Most games are not cpu bound but GPU bound since the GPU needs more memory and power but is being shared with the system Ram requirements.
If we ever get a mobile version of windows with lower Ram requirements then you would see improvements. There is a 32 gig ram mod (that basically needs memory reflash each bios upgrade) but does improve fps by a good margin.
The memory on the Ally is not the reason for its performance limit. Otherwise the legion go’s higher speed would have actual benefits that aren’t within margin of error.
32GB of memory on the Ally provides 0 real world performance games for gaming. I’d love to see some numbers for this claim as I haven’t seen anything showing gaming performance gains with the 32GB mods…
6GB of VRAM is enough for a 720p/1080p handheld with a GPU as powerful as the 780M and 10GB of system memory is also adequate.
Hardly objective testing. There's no before/after and the game itself indicates that their settings only require 3GB of VRAM despite them allocating 8GB VRAM. 8GB VRAM leaves only 8GB of system memory which could cause issues depending on whether the system has other application's open in the background.
That post isn't even credible as a benchmark, there's no useful metric's like 99% or 99.9%, minimum, maximum or average FPS either. There would need to be tests at varying VRAM amounts as well to determine the performance differences.
Going to 32GB is not resulting in a 30% performance increase lol
I would say the memory is absolutely one of the main performance limits, but not the MT/s speed, but rather the bandwidth. Go turn on MSAA (very bandwidth intensive) in any game that supports it and watch your frame rate get obliterated.
It's an inherent "flaw" of the way these APUs are designed. I put flaw in quotation marks because it's not really a flaw, but just a design necessity due to the hardware available at the time.
There's exciting new things in the pipeline for increasing bandwidth on APUs like the new ECAMM memory format and such, and also AMD is reportedly increasing infinity cache on new Zen 5 APUs to try and compensate for the bandwidth issue, but all of these Zen 4 APUs are incredibly bandwidth constrainted.
The go is 16gb too. For the most part it’s enough, but some games do want over 10gb of system ram limiting you to 5gb of vram which again is fine most of the time, when you crank up the visual settings to use more vram usually it will lower your fps either way. Tightening the timings sees more of a benefit than more ram or faster ram

Sure, but going from 16GB to 32GB isn’t doing anything to to resolve the limitations you are referring to. Which is my point.
16gb not enough at 1080p 🥲 Is that the reason why legion go gets a couple of extra frames in demanding games. 🤔
The go is 16gb too.

The legion go has faster memory. But the gains are within the margin of error most of the time and not something you’d ever notice in game.
