Quick Answers

So, is Core 5 120 better than Core i7-9700K?
It depends on what you want from the system. For gaming, Core i7-9700K is ahead with a 19.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 5 120 pulls ahead with 50.2% better PassMark. Core 5 120 also has the bigger cache pool with 50% larger total L3 cache (18 MB vs 12 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core 5 120 is the stronger fit. You are getting 50.2% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (18 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core 5 120 is the better buy right now. Core 5 120 comes in $45 cheaper on MSRP at $340 MSRP versus $385 MSRP, and it still gives you 50.2% better PassMark. The compromise is that Core i7-9700K is still the better pure gaming CPU with a 19.2% average FPS lead across 50 shared CPU game tests in our data. It is also 70.1% better value on MSRP (63.6 vs 37.4 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core 5 120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2018), a healthier platform with LGA1700 and DDR5 instead of LGA1151, 50% larger total L3 cache (18 MB vs 12 MB), and more multi-core headroom with 6 cores / 12 threads instead of 8/8. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
