Quick Answers

So, is Pentium G645T better than Core 2 Duo E4600?

Yes. Pentium G645T is the better all-around CPU here. It gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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, Pentium G645T is the better pick. According to our tests, it delivers 1.7% 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 G645T is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G645T is the better buy right now. Pentium G645T comes in $69 cheaper on MSRP at $64 MSRP versus $133 MSRP, and it still gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data. It is also 108.3% better value on MSRP (19.3 vs 9.3 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium G645T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2007) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
