Nvidia is extending its support for Intel's upcoming Core i7 processors while it prepares to announce next-generation integrated graphics silicon.
The announcement marks an effort to expand Nvidia offerings on Intel's next high-end desktop platform, which had previously been referred to as "Bloomfield." Intel branded it Core i7 prior to the company's developer forum last week. Nvidia has already said that it has no intention to build a chipset for Intel's next-generation interconnect technology called QuickPath Interconnect or QPI, which is part of the i7 design.
Nvidia said Thursday that it will license its Scalable Link Interface (SLI) technology for Intel's Core i7 processor. Nvidia's technology will work in tandem with Intel's X58 chipset, the supporting silicon for the Core i7, which is due to ship in volume in the fourth quarter.
SLI allows systems to be configured with multiple graphics boards. So, for example, system builders and users can build systems with two, three, or four Nvidia boards.
In essence, Nvidia is offering what it calls "native" licensing of SLI to its partners and system builders. Native licensing will not require the use of Nvidia's nForce 200 bridge chip and thereby the company hopes to broaden the range of its graphics offerings on i7-based PCs.
To date, Nvidia has only offered nForce 200, "which is basically an SLI chip that acts like a PCI Express bridge. That's been the only solution and that's been a very high-end solution. We'll continue to offer this," said Tom Peterson, director of Technical Marketing for MCP production at Nvidia.
PCI, or peripheral component interface, is the most common interface inside a PC for add-in boards.

Intel's latest processor eyes larger sized notebook PCs
Intel Corp. introduced the Mobile Intel Pentium 4 processor 548 supporting Hyper-Threading (HT) Technology for the portability market segment.
Designed for larger-sized notebook PCs, also known as "desktop replacements," that typically feature large screens, full-size keyboards and multiple drives, this new processor allows users to take advantage of multithreaded and processor-intensive multimedia applications in a portable form factor.
The Mobile Intel Pentium 4 processor 548 supporting HT Technology is built on the company's 90nm process technology and offers other features such as a 1MB Level 2 cache, 13 new Streaming SIMD 3 Extensions (SSE3), enhancements to the Intel NetBurst microarchitecture, and a processor speed of 3.33GHz. Additionally, this processor offers such power management features as support for Enhanced Intel Speedstep technology, deep sleep and deeper sleep that enables lower thermals than its desktop counterpart. This device works with Intel's 852GME and 852PM chipsets.

The Latest Processors: AMD Athlon 64 FX-57, Intel Pentium D 820, Pentium 4 670
It took relatively long to prepare this material, as new processors kept being added to it in the process. We initially planned it as a review of the Pentium 4 670, but then we got hold of the Pentium D 820, and recently of a new single core flagship from AMD: Athlon 64 FX-57. However, despite the significant differences in positioning and performance, we still tried to bring tests of all the above mentioned processors together into a single article. Hopefully, it will have no effect on its content quality regarding each CPU. At first we are going to say a few words about each of the latest models.
Pentium 4 670
It's a logical successor to the Pentium 4 6xx series, one of its closest representatives is the previously reviewed Pentium 4 660. Thus, there is nothing special about it: the same core architecture (Prescott-2M) as in the Pentium 4 660, the same bus clock (800MHz in terms of bandwidth) and the L2 Cache size (2MB), but its clock has grown by another 200 MHz (i.e. up to 3.8 GHz). Judging from the latest (available in Internet) Intel's plans, the Pentium 4 670 must be the last processor in this line, as the 4GHz CPU based on Prescott-2M disappeared from the roadmap of this company last year. However, as Stephen King put it, "sometimes they come back"...
Pentium D 820
It's the lowest CPU in the series of multi-core desktop "non-extreme" processors from Intel. The key difference between the Pentium D and the Pentium XE, as we have already written, is that unlike the latter, Pentium D has two physical cores, but it doesn't support Hyper-Threading. Besides, the Pentium D 820 operates at the lowest clock among the entire series of Prescott-like CPUs: 2.8 GHz. There is nothing new in other respects: it's just a Pentium XE, but without Hyper-Threading. The main peculiarity of the Pentium D series is more than democratic prices (especially considering dual cores): according to the official data from the manufacturer, wholesale prices for Pentium D 820/830/840 currently amount to $241/316/530. For comparison: the wholesale price for the Pentium 4 670 is $851, Athlon 64 FX-57 — $1031. So, Pentium D 820 can quite set up for the title of a "people's dual core processor" (for quite well-off people, though).
Athlon 64 FX-57
The renowned successor to Athlon 64 FX-55 acquired a new 90nm San Diego core (its differences from Venice are minimal) with an improved memory controller and SSE3 support. Besides, the clock has grown by another 200 MHz to reach 2.8 GHz. It's the first Athlon 64 FX manufactured by the 90nm process technology supporting SSE3. It's an indirect sign that this process technology is streamlined to manufacture flagship processors offering the highest performance. From the users' point of view, the new Athlon 64 FX is no different from the previous model: it is installed into the same CPU socket as the previous Athlon 64 FX-55 and makes no additional requirements to a motherboard.

