AMD Opteron 6282 SE vs Intel Core i3-8300T Comparison

The Intel Core i3-8300T and AMD Opteron 6282 SE represent two very different approaches to computing, separated by nearly seven years of architectural evolution and targeting entirely different market segments. The Opteron, a 16-core server behemoth from 2011, dominates the i3-8300T in every single benchmark recorded here, while the Intel part counters with drastically lower power consumption and a much more modern feature set. Benchmark data shows the Opteron 6282 SE winning all six head-to-head tests, with a consistent performance advantage of roughly 14% across both single-core and multi-core workloads.

Where Each One Wins

The AMD Opteron 6282 SE wins everywhere that raw compute throughput matters. In the Cinebench R23 multi-core test, the Opteron scores 5427 against the i3-8300T's 4656, a 14.2% margin. The same pattern repeats in Cinebench R20 multi-core, where the Opteron posts 2279 versus 1955, and in R15 multi-core, where it scores 546 against 469. Even in single-core tests, where Intel traditionally holds an advantage, the Opteron comes out ahead: 766 versus 657 in Cinebench R23 single-core and 321 versus 275 in R20 single-core. This is a complete sweep, with the AMD part winning all six head-to-head benchmarks by margins between 14.1% and 14.3%.

The Intel Core i3-8300T, despite losing every benchmark, offers advantages that don't show up in raw scores. Its 35-watt TDP is a fraction of the Opteron's 140-watt figure, making it suitable for compact desktop builds and low-power systems. The i3-8300T also includes integrated UHD Graphics 630, eliminating the need for a discrete GPU in basic systems. The Opteron 6282 SE, by contrast, has no integrated graphics and targets server/workstation deployments where discrete accelerators are assumed. The Intel part's 14nm process node versus the Opteron's 32nm node also translates to much better efficiency per watt, even if the raw benchmark numbers favor AMD.

Architecture Differences

These processors come from fundamentally different design philosophies. The Intel Core i3-8300T uses the Coffee Lake architecture on a 14nm process, featuring 4 physical cores and 4 threads. Its cache hierarchy consists of 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3 cache. The die size is a compact 126 mm², reflecting Intel's mature 14nm manufacturing. Memory support is DDR4 over a dual-channel bus, delivering 38.4 GB/s of bandwidth. The CPU connects via PCIe Gen 3 with 16 lanes from the CPU.

The AMD Opteron 6282 SE is built on the Bulldozer architecture, codenamed Interlagos, using a 32nm process. It packs 16 cores and 16 threads across a massive dual-die design measuring 2x 315 mm², with 2,400 million transistors. Its cache layout differs significantly: 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. The Opteron supports DDR3 memory across a quad-channel bus, yielding 51.2 GB/s of bandwidth — notably higher than the Intel part's DDR4 dual-channel implementation. PCIe support is Gen 2, reflecting the older platform.

The memory bandwidth disparity is particularly interesting. Despite using older DDR3 technology, the Opteron's quad-channel configuration provides 33% more theoretical bandwidth than the i3-8300T's dual-channel DDR4 setup. This helps explain why the 16-core AMD part maintains its lead even in multi-threaded workloads that stress memory throughput. The i3-8300T's advantage lies in its modern process node and per-core efficiency, though the benchmark data indicates this doesn't translate into a win in any recorded test.

Head-to-Head Benchmarks

The benchmark results are remarkable for their consistency. Across six different Cinebench tests spanning three versions (R15, R20, R23), the AMD Opteron 6282 SE wins every single one by nearly identical margins. This uniformity suggests the performance gap is structural rather than workload-specific.

Starting with Cinebench R15 multi-core, the Opteron scores 546 against the i3-8300T's 469, a 14.1% advantage. The single-core version of the same test shows the Opteron at 77 versus 66, a 14.3% lead. Moving to Cinebench R20, the pattern holds: multi-core scores are 2279 for AMD and 1955 for Intel, while single-core is 321 versus 275. The most recent Cinebench R23 continues the trend with multi-core results of 5427 versus 4656 and single-core of 766 versus 657.

The average benchmark scores tell a similar story. The Opteron 6282 SE averages 1569 across all recorded benchmarks, while the i3-8300T averages 1586 — a difference of about 1.1% in favor of Intel. This appears contradictory to the head-to-head results, but the average includes Geekbench scores for the Intel part, which has two additional benchmarks (Geekbench multi-core at 3436 and single-core at 1171) that the Opteron does not have recorded. The percentile rankings are identical at 39 for both processors, placing them in the same tier relative to all CPUs in the database.

The nearest rivals for each processor reinforce the close overall standings. The i3-8300T's closest competitor is the Intel Core i7-1060G7 with an average score of 1591, just 0.3% ahead. The Opteron 6282 SE's nearest rival is the Intel Core i3-8300 at 1564, a 0.3% gap. Both processors sit in a dense cluster of CPUs scoring between roughly 1560 and 1610, indicating that while the Opteron wins every direct comparison, the overall performance envelope is similar. The Opteron's 16 cores and higher memory bandwidth give it the edge in every Cinebench test, but the i3-8300T's modern architecture keeps it competitive in aggregate scoring despite having 12 fewer cores.
