Core m5-6Y54 vs Turion II Ultra M660: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core m5-6Y54

2015

Why buy it

  • +0.7% higher PassMark.
  • 100+% more PCIe lanes (10 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with HD Graphics 515, while Turion II Ultra M660 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Turion II Ultra M660 across 50 shared CPU benchmark tests.
  • Launch MSRP is still $281 MSRP, while Turion II Ultra M660 mostly shows up through inconsistent older-market listings.
  • 125% higher power demand at 4.5W vs 2W.

Turion II Ultra M660

2009

Why buy it

  • Better for gaming: +3.0% higher average FPS across 50 shared CPU benchmark tests.
  • Draws 2W instead of 5W, a 3W reduction.

Trade-offs

  • Lower PassMark (2,278 vs 2,294).
  • No integrated graphics, while Core m5-6Y54 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core m5-6Y54 better than Turion II Ultra M660?
It depends on what you want from the system. For gaming, Turion II Ultra M660 is ahead with a 3.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core m5-6Y54 pulls ahead with 0.7% better PassMark.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core m5-6Y54 is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core m5-6Y54 is the better buy right now. Core m5-6Y54 comes in at an unclear MSRP at $281 MSRP versus unclear MSRP, and it still gives you 0.7% better PassMark. The compromise is that Turion II Ultra M660 is still the better pure gaming CPU with a 3.0% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (8.2 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core m5-6Y54 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009) and more multi-core headroom with 2 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