AMD Changed Naming Scheme For 45nm
According to industry sources, AMD has decided to modify the naming scheme for their 45nm desktop processors. While AMD is keeping the Phenom X3 phenom x3 and Phenom X4 branding, the model numbers have changed from four digits to five digits in length.
According to sources, AMD intends to start shipping DDR2 variants of Deneb this year as you can see from the table below.
Rumored 45nm Phenom Processor RoadmapName Freq. HT 3.0 Freq. Memory Total Cache TDP Release Date
Phenom X4 20x00 3.0GHz 4.0GHz* DDR3-1333 8MB 125W Q2 2009
Phenom X4 20550 3.0GHz 4.0GHz* DDR2 8MB 125W Q4 2008
Phenom X4 20x00 2.8GHz 4.0GHz* DDR3-1333 8MB TBD Q1 2009

Phenom X3 12x00 2.6GHz 4.0GHz* DDR3-1333 1.5MB 95W Q2 2009
*There are obviously errors in this rumored roadmap as HyperTransport 3.0 has a maximum clockspeed of 2.6GHz, and even the newly released HyperTransport 3.1 only runs at a maximum of 3.2GHz. It is possible that 4.0GT/s is meant instead, equating to a 2.0GHz HT 3.0 clockspeed across the board.

ntel core i7 cPU tested
Chinese-language PC Online is one step ahead of the game. The website already had the chance to test and benchmark the performance of one of Intel's upcoming quad-core Core i7 CPUs, namely the Extreme 940 model.
Now, remember, these new chips aren't expected to come out until sometime in November, so the fact that they have already been tested is quite an important aspect. This is all the more true especially since, in order to fully set up a benchmarking platform for these CPUs, you require not only the processor itself, but also an X58-based motherboard, which comes with the only chipset that can support Intel's upcoming socket LGA1366.
The test was ran in comparison with Intel's Core 2 QX9770 (featuring 12MB of L2 cache) at both reference and overclocked core speeds.The core 2 test platform included an ASUS X48 motherboard, two 1GB Apacer DDR3-1333 memory modules, a 500GB SATA 7200RPM Seagate hard drives and a GeForce GTX 260 graphics card. The Core i7 test platform featured the same components, plus the Intel X58 motherboard and the Core i7 Extreme 940 CPU, running at a reference clock speed of 2.93GHz and featuring 8MB of L3 cache.In regard to the software, the testing systems ran on a Windows Vista operating system, using the latest drivers. Benchmarking software included Super PI 1.4, Everest Ultimate 4.6, WinRAR 3.71, CINEBENCH R10, Fritz Chess Benchmark, 3DMark2006 and 3DMark Vantage version 101. Also, both CPUs were tested using some of the latest DirectX 9 and DirectX 10 games.
As it turns out, the Extreme Core i7 CPU outperformed both the overclocked and the standard Core 2 QX9770 processor in most benchmarks. Practically, the only tests where the Core i7 CPU could not live up to its name were the Super PI 1.4 benchmark and some of the gaming applications, including DirectX9 Call of Duty 4, Half Life 2: Ep2, and DirectX10 Company of Heroes. Aside from that, in 3DMark Vantage, the Core i7 940, clocked at 2.93GHz, achieved a CPU score of 18252, while the overclocked Core 2 could only go as high as 13128 points.
It is clear that the new Core i7 CPU will deliver an impressive performance boost compared with Intel's current CPU offering. However, it would have been nice to know how the non-Extreme Core i7 920 model would perform against some of Intel's more decently priced Core 2 models - especially since the Core i7 920 will probably become the most successful on the market, thanks to its comparatively lower estimated price tag.

