Why you can trust TechRadar
Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Today is Intel Core i7 day. You’ll find lots of coverage of the new processor and the X58 chipset that supports it right here. We have everything from technical analysis so hard core it will make your brain boil to benchmarks of a literally record breaking machine based on the fastest Core i7 chip of all.

It’s a ridiculously impressive new processor, so it’s well worth getting to grips with all the new technology. But if what you really want is a quick guide to the chip itself — what makes it tick and how quick it is — read on.

The big news with Core i7 is improved multi-threaded grunt. To pull that off, Intel has created a much more elegantly architected CPU with added on-die features. Most of what used to be found in the northbridge chip on the motherboard has now been integrated into the Core i7’s own silicon die.

That includes the memory controller and much of the system I/O. The latter takes the form of the new uber-wide Quick Path Interconnect (QPI) that can shunt over 25GB in and out of the Core i7 every second. The idea is to provide more bandwidth to feed all those data hungry execution cores.

Unprecedented levels of raw bandwidth

And boy, do those cores get fed. Thanks to the addition of an extra memory channel — for a grand total of three — Core i7 packs an unprecedented 18GB of raw bandwidth. That’s literally three times as much as previous Intel processors.

Of course, AMD’s CPUs already have on-die memory controllers, but with only two channels and no support for DDR3 they typically only enjoy about half the bandwidth of Core i7. Incidentally, like AMD’s quad-core Phenom chip, the Core i7 is a truly monolithic, single-die processor. No longer will Intel bodge up quad-core processors by cramming a pair of dual-core chips into a a single processor package.

Along with the added on-die features, Intel has revved its latest processor with further features designed to give a boost to both old fashioned single-threaded applications and the latest highly-parallelised programs such as media encoding.

HyperThreading returns

The biggest headline grabber is the re-emergence of HyperThreading. It’s a feature last seen on the Pentium 4 Netburst CPU family and allows each core to crunch two software threads simultaneously for improved multi-threading and multi-tasking performance.

Since all Core i7 are quad-core chips, that means you’ll see no less than eight logical processors when you fire up Windows Task Manager. That’s a pretty sexy sight.

Next up is Turbo Mode. The short version of the Turbo Mode story is the ability to overclock individual cores according to work load. The aim is to make the most of the thermal limits of the chip when only one or two cores are under heavy load. Whatever the advertised clock frequency of a gvien Core i7 is, add 266MHz to that and you have the top speed a single core can run at.

Raw performance

Intel has also tweaked the cores themselves in a number of areas, including the addition of a few new SSE instructions for extra multi-media goodness and a new three-level cache memory hierarchy.

And for the record, all those architectural changes also bring a new processor socket, known as LGA 1,366. A new motherboard is therefore a bare minimum requirement to get in on the action.

As for the specifications of the Core i7s available at launch, there are three models. The entry level chip is the 2.66GHz Core i7-920, yours for £200, or perhaps a touch less. Next up is the 2.93GHz 940 processor, likely to sell for £400.

Topping things out is the inevitably expensive 965 Extreme Edition. It costs a cool £1,000, runs at 3.2GHz and adds a few overclocking-friendly features such as an unlocked multiplier. All three chips have 8MB of L3 cache and support up to 24GB of 1,066MHz DDR3 memory.

Exceeded expectations

But what about performance? In truth, our expectations weren’t all that high. Mainly, that’s because Intel’s existing Core 2 processors are so damn good, it was hard to imagine anything significantly bettering them much less blowing them away.

Of course, the Core i7 cares not a jot about our preconceptions. In our multi-threaded benchmarks, it duly proceeds to beat the Core i7 to a bloody, whimpering pulp. It’s around 60 per cent quicker in the X264 video encode test than the best Core 2 processor, for example. That’s almost silly.

While its superiority isn’t always that spectacular, a performance advantage of around 40 to 50 per cent is typical in most multi-threaded applications including image rendering and media encoding of various types.

As for how AMD’s Phenom compares, it’s an absolute massacre. Intel’s finest is now often twice as quick as the best AMD can deliver.

