Core 2 Duo T5800 vs Core i5-3317U: Pros, Cons & Final Verdict

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

Core 2 Duo T5800

2008

Why buy it

  • Draws 2W instead of 512W, a 510W reduction.

Trade-offs

  • Lower PassMark (2,000 vs 2,014).
  • Smaller total L3 cache (2 MB vs 3 MB).
  • No integrated graphics, while Core i5-3317U can still boot and troubleshoot without a discrete GPU.

Core i5-3317U

2012

Why buy it

  • +50% larger total L3 cache (3 MB vs 2 MB).
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Intel HD Graphics 4000, while Core 2 Duo T5800 needs a discrete GPU.

Trade-offs

  • 25500% higher power demand at 512W vs 2W.

Quick Answers

So, is Core i5-3317U better than Core 2 Duo T5800?
Yes. Core i5-3317U is the better all-around CPU here. It gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data, 0.7% 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 i5-3317U is the better pick. According to our tests, it delivers 1.9% 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 i5-3317U is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-3317U still makes the most sense overall. Core i5-3317U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data.
Which one is more future-proof for 2026 and beyond?
Core i5-3317U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2008), 50% larger total L3 cache (3 MB vs 2 MB), 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.
