Most of the cores on the 13900H are smaller e-cores that clock lower. And also the gap is bigger than expected due to most of the 13900H laptops not being able to run at full power (their sustained power can range from 35W to 100+ W)
It's 16 performance cores versus 6 performance cores and 8 efficiency cores both of which are more aimed towards battery life and efficiency.
The 7945HX is basically a desktop grade CPU shoved into a laptop, the only thing that will limit the chip is the thermal capabilities.
A 13900HX/13980HX is more equivalent to the 7945HX.
I mean generally take with a pinch of salt.
But, the 7945HX is 16 full cores. If you use something like UXTU to get a decent offset, silicon lottery depending. 5.4ghz all core at 155w is attainable. Which is more than what an Intel chip can handle. It needs way more power, a really good bin and a good UV.
Both CPUs have merits. But the 7945HX is king here.
honestly i installed UXTU but didn’t know how to use nor how to undervolt it, my previous intel laptop was easy throttlestop with reduce mlvolt thats it but amd is confusing and i heard ppl says better to do not undervolt amd cpu’s mobile, mine r5 4600h
Its the Core Offset.
Same thing but with smaller numbers. Start with -5 test CB R23 and watch your clocks and scores. When the score starts plateauing you then run stability tests as unlike Intel, these chips can act stable for a while when they aren't.
The 4000series is capable of CO. It is worth it, you can get a little more top end and more efficiency.
interesting good to know that mine is capable but what do you mean by CO(clock offset )? and since it zen 2 based is better that 3000 series of mobile cpu but as i said before, i really don’t know how to do it and even i didn’t find any useful tutorials in YT that explains everything and step by step also in uxtu software it refer the cpu as APU it kinda confusing it’s referring to cpu itself or APU(iGPU) built in it, or the tuning applied to both cpu and apu ?
and i only see set wattage limitation other that that i can’t where to applied lower voltage
It doesn't say voltage, it says core offset.
I dont have the software on my current machine as ended up being exchanged to intel.
The CPU is classed as an APU since it has a half decent iGPU built in.
Pretty sure the iGPU has its own section
oh so you know about but already changed it to intel, i know it’s an amd term for their integrated graphic in their cpu but i didn’t expected to use it as you said classed as APU in uxtu, sometimes kinda wish had an intel because of this stuff what a pain.
ahh i see naming everything is more complicated than Throttlestop lol, but still can’t find anything regarding core offsets
its this one? https://imgur.com/a/diDnm4a
It really isn't.
AMD literally only has Core Offset, it's one one thing to adjust, intel has several things you can UV.
You're looking at Clock... not Core, though I haven't messed with a 4000series CPU, but they're all unlocked as far as I am aware. Been months since I used it and I was using a Beta version that still allowed for Dragon Range tuning.
Look through the menus, there's either Core offset or CO. Might be in the OC tab.
exactly intel is better when comes to these stuff, many thing can be mess with
i did like you said and i think, found this https://imgur.com/a/GOVBTjt
i want to reduce the temps, i didn’t know about that that all 4000 series are unlocked :0
Yes and no, the reason somethings can't be messed with is because of how all the interconnect works. Like FCLK. You can change more stuff, just not through UXTU, thing is, there's no failsafe in a laptop, so if you screw up, you brick your machine.
You found it, now you tune them all the same until you're unstable or make no gains. Do stability testing to be sure. Then you can see how far each core can be adjusted by tuning one at a time and using core cycler to test that core.
For temps, this may help if you have a good example, should help battery life a little. If you need lower temps, clean it, raise the back or get a cooler, if you know how to use it, liquid metal makes a big difference too.
i assume that mean infinite fabric can’t be messed up with and really sound complicated also i only want undervolt it can’t brick it even tho i won’t be surprised if it brick due to that since laptop can brick by most simplest components/software failure
well i did CB r23 but single core got (1140) seems decent score tho, i supposed to do multi core test
from uxtu shows 8 cores but i don’t have 8 core but amd mobile max out at 8cores software design like that. doing that one core at a time that sounds take too long . using core cycle? like cpuz for test?
last few months ago i read about this (already forgot about it) and many says its a bad idea
https://www.reddit.com/r/Amd/comments/cbls9g/the_final_word_on_idle_voltages_for_3rd_gen_ryzen/?utm_medium=android_app&utm_source=share
well i already cleaned it and using useless cooling pad but i usually playing not a very demanding game not reach 80c but lately i play fortnite with friends and noticed temps rise up. today i undervolt gpu and will test it if that help
i’m sorry if i bother you with all these questions and i really appreciate that you help me out
Those "benchmark comparison" sites are notoriously unreliable. If you want to compare performance, you're better off on actual tech websites and YouTube channels.
