Intel's New Core i7 and Core i5 Processors Explained
By David Murphy, PCWorld Sep 7, 2009 9:01 PM
Intel's two new Core i7 CPUs (860 and 870) are mid-range counterparts to its top-of-the-line Core i7 900-series chips, and initial tests (using Intel's new DP55KG motherboard) indicate their performance follows suit. Our early tests also show the new entry-level Core i5 750 is the one to watch when it comes to best bang for your buck.
Editor's Note:This story covers the Intel Core i5 and i7 processors that were introduced in September, 2009. To learn about the more recent "Sandy Bridge" versions of these processors, see Intel's Sandy Bridge CPUs: What to Expect . And check out our exclusive lab testing to see how Sandy Bridge stacks up against previous processors.
Intel's full processor breakdown--including the axing of its Core i7 940 processor--includes some potentially confusing differences between the chips. So here's what you need to know.
The existing Core i7 900-series processor lineup, codenamed Bloomfield, now features three separate products: 3.33-GHz Core i7 975, 3.06-GHz Core i7 950, and 2.66-GHz Core i7-920 processors. Between the Core i7-950 and Core i7-920 processors sit the new "Lynnfield" 2.93-GHz Core i7 870 and 2.8-GHz Core i7 860 processors. The brand-new, 2.66-GHz Core i5 750 CPU is a Lynnfield chip as well, but we'll get to that odd duckling further below.

Technology Differences
Intel took a big leap forward in the design department when it launched Core i7 900-series processors last November. Just a few of these included a new triple-channel memory controller integrated into the chip, a new QuickPath Interconnect system to replace (and improve upon) the front-side bus architecture of old, and the return of hyperthreading that split the chip's four physical cores into eight virtual cores for increased system performance. As the Core i7 900-series chips were based on a new Intel X58 chipset and LGA1366 socket, aspiring upgraders had to invest in new motherboards to reap the benefits of the Core i7 900-series platform.
That part still rings true for the new Core i7 800-series and Core i5 CPUs--all three run on Intel's latest P55 chipset and LGA1156 socket, which necessitates a new motherboard purchase for use. What's changed, however, is that the Core i7 800-series and Core i5 CPUs each adopt different permutations of the fanciest of the Core i7 900-series' features.
All three chips have dropped down from a QuickPath Interconnect and triple-channel memory controller to a Direct Media Interface and dual-channel memory controller. But don't freak out; This is more a loss of future-proofing than anything else given the minute performance differences between current dual- and triple-channel memory configurations.
An integrated PCI Express graphics controller on the Lynnfield CPUs can either deliver 16 lanes of bandwidth to a single PCI Express 2.0 videocard or split this connection into two x8 lanes for an SLI or CrossFire setup. Although it's a cut from the full 32 lanes (for a dual 16x or quad-8x configuration) provided by Core i7's X58 chipset, the bandwidth reduction should only affect those crazy enough to SLI or CrossFire dual-GPU videocards on a Lynnfield setup.
Turbo Boost: Automatic Overclocking

The new Core i7 800-series CPUs and the Core i5 750 still support the same automatic overclocking functionality, or Turbo Boost, as the Core i7 900-series processors. However, this feature has been jacked up on the newer chips. Core i7 900-series CPUs will only increase their multipliers to a maximum of two additional steps according to system demands (effectively taking a 3.33-GHz processor to 3.6-GHz depending on how many cores are in use). The new Lynnfield processors are able to jump up five multiplier steps for the 800-series chips (taking a 2.93-GHz processor to 3.6-GHz) and four for the Core i5 750 (2.66-GHz to a maximum 3.2-GHz).
Performance
Both Core i7 800-series processors support hyperthreading the same as their Core i7 900-series brethren. The Core i5 750 does not-its four physical cores are all that will appear in your operating system's task manager. Even so, the CPU's noteworthy performance makes it an excellent value for its roughly $200 price. We only saw a performance difference of 5 percent between the Core i5 750 and the roughly $555 Core i7 870 (based on WorldBench 6 testing of the two CPUs on identical system builds). In fact, the Core i5 750's score of 127 falls right around the scores set by competing Value and Power PCs that use Core i7 920 processors.
