AMD Opteron 4280 vs Intel Xeon D-1518 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Xeon D-1518 wins every recorded comparison against the AMD Opteron 4280. Across all six Cinebench tests, the Xeon D-1518 holds a consistent advantage, with the largest margins appearing in single-core workloads. The most striking result is in Cinebench R15 single-core, where both processors post an identical score of 54, a statistical tie despite the Xeon D-1518 being credited with the win by the database’s tie-breaking rule.

The multi-core results tell a similar story with slightly larger margins. In Cinebench R15 multi-core, the Xeon D-1518 scores 390 against the Opteron’s 385, a 1.3% lead. That same 1.3% delta repeats across every other test where the scores are not tied: Cinebench R20 multi-core (1628 vs 1607), Cinebench R20 single-core (229 vs 226), Cinebench R23 multi-core (3877 vs 3828), and Cinebench R23 single-core (547 vs 540). The consistency of that 1.3% figure across four of the six tests suggests a stable, per-clock advantage rather than a workload-specific quirk.

What is notable is the narrowness of the margins. Despite the Opteron 4280 having twice the core count (8 cores vs 4), the Xeon D-1518 still edges ahead in multi-threaded rendering workloads. The Opteron’s higher base clock (2.80 GHz vs 2.20 GHz) and boost capability (up to 3.50 GHz) do not translate into a win anywhere. The data suggests that the Xeon D-1518’s per-core efficiency more than compensates for its core deficit, while the Opteron’s Bulldozer architecture, designed for throughput, fails to leverage its additional modules effectively in these tests.

The single-core results are particularly telling. In Cinebench R20 single-core, the Xeon’s 229 score versus the Opteron’s 226 represents a 1.3% edge. In R23 single-core, the gap is 547 to 540, again 1.3%. These margins, while small in absolute terms, are consistent across generations of the Cinebench suite. The R15 single-core tie at 54 points is the only blemish on the Xeon’s clean sweep, but even there, the database records the Xeon as the winner due to its tie-break policy.

The aggregate benchmark score reinforces the pattern. The Xeon D-1518 averages 1121 across all recorded benchmarks, while the Opteron 4280 averages 1107, a 1.3% difference that mirrors the head-to-head deltas. Both processors sit in the lower third of the database’s CPU rankings, with the Xeon at the 32nd percentile and the Opteron at the 31st percentile. Their nearest rivals confirm the close grouping: the Xeon’s closest competitor is the AMD Athlon 240GE at an identical 1121 average, while the Opteron matches the AMD PRO A12-8870 at 1107.

Architecture Differences

The two processors represent fundamentally different design philosophies and manufacturing eras. The Intel Xeon D-1518 is built on a 14 nm process at Intel’s own foundry, packing 3,200 million transistors into a 246 mm² die. It uses the Broadwell architecture, specifically the Broadwell-DE variant for the Xeon D family. The processor integrates 4 cores with 8 threads via Hyper-Threading, a feature that allows each physical core to handle two instruction streams. Its base clock is 2.20 GHz, and notably, the database lists no boost clock for this part, suggesting it operates at a fixed frequency.

The AMD Opteron 4280, by contrast, is a 32 nm part from GlobalFoundries, with 1,200 million transistors spread across a larger 315 mm² die. It belongs to the Bulldozer architecture family, codenamed Valencia, and is part of the Opteron 4000 series. The chip has 8 physical cores but only 8 threads, meaning no simultaneous multithreading. Its base clock is 2.80 GHz, with a boost clock of 3.50 GHz. The Bulldozer design uses clustered multi-threading, where pairs of cores share certain execution resources, which explains why the core count does not translate into a proportional performance advantage.

Cache hierarchies differ substantially. The Xeon D-1518 provides 64 KB of L1 cache per core, 256 KB of L2 per core, and 1.5 MB of L3 per core, for a total of 6 MB of L3 across four cores. The Opteron 4280 lists 384 KB of L1 (shared across the module pairs), 8 MB of L2, and 8 MB of shared L3. The Xeon’s per-core L3 allocation is more generous on a per-thread basis, which likely contributes to its single-core superiority.

Memory support also diverges. The Xeon D-1518 supports both DDR3 and DDR4 in a dual-channel configuration, while the Opteron 4280 supports only DDR3, also dual-channel. The Opteron’s memory bandwidth is explicitly listed at 25.6 GB/s; the database does not provide a figure for the Xeon. Both processors support ECC memory, a critical feature for server workloads. PCIe connectivity differs as well: the Xeon offers Gen 3 with 24 lanes (CPU only), while the Opteron provides Gen 2 without a lane count listed.

