Quick Answers

So, is Core i7-860S better than Core 2 Duo T6600?

Yes. Core i7-860S is the better all-around CPU here. It gives you a 8.7% average FPS lead across 37 shared CPU game tests in our data, 280.6% better Geekbench multi-core, 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 i7-860S is the better pick. According to our tests, it delivers 8.7% more average FPS across 37 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i7-860S is the stronger fit. You are getting 280.6% better Geekbench multi-core, backed by 4 cores and 8 threads. It also has the larger cache pool with 300% larger total L3 cache (8 MB vs 2 MB).

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

Core i7-860S is the better buy right now. Core i7-860S comes in at an unclear MSRP at $299 MSRP versus unclear MSRP, and it still gives you a 8.7% average FPS lead across 37 shared CPU game tests in our data. It is also 100.0% better value on MSRP (7.8 vs 0.0 PassMark/$), 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 i7-860S makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009), 300% larger total L3 cache (8 MB vs 2 MB), and more multi-core headroom with 4 cores / 8 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
