Analysis: AMD Opteron 3380 vs AMD Opteron 4376 HE
The Verdict
The AMD Opteron 3380 and AMD Opteron 4376 HE are extremely close performers, but the data consistently favors the 3380. Across all six recorded Cinebench tests, the Opteron 3380 wins outright, with margins ranging from 0.8% to 1.1%. The Opteron 4376 HE does not secure a single victory in the head-to-head comparison. The average benchmark score tells a similar story: the 3380 averages 1071 points, while the 4376 HE averages 1061 points, a gap of about 1%. Both processors sit at the 29th percentile of all CPUs in the database, meaning they occupy the same performance tier relative to the broader market. For users choosing strictly from this data, the Opteron 3380 is the clear pick, though the practical difference is modest. The 4376 HE remains viable if platform compatibility or socket availability favors it, but on raw benchmark performance, the 3380 leads in every measured category.
Architecture Differences
The two processors share several foundational traits but diverge in architecture and socket. The Opteron 3380 uses the K10 architecture with the codename Delhi, part of the Opteron 3000 series. The Opteron 4376 HE uses the Piledriver architecture with the codename Seoul, belonging to the Opteron 4000 series. Both are built on a 32 nm process node, with identical transistor counts of 1,200 million and identical die sizes of 315 mm². The cache layouts match exactly: 384 KB of L1, 8 MB of L2, and 8 MB of shared L3. Both processors feature 8 cores and 8 threads, with base clocks of 2.60 GHz and boost clocks of 3.60 GHz. The TDP is also identical at 65 watts.
The key differentiators are the socket and memory configuration. The Opteron 3380 uses AMD Socket AM3+, while the Opteron 4376 HE uses AMD Socket C32. The 3380 supports dual-channel DDR3 memory with a recorded memory bandwidth of 29.9 GB/s, while the 4376 HE has no memory bus or bandwidth data recorded in the database. The 3380 also lists PCIe Gen 2 support and integrated graphics as a chipset feature on certain motherboards, whereas the 4376 HE has no PCIe or integrated graphics data recorded. The 3380 has a recorded launch MSRP of $229, while the 4376 HE has no launch MSRP recorded. Both processors are server/workstation parts, released on the same date, and neither has an unlocked multiplier.
Head-to-Head Benchmarks
The benchmark results show a consistent, if narrow, advantage for the Opteron 3380. In Cinebench R15 multi-core, the 3380 scores 373 against 369 for the 4376 HE, a 1.1% lead. In single-core R15, both processors score exactly 52, though the database records the 3380 as the winner with a delta of 0%. Moving to Cinebench R20, the 3380 posts 1555 in multi-core versus 1541, a 0.9% edge. In R20 single-core, the 3380 scores 219 against 217, again a 0.9% margin. Cinebench R23 multi-core sees the 3380 at 3704 versus 3670, another 0.9% advantage. Finally, in R23 single-core, the 3380 scores 522 against 518, a 0.8% lead. The largest gap is in R15 multi-core at 1.1%, and the smallest in R23 single-core at 0.8%. These margins are small enough that they may not be perceptible in real-world workloads, but the pattern is unmistakable: the 3380 wins all six recorded comparisons.
The nearest rivals provide additional context. The Opteron 3380 sits alongside the AMD Athlon X4 880K with an identical average score of 1071, and it is within 0.1% of the Intel Core i5-5287U and Intel Core i3-4170T. The Opteron 4376 HE matches the Intel Core i3-4360 at 1061, and is within 0.2% of the AMD FX-8320E. These rival placements suggest both Opterons are competitive with mid-range desktop parts from their era, but neither reaches the upper tiers of modern CPU performance.
FAQ
Q: Which processor has the higher average benchmark score?
A: The AMD Opteron 3380 averages 1071 points, while the AMD Opteron 4376 HE averages 1061 points. The 3380 leads by 10 points, roughly a 1% difference.
Q: Are the core and thread counts the same?
A: Yes, both the Opteron 3380 and the Opteron 4376 HE have 8 cores and 8 threads. Their base clocks are both 2.60 GHz and their boost clocks are both 3.60 GHz.
Q: Do the two processors use the same socket?
A: No. The Opteron 3380 uses AMD Socket AM3+, while the Opteron 4376 HE uses AMD Socket C32. This means they are not directly interchangeable on the same motherboard.
Q: How do they compare in single-core performance?
A: The Opteron 3380 leads in single-core tests. In Cinebench R15, both score 52, but the 3380 is recorded as the winner with a 0% delta. In R20, the 3380 scores 219 versus 217, and in R23 it scores 522 versus 518.
Q: What is the TDP for each processor?
A: Both processors have a TDP of 65 watts. They also share the same 32 nm process node, 1,200 million transistors, and 315 mm² die size.
Q: Which processor has more cache?
A: They are identical in cache. Both have 384 KB of L1, 8 MB of L2, and 8 MB of shared L3.
Where Each One Wins
The data shows a straightforward split: the Opteron 3380 wins everywhere. In multi-core workloads, it leads in R15 by 1.1%, in R20 by 0.9%, and in R23 by 0.9%. For single-core tasks, it leads in R15 by 0% (tied score), in R20 by 0.9%, and in R23 by 0.8%. The 3380 also holds the better average score at 1071 versus 1061. If the workload is purely render-based, as measured by Cinebench, the 3380 is the stronger choice in every scenario.
The Opteron 4376 HE does not have a single recorded win, so it cannot be recommended on benchmark performance alone. However, the differences are small enough that the 4376 HE could still be chosen for platform reasons. The 4376 HE uses Socket C32, while the 3380 uses AM3+, so a system built around C32 motherboards would naturally pair with the 4376 HE. The 4376 HE also has no memory bandwidth or PCIe data recorded, while the 3380 lists a 29.9 GB/s memory bandwidth and PCIe Gen 2 support. This means the 3380 offers more documented platform features, but the 4376 HE may fit into an existing C32 infrastructure. For new builds where the socket is not a constraint, the 3380 is the better performer.