Test Bed: Intel DP55KG Motherboard, 4GB DDR3 1333 RAM, ATI Radeon HD 4890 graphics, 2x Seagate ST3750630AS hard disks (Raid 0), Windows Vista Ultimate 64 bit Service Pack 2
So where does that leave the Core i7 870? Given that its price is almost identical to that of the high-end 3.06-GHz Core i7 950 CPU, a processor that natively runs faster than the 2.93-GHz Core i7 870, it's difficult to see the compelling reason to pick up this chip. The Turbo Boost feature of the Core i7 870 does ultimately beat the speeds of the Core i7-950's, but for the enthusiast market, the increased memory support and bandwidth for multi-GPU setups might not be worth giving up. The Core i7 860 is more reasonably priced at $285, provided you can make sufficient use of its hyperthreading functionality.
It remains to be seen just how far the Core i7 800-series CPUs will overclock compared to the Core i7 900-series chips-the lower power draws of the 800-series processors could make quite a difference in this area. As for the Core i5 750, this chip looks to be a solid winner for those looking to dip their toes into the Nehalem platform without breaking the bank-given Intel's dramatic price points, that's always a strong possibility.

Inside Intel's Next-Gen Processors
Here’s how the new Core i5 and i7 'Sandy Bridge' chips--which bake graphics hardware into the CPU--are redefining PC performance.
By Jason Cross and Nate Ralph, PCWorld Feb 28, 2011 8:30 am
Intel rang in 2011 with its second-generation Core processors, promising vastly superior performance, better graphics capabilities, and improved energy efficiency. How much of a difference can a new CPU generation really make? If our tests of the first systems to use these revamped CPUs are any indication, the answer is "quite a lot." The new processors--formerly code-named Sandy Bridge--deliver stronger performance than their predecessors did, and at palatable prices.
Intel's integrated graphics have come a long way, too, with support for 3D Blu-ray and smooth playback of 1080p content. But video game fans shouldn't toss out their discrete graphics cards just yet--the graphics processors built into the new CPUs stumble on many modern titles. Bad news for upgraders, too: Intel has reworked the socket for the platform, so if you're looking to upgrade aging hardware, you must also factor a motherboard purchase into your budget.
The second-gen Core launch was not without hiccups. In late January Intel issued a recall of Sandy Bridge's 6 Series chipset due to a design flaw. According to Intel, this flaw in the motherboard chipset would cause performance of the SATA ports to degrade eventually.
Despite those concerns, Intel's new hardware remains a force to be reckoned with. If you're considering a new desktop or laptop with an Intel processor, chances are good that it'll be a Sandy Bridge model. We'll help you understand the strengths and weaknesses.
New CPU Features
The new CPUs retain the Core i3, Core i5, and Core i7 monikers that Intel has used for a few years, but the naming scheme is a bit misleading: These processors have a whole new architecture, and aren't simply a revision.
The company optimized and enlarged the caches for "micro-ops" used in the CPU, allowing for more-efficient, faster handling of tasks. Performance for AES encryption and SHA-1 hash operations is improved. A new set of vector extensions (called AVX) promises to rev up performance in some data-intensive applications, once they have been optimized to use the new instructions. And a new ring bus enables faster communications between cores and the integrated graphics processor.
Intel has made technical changes within the CPU cores, as well, most of which are of interest only to coders and compiler developers. What you need to know as a consumer is this: Performance should be better in just about any application that relies heavily on the CPU.
PCWorld Labs results showed considerable performance gains when comparing Sandy Bridge systems with first-gen Core PCs that are only a few months old. For instance, we saw a 13 percent increase in performance between a system with the new Intel Core i5-2500K and a similarly equipped six-month old PC sporting Intel's first-gen Core i5-650. The divide widens when vendors overclock the CPU. An $850 desktop with an overclocked Core i5-2500K cruised through tests 20 percent faster than a $2000 PC with an overclocked Core i5-655K.
Our initial testing demonstrates that the new Core processors allow users to do quite a bit more for less, and performance will only get better as tools and libraries are updated to allow applications to make better use of the features.
