✅Integrated graphics onboard with Radeon HD 6480G, while Pentium G645T needs a discrete GPU.

Trade-offs

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

Pentium G645T

2012

Why buy it

Trade-offs

❌Lower PassMark (1,238 vs 1,241).
❌Launch MSRP is still $64 MSRP, while A4-3320M mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while A4-3320M can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is A4-3320M better than Pentium G645T?

Yes. A4-3320M is the better all-around CPU here. It gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data and 0.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, A4-3320M is the better pick. According to our tests, it delivers 1.6% 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, A4-3320M 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?

A4-3320M is still the much better call for a fresh build. A4-3320M comes in at an unclear MSRP at unclear MSRP versus $64 MSRP, and it still gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data. Pentium G645T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (19.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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 2011). That makes it the safer long-term bet.
