I'm planning to upgrade my laptop with a new SSD and noticed the thermal putty on it is looking quite dry and dirty, likely due to dust from the fan. Before I go ahead with the SSD upgrade, I want to replace the thermal putty. I've picked out UPSIREN U6 PRO, but it's a bit pricey at around $19 for just 10 grams. Since thermal putty is meant to fill larger gaps between components, I'm wondering if 10 grams is enough to do the job and cover all the VRAMs? I know thermal putty is different from thermal paste, which I typically use for my CPU die. Can anyone give me some insight on whether 10 grams will suffice or how much I might generally need?

Honestly, 10 grams should be plenty for a single laptop or PC. You can usually re-paste dozens of CPUs and GPUs with that amount! Just ensure you're focusing on the VRAM chips specifically. But if you're concerned about covering everything adequately, it might be worth fetching an extra gram or two just to be safe.
If you're planning to apply new thermal putty throughout your laptop, you might want to consider getting around 20 grams. It’s often necessary to have a bit more on hand for good coverage, especially on VRAMs. 10 grams might leave you a little short depending on the layout and how much putty you actually need to fill those gaps.
