❌Lower PassMark (5,607 vs 5,625).
❌Less compelling for workstation-style loads than Opteron 6238, which brings 12 cores / 12 threads.

Opteron 6238

2011

Why buy it

✅Better for gaming: +3.7% higher average FPS across 33 shared CPU benchmark tests.
✅Better for workstations and heavier parallel workloads: 12 cores / 12 threads.

Trade-offs

❌Launch MSRP is still $455 MSRP, while Core i7-3820QM mostly shows up through inconsistent older-market listings.
❌155.6% higher power demand at 115W vs 45W.
❌No integrated graphics, while Core i7-3820QM can still boot and troubleshoot without a discrete GPU.
