Intel Launches 'Dunnington' Six-Core Server Processors

Designed for virtualization environments, the latest Xeon-branded products offer frequencies up to 2.66 GHz and power levels starting at 50 watts.

Intel (NSDQ: INTC) on Monday launched its first six-core server processors, aiming the offering at virtualized environments and data-demanding workloads, such as databases, business intelligence, ERP applications, and server consolidation.
The processors are among seven Xeon chips introduced as the 7400 series, which also include four-core processors. The latest products offer frequencies up to 2.66 GHz and power levels starting at 50 watts. The lowest voltage six-core processor is 65 watts.

The series is compatible with Intel's existing 7300 series platforms and the 7300 chipset with memory capacity up to 256 GB. The top-of-the-line X7460 six-core processor has an L3 cache of 16 MB, a 1,066-MHz front-side bus, and a maximum power consumption of 130 watts.
Code-named Dunnington, the six-core processors are the last CPUs of the Penryn generation. Intel plans to start shipping chips built with its next-generation core microarchitecture, code-named Nehalem, this year.
In shipping a six-core processor, Intel is breaking from the tradition of doubling the number of cores in the previous generation. The company's decision not to wait to ship an eight-core product, which would be a doubling of Intel's current quad-core Xeon, reflects the high demand among customers for higher-performing chips, said Shane Rau, analyst for market researcher IDC. Not having the "performance crown" can quickly lead to lost business.
"The market for server processors have been more volatile than one would have expected," Rau told InformationWeek. "Customers will move over in a space of only a quarter or two from one vendor to the next."
Intel appears to be ahead in the performance race, but rival Advanced Micro Devices isn't standing still. It has a six-core Opteron server processor in the works and plans to skip eight cores and go directly to a 12-core processor in 2010.
As of the second quarter of this year, Intel had 86.2% of the market for x86 server processors, and AMD 13.8%, according to IDC. During the same quarter a year ago, Intel had 86.8% and AMD 13.2%.
More than 50 computer manufacturers plan to ship products with Intel's latest processors. Four-socket rack servers are expected from Dell, Fujitsu, Fujitsu-Siemens, Hitachi, IBM, Hewlett-Packard, NEC, Sun Microsystems, Supermicro, and Unisys. Four-socket blade servers will be available from Egenera, HP (NYSE: HPQ), Sun, and NEC; and servers that scale up to 16 sockets are planned by IBM (NYSE: IBM), NEC, and Unisys (NYSE: UIS).
Among software vendors, Citrix (NSDQ: CTXS) and VMware are expected to support Intel's six-core processors with their virtualization technology. Virtualization, primarily used for server consolidation in data centers, is a key focus for Intel's latest products.
During a launch event for the media in San Francisco on Monday, Intel held a panel discussion with executives from Yahoo, Oracle, VeriSign, and MySpace. While server consolidation remained the biggest use for virtualization, the executives said they plan to expand the use of the technology in other areas.
Richard Buckingham, director of system engineering for MySpace, said the social network has 700 virtual machines running off of 32 hosts in its testing and development systems.
MySpace does not use virtualization in its production environments because of the massive scaling requirements of the online social network. "We can't really build anything where there's a single [maximum] scale point," Buckingham said.
In the future, MySpace is looking to incorporate virtualization in the configuration management systems it'll be building for its production servers, which number 12,000, Buckingham said. "We can do some clever things in terms of patching Windows servers and things like that."
In terms of server consolidation, the panelists expected the six-core processors and their greater memory capacity to enable them to consolidate more applications in a single server. "The faster the servers are the fewer we have to buy, and that's a good thing," said Campbell Webb, a VP in IT at Oracle (NSDQ: ORCL).
Pricing for the Xeon 7000 sequence processors ranges from $856 to $2,729 in quantities of 1,000.

Intel G-43

The Intel G43 chipset is like the G45 but only it does not support HDCP. Therefore, there is no HiDef about this chipset. Very rare to be found implemented in an actual motherboard, the G43 is the lowest of the lot.

