AMD Opteron 4280 vs Intel Core i7-2670QM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual head-to-head comparison: the AMD Opteron 4280 wins every single benchmark in which both processors appear. Across five Cinebench tests, the Opteron 4280 consistently outperforms the Core i7-2670QM by a margin of roughly 20%. The smallest delta is 20.2% in Cinebench R20 single-core, where the Opteron scores 226 against Intel's 188. The largest deltas are 20.5%, appearing in Cinebench R20 multi-core, R23 multi-core, and R23 single-core.

The multi-core results show the Opteron's advantage most clearly. In Cinebench R15 multi-core, the AMD part scores 385 versus 320 for the Intel chip, a 20.3% lead. In Cinebench R20 multi-core, the gap widens slightly to 20.5% with scores of 1607 and 1334. The R23 multi-core test shows the same relative gap: 3828 for AMD, 3177 for Intel, again a 20.5% difference. These are not marginal wins; the Opteron consistently delivers roughly one-fifth more performance across rendering workloads.

Single-core results tell a similar story, which is notable given the architectural differences between the two chips. The Opteron 4280 posts 540 in Cinebench R23 single-core versus 448 for the Core i7-2670QM, a 20.5% advantage. In R20 single-core, the scores are 226 and 188 respectively, a 20.2% delta. The consistency of these margins across both single-threaded and multi-threaded tests suggests a uniform performance gap rather than a workload-specific anomaly.

The win tally is decisive: the Opteron 4280 claims 5 wins, the Core i7-2670QM claims 0. No benchmark in the shared test set favors the Intel processor. The average benchmark scores in the database reflect this overall balance: the Opteron 4280 sits at 1107, while the Core i7-2670QM sits at 1096. Both processors occupy the 31st percentile among all CPUs, meaning they are statistically near-identical in overall standing despite the Opteron's consistent head-to-head wins. The nearest rivals for each chip reinforce this: the Opteron 4280 matches the AMD PRO A12-8870 exactly at 1107, while the Core i7-2670QM matches the Intel Core i7-2710QE exactly at 1096.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Opteron 4280 uses the Bulldozer architecture on the Valencia codename, built on a 32 nm process at GlobalFoundries. The Intel Core i7-2670QM uses Sandy Bridge, also on a 32 nm node, fabricated by Intel. Both chips share the same process generation, but their internal designs diverge sharply.

The Opteron 4280 packs 8 cores and 8 threads, while the Core i7-2670QM offers 4 cores and 8 threads thanks to Hyper-Threading. The AMD part has a base clock of 2.80 GHz and a boost clock of 3.50 GHz. The Intel chip runs at a lower 2.20 GHz base and 3.10 GHz boost. Despite having twice the physical cores, the Opteron maintains higher clock speeds across the board, which helps explain its consistent lead in both single and multi-threaded workloads.

Cache configurations differ substantially. The Opteron 4280 features a 384 KB L1 cache, 8 MB L2, and 8 MB shared L3. The Core i7-2670QM has 64 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3. The Opteron's larger cache hierarchy, particularly the 8 MB L2, provides more on-die storage for server-style workloads. Transistor counts are similar: 1,200 million for the AMD chip versus 1,160 million for Intel, but the die sizes differ markedly. The Opteron measures 315 mm², while the Core i7 is much smaller at 216 mm².

Memory support also separates the two. The Opteron 4280 supports DDR3 with dual-channel memory and a peak bandwidth of 25.6 GB/s, and it includes ECC memory support. The Core i7-2670QM also uses dual-channel DDR3 but has no ECC capability and no listed memory bandwidth figure. The Opteron includes PCIe Gen 2 support; the Intel chip's PCIe information is not recorded. Integrated graphics appear only on the Intel part: the Core i7-2670QM includes Intel HD 3000, while the Opteron has no integrated graphics, a typical difference between server and mobile processors.

The market segments reflect their intended roles. AMD positioned the Opteron 4280 for server and workstation use on the AMD Socket C32 platform. Intel designed the Core i7-2670QM for mobile systems on Intel Socket G2 (988B). Both parts are end-of-life and were released within a month of each other in late 2011. The Opteron carries a launch MSRP of $255; no launch MSRP is recorded for the Intel chip. Neither processor has an unlocked multiplier.

