Quick Answers

So, is Pentium 6805 better than Core i5-3450S?

It depends on what you want from the system. For gaming, Core i5-3450S is ahead with a 8.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium 6805 pulls ahead with 0.6% better PassMark. Core i5-3450S also has the bigger cache pool with 50% larger total L3 cache (6 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 0.6% 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 $13 cheaper on MSRP at $161 MSRP versus $174 MSRP, and it still gives you 0.6% better PassMark. The compromise is that Core i5-3450S is still the better pure gaming CPU with a 8.5% average FPS lead across 50 shared CPU game tests in our data. It is also 8.7% better value on MSRP (27.5 vs 25.3 PassMark/$), 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 2012) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
