Quick Answers

So, is Core i5-655K better than Athlon II X4 615e?
Yes. Core i5-655K is the better all-around CPU here. It gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data and 7.7% better Geekbench multi-core, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i5-655K is the better pick. According to our tests, it delivers 2.7% 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 i5-655K is the stronger fit. You are getting 7.7% better Geekbench multi-core, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-655K is still the much better call for a fresh build. Core i5-655K comes in 16.1% more expensive on MSRP at $216 MSRP versus $186 MSRP, and it still gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data. Athlon II X4 615e only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 16.2% better value on paper (10.8 vs 9.3 PassMark/$), 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 i5-655K is the safer long-term CPU choice because it gives you more room to grow and a better platform outlook.
