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.

    The base and turbo speeds you have listed for the 7700K are wrong, as is the base speed for the 7740X. It should be 4.2 GHz, 4.5 GHz and 4.3GHz respectively.

    I sure hope that Xeon E3-1285 v6 is priced in that 300$ range... insane how +100 mhz = double the price
  • extide - Friday, July 14, 2017 - link

    Considering the model below it is $612, I wouldn't count on it being anywhere near $300. It's going to be at LEAST $612

    What is the iMac you are referring to in the article? All iMacs are listed as having i7 or it CPU. The only one I know of having a Xeon is the upcoming iMac Pro, but given they say it'll have up to 18 cores I doubt it'll have an Xeon E3.
  • melgross - Friday, July 14, 2017 - link

    The new iMac Pro due out in December is slated to have up to an 18 core Xeon, ECC RAM, up to 128GB.
  • Santoval - Friday, July 14, 2017 - link

    "Up to 18 cores" means the lowest end of the series can easily start with 4 cores.
    It is a Xeon, after all, not an i7.. /s
  • Glock24 - Friday, July 14, 2017 - link

    Yes, but different socket, different chipset.

    BTW, Xeon E3s are rebranded i5/i7 CPUs with ECC enabled. They even use the same socket and until recently could even use the same chipset. Intel decided to make the market segmentation even more pronounced and since E3 v5 (Skylake) you need a server chipset for the CPU to work. Before then you could put an E3v4 on an H87/Q87/Z87 motherboard.
  • PixyMisa - Friday, July 14, 2017 - link

    They announced that it will start at 8 cores. So definitely not using an E3 Xeon.
  • hishnash - Monday, July 17, 2017 - link

    No apple have been very clear there are 3 different options: 8, 10 and 18 cores

    the lower end $5000 will be 8cores 16 threads.
