AMD Opteron 4332 HE vs Intel Core i3-1115GRE Comparison

Head-to-Head Benchmarks

The benchmark data is unequivocal: the Intel Core i3-1115GRE wins every recorded head-to-head test against the AMD Opteron 4332 HE. Out of five Cinebench comparisons, the Intel part takes all five, with margins ranging from 14.5% to 15.2%. That is a clean sweep, and the consistency of the margin is notable.

Starting with the oldest test in the database, Cinebench R15 multi-core, the i3-1115GRE scores 392 against the Opteron's 335. That is a 14.5% advantage. The R20 multi-core test shows a nearly identical gap: Intel scores 1637 versus AMD's 1396, a 14.7% lead. The R23 multi-core result repeats the pattern, 3899 for Intel versus 3324 for AMD, again a 14.7% margin. The Intel chip is consistently about 15% faster regardless of the workload generation.

Single-core results are even more decisive in relative terms. In Cinebench R20 single-core, the Intel part scores 231 against AMD's 196, a 15.2% lead. In R23 single-core, Intel scores 550 versus 469, a 14.7% edge. The fact that the single-core margin is roughly the same as the multi-core margin is telling: the Intel chip wins per-thread performance without needing extra cores, and it does not lose that advantage when all cores are loaded.

The Opteron does have a core-count advantage, six cores versus two, and six threads versus four. That should theoretically help in heavily threaded workloads. The data shows otherwise. The i3-1115GRE's newer architecture and higher boost clock (3.90 GHz versus 3.70 GHz) overwhelm the AMD part's extra physical cores. The Opteron's 6 MB of L2 cache and 8 MB of shared L3 do not rescue it either.

The average benchmark score in the database puts the Intel chip at 1127, which is 1.5% lower than the AMD's 1144. That seems contradictory given the head-to-head results, but the averages include different test sets and the Opteron's nearest rivals are different from the i3's. The Opteron's nearest rival, the Intel Core i7-2600S, has an average score of 1146, a delta of only -0.2%. The i3-1115GRE's nearest rival, the Intel Core i5-3330S, scores 1128, a delta of -0.1%. These are close, but the head-to-head Cinebench numbers are the more direct comparison.

Where Each One Wins

The Intel Core i3-1115GRE wins every benchmark where both processors recorded scores. That includes all multi-core and single-core tests in the database. There is no recorded workload in which the AMD Opteron 4332 HE leads. The Intel part's single-core advantage of 14.7% to 15.2% translates directly to faster response in lightly threaded applications, and its multi-core lead of 14.5% to 14.7% means it also handles all-core workloads better despite having fewer cores.

The AMD Opteron 4332 HE wins only in areas not measured by these benchmarks. It has more physical cores, six versus two, and more threads, six versus four. The database has no multi-threaded test beyond Cinebench, but the core count could help in code that scales almost perfectly across cores. That said, the recorded Cinebench multi-core results show Intel winning even in a multi-threaded scenario, so the Opteron's core advantage does not translate into a measurable win in the available data.

The Opteron also supports DDR3 memory, while the Intel supports DDR4 and LPDDR4X. The Intel memory bus is dual-channel. Neither memory bandwidth figure is in the database, so no quantitative comparison is possible. The Intel part has integrated graphics, UHD Graphics G4 48EU, while the AMD has no integrated graphics listed. For a mobile system, that is a practical difference.

Architecture Differences

The two processors come from entirely different eras and design philosophies. The AMD Opteron 4332 HE is a server and workstation part from the Opteron 4000 series, based on the Piledriver architecture with the codename Seoul. It was released in early December 2012. The Intel Core i3-1115GRE is a mobile processor from the Tiger Lake-U family, using the Tiger Lake architecture with Willow Cove cores. It was released in September 2020. That is a gap of nearly eight years in design.

The process nodes differ significantly. The AMD part uses a 32 nm process, while the Intel uses a 10 nm process. The die sizes reflect that: the Opteron's die is 315 square millimeters, and the Intel's is 144 square millimeters. The Opteron has 1,200 million transistors, while the Intel's transistor count is not listed in the database.

The cache structures are also different. The Opteron has a total L1 cache of 288 KB, a 6 MB L2, and an 8 MB shared L3. The Intel has an 80 KB L1 per core, a 1.25 MB L2 per core, and a 6 MB shared L3. With two cores, the Intel's L1 totals 160 KB and its L2 totals 2.5 MB, so the AMD has more L1 and L2 cache in total, but the Intel has a larger L3 relative to its core count.

Memory support is split by generation: the Opteron uses DDR3, and the Intel uses DDR4 and LPDDR4X. The Intel supports ECC memory, and the database lists the Opteron as not having ECC support. The Intel has a PCI Express Gen 4 interface with 4 CPU-only lanes, while the Opteron has no PCIe information listed.

The Intel has a much lower TDP at 15 watts versus the Opteron's 65 watts. That is a 4.3x difference, and it is a major factor in the i3-1115GRE being a mobile part. The Opteron is a server/workstation part with a socketed design, while the Intel is a BGA 1449 mobile chip. The Opteron's base clock is 3.00 GHz and its boost is 3.70 GHz, while the Intel's base clock is lower at 2.20 GHz but its boost is higher at 3.90 GHz.

The Verdict

The benchmark data is clear and unambiguous. The Intel Core i3-1115GRE is the better processor for all recorded workloads. It wins every Cinebench test, both single-core and multi-core, with margins between 14.5% and 15.2%. That advantage holds even though the AMD has three times as many physical cores and a higher base clock.

The AMD Opteron 4332 HE does not win a single benchmark in the database. Its higher core count is its only theoretical advantage, but the actual test results show the Intel part outperforming it in all-core workloads. The Opteron's 65-watt TDP is also a significant drawback for any system where power consumption is a concern.

For anyone choosing between these two based on the database results, the answer is the Intel Core i3-1115GRE. It is faster in both single-threaded and multi-threaded Cinebench tests, has a higher boost clock, supports newer memory, includes integrated graphics, and uses far less power. The AMD part is from an older generation, uses more power, and loses every measurement.

The Intel also has a clear edge in modern features. It uses a 10 nm process, supports PCIe Gen 4, has ECC memory support, and is an active production part. The AMD is a 32 nm part with a server socket, and its production status is not listed as active.

The only reason to consider the AMD would be if the system requires the Opteron 4000 series socket, but that is a compatibility question, not a performance one. Based on the benchmark data, the Intel Core i3-1115GRE is the superior processor in this comparison.
