Quick Answers

So, is Core i3-4370T better than Athlon X4 840?

It depends on what you want from the system. For gaming, Athlon X4 840 is ahead with a 2.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-4370T pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i3-4370T is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-4370T is still the much better call for a fresh build. Core i3-4370T comes in 35.3% more expensive on MSRP at $138 MSRP versus $102 MSRP, and it still gives you 0.9% better PassMark. Athlon X4 840 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 34.1% better value on paper (32.7 vs 24.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM2+.

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

Core i3-4370T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
