AMD Opteron 6212 vs Intel Core i5-4430 Comparison

AMD Opteron 6212 and Intel Core i5-4430 are two very different processors from different eras and market segments, yet their average benchmark scores land them within a hair of each other. The Opteron 6212, a server/workstation part built on AMD's Bulldozer architecture, posts an average benchmark score of 1162, while the desktop-oriented Core i5-4430 scores 1149. This near-parity in overall averages masks a fundamental split in how each chip performs, with the Intel part winning every single head-to-head Cinebench test in the data despite having half the physical cores. The data shows a consistent pattern: the Core i5-4430 is faster in every measured workload, but the Opteron 6212's relevance comes from its server-oriented feature set rather than raw speed.

Where Each One Wins

The benchmark results leave little room for ambiguity: the Intel Core i5-4430 wins all five recorded head-to-head tests. In Cinebench R15 multi-core, the i5-4430 scores 400 against the Opteron's 340, a 15% deficit for the AMD chip. That margin holds steady across every other test — R20 multi-core shows 1669 versus 1418 (also -15%), and R23 multi-core shows 3974 versus 3377 (-15%). The single-core tests tell the same story: R20 single-core has the i5-4430 at 235 versus 199 (-15.3%), and R23 single-core has it at 561 versus 476 (-15.2%). The Opteron 6212 records zero wins in the head-to-head dataset.

The Opteron 6212's wins are not in benchmark scores but in platform capabilities. It supports quad-channel DDR3 memory with 51.2 GB/s of bandwidth, while the i5-4430 is limited to dual-channel. The Opteron also supports ECC memory, which the Core i5-4430 does not. For workloads that benefit from memory bandwidth and error-correcting memory — think long-running server processes or data integrity-sensitive tasks — the Opteron 6212 has a structural advantage that Cinebench scores do not capture. The i5-4430 counters with PCIe Gen 3 support versus the Opteron's Gen 2, plus integrated Intel HD 4600 graphics that the Opteron lacks entirely. In purely computational terms, the i5-4430 is the clear winner; in platform flexibility for server duty, the Opteron 6212 holds its ground.

A: Yes. The Opteron 6212 supports ECC memory and runs quad-channel DDR3 with 51.2 GB/s of bandwidth. The Core i5-4430 does not support ECC and is limited to dual-channel memory.

Q: Which processor has integrated graphics?

A: Only the Intel Core i5-4430 includes integrated graphics (Intel HD 4600). The AMD Opteron 6212 has no integrated graphics, which is typical for a server/workstation processor.

Q: How do their average benchmark scores compare?

A: The Opteron 6212 has an average benchmark score of 1162, while the Core i5-4430 averages 1149. They are separated by roughly 1%, and both sit at the 33rd percentile of all CPUs.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the consistency of the margin. Across five different Cinebench tests, the Core i5-4430 beats the Opteron 6212 by between 15% and 15.3% every single time. This is not a case where one chip wins lightly in one test and loses in another — the i5-4430 dominates uniformly.

The largest numeric gaps appear in the multi-core tests. In Cinebench R23 multi-core, the i5-4430 scores 3974 versus the Opteron's 3377, a difference of 597 points. In R20 multi-core, the gap is 251 points (1669 vs 1418). The R15 multi-core test shows a smaller absolute gap of 60 points (400 vs 340), but the percentage deficit remains exactly 15%. Single-core tests follow the same pattern: R23 single-core shows an 85-point gap (561 vs 476), and R20 single-core shows a 36-point gap (235 vs 199).

The closest contest in percentage terms is R20 single-core at -15.3%, which is also the smallest absolute gap. This suggests the Opteron 6212's deficiency is not limited to multi-threaded scaling — its single-thread performance per clock is also behind. The Opteron's boost clock of 3.20 GHz matches the i5-4430's boost clock of 3.20 GHz, yet the i5-4430 still pulls ahead by 15% in single-core workloads. That points to architectural efficiency differences rather than clock speed. The i5-4430's Haswell design simply executes more work per cycle than the Bulldozer-based Opteron.

