AMD Opteron 6282 SE vs Intel Core i7-970 Comparison

Head-to-Head Benchmarks

The recorded data presents a clean sweep for the Intel Core i7-970 across every Cinebench workload in the comparison. The margin of victory is remarkably consistent, hovering in the narrow band between 2.6% and 2.9%. This uniformity suggests the performance gap is structural rather than workload-dependent, a pattern worth investigating given the vastly different core counts involved.

In Cinebench R15 multicore, the Intel part scores 562 against the AMD Opteron 6282 SE's 546, a 2.9% lead. The single-core result in the same test shows 79 versus 77, a 2.6% advantage for Intel. Moving to Cinebench R20, the multicore gap widens slightly in absolute terms: 2342 versus 2279, a 2.8% difference. The single-core R20 result mirrors this at 330 versus 321, again 2.8%. Finally, in Cinebench R23, the multicore scores are 5577 and 5427, a 2.8% margin, while single-core shows 787 versus 766, a 2.7% lead for Intel.

The most striking observation is that the AMD Opteron 6282 SE, despite carrying 16 physical cores to the Intel's 6 cores and 12 threads, cannot translate its raw core count into a multicore win. The data suggests that the Intel architecture's per-thread efficiency more than compensates for the AMD part's numerical core advantage. The Opteron's 16 threads are effectively slower threads, and the Cinebench workload appears sensitive to that per-thread throughput.

The win tally is unambiguous: 6 wins for the Intel Core i7-970, 0 wins for the AMD Opteron 6282 SE. The smallest margin is the R15 single-core at 2.6%, and the largest is the R15 multicore at 2.9%. Every other test lands at 2.7% or 2.8%. This consistency implies that the performance relationship between the two processors is stable across different Cinebench versions, which is notable because newer Cinebench releases often shift the balance between memory bandwidth and core scaling.

The Verdict

Based strictly on the benchmark data, the Intel Core i7-970 is the superior processor in every measured category. For users prioritizing raw Cinebench throughput, whether single-threaded or multi-threaded, the Intel part wins without exception. The average benchmark score reinforces this: the Intel processor averages 1613 across its benchmark suite, while the AMD Opteron 6282 SE averages 1569. That is a 44-point gap, roughly 2.8%, which aligns with the head-to-head deltas.

The percentile rankings place both processors at the 39th percentile among all CPUs in the database. This means that while the Intel part leads this specific comparison, neither processor is positioned particularly high in the broader performance hierarchy. They are, in effect, peers in the global distribution, with the Intel part merely occupying a slightly higher position within that shared percentile band.

The Intel Core i7-970's nearest rivals in the database include the Intel Core i7-10610U with an average score of 1611 (a 0.2% delta), the Intel Xeon E3-1240L v5 at 1609 (0.3% delta), and the Intel Core i3-9100T at 1620 (-0.5% delta). The AMD Opteron 6282 SE's nearest rivals are the Intel Core i3-8300 at 1564 (0.3% delta), the Intel Core i5-6600T at 1563 (0.4% delta), and the AMD Ryzen 3 1300X at 1562 (0.5% delta). These comparisons show that the Intel part sits closer to newer mainstream desktop chips, while the AMD part aligns with older or lower-tier options.

Who should pick which? The data supports a straightforward answer: any user whose workload resembles Cinebench rendering should choose the Intel Core i7-970. The AMD Opteron 6282 SE only becomes relevant if the priority shifts away from benchmark performance to other attributes, such as ECC memory support or a quad-channel memory bus, which are not captured in these Cinebench scores.

Where Each One Wins

The Intel Core i7-970 wins in every Cinebench test, so the use-case split must be derived from the specific margins and the architectural context. In single-core tests, the Intel part leads by 2.6% (R15) and 2.7% (R23). These wins indicate that the Intel core design, based on the Westmere architecture, delivers superior instruction throughput per clock compared to the AMD Bulldozer design. For applications that cannot utilize many threads, such as legacy software or lightly threaded workloads, the Intel processor is the clear choice.