That said, the Core i7’s single-threaded performance is a bit less impressive. It seems the individual cores aren’t a major advance on the Core 2 architecture. Likewise, it’s a little disappointing to note that power consumption has gone up a fraction.

We had been lead to believe that greater feature integration would have the opposite effect. Finally, HyperThreading appears to occasionally have negative effect on performance when only a handful of CPU-intensive threads are being processed.

But those reservations are pretty small beer compared to the performance smörgåsbord the Core i7 cranks out most of the time.

3DNews Technologies and IT market. News processors Intel introduced the 10-core Core i7-695…

The most interesting in the reviews


05/31/2016 [09:20],

Anton Testov

Intel Corporation on Tuesday announced the long-awaited Core i7 Extreme Edition processor family based on the Broadwell-E architecture. The flagship of the new lineup will be the Intel Core i7-69 processor50X, the company’s first 10-core desktop processor. The new CPUs won’t just improve performance levels over their predecessors with more cores and architectural improvements. New items will raise the entire “extreme” Intel platform to a new level, both in terms of features and in terms of price.

Intel Core i7-6950X: Key Features

A bit of history

In the past two decades, a category of users has emerged who lack the power of modern desktop processors, but who for some reason do not want to switch to server solutions like Intel Xeon. Such users not only play the most advanced computer games, but also use demanding professional applications. Moreover, they are not against overclocking the system, as well as its adjustment to specific tasks. To meet the needs of such customers, AMD and Intel back in 2003 released special extreme versions of their processors — FX and Extreme Edition. Since it is not economically feasible to create special chips with an eye on enthusiasts, the first FX and Extreme Edition were, in fact, server processors with large L2 caches and increased frequencies, which had no overclocking restrictions.

Evolution of the Intel Extreme Edition

The experiment with repurposing server processors turned out to be successful: CPUs proved their popularity, and users were able to pay $999 per chip. Subsequently, AMD and Intel began to develop special «extreme» platforms for enthusiasts (Intel calls such HEDT — high-end desktop) to offer something more than the overclocking capabilities of relabeled server CPUs. The processors themselves have also evolved, which, although they remained server-oriented in their purpose, have the ability to fine-tune the power supply of the cores, memory controllers and PCI Express, support for special modes of operation with DRAM, and much more. At some points, both AMD and Intel offered platforms based on two microprocessors to enthusiasts, but the latter did not take root due to the high price and operating features. In recent years, AMD has withdrawn from the race, and the development of the «extreme» platform for desktop PCs has remained entirely the prerogative of Intel. Despite the lack of competition, the evolution of such processors continues at a good pace, being slowed down only by the introduction of new technological processes, which happened in the case of the 14-nm CPU.

Intel Broadwell-E: What’s new?

Intel Broadwell-E, a new family of processors for enthusiasts, increases the core count of the flagship to 10, and also offers additional functionality not found in its predecessors and not available in Intel Xeon chips. Moreover, Intel believes that innovations increase the attractiveness and performance of new chips so much that they create prerequisites for a significant increase in prices for new CPUs compared to their predecessors. Thus, the flagship of the family will cost more than $1,700, an unprecedented price for an Intel-made CPU for single-processor systems. In fact, the new Intel Core i7 Extreme Edition processors are now significantly more expensive than similar Intel Xeon chips designed for servers. What is the reason for such a high price? Let’s see!

Intel Core i7-6950X: New Overclocking Options

The Broadwell-E family of microprocessors are Intel’s first «extreme» chips manufactured using 14 nm technology. The thin manufacturing process, coupled with a heat dissipator soldered to the crystal, increase the overclocking potential, which means that many Broadwell-Es will be able to boast frequencies of 5 GHz and higher without the use of extreme cooling. All processors are unlocked and compatible with motherboards based on the Intel X9 chipset9 and LGA2011-3 connectors. Among other architectural improvements Broadwell-E compared to its predecessors, the following is announced:

  • Formal support for DDR4-2400 type memory, as well as the ability to further increase the clock frequency of DRAM.
  • Support for Intel Turbo Boost Technology 3.0 — Automatically maximizes clock speeds when a large number of cores are loaded.
  • The ability to overclock each core individually, which will make it possible to increase performance in single-threaded (or poorly scaling from the number of cores) applications by setting high maximum frequencies for the most loaded cores.
  • Possibility of power management of the processor system agent (known in the case of Intel terminology as uncore), which will improve the stability of systems during overclocking when the frequencies of the PCI Express and DMI buses are modified, which will maximize the CPU clock frequency.
  • AVX ratio offset correction.