Intel® GPU/CPU combo
Bloomfield will apparently feature a 1366 pin socket (ouch) and feature "QuickPath" - Intel's answer to AMD's "HyperTransport" along with up to three channels of DDR3 memory. The new core apparently will have 8MB of L2 and use QuickPath to connect to a "Tylersburg" northbridge that will provide PCIe 2.0 lanes.Strangely enough, less than six months later there will apparently be a "Lynnfield" going to a 1160 pin socket with four cores and hyperthreading, 8MB of L2, dual DDR3 channels, using PCIe as a chip to chip bus. Frankly, this sounds weird to me. Why on earth would Intel go to a 1366 pin chip, to go to a 1160 pin chip less than six months later? The only way that this would make sense is if one of the chips was destined for the low end integrated market.Let's peek into our crystal ball... to reduce costs, you have to simplify designs. What if Lynnfield integerated the GPU? With PCIe integrated onto the chip, it is not farfetched to consider that Intel may also consider integrating a couple of SATA channels and some USB2.0 channels... then you could have a nice little quad core "SOC" (System on a Chip) allowing very low part count integrated low end designs. Such an SOC really would only be suitable for low end machines as the GPU would have to share memory bandwidth with the four core / eight thread CPU portion, so even a hypothetical dual channel 2000MHz DDR3 system with close to 32GB/sec bandwidth would be hard put to exceed the performance of an 8600GT - and it would starve the processor for memory bandwidth at that. To make matters even more confusing, the referenced roadmap also shows a mainstream "Clarksfield" part using a 989 pin rPGA socket. UGH. Thatz it!
The main circuit board of a microcomputer.
The main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive; sometimes you will find that the motherboard has other integrated devices such as an audio card and video card. The motherboard is the largest circuit board in most computers and is held on by several screws.
Intel® Processors
The CPU is the brain of any PC. The CPU works by taking deta out of memory , processing it and placing it back into memory it is through memory that the other devices that make up the PC interact with the CPU it may be helpful if you think of the CPU as an agents pending its time going from the one device to another , multitasking its help is needed.if the processing job the CPU is asking to do is lengthy , it may not be available to the other devices connected to the PC until that job is completed . this process explains why sometime you can type a command and it seems to take a while for the computer to respond. the CPU was processing another instruction , and took a moment for it to get to the keyboard's memory location , retrieve your key stroke, determine what keystroke meant , and execute that instruction
The processor's performance is measured in terms of the amount of data it can process at one time and the speed at which it can process that data . than data is measured in bits processing speed in megahertz ( MHz ).

The Core 2 brand, , ,
The Core 2 brand refers to a range of Intel's consumer 64-bit single- and dual-core and 2x2 MCM (Multi-Chip Module) quad-core CPUs with the x86-64 instruction set, based on the Intel Core microarchitecture, derived from the 32-bit dual-core Yonah laptop processor. (Note: The Yonah's silicon chip or die comprised two interconnected cores, each similar to those branded Pentium M). The 2x2 MCM dual-die quad-core[1] CPU had two separate dual-core dies (CPUs)—next to each other—in one quad-core MCM package. The Core 2 relegated the Pentium brand to a mid-end market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, D, and M brands.
The Core microarchitecture returned to lower clock rate and improved processors' usage of both available clock cycles and power compared with preceding NetBurst of the Pentium 4/D-branded CPUs.[2] 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. Intel's CPUs have varied very wildly in power consumption according to clock rate, architecture and semiconductor process, shown in the CPU power dissipation tables.
The Core 2 brand was introduced on July 27, 2006,[3] comprising the Solo (single-core), Duo (dual-core), Quad (quad-core), and Extreme (dual- or quad-core CPUs for enthusiasts) branches, during 2007.[4] Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches.[5]
