Core i7-640UM

2010

Why buy it

✅Draws 18W instead of 130W, a 112W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Ironlake), while Xeon W3505 needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

Xeon W3505

2009

Why buy it

Trade-offs

❌Lower PassMark (1,163 vs 1,168).
❌622.2% higher power demand at 130W vs 18W.
❌No integrated graphics, while Core i7-640UM can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-640UM better than Xeon W3505?

Not really, because they are built for different jobs. Xeon W3505 makes more sense for workstation-style multi-core throughput, while Core i7-640UM is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i7-640UM is the better pick. According to our tests, it delivers 0.3% 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 i7-640UM is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads.

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

Core i7-640UM still makes the most sense overall. Core i7-640UM comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-640UM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 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.
