Intel 13500HX: 2x8GB (Single Rank) vs 2x16GB (Dual Rank)
2Pretty niche benchmark runs. All benchmarks done on the same laptop, Acer Predator Helios Neo 16, DDR5 RAM is clocked at 4800mhz.
Marvel's Spider-Man Remastered benefited the most, probably attributed to the increase in capacity, at 16GB (2x8GB) the game stutters every few seconds, at 32GB (2x16GB) the stutters are mostly gone, plus a 10% gain on AVG FPS and 17% gain on 1% lows and almost 300%(!) gain on 0.1% lows.
The 32GB RAM XMP profile is 5600mhz, but this laptop doesn't not support XMP, so the clock is maxed at 4800mhz (which also is the max the 13500HX supports officially). Higher capacity, dual rank chips and the tighter timings are the main benefits from the 32GB kit.
I also tested other games but didn't include it in the video because there's no performance difference, namely, CS2, 3DMark (TimeSpy Extreme CPU Test and CPU Profile), and Batman Arkham Knight. Overall, the improvement on Spider-Man alone is worth upgrading to 32GB, perhaps also some newer games like Hogwart's Legacy may benefit.
(First video in years. Bought a new laptop with 16GB RAM and felt it was not enough for my current needs, so I planned to upgrade it to 32GB. Then I decided to also make a comparison video for the sake of it. It ended up a much bigger project than I imagined. I have to learn to setup scripts for some games with no in-game benchmarks (e.g. Dota2, Factorio) to maintain consistency. Also there's some variance between the testings which stumped me, and it seems in some tests, it's because of the temps of the CPU and GPU, given that it is a laptop, it has limited cooling capacity - performance is then heavily affected by system temps.
This took me several days but now finally finished it. )
