CPU Comparison

The AMD Opteron 4334 and Intel Core i5-4430 are both older processors that now land in the same performance tier, with average benchmark scores of 1155 and 1149 respectively. The data shows a consistent pattern: the Intel part wins every single head-to-head benchmark, yet the overall scores remain remarkably close, separated by only 0.5 percent. This is a matchup where architectural philosophy matters more than raw performance, as the Opteron brings six cores and a server pedigree while the Core i5 counters with four newer, more efficient cores.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the Intel Core i5-4430 wins all five recorded Cinebench comparisons. In the multi-core tests, the Intel part leads by a narrow but consistent margin. In Cinebench R15 multi-core, the Core i5 scores 400 against the Opteron's 338, a 15.5 percent advantage. The pattern repeats in Cinebench R20 multi-core, where Intel posts 1669 versus AMD's 1409, a 15.6 percent gap. The Cinebench R23 multi-core test shows the same story: Intel scores 3974, AMD scores 3356, again a 15.6 percent difference.

Single-core performance tells nearly the identical story. In Cinebench R20 single-core, the Core i5-4430 scores 235 while the Opteron 4334 manages 198, a 15.7 percent deficit. The Cinebench R23 single-core test shows 561 for Intel versus 473 for AMD, also a 15.7 percent gap. The consistency of these deltas, hovering between 15.5 and 15.7 percent across every test, suggests a fundamental per-clock efficiency advantage for the Intel architecture rather than any workload-specific quirk.

The Opteron's best showing is in the average benchmark score category, where it edges ahead by 0.5 percent (1155 versus 1149). This is a statistical tie, but it does indicate that the AMD chip's extra two cores help close the gap in some aggregate metrics. The nearest-rival data also places both processors in the same performance band: the Opteron's closest rival is the AMD Ryzen Embedded R2312 at 1156 (a 0.1 percent difference), while the Core i5's closest rival is the Intel Core i7-3612QE at 1147 (a 0.2 percent difference). Neither processor is an outlier; both sit near the 33rd percentile of all CPUs.

The Verdict

The data points to a clear winner for most workloads: the Intel Core i5-4430. It outperforms the AMD Opteron 4334 in every recorded benchmark by roughly 15.6 percent, whether the workload is single-threaded or multi-threaded. The Core i5 also achieves this with a lower TDP (84 watts versus 95 watts), which makes it the more power-efficient choice on paper. For any application that relies on Cinebench-style rendering or general CPU throughput, the Intel part is the better option.

However, the Opteron 4334 is not without justification. Its higher core count (six versus four) and server-class positioning suggest it may handle certain multi-threaded server workloads differently, even if the Cinebench numbers do not show an advantage. The average benchmark score of 1155 versus 1149 indicates that in some aggregate measures, the Opteron is effectively on par. A buyer running software that scales well beyond four cores and that benefits from the Opteron's specific cache topology might find the AMD part acceptable, especially given its 33rd percentile ranking matches the Core i5 exactly.

The realistic verdict: the Core i5-4430 is the stronger processor for most users. It wins every benchmark, consumes less power, and offers integrated graphics. The Opteron 4334 is only viable if the platform requires a socket C32 motherboard or if the six-core configuration is specifically needed for a legacy server environment where the Core i5's desktop socket is incompatible.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Opteron 4334 uses the Piledriver architecture under the codename "Seoul," built on a 32 nm process node. It packs 1,200 million transistors into a 315 mm² die. The Intel Core i5-4430 uses the Haswell architecture (also codenamed Haswell), built on a smaller 22 nm process with 1,400 million transistors in a much smaller 177 mm² die. The smaller process node and higher transistor count explain why Intel achieves better per-core performance despite having fewer cores.

Cache configurations differ significantly. The Opteron 4334 has 288 KB of L1 cache, 6 MB of L2 cache, and 8 MB of shared L3 cache. The Core i5-4430 specifies its cache per core: 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. With four cores, the Core i5's total L1 is 256 KB and total L2 is 1 MB. The Opteron's larger L2 and L3 allocations reflect its server heritage, where larger working sets are common, but the benchmark data suggests this does not translate into a performance win.

The Opteron 4334 is a server/workstation part, released in December 2012, while the Core i5-4430 is a desktop part released in June 2013. The Opteron uses AMD Socket C32, while the Core i5 uses Intel Socket 1150. Neither processor has ECC memory support, and both support DDR3 memory. The Core i5 includes integrated graphics (Intel HD 4600) and PCIe Gen 3 support, while the Opteron lists no integrated graphics and no PCIe specification. The Opteron's multiplier is locked, and the Core i5's multiplier is also locked.

Specification Differences

The most direct specification differences are as follows:

• Cores and threads: The Opteron 4334 has 6 cores and 6 threads; the Core i5-4430 has 4 cores and 4 threads.
• Base clock: The Opteron runs at 3.10 GHz; the Core i5 runs at 3.00 GHz.
• Boost clock: The Opteron boosts to 3.50 GHz; the Core i5 boosts to 3.20 GHz.
• TDP: The Opteron is rated at 95 watts; the Core i5 is rated at 84 watts.
• Process node: The Opteron uses 32 nm; the Core i5 uses 22 nm.
• Transistors: The Opteron has 1,200 million; the Core i5 has 1,400 million.
• Die size: The Opteron measures 315 mm²; the Core i5 measures 177 mm².
• L3 cache: The Opteron has 8 MB shared; the Core i5 has 6 MB shared.
• Socket: The Opteron uses AMD Socket C32; the Core i5 uses Intel Socket 1150.
• Integrated graphics: The Opteron has none; the Core i5 includes Intel HD 4600.
• PCIe: The Opteron lists none; the Core i5 lists Gen 3.
• Market segment: The Opteron is Server/Workstation; the Core i5 is Desktop.
• Foundry: The Opteron has no listed foundry; the Core i5 is fabricated by Intel.
• Part number: The Opteron is OS4334WLU6KHK; the Core i5 is SR14G.

Note that the Opteron has a higher base clock (3.10 GHz versus 3.00 GHz) and a higher boost clock (3.50 GHz versus 3.20 GHz), yet it still loses every benchmark. This underscores that clock speed alone does not determine performance; the Intel architecture's efficiency per clock is the deciding factor.
