Quick Answers

So, is Core i9-13900HX better than Core i7-9700K?

Yes. Core i9-13900HX is the better overall CPU here. You are getting a 14.7% average FPS lead across 16 shared CPU game tests in our data, 194.8% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.

Which one is better for gaming?

If gaming is the priority, Core i9-13900HX is the better pick here. According to our tests, it delivers 14.7% more average FPS across 16 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i9-13900HX is the better fit. You are getting 194.8% better PassMark, backed by 24 cores and 32 threads. It also carries the larger cache pool with 200% larger total L3 cache (36 MB vs 12 MB).

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

Core i9-13900HX is the smarter buy by a wide margin for a fresh build. Core i9-13900HX is at an unclear MSRP at unclear MSRP versus $385 MSRP, and it gives you a 14.7% average FPS lead across 16 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (37.4 vs 0.0 PassMark/$), 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 i9-13900HX is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2018), a healthier platform with FCBGA1964 and DDR5 instead of LGA1151, 200% larger total L3 cache (36 MB vs 12 MB), and more multi-core headroom with 24 cores / 32 threads instead of 8/8. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks
