AMD Opteron 6386 SE vs Intel Core i3-10105T Comparison

The Intel Core i3-10105T and the AMD Opteron 6386 SE represent two vastly different approaches to computing, separated by nearly a decade of architectural evolution. The data shows a surprising outcome: despite having four fewer cores and a significantly lower power envelope, the modern Intel chip nearly matches the aging 16-core server processor in average benchmark score. The Opteron wins every single head-to-head benchmark, but by margins of only 5.5% to 6%, a slim lead that raises questions about the value of raw core counts versus modern single-thread efficiency.

The Verdict

The benchmark data paints a clear picture of generational trade-offs. The AMD Opteron 6386 SE holds a consistent, yet narrow, lead across all six Cinebench tests, winning by margins between 5.5% and 6%. However, the Intel Core i3-10105T posts an average benchmark score of 2058, compared to the Opteron’s 2038, meaning the overall average actually favors the Intel part by roughly 1%. This discrepancy—winning every test yet losing the average—indicates that the Opteron’s victories are concentrated in the Cinebench suite, while the i3’s performance profile is more balanced across other workloads.

For users prioritizing single-thread responsiveness and modern platform features, the i3-10105T is the logical choice. Its 46th percentile ranking versus the Opteron’s 45th shows they sit at nearly the same level in the global CPU landscape, but the Intel part achieves this with 35W TDP and integrated graphics. The Opteron, with its 140W TDP, server-grade ECC memory support, and quad-channel DDR3, makes sense only in legacy server environments where the existing G34 socket infrastructure and 16 physical cores are already in place. The data does not support choosing the Opteron for new builds; its advantages are too small to justify its power and platform costs.

Architecture Differences

The architectural gap between these two processors is immense. The Intel Core i3-10105T is built on a 14nm process at Intel’s foundry, using the Comet Lake-R architecture. It packs 4 cores and 8 threads, with a base clock of 3.00 GHz and a boost clock of 3.90 GHz. Its cache hierarchy is per-core: 64 KB of L1 and 256 KB of L2 per core, with a shared 6 MB L3 cache. It supports dual-channel DDR4 memory with 42.7 GB/s bandwidth and features PCIe Gen 3 with 16 lanes from the CPU. Integrated UHD Graphics 630 is included, and the chip does not support ECC memory.

The AMD Opteron 6386 SE, released in late 2012, uses the Piledriver architecture on a 32nm process from GlobalFoundries. It is a massive 16-core, 16-thread processor with 2,400 million transistors spread across a dual-die design measuring 2x 315 mm². Its base clock is 2.80 GHz with a boost of 3.50 GHz. Cache is organized differently: 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. It supports quad-channel DDR3 memory with 51.2 GB/s bandwidth, offers PCIe Gen 2, and includes ECC memory support. The Opteron has no integrated graphics and targets the server/workstation market segment, with a production status of end-of-life.

Where Each One Wins

The Opteron 6386 SE wins exclusively in the Cinebench suite—all six tests, from R15 to R23, in both single-core and multi-core variants. Its largest margin is a 6% advantage in Cinebench R15 single-core, while its multi-core wins hover around 5.5% to 5.6%. This pattern suggests the Opteron’s 16 physical cores provide a modest throughput advantage in heavily threaded rendering workloads, despite its older architecture and lower clock speeds.

The Intel Core i3-10105T wins in the broader picture, despite losing every head-to-head test. Its Geekbench scores—3649 multi-core and 1265 single-core—are not present in the Opteron’s benchmark list, giving the i3 a data point the Opteron cannot counter. This absence skews the average benchmark score in Intel’s favor. The i3 also wins on efficiency metrics implicitly: a 35W TDP versus 140W, and a modern dual-channel DDR4 platform versus quad-channel DDR3. For everyday desktop workloads, the i3’s higher boost clock of 3.90 GHz and superior IPC from the newer Comet Lake architecture likely close the gap in single-thread tasks, even if Cinebench R15 shows a 6% deficit.

