Quick Answers

So, is Core i3-2340UE better than Core i3-540?

It depends on what you want from the system. For gaming, Core i3-2340UE is ahead with a 0.4% average FPS lead across 46 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-540 pulls ahead with 0.6% better PassMark. Core i3-540 also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core i3-540 is the stronger fit. You are getting 0.6% 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 i3-2340UE is still the much better call for a fresh build. Core i3-2340UE comes in 50.4% more expensive on MSRP at $200 MSRP versus $133 MSRP, and it still gives you a 0.4% average FPS lead across 46 shared CPU game tests in our data. Core i3-540 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 51.3% better value on paper (11.7 vs 7.7 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.

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

Core i3-2340UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010). That makes it the safer long-term bet.
