The specifications of Intel's unreleased 14th Generation T-series CPUs have been leaked by hardware sleuth @momomo_us on X. Expected to come out early next year, these refreshed T-series CPUs apparently offer higher clock speeds than 13th Gen models while retaining the typical 35-watt TDP of the T-series.

Core i3-13100T4 (4P)4.2 GHz35W
Intel Core 300T2 (2P)3.4 GHz35W
Intel Core 3002 (2P)3.9 GHz46W

The list includes a T-series variant of nearly every desktop Raptor Lake Refresh CPU, including budget and midrange chips that haven't been released yet. However, the leak doesn't include the Core i5-14600T as a successor to the Core i5-13600T. Whether that means the 14600T isn't planned is unclear. It does mention the rumored Intel Core 300, a dual P-core CPU, and its T-series counterpart.

Compared to Intel's 13th Gen T-series CPUs, 14th Gen models have higher clock speeds, usually 200 MHz higher, though the 14700T notably has a 300 MHz higher frequency than the 13700T while the 14400T is improved by just 100 MHz.

Although T-series chips are often pretty irrelevant for the vast majority of users, fans of small form-factor PCs may wish to take advantage of these lower TDP CPUs. While it's possible to simply take a higher TDP Intel CPU and just apply a lower TDP, there's no guarantee that the clock speeds will be particularly good. T-series chips are simply more reliable when it comes to Mini-ITX and other small form-factor builds.

    Intel's upcoming 14th Gen T-series chips have been leaked, and the frequencies look pretty good for their 35-watt power budget.

    Clocks only look good because you guys constantly fail to do any single core testing...
    The default power draw for the 14900k is 35W under single core so of course the t model will be able to do the same.

    I believe these are the final Intel desktop CPUs to support DDR4. So potentially worth snagging a used/refurbished OptiPlex with a 13900T/14900T several years from now, and reuse a DDR4 memory kit you have.

    I love the series T :) work like charm, don't heat the house and you can always put it somr more juice.
    Overclock the ram, minimal overclock on fsb and minimal incrase the maximum power. When you need to incrase the workflow.

    I'm not sure I'd be cheering yet with boost numbers of "Up to" and no base clocks. I've got an 8500T in a small form factor system and it's good for what it does, but in a multi-core workload the clockspeeds drop from "up to 3.5GHz" down to something more like 2.4~2.5GHz, which is closer to the base 2.1GHz for that chip.

    If you're playing a game while watching a video and with some social media open (or some other multi-tasking combination of multi-tasking), I expect the frequencies are gonna diverge from the standard version by a LOT.

    Now that's efficient!
    Typical, ignorant take we get from this author.

    Let's dig into what you get for 35 W, using the published specs for the i9-13900T. From https://ark.intel.com/content/www/us/en/ark/products/230498/intel-core-i9-13900t-processor-36m-cache-up-to-5-30-ghz.html:
    Performance-core Base Frequency: 1.10 GHz
    Efficient-core Base Frequency: 800 MHzSo, at 35 W, they're only guaranteeing your all-core workloads will get 1.1 + 0.8 GHz, for P + E cores. That's... not so efficient, in my opinion.

    Another thing about that 35 W is that it's the sustained power limit. Any other specs you see on this CPU pertain more to the turbo window:
    Processor Base Power: 35 W
    Maximum Turbo Power: 106 W
    106 W is not exactly small. If you have that in a mini PC, its fan would have to spin up like a hair drier to dissipate that much.

    I'd love to see some evidence of these claims, for Gen 12+. I've read the non-K models support B-clock OC, only. You can't get much more performance, that way.

    Also, from what I can tell, the T-series seems to be OEM-only. So, it also depends on how comfortable you are with either buying a prebuilt or buying a used CPU pulled from one.

    You can gain over stock 35w cpu more 20% boost making likely the counterpart with more watts :) I tell the people get one 13500t is cheap and can push the high graphics cards to the limit.

    Yes, your problem is that you always go by opinions and how things feel or seem or look like...
    For you to make sense here you need to give a comparison to something else so that you can compare the numbers, for all anybody knows these could be the best numbers ever.
    Here, let me give you an example.
    The 7950x uses 235W and has an all core clock of 5.3
    That means that it uses 6.7 times as much power and only gets ~5 times more clocks
    Samish, goes for the 13900k compared to the t model, 3.5 times more base power (125W ) for 2.7 times more clocks.

    You're talking about unrelated products and about scaling up, not scaling down.

    To examine the efficiency of these 35 W CPUs, they should probably be compared to the baseline, non-K versions. That's more likely what people will be deciding between - the base version or the T-version.

    Huh? No, i9-13900K used up to 283 W, stock.

    The big question: do these new CPUs have intel arc igpu on board? Because intel is very misleading by calling these CPUs 14th gen. They don't use the same 4nm lithography and they don't have the new GPU. Which makes raptor lake refresh a No Buy.

    And it is clear they are super power hungry and heat generators... AMD still remains the better choice (faster at much lower power requirements) I really thought Intel would finally catch-up after 4 years...meteor lake starts to get close but only for laptops.

    In 6 months alder lake cpu laptops will appear with thunderbolt 5 onboard. That might be the game changer .
