AMD Opteron 4226 vs Intel Processor N100 Comparison

Head-to-Head Benchmarks

The recorded head-to-head data presents a split picture, with each processor claiming victory in different workload types. The most decisive win for the Intel Processor N100 comes in the Cinebench R23 single-core test, where it scores 910.5 against the AMD Opteron 4226’s 408. That is a 123.2% advantage, a massive gap that highlights the fundamental difference in per-thread performance between the two architectures. The Intel part’s Gracemont cores, despite being efficiency-focused, deliver far higher single-thread throughput than the older Bulldozer design.

In the Cinebench R15 multi-core test, the Intel Processor N100 again comes out ahead, scoring 401.5 versus the Opteron’s 291, a 38% lead. This is notable because the Opteron has six cores and six threads, while the Intel part has only four cores and four threads. The data suggests that the Intel chip’s higher clock speeds and more modern architecture more than compensate for its two-core deficit in this particular benchmark. The N100’s boost clock of 3.40 GHz, compared to the Opteron’s 3.10 GHz, likely contributes to this result.

However, the AMD Opteron 4226 strikes back in Cinebench R23 multi-core, scoring 2890 against the Intel’s 2559.5. That gives the AMD part an 11.4% advantage. This reversal is curious: the R15 multi-core test favors Intel, while the R23 multi-core test favors AMD. The difference may stem from how each benchmark scales with thread count and memory bandwidth. The Opteron’s dual-channel DDR3 memory support and six physical cores provide more raw throughput in a longer, more complex render workload, even though its individual cores are slower. The Intel N100’s single-channel memory bus, with a bandwidth of 38.4 GB/s, may become a bottleneck in the more demanding R23 test, while the Opteron’s 25.6 GB/s bandwidth, though lower, is paired with more cores to feed.

Looking at the broader benchmark averages, the two processors sit nearly identical in overall standing. The Intel Processor N100 has an average benchmark score of 1007, while the AMD Opteron 4226 averages 995. That is a difference of roughly 1.2%, well within the noise margin of the nearest rivals listed. The Intel part’s nearest rival, the Intel Core i5-10210Y, scores 1006, a delta of 0.1%, while the AMD part’s nearest rival, the Intel Core i7-2635QM, scores 995 with a delta of 0%. Both processors sit at the 27th percentile among all CPUs, meaning they land in the same performance tier according to the database’s aggregate metrics.

The head-to-head tally shows Intel winning two of the three direct comparisons, but the single AMD victory is substantial in the R23 multi-core test. The data implies that neither chip is a clean sweep winner; the choice depends entirely on which benchmark represents the intended workload. For short, lightly threaded tasks, the Intel N100 is clearly superior. For heavily threaded, sustained rendering workloads, the Opteron has the edge.

The Verdict

The recorded data points to a clear split based on workload type. The Intel Processor N100 wins decisively in single-thread performance, with a 123.2% lead in Cinebench R23 single-core, and also beats the Opteron in Cinebench R15 multi-core by 38%. This makes it the better choice for tasks that rely on per-core speed, such as everyday desktop applications, light productivity, or any software that is not heavily optimized for many threads. The N100’s 4 cores and 4 threads, combined with a boost clock of 3.40 GHz, deliver strong responsiveness in such scenarios.

The AMD Opteron 4226, on the other hand, wins in Cinebench R23 multi-core by 11.4%, which indicates it handles sustained, multi-threaded rendering workloads better. Its 6 cores and 6 threads, along with a larger shared L3 cache of 8 MB, allow it to maintain higher throughput in longer render passes. The Opteron also supports ECC memory, which the Intel part does not, making it a more suitable candidate for server or workstation environments where data integrity is critical. Its production status is end-of-life, however, while the Intel part is active, which may factor into long-term availability and support.

For a user prioritizing single-thread speed and modern features, the Intel Processor N100 is the data-backed pick. For a user running multi-threaded server workloads with ECC memory requirements, the AMD Opteron 4226 holds the advantage. Neither chip is a universal winner; the benchmark results show each excelling in distinct areas. The percentile ranking for both is identical at 27, reinforcing that they belong to the same overall performance class, but the specific benchmark wins reveal where each one has its strength.

