AMD Opteron 3365 vs Intel Pentium Silver N6005 Comparison

FAQ

Q: Which processor has more cores and threads?

A: The AMD Opteron 3365 has 8 cores and 8 threads, while the Intel Pentium Silver N6005 has 4 cores and 4 threads. Despite having half the core count, the Intel part wins all head-to-head benchmark comparisons.

Q: What are the benchmark score differences between the two?

A: In every recorded test, the Intel Pentium Silver N6005 leads. The largest gap is in Cinebench R20 single-core, where Intel scores 263 versus AMD's 205, a 28.3% advantage. The multicore deltas are consistently 28.1% across R15, R20, and R23 tests.

Q: How do their average benchmark scores compare?

A: The Intel Pentium Silver N6005 has an average benchmark score of 1218, while the AMD Opteron 3365 averages 1194. Both sit at the 34th percentile among all CPUs in the database.

Q: Which processor supports faster memory bandwidth?

A: The Intel Pentium Silver N6005 supports DDR4 and LPDDR4 memory with a bandwidth of 46.9 GB/s. The AMD Opteron 3365 supports DDR3 only, with a bandwidth of 29.9 GB/s. That is a 57% higher memory bandwidth figure for Intel.

Q: Are there differences in the integrated graphics?

A: Yes. The Intel Pentium Silver N6005 includes UHD Graphics 32EU on-die. The AMD Opteron 3365 has no integrated graphics of its own, relying on chipset features found on certain motherboards.

Q: What is the production status of each chip?

A: Both processors are end-of-life. The Intel part is classified as a mobile segment chip, while the AMD part is positioned for the server/workstation segment.

The Verdict

The benchmark data is unambiguous: the Intel Pentium Silver N6005 is the superior performer across every recorded workload. It wins all 5 head-to-head comparisons, with deltas ranging from 28.1% to 28.3%. The AMD Opteron 3365, despite having twice the core count, never takes a single win.

For buyers choosing between these two end-of-life parts, the Intel Pentium Silver N6005 is the clear pick for any application where raw single-threaded and multi-threaded rendering performance matters. Its 28.1% lead in Cinebench R23 multicore (4444 vs 3470) and 28.2% edge in single-core (627 vs 489) make it the stronger option for content creation or general productivity.

The AMD Opteron 3365, with its 8 cores and 65W TDP, might appeal to those specifically needing a server/workstation form factor on Socket AM3+. However, the data shows its performance is consistently below the Intel part. The Opteron's only advantage is core count, which does not translate into benchmark victories.

The Intel Pentium Silver N6005 also offers superior memory bandwidth (46.9 GB/s vs 29.9 GB/s), a newer process node, and integrated graphics. Unless a platform requirement forces the AM3+ socket, the Intel chip is the better choice based on recorded measurements.

Head-to-Head Benchmarks

The Intel Pentium Silver N6005 dominates every recorded comparison. In Cinebench R15 multicore, Intel scores 447 against AMD's 349, a 28.1% advantage. The same 28.1% delta appears in Cinebench R20 multicore (1866 vs 1457) and Cinebench R23 multicore (4444 vs 3470).

Single-core results show a slightly larger gap. Cinebench R20 single-core gives Intel 263 versus AMD's 205, a 28.3% lead. Cinebench R23 single-core follows with Intel at 627 and AMD at 489, a 28.2% difference. The consistency of these deltas across both single and multi-threaded tests suggests the Intel architecture delivers a uniform performance advantage.

The only other benchmark recorded for Intel but not AMD is Geekbench, where the Pentium Silver N6005 scores 1469 multicore and 564 single-core. The Opteron 3365 has no Geekbench scores in the database, so no direct comparison is possible there.

The avgBenchmarkScore metric tells a similar story: Intel at 1218 versus AMD at 1194, a 2% overall difference. However, the head-to-head Cinebench tests reveal a much larger gap, indicating that the average score is pulled closer by other factors. The Intel part's nearest rivals include the Intel Core i7-3632QM (1219, 0.1% higher) and Intel Core i5-2500 (1220, 0.2% higher), while AMD's nearest rivals include the AMD Athlon PRO 300U and Intel Core i3-4170, both at 1193 (0.1% higher than AMD). This places both CPUs in the same performance tier overall, but the head-to-head data shows Intel's strength in rendering workloads.

Specification Differences

The two processors differ in nearly every specification category. The Intel Pentium Silver N6005 has 4 cores and 4 threads, while the AMD Opteron 3365 doubles that to 8 cores and 8 threads. Base clocks are 2000 MHz for Intel and 2300 MHz for AMD, yet both boost to 3300 MHz.

Thermal design power differs dramatically: Intel is rated at 10W, AMD at 65W. This 6.5x difference in TDP means the Intel chip is far more power-efficient per unit of performance. Socket compatibility is entirely different as well: Intel uses BGA 1338, AMD uses AM3+.

Memory support shows Intel supporting DDR4 and LPDDR4, while AMD is limited to DDR3. Memory bandwidth figures are 46.9 GB/s for Intel and 29.9 GB/s for AMD. PCIe generations differ, with Intel at Gen 3 with 8 lanes (CPU only) and AMD at Gen 2. Intel includes UHD Graphics 32EU, while AMD relies on chipset features for display output.

Process nodes are also dissimilar: Intel uses 10 nm, AMD uses 32 nm. The die sizes reflect this, with Intel at 63.8 mm² versus AMD's 315 mm². AMD lists 1,200 million transistors, while Intel does not report a transistor count in the database.

Architecture Differences

The architectural gap between these two chips is substantial. Intel's Pentium Silver N6005 uses the Tremont architecture on the Jasper Lake platform (generation: Pentium Silver, Tremont). AMD's Opteron 3365 uses the K10 architecture on the Delhi platform (generation: Opteron, Delhi). These represent different design philosophies: Tremont is a modern, efficient core design, while K10 is an older, higher-power server architecture.

Cache layouts diverge significantly. Intel provides 64 KB L1 per core, 1.5 MB shared L2, and 4 MB shared L3. AMD offers 384 KB total L1, 4 MB L2, and 8 MB shared L3. The AMD chip has more total cache, but the Intel design's smaller, faster cache hierarchy appears to deliver better performance in the recorded tests.

Manufacturing differences are stark. Intel fabricates on a 10 nm process at its own foundry. AMD uses GlobalFoundries' 32 nm process. This process advantage helps explain Intel's lower TDP (10W vs 65W) and smaller die (63.8 mm² vs 315 mm²).

The market segments differ: Intel targets mobile devices, while AMD is designed for server/workstation use. This is reflected in the Opteron's higher core count and the Pentium Silver's integrated graphics. Both processors are end-of-life, and neither has an unlocked multiplier.

The memory controllers reflect their eras: Intel supports modern DDR4/LPDDR4 with dual-channel configuration, AMD supports older DDR3 with dual-channel. Intel's PCIe Gen 3 with 8 CPU lanes offers more bandwidth than AMD's Gen 2 implementation. ECC memory is not supported by either chip, and neither has 3D V-Cache.

In the benchmark data, the Intel architecture's efficiency wins out over the AMD chip's higher core count. The 10 nm Tremont design delivers 28.1% better multicore performance while using far less power. This demonstrates that architectural efficiency can overcome a 2x core disadvantage in these specific workloads.