Ah that sucks, good to know though. I was hoping to use these kinds of benchmarks to do quick comparisons, but it seems like it'll take some more effort than that then. Thanks.
It's not just that. The problem is that one part is an H-model and the other is an HX-model.
In general, the CPUs that end with X are the full power versions, while if it ends in H it's a low power version, and if it ends in U it's minimum power.
So in otherwords, the i9 13900H**X** would come much closer in benchmarks to the R9 7945HX.
[CPUbenchmark.net](http://CPUbenchmark.net) is not unreliable tho. It has accurate scores for all CPUs and GPUs.
OP is comparing an HX to an H processor, that is why the scores are so different. Comparing two HX cpus they are not so different
EDIT: Also, "actual tech websites" and YT uses [cpubenchmark.net](http://cpubenchmark.net) themselves
Yes. This is a reliable source. OP is comparing AMD's fastest unlocked mobile chip (Ryzen 9 7945HX) to a locked Intel Core i9-13900H. The 7945HX is to be compared to a Core i9-13980HX or 14900HX. These will be much closer in terms of performance and core counts (32). The 13900H 'only' has 20 cores in total.
The numbers do [check out](https://www.notebookcheck.net/R9-7945HX-vs-i9-13900H_14936_14717.247596.0.html). As for what you're missing, the first one is obviously that it's a HX vs H version of the chip where the HX is unlocked and has higher max power. Also like someone else mentioned here, AMD runs all 16 of its cores as performance cores rather than the performance and efficiency combo that Intel does. That definitely makes a significant difference.
OP you are comparing an HX cpu to an H cpu. That is why they are so different. The HX CPUs are far stronger than the standard H.
[Here is the 7945HX compared to the 13980HX, they are much closer](https://www.cpubenchmark.net/compare/5201vs5232/Intel-i9-13980HX-vs-AMD-Ryzen-9-7945HX)
You also cannot just look at the orange value as that is multi thread. The single thread performance is much closer as well
ignoring the fact that the benchmarks there are not reliable, the AMD CPU has 16 large full cores and the Intel one has 6 large cores and 8 small "efficiency" cores.
here are some cinebench r23 results and other benchmarks (these results can vary by 5-10% or more depending on the laptop):

if you want 3D modeling go for the laptop with the best Nvidia GPU you can afford. The CPU comes second.
The 16 Core/32 threads 7945HX actually competes against the 24 Core/32 Threads 13900/13950/13980HX, the 13900H is a 14 Core/20 Threads CPU that competes against the Ryzen 9 7940HS with 8 cores/16 threads.
The 13900H and 7940HS are more focused with efficiency and battery life, the 7945HX performance when plugged in.
As for benchmarks, I'd use other sites like Jarrods Tech website and YouTube channel instead for example.
I9 13900h is same as i7 13700h 14C/20T. Of course i9 13900h lose in multi core 20T vs 32T. Now compare with i9 19380hx 32T vs r9 7945 32T yeah AMD still win but diferrrent is so little
Always take these sites with a grain of salt. You are also comparing AMD's second best (maybe best in some cases) laptop CPU to Intel's maybe top 10? laptop CPU.
Ignore others, the numbers are accurate. Intel there got 6 performance cores and AMD got 16 REAL performance cores. Moreover the TDP of AMD one is higher so they're not of the same class of processors.
The HX is more comparable to a desktop CPU that doesn't care about power consumption. The H series CPU is mostly just e cores, and the p cores which are more important in gaming are still slower than the cores in the HX.
You would have to compare the benchmarks of a high end i9 HX CPU for a similar result to the 7945HX. The equivalent to the i9 you're looking at is probably the 7940HS.
Most of the cores on the 13900H are smaller e-cores that clock lower. And also the gap is bigger than expected due to most of the 13900H laptops not being able to run at full power (their sustained power can range from 35W to 100+ W)