Therefore, the G43 does everything like DX10 and SM 4.0 but no HDMI. However, it has the Intel Clear Video technology like the G45, which provides the basic enhancements to
non-HiDef video playback.

Intel G-45

As I mentioned earlier that most of the budget gamers prefer these mid-ranged motherboards, what’s more interesting is that out of these gamers, many prefer a motherboard with a good on-board GFX solution. To cater such a need, Intel has launched the G45 and the G43 chipsets.

The Intel G45 is essentially the Intel P45 but has a n on-board graphics solution and not just any plain ordinary graphics solution... this time around, Intel place its latest Intel Graphics Media Accelerator X4500!So, out of the box, you will get:

• Microsoft’s DirectX 10
• OpenGL 2.0 standard
• Shader Model 4.0

Of course, there is a difference in G45 and G43: G45 has HDCP Compliance. Therefore, this makes it the perfect budget Home Theater System, as it will play HD-DVD and BlueRay at the very best. Therefore, for the G45, GMA X4500HD has a rear HDMI video output. Just like Nvidia and AMD have their hardware processing (AVIVO HD with UVD by AMD and PureVideo HD by Nvidia), Intel's GMA X4500HD too supports H.264 playback at 1080p resolution.

Intel P-43

The Intel P43 is almost the exact replica of the Intel P45. However, details regarding this board are vague and so far, the only difference that is known is the presence of just one PCI Express slot running at x16. This is a huge difference though as it means more PCI conventional slots. So this might be the controversial variant in the 4-Series in my view. For those who are never going to go CrossFire, this might be the best option. The Intel P43 is going to be rare and has yet to be implemented by any motherboard manufacturer.

Intel P-45

The Intel P45 is the leader in this lineup. Asus was the first one to roll out its collection of motherboards based on Intel P45 chipset. In addition, at the time of writing, Asus has a complete series called P5Q. I reviewed two boards the Asus P5Q Deluxe and the Asus P5Q3 Deluxe and I was blown away with what the P45 in Asus hands is capable of!

The P45 Express chipset comes with PCI Express 2.0 capability. As before, if used single, you get a 16-lane interface and if you use both slots for GFX, you get 8-lane on each of the two PCI Express slots.The P45 Express supports a maximum front-side bus speed of 1333 MHz. this means CPU with front-side bus speed of 1600 MHz will not fit. Therefore, with the exception of Intel QX9775 and Intel QX9770, all current Intel CPUs including the 45nm-based processors will work fine.

Another well-known feature that has been present for quite some time on recent Intel chipsets is the Matrix Storage technology. Once optical drives with SATA interface are mainstreamed, the last remaining Primary PATA/IDE port will be forgotten as well. The Matrix Storage allows external SATA drives connected through the special eSATA ports to be a part of the internal SATA RAID array(s).One of the interesting things to be seen on the Asus P5Q Deluxe and Asus P5Q3 Deluxe was the EZ Backup feature. This feature translates directly to the Intel’s original feature called Rapid Recover Technology. User can simply copy the entire system drive’s image to backup hard drive and if there is ever a need to restore system, this technology will simply restore the image from the backup hard drive to the system drive.Now, for the memory architecture, DDR2 is native-supported at 800 MHz and DDR3 is clocked at 1066 MHz. One thing to note is that if DDR3 is the memory architecture then the total possible memory installable is reduced to 8 GB instead of the 16 GB in DDR2 mode. Of course, we are using a 64 Bit OS when talking a memory size beyond 3 GB. Using DDR2 under dual-channel interleaved, the maximum transfer rate achievable is 6.4 GB/second + 6.4 GB/second = 12.8 GB/second. Similarly, using DDR3 the maximum transfer rate is 8.5 GB/second + 8.5 GB/second = 17 GB/second. The "Flex Memory Technology" and "Turbo Memory" are two memory related technologies also worth mentioning here. Flex Memory or Flexible Memory allow RAMs modules of different sizes (Gigabytes/Megabytes) to installed in same channel and still allow dual-channel mode. The Turbo Memory is somewhat similar to Windows Vista’s ReadyBoost technology, but rather than having to attach a USB device, Turbo Memory features a NAND flash memory module(s) installed directly on the motherboard.

