AMD Opteron 6282 SE vs Intel Core i5-4670S Comparison

Head-to-Head Benchmarks

The recorded head-to-head data is remarkably one-sided. Across all six Cinebench comparisons, the AMD Opteron 6282 SE wins outright, with no victories for the Intel Core i5-4670S. The margin is consistent, hovering around 22% in every test. In Cinebench R15 multi-core, the Opteron scores 546 against 448 for the Intel part, a 21.9% advantage. The single-core R15 result shows 77 versus 63, a 22.2% lead. This pattern repeats in R20: multi-core 2279 versus 1870 (21.9% ahead), single-core 321 versus 263 (22.1% ahead). The R23 results follow the same trajectory, with the Opteron posting 5427 against 4454 in multi-core (21.8% ahead) and 766 versus 628 in single-core (22.0% ahead).

What stands out is that the Opteron’s lead is nearly identical across single-threaded and multi-threaded workloads. That is unusual. Typically, a 16-core server processor would dominate a 4-core desktop chip in multi-core but lose in single-core. The data shows otherwise. The Opteron’s single-core R23 score of 766 is 22% higher than the i5-4670S’s 628. This suggests that the older AMD architecture, despite its server focus, retains a raw clock-for-clock advantage in this benchmark generation, or that the Intel chip’s power-constrained S-series design limits its peak performance.

The average benchmark scores reinforce the gap. The Opteron’s average across all recorded tests is 1569, placing it in the 39th percentile of all CPUs. The i5-4670S averages 1526, sitting at the 38th percentile. The head-to-head deltas are larger than the average-score delta of roughly 2.8%, which indicates that the Cinebench suite specifically favors the Opteron’s architecture. The nearest rivals for each chip tell a different story: the Opteron’s competitors, such as the Intel Core i3-8300 at 1564 and the AMD Ryzen 3 1300X at 1562, are within 0.5% of its average. The i5-4670S’s nearest rival, the Intel Core i5-7440HQ at 1527, is within 0.1%, while the Intel Xeon E5-1428L v2 actually scores higher at 1537, a negative delta of -0.7%.

Architecture Differences

The Opteron 6282 SE is built on AMD’s Bulldozer architecture, codenamed Interlagos, and belongs to the Opteron 6000 series. It uses a 32 nm process with a die composed of two 315 mm² chips, totaling 2,400 million transistors. The chip has 16 cores and 16 threads, with a base clock of 2.60 GHz and a boost clock of 3.30 GHz. Its cache layout is modular: 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. Memory support is DDR3 over a quad-channel bus, yielding a theoretical bandwidth of 51.2 GB/s. ECC memory is supported, which aligns with its server/workstation market segment. The socket is AMD Socket G34, and PCIe is Gen 2. The package carries a 140 W TDP and was released in November 2011, with a launch MSRP of $1019. The part number is OS6282YETGGGU.

The Intel Core i5-4670S uses the Haswell architecture, also its codename, and is a desktop part. It is manufactured on Intel’s 22 nm process with 1,400 million transistors on a 177 mm² die. The chip has 4 cores and 4 threads, with a base clock of 3.10 GHz and a boost clock of 3.80 GHz. Cache is per-core: 64 KB of L1 and 256 KB of L2 per core, with 6 MB of shared L3. Memory support is DDR3 over a dual-channel bus, but the database does not record a bandwidth figure for this chip. ECC memory is not supported. It uses Intel Socket 1150, has PCIe Gen 3, and includes integrated graphics in the form of Intel HD 4600. The TDP is 65 W, and the release date is June 2013. The part number is SR14K.

The architectural contrast is stark. The Opteron is a dual-die server processor with a modular cache hierarchy and quad-channel memory, built for throughput in multi-socket systems. The i5-4670S is a monolithic desktop chip with a unified L3, dual-channel memory, and integrated graphics, built for power efficiency. The Opteron has four times the cores, but its per-module L2 design and dual-die L3 arrangement are optimized for server workloads, not latency-sensitive desktop tasks. The i5-4670S’s integrated GPU is a feature the Opteron entirely lacks, and its PCIe Gen 3 support is a generation ahead of the Opteron’s Gen 2.

FAQ

Q: Which processor wins more benchmarks in the head-to-head comparisons?

A: The AMD Opteron 6282 SE wins all six recorded head-to-head Cinebench tests. The Intel Core i5-4670S does not win any. The Opteron’s margin is consistent, ranging from 21.8% to 22.2% across multi-core and single-core tests.

