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/u...3900t-processor-36m-cache-up-to-5-30-ghz.html:

Performance-core Base Frequency: 1.10 GHz
Efficient-core Base Frequency: 800 MHz
​

So, 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.

Here, let me give you an example.

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 .

Having different microarchitectures branded under the same generation is not new territory, for Intel. For instance, Gen 10 had Comet Lake (a Skylake-derivative) on the desktop, made on 14 nm, but Ice Lake - a new microarchitecture and made on 10 nm - for laptops. ...except high-end mobile, which was Whiskey Lake - another Skylake-derived 14 nm processor! We can also talk about 11th Gen, which featured the 14 nm Rocket Lake for desktops and 10 nm (SuperFin) Tiger Lake on laptops.

In this gen, Intel seems to have sidestepped such issues by introducing the Core Ultra branding, for laptops (i.e. Meteor Lake).

These specific T-series CPUs are just Raptor Lake Refresh, which makes it very consistent with their use of 14th Gen branding.

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

I guess you mean Arrow Lake? From what I've seen Arrow Lake-H aren't supposed to launch until the end of next year.