FAQ

Q: Which processor has a higher average benchmark score?

A: The Intel Core i3-10105T has an average benchmark score of 2058, while the AMD Opteron 6386 SE scores 2038, a difference of about 1% in Intel’s favor.

Q: Does the Opteron win every benchmark test?

A: Yes, the AMD Opteron 6386 SE wins all six Cinebench tests listed, with deltas ranging from -5.5% to -6% relative to the Intel chip.

Q: What explains the Opteron’s wins despite the i3’s higher average score?

A: The Opteron’s wins are confined to the Cinebench suite, while the Intel part has additional Geekbench scores that contribute to its higher average. The Opteron has no Geekbench results in the data, so its average relies solely on Cinebench performance.

Q: How do the core counts differ?

A: The AMD Opteron 6386 SE has 16 cores and 16 threads, while the Intel Core i3-10105T has 4 cores and 8 threads.

Q: Which chip supports ECC memory?

A: The AMD Opteron 6386 SE supports ECC memory, while the Intel Core i3-10105T does not.

Q: What are the power consumption figures?

A: The Intel Core i3-10105T has a TDP of 35W, whereas the AMD Opteron 6386 SE has a TDP of 140W.

Head-to-Head Benchmarks

The Opteron’s dominance in Cinebench is consistent but narrow. In Cinebench R15 multi-core, the Opteron scores 710 against the i3’s 670, a 5.6% lead. The single-core R15 test shows a 6% gap, with scores of 100 and 94 respectively. Moving to R20, the Opteron again leads by 5.5% in both multi-core (2959 vs 2795) and single-core (417 vs 394). The pattern holds in R23, where the Opteron posts 7047 multi-core and 994 single-core, versus the i3’s 6656 and 939, both showing a 5.5% delta.

These margins are remarkably consistent, suggesting the Opteron’s advantage is structural rather than workload-specific. The 16-core design provides a steady throughput edge in Cinebench’s rendering tasks, while the older Piledriver cores still manage to edge out Comet Lake in single-thread tests, likely due to a combination of higher base clock (2.80 GHz vs 3.00 GHz is actually lower for AMD, so this is curious) and the specific optimization of the Cinebench workload. However, the i3’s Geekbench scores—3649 multi-core and 1265 single-core—demonstrate that in other benchmark suites, the modern architecture pulls ahead. The data shows that the Opteron’s wins are real but narrow, and entirely within one benchmark family.

Specification Differences

The two processors differ in nearly every specification category. The Intel Core i3-10105T uses 4 cores and 8 threads, while the AMD Opteron 6386 SE uses 16 cores and 16 threads. Base clocks are 3.00 GHz for Intel and 2.80 GHz for AMD, with boost clocks of 3.90 GHz and 3.50 GHz respectively. TDP is a massive differentiator: 35W for Intel versus 140W for AMD. The sockets are incompatible—Intel Socket 1200 versus AMD Socket G34. Process nodes are 14nm for Intel and 32nm for AMD.

Memory support diverges completely: Intel uses dual-channel DDR4 with 42.7 GB/s bandwidth and no ECC, while AMD uses quad-channel DDR3 with 51.2 GB/s bandwidth and ECC support. PCIe generations differ (Gen 3 for Intel, Gen 2 for AMD). The Intel chip includes integrated UHD Graphics 630, while the AMD chip has none. The Opteron’s transistor count of 2,400 million and die size of 2x 315 mm² have no equivalent data for the Intel part. Cache layouts are also distinct: Intel uses 64 KB L1 and 256 KB L2 per core with 6 MB shared L3, while AMD uses 768 KB L1, 2 MB L2 per module, and 8 MB L3 per die. The release dates are nearly a decade apart—March 2021 for Intel versus November 2012 for AMD—and the market segments differ (Desktop versus Server/Workstation). Production status shows Intel active and AMD end-of-life. The launch MSRP is $134 for the i3-10105T and $1392 for the Opteron 6386 SE.
