Quick Answers

So, is Core i5-1145G7 better than Core i5-8600T?

Yes. Core i5-1145G7 is the better all-around CPU here. It gives you a 14.2% average FPS lead across 50 shared CPU game tests in our data, 12.1% better Cinebench R23 multi-core, 0.7% higher 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 i5-1145G7 is the better pick. According to our tests, it delivers 14.2% 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 i5-1145G7 is the stronger fit. You are getting 12.1% better Cinebench R23 multi-core, backed by 4 cores and 8 threads.

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

Core i5-1145G7 is still the much better call for a fresh build. Core i5-1145G7 comes in at an unclear MSRP at unclear MSRP versus $213 MSRP, and it still gives you a 14.2% average FPS lead across 50 shared CPU game tests in our data. Core i5-8600T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (43.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i5-1145G7 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2018) 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.
