Quick Answers

So, is Core i3-1305U better than Core i7-7700?

It depends on what you want from the system. For gaming, Core i7-7700 is ahead with a 13.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-1305U pulls ahead with 205.8% better Cinebench R23 multi-core. Core i3-1305U also has the bigger cache pool with 25% larger total L3 cache (10 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Core i3-1305U is the stronger fit. You are getting 205.8% better Cinebench R23 multi-core, backed by 5 cores and 6 threads. It also has the larger cache pool with 25% larger total L3 cache (10 MB vs 8 MB).

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

Core i3-1305U is still the much better call for a fresh build. Core i3-1305U comes in at an unclear MSRP at unclear MSRP versus $272 MSRP, and it still gives you 205.8% better Cinebench R23 multi-core. Core i7-7700 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (31.8 vs 0.0 PassMark/$), 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 i3-1305U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017), a healthier platform with FCBGA1744 and DDR5 instead of LGA1151, 25% larger total L3 cache (10 MB vs 8 MB), and more multi-core headroom with 5 cores / 6 threads instead of 4/8. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
