  • +50% larger total L3 cache (6 MB vs 4 MB).

Trade-offs

  • Launch MSRP is still $174 MSRP, while Pentium Gold G6505 mostly shows up through inconsistent older-market listings.

Pentium Gold G6505

2021

Why buy it

  • Draws 58W instead of 65W, a 7W reduction.

Trade-offs

  • Lower PassMark (4,371 vs 4,399).
  • Smaller total L3 cache (4 MB vs 6 MB).

Quick Answers

So, is Pentium Gold G6505 better than Core i5-3450S?
It depends on what you want from the system. For gaming, Pentium Gold G6505 is ahead with a 0.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-3450S pulls ahead with 0.6% better PassMark. Core i5-3450S also has the bigger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-3450S is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Pentium Gold G6505 is still the much better call for a fresh build. Pentium Gold G6505 comes in at an unclear MSRP at unclear MSRP versus $174 MSRP, and it still gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data. Core i5-3450S only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (25.3 vs 0.0 PassMark/$), 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 Gold G6505 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2012). That makes it the safer long-term bet.
