Last week Intel recently updated its specifications for the 7th generation processors. In doing so, we can see several new Kaby Lake i3 SKUs coming to desktop, along with a few new KBL-U series SoCs for notebooks and a new Xeon E3-1285 v6 CPU, which matches the specification for Apples newest iMac. The full specification update from Intel is listed here

New Desktop Core i3 Kaby Lake CPUs

The existing lineup of Core i3 on the desktop has six models ranging from the i3-7100T to the Core i3-7350K. Like previous generations, all the parts have two cores and support hyperthreading, although Intel did shake things up with this generation by offering an overclockable Core i3, but also moving the lower-class Pentiums from plain dual core to dual-core with HT as competition. The main differences between the parts are core frequency (Core i3 has no Turbo), L3 cache, GPU Turbo and TDP.

7th Generation Core i3 and Pentium Desktop Processors
  Stepping Cores Freq L3 GPU Turbo
TDP List
Core i3-7350K B-0 2 / 4 4.2 GHz 4 MB 1150 MHz 60W $168
Core i3-7340 S-0 2 / 4 4.2 GHz 4 MB 1150 MHz 51W *new
Core i3-7320 B-0 2 / 4 4.1 GHz 4 MB 1150 MHz 51W $149
Core i3-7320T S-0 2 / 4 3.6 GHz 4 MB 1100 MHz 35W *new
Core i3-7300 B-0 2 / 4 4.0 GHz 4 MB 1100 MHz 54W $138
Core i3-7300T B-0 2 / 4 3.5 GHz 4 MB 1100 MHz 35W $138
Core i3-7120 S-0 2 / 4 4.0 GHz 3 MB 1100 MHz 51W *new
Core i3-7120T S-0 2 / 4 3.5 GHz 3 MB  1100 MHz 35W *new
Core i3-7100 B-0 2 / 4 3.9 GHz 3 MB 1100 MHz 51W $117
Core i3-7100T B-0 2 / 4 3.4 GHz 3 MB 1100 MHz 35W $117
Pentium G4620 B-0 2 / 4 3.7 GHz 3 MB 1100 MHz 51W $86
Pentium G4600 B-0 2 / 4 3.6 GHz 3 MB 1100 MHz 51W $64
Pentium G4560 B-0 2 / 4 3.5 GHz 3 MB 1050 MHz 54W $52

According to the updated document, the new CPUs are the Core i3-7120, Core i3-7120T, Core i3-7320T, and the i3-7340. These parts do not have prices listed but are labeled as a new 'S-0' stepping compared to the previous B-0 stepping parts. Aside from this, they are either lower power parts (the T CPUs) or small MHz bumps. 


New Laptop Kaby Lake-U 15W CPUs

Aside from the Desktop i3 parts, Intel is filling out some of the mobile SoCs as well. Intel's 15W line is commonly used in fast but thin notebooks, but typically needs an active fan to keep cool (unless you have a Huawei Matebook X). Intel uses its 15W moniker for Core i3, Core i5-U and Core i7-U parts, which are all dual-core with hyperthreading, but differ in base frequency, turbo frequency, L3 cache and GPU frequencies. 

Additional (7/17): We've been told by Intel that these SKUs were mistakenly added to the datasheet in question, and are not finalized for release (if they will be released at all). Specifically, we were told:

The SKUs listed are not intended to be in the market anytime soon. A couple of them will actually never become products.

Additional (7/17): These SKUs were removed at the request of Intel, as they will not be coming to market (and they've apparently already had requests from customers, it seems). We've requested that Intel shares with us info with us if new U SKUs are planned to come to market in the future.

New Intel E3-1200 v6 Series Xeon: The New iMac CPU?

When Intel launched the E3-1200 series, we commented that the last CPU in the stack pushed the boundaries for price: The E3-1280 v6 was $612, and only a small bump in frequency over the E3-1275 v6. Now Intel is set to launch the E3-1285 v6, which again bumps up the frequency - becoming a mix of the top Core i7 parts. 

7th Generation Kaby Lake Xeon E3-1200 v6 Processors
  Cores Base Turbo L3 GPU TDP List
Xeon E3-1285 v6 4 / 8 4.1 GHz 4.5 GHz 8 MB HD P630 91 W *new
Xeon E3-1280 v6 4 / 8 3.9 GHz 4.2 GHz 8 MB None 72 W $612
Xeon E3-1275 v6 4 / 8 3.8 GHz 4.2 GHz 8 MB HD P630 73 W $339
Core i7-7700K 4 / 8 4.2 GHz 4.5 GHz 8 MB HD 630 91 W $350
Core i7-7740X 4 / 8 4.3 GHz 4.5 GHz 8 MB None 112 W $339

The E3-1285 v6 has been earmarked as the new high-end processor in the iMac, and we expect that it would likely cost a pretty penny given the price of the E3-1280 v6 just underneath it.

    $5000 can get you a lot in a pc

    Yeah, that bit is ridiculous. For a site that claims to avoid reporting on rumors, I'm not even sure what to say here.

    Since the WWDC keynote on June 5, Apple's website has had tech specs for the iMac Pro which clearly list 8, 10, and 18-core Xeon options with turbo up to 4.5 GHz and up to 42MB cache. Also, memory configurations from Apple include up to 128 GB DDR4-2666 EEC RAM. So there is no way Apple is using E3-1200 v6 Xeons in the iMac Pro.

    So Ryan, you should really take down that link to Digitimes, which appears to be behind a paywall unless hot-linked directly from Anandtech, and is an unsubstantiated and inaccurate rumor from April (before the WWDC announcement). Unless someone's getting paid to keep it there.

    AMD's lineup is refreshingly simple in comparison. Yet leaves little to be desired.

    With Ryzen onslaught, intel complete desktop/HEDT feel boring as hell.

    With Ryzen 5 1400-1500X offering about 90% of a i7 6700 for half the price any dual core+ht above $70 simply should not exist.

    Now Ryzen 3 between $109-129 even worse for intel i3 line.

    Ryzen really did a mess of intel pricing, profit, marketshare plans for the next 3 years.

    For the price of a Core i3-7320 itself, I can easily get a complete i5-3470 refurb office PC that is still faster in MT and able to take in and run a SSD and 1050 Ti. I really see no reason buy and build new Intel rigs other than the 7700K these days.
  • Lolimaster - Saturday, July 15, 2017 - link

    Why a 7700K, 1500X is basically that at half the price, and once you go to 1440p+ the difference in IPC (5-7%) for gaming in basically gone.

    1500X + 2xRX570 or just a puny 1050ti + 7700K
    1500X + 1060 6GB or just a puny 1050ti + 7700K
    1500X with 1080 or just a puny 1060 + 7700K

    No desktop Iris? Straight to the trash these CPUs go...
  • Ej24 - Saturday, July 15, 2017 - link

    I love the low power revisions Intel is able to bring to the table midway through a product cycle. 3.6ghz on all cores at 35w. That's nuts considering that takes into account the igpu too. My haswell i3-4130t is also 35w but maxes out at 2.9ghz. My i7-4790T is still probably my favorite cpu. Max single core turbo up to 3.9, all core turbo around 3.5ghz and only 45W. While Intel hasn't made huge gains at the top end, their mobile and low power desktop offerings are still pushing the envelope in perf/watt.

    You can custom Ryzen to whatever efficiency you want.

    Ryzen 7 1700 achieves 800pts in CB R15 with just 35w once you downclock and undervolt it.

    Ryzen 7 1700 limited to 35w = i7 6700 65w
