Quick Answers

So, is Pentium 6805 better than Core i7-2820QM?

It depends on what you want from the system. For gaming, Core i7-2820QM is ahead with a 16.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium 6805 pulls ahead with 1% better PassMark. Core i7-2820QM also has the bigger cache pool with 100% larger total L3 cache (8 MB vs 4 MB).

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

For streaming, content creation, and heavier multitasking, Pentium 6805 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 4 threads.

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

Pentium 6805 is the better buy right now. Pentium 6805 comes in $407 cheaper on MSRP at $161 MSRP versus $568 MSRP, and it still gives you 1% better PassMark. The compromise is that Core i7-2820QM is still the better pure gaming CPU with a 16.8% average FPS lead across 50 shared CPU game tests in our data. It is also 256.4% better value on MSRP (27.5 vs 7.7 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium 6805 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 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.
