Quick Answers

So, is Core i7-8750H better than Core i7-7740X?

It depends on what you want from the system. For gaming, Core i7-7740X is ahead with a 5.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-8750H pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i7-8750H is the stronger fit. You are getting 0.9% better PassMark, backed by 6 cores and 12 threads.

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

Core i7-8750H is still the much better call for a fresh build. Core i7-8750H comes in at an unclear MSRP at unclear MSRP versus $339 MSRP, and it still gives you 0.9% better PassMark. Core i7-7740X only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (28.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2066.

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

Core i7-8750H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2017) and more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
