Intel’s 8-Core Mobile Tiger Lake-H, at 45 W, to Ship in Q1

Ever since the launch of Intel’s 11th Gen Core mobile processors, known as Tiger Lake, back in September, the chips' limited core counts have not gone unnoticed. At a time where its competition is leveraging 8 cores in the same space, Intel seems limited to only 4 in the same 15-28 W power window. At the time, Intel stated that the base Tiger Lake design was aimed to be scalable, and that double sized variants were in the works. Today Intel has confirmed that those double-sized parts will be coming in Q1, in the form of Tiger Lake-H.

Back at Intel’s Architecture Day 2020, lead architect Boyd Philips stated that even though the standard Tiger Lake UP3 design contained four cores and 12 MB of L3 cache, designs with double the L3 cache were in the works. This was instantly interpreted that double core-count versions of Tiger Lake were in the works, given that in the last generation the higher-powered mobile processor line-up had been left to older 14nm processors to fill the gap, and that Intel normally launches products for both 15 W and 45 W at the same time. We had been expecting a fast follow on, with a launch sometime later in Q3'20, but it would appear that Intel has pushed this out to Q1'21. Intel says that these processors will start production and ship in Q1, which likely means that the actual products will come to market in Q2.

Intel has confirmed that these parts will offer up to eight cores and sixteen threads, with a highlight being that the top variants will enable 5.0 GHz turbo frequencies on multiple cores. These processors will also have 20 lanes of PCIe 4.0, which will allow for a full PCIe 4.0 x16 link to a discrete graphics card and a single PCIe 4.0 x4 storage drive at the same time, while also having a separate link for the chipset and IO. We expect these processors to also support PCIe Resizable BAR. And, like their current quad core counterparts, these processors will also have Thunderbolt 4 native support, as well as Wi-Fi 6/6E support through an associated RF module.  

Intel traditionally has a number of overclockable H-series processors, known as HK, however the company has not explicitly stated if any overclocking SKU will make it to market. Typically these H-Series processors target the 45 W market, with a 35 W step-down option. Intel is also announcing today that it has moved its U-series processors, typically 15 W, up into that 35 W market as well (known as H35). We will start to see some overlap between the two, with higher frequency quad-core U-series processors up against eight-core H-series parts.

We wait to see exactly what specifications Intel will target with the new hardware. More detail to come.

    a little behind? dude, Ryzen 7 4800U on Lenovo Yoga Slim 7 literally has nearly twice the MT performance of i7-1165G7. come on, don't compare it with Ryzen 7 4700U, nobody sells i7-1165G7 from 599USD.

    "it is doing fine against AMD's latest 8 cores big lead in ST, just a little behind in MT"

    Check the benchmarks, I think you meant:

    "slight lead in ST, a colossal loss in MT"

    Still better than AMD's "we'll announce something". "Oh, we announced a date for an announcement." Or the latest "you're going to see more RDNA 2 cards in H1 2021".

    Shame that 8 core Tiger Lake won't be available socketed for z590. I get that Rocket Lake is needed due to limited 10nm capacity, but this would go toe to toe with Rocket Lake with lower power consumption, which would have been nice for a SFX system.

    Just buy a NUC. Tiger Lake U/H will be available.

    Waiting in the NUC11 Pro - which should be out any time now - won't be an H though - 1185G7 is the top spec for the upcoming NUCs - Maybe the Extreme (anything other than the 4.5"x4.5" form factor is tough calling it a NUC) will have the 45W 8C H.

    I just want G7 - of the almost 70 I have deployed - CPU is not the issue - the GPU is - only the most modern we have deployed can do dual 2560x1440 and can not do dual 4K without serious lags -as more of my employees move to dual monitors - this will be a welcome upgrade. TB4 is also massive - the Sonnet TB3 to SFP+(10Gb Ethernet transceivers) will allow me to finally use the fiber I installed when I built this building, and will also make max use of the SFP+ ports on our new Cisco Nexus Switches - and the whole new network in general.

    This is an objectively bizarre environment that you're describing.

  • Deicidium369 - Monday, January 11, 2021 - link

    with the 20 PCIe lanes, and integrated TB4 - would be comparable...

    The "limited 10nm cap" is an old meme - 3 full HVM lines - 1 is 10nm for Ice Lake SP - which is the 2 socket Ice Lake SP platform - 128PCIe4 lanes, 8Ch DDR4-3200ECC... and will be a ultra high volume launch - 2S is the bread and butter of the data center...
    2 line working with at least SF - if not 1 already gearing for ESF - The Golden Cove trio (Alder Lake Desktop, Sapphire Rapids Server and an unnamed EVO SOC) is the beginning of 1 arch for all 3 markets, and with Sapphire Rapids - 1 arch for 1-8 sockets. - which was the way it was before Cooper Lake/Ice Lake SP

    If it's not about limited capacity, then why aren't they doing it? Having lots of manufacturing lines isn't much help if your yields are still poor.

  • yeeeeman - Tuesday, January 12, 2021 - link

    Then why call the 35W, 4 core parts "i7"?
