New Intel Kaby Lake Core i3 Processors: i3-7340, i3-7320T, i3-7120T, i3-7120
by Ian Cutress & Joe Shields on July 14, 2017 4:00 PM EST
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 Frequency |
TDP | List Price |
|
| 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 Price |
|
| 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.

Intel simply can't touch Ryzen efficiency, AMD's efficiency goes to sick levels when you relax the clock and voltages.Hurr Durr - Monday, July 17, 2017 - link

I cannot think of any reason why 2C/4T processor should even exist. Quad-Core should be the norm.hishnash - Monday, July 17, 2017 - link
The Xeon E3-1285 v6 is NOT the cpu that will be used in the iMAC PRO, apple have said the low-end iMac PRO (starting at $5000) will have an 8core 16thread Xeon.the E3-1285 v6 is only 4cores.

I think apple execs are hitting their head hard about choosing intel for their soon to be high performance imacs.Just imagine the profits of just using a $999 1950X offering 40% more than the intel offering at the same price. Or just stick to the 1950X and squeeze even more profits while keeping the premium price.
Apple may change the iMac pro to threadripper and Ryzen, it's happening boyz.

i3 kaby lake IS with really high frequency with Very capable 4k graphics for normal non-gaming/non g-heavy uses.i3 IS FASTEST single thread performance of all time. Why do you lower expectation? Two FAST COREs is enough for developers for example. I myself bought $400 plus some Desktop which IS much faster and more productive than any laptop. It is i3 with 128 GB ssd and 1 TB hdd.. Don't forget Windows 10 is made for 2 cores and office 2017 is made for single thread. Microsoft made Directx 12 more cores, but didn't get very well results in real world.
Ryzen 3 is equal to i5 ivy bridge in performance, though it IS with faster RAM and uses more power than them, so, efficiency of AMD is nonsense, it is only HW-Acceleration in that benchmark (at least, 16 cores/threads is much easier to make for a performance point, but I heard it is HW-accelerated and it is not for core count in cinebench r)....
Thanks!

Ryzen already demolishes Skylake in performance per watt, if you relax Ryzen with lower clock speeds and SMT off like on Ryzen 3, the efficiency gets even higher.You need 2 fast cores, get the Pentium 4560... oh wait...

All in line with Ryzen having around 93% of Skylake IPC or 8-5% less IPC depending on the memory speed.
