Intel Core i9-13900HX 8P+16E Mobile Processor Beats Desktop i9-12900K and i7-13700K

[btarunr]

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.

I wonder what kind of "innovative cooling solutions" this will require.

in the 55 W to 65 W (or higher) TDP range

The cake is......

Direct die can do a lot more than desktop cooling over an IHS can in cooling efficiency.
People seem to keep forgetting this.

nono, its for Each core

That is true; but 65W (or higher) is still a lot of heat that needs to be cooled in a laptop! That requires a beefy heatsink.
My HP EliteBook can't keep an 18W CPU from throttling. Imagine what 65W+ would do..

 

[Chrispy_]

I'll assume these draw ~130W or so for PL2.

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...

 

[yeeeeman]

this can be obtained only for short burst workload. any other longer workload will either require DTR cooling or will drop to half of this.

 

[P4-630]

Now if they only make these CPU's fit for a desktop socket..........

 

[tommesfps]

One major problem is that nearly all laptops with discrete gpus have their heat pipes streched all over both cpu and gpu at the same time. You have to look at a two or tree heatpipe cooler and a combined tdp of two chips. Imagine your 200Watt TDP rated CPU cooler had to cool your 300Watt GPU at the same time.

Current gaming laptops already have significant issue with heat buildup and throttling

Frequency reduction from top available frequency isn't a fault, its a byproduct.
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.

Agreed! Let me put this in a mini itx box with a 3 slot gpu.

Repaste it with something of quality (AC MX-4 for example) and you'll be fine I have a Dell Vostro with really shitty cooling and a 5825U, which is set by default to 25W and it throttled like crazy. I repasted it and now I can run 32W TDP at all times without reaching the 95°C throttle mark

If you thought gaming laptops were loud before, anything with this in its going to need hearing protection.

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.

 

[Minus Infinity]

How do you spell T H R O T T L E.

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.

65 watt TDP, 150-170 watt power limit for turbo? 45 watt Alder Lake SKUs boosted up to 115 watts. Desktop 65W i9s boosted up to 202 watts. I would assume something between these two for mobile 65W RL. So it's going to be slower than desktop 7950X at similar power levels, it seems. Yet another great "mobile" CPU by Intel.

In this site's review, stock 13700K scored 30781 on Cinebench R23 MT. Performance of Power-limited 13900K was reported the following values:

32737 @ 140 W [PCWorld]
29334 @ 105 W [PCWorld]
31305 @ 125 W [AnandTech, DDR5-6000]
30421 @ 125 W [me, DDR5-4800]
31672 @ 125 W [me, DDR5-4800, Vcore offset -100mV]

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).

As a comparison to AMD's 7950X:
34300 @105 W TDP (142W PPT) [PCWorld]
28655 @65 W TDP (88W PPT) [PCWorld]
28515 @65 W TDP (88W PPT) [PCGamer]
35423 @105W TDP (142W PPT) [KitGuru]
29473 @65W TDP (88W PPT) [KitGuru]
So Intel may actually be really, really close this time, if not better at ligher loads. Damn nice

 

[GURU7OF9]

I dont understand what all the fuss is about with the new 13800HX faster than 12900k and 13700k.
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?
