"Intel's Core i7-7700K is the fastest quad-core processor ever"
Pros
- Fastest unmarried-cadre functioning yet
- Strong multi-cadre performance
- Compatible with previous motherboards
- Early results are promising for overclockers
Cons
- Not a must-have upgrade
- Core i5 quad-cores remain the better value
Intel debuted the 7thursday-generation of Intel Core processor at IFA 2016, just its initial line was limited to simply dual-core mobile chips. Those looking for new desktop hardware were told they'd take to wait.
Now the wait is over. Intel'southward Core i7-7700K is here. It's the flagship of Intel's latest processor architecture, a quad-core behemoth that's aimed at enthusiasts, gamers, and workstation users.
That it will exist quick goes without saying, but the 7thursday-generation represents an undesirable change in step for Intel. It's the 3rd processor family congenital on a xiv-nanometer production process. Normally, Intel would move on to a smaller technique for this new generation, but the company'south ten-nanometer production has been delayed.
Has that hobbled the Cadre i7-7700K, Or is it a worthwhile upgrade? And tin it keep users excited nigh Intel hardware with AMD's Ryzen simply around the corner?
New processor, same as the sometime processor?
Intel's Cadre i7-7700K is like a son born to a family of blacksmiths in a medieval backwater. It'south a quad-core processor that supports overclocking just like its father, and its begetter before, and its father before. The lineage can be traced all the way back to the Core i7-2700K, which debuted in late 2011.
Not much has changed over the years – at least according to the specification sheet. The Core i7-7700K is a quad-core fleck with Hyper-Threading, which means information technology acts as if it were an eight-core processor. The base clock speed is 4.2GHz — up from 4GHz in the Core i7-6700K– and the maximum Turbo Heave speed is 4.5GHz — up from 4.2GHz. The scrap has the same 8MB SmartCache that tin exist found in every fleck in its lineage, going all the way dorsum to the i7-2700K. The thermal design ability is 91 watts, the same as its predecessor, and down only slightly from the i7-2700K.
The graphics solution, Intel's HD 630, is the same one establish in the Core i7-6700K. The same DDR4 memory is supported, though the maximum speed is now 2400MHz, an increase from 2133MHz. And the scrap uses the same LGA1151 socket as before.
That's a lot of similarities. Then, what has changed? There'southward just i major characteristic to point to; Intel's New Media Engine. The seventh-generation Intel Core chips included hardware decode back up for VP9 and HEVC ten-bit, with enables hardware decode of 4K. Intel isn't talking about this much with the Core i7-7700K, because it'due south a petty irrelevant. Its predecessor handled 4K video just fine, even if it was typically software decode. Still, it's expert to know the Cadre i7-7700K can handle 4K video with minimal processor load.
The new chipsets experience familiar, likewise
As usual, Intel has a new line of chipsets to go with its new processor. Though there's technically five new chipsets, consumers need simply pay attending to the Intel H270 and Intel Z270, the consumer-focused options. The quondam is a budget chipset, while the latter is for enthusiasts.
What separates them? It by and large comes down to PCI Express lanes and overclocking. The H270 tin can support up to 20 PCI Express 3.0 lanes on the chipset, while the Z270 has 24. And while the H270 and Z270 both include support for a PCI Express three.0 ane×16 slot for a graphics card, the Z270 lets motherboard builders split the lanes up amongst ii or three slots, for users interested in multiple-GPU setups.
Only the Z270 supports overclocking. That'south important for anyone because the Core i7-7700K, which is an unlocked chip designed to allow overclocking. If y'all purchase a i7-7700K, but pair it with a motherboard that uses the H270 chipset, y'all won't be able to overclock it.
For the most part, these new chipsets are identical to the H170 and Z170 that supported Intel's 6th-generation Core desktop hardware. The chief difference is 1 that's not of result until later this year – Intel Optane support. Optane is an all-new storage device technology that Intel says can offering speeds that crush the fastest solid state drive, and it's due out later on this yr. Only you won't exist able to apply it unless you lot have an Optane compatible motherboard.
While new chipsets flank the new hardware, the older H170/Z170 chipsets can accept new seventhursday-generation intel Cadre hardware, including the Core i7-7700K. This is enabled through a BIOS update from your motherboard manufacturer. Y'all can simply driblet in the new processor so long every bit y'all've updated BIOS beforehand.
