Core 2 Quad Q8300

2008

Why buy it

Trade-offs

❌Lower PassMark (1,917 vs 1,943).
❌Launch MSRP is still $179 MSRP, while Core i5-520UM mostly shows up through inconsistent older-market listings.
❌427.8% higher power demand at 95W vs 18W.
❌No integrated graphics, while Core i5-520UM can still boot and troubleshoot without a discrete GPU.

Core i5-520UM

2010

Why buy it

✅+1.4% higher PassMark.
✅Draws 18W instead of 95W, a 77W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Ironlake), while Core 2 Quad Q8300 needs a discrete GPU.

Quick Answers

So, is Core i5-520UM better than Core 2 Quad Q8300?

It depends on what you want from the system. For gaming, Core 2 Quad Q8300 is ahead with a 2.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-520UM pulls ahead with 1.4% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-520UM is the stronger fit. You are getting 1.4% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-520UM is still the much better call for a fresh build. Core i5-520UM comes in at an unclear MSRP at unclear MSRP versus $179 MSRP, and it still gives you 1.4% better PassMark. Core 2 Quad Q8300 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (10.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Core i5-520UM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008) 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.
