AMD Opteron 6386 SE vs AMD Ryzen Embedded V1807B Comparison

Head-to-Head Benchmarks

The head-to-head data is remarkably one-sided. The AMD Opteron 6386 SE wins all six recorded Cinebench comparisons against the AMD Ryzen Embedded V1807B, yet the margins are consistently narrow. Across the entire test suite, the Opteron's largest advantage is a 2% lead in Cinebench R15 single-core, where it scores 100 versus 98. Every other benchmark falls between 1.2% and 1.3%, which indicates that neither processor has a decisive performance edge in these workloads.

Looking at multi-core results, the Opteron 6386 SE posts 710 in Cinebench R15 multicore, just 1.3% ahead of the V1807B's 701. The pattern repeats in Cinebench R20 multicore: 2959 to 2921, again a 1.3% gap. Cinebench R23 multicore shows the same margin, with 7047 against 6957. Single-core results follow suit, with the Opteron leading 417 to 412 in R20 and 994 to 982 in R23, both 1.2% differences.

These margins are small enough to fall within typical run-to-run variance, but the database records them consistently in favor of the Opteron. The average benchmark scores tell a similar story: the Opteron averages 2038, while the V1807B averages 2012, a difference of about 1.3%. Both processors sit at the 45th percentile among all CPUs, meaning they occupy the same performance tier despite their architectural differences.

The nearest rival data reinforces this picture. The Opteron 6386 SE sits within 0.2% of the Intel Core i7-7700T (2039 average), the Intel Core i7-3960X (2037), and the AMD Ryzen 5 4500U (2035). The V1807B lands within 0.4% of the AMD Ryzen 7 1700 (2015), the Intel Core i5-8300H (2005), and the Intel Xeon D-1712TR (2004). In other words, both chips compete in the same neighborhood as mid-range desktop and mobile processors from several generations.

Architecture Differences

The two processors come from fundamentally different design eras and philosophies. The Opteron 6386 SE belongs to the Opteron 6000 series, built on the Piledriver architecture under the codename Abu Dhabi. It uses a 32 nm process from GlobalFoundries and packs 2,400 million transistors across a dual-die design totaling 2x 315 mm². The V1807B, by contrast, is part of the Ryzen Embedded 1000 series, based on the Zen architecture (codename Great Horned Owl). It uses a 14 nm process, also from GlobalFoundries, with 4,950 million transistors on a single 210 mm² die.

Core counts differ dramatically. The Opteron offers 16 cores and 16 threads, while the V1807B provides 4 cores and 8 threads. Despite having four times the cores, the Opteron only manages a 1.3% multi-core advantage, which shows how much more efficient the newer Zen cores are per thread. The Opteron's Piledriver design relies on module-based architecture, with 2 MB of L2 cache per module and 8 MB of L3 cache per die. The V1807B uses a more conventional layout: 128 KB of L1 per core, 512 KB of L2 per core, and 2 MB of shared L3.

Clock speeds favor the newer chip. The V1807B runs at 3.35 GHz base and 3.80 GHz boost, compared to the Opteron's 2.80 GHz base and 3.50 GHz boost. The V1807B also draws far less power at 45 W TDP versus 140 W for the Opteron, a significant efficiency gap that shows in the benchmark results: the Zen architecture achieves nearly identical scores with a fraction of the power envelope.

Memory support reflects their respective generations. The Opteron uses DDR3 with a quad-channel memory bus and a recorded bandwidth of 51.2 GB/s. The V1807B uses DDR4 with a dual-channel bus, though the database does not record a bandwidth figure for it. ECC memory is supported on the Opteron but not on the V1807B. The Opteron also lists PCIe Gen 2 support, while the V1807B has no recorded PCIe generation.

A notable difference: the V1807B includes integrated Radeon RX Vega 11 graphics, while the Opteron has no integrated graphics at all. The Opteron targets the server and workstation segment with an end-of-life production status, while the V1807B is an active desktop-class embedded part.

