AMD Opteron 4376 HE vs Intel Processor N95 Comparison

Head-to-Head Benchmarks

The benchmark data reveals a fascinating split between these two processors, with each claiming victories in different workload categories. The Intel Processor N95 emerges victorious in three of the four head-to-head comparisons, while the AMD Opteron 4376 HE secures one decisive win that flips the overall multi-core narrative.

Starting with the most lopsided result, the Cinebench R15 single-core test shows the Intel Processor N95 scoring 151 against the Opteron's 52, a staggering 190.4% advantage. This gap underscores the fundamental difference in single-thread capability between the two designs. The N95's modern architecture delivers nearly three times the performance in this workload, making it the clear choice for latency-sensitive, lightly threaded tasks.

The Cinebench R23 single-core test tells a similar story, though with a smaller margin. Here the Intel part scores 914 versus the AMD's 518, a 76.4% lead. While not as dramatic as the R15 result, this still represents a substantial advantage in single-threaded performance that will manifest in everyday responsiveness and applications that cannot scale across multiple cores.

In multi-core workloads, the results are more nuanced. The Cinebench R15 multi-core test favors the Intel Processor N95 with a score of 445 against 369, a 20.6% win. This is notable because the Opteron has twice the core count, yet still trails in this particular benchmark. The Intel part's efficiency per core more than compensates for its numerical disadvantage in core count.

However, the Cinebench R23 multi-core test flips the script. Here the AMD Opteron 4376 HE scores 3670 against the Intel's 2769, giving the AMD part a 24.6% advantage. This suggests that the R23 test is more effective at leveraging the Opteron's eight cores, and the sustained multi-threaded workload plays to the AMD processor's strengths. The delta of 901 points represents the largest absolute difference in any benchmark between the two chips.

Looking at the aggregate data, the Intel Processor N95 holds an average benchmark score of 1070, while the AMD Opteron 4376 HE sits at 1061. Both processors land at the 29th percentile among all CPUs in the database, placing them in similar overall performance tiers despite their architectural differences. The Intel part's nearest rivals include the Intel Core i7-2820QM at 1069 (0.1% behind), the AMD Opteron 3380 at 1071 (0.1% ahead), and the AMD Athlon X4 880K at 1071 (0.1% ahead). The AMD Opteron's closest competitors are the Intel Core i3-4360 at 1061 (0% difference), the Intel Core i5-4570TE at 1062 (0.1% behind), and the AMD FX-8320E at 1059 (0.2% ahead).

Architecture Differences

The two processors represent fundamentally different design philosophies separated by more than a decade of silicon evolution. The Intel Processor N95 uses the Gracemont architecture, built on a 10 nm process node at Intel's foundries. This is Intel's efficient-core design, part of the Alder Lake-N generation, and it prioritizes power efficiency alongside reasonable performance. The chip packs 4 cores with 4 threads, running at a base clock of 100.00 MHz (which appears to be a minimum idle state) with a boost clock of 3.40 GHz. The thermal design power is just 15 watts, making it suitable for fanless or low-power mobile implementations.

The AMD Opteron 4376 HE, by contrast, uses the Piledriver architecture under the Seoul codename, manufactured on a 32 nm process. This is a server-class part from the Opteron 4000 series, featuring 8 cores and 8 threads. Its base clock is 2.60 GHz with a boost to 3.60 GHz. The thermal design power is 65 watts, more than four times that of the Intel part, reflecting the older process technology and higher operating voltages. The Opteron integrates 1,200 million transistors across a 315 mm² die, a substantial silicon footprint by modern standards.

Cache hierarchies differ markedly between the two. The Intel Processor N95 offers 96 KB of L1 cache per core, 2 MB of shared L2 cache, and 6 MB of shared L3 cache. The AMD Opteron provides 384 KB of L1 cache total, 8 MB of L2 cache, and 8 MB of shared L3 cache. While the Opteron has more total cache, the Intel part's per-core L1 allocation is significantly higher, which helps explain its single-thread performance advantage.

Memory support diverges completely. The Intel Processor N95 supports both DDR4 and DDR5 memory through a single-channel interface, delivering 38.4 GB/s of memory bandwidth. The AMD Opteron 4376 HE is limited to DDR3 memory, and the database records no memory bandwidth figure for it. The Intel part also features PCIe Gen 3 with 9 lanes (CPU only) and integrated UHD Graphics 710, while the Opteron has no integrated graphics and no PCIe data recorded.

The Opteron does not support ECC memory according to the database, despite its server positioning, and neither processor has an unlocked multiplier. The Intel part remains in active production with a release date of January 2023, while the Opteron's production status is not recorded, with a release date of December 2012. The Opteron carries part number OS4376OFU8KHK.

Where Each One Wins

The benchmark results point to distinct use-case advantages for each processor. The Intel Processor N95 dominates in any scenario where single-threaded performance matters. Its 190.4% lead in Cinebench R15 single-core and 76.4% lead in R23 single-core make it the obvious choice for desktop responsiveness, web browsing, office productivity, and applications that rely on a few fast cores rather than many slower ones. The 15 watt TDP also makes it suitable for compact, passively cooled systems where power draw and heat generation are primary concerns.

The AMD Opteron 4376 HE claims its sole victory in the Cinebench R23 multi-core test, where it outperforms the Intel part by 24.6%. This indicates that in sustained, heavily threaded workloads, the eight-core Opteron can leverage its additional cores to pull ahead. This makes it relevant for server-style workloads, batch processing, rendering tasks that scale well across cores, and any application that can keep all eight threads busy for extended periods. The 65 watt TDP, while higher than the Intel part, is still considered low-power for a server processor of its era, as indicated by the "HE" (high efficiency) designation.

However, the R15 multi-core result complicates this picture. The Intel Processor N95 wins that test by 20.6% despite having half the cores. This suggests that the R15 benchmark is less effective at utilizing the Opteron's additional cores, or that the Intel part's superior per-core performance carries it through. The discrepancy between R15 and R23 multi-core results indicates that the Opteron's advantage only materializes in the more demanding, longer-running R23 workload.

In terms of overall average benchmark scores, the two are nearly identical, with the Intel part at 1070 and the AMD at 1061, a difference of less than 1%. Both sit at the 29th percentile among all CPUs, meaning they occupy similar positions in the overall performance hierarchy. The choice between them therefore depends less on raw aggregate performance and more on the specific workload patterns expected.

The Verdict

The data supports a clear recommendation for most users: the Intel Processor N95 offers superior performance in the majority of tested workloads. It wins three of four head-to-head benchmarks, including both single-core tests and the R15 multi-core test, while consuming only 15 watts of power. Its modern Gracemont architecture on a 10 nm process delivers exceptional efficiency, and its support for DDR4 and DDR5 memory makes it a more flexible platform choice.

The AMD Opteron 4376 HE should be selected only for specific workloads that can fully exploit its eight cores in sustained, demanding multi-threaded scenarios, as evidenced by its R23 multi-core victory. Its 65 watt TDP and older 32 nm Piledriver architecture make it less efficient, and its DDR3 memory support is a significant limitation in modern systems. However, for applications that scale perfectly across eight threads and run for extended periods, the R23 result shows it can outpace the Intel part by 24.6%.

For general-purpose computing, mobile deployments, or systems where power consumption matters, the Intel Processor N95 is the clear choice from the recorded data. For dedicated multi-threaded server workloads that resemble the R23 test, the AMD Opteron 4376 HE retains a measurable advantage. The near-identical average benchmark scores (1070 versus 1061) confirm that these are closely matched in overall capability, with the deciding factor being the specific workload profile.
