  • Lower PassMark (805 vs 845).

Pentium T3400

2008

Why buy it

  • Better for gaming: +6.5% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

  • Smaller total L3 cache (1 MB vs 2 MB).
  • Lower PassMark per dollar, at 5.6 vs 9.4 PassMark/$ ($150 MSRP vs $86 MSRP).
  • 105.9% higher power demand at 35W vs 17W.
  • No integrated graphics, while Celeron 877 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium T3400 better than Celeron 877?
Yes. Pentium T3400 is the better all-around CPU here. It gives you a 6.5% average FPS lead across 50 shared CPU game tests in our data and 5% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Pentium T3400 is the better pick. According to our tests, it delivers 6.5% 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, Pentium T3400 is the stronger fit. You are getting 5% better PassMark.
Which one is the smarter buy today, not just the cheaper CPU?
Pentium T3400 is the easy recommendation for a fresh desktop build. Pentium T3400 comes in 74.4% more expensive on MSRP at $150 MSRP versus $86 MSRP, and it still gives you a 6.5% average FPS lead across 50 shared CPU game tests in our data. Celeron 877 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, especially when the gap is already 6.5% in the shared gaming data.
Which one is more future-proof for 2026 and beyond?
Celeron 877 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2008) and 100% larger total L3 cache (2 MB vs 1 MB). That makes it the safer long-term bet.
