Core i3-2377M

2012

Why buy it

✅Draws 17W instead of 80W, a 63W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 3000, while Pentium 1403 needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,850 vs 1,851).
❌Smaller total L3 cache (3 MB vs 5 MB).
❌Launch MSRP is still $250 MSRP, while Pentium 1403 mostly shows up through inconsistent older-market listings.

Pentium 1403

2012

Why buy it

✅+66.7% larger total L3 cache (5 MB vs 3 MB).

Trade-offs

❌370.6% higher power demand at 80W vs 17W.
❌No integrated graphics, while Core i3-2377M can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium 1403 better than Core i3-2377M?

Yes. Pentium 1403 is the better all-around CPU here. It gives you a 0.7% average FPS lead across 49 shared CPU game tests in our data and 0.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium 1403 is the better pick. According to our tests, it delivers 0.7% more average FPS across 49 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Pentium 1403 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 66.7% larger total L3 cache (5 MB vs 3 MB).

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

Pentium 1403 is the easy recommendation for a fresh desktop build. Pentium 1403 comes in at an unclear MSRP at unclear MSRP versus $250 MSRP, and it still gives you a 0.7% average FPS lead across 49 shared CPU game tests in our data. Core i3-2377M only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Pentium 1403 is the safer long-term CPU choice because it gives you more room to grow and a better platform outlook.
