Yes. Of course it will boost higher (up to 65 W I believe) but will settle at 45W sustained power. It does have a cTDP of up to 54W though so it can use more if the OEM configures it as such. By contrast the 10980HK has a 45 W TDP and can use up to 135 W during boost and OEMs can configure it with a cTDP up to 65W.
That is the rub. It’s very difficult to compare laptops that have the same cpu and dGPU because the laptops can differ drastically in configured TDP, cooling, RAM specs and settings, and even have certain reductions in dGPU capability that aren’t advertised. That’s why you have to wait for benchmarks and tests in the wild.

That's why I said default is not relevant. The manufacturer can set it at levels way different than what the spec sheet says. The H version runs at 60W+ in some laptops.
That's not a bad thing, as it gives them design flexibility. Rather than making a design and making everything else around it, you can adjust the TDP levels to what is needed.

Intel have published an interesting paper about Focused Value Prediction and the implications it has for future improvements to CPU architecture:
Just some snippets here that I personally found interesting:
"Value Prediction was proposed to speculatively break true data dependencies, thereby allowing Out of Order (OOO) processors to achieve higher instruction level parallelism (ILP) and gain performance. State-of-the-art value predictors try to maximize the number of instructions that can be value predicted, with the belief that a higher coverage will unlock more ILP and increase performance."
"FVP significantly reduces the area, power and design complexity of implementing value prediction, while still delivering large performance gains. Detailed simulation results on 60 diverse, single threaded workloads, show that we value predict about 25% of all load instructions and deliver 3.3% performance gain over a baseline similar to the Intel Skylake processor. This performance grows substantially to 8.6% when we simulate a futuristic processor that has double the OOO resources of Skylake. "

OK, this is funny. New rumor saying that the Rocket Lake i7 will be 8C12T. It's probably a typo but it is possible. Intel with Comet Lake added the ability to turn off HT on a per core basis.
The i9 would be 8C16T and i5 would be 6C12T.

Even funnier will be CML i9 vs RKL i9 in MT loads, although if that segmentation is true then it may actually be good news for RKL performance.

Pretty sure it'll fall behind. I'm thinking Intel is just going for the highest ST possible, so that they 'may' jump ahead of Zen3.
Intel is not in a position for a segmentation like 8/12 because they need everything they have, but this could be a typo.

Let's face it, Comet Lake-S ain't all that. I mean sure it works, it's . . . quite a bit faster than Kabylake and Skylake in MT just from the core count, but Intel should be able to at least match it in MT with 8c Rocket Lake. If they can at least keep the heat flux down to equal the 10900k it won't be a terrible chip. It just will have no real value outside of premium desktop and gaming. That kind of MT performance in 2021 is just not that special anymore.

The gap between the two in MT is going to be less than 10%. It probably makes a lot of sense to go for the i7 part if you are going to get gaming system.

Rocket Lake S 6C12T model with 256KB L2. Dunno if this means there will be 'Rocket Lake' with Skylake cores as well or there will be models with the L2 cache cut.

Can you elaborate? I thought your sentence " It just will have no real value outside of premium desktop and gaming " was the point you were making.

Rocket Lake-S will be Intel's non-HEDT desktop flagship until they are able to launch Alder Lake-S. It is designed for all computing tasks. Not just gaming. It is also designed to meet the needs of the entire market - DiY, various different OEMs, you name it.
If it fails in a particular market, it fails due to Intel's incompetence. Not due to it being a chip "designed for gaming". As recently as 2018, Intel had the fastest non-HEDT desktop chip on the market in the 9900k. If you wanted to encode media, render, or game, it was faster than the 2700x or anything else in the desktop market. Rocket Lake-S is tasked with nothing less than occupying the same space on the market. It will fail.

I still cannot wrap my head around big.Little for a desktop cpu, well, certainly not for a high performance cpu.

We'll see. Having 8c Golden Cove won't be a bad thing, and with Tremont looking kinda okay actually, Gracemont could be pretty good. It will be a change for sure, though, and it may not stack up all that well against chips coming out this year, much less those currently scheduled for 2021 . . .
Gaming probably drove the core count decision. Well, that and the power draw.
It sounds like there's going to be Comet Lake rebrands as well so you shouldn't be surprised the bulk of the OEM desktop market use that instead.

It's weird Alderlake is an 8+8 configuration. That's actually the same amount of ring stops as 10 core Cometlake, possibly meaning they see ringbus as the limiter to scaling above that, and mesh doesn't work well for client.
Alderlake update:
For Sapphire Rapids
It's interesting it does not talk about AVX-512 for Alder Lake. So its very likely both Golden Cove and Gracemont supports AVX-2 but not AVX-512. AVX-512 continues to be an instruction for HPC.

The target for Cannon/Ice/Tiger do mention AVX-512. As Phoronix mentions it's more likely that it's the LCD between it and Gracemont than AVX-512 being removed because Small doesn't support it. Gracemont is not mentioned at all yet.

I think it was down to power draw and die size. Transistor count per core is up with both Sunny and Willow Cove. Moving to the uh . . . whatever it is they're really using in Rocket Lake-S left them with less die real estate for cores. There is likely no realistic way for them to go beyond 8c on 14nm with their newer core designs. Gaming performance is just an excuse. They're hemmed in by process.
edit: oh also I agree that Golden Cove probably has AVX512 supported in silicon. If Gracemont doesn't, then yeah they'll just have to disable AVX512 all around. So ironically, Cannonlake; IceLake; and Tigerlake have AVX512 support but Alder Lake won't.
An interesting observation, though mesh can work well for client at higher mesh speeds and with cache configurations aimed at client workloads (read: not what you find on Skylake-SP and its descendants).
