Tell HN: Impact of using 1 or 2 sticks of DDR5 on a 6800HX with 680M IG

A few months ago, I ordered a Minisforum UM690 for work.

For less than 500 bucks, this little beast is equipped with the incredibly powerful 8 cores / 16 threads Ryzen 9 6900HX (4.9GHz) and an integrated RDN2 680M graphics card (the single thread performance of this mobile CPU is just 10% lower than my home 5800X desktop PC).

I do some light gaming on my lunch break, and I was pretty impressed by the gaming performance of the 680M.

Because of budget constraints at the time of ordering, I could only afford a single stick of Gskill - RipJaws 16 Go DDR5 4800 MHz CL34.

I made a few benchmarks on multiple games, but most games I play do not come with a proper benchmark loop, so I used Unigine Superposition Benchmark to make a proper benchmark.

Single 16 GB stick, 1080p, medium settings: 3022 (18.85 min fps, 22.61 avg fps, 31.85 max fps)

Those results were good for an IGPU, but I saw a few articles saying that having two sticks instead of one could improve performance (never backed up with benchmarks or hard numbers).

So I bought another stick. Here are the results with two sticks:

Dual 16 GB sticks, 1080p, medium settings: 4969 (31.66 min fps, 37.17 avg fps, 48.96 max fps)

Yep, this is a whopping +65% with two sticks!

So, if you use a CPU with an integrated graphics card, you should use 2 sticks!