Specification Differences

The two processors differ substantially in their basic specifications. The Opteron 6212 has 8 cores and 8 threads, while the Core i5-4430 has 4 cores and 4 threads. Base clocks differ: the Opteron runs at 2.60 GHz, the i5-4430 at 3.00 GHz. Both boost to 3.20 GHz. Power draw favors the Intel part significantly: the Opteron 6212 has a 115W TDP versus the i5-4430's 84W.

Memory architecture is a major dividing line. The Opteron 6212 supports quad-channel DDR3 with a rated bandwidth of 51.2 GB/s and ECC memory support. The Core i5-4430 uses dual-channel DDR3 with no ECC support and no listed bandwidth figure. PCIe generation also differs: the Opteron 6212 is Gen 2, while the i5-4430 is Gen 3. The i5-4430 includes Intel HD 4600 integrated graphics; the Opteron 6212 has no integrated graphics at all.

Sockets and platforms are incompatible. The Opteron 6212 uses AMD Socket G34, a server platform, while the i5-4430 uses Intel Socket 1150, a mainstream desktop socket. The Opteron 6212's part number is OS6212WKT8GGU, and the i5-4430's is SR14G. Neither processor has an unlocked multiplier. The Opteron 6212 was released in November 2011 with a launch MSRP of $266; the Core i5-4430 came later in June 2013.

Architecture Differences

The architectural divide here is stark. The Opteron 6212 is built on AMD's Bulldozer architecture, codenamed Interlagos, and belongs to the Opteron 6000 series. It uses a 32 nm process from GlobalFoundries, with 2,400 million transistors spread across two 315 mm² dies. The Intel Core i5-4430 uses the Haswell architecture, also its codename, on a 22 nm process from Intel, with 1,400 million transistors on a single 177 mm² die.

Cache layouts reflect the different design philosophies. The Opteron 6212 has 768 KB of L1 cache, 2 MB of L2 cache per module, and 8 MB of L3 cache per die. The Core i5-4430 has 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. The Opteron's cache is organized around its module-based Bulldozer design, while the i5-4430 uses a more conventional per-core layout.

The Opteron 6212's large, dual-die design with 2,400 million transistors on 32 nm is characteristic of AMD's server push with Bulldozer. The i5-4430's smaller, denser 22 nm design with 1,400 million transistors shows Intel's process advantage at the time. The Opteron's ECC support and quad-channel memory controller are server-oriented features, while the i5-4430's integrated HD 4600 graphics and PCIe Gen 3 support target desktop users. The Opteron 6212 is marked as end-of-life, and its production status for the i5-4430 is not listed in the data.

The Verdict

The benchmark data is unambiguous: the Intel Core i5-4430 outperforms the AMD Opteron 6212 in every recorded test. A 15% deficit across all five Cinebench tests, whether multi-core or single-core, means the i5-4430 is simply the faster processor in these workloads. The fact that the i5-4430 achieves this with half the cores (4 vs 8) and 31 fewer watts of TDP (84W vs 115W) underscores the efficiency gap between Haswell and Bulldozer. The i5-4430 also brings integrated graphics, PCIe Gen 3, and a higher base clock to the table.

However, the Opteron 6212 is not without purpose. Its quad-channel memory controller with 51.2 GB/s bandwidth and ECC support are features the i5-4430 simply does not offer. For someone building a system that requires error-correcting memory or maximum memory bandwidth for server-style workloads, the Opteron 6212 is the only choice between these two. Its 8 cores, while slower per core, could still be preferable in scenarios where thread count matters more than per-thread speed — though the benchmark data shows the 4-core i5-4430 winning multi-core tests anyway.

The choice comes down to platform needs versus raw CPU performance. If you need ECC memory, quad-channel bandwidth, and a server socket, the Opteron 6212 is your part. If you want faster Cinebench scores, lower power draw, integrated graphics, and a desktop platform, the Core i5-4430 wins outright. The i5-4430's clean sweep of the head-to-head benchmarks makes it the better processor for general computing, while the Opteron 6212's value lies entirely in its enterprise-oriented feature set. Both chips sit at the 33rd percentile of all CPUs, so neither is a performance leader by modern standards — but within this pairing, the i5-4430 is the one to pick for speed.
