Quick Answers

So, is Core i5-6198DU better than Core i7-4578U?

It depends on what you want from the system. For gaming, Core i7-4578U is ahead with a 1.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-6198DU pulls ahead with 1.1% better PassMark. Core i7-4578U also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-6198DU is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-6198DU still makes the most sense overall. Core i5-6198DU comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1.1% better PassMark.

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

Core i5-6198DU makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014) and more multi-core headroom with 2 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
