AMD Ryzen Embedded V3C14 vs Intel Core i5-8600K Comparison

The AMD Ryzen Embedded V3C14 and Intel Core i5-8600K represent two very different design philosophies, and the benchmark data shows a clear, consistent winner. The AMD part, despite having fewer physical cores and a dramatically lower power envelope, outperforms the Intel chip in every single recorded multi-threaded and single-threaded workload. The data indicates a total sweep for AMD, with the V3C14 winning all six head-to-head Cinebench tests, while the i5-8600K records zero wins.

Head-to-Head Benchmarks

The most striking result is the uniformity of the performance gap. In Cinebench R15, R20, and R23, the AMD Ryzen Embedded V3C14 wins both single-core and multi-core tests by a nearly identical margin each time. The multi-core scores show a consistent 17.3% advantage for the AMD chip across all three Cinebench versions. Specifically, in Cinebench R15 multi-core, the V3C14 scores 1017 against the i5-8600K's 867, a 17.3% lead. This pattern repeats in Cinebench R20, where the AMD chip scores 4241 versus 3616, and in Cinebench R23, where it scores 10099 versus 8611. This consistency suggests the advantage is architectural rather than workload-specific.

Single-thread performance tells the same story, but with slightly more variance. In Cinebench R15 single-core, the V3C14 scores 143 against 122, a 17.2% lead. In Cinebench R20 single-core, the scores are 598 versus 510, again a 17.3% advantage. The Cinebench R23 single-core test shows the AMD part scoring 1425 versus 1215, also a 17.3% lead. The fact that the AMD chip wins single-threaded tests by a wide margin is particularly notable because the Intel chip has a higher boost clock, and the benchmark results indicate that the newer Zen 3+ architecture provides superior instructions per clock.

The average benchmark score in the database places the AMD Ryzen Embedded V3C14 at 2921, while the Intel Core i5-8600K sits at 2807. This difference of roughly 4% in the aggregate score is smaller than the individual Cinebench deltas, but it still places the AMD part ahead. The percentile ranking for both CPUs is identical at the 51st percentile of all CPUs, meaning they are statistically in the same performance tier overall, yet the head-to-head data shows a decisive victory for the AMD chip in every test where they are directly compared. The Intel i5-8600K does have additional Geekbench scores in the database (5997 multi-core and 1514 single-core), but these have no direct comparison from the AMD part, so they do not factor into the head-to-head result.

Architecture Differences

The performance disparity is rooted in fundamental architectural contrasts. The AMD Ryzen Embedded V3C14 is built on the Zen 3+ architecture, codenamed Rembrandt, and manufactured on a 6 nm process at TSMC. The Intel Core i5-8600K uses the older Coffee Lake architecture on Intel's 14 nm process. This process node difference is a major factor; the smaller 6 nm node allows for higher efficiency and density.

Core configuration also differs significantly. The AMD chip has 4 cores and 8 threads, utilizing simultaneous multithreading, while the Intel chip has 6 physical cores and 6 threads with no hyper-threading. Despite having two fewer physical cores, the AMD part wins all multi-threaded tests, demonstrating that its SMT implementation and higher per-core efficiency more than compensate for the core deficit. The cache hierarchies are also different: the AMD chip has 512 KB of L2 cache per core and 8 MB of shared L3 cache, while the Intel chip has 256 KB of L2 per core and 9 MB of shared L3. The larger per-core L2 on the AMD chip likely contributes to its single-threaded advantage.

Memory support is another clear divergence. The AMD V3C14 supports DDR5 memory with a dual-channel bus and a theoretical bandwidth of 76.8 GB/s. The Intel i5-8600K uses DDR4 with a dual-channel bus and a bandwidth of 42.7 GB/s. The AMD part also supports ECC memory, a feature absent on the Intel chip. PCIe connectivity differs as well: the AMD chip provides Gen 4 with 20 lanes, while the Intel chip provides Gen 3 with 16 lanes. The Intel part includes integrated UHD Graphics 630, while the AMD chip's integrated graphics are not specified in the database. The TDP figures are starkly different, with the AMD chip rated at 15 W and the Intel chip at 95 W, indicating a massive efficiency gap.