The Verdict

The benchmark data points to a clear performance hierarchy: the AMD Opteron 4280 is faster than the Intel Core i7-2670QM in every shared test. The consistency of the 20% margins across both single-core and multi-core workloads suggests the Opteron's advantage is architectural and clock-driven, not workload-specific. The Opteron's higher base and boost clocks, combined with double the physical cores, deliver a uniform lead.

However, the overall percentile rankings temper this conclusion. Both chips land at the 31st percentile, and their average scores differ by only 11 points (1107 versus 1096). The head-to-head deltas are large in relative terms, but in absolute performance terms these are both modest processors by modern standards. The Opteron's wins are real and repeatable across the test suite, but they do not boost it to a different performance class.

For server and workstation buyers in the database era, the Opteron 4280 offers demonstrably higher throughput in Cinebench workloads. Its ECC memory support and larger cache hierarchy reinforce its server positioning. The Core i7-2670QM, while slower in these tests, brings integrated graphics and a much lower 45 W TDP compared to the Opteron's 95 W. The Intel chip's mobile design targets power efficiency and system integration, not peak rendering performance.

The choice depends on the use case. If the priority is raw compute in multi-threaded rendering tasks, the Opteron 4280 wins outright. If the priority is a mobile platform with integrated graphics and lower power draw, the Core i7-2670QM remains the only option of the two, since it is the sole mobile part.

Specification Differences

The two processors differ across nearly every major specification category. The AMD Opteron 4280 uses 8 cores and 8 threads, while the Intel Core i7-2670QM uses 4 cores and 8 threads. Base clocks are 2.80 GHz for AMD and 2.20 GHz for Intel. Boost clocks are 3.50 GHz and 3.10 GHz respectively. TDP differs substantially: 95 W for the Opteron, 45 W for the Core i7.

Sockets are incompatible: AMD Socket C32 versus Intel Socket G2 (988B). The architectures are Bulldozer (Valencia) versus Sandy Bridge. Both use 32 nm processes, but from different foundries: GlobalFoundries for AMD, Intel for Intel. Transistor counts are close (1,200 million versus 1,160 million), but die sizes differ (315 mm² versus 216 mm²).

Cache layouts are entirely different. The Opteron has 384 KB L1, 8 MB L2, and 8 MB shared L3. The Core i7 has 64 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3. Memory support shows the Opteron with DDR3, dual-channel, 25.6 GB/s bandwidth, and ECC. The Core i7 also uses dual-channel DDR3 but has no recorded memory type, no bandwidth figure, and no ECC. The Opteron lists PCIe Gen 2; the Core i7 has no PCIe data. Integrated graphics exist only on the Intel part (Intel HD 3000). The Opteron's market segment is server and workstation; the Core i7's is mobile. The Opteron has a recorded launch MSRP of $255; the Core i7 has none. Both are end-of-life, neither has an unlocked multiplier, and their part numbers are OS4280WLU8KGU for AMD and SR02N for Intel.

Where Each One Wins

The AMD Opteron 4280 wins in every benchmark category where both processors have recorded scores. This includes Cinebench R15 multi-core, R20 multi-core, R20 single-core, R23 multi-core, and R23 single-core. The Opteron's strengths lie in multi-threaded rendering, where its 8 physical cores and higher clocks produce a 20.5% advantage in R23 multi-core. It also wins single-core tests by the same margin, indicating that its clock speed advantage (2.80 GHz base, 3.50 GHz boost) overcomes any architectural efficiency gains from Intel's Sandy Bridge design. For server and workstation workloads that rely on ECC memory and large caches, the Opteron 4280 is the clear choice.

The Intel Core i7-2670QM has no benchmark wins in the shared test set. Its advantages are structural rather than performance-based. It is the only one of the two with integrated graphics (Intel HD 3000), making it suitable for compact mobile systems that do not require a discrete GPU. Its 45 W TDP is less than half the Opteron's 95 W, which matters in thermal-constrained environments. The Intel chip also uses a smaller die (216 mm² versus 315 mm²), which is a consideration for manufacturing efficiency. The Core i7's mobile socket and lower power draw position it for laptops and portable workstations, whereas the Opteron targets rack-mounted servers and workstations where power is less constrained and raw throughput is prioritized.

The data shows no scenario where the Core i7-2670QM outperforms the Opteron 4280 in the recorded benchmarks. Buyers seeking maximum Cinebench performance should choose the AMD part. Buyers seeking a mobile processor with integrated graphics and lower power consumption should choose the Intel part, accepting the 20% performance deficit in rendering workloads.
