See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i3-1115G4

2020

Why buy it

✅Draws 15W instead of 115W, a 100W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics for 11th Gen (48 EU), while Opteron 6378 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Opteron 6378 across 50 shared CPU benchmark tests.
❌Lower PassMark (5,860 vs 5,889).
❌Smaller total L3 cache (6 MB vs 8 MB).
❌Less compelling for workstation-style loads than Opteron 6378, which brings 16 cores / 16 threads.

Opteron 6378

2012

Why buy it

✅Better for gaming: +23.9% higher average FPS across 50 shared CPU benchmark tests.
✅+33.3% larger total L3 cache (8 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 16 cores / 16 threads.

Trade-offs

❌666.7% higher power demand at 115W vs 15W.
❌No integrated graphics, while Core i3-1115G4 can still boot and troubleshoot without a discrete GPU.
❌No AVX-512 support for niche heavy compute workloads where it can matter.

Quick Answers

So, is Opteron 6378 better than Core i3-1115G4?

Not really, because they are built for different jobs. Opteron 6378 makes more sense for workstation-style multi-core throughput, while Core i3-1115G4 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Opteron 6378 is the better pick. According to our tests, it delivers 23.9% 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, Opteron 6378 is the stronger fit. You are getting 0.5% better PassMark, backed by 16 cores and 16 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Opteron 6378 still makes the most sense overall. Opteron 6378 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 23.9% average FPS lead across 50 shared CPU game tests in our data.

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

Core i3-1115G4 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2012) and AVX-512 support for heavier modern compute workloads. That makes it the safer long-term bet.
