AMD Opteron 6376

The AMD Opteron 6376 is a 16-core, 16-thread server/workstation processor built on AMD’s Piledriver architecture and codenamed Abu Dhabi. It is manufactured on a 32 nm process at GlobalFoundries, with 2,400 million transistors and a die configuration of 2x 315 mm². The chip runs at a 2.30 GHz base clock and a 3.20 GHz boost clock on AMD Socket G34, with a 115 W TDP. Its average benchmark score is 1370, which places it at the 37th percentile among all CPUs in the database. The production status is end-of-life, and the market segment is server/workstation.

How It Compares

Against the Intel Core i5-4690, the Opteron 6376 has an average score of 1370 versus the rival’s 1371. The delta is -0.1%, meaning the Opteron trails by a negligible 0.1% in aggregate performance. The two chips are effectively tied on the overall benchmark metric.

Against the Intel Core i7-3740QM, the Opteron trails by 0.4%. The rival posts an average score of 1375, while the Opteron posts 1370. This is a slightly larger gap than the i5-4690 comparison, but the delta remains small in absolute terms.

Against the Intel Core i5-1030NG7, the Opteron is 0.5% behind. The i5-1030NG7 averages 1377, making it the highest-scoring chip in the nearest rivals list. Among all four listed rivals, this is the largest negative delta for the Opteron.

Against the Intel Core i7-3820QM, the Opteron holds a 0.5% lead. The Opteron’s 1370 average score tops the i7-3820QM’s 1363, and the positive delta of 0.5% is the only positive comparison in the nearest rivals group. Overall, all four nearest rival deltas are within 0.5% of zero, so the Opteron 6376 sits in a tight aggregate performance cluster.

Power and Thermals

The Opteron 6376 is rated at a 115 W TDP. This TDP defines the thermal envelope that any cooling solution must handle, and it places the chip in a power class that requires a cooler built for that level of dissipation rather than an ultra-low-power solution.

The silicon behind that TDP is substantial. The processor is built on a 32 nm process and contains 2,400 million transistors across two 315 mm² dies. The architecture is Piledriver, and the die configuration is listed as 2x 315 mm². These silicon-level facts are the background for the 115 W rating.

Because the market segment is server/workstation and the socket is AMD Socket G34, the platform context points to socket-specific server cooling rather than a consumer desktop cooler platform. The absence of integrated graphics means the cooling solution does not need to account for an integrated GPU block. The 115 W figure is the only thermal specification, and it is the figure that any heatsink or thermal solution must satisfy.

Benchmark Performance

The Cinebench results show a clear pattern. In Cinebench R15, the Opteron 6376 scores 477 in the multi-core test and 67 in the single-core test. In Cinebench R20, the multi-core score is 1989 and the single-core score is 280. In Cinebench R23, the multi-core score is 4736 and the single-core score is 668.

Across each Cinebench version, the multi-core result is much larger than the single-core result. That split is consistent with a 16-core, 16-thread processor rather than a high-clock, low-core-count design. The aggregate average benchmark score is 1370, and the percentile rank is 37.

When compared with the nearest rivals, the aggregate margins are very narrow. The Opteron is 0.1% behind the Intel Core i5-4690, 0.4% behind the Intel Core i7-3740QM, 0.5% behind the Intel Core i5-1030NG7, and 0.5% ahead of the Intel Core i7-3820QM. These deltas are all within the 0.5% range, indicating that the Opteron’s average benchmark position is not far from any of these chips. However, the aggregate score hides the workload-specific behavior visible in the Cinebench multi-core and single-core numbers.

Who Should Consider It

Workloads that can use all 16 cores and 16 threads will benefit most from the Opteron 6376. The Cinebench R23 multi-core score of 4736, the R20 multi-core score of 1989, and the R15 multi-core score of 477 all point to substantial parallel throughput for heavily threaded tasks. Creation workloads such as rendering or video encoding that scale across many threads are the natural match for this core count.

The processor supports DDR3 memory over a quad-channel bus, with ECC memory and a memory bandwidth of 59.7 GB/s. That memory profile makes it relevant for reliability-sensitive server workloads where ECC is expected. The server/workstation market segment reinforces this orientation.

For office productivity, the picture is less favorable. The single-core scores are 668 in Cinebench R23, 280 in Cinebench R20, and 67 in Cinebench R15. Applications that depend on one or two threads will see much less benefit from the 16-core design. The 37th percentile overall ranking also indicates that the chip is not a top-tier performer against the full CPU field.

For gaming, the lack of integrated graphics and the low single-core Cinebench scores suggest this is not a gaming-oriented processor. The chip’s strengths are in multi-threaded server and workstation scenarios rather than lightly threaded interactive workloads.

Single-Thread vs Multi-Thread Behavior

The Cinebench results show a pronounced split between single-thread and multi-thread performance. In Cinebench R15, the multi-core score is 477 and the single-core score is 67. In Cinebench R20, the multi-core score is 1989 and the single-core score is 280. In Cinebench R23, the multi-core score is 4736 and the single-core score is 668.

The multi-core scores are far larger, which indicates that software able to spread work across the 16 cores and 16 threads can extract meaningful parallel throughput. The single-core scores are small by comparison, meaning the processor’s per-thread performance is limited. The 2.30 GHz base clock and 3.20 GHz boost clock are the clock speeds available for that single-threaded work.

For real workloads, this split matters. A heavily threaded render or batch job can approach the level suggested by the multi-core Cinebench results. A serial task that relies on one core will operate in the 67, 280, and 668 single-core performance range, depending on the Cinebench version. The aggregate average score of 1370 and the 37th percentile rank summarize the chip’s overall position, but they do not show this internal balance.

The nearest rivals have average scores from 1363 to 1377, and the Opteron is within 0.5% of all of them. Yet those rivals likely reach similar average scores through a different performance balance. The Opteron 6376 reaches its aggregate position with a 16-core Piledriver design on a 32 nm process, a 115 W TDP, and a clear multi-core emphasis in the benchmark data.
