Core i7-640UM

2010

Why buy it

✅Draws 18W instead of 65W, a 47W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Ironlake), while Pentium E6800 needs a discrete GPU.

Trade-offs

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

Pentium E6800

2010

Why buy it

Trade-offs

❌Lower PassMark (1,155 vs 1,168).
❌Launch MSRP is still $86 MSRP, while Core i7-640UM mostly shows up through inconsistent older-market listings.
❌261.1% higher power demand at 65W 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 Pentium E6800?

Yes. Core i7-640UM is the better all-around CPU here. It gives you a 2.5% average FPS lead across 50 shared CPU game tests in our data, 1.1% 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 i7-640UM is the better pick. According to our tests, it delivers 2.5% 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 1.1% better PassMark, backed by 2 cores and 4 threads.

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

Core i7-640UM is still the much better call for a fresh build. Core i7-640UM comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you a 2.5% average FPS lead across 50 shared CPU game tests in our data. Pentium E6800 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (13.4 vs 0.0 PassMark/$), 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 i7-640UM makes more sense long term for 2026 and beyond. You are getting 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.