The Xeon D-1518 is soldered into an Intel BGA 1667 package, meaning it is not upgradeable. The Opteron uses AMD Socket C32, a socketed design. The Xeon was released on March 8, 2015, and remains in active production; the Opteron launched on November 13, 2011, and is now end-of-life. The Xeon’s launch MSRP is $193; the Opteron’s is $255. Neither chip has an unlocked multiplier, so overclocking is not an option for either.

The Verdict

The data points to a clear conclusion: the Intel Xeon D-1518 is the superior processor in every measured benchmark. The 1.3% advantage in multi-core and single-core tests is consistent, and while the margin is modest, the Xeon achieves it with half the core count and a lower base clock. This indicates a significantly more efficient architecture and per-core performance profile.

For workloads that rely on single-threaded performance, the Xeon D-1518 is the obvious choice. Its single-core scores of 229 in R20 and 547 in R23 outpaced the Opteron’s 226 and 540, respectively. The R15 single-core tie at 54 is the only point of parity, but the Xeon still takes the win in the database’s records. The Opteron’s higher clocks, including a 3.50 GHz boost, could not overcome the Xeon’s architectural advantages.

For multi-threaded workloads, the Opteron’s extra cores theoretically should have helped, but the data shows otherwise. The Xeon’s 390 vs 385 in R15, 1628 vs 1607 in R20, and 3877 vs 3828 in R23 all favor the Intel part. The Bulldozer architecture’s shared resources between core pairs appear to be a bottleneck, preventing the Opteron from scaling with its core count. The Xeon’s Hyper-Threading, combined with its per-core L3 cache allocation, delivers better real-world throughput.

The production status also favors the Xeon. It remains in active production, while the Opteron is end-of-life. For new deployments or upgrades, the Xeon D-1518 offers a forward-looking platform with DDR4 memory support, PCIe Gen 3, and a smaller 14 nm process. The Opteron is stuck on DDR3 and PCIe Gen 2, limiting its relevance in modern server environments.

The percentile rankings are close (32nd for the Xeon, 31st for the Opteron), and their nearest rivals are similarly matched, but the head-to-head results are decisive. The Xeon D-1518 is the better part, period.

Where Each One Wins

The Intel Xeon D-1518 wins in every recorded benchmark, but the nature of its victories suggests specific use cases where it excels most clearly. The consistent 1.3% lead in multi-core tests, despite a 4-core versus 8-core deficit, points to workloads that are lightly threaded or where per-core efficiency dominates. Single-core performance is the Xeon’s strongest suit: the 229 vs 226 in R20 and 547 vs 540 in R23 show that it handles latency-sensitive tasks, such as database queries or network packet processing, with a slight but repeatable edge.

The Xeon’s 35 W TDP versus the Opteron’s 95 W is a decisive factor for dense server deployments. The lower power draw, combined with active production status and DDR4 support, makes it suitable for modern, power-constrained environments like edge computing or storage servers. The 14 nm process and 3,200 million transistors on a smaller die (246 mm² vs 315 mm²) further indicate a more integrated and efficient design.

The AMD Opteron 4280, despite losing all benchmarks, still has attributes that could matter in specific legacy contexts. Its 8 physical cores, even if inefficient in Cinebench, might offer advantages in workloads that scale well with raw core count and do not rely on per-core cache or single-thread speed. The 8 MB of L2 and 8 MB of shared L3 provide a large aggregate cache, which could benefit certain data-heavy server applications. Its socketed C32 design allows for replacement or upgrade without replacing the motherboard, a consideration for existing infrastructure.

The Opteron’s higher base clock (2.80 GHz) and boost clock (3.50 GHz) mean that in single-threaded tasks that do not stress the architecture’s shared resources, it might match or approach the Xeon’s performance, as evidenced by the R15 single-core tie. Its memory bandwidth of 25.6 GB/s is explicitly listed, while the Xeon’s is not, suggesting the Opteron has a defined, though not necessarily superior, memory throughput capability.

In summary, the Xeon D-1518 is the winner for new builds, power-sensitive environments, and any workload where single-threaded responsiveness or modern platform features (DDR4, PCIe Gen 3) matter. The Opteron 4280 retains relevance only for existing C32 socket systems that require its specific core count or cache configuration, and where the 95 W TDP is acceptable. The benchmark data, however, provides no scenario where the Opteron outperforms the Xeon, making the Intel part the unambiguous recommendation.
