Intel Core i9-13900HX 8P+16E Mobile Processor Beats Desktop i9-12900K and i7-13700K
Intel's "Raptor Lake" microarchitecture will go mobile this 2023 International CES, with the company planning to substantially expand its 13th Gen Core processor family for notebooks, ultraportables, convertibles, tablets, and pretty much any PC form-factor that you can carry around. The high-end enthusiast mobile parts see processors in the 55 W to 65 W (or higher) TDP range, and with the same 8P+16E core-configuration as the desktop Core i9-13900K, including support for enthusiast features such as overclocking.
The leaky taps on social media are ready with some of the first benchmarks of Intel's new mobile flagship, the Core i9-13900HX. The Geekbench score of the chip puts it faster than the desktop Core i7-13700K (8P+8E) and Core i9-12900K "Alder Lake" (8P+8E), which enjoy power limits of up to 251 W, base power of 125 W, and a much more relaxed power-management scheme compared to a mobile chip like the i9-13900HX. The processor scores 2039 points in the single-threaded test, and 20493 points in the multi-threaded one, which puts it ahead of the desktop i7-13700K (which in turn is faster than the i9-12900K). Geekbench detects the processor to feature a maximum P-core boost frequency of 5.40 GHz, which isn't too far from the 5.60 GHz of the 65 W desktop i9-13900 (non-K). CES promises to be action-packed with Intel expected to announce dozens of 13th Gen Core "Raptor Lake" mobile processor SKUs, and NVIDIA expected to announce the first mobile variants of its GeForce RTX 40-series "Ada" GPUs.

People seem to keep forgetting this.
My HP EliteBook can't keep an 18W CPU from throttling. Imagine what 65W+ would do..
Laptops are limited by cooling, so the cTDP is kind of pointless to get concerned over. If the dGPU isn't demanding the lion's share of the cooling, the CPU can use the additional headroom. Will it be quiet, cool, or efficient? Of course not -but the people who buy the big chungus laptops with CPUs like this don't really care about svelte portability, efficiency, or discretion...

While running under heavy load high wattage laptop CPUs will gradually reduce frequency.
Hell, the desktop world itself has fully adopted this type of operation, look no further than Ryzen 7000X series.
And I can't even begin to imagine the solution that will be used let alone actual Temps. I have an i7-13700K and a 360mm AIO with Noctua A12x25 (2000 rpm), three front mounted 140mm fans and one 140mm rear. My Temps max out around 80 for real world heavy loads. And that is with all that cooling in a mid tower (plus GPU heat).
Cramming this 13900HX into a laptop and a GPU on top of that... Those temps are going to be toasty at best, maxed out most likely.
10 minutes battery life at full tilt if it didn't throttle after 2 minutes.
Any way who gives a stuff with Phoenix APU's on the horizon and already effectively outed by Lenovo. Zen 4 + RDNA3 goodness.

Depending on how narrow Intel makes the bin, a die operating at low voltage could achieve around 105W. In any case, models equipped with the 12900HK and 12900HX can still dissipate around 90 W of heat in a stable manner. Although, their weight reaches 3.0 kg (6.6 lbs).

So Intel may actually be really, really close this time, if not better at ligher loads. Damn nice
It has 8 more e cores, so it is going to be faster in multicore workloads, that is just plain obvious !
How does it fair with gaming and single core workloads? Now that would be more interesting!
And of course battery life whilst gaming and doing mutlicore workloads?
I guess its good they cram more e cores in, I suppose?
