Quick Answers

So, is Core i5-8279U better than Core i7-7700T?

It depends on what you want from the system. For gaming, Core i5-8279U is ahead with a 2.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-7700T pulls ahead with 0.7% better PassMark. Core i7-7700T also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

For streaming, content creation, and heavier multitasking, Core i7-7700T is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Core i5-8279U is still the much better call for a fresh build. Core i5-8279U comes in at an unclear MSRP at unclear MSRP versus $303 MSRP, and it still gives you a 2.8% average FPS lead across 50 shared CPU game tests in our data. Core i7-7700T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (24.8 vs 0.0 PassMark/$), 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 i5-8279U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017). That makes it the safer long-term bet.