In multicore tests, the Intel part leads by 2.8% to 2.9%. The AMD Opteron 6282 SE's 16 cores do provide more parallel hardware, but the benchmark data shows that Cinebench does not reward this extra parallelism enough to overcome the per-core deficit. The Intel processor's 12 threads, operating at a higher base clock of 3.20 GHz versus 2.60 GHz, appear to deliver more useful work per thread. The boost clocks are closer: 3.47 GHz for Intel versus 3.30 GHz for AMD, but the Intel part still maintains the edge.

For a server or workstation environment, the AMD Opteron 6282 SE offers features that the Intel desktop part lacks, such as ECC memory support and a quad-channel memory bus with a rated bandwidth of 51.2 GB/s. These attributes are not reflected in the Cinebench scores but could matter for memory-intensive or error-sensitive workloads. However, the benchmark data does not include any tests that would reveal such advantages. Within the scope of what is measured, the Intel part wins every scenario.

Architecture Differences

The two processors represent fundamentally different architectural philosophies. The Intel Core i7-970 is based on the Westmere architecture with the Gulftown codename, fabricated on a 32 nm process with 1,170 million transistors on a 239 mm² die. The AMD Opteron 6282 SE uses the Bulldozer architecture with the Interlagos codename, also on a 32 nm process, but packs 2,400 million transistors across a dual-die design of 2x 315 mm².

The cache layouts differ substantially. The Intel part provides 64 KB of L1 cache per core and 256 KB of L2 cache per core, along with a shared 12 MB L3 cache. The AMD part offers a total of 768 KB of L1 cache, 2 MB of L2 cache per module, and 8 MB of L3 cache per die. These configurations reflect the Bulldozer module design, where pairs of cores share resources, versus the Intel approach of dedicating cache per core.

The transistor count gap is stark: the AMD part contains more than double the transistors of the Intel part, yet it loses in every benchmark. This suggests that the Bulldozer architecture's complexity, including its shared floating-point units and module-level scheduling, did not translate into Cinebench performance. The Intel Westmere design, with traditional per-core resources, proved more efficient.

Both processors use DDR3 memory, but the Intel part implements a triple-channel bus while the AMD part uses quad-channel. The AMD part also supports ECC memory, a server-oriented feature the Intel part lacks. The PCIe interface is Gen 2 for both.

Specification Differences

The Intel Core i7-970 has 6 cores and 12 threads, while the AMD Opteron 6282 SE has 16 cores and 16 threads. The base clock differs: 3.20 GHz for Intel versus 2.60 GHz for AMD. The boost clock is 3.47 GHz for Intel and 3.30 GHz for AMD. The thermal design power is 130 W for Intel and 140 W for AMD.

The sockets are incompatible: Intel Socket 1366 versus AMD Socket G34. The Intel part targets the desktop market segment, while the AMD part is a server/workstation processor. The AMD Opteron 6282 SE has a launch MSRP of $1019; the Intel part has no recorded launch MSRP in the database.

The memory configuration differs in channel count: triple-channel for Intel, quad-channel for AMD. The AMD part supports ECC memory; the Intel part does not. The AMD part has a rated memory bandwidth of 51.2 GB/s, while no bandwidth figure is recorded for the Intel part. The transistor counts and die sizes differ as noted: 1,170 million transistors on 239 mm² for Intel, versus 2,400 million across 2x 315 mm² for AMD.

The cache hierarchies are distinct: Intel uses per-core L1 and L2 with a shared L3, while AMD uses a shared L1 pool, per-module L2, and per-die L3. Both processors are end-of-life in production status, with the Intel part released in July 2010 and the AMD part in November 2011. Neither has an unlocked multiplier. The Intel part number is SLBVF; the AMD part number is OS6282YETGGGU.
