Quick Answers

So, is Core i7-4650U better than Phenom II X4 840?

Yes. Core i7-4650U is the better all-around CPU here. It gives you a 0.8% average FPS lead across 50 shared CPU game tests in our data, 0.6% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-4650U is the better pick. According to our tests, it delivers 0.8% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i7-4650U is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 4 threads.

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

Core i7-4650U still makes the most sense overall. Core i7-4650U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.8% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-4650U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2011) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
