Quick Answers

So, is Core i5-1245U better than Ryzen 3 5300G?

It depends on what you want from the system. For gaming, Core i5-1245U is ahead with a 8.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Ryzen 3 5300G pulls ahead with 0.7% better PassMark. Core i5-1245U also has the bigger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Ryzen 3 5300G is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-1245U is still the faster CPU overall, but Ryzen 3 5300G is easier to justify if budget matters more than peak performance. Core i5-1245U comes in at an unclear MSRP at unclear MSRP versus $130 MSRP, and it still gives you a 8.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Ryzen 3 5300G is still stronger for heavier multi-core work with 0.7% better PassMark. Ryzen 3 5300G is also 100.0% better value on MSRP (100.4 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-1245U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2021), a healthier platform with FCBGA1744 and DDR5 instead of AM4, and 50% larger total L3 cache (12 MB vs 8 MB). That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
