he 13700HX had a much wider range of variance than the 7840HS, which means you can get a laptop that's anywhere from 25% slower than default spec to 5% faster.
OK but does that mean variance per brand/model or per serial unit?
![Confused :confused: :confused:](https://tpucdn.com/forums/data/assets/smilies/confused-v1.gif)
If the former its not much of a worry considering a user has already been kind enough to post
aggregate benchmarks for different brands
For the one im interested currently because of my budget (Omen 16) The 13700HX scores higher in both multi and single core tests
That means it's much harder to cool. Not only is the performance highly dependent on the OEM implementing a good cooling solution, it will be a pain during the summer months.
This is my main worry that would make me consider AMD, if the i7 13700HX throttles to the point its gaming performance falls below 7840HS
You are talking a 3 hour 41 minute battery life vs a 7 hour battery life while simply surfing the web. A laptop with that low a battery life almost defeats the purpose, especially as the battery will more quickly degrade as it's during through cycles more quickly.
This is really a non issue for me, since as long as I can remember I have always used Laptops plugged to the wall. Whenever im using my current laptop im indoors 90% of time at home. Dont really see the point of wasting charge cycles if im at home only to plug in again to charge even if the CPU is super efficient seems like a waste to run on battery at home barring some exceptions for convenience
Specially not for gaming I don't see the point of running on Battery
Seldom I would use on battery for some light tasks, not that its a deal breaker but why do you think battery life would be so poor browsing the web? From what I understand Windows and modern CPUs have very good power management, if you arent doing anything pushing hard on the CPU its power consumption will be relatively low and Power Saver mode also helps for such cases.
In any case the 13700HX base clock TDP is 55W not much more than 7840HS 35-54W TDP. For seldom on Battery use i can always make a custom power plan that disables turbo boosting. The performance at base clocks will be overkill for anything I do on battery anyways, and multiple times greater than my current laptop
Even the most demanding consumer applications (like games) do not saturate 6 cores, let alone 8 or more. You really only want more than 8 cores if you are a professional doing something like video encoding as part of their job.
I don't expect to use more than 8 cores, I already said for my use cases both CPUs are great and more than enough HOWEVER considering they are going for the
same price might as well get the extra E cores.
Let's assume for a second that your hypothetical scenario comes to pass and windows starts loading up more than 8 cores with processors or regular apps start using that many cores. Would you really want a 171w jet engine running all the time when you are using your laptop with maybe a 20 minute off the charger battery life?
Having E cores offloading background tasks, means the 8P cores will
always be 100% available when needed for gaming or any other heavy task
That's the immediate benefit i see. Im not saying all cores will be taxed 100%, im only pointing out the value of E cores offloading background tasks leaving P cores resource availability to 100%. Also great for multitasking
For my use case (plugged to the wall) and budget, why would i not take 8 free E cores even if their net benefit today is only 1% its still free cores for my money.
the laptops usefulness primarily being it not having to be plugged in.
Eh... I disagree with that, specially for Gaming laptops they are meant to be plugged in and its not like its some hassle to plug the laptop in the place where it will be used 90% of the time
The benefit for a laptop from my experience is portability. I can take it to different rooms in the house, or to a friends/family house, school/work if needed.
All places where i would use the wall outlet anyways.
The battery is very convenient for light tasks (web browsing, office) if you're moving it around a lot but for my day to day use case its just sitting in the same desk/table.
The higher the power consumption the more bulky the laptop must be which is counter-intuitive to being portable.
In this case im looking at the exact same brand and model that offers different CPU configuration so this would not be a differentiator
The main reason i made this thread is because of it. I found this model that met my budget and perfomance expectations and offered the two CPU configurations
But, at least for the Legion, performance on the 13700HX is a known factor already, so that's a non-issue.
Do you happen to know anything about Omen 16?
Someone already posted geekbench scores do those count?
The power draw question is up to you, really. The battery life and longevity arguments are kind of moot considering that you are overwhelmingly planning to be plugged in for max performance, and neither are physically very portable designs at all.
Pretty much
The cooling argument is still relevant, it just depends on how important it is to you.
Its very important to me if it means it will throttle gaming performance below the 7840HS, main reason I made this thread was because of that worry actually
Best not to speculate on how Windows will use those cores in the future, in either case. On many occasions Windows has been proven to be no ally to either AMD or Intel scheduling.
More than anything i just meant having additional cores means the P core resource availability will always be 100% thats true today and will be true in 5 years.
Its a nice to have but not game changer kinda thing
In the laptops it's better to think of them not as E-cores but just "more cores".
Agree, its just easier for me to talk and differentiate between the two since its so short to just say E or P
been looking at laptops as well, but the pricing is pretty ludicrous. Seen a base 7040 and it was about $2k CAD............
This so much, AMD/OEMs marketing is so bad
AMD has such good CPUs marketed terribly to the wrong segments, completely missed opportunity
One of Phoenix main differentiators is its superb iGPU performance, its such a waste to not offer a entry level option without discrete graphics for say $800. I was initially on the market for something in the $800 price range preferably Phoenix but after I realized my only option in that sector was intel (i7 13700H) I decided to invest a bit more on a discrete GPU model (considering Intels iGPU is very underwhelming). So now my only choice is to buy a laptop with a discrete GPU
I dont know what AMD future plans are but 780M is the greatest dumbest thing they made. If they were planning to just offer Phoenix with discrete graphics they should have just made the GPU with 2 CUs instead of 12CUs and save the die space to make manufacturing cheaper and offer a cheaper alternative to Intel
Right now Phoenix lost its biggest advantage imo because of AMD/OEMs terrible market read
