AMD Opteron 4386 vs Intel Core i3-4130 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core i3-4130 across all five Cinebench comparisons. The margins are consistent, ranging from 1.8% to 2.4%, which indicates a stable performance advantage rather than a workload-specific anomaly. In the Cinebench R15 multi-core test, the Intel part scores 285 against the AMD Opteron 4386's 280, a delta of 1.8%. That same 1.8% delta repeats in Cinebench R20 multi-core, with scores of 1189 and 1168 respectively.

Single-core results follow the same pattern with slightly larger gaps. The Intel Core i3-4130 posts 168 points in Cinebench R20 single-core, while the Opteron 4386 manages 164, giving Intel a 2.4% lead. The Cinebench R23 single-core test shows 400 versus 392, a 2% difference. The multi-core R23 result is 2833 for Intel and 2782 for AMD, again a 1.8% margin.

What stands out is the consistency of the multi-core deltas. All three multi-core tests land at exactly 1.8%, suggesting the performance ratio between these two processors is highly stable under threaded loads. The single-core margins are slightly wider, which aligns with the architectural differences discussed later. The Intel part wins all five head-to-head matchups, and the average benchmark score confirms the overall picture: 975 for the i3-4130 versus 957 for the Opteron 4386, a gap that places them in the same percentile tier at 26% but with the Intel chip ahead in every measured test.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i3-4130 uses the Haswell architecture on a 22 nm process node, built by Intel with 1,400 million transistors on a 177 mm² die. The AMD Opteron 4386 uses the Piledriver architecture, codenamed Seoul, on a 32 nm process with 1,200 million transistors and a much larger 315 mm² die. The process node difference is significant: 22 nm versus 32 nm gives Intel a density and efficiency advantage that shows up in the TDP figures.

Core counts diverge sharply. The i3-4130 has 2 physical cores with 4 threads via Hyper-Threading, while the Opteron 4386 has 8 physical cores with 8 threads, no simultaneous multithreading. This is a classic trade-off: the Opteron has four times the physical core count, yet it still trails in every benchmark. The Intel chip compensates with higher per-core efficiency and a 3.40 GHz base clock versus the Opteron's 3.10 GHz base and 3.80 GHz boost.

Cache hierarchies also differ substantially. The Intel part has 64 KB L1 per core, 256 KB L2 per core, and 3 MB shared L3. The AMD part lists 384 KB L1 total, 8 MB L2 total, and 8 MB shared L3. The Opteron's larger total cache is expected given its eight cores, but the per-core allocation is thinner. Die size reflects this: 315 mm² for AMD versus 177 mm² for Intel, even though AMD uses fewer transistors.

Memory support is DDR3 for both, but the Intel chip uses a dual-channel memory bus, while the database does not record a memory bus width for the Opteron. Intel's PCIe interface is Gen 3; AMD's is not recorded. The i3-4130 includes integrated graphics, the Intel HD 4400, whereas the Opteron 4386 has no integrated graphics at all. The market segments differ: the i3 is a desktop part, the Opteron is a server/workstation part. The Opteron also carries a 95 W TDP versus 54 W for the i3, a 41 W difference that reflects the higher core count and older process node.

Where Each One Wins

The Intel Core i3-4130 wins every recorded benchmark, so the use-case split is straightforward from the data. The i3's single-core advantage of 2.4% in Cinebench R20 and 2% in R23 makes it the better choice for lightly threaded applications, such as older games, desktop productivity, or any workload that depends on one or two strong cores. The multi-core wins, though smaller at 1.8%, still hold across R15, R20, and R23, meaning even in fully threaded scenarios the i3-4130 comes out ahead despite having only 2 physical cores.

The AMD Opteron 4386 does not win any recorded test. Its 8 cores do not translate into a benchmark victory, and the data shows it trailing by the same 1.8% margin in all multi-core tests. However, the Opteron's architecture is not without merit in contexts the benchmarks do not capture. Its socket, AMD Socket C32, and server/workstation market segment suggest it is designed for multi-socket or long-life server deployments, where raw core count and memory capacity matter more than per-core speed. The database does not record memory bandwidth or PCIe support for the Opteron, so those aspects cannot be quantified here.

For a desktop user, the i3-4130 is the clear winner in every measured metric. For a server environment where the Opteron's platform features, such as its socket and form factor, are required, the data shows a slight performance deficit but does not rule out the part entirely. The percentile ranking puts both at 26% of all CPUs, indicating they sit in the same performance tier relative to the broader market.

Specification Differences

The two processors differ in nearly every major specification category. Core and thread counts differ completely: 2 cores and 4 threads for Intel versus 8 cores and 8 threads for AMD. Base clocks are close, 3.40 GHz for Intel and 3.10 GHz for AMD, but the Opteron adds a 3.80 GHz boost clock, which the i3 does not have. TDP is nearly double for the AMD part: 95 W versus 54 W.

Sockets are incompatible: Intel Socket 1150 for the i3-4130, AMD Socket C32 for the Opteron 4386. Architecture and codename differ: Haswell versus Piledriver, with the Intel codename also Haswell and the AMD codename Seoul. Process node is 22 nm for Intel and 32 nm for AMD. Transistor counts are 1,400 million for Intel and 1,200 million for AMD, while die sizes are 177 mm² and 315 mm² respectively.

Cache configurations are structured differently. The Intel chip has per-core L1 and L2 (64 KB and 256 KB per core), plus 3 MB shared L3. The AMD chip lists total L1 at 384 KB and total L2 at 8 MB, with 8 MB shared L3. Memory support is DDR3 for both, but Intel records a dual-channel bus, while AMD does not record a bus width. PCIe generation is Gen 3 for Intel, not recorded for AMD. Integrated graphics exist only on the Intel part. Market segments differ: Desktop for Intel, Server/Workstation for AMD. Release dates are about nine months apart: the i3-4130 launched in 2013, the Opteron 4386 in 2012. Part numbers also differ, as do the series and generation fields, with the Opteron carrying the Opteron 4000 series label.

The Verdict

The data is unambiguous: the Intel Core i3-4130 outperforms the AMD Opteron 4386 in every recorded benchmark. The margins are modest, between 1.8% and 2.4%, but they are consistent across all five tests. The i3-4130 achieves this with half the physical cores, a lower TDP, and a smaller die, which points to substantially better per-core efficiency.

For desktop users, the i3-4130 is the superior choice based on the recorded data. It wins single-core tests by a slightly larger margin, which matters for everyday applications and games that rely on one or two threads. Its integrated graphics also remove the need for a separate GPU in basic systems, a feature the Opteron lacks entirely.

For server or workstation deployments, the Opteron 4386 is the only one of the two that fits that market segment, and its Socket C32 platform may be required for specific server boards. However, the data shows it is slower in every measured test. The 8-core Opteron cannot convert its core advantage into a performance win, and its higher 95 W TDP makes it less efficient. The i3-4130's 54 W TDP and smaller process node reinforce its efficiency lead.

The percentile rankings place both at 26% of all CPUs, so neither is a high-performance part by modern standards. But within this head-to-head, the Intel Core i3-4130 is the faster processor, and the benchmark database records no scenario where the Opteron 4386 comes out ahead. Anyone choosing between these two should pick based on platform requirements, not performance, because the performance data consistently favors Intel.
