing the voltage. The clock speed is reduced and then the voltage is dropped, to maintain stability.
Intel insists that the enhanced halt state is a significantly lower power state than the conventional halt state, thanks to the reduction in voltage in addition to the reduction in clock speed. While the standard halt state causes a linear reduction in power, Intel's enhanced halt state causes an exponential decrease in power, potentially offering better power savings than the standard halt state. The real world impact obviously depends on how idle your system happens to be."
Intel® Streaming SIMD Extensions 4 (SSE4) Instruction Set Innovation ( New For the QX9770Quad Core Extreme )
Unlocking performance and energy efficiency with new instruction set innovations. Integrated into Intel® processors based on Intel® 45nm high-k metal gate silicon technology, Intel® Streaming SIMD Extensions 4 (Intel® SSE4) instructions are Intel's most significant media instruction set architecture (ISA) advancements since 2001.
These new instructions build upon the Intel® 64 architecture ISA and enable Intel processors to deliver superior performance and energy efficiency to a broad range of 32- and 64-bit applications including:
Video encoding and processing
Intel SSE4 is the result of continued work with the ISV community to deliver instruction set extensions that allow developers to easily enhance their products while maintaining the necessary application-level compatibility across processor generations.
Enhanced Intel Speedstep® Technology
Enhanced Intel SpeedStep technology allows the system to dynamically adjust processor voltage and core frequency, which can result in decreased average power consumption and decreased average heat production. By decreasing power and heat on Desktop PCs, system builders can (depending on system configurations) potentially lower acoustics, and even develop more innovative small form factor designs. Additionally, this feature can help address power concerns in companies with sites approaching the limits of bounded electrical infrastructures. Combined with existing power saving features, Enhanced Intel SpeedStep technology can provide an excellent balance between providing power when you need it and conserving it when you don't.
Execute Disable Bit
Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks and prevent harmful software from executing and propagating on the server or network.
Certain boxed Intel desktop processors have support for Intel® Extended Memory 64 Technology1 (Intel® 64), delivering flexibility for operating systems and future software that supports 64-bit computing.
In order to take advantage of this technology, an entire 64bit hardware & software solution stack is required, ranging from processors and device drivers to operating systems, tools and applications.
The primary value to users lies in potential performance improvements achieved by the ability to address >4GB of both virtual and physical memory, the latter also requiring platform/motherboard designs including this much system memory.
Digital media applications are expected to see benefits from Intel 64 1 in their ability to process high quality audio and video, as well as 3D rendering.
Intel® Thermal Monitor 2
The Intel Core 2 Duo processor in the 775-land package also supports a power management capability known as Thermal Monitor 2. This mechanism provides an efficient mechanism for limiting the processor temperature by reducing power consumption within the processor. Thermal Monitor 2 is enabled, and a high temperature situation is detected, the enhanced Thermal Control Circuit causes the processor to adjust its operating frequency and input voltage. This combination of reduced frequency and voltage results in a decrease in processor power consumption. Once the processor has sufficiently cooled and a minimum activation time has expired, the operating frequency and voltage transition back to the normal system operating point.
Intel® Virtualization Technology
Intel ® Virtualization Technology ? delivers improved computing benefits for home users, business users, and IT managers alike. This paper describes the unique requirements that embedded systems and communications infrastructure equipment place on virtualized environments and shows how Intel is working with a number of third parties to extend the benefits of Intel Virtualization Technology to these market segments. Bounded real-time performance can be maintained while using virtualization to consolidate systems; system uptime can be increased by enabling software failover without redundant hardware; and software migration can be performed without bringing down the application. Virtualization also allows legacy applications to co-exist with new applications by executing both software environments in parallel, and it provides the means for applications to take advantage of multi-core processors without re-architecting for multi-threaded execution.
Penryn 45nm Process Improvements
Innovation That Breaks the Performance Barrier
45nm next-generation Intel® Core™ microarchitecture is on its way. With twice the density of Intel® 65nm technology, Intel's 45nm packs about double the number of transistors into the same silicon space. That's more than 400 million transistors for dual-core processors and more than 800 million for quad-core. Intel's 45nm technology enables great performance leaps, up to 50-percent larger L2 cache, and new levels of breakthrough energy efficiency.
Smaller transistors pack the performance punch
Intel's had the world's first 45nm CPUs in-house since early January 2007—the first of fifteen 45nm processor products in development. With one of the biggest advancements in fundamental transistor design in 40 years, Intel's 45nm technology can deliver more than a 20 percent improvement in transistor switching speed, and reduce transistor gate leakage by over 10 fold.
Taking great leaps forward in transistor design
Using a combination of new materials including Hi-k gate dielectrics and metal gates, Intel 45nm technology represents a major milestone as the industry as a whole races to reduce electrical current leakage in transistors—a growing problem for chip manufacturers as transistors get even smaller. And many in the industry have been working to find the right combination of materials and integrate them into a new process technology. But Intel is the first to successfully implement such a combination.
This new transistor breakthrough allows Intel to continue delivering record-breaking PC, laptop, and server processor speeds well into the future. It also ensures that Moore's Law—a high-tech industry axiom that transistor counts double about every two years to deliver more performance and functionality at decreasing cost—thrives well into the next decade.
