AMD Opteron 6344 vs Intel Core i5-4670S Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent and uniform advantage for the AMD Opteron 6344 across every Cinebench iteration in the head-to-head comparison. In Cinebench R15 multi-core, the Opteron scores 519 against the Core i5-4670S’s 448, a 13.7% deficit for the Intel part. The single-core R15 test repeats the exact same margin: 73 versus 63, again 13.7%. This pattern of identical deltas across different workloads suggests a fixed performance ratio rather than workload-specific scaling.

Cinebench R20 multi-core continues the trend, with the Opteron at 2166 and the i5-4670S at 1870, a 13.7% difference. The single-core R20 result is 305 versus 263, which computes to a 13.8% gap, the largest margin recorded in any test. Cinebench R23 shows the smallest delta in the set, 13.6% in multi-core: the Opteron reaches 5158 while the i5-4670S manages 4454. The R23 single-core test closes at 728 versus 628, another 13.7% split. The consistency is striking: every delta falls between 13.6% and 13.8%, meaning the AMD part leads by a near-constant proportion regardless of render complexity or core count utilization.

The Intel processor records zero wins across the six head-to-head benchmarks. The Opteron wins all six. This is not a case of one chip being better in some scenarios and worse in others; the AMD Opteron 6344 is faster in every recorded measurement. The average benchmark score tells a similar story, though with a smaller gap: the i5-4670S averages 1526 across its full benchmark suite, while the Opteron averages 1492. Those averages include different benchmark sets, so the head-to-head Cinebench results are the more reliable direct comparison.

Percentile placement offers context. Both processors sit at the 38th percentile among all CPUs in the database. That parity in percentile, despite the Opteron’s clear lead in the direct comparison, reflects how each chip stacks against a broad field of other processors. The nearest rivals for the i5-4670S include the Intel Core i5-7440HQ at an average score of 1527 (0% delta), the Intel Pentium Gold G7400E at 1524 (0.1% delta), the Intel Xeon E5-1428L v2 at 1537 (-0.7% delta), and the Intel Core i7-8665U at 1513 (0.9% delta). The Opteron 6344’s nearest rivals are the Intel Core i5-4590S at 1493 (0% delta), the Intel Core i7-3770S at 1498 (-0.4% delta), the Intel Core i3-8100T at 1500 (-0.5% delta), and the Intel Core i5-7500T at 1483 (0.6% delta). Both chips compete in a similar performance tier when judged by average score, despite the Opteron’s decisive head-to-head advantage.

Where Each One Wins

The AMD Opteron 6344 wins in every category that the head-to-head data covers. In multi-core workloads, the Opteron’s 12 physical cores and 12 threads provide a 13.7% lead in Cinebench R15 and a 13.6% lead in R23. These are rendering workloads that scale with thread count, and the Opteron’s advantage holds even though its base clock of 2.60 GHz is lower than the i5-4670S’s 3.10 GHz base and 3.80 GHz boost. The i5-4670S’s four cores and four threads cannot overcome the Opteron’s raw core count in these tests.

Single-core performance also favors the Opteron, despite the Intel chip’s higher clock speeds. The i5-4670S boosts to 3.80 GHz, but the Opteron, running at 2.60 GHz base and 3.20 GHz boost, still manages a 13.7% higher single-core Cinebench R15 score. This indicates that the Opteron’s Piledriver architecture, while older, delivers competitive per-thread throughput in these specific workloads. The single-core margins are identical to the multi-core margins, which is unusual: most processors show different ratios between single-thread and multi-thread scaling.

The Intel Core i5-4670S has no recorded wins in the head-to-head data. Its strengths lie outside the benchmark suite: it supports PCIe Gen 3, includes integrated Intel HD 4600 graphics, and has a 65 W TDP compared to the Opteron’s 115 W. It also uses a 22 nm process versus the Opteron’s 32 nm process. But in the measured Cinebench tests, the Intel part loses every comparison. Users who need integrated graphics or lower power draw might prefer the i5-4670S, but those criteria are not reflected in the benchmark results.

