Quick Answers

So, is Core i5-8365UE better than Core i7-3770T?

It depends on what you want from the system. For gaming, Core i7-3770T is ahead with a 4.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-8365UE pulls ahead with 0.6% better PassMark. Core i7-3770T also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-8365UE is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-8365UE is still the much better call for a fresh build. Core i5-8365UE comes in 6.8% more expensive on MSRP at $297 MSRP versus $278 MSRP, and it still gives you 0.6% better PassMark. Core i7-3770T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 6.2% better value on paper (19.4 vs 18.3 PassMark/$), 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?

Core i5-8365UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2012) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