The last four features were not available on previous generations of Intel processors and are not available on Xeon E5 v4 (Broadwell-EP) processors. Thus, Intel very clearly delimits the scope of its chips.

Sixth Generation Core i7 Extreme Edition Family

Intel Core i7-6800/6900 Broadwell-E Generation CPU family includes four CPUs: two six-core (Core i7-6800K, Core i7-6850K), one eight-core (Core i7 -6900K) and one ten-core (Core i7-6950X). When Intel released the first Intel Pentium 4 Extreme Edition processor based on the Gallatin core 13 years ago, it was the only «extreme» CPU in the company’s lineup. Subsequently, the corporation expanded the Extreme Edition family to three, and now added a fourth model. This expansion signals an increase in demand for high-performance desktop solutions, which the world’s largest CPU manufacturer is trying to capitalize on.

Intel Core i7-6950X: A look inside

The flagship of the new family is the Intel Core i7-6950X processor, which has 10 Hyper-Threaded cores at 3 GHz, 25 MB L3 cache, a quad-channel DDR4 memory controller , as well as a PCI Express 3.0 bus controller with support for 40 lanes. Intel’s highest performing desktop processor will cost $1,723, which is more expensive than the Core 2 Extreme QX9775 in 2009 ($149).9), but cheaper than Pentium II 300 MHz in 1997 ($1981).

Other models in the family have fewer cores and smaller cache sizes, but boast higher clock speeds. However, all of them are more expensive than their predecessors of previous generations, which indicates the manufacturer’s confidence in the attractiveness of their new products.

Intel HEDT more expensive than Xeon?

It is interesting to note that the new Intel Core i7-6950X processor is significantly more expensive than any Intel Xeon E5 v4 with 10 cores. In particular, the company evaluates the Xeon E5-2630L v4 (1.8 GHz), Xeon E5-2630 v4 (2.2 GHz) and Xeon E5-2640 v4 (2.4 GHz) chips at $612, $667 and $939. Of course, due to relatively low clock speeds, such processors will be slower than the new flagship of the Extreme Edition family and will not be able to be overclocked. However, if someone needs a 10-core processor for professional use, then the Xeon E5 will cost less than the Core i7 Extreme Edition. What’s more, for those who need even more cores, Intel is offering the Xeon E5-2680 v4 with 14 cores at 2.4GHz and 35MB of L3 cache for $1,745. However, none of the Xeon chips can boast technologies like Turbo Boost 3.0 and the ability to overclock individual cores to increase performance in single-threaded applications. To enjoy the speed in the latter, you will need the new Core i7 Extreme Edition.

Intel X99: Key characteristics of the platform

Thus, if we consider only the Broadwell-E family, it is obvious that the Intel HEDT platform is becoming more and more expensive, and the price of some of its components — processors and motherboards — often exceeds the prices of server CPUs and platforms, which is quite an unprecedented situation. However, do not despair. Intel will continue to sell Haswell-E generation Intel Core i7-5800/5900 processors, the younger ones do not lose their attractiveness.

Along with the release of Intel Core i7-6800/6900 CPUs of the Broadwell-E family, motherboard manufacturers will release a new generation of motherboards based on the Intel X99 chipset. The novelties will feature Thunderbolt 3 support, as well as a number of other improvements, such as a reinforced processor power system and increased overclocking potential. However, the most radically improved models, such as the ASUS ROG Rampage V Edition 10, will also feature an incredible price.

Intel Core i7 | it’s.

.. What is an Intel Core i7?