The Verdict

The benchmark data puts this matchup in an unusual position. The Opteron 6386 SE wins every recorded test, but the margins are so small that they carry little practical significance. A 1.2% to 2% lead across Cinebench workloads does not translate into a meaningful user experience difference for most applications.

The Opteron's advantage appears in raw core count and memory bandwidth. Its 16 cores and quad-channel DDR3 with 51.2 GB/s bandwidth suit workloads that scale across many threads and require high memory throughput. The V1807B counters with much lower power consumption (45 W versus 140 W), a newer memory standard (DDR4), integrated graphics, and a smaller physical footprint with a different socket (FP5 versus G34).

For anyone choosing between these two, the decision comes down to platform requirements rather than benchmark scores. The Opteron makes sense in legacy server environments that already use Socket G34 and require ECC memory support. The V1807B fits embedded or compact desktop builds where integrated graphics and lower power draw matter more than raw core counts. Since the V1807B is still in active production and the Opteron is end-of-life, long-term availability also favors the newer part.

The percentile ranking at 45 for both processors confirms they perform at the same overall level. The Opteron's six benchmark wins reflect a slight edge, but the database shows no scenario where the Opteron clearly outperforms the V1807B by a wide margin.

Where Each One Wins

The Opteron 6386 SE wins in every recorded benchmark, but its advantages are narrow: 1.3% in R15 multicore, 2% in R15 single-core, 1.3% in R20 multicore, 1.2% in R20 single-core, 1.3% in R23 multicore, and 1.2% in R23 single-core. These results favor the Opteron for workloads where every point matters in Cinebench-style rendering, though the margins are within noise levels.

The V1807B wins in efficiency and platform flexibility. Its 45 W TDP versus 140 W makes it suitable for power-constrained environments. The integrated Radeon RX Vega 11 eliminates the need for a discrete GPU in basic display tasks. DDR4 memory support provides a modern memory pathway, and the FP5 socket fits compact embedded designs. The V1807B is also still in active production, while the Opteron is end-of-life.

For multi-threaded server workloads that can leverage 16 cores and require ECC memory, the Opteron is the clear choice despite its age. For embedded systems, compact desktops, or applications needing integrated graphics and low power, the V1807B is the practical pick. The benchmark data shows the Opteron edges out the V1807B on raw compute, but the V1807B wins on operational characteristics that benchmarks do not capture.

Specification Differences

The two processors differ across nearly every recorded specification. The Opteron uses the Piledriver architecture on a 32 nm process, while the V1807B uses Zen on 14 nm. Transistor counts favor the V1807B at 4,950 million versus 2,400 million, despite the Opteron's larger dual-die footprint of 2x 315 mm² against the V1807B's single 210 mm² die.

Core and thread counts: 16 cores and 16 threads for the Opteron, 4 cores and 8 threads for the V1807B. Clock speeds favor the V1807B with a 3.35 GHz base and 3.80 GHz boost, versus 2.80 GHz base and 3.50 GHz boost for the Opteron. Power draws differ substantially: 140 W for the Opteron, 45 W for the V1807B.

Memory support diverges by generation. The Opteron uses DDR3 with a quad-channel bus and 51.2 GB/s bandwidth, while the V1807B uses DDR4 with a dual-channel bus and no recorded bandwidth. ECC memory is supported only on the Opteron. The Opteron lists PCIe Gen 2, while the V1807B has no recorded PCIe generation.

Cache structures differ entirely. The Opteron has 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. The V1807B has 128 KB of L1 per core, 512 KB of L2 per core, and 2 MB of shared L3. Integrated graphics appear only on the V1807B as Radeon RX Vega 11.

Sockets and market positioning differ: the Opteron uses AMD Socket G34 for server and workstation use, while the V1807B uses AMD Socket FP5 for desktop-class embedded applications. The Opteron launched in 2012 with a $1392 launch MSRP and is end-of-life, while the V1807B launched in 2018 with no recorded launch MSRP and remains active. The Opteron has a recorded part number (OS6386YETGGHK), while the V1807B does not list one in the database.
