Quick Answers

So, is Core i7-2620M better than Core i3-3245?
Yes. Core i7-2620M is the better all-around CPU here. It gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data and 0.5% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i7-2620M is the better pick. According to our tests, it delivers 0.9% 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 i7-2620M is the stronger fit. You are getting 0.5% better PassMark, 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 i7-2620M is still the much better call for a fresh build. Core i7-2620M comes in 188.3% more expensive on MSRP at $346 MSRP versus $120 MSRP, and it still gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data. Core i3-3245 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 186.9% better value on paper (20.1 vs 7.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.
Which one is more future-proof for 2026 and beyond?
Core i3-3245 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2011). That makes it the safer long-term bet.
