64GB won't help your Chrome tabs much.

Probably not. 50 Chrome tabs might eat 4–8GB depending on extensions and what’s in them. You already have 32GB. That’s more than enough headroom.

The real question is what else you’re running. If you’ve got a VM, Docker, a dozen Slack windows, and a video call going, then sure, 64GB might smooth things out. But if it’s just Chrome and a text editor? You’re throwing money at a problem that doesn’t exist.

Chrome’s memory management is the actual bottleneck, not your RAM capacity. Adding more RAM doesn’t make Chrome smarter about leaked memory or tab discarding. You’d be better off using OneTab, The Great Suspender, or just closing tabs you don’t need.

Upgrading to 2×32GB only makes sense if you’re also doing heavy creative work or running multiple VMs. For tabs alone, you’re fine.
