I am not sure what the hell you are talking about the GPU of the Ryzen 5 5500U. MX450 is nearly 40% more powerful than the Vega 7 in this 5500U, running in dual channel with the highest spaced 4266 MHz LPDDR4X Ram.
Now why you need a different Ram setup? LPDDR memory configuration are always done in Dual channel and this is as well. a 4266 MHz dual channel LPDDR4X will always perform better than a normal DDR4 3200 MHz Ram in dual channel. From where did you get the idea that this one not running in dual channel? The only complain is that the Ram is limited to 8GB.
Technically, 4266mhz DDR4X dual-channel only has 32bit bandwidth vs normal DDR4 dual channel which has 64bit. This is why we still see 3200mhz DDR4 dual channel as a top tier memory config vs seeing DDR4X (especially in gaming laptops).. DDR4X is much more energy efficient. But in the case of Ryzen + MX series GPUs I agree with you, we likely wouldn't ever see any performance benefits of a 64bit memory setup as we're not memory bus bottlenecking anything in a ULV based machine.
Not looking to argue with you or protecting any other members, you can continue "running the streets" - the majority of comments are completely inaccurate around here.

Don't make up things and benchmarks. MX450 is over 30% faster than even Intel Iris Xe 96 EU Graphics in Core i7, which in turns, almost 20% faster than Vega 7 in 5500U. These type posts doesn't show your tech knowledge but highlights the lack of it.
And regarding battery life complain, have you heard the term Optimus?
You have to keep in mind this particular MX450 is 12-15 watts TGP (from HWInfo's readings) so it's the lowest power variant of the MX450.. Full power MX450 would be 25w. The performance uplift between Vega7 and M450 isn't as exaggerated in this particular machine but it's still a nice-to-have feature at the cost of having an inline GPU robbing battery life when idle since Optimus isn't perfect.
I'm only bringing this up for any folks who think they are getting a full power MX450 when they definitely will not be.

Let me clarify couple of things and your misconceptions: -
Regarding your MX450 TGP, there are plenty of tests and even the 12W version found in the ZenBook 14 or in HP Envy 13 (non-x360), outperforms Intel Iris Xe 96 EU version by more than 30%, although in some artificial benchmarks, Iris Xe scores higher. In any games or GPU accelerated workloads, MX450 always performs minimum 10% to up to 30% better. Now Vega 7 in this Processor is itself around 10% to 20% slower than Iris Xe in the first place. Proof: Check the below reviews where the Zenbook 14 Intel version with i7-1165G7 and MX450 12W has been tested against Iris Xe. https://www.notebookcheck.net/Asu...058.0.html
LPDDR4: I am not sur from where you got that 4266 MHz dual channel only has 32 bit bandwidth because that is completely wrong. Unlike DDR4 memory which can only be configured in 2x32 bit mode to be operated in Dual Channel Mode, LPDDR4/X memory can be configured in 2x32 bit or 4x16 bit. In fact, there are Tiger Lake Laptops where the LPDDR4X memory run in Quad channel 4x16 bit. I think you probably goy confused with the 16 bit one, thinking dual channel means 2x16 bit. No, it can be 2x32 bit as well. That is the common feature of any LPDDR memory, whether 1, 2 or 3.
Anyway, technical discussion aside, I have personally benchmarked IdeaPad 5 14 and IdeaPad Slim 7, configured with Ryzen 7 4700U with same TDP, with the first one running 16GB DDR4 3200 whereas the later running 16GB LPDDR4X 4266MHz Ram and Slim 7 always performs better in every gaming benchmarks due to having a faster Ram.
I have an older zenbook UX305. love it and my mom is looking for a new laptop and prefers lighter laptops. so this might be a good fit
I actually think this is a really good deal, the 8gb non-upgradeable ram is the only reason I haven't pulled the trigger. Depending on what your mom uses it for, I doubt she would ever need more than 8gb. If it had 16 or the ability to upgrade, I would say this is an amazing deal.