On to the benchmarks
Enthusiasts have been negative about the prospects of the 7th-generation Core, and for good reason. It doesn't merits whatsoever notable advancement in either architecture or product process. That might lead you lot to call back the processor doesn't perform much better than its predecessor, the i7-6700K.
Then, every bit expected, the Core i7-7700K is underwhelm…await! Are those scores correct?
Indeed. According to GeekBench 3, the Core i7-7700K makes substantial improvements across the board. Its unmarried-cadre performance is 20 percent better than the Core i7-6700K, and sets a record in that test for processors at stock speed. Multi-cadre performance, meanwhile, shot up 18 percent compared to the i7-6700K.
This isn't Kaby Lake'due south first surprise. As we remarked in our review of the latest Dell XPS 13, the 7th-generation Cadre beats expectations. In that location, the Core i7-7200U proved virtually 15 percent quicker than the Core i5-6200U in GeekBench 3's unmarried-core examination, and was an incredible xxx percent better in GeekBench three multi-core.
In GeekBench three, the Core i7-7700K is 20 per centum quicker than the 6700K.
Handbrake also shows massive improvement. The Core i7-7700K transcoded our test clip, a 4K trailer of Elysium, to H.265 in five minutes, 45 seconds. The Core i7-6700K needed 8 minutes, 33 seconds. That's a major gain.
This doesn't make the i7-7700K the fastest processor in all tests. Equally you can see, the Core i7-6950X, which has ten cores, easily defeats the 7700K in multi-core tests. It's not exactly a off-white fight, though, as the 6950X'southward increased core count comes at an MSRP of $1,649. The Cadre i7-7700K is far more than practical, and actually wins in single-core benchmarks due to its college per-cadre clockspeed.
What about overclocking?
Nosotros didn't dive into overclocking for this review. It'due south not unimportant, merely a technically demanding and fourth dimension-consuming attribute. Frankly, we ran out of time by our publishing borderline.
With that said, we practice accept a information point. Bazaar PC builder Digital Tempest sent us a Velox gaming desktop ahead of the Core i7-7700K's launch. It arrived with a base clock speed of 5GHz, and was entirely stable at that speed. This is the highest stable speed we've e'er seen in a product desktop.
Neb Roberson/Digital Trends
Nosotros've tested numerous overclocked Core i7-6700K systems, and the fastest among them hitting 4.8GHz, only the bulk pushed no higher than 4.7GHz. Nosotros've also encountered numerous instances where the Handbrake exam crashed systems clocked at 4.7GHz, indicating even that overclock was not entirely stable, fifty-fifty if information technology was stable enough for everyday utilise.
That's promising. But we as well encourage skepticism. Early engineering samples are often best-example examples of hardware, so it's possible that most product hardware won't be equally capable. And overclocking, which pushes hardware to its limit, tin observe flaws non immediately axiomatic. Information technology'll take the overclocking customs a couple months to determine if 7thursday-generation Core is superior to its predecessor.
Warranty information
Intel boxed processors come with a iii-yr warranty confronting manufacturer defects. This does not protect against damage due to overclocking, as you might await, though Intel does in fact sell a "Tuning Plan" to protect against such damage.
AMD provides a similar warranty for its processors.
Our Take
At this indicate, everyone expects a new Intel Core processor to be a chip faster than its predecessor. That's true of the i7-7700K. Just its performance gain will surprise those preparing for the viith-generation to exist a disappointing, mid-wheel revision.
Is there a improve culling?
As Intel'southward flagship quad-core, the Core i7-7700K doesn't have a performance peer. AMD's Ryzen processor might provide some competition, simply information technology's not out, and likely won't be for a few months. The real question is whether yous need a processor this fast, as Intel's other quad-core fries are much less expensive.
How long volition it last?
A very long fourth dimension. This is a new processor, compatible with new chipsets. Many people still use the five-year-erstwhile Intel Core i7-2700K without complaint, and the Core i7-7700K will be useful for at least every bit long, if not longer.
Should you lot buy it?
Yes, if you're edifice or buying a new PC, or looking to replace the processor in a PC that'due south four years old (or older).
The main problem with the Cadre i7-7700K is ane that applies to its predecessors, too. It'southward expensive. The Intel bin price is $339, which ways retail prices volition likely exist in the $359-$379 range. That's a lot, and it drives the chip'due south value down.
Withal value isn't the 7700K's goal. Information technology's congenital to be the fastest quad-core processor sold to consumers, and achieves that by setting a tape for stock single-core operation. That makes it the obvious choice for enthusiasts in need of an upgrade.
