Quick Answers

So, is Core i7-620M better than Athlon II X4 605e?

It depends on what you want from the system. For gaming, Core i7-620M is ahead with a 2.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Athlon II X4 605e pulls ahead with 33.6% better Geekbench multi-core.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Athlon II X4 605e is the stronger fit. You are getting 33.6% better Geekbench multi-core, backed by 4 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-620M is still the much better call for a fresh build. Core i7-620M comes in at an unclear MSRP at unclear MSRP versus $143 MSRP, and it still gives you a 2.5% average FPS lead across 50 shared CPU game tests in our data. Athlon II X4 605e only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (13.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

Which one is more future-proof for 2026 and beyond?

Core i7-620M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009). That makes it the safer long-term bet.