All four rivals are within 0.6% of the Opteron’s average.

Q: Does the i5-4670S have any benchmark where it outperforms its nearest rivals?

A: The database shows the i5-4670S’s average score is 1526. Its nearest rival, the Intel Xeon E5-1428L v2, scores 1537, which is 0.7% higher, meaning the Xeon beats it. The Intel Core i5-7440HQ scores 1527 (0% delta), the Intel Pentium Gold G7400E scores 1524 (0.1% behind), and the Intel Core i7-8665U scores 1513 (0.9% behind).

A: The Opteron 6282 SE has a base clock of 2.60 GHz and a boost clock of 3.30 GHz. The Intel Core i5-4670S has a base clock of 3.10 GHz and a boost clock of 3.80 GHz. The Intel chip is higher in both base and boost frequencies, yet it still loses in all single-core Cinebench comparisons.

Q: Which chip supports ECC memory?

A: The AMD Opteron 6282 SE supports ECC memory. The Intel Core i5-4670S does not. This aligns with the Opteron’s server/workstation market segment, where error-correcting memory is a standard requirement.

A: The Opteron uses a quad-channel DDR3 bus with a recorded bandwidth of 51.2 GB/s. The i5-4670S uses a dual-channel DDR3 bus, but the database does not record a bandwidth figure for it. The Opteron’s wider memory bus is a direct consequence of its server design.

Specification Differences

The two processors differ in nearly every measurable specification. The Opteron has 16 cores and 16 threads, while the i5-4670S has 4 cores and 4 threads. Base clocks differ: 2.60 GHz for the Opteron, 3.10 GHz for the Intel chip. Boost clocks are 3.30 GHz and 3.80 GHz respectively. The TDP is more than double for the Opteron: 140 W versus 65 W. The sockets are incompatible: AMD Socket G34 versus Intel Socket 1150.

The process nodes differ by one generation: 32 nm for AMD, 22 nm for Intel. Transistor counts are 2,400 million versus 1,400 million, and die sizes are 2x 315 mm² versus 177 mm². Cache layouts are fundamentally different: the Opteron has 768 KB L1, 2 MB L2 per module, and 8 MB L3 per die; the i5-4670S has 64 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3.

Memory support is DDR3 for both, but the Opteron runs quad-channel with 51.2 GB/s bandwidth, while the i5-4670S runs dual-channel with no recorded bandwidth. ECC memory is available only on the Opteron. PCIe versions differ: Gen 2 for AMD, Gen 3 for Intel. The Opteron has no integrated graphics; the i5-4670S includes Intel HD 4600. Market segments are server/workstation versus desktop. Release dates are November 2011 versus June 2013. The Opteron has a recorded launch MSRP of $1019, while the i5-4670S has no recorded launch MSRP. Neither chip has an unlocked multiplier.

The Verdict

The data points to a clear performance winner in the recorded benchmarks: the AMD Opteron 6282 SE. It leads the Intel Core i5-4670S by roughly 22% in every Cinebench test, both single-core and multi-core. The Opteron’s average benchmark score of 1569 exceeds the i5-4670S’s 1526, and its percentile ranking (39th) is one point higher. For workloads that resemble Cinebench rendering, the Opteron is the better choice based on the recorded numbers.

However, the i5-4670S has advantages that the benchmark suite does not capture. It has a much lower TDP of 65 W versus 140 W, which implies significantly lower power consumption and heat output. It includes integrated graphics, which the Opteron lacks entirely, meaning a system with the i5-4670S does not require a discrete GPU for basic display output. It also supports PCIe Gen 3, which is a newer standard than the Opteron’s Gen 2.

The choice depends on the use case. For a server or workstation environment where multi-threaded throughput, ECC memory, and quad-channel bandwidth are priorities, the Opteron’s 16 cores and 22% benchmark lead make it the data-supported pick. For a desktop system where power efficiency, integrated graphics, and a newer PCIe standard matter more, the i5-4670S is the rational selection, despite losing every recorded benchmark. The average-score data further suggests that both chips sit near comparable rivals: the Opteron’s closest competitor, the Core i3-8300, is only 0.3% away, while the i5-4670S’s closest rival, the Core i5-7440HQ, is at a 0% delta. Neither chip is an outlier in its class; they are simply different tools for different jobs.
