A4 PRO-7300B

2014

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon HD 8470D, while Pentium G645 needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Pentium G645.

Trade-offs

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

Pentium G645

2012

Why buy it

Trade-offs

❌Lower PassMark (1,450 vs 1,458).
❌Launch MSRP is still $80 MSRP, while A4 PRO-7300B mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while A4 PRO-7300B can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike A4 PRO-7300B.

Quick Answers

So, is A4 PRO-7300B better than Pentium G645?

Yes. A4 PRO-7300B is the better all-around CPU here. It gives you a 2.6% average FPS lead across 49 shared CPU game tests in our data, 0.6% 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, A4 PRO-7300B is the better pick. According to our tests, it delivers 2.6% 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, A4 PRO-7300B is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

A4 PRO-7300B is still the much better call for a fresh build. A4 PRO-7300B comes in at an unclear MSRP at unclear MSRP versus $80 MSRP, and it still gives you a 2.6% average FPS lead across 49 shared CPU game tests in our data. Pentium G645 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (18.1 vs 0.0 PassMark/$), 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?

A4 PRO-7300B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012) 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.
