Quick Answers

So, is Core i7-4770T better than Core i7-3820?

Yes. Core i7-4770T is the better all-around CPU here. It gives you a 3.1% average FPS lead across 50 shared CPU game tests in our data, 1.2% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-4770T is the better pick. According to our tests, it delivers 3.1% 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, Core i7-4770T is the stronger fit. You are getting 1.2% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-4770T is the better buy right now. Core i7-4770T comes in $36 cheaper on MSRP at $250 MSRP versus $286 MSRP, and it still gives you a 3.1% average FPS lead across 50 shared CPU game tests in our data. It is also 15.7% better value on MSRP (23.4 vs 20.2 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i7-4770T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 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.
