Quick Answers

So, is Athlon II X2 245e better than Pentium G640T?

Yes. Athlon II X2 245e is the better all-around CPU here. It gives you a 5.1% average FPS lead across 50 shared CPU game tests in our data and 0.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Athlon II X2 245e is the better pick. According to our tests, it delivers 5.1% 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, Athlon II X2 245e is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 2 threads.

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

Athlon II X2 245e is still the much better call for a fresh build. Athlon II X2 245e comes in 35.9% more expensive on MSRP at $87 MSRP versus $64 MSRP, and it still gives you a 5.1% average FPS lead across 50 shared CPU game tests in our data. Pentium G640T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 35.7% better value on paper (17.8 vs 13.1 PassMark/$), 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?

Pentium G640T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2010). That makes it the safer long-term bet.
