✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while Pentium E6600 needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,189 vs 1,194).

Pentium E6600

2010

Why buy it

✅+0.4% higher PassMark.

Trade-offs

❌Launch MSRP is still $84 MSRP, while Atom Z3770 mostly shows up through inconsistent older-market listings.
❌712.5% higher power demand at 65W vs 8W.
❌No integrated graphics, while Atom Z3770 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom Z3770 better than Pentium E6600?

It depends on what you want from the system. For gaming, Atom Z3770 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, Pentium E6600 pulls ahead with 0.4% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Pentium E6600 is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

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

Atom Z3770 is still the much better call for a fresh build. Atom Z3770 comes in at an unclear MSRP at unclear MSRP versus $84 MSRP, and it still gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data. Pentium E6600 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (14.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Atom Z3770 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2010). That makes it the safer long-term bet.