Intel Core i7

Overview:-

Intel Core i7 is a family of three Intel desktop x86-64 processors, the first processors released using the Intel Nehalem microarchitecture and the successor to the Intel Core 2 family. All three models are quad-core processors. The Core i7 identifier applies to the initial family of processors codenamed Bloomfield. Intel representatives state that the moniker Core i7 does not have any deeper meaning. The name continues the use of the successful Core brand. Core i7, first assembled in Costa Rica, was officially launched on November 17, 2008 and is manufactured in Arizona, New Mexico and Oregon, though the Oregon plant is moving to the next generation 32 nm process.

Features:-

The Nehalem architecture has many new features, some of which are present in the Core i7. The ones that represent significant changes from the Core 2 include:

• The new LGA 1366 socket is incompatible with earlier processors.
• On-die memory controller: the memory is directly connected to the processor.
• Three channel memory: each channel can support one or two DDR3 DIMMs. Motherboards for Core i7 have four (3+1) or six DIMM slots instead of two or four, and DIMMs can be installed in sets of three or two.
• Support for DDR3 only.
• No ECC support.
• The front side bus is replaced by QuickPath interface. Motherboards must use a chipset that supports QuickPath.
• The following caches:
• 64 KB L1 instruction and 64 KB L1 data cache per core
• 256 KB L2 cache (combined instruction and data) per core
• 8 MB L3 (combined instruction and data) "inclusive", shared by all cores
• Single-die device: all four cores, the memory controller, and all cache are on a single die.
• "Turbo Boost" technology allows all active cores to intelligently clock themselves up in steps of 133 MHz over the design clock rate as long as the CPU's predetermined thermal and electrical requirements are still met.
• Re-implemented Hyper-threading. Each of the four cores can process up to two threads
  simultaneously, so the processor appears to the OS as eight CPUs. This feature was present in the older NetBurst architecture but was dropped in Core.
• Only one QuickPath interface: not intended for multi-processor motherboards.
• 45nm process technology.
• 781M transistors for the quad core version.
• 263mm2 Die size.
• Sophisticated power management can place an unused core in a zero-power mode.
• Support for SSE4.2 & SSE4.1 instruction sets.

Processor Cores:-

• The clock rates listed here are as specified by Intel for normal mode. "Turbo boost" can increase the rate on active cores in steps of the base clock (133MHz if not overclocked) up to a predetermined limit for short periods when required, which can be useful with single threaded applications.
• The 965 XE has separate unlocked multipliers for memory and cores.
• Core clock above those in the table are not guaranteed by Intel. Rates above 5GHz have been reported.
• Memory rates above those in the table are not guaranteed by Intel. Rates above DDR3-2000 have been reported.
• The processor has a Thermal Design Power of 130W and will slow itself down if this power is exceeded. This feature can be disabled from an option in most of the new motherboards' BIOS.
• Prices are Intel's wholesale prices for lots of 1,000 units in USD.

Performance:-

• The Inquirer managed to get a 965 engineering sample to a core clock speed of up 4GHz with fan cooling and Turbo Boost alone.
• IT OC Taiwan overclocked an engineering sample of the 965, to 4.20 GHz with a QPI speed of 200 MHz and a multiplier value of 21.0x. A vCore setting of 1.72V was used, which is far higher than the stock of 1.25V.
• A Core i7 940 system running at stock speeds has obtained a 3DMark Vantage benchmark CPU score of 17,966. A Core i7 920 system scored 16,294 running at stock speeds. An Intel Core 2 Extreme QX9770, a very expensive member of the previous generation of Intel processors (costing over four times the price of the 920 at its launch), scored 13,182 also running at stock speeds.
• AnandTech tested the Intel QuickPath Interconnect (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.
• Core i7-975 will have the new D0 Stepping.
