Quick Answers

So, is Core i7-620UM better than Core i3-350M?
Yes. Core i7-620UM is the better all-around CPU here. It gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data, 7.7% better Geekbench multi-core, 0.3% higher PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i7-620UM is the better pick. According to our tests, it delivers 0.5% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-620UM is the stronger fit. You are getting 7.7% better Geekbench multi-core, backed by 2 cores and 4 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-620UM is still the much better call for a fresh build. Core i7-620UM comes in 113.8% more expensive on MSRP at $278 MSRP versus $130 MSRP, and it still gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data. Core i3-350M only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 113.3% better value on paper (8.4 vs 3.9 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.
Which one is more future-proof for 2026 and beyond?
Core i7-620UM makes more sense long term for 2026 and beyond. You are getting 33.3% larger total L3 cache (4 MB vs 3 MB) and more multi-core headroom with 2 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
