2011

Why buy it

✅+33.3% larger total L3 cache (8 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 16 cores / 16 threads.

Trade-offs

❌Lower PassMark (5,643 vs 5,710).
❌Launch MSRP is still $639 MSRP, while Core i7-3740QM mostly shows up through inconsistent older-market listings.
❌155.6% higher power demand at 115W vs 45W.

Quick Answers

So, is Core i7-3740QM better than Opteron 6274?

Not really, because they are built for different jobs. Opteron 6274 makes more sense for workstation-style multi-core throughput, while Core i7-3740QM is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i7-3740QM is the better pick. According to our tests, it delivers 0.7% 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, Core i7-3740QM is the stronger fit. You are getting 1.2% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-3740QM is still the faster CPU overall, but Opteron 6274 is easier to justify if budget matters more than peak performance. Core i7-3740QM comes in at an unclear MSRP at unclear MSRP versus $639 MSRP, and it still gives you a 0.7% average FPS lead across 50 shared CPU game tests in our data. Opteron 6274 is also 100.0% better value on MSRP (8.8 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i7-3740QM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011) and more multi-core headroom with 4 cores / 8 threads instead of 16/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
