Quick Answers

So, is Core i5-1155G7 better than Core i5-9600T?

Yes. Core i5-1155G7 is the better all-around CPU here. It gives you a 21.3% average FPS lead across 50 shared CPU game tests in our data, 0.9% 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 i5-1155G7 is the better pick. According to our tests, it delivers 21.3% 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 i5-1155G7 is the stronger fit. You are getting 0.9% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-1155G7 is still the faster CPU overall, but Core i5-9600T is easier to justify if budget matters more than peak performance. Core i5-1155G7 comes in at an unclear MSRP at unclear MSRP versus $213 MSRP, and it still gives you a 21.3% average FPS lead across 50 shared CPU game tests in our data. Core i5-9600T is also 100.0% better value on MSRP (45.1 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-1155G7 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2019) and more multi-core headroom with 4 cores / 8 threads instead of 6/6. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