The Verdict

The data is unambiguous. The AMD Ryzen Embedded V3C14 is the superior processor in this comparison, winning every single benchmark in the head-to-head analysis. The 17.3% lead in multi-threaded performance is a substantial margin, especially considering the AMD chip does it with fewer physical cores and a TDP that is over six times lower. The Intel Core i5-8600K offers no performance advantage in any of the tested workloads. The AMD chip also brings modern features like DDR5, ECC support, and PCIe Gen 4, all of which are absent on the Intel part. The only area where the Intel chip can claim a specification advantage is in raw core count (6 versus 4) and a higher boost clock (4.30 GHz versus 3.80 GHz), but these do not translate into any benchmark wins. The verdict is clear: the AMD Ryzen Embedded V3C14 is the better choice based on performance, efficiency, and platform features.

Specification Differences

The two processors differ on every major specification line. The AMD Ryzen Embedded V3C14 has 4 cores and 8 threads, while the Intel Core i5-8600K has 6 cores and 6 threads. Base clocks differ, with the AMD chip at 2.30 GHz and the Intel chip at 3.60 GHz. Boost clocks also differ, with the AMD at 3.80 GHz and the Intel at 4.30 GHz. The TDP is a major differentiator: 15 W for the AMD versus 95 W for the Intel. The AMD chip uses the AMD Socket FP7, while the Intel chip uses Intel Socket 1151.

The architecture and process are entirely different: Zen 3+ on 6 nm for AMD versus Coffee Lake on 14 nm for Intel. Cache configurations differ, with the AMD chip having 512 KB of L2 per core and 8 MB of shared L3, while the Intel chip has 256 KB of L2 per core and 9 MB of shared L3. Memory support is split between DDR5 and DDR4, with bandwidth figures of 76.8 GB/s for AMD and 42.7 GB/s for Intel. ECC memory is supported only on the AMD part. PCIe connectivity is Gen 4 with 20 lanes for AMD versus Gen 3 with 16 lanes for Intel. The Intel chip includes UHD Graphics 630, while the AMD chip's integrated graphics are not listed. The Intel chip has an unlocked multiplier and a launch MSRP of $257, while the AMD chip does not have a recorded launch MSRP and is not multiplier unlocked. The Intel part is end-of-life, while the AMD part is active.

Where Each One Wins

The AMD Ryzen Embedded V3C14 wins in all performance categories recorded. It leads in multi-threaded workloads by 17.3% in Cinebench R15, R20, and R23. It also leads in single-threaded workloads by a similar margin. The AMD chip wins on efficiency, with a 15 W TDP versus 95 W, making it suitable for power-constrained environments. It wins on platform features, offering DDR5, ECC memory support, and PCIe Gen 4 connectivity. The AMD chip is the clear winner for any workload that benefits from higher per-core performance, and its SMT implementation allows it to outperform the Intel part's extra physical cores.

The Intel Core i5-8600K has no benchmark wins in this comparison. Its strengths are limited to specifications that do not translate into measured performance advantages. It has more physical cores, a higher base clock, and a higher boost clock, but the benchmark data shows these do not help. It has integrated graphics, which could be a deciding factor for a system that requires a display output without a discrete GPU. The Intel chip also has an unlocked multiplier, which allows for overclocking, but the database does not provide any overclocked benchmark results to validate this as a performance advantage. The Intel part's only realistic use case is a system that absolutely requires integrated graphics or relies on legacy DDR4 memory and Socket 1151 motherboards. For any pure CPU performance comparison, the data shows the AMD Ryzen Embedded V3C14 is the definitive winner.