The Opteron’s other advantages include ECC memory support, quad-channel DDR3 memory with 59.7 GB/s bandwidth, and a server-class feature set. The i5-4670S has dual-channel DDR3 and no ECC support. The Opteron targets the server and workstation segment, while the i5-4670S is a desktop part. That positioning explains the Opteron’s higher core count and memory bandwidth, though it also explains its higher TDP and lack of integrated graphics.

The Verdict

The data is unambiguous: the AMD Opteron 6344 outperforms the Intel Core i5-4670S in every head-to-head benchmark recorded. The Opteron leads by 13.6% to 13.8% across six Cinebench tests, covering both single-core and multi-core workloads and spanning the R15, R20, and R23 versions. The i5-4670S records zero wins. For anyone choosing between these two based purely on the benchmark results, the Opteron is the faster processor.

The i5-4670S does offer compensating features. It runs at a lower 65 W TDP, includes Intel HD 4600 integrated graphics, supports PCIe Gen 3, and uses a newer 22 nm manufacturing process with a smaller 177 mm² die. The Opteron, by contrast, has a 115 W TDP, no integrated graphics, PCIe Gen 2, and a 32 nm process with a dual-die design measuring 2x 315 mm². The Opteron also launched with an MSRP of $415, though pricing considerations are separate from the performance data.

The Opteron’s server pedigree shows in its memory subsystem: quad-channel DDR3 with 59.7 GB/s bandwidth and ECC support, versus the i5-4670S’s dual-channel DDR3 without ECC. The Opteron uses an AMD Socket G34, while the i5-4670S uses Intel Socket 1150. The Opteron is marked end-of-life in the database, while the i5-4670S has no production status listed. The Opteron’s 2,400 million transistors on a 32 nm GlobalFoundries process compare to the i5-4670S’s 1,400 million transistors on a 22 nm Intel process.

The verdict depends on the use case. For multi-threaded rendering, the Opteron wins. For single-threaded rendering, the Opteron also wins. Every measured workload favors the AMD part. The i5-4670S’s advantages are power efficiency, integrated graphics, and platform modernity, none of which appear in the benchmark scores. Based strictly on the recorded data, the Opteron 6344 is the more performant CPU.

The AMD Opteron 6344 belongs to the Opteron 6000 series and uses the Piledriver architecture under the codename Abu Dhabi. It is manufactured on a 32 nm process by GlobalFoundries. The chip has 12 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 3.20 GHz. The die is dual, measuring 2x 315 mm², and contains 2,400 million transistors. Cache is laid out as 576 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. The memory controller supports quad-channel DDR3 with ECC and reaches 59.7 GB/s of bandwidth. The platform uses AMD Socket G34 and PCIe Gen 2. The part number is OS6344WKTCGHK, and the multiplier is locked.

The TDP gap is significant: the i5-4670S consumes 65 W, while the Opteron 6344 consumes 115 W. The Intel part is a desktop segment product with integrated Intel HD 4600 graphics; the Opteron is a server or workstation part with no integrated graphics. The Opteron is marked as end-of-life in the database, while the i5-4670S has no production status listed. The i5-4670S launched in June 2013, and the Opteron launched in November 2012. The Opteron’s launch MSRP was $415.

The core count difference explains much of the multi-core behavior: 12 physical cores versus 4. The cache hierarchy also differs, with the Opteron offering per-die L3 and module-based L2, while the i5-4670S uses per-core L1 and L2 with a shared L3. The Opteron’s quad-channel memory bus provides substantially more bandwidth than the i5-4670S’s dual-channel setup. The process node difference, 22 nm versus 32 nm, gives the Intel part a density and efficiency advantage. The Opteron’s dual-die design suggests it is built as two modules on a single package, consistent with its server heritage.

Both processors have locked multipliers, so neither offers manual overclocking through the multiplier. Both support DDR3 memory, though with different channel counts and ECC capabilities. Neither processor has a listed 3D V-Cache option. The i5-4670S uses a newer generation of Intel architecture, Haswell, while the Opteron uses AMD’s Piledriver, which is a later iteration of the Bulldozer-derived design. The benchmark data shows that despite the Intel part’s architectural recency and higher clock speeds, the Opteron maintains a consistent lead across all recorded Cinebench tests.
