Quick Answers

So, is Core i7-620UM better than Celeron G1101?

Yes. Core i7-620UM is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data, 55.6% better Geekbench multi-core, 0.5% 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 0.2% 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 55.6% better Geekbench multi-core, backed by 2 cores and 4 threads. It also has the larger cache pool with 100% larger total L3 cache (4 MB vs 2 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 456.0% more expensive on MSRP at $278 MSRP versus $50 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Celeron G1101 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 453.5% better value on paper (21.7 vs 3.9 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.

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 100% larger total L3 cache (4 MB vs 2 MB) and more multi-core headroom with 2 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
