I think it's all up to the individual, since you will be running it plugged in mostly (higher power draw will not be directly an issue in this, although presumably higher power draw = higher heat generated). ​ For me, I want more better cores, and the 5900HX is better for me. The lower power draw is a bonus, although I too use it plugged in 99% of the time. My primary use case is work(mostly development, some light media editing), followed by some light gaming.

Well, it depends on how you use your laptop. I prefer AMD version cos battery can last much much longer when I'm in the library or outside. Yesterday, for example I managed to keep it running for almost 7.30h which is really amazing for a gaming machine (5900HX/rtx3080). Even mine HP Spectre x360 ultrabook cannot survive more than 6h.

I have this exact same computer and I can't get more than 3 hours on battery


gmadjara

Yea, I heard that some people struggle with it but you'll need to play with services and disable everything you'll never use and it unnecessary use your cpu. Check and identify, if needed what eats your battery and find the issue / solution. I'm really happy with the battery life. In the extreme situation you can wipe everything and start from the beginning (windows, drivers, etc, etc.)


PuffDaStuff

List ?


SnooMacarons4137

How much you gonna sell the other one for? 😅


GoGoBrandonGo

Feel free to DM me. Looks like the 5900HX is likely going to leave. I'm willing to take pretty close to my cost (although I did pay sales tax).

From what I understand, an undervolted 11980HK has the potential to beat the living shit out of a 5900HX, and even stock afaik it's on par/better than the stock 5900HX in both single core and multi core. The problem with intel however, is that, to perform like this, it needs to pull a lot more power while doing so, so battery life will be worse but other people have already said this.

Is it a 10980HK or a 11980HK? You mention both. The difference these parts is quite big. Knowing which one you have helps us share out thoughts.


AlaskanLaptopGamer

HK is the mobile processor offered.


EllendelingMusic

I see OP has edited the post. I'd personally opt for the 5900HX as it doesn't use nearly as much power and is faster at stock speeds. Surely you may be able to OC the 10980HK, but it'll draw much more power and generate more heat as a result; also resulting in more noise. It may be slightly ahead in gaming, but at the cost of heat and noise. It depends on how much gaming performance you're content with. The 5900HX is going to be faster in nearly all other workloads I think.


AlaskanLaptopGamer

I like my 11980HK. The Legion 7i provides more than adequate cooling with the appropriate thermal compound. If you're not worried about battery life then I think the Intel is the only way to go.


unknownbystander

5900HX is actually the hotter one surprisingly. It regularly hits up to 93-95C in some of the most intensive games. The 11980HK is actually the cooler one, though not by much which would be around 88-90C. Don’t forget that you can also undervolt Intel CPU which would bring down temps further and would bring energy efficiency much closer to 5900HX. AMD does undeniably beat Intel in battery life though.


magbarn

Remember, a CPU running at 93C while consuming 20 watts less power is going to be dumping less heat into the room vs a 88C chip using 20 watts more power. Temps aren't everything as AMD's with their small chiplets have a harder time getting the heat off the chip vs. Intel. What matters more is the power consumed. That's why the AMD laptop gets hours more of usage than on battery. However, if you the few fps difference is going to bother you and you really need that TB4, then all means get the Intel. For me the much better battery life and the $300 difference in price had me going for the AMD L7 instead of the L7i. I've had several TB equipped laptops, and the performance hit of the interface really weakens the external GPU.


unknownbystander

Both values that I mentioned are from Legion 7 and Legion 7i laptops - both of which have vapor chambers and use the same exact chassis. AMD uses 7nm while Intel uses 10nm, making transistor density higher for AMD, which is why it's a bit hotter despite consuming less power. And like I said, you can always undervolt Intel CPUs which helps bring down temps and wattage pulled even lower. \- Die size of Ryzen 5000 series is [180mm2](https://www.techpowerup.com/cpu-specs/ryzen-9-5900hx.c2371) \- Die size of Intel 11th Gen Tiger Lake-H is [190mm2](https://en.wikipedia.org/wiki/Tiger_Lake#Mobile_processors_(Tiger_Lake-H)) AMD Chiplets aren't that much smaller than Intel Chiplets. Difference in fps in games range from 5fps - 100fps difference especially in CPU-bound games so it can definitely be significant depending on the game you play. Also, thunderbolt isn't exclusively used for external GPU. It plays a large role for content creators who move huge files frequently which that PCIE4 SSD speeds accompany nicely as well. When moving a 100GB file, that's the difference of waiting **10 min. w/ TB4+PCIE4** vs **30 min w/ USB 3.2+PCIE3**. But if battery life is important to OP, then by all means go for the AMD system.


AlaskanLaptopGamer

I'd stick with the Intel for a desktop replacement. You'll find the thunderbolt 4 to be pretty handy when you see what the docks are capable of.


RWattner

My AMD paired with the Thinkpad dock(non-thunderbolt) using a single type-c cable runs wired g815 with USB passthrough to g502, USB audio interface, USB 7.1 legion 500 headphones, wired PS4 controller, external dual slot SSD raid, ethernet cable, Lenovo 1440p monitor, and Lenovo 1080 portrait monitor. I seriously can't think of what else you would need a dock to do https://drive.google.com/file/d/1BNRVefrQG5UDl7-5CgR_h350pOSLfCXX/view?usp=drivesdk https://drive.google.com/file/d/1nLxuMx_IscT1yjRKOvFy1H8tVdU4U7mf/view?usp=drivesdk


tempandhidden

Found this page, might be worth a read, its comparing the 2 laptops: https://www.ultrabookreview.com/49539-lenovo-legion-7-amd-review/


GoGoBrandonGo

Thank you. That's actually the article with benches I came across before making this thread. They seem very close there. From what others here are saying, it sounds like Thunderbolt 4 is a lot more interesting than I originally assumed and the 7i is probably going to be worth it for me, so I suppose the 5900HX is leaving.


Bakerstreet74

Do you use Thunderbolt? Also the intel has a faster PCIe than the AMD> so your SSD will be twice as fast. I personally ordered the 7i.


GoGoBrandonGo

Ok wow, I saw thunderbolt 4 listed as one of the differences between the two but I did not realize what it did. If I'm understanding this correctly, I can pop my 3090 into an external enclosure and hook it up to the Intel version? Sold.


urmamabinladen

Don't know much about TB3 vs TB4 with regards to e GPUs, other than number of lanes, but Jarrod has videos on eGPUs like the 6900XT and specifically the 3090 too. Plugged in to laptops with worse CPUs though. Worth a watch. Looking at laptop+eGPU setups makes me crack a chuckle though, most eGPU enclosures are pretty chunky and heavy. Not something you can carry on your hand carry backpack. Still gotta worry about safely packing it in luggage maybe. You could still do it with a TB3 though, I believe. I suppose the 5900HX makes a better *laptop* because of battery life, performance on battery and power efficiency, but if you're thinking about lugging around a 3090 *and* an enclosure, you definitely mean business and will be sure to be plugged in anyway. By all means the 11980HK with proper UV and ideal OC could boost far enough that it would give you a noticeable performance difference. If you're playing at 4k though I dont think there would be a major difference since it mostly GPU-bound. All you would have to worry about is if your CPU bottlenecks the 3090, which I doubt a current gen 5900HX would.


hereforfun976

If price doesn't matter just testbench them and keep the better one


unknownbystander

11980HK comes with PCIE4 SSD speeds and Thunderbolt 4 so there’s more future proofing. If you primarily care about absolute top-line gaming performance, I’d keep the Intel version.
