AMD Opteron 6282 SE vs Intel Core i3-9300 Comparison

# AMD Opteron 6282 SE vs Intel Core i3-9300

The AMD Opteron 6282 SE and Intel Core i3-9300 represent two very different eras of processor design, yet their benchmark results place them in the same performance tier. The Opteron, a 16-core server chip from the Bulldozer generation, and the i3-9300, a 4-core desktop part from Coffee Lake, both land at the 39th percentile among all CPUs, with average benchmark scores of 1569 and 1554 respectively. This close overall parity, despite a 12-core difference, makes for a revealing comparison of architecture efficiency versus raw core count.

FAQ

Q: Which processor has more cores?

A: The AMD Opteron 6282 SE has 16 cores and 16 threads, while the Intel Core i3-9300 has 4 cores and 4 threads. The Opteron offers four times the core count of the i3-9300.

Where Each One Wins

The AMD Opteron 6282 SE wins all six head-to-head benchmark comparisons against the Intel Core i3-9300, but the margins are consistently narrow. The largest single advantage comes in Cinebench R15 single-core, where the Opteron scores 77 against the i3-9300's 76, a 1.3% difference. In multi-core workloads, the Opteron leads by 0.9% in R15 (546 vs 541), 1% in R20 (2279 vs 2257), and 1% in R23 (5427 vs 5374). The single-core margins in R20 and R23 are 0.9% (321 vs 318) and 1.1% (766 vs 758) respectively.

Despite winning every tested benchmark, the Opteron's victories are so small that they fall within typical run-to-run variance. The i3-9300's strengths lie not in benchmark wins but in efficiency and platform features. It consumes 62 W TDP versus the Opteron's 140 W, uses a smaller 126 mm² die compared to the Opteron's dual-die 2x 315 mm² design, and supports PCIe Gen 3 with 16 CPU lanes, while the Opteron is limited to PCIe Gen 2. The i3-9300 also includes integrated UHD 630 graphics, which the Opteron lacks entirely.

For applications that are sensitive to memory bandwidth per thread, the Opteron's quad-channel DDR3 configuration provides 51.2 GB/s, which is 33% higher than the i3-9300's dual-channel DDR4 at 38.4 GB/s. However, the i3-9300's higher base clock of 3.70 GHz versus 2.60 GHz gives it an advantage in lightly threaded tasks that do not scale with core count.

Architecture Differences

The architecture gap between these two processors is substantial. The Opteron 6282 SE uses AMD's Bulldozer architecture, codenamed Interlagos, built on a 32 nm process with 2,400 million transistors spread across two dies, each measuring 315 mm². Bulldozer was designed around shared modules, with the Opteron's 16 cores organized into 8 modules, each sharing a 2 MB L2 cache. The L1 cache totals 768 KB, and each die has 8 MB of L3 cache.

The Intel Core i3-9300 uses the Coffee Lake architecture, codenamed Coffee Lake, built on Intel's 14 nm process with a single 126 mm² die. Each of its 4 cores has dedicated 64 KB L1 and 256 KB L2 caches, and all cores share an 8 MB L3 cache. Coffee Lake is a refinement of Intel's Core architecture, focusing on high clock speeds and strong single-thread performance per core.

The memory controllers reflect the different eras: the Opteron uses DDR3 with a quad-channel bus, while the i3-9300 uses DDR4 with a dual-channel bus. Despite the newer memory type, the i3-9300's dual-channel configuration provides lower peak bandwidth. The Opteron also lacks integrated graphics, while the i3-9300 includes UHD 630 graphics. In terms of PCIe, the i3-9300 offers Gen 3 with 16 CPU lanes, whereas the Opteron is limited to Gen 2. The Opteron's server heritage is also evident in its Socket G34 platform, compared to the i3-9300's Socket 1151.

The specification tables reveal the fundamental differences in design philosophy. The Opteron 6282 SE uses its 16 cores and higher memory bandwidth to compensate for a much lower clock speed and older process node. The i3-9300 counters with a 1.1 GHz higher base clock, 1.0 GHz higher boost clock, and a 78 W lower TDP. The i3-9300's die is less than one-fifth the size of the Opteron's combined die area, and it includes integrated graphics that the Opteron does not have.

Head-to-Head Benchmarks

The benchmark data shows a remarkably consistent pattern: the AMD Opteron 6282 SE wins every test, but by margins that are almost negligible. In Cinebench R15 multi-core, the Opteron scores 546 against the i3-9300's 541, a 0.9% lead. The single-core R15 test shows the Opteron at 77 versus 76, a 1.3% advantage. This is the largest margin in any benchmark.

Moving to Cinebench R20, the Opteron leads 2279 to 2257 in multi-core, a 1% difference, and 321 to 318 in single-core, a 0.9% difference. The Cinebench R23 results continue the trend: the Opteron scores 5427 in multi-core versus 5374 for the i3-9300, a 1% lead, and 766 versus 758 in single-core, a 1.1% lead.

What is striking about these results is that the Opteron's 16 cores do not translate into a significant multi-core advantage. In fact, the i3-9300's 4 cores nearly match the Opteron's 16 cores in every multi-threaded test. The i3-9300's per-core performance is substantially higher, as evidenced by its 4.30 GHz boost clock compared to the Opteron's 3.30 GHz. The Opteron's multi-core wins are consistent but small, suggesting that Bulldozer's module-based design did not scale efficiently.

The single-core results are even more telling. The Opteron, despite a 2.60 GHz base clock and an older architecture, manages to edge out the i3-9300 in single-core tests by 1.3% or less. This is counterintuitive given the i3-9300's significantly higher clock speeds and modern architecture. The benchmark data suggests that the Opteron's large shared L3 cache and quad-channel memory bandwidth help in these workloads, though the margins are within the noise of typical benchmark variance.

The Verdict

The benchmark data presents a clear statistical picture: the AMD Opteron 6282 SE wins all six head-to-head comparisons, but the Intel Core i3-9300 is so close that the differences are practically negligible. The Opteron's largest win is 1.3% in Cinebench R15 single-core, and its smallest is 0.9% in R15 multi-core and R20 single-core. For any real-world application, these margins would be imperceptible.

The choice between these two processors should be guided by platform requirements and workload characteristics. The Opteron 6282 SE is a server part with 16 cores, quad-channel DDR3 memory, and a 140 W TDP. It is designed for multi-threaded server workloads where its memory bandwidth and core count are assets. However, its 32 nm Bulldozer architecture is inefficient, as evidenced by its performance parity with a 4-core desktop chip.

The Intel Core i3-9300 offers better efficiency, with a 62 W TDP and a 126 mm² die, and includes integrated graphics and PCIe Gen 3 support. Its higher clock speeds make it suitable for desktop use where single-thread performance is important, and its ECC memory support adds flexibility for entry-level workstation tasks.

For users with an existing Socket G34 platform, the Opteron 6282 SE provides a capable server processor with 16 cores. For those building a new system, the i3-9300 offers comparable performance with lower power consumption, a smaller footprint, and modern platform features. The data shows that core count alone is not a reliable predictor of performance: the 16-core Opteron is only 1% faster than the 4-core i3-9300 in multi-threaded workloads. The i3-9300 is the more sensible choice for most applications, while the Opteron makes sense only for legacy server environments that require its specific platform features.
