Quick Answers

So, is Core i5-1345UE better than Core i7-8700T?

It depends on what matters more to you. For gaming, Core i7-8700T is ahead with a 4.2% average FPS lead across 3 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-1345UE pulls ahead with 1.3% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-1345UE is the better fit. You are getting 1.3% better PassMark, backed by 10 cores and 12 threads.

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

Core i5-1345UE is the smarter buy by a wide margin for a fresh build. Core i5-1345UE is 3.0% more expensive on MSRP at $312 MSRP versus $303 MSRP, and it gives you 1.3% better PassMark. Core i7-8700T only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 1.7% better value on paper (33.7 vs 33.2 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i5-1345UE is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2018), a healthier platform with FCBGA1744 and DDR5 instead of LGA1151, and more multi-core headroom with 10 cores / 12 threads instead of 6/12. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks

Paired with RTX 4090
