AMD Opteron 4334 vs Intel Core i3-N300 Comparison

The Verdict

The data presents a clear split between these two processors, each targeting a different era and use case. The AMD Opteron 4334, a server/workstation part from the Opteron 4000 series, and the Intel Core i3-N300, a modern mobile chip, are separated by over a decade of design philosophy.

Benchmark results indicate that the Intel Core i3-N300 dominates in most measured workloads, securing 4 wins out of 5 head-to-head comparisons. Its advantage is most pronounced in multi-core tests, where it outperforms the AMD Opteron 4334 by 50.5% in Cinebench R20 multi-core. However, the AMD Opteron 4334 posts a single, significant victory in Cinebench R23 multi-core, finishing 31.8% ahead of the Intel part. This single win suggests that the Opteron excels in a specific, sustained multi-threaded scenario, likely due to its design as a server processor with a higher thermal envelope.

The database percentile rankings place both chips in a similar tier, with the Opteron at the 33rd percentile and the i3-N300 at the 32nd percentile of all CPUs. Their average benchmark scores are nearly identical, with the AMD chip at 1155 and the Intel chip at 1135, a difference of less than 2%. The i3-N300 is the clear choice for anyone needing a low-power, versatile processor for everyday tasks, given its massive wins in Cinebench R20 and its single-core superiority. The AMD Opteron 4334, conversely, is the part to consider for legacy server workloads that scale well with its 8 MB of shared L3 cache and are optimized for its Piledriver architecture. Its win in Cinebench R23 multi-core shows that in certain sustained workloads, the older chip retains a measurable edge. For modern, general-purpose computing, the i3-N300 is the definitive winner based on the recorded data.

Where Each One Wins

The Intel Core i3-N300 demonstrates its strength in both single-core and multi-core performance in the majority of tests. Its most striking victory is in Cinebench R20 multi-core, where it scores 2849 against the Opteron's 1409, a 50.5% lead. This indicates that for contemporary software that leverages multiple cores efficiently, the i3-N300 is significantly faster. The Intel chip also wins in single-core tests, with a 50.6% lead in Cinebench R20 single-core (401 vs 198) and a 7.8% lead in Cinebench R23 single-core (513 vs 473). This suggests better per-thread performance, which is crucial for responsive everyday applications. The i3-N300 also wins the older Cinebench R15 multi-core test, scoring 416 to the Opteron's 338, an 18.7% difference.

The AMD Opteron 4334's single win is notable. In Cinebench R23 multi-core, it scores 3356, while the i3-N300 scores 2546. This 31.8% delta is the largest margin of victory for either side. This result suggests that the Opteron's architecture, with its 6 cores and 8 MB of shared L3 cache, can sustain a high workload in more recent Cinebench versions. The data shows that this is an isolated win, but it is substantial enough to indicate that the Opteron is not obsolete for all multi-threaded tasks. The pattern of wins suggests the i3-N300 is the better all-rounder, while the Opteron has a specific niche where it can still outperform.

Architecture Differences

The two processors are built on fundamentally different architectures, which explains their divergent benchmark results. The AMD Opteron 4334 uses the Piledriver architecture, codenamed Seoul, and is designed for the AMD Socket C32. It is fabricated on a 32 nm process node and has a transistor count of 1,200 million on a 315 mm² die. This is a legacy server design with a 95 TDP, reflecting its workstation heritage. Its cache configuration includes 288 KB of L1, 6 MB of L2, and a shared 8 MB L3 cache. It supports DDR3 memory and has 6 cores and 6 threads.

The Intel Core i3-N300 uses the Gracemont architecture, part of the Alder Lake-N generation, and is built for the Intel BGA 1264 socket. It is a modern mobile part on a 10 nm process node, fabricated by Intel. It has a drastically lower TDP of 7, highlighting its efficiency. The cache layout is different: it has 96 KB of L1 per core and 2 MB of L2 per module, with a shared 6 MB L3 cache. It supports both DDR4 and DDR5 memory in a single-channel configuration with a bandwidth of 38.4 GB/s. It also includes integrated graphics, specifically UHD Graphics 770, and has 8 cores and 8 threads. The i3-N300 supports PCIe Gen 3 with 9 lanes.

The production status also differs, with the Intel chip listed as active, while the Opteron's status is not specified. The release dates are separated by a decade, with the Opteron launching in December 2012 and the i3-N300 in January 2023. The base clock of the i3-N300 is listed as 100.00, which is an anomaly in the data, but its boost clock reaches 3.70 GHz, higher than the Opteron's 3.50 GHz boost. Neither processor supports ECC memory, and neither has an unlocked multiplier. These architectural differences, from process node to memory support, are the root cause of the performance gaps seen in the benchmarks.

Head-to-Head Benchmarks

The benchmark data reveals a consistent pattern, with the Intel Core i3-N300 asserting dominance in most tests, but the AMD Opteron 4334 securing a decisive win in one key area.

The most significant victory for the Intel chip is in Cinebench R20 multi-core, where it scores 2849. The AMD Opteron 4334 scores 1409 in the same test, meaning the Intel part is 50.5% faster. This is a massive gap, indicating that the i3-N300's 8 Gracemont cores handle this workload far more efficiently than the Opteron's 6 Piledriver cores. This result is the clearest evidence of the generational leap in performance.

The single-core tests also favor the Intel chip. In Cinebench R20 single-core, the i3-N300 scores 401, while the Opteron scores 198. This 50.6% delta is the largest margin of victory in any single-core test, showing a substantial per-thread advantage for the newer architecture. In Cinebench R23 single-core, the margin is smaller but still favors Intel, with scores of 513 and 473, a 7.8% lead.

In the older Cinebench R15 multi-core test, the Intel chip wins again, scoring 416 versus 338, an 18.7% advantage. This shows that even in legacy benchmarks, the i3-N300 is the stronger performer.

The one exception to this pattern is Cinebench R23 multi-core. Here, the AMD Opteron 4334 scores 3356, which is 31.8% higher than the Intel Core i3-N300's 2546. This is the only test where the Opteron wins, but the margin is the largest of any head-to-head comparison. This result is counterintuitive given the Intel chip's wins in the other multi-core tests, but the data is clear. The Opteron's design, with its larger 8 MB shared L3 cache and higher 95 TDP, appears to be better suited for this specific sustained workload. The difference in scores suggests that Cinebench R23 multi-core stresses the processors in a way that favors the AMD server part, possibly due to its power envelope allowing for sustained boost clocks. This single win, while not enough to change the overall verdict, does show that the Opteron retains a niche where it can outperform a much newer and more efficient mobile processor.
