AMD Ryzen Embedded V1605B vs Intel Pentium Silver N6005 Comparison

Head-to-Head Benchmarks

The recorded data presents a split picture across the two Cinebench generations. In the older Cinebench R15 suite, the AMD Ryzen Embedded V1605B takes clear wins. In the multicore test, the AMD part scores 654 against 447 for the Intel Pentium Silver N6005, a delta of -31.7% from the Intel side, meaning the AMD processor leads by roughly 46%. The single-core R15 result is even more lopsided: the AMD chip posts 128 versus 63, a -50.8% delta, which translates to more than double the performance of the Intel part. These are substantial margins, indicating that in the R15 workload, the Ryzen Embedded V1605B's higher boost clock and simultaneous multithreading (SMT) deliver a decisive advantage.

However, the newer Cinebench R23 benchmark flips the multicore result entirely. Here, the Intel Pentium Silver N6005 scores 4444 versus 3160 for the AMD Ryzen Embedded V1605B, a delta of 40.6% in Intel's favor. This is a remarkable reversal. The Intel part, despite having only 4 threads versus 8, outperforms the AMD chip by a wide margin in this workload. The R23 single-core test, though, still favors AMD: 841 for the Ryzen versus 627 for the Pentium Silver, a -25.4% delta, meaning AMD leads by about 34%. So the pattern is consistent in single-core across both suites: AMD wins. In multicore, the results depend heavily on the benchmark generation, with Intel taking the modern R23 test by a large margin.

Looking at the average benchmark scores, the two processors sit at nearly identical overall levels. The Intel Pentium Silver N6005 has an average score of 1218, while the AMD Ryzen Embedded V1605B averages 1196. Both land at the 34th percentile among all CPUs in the database. The nearest rivals for the Intel part include the Intel Core i7-3632QM at 1219 (-0.1%), the Intel Core i5-2500 at 1220 (-0.2%), the Intel Xeon E5-1607 v3 at 1212 (+0.5%), and the Intel Core i3-7300T at 1211 (+0.6%). These deltas are all within 1%, placing the Pentium Silver N6005 in a tight cluster of older desktop and mobile parts. The AMD Ryzen Embedded V1605B's nearest rivals are the AMD Opteron 3365 at 1194 (+0.2%), the AMD Athlon PRO 300U at 1193 (+0.2%), the Intel Core i3-4170 at 1193 (+0.3%), and the Intel Core i7-8665UE at 1193 (+0.3%). Again, all within a fraction of a percent. The overall picture is that these two chips, despite their architectural differences, land in the same performance tier when averaged across all recorded tests.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Pentium Silver N6005 uses the Tremont architecture, part of the Jasper Lake family, built on Intel's 10 nm process with a die size of 63.8 mm². It has 4 cores and 4 threads, meaning no simultaneous multithreading. The cache layout is notable: 64 KB of L1 per core, 1.5 MB of shared L2, and 4 MB of shared L3. The base clock is 2000 MHz with a boost clock of 3.30 GHz, and the thermal design power (TDP) is 10 watts. Memory support includes DDR4 and LPDDR4 in dual-channel configuration, with a recorded memory bandwidth of 46.9 GB/s. The integrated graphics are Intel UHD Graphics with 32 execution units. The chip uses an Intel BGA 1338 socket and is categorized as a mobile segment part. It is marked as end-of-life in production status.

The AMD Ryzen Embedded V1605B, by contrast, uses the Zen architecture, codenamed Zen (Great Horned Owl), built on a 14 nm process at GlobalFoundries. The die size is substantially larger at 210 mm², and the transistor count is listed at 4,950 million. It also has 4 cores but 8 threads, enabling simultaneous multithreading. The cache structure differs: 128 KB of L1 per core, 512 KB of L2 per core, and 2 MB of shared L3. The base clock is also 2000 MHz, but the boost clock is higher at 3.60 GHz. The TDP is 15 watts, 5 watts higher than the Intel part. Memory support is DDR4 in dual-channel configuration, and the integrated graphics are Radeon Vega 8. It uses an AMD Socket FP5 and is classified as a desktop market segment part, with active production status and a release date in early 2018.

The process node difference is significant: 10 nm for Intel versus 14 nm for AMD. The Intel die is much smaller at 63.8 mm² versus 210 mm², reflecting the denser process and simpler core design. The AMD chip has nearly double the L1 cache per core and a per-core L2 design, whereas Intel uses a shared L2 pool. The L3 cache favors Intel in total capacity: 4 MB shared versus 2 MB shared for AMD. The boost clocks favor AMD by 300 MHz, and the TDP favors Intel by 5 watts. Neither chip supports ECC memory, and neither has an unlocked multiplier. The Intel part has a PCIe Gen 3 interface with 8 lanes (CPU only), while the AMD part has no PCIe information recorded.

The Verdict

The data shows two processors that average out to nearly identical overall performance, but with very different workload characteristics. The AMD Ryzen Embedded V1605B is the stronger choice for single-threaded tasks and for older Cinebench R15 workloads, where it leads by margins of 31.7% to 50.8%. It also carries 8 threads versus 4, which should benefit heavily threaded applications that scale with thread count. The higher boost clock of 3.60 GHz versus 3.30 GHz likely contributes to its single-core wins.

The Intel Pentium Silver N6005, however, wins the modern Cinebench R23 multicore test by 40.6%, a substantial margin. This suggests that in contemporary rendering workloads, the Intel architecture is more efficient despite having half the threads. The lower TDP of 10 watts versus 15 watts also makes the Intel part more attractive for thermally constrained environments. The Intel chip's average score of 1218 is marginally higher than the AMD's 1196, though both sit at the 34th percentile.

For a user prioritizing modern multicore rendering performance and lower power consumption, the Intel Pentium Silver N6005 has the edge based on the R23 result. For users with workloads that resemble the older Cinebench R15 test, or that benefit from higher single-thread scores and additional threads, the AMD Ryzen Embedded V1605B is the better fit. The overall averages are too close to declare a universal winner; the choice depends entirely on the specific workload mix.

Where Each One Wins

The Intel Pentium Silver N6005 wins in the Cinebench R23 multicore benchmark, scoring 4444 against 3160, a 40.6% advantage. This is its single recorded benchmark win, and it is a large one. The lower TDP of 10 watts also favors Intel for low-power embedded or mobile applications. The larger L3 cache of 4 MB shared could contribute to its strong showing in the modern rendering test. The Intel part also holds a slightly higher average benchmark score of 1218 versus 1196, though the difference is minimal.

The AMD Ryzen Embedded V1605B wins the other three head-to-head benchmarks. In Cinebench R15 multicore, it scores 654 versus 447, a 46% lead. In Cinebench R15 single-core, it scores 128 versus 63, more than doubling the Intel score. In Cinebench R23 single-core, it scores 841 versus 627, a 34% lead. The AMD chip also has double the thread count, which should help in multi-threaded applications that are not represented by the R23 multicore result. The higher boost clock of 3.60 GHz and the larger per-core L1 and L2 caches likely drive its single-core dominance. The AMD part is also active in production, while the Intel part is end-of-life, which matters for new designs. The Radeon Vega 8 integrated graphics may offer different capabilities than the Intel UHD Graphics 32EU, though no graphics benchmarks are recorded in the data.

In summary, the Intel Pentium Silver N6005 is the pick for modern multicore rendering and low-power scenarios, while the AMD Ryzen Embedded V1605B is the pick for single-threaded performance, older benchmark workloads, and applications that benefit from 8 threads.
