Core i7-640LM vs Phenom II X3 705e: Pros, Cons & Final Verdict

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

Core i7-640LM

2010

Why buy it

✅Draws 25W instead of 65W, a 40W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Ironlake), while Phenom II X3 705e needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (4 MB vs 6 MB).

Phenom II X3 705e

2009

Why buy it

✅+50% larger total L3 cache (6 MB vs 4 MB).

Trade-offs

❌Lower PassMark (1,519 vs 1,529).
❌160% higher power demand at 65W vs 25W.
❌No integrated graphics, while Core i7-640LM can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-640LM better than Phenom II X3 705e?

Yes. Core i7-640LM is the better all-around CPU here. It gives you a 0.6% 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 i7-640LM is the better pick. According to our tests, it delivers 0.6% 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 i7-640LM 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 i7-640LM still makes the most sense overall. Core i7-640LM comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-640LM 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 3/3. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