Architecture Differences

The two processors come from entirely different design philosophies and eras. The Intel Processor N100 uses the Gracemont architecture, built on a 10 nm process at Intel’s own foundry. It is part of the Alder Lake-N generation, a lineup focused on efficiency and low power. The chip has 4 cores and 4 threads, with a base clock of 100.00 MHz (a nominal figure, likely representing a very low idle state) and a boost clock of 3.40 GHz. Its cache layout includes 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The memory support includes DDR4 and DDR5, but only via a single-channel bus, which caps bandwidth at 38.4 GB/s. It does not support ECC memory. The N100 also includes integrated UHD Graphics 730, making it a complete system-on-chip for mobile or compact devices.

The AMD Opteron 4226 uses the Bulldozer architecture, specifically the Valencia codename, built on a 32 nm process at GlobalFoundries. It is part of the Opteron 4000 series, designed for servers and workstations. This chip has 6 cores and 6 threads, with a base clock of 2.70 GHz and a boost clock of 3.10 GHz. Its cache is structured differently: 288 KB of L1, 6 MB of L2, and 8 MB of shared L3. The Opteron supports DDR3 memory via a dual-channel bus, providing 25.6 GB/s of bandwidth, and it does support ECC memory. It has no integrated graphics, as it is designed to pair with a discrete GPU or a server chipset. The transistor count is listed at 1,200 million, with a die size of 315 mm², reflecting the older, larger manufacturing process.

The process node difference is stark: 10 nm versus 32 nm. This explains much of the performance disparity, especially in single-thread workloads. The newer Intel process allows for higher clock speeds at far lower power, with the N100 having a TDP of 6 watts compared to the Opteron’s 95 watts. That is a 15.8x difference in thermal design power, though the Opteron’s higher TDP enables its six-core design to sustain multi-threaded loads. The memory channels also differ: single-channel on the Intel part versus dual-channel on the AMD part. This likely explains why the Opteron wins the R23 multi-core test despite its slower cores, as it can feed more data to more cores simultaneously.

The integrated graphics on the N100 is a significant architectural difference, as it allows the chip to operate without a discrete GPU. The Opteron lacks this entirely. The PCIe support also differs: the N100 has Gen 3 with 9 lanes, while the Opteron has Gen 2, with no lane count specified. For server use, the Opteron’s ECC support and dual-channel memory are more relevant, while the N100’s integrated graphics and low power make it suitable for compact, always-on devices.

Specification Differences

The two chips differ across nearly every specification field in the database. The Intel Processor N100 has 4 cores and 4 threads, while the AMD Opteron 4226 has 6 cores and 6 threads. The base clock of the N100 is listed as 100.00 MHz, which is an unusual figure, while the Opteron’s base clock is 2.70 GHz. The boost clocks are closer: 3.40 GHz for the N100 and 3.10 GHz for the Opteron. The TDP difference is enormous: 6 watts for the Intel part versus 95 watts for the AMD part.

The socket types are incompatible: Intel BGA 1264 for the N100, and AMD Socket C32 for the Opteron. The process nodes differ: 10 nm for Intel, 32 nm for AMD. The cache sizes are not directly comparable in layout: the N100 has 96 KB L1 per core, 2 MB shared L2, and 6 MB shared L3, while the Opteron has 288 KB L1, 6 MB L2, and 8 MB shared L3. Memory support differs: the N100 supports DDR4 and DDR5, the Opteron supports only DDR3. The memory bus is single-channel on the N100 and dual-channel on the Opteron. The memory bandwidth is 38.4 GB/s for the N100 and 25.6 GB/s for the Opteron. ECC memory support is false for the N100 and true for the Opteron.

The PCIe support is Gen 3 with 9 lanes on the N100, versus Gen 2 on the Opteron. The N100 has integrated UHD Graphics 730, while the Opteron has none. The market segments are mobile for the N100 and server/workstation for the Opteron. The production status is active for the N100 and end-of-life for the Opteron. The release dates are 2023 for the N100 and 2011 for the Opteron. The launch MSRP is $128 for the N100 and $125 for the Opteron. Neither chip has an unlocked multiplier. The transistor count and die size are listed only for the Opteron: 1,200 million and 315 mm², respectively.