Intel Core i7 is Intel’s x86-64 processor family. This is the first family to use the Intel Nehalem microarchitecture. It is also the successor to the Intel Core 2 family. All five processor models are quad-core. [1] The Core i7 ID also applies to the original [2] [3] processor family, with the working name Bloomfield , [4] launched in 2008 [39 1011] The name Core i7 indicates the generation of the processor (Core 2 Duo/Quad/Extreme were 6th generation) and continues to use the successful series of brands: Core 2 and Core .

Core i7 features

Core i7 family logo

This microarchitecture contains a number of new features. Here are just some of them compared to Core 2 :

  • Processors for LGA 1366 socket have FSB replaced with QPI (QuickPath). This means that the motherboard must use a chipset that supports QuickPath. As of April 2010, only the Intel X58 chipset supports this technology.
  • The

  • Core i7 is not designed for multi-processor motherboards, so there is only one QPI interface.
  • LGA 1156 socket Core ix processors do not use the QPI bus. It is not required due to the complete absence of the north bridge (fully integrated into the processor).
  • The memory controller supports up to 3 memory channels, each with one or two DDR3 DIMMs. Therefore, motherboards for Core i7 support up to 6 memory sticks, and not 4, like Core 2.
  • Only supports DDR3 memory.
  • Single-chip device: all four cores, memory controller, and cache are on the same chip.
  • Support for Hyper-threading, which results in eight virtual cores. This feature was introduced in the NetBurst architecture, but was dropped in Core.
  • 8MB L3 cache.

Note: The Intel Core i7 975 Extreme Edition and 950 processors have been released to replace the 965 Extreme Edition and 940 processors, respectively, will gradually replace them from the price lists, available for order from April 7, 2009. The price is given per unit in a batch of 1000 pieces.
Note: The i7 800 series processors do not have a QPI bus, this is due to the fact that the processor completely absorbed the north bridge, therefore neither the FSB nor the QPI bus is required.
Note: A DMI bus is present between the northbridge and southbridge counterparts on both QPI and DMI bus systems
Note: The Intel Core i7 920 is being discontinued and replaced by the faster 930.

Performance

A system with a single 2.93 GHz Core i7 940 processor was used to run the 3DMark Vantage benchmark program and achieved a processor subsystem score of 17966 conditional points. [13] One 2.66 GHz Core i7 920 gave 16294 points. And one 2.4 GHz Core 2 Duo E6600 gave 4300 of the same conditional points. [14]

AnandTech tested the Intel QuickPath Interconnect Technology (version 4.8 GPU/s) and estimated copy throughput using 1066 MHz DDR3 memory in tri-channel mode to be 12.0 GB/s. And a 3.0GHz Core 2 Quad system using 1066MHz DDR3 memory in dual-channel mode achieved 6.9GB/s. [15]

Overclocking (custom overclocking) will be possible in all released models of the 900th series together with motherboards equipped with the X58 chipset. [16]

Intel still hasn’t named the Lynnfield and Havendale processors. Since they are built on the Nehalem architecture, they may be named differently than Core i7 (Probably Core i5). These processors will use a different socket and support other chipsets that require a different motherboard design. [17]

Some Internet resources suggest that the Core i7 is less productive in games (due to the L3 cache, which has a higher delay before the L2 cache). In the tests performed Core i7 940 and QX9770 parity is observed (in 2 games the Core i7 940 won, in two more — QX9770, with a slight difference in the results) [18] .

In the Super PI 1M test, the Core i7 920 running at 2.66 GHz passed the test in 14.77 seconds, while the QX9770 (3.2 GHz) passed it in 14.42 seconds.

Facts

  • The protective cover of the processors consists of nickel-plated copper, the substrate is silicon, and the contacts are made of gold-plated copper.
  • Core i7 minimum and maximum storage temperatures are -55°C and 125°C, respectively.
  • The

  • Core i7 is capable of withstanding up to 934 N static and up to 1834 N dynamic loads.
  • The maximum heat dissipation of Core i7 processors is 130 W, in idle mode it is 12-15 W.
  • The efficiency of the standard Core i7 cooler drops sharply if the temperature inside the system unit exceeds 40 °C. [19]
