Quick Answers

So, is Core i3-7101E better than Core i7-2820QM?
It depends on what you want from the system. For gaming, Core i7-2820QM is ahead with a 5.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-7101E pulls ahead with 1.2% better PassMark. Core i7-2820QM also has the bigger cache pool with 166.7% larger total L3 cache (8 MB vs 3 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i3-7101E is the stronger fit. You are getting 1.2% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-7101E is the better buy right now. Core i3-7101E comes in $451 cheaper on MSRP at $117 MSRP versus $568 MSRP, and it still gives you 1.2% better PassMark. The compromise is that Core i7-2820QM is still the better pure gaming CPU with a 5.0% average FPS lead across 50 shared CPU game tests in our data. It is also 391.1% better value on MSRP (37.9 vs 7.7 PassMark/$), 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 i3-7101E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2011) and more multi-core headroom with 2 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