Enhancements to Intel's Turbo Boost technology will let the new Core CPUs run at higher clock speeds more often. The automatic speed-boosting feature used to work only if one or two of the cores were active while the others were idle. Now, if conditions are right, it can operate even when all cores are busy, and it can also boost the speed of the graphics processor a bit, if necessary.
Better Graphics and Video
If you were disappointed with the integrated graphics and video performance of past Intel processors, you'll be thrilled to know that this is probably the most improved aspect of the new chips. High-definition video plays well, and the 3D graphics are fast enough for modest games. With the previous Core i3, i5, and i7 processors, Intel incorporated integrated graphics directly into the CPU package. It was technically a separate chip on a different piece of silicon, and the results left us unimpressed: High-def video often stuttered, and PC gaming was pretty much a lost cause.
With Sandy Bridge, Intel has incorporated the graphics processing unit onto the same silicon as the CPU cores. The GPU communicates with the CPU cores along the high-speed ring bus and shares the L3 cache with the CPU cores. This GPU is compatible with Microsoft's DirectX 10.1; it is also dramatically faster than previous Intel integrated graphics. And as noted, the GPU can take advantage of Turbo Boost, giving you a little extra graphics kick right when you need it most.
All of the laptop versions of the new chips have a graphics processor with 12 execution units, while some of the desktop versions will use a cut-back version with 6 execution units and others will have the full 12. Unfortunately, you have no immediately obvious way to distinguish the two, but don't worry: The processors with fewer execution units are meant for either very low-cost systems or high-performance systems that will use a dedicated graphics card and circumvent the integrated graphics entirely.
Performance of the new graphics chips is impressive compared with what we've seen from Intel, but it's still not good enough to please seasoned gamers. For example, you can play modern titles such as Starcraft II smoothly, provided that you don't turn the resolution up too much or enable the highest graphics settings. Any gamer will want to pair their new Intel CPU with a good Nvidia or AMD graphics card. Still, the ability to handle such games at all is a big step forward for Intel.
GPU-accelerated features in upcoming Web browsers (such as Firefox 4 and Internet Explorer 9) work, too, resulting in smoother and more fluid Web browsing on cutting-edge sites.
Video processing is significantly improved with the new CPU, which offers better decoding of the MPEG-2, MPEG-4, and VC1 video codecs and fully supports 1080p Blu-ray playback (even 3D Blu-ray movies) at smooth frame rates. This enhanced video decoding, along with the improvements to the CPU cores, makes for superior performance in converting files from one video format to another. In our testing, we converted a 10-minute-long video clip into various formats on a wide variety of PCs. The revamped integrated graphics consistently finished the task at rates between 50 percent and 70 percent faster than the older Core processor; the new chip's results were also just a few seconds behind those of a $300 graphics card.
Impressive Energy Efficiency
All eyes are on energy efficiency these days, and the trend has not escaped Intel's notice. Despite the remarkable performance of the new processors, they tend to sip less power than the older CPUs do. In desktop PCs and all-in-ones, that translates to cooler and quieter systems and a slightly lower power bill; in laptops, it means longer battery life.
How much power a PC consumes depends on everything from the power supply to the key components to the brightness and efficiency of the display. It's therefore hard to draw direct comparisons. Still, our initial lab results are promising. When we compared PCs based on their WorldBench 6 scores, those with older Core CPUs used 57 percent more energy than our Sandy Bridge test platforms did to achieve the same results.
What to Buy
If you're in the market for a new PC, make sure that it carries one of Intel's new Core CPUs. The exceptions are netbooks and small, inexpensive ultraportable laptops--the Sandy Bridge chips aren't aimed at that PC category, and we're satisfied with the results from AMD's Fusion processors in such PCs. (For a closer look at those chips, which also combine a CPU and GPU, see "AMD Finally Ships Fusion Processors.")
How do you know whether you're getting one of the new processors? Look to the model number: The new CPUs are still called Core i3, Core i5, and Core i7, but those names are followed by four digits starting with a "2." A Core i7-2600K is new, for example, while a Core i7-970 is older. The quad-core models came out first, and the dual-core versions are arriving now; the latter should be less expensive and require less power, which means they'll fit into smaller and more-affordable laptops and desktops.
