AMD Ryzen Embedded V3C14 vs Intel Xeon E-2126G Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD Ryzen Embedded V3C14 across all six shared Cinebench tests, with no benchmark wins for the Intel Xeon E-2126G. The margin is remarkably consistent, hovering near 13.5% in every workload. In Cinebench R15 multicore, the AMD part scores 1017 against the Intel’s 896, a 13.5% advantage. The single-core R15 result follows the same pattern: 143 versus 126, again 13.5% ahead.

Moving to Cinebench R20, the AMD Ryzen Embedded V3C14 posts 4241 in multicore versus 3734 for the Intel Xeon E-2126G, a 13.6% lead. The single-core R20 numbers are 598 and 527, respectively, which computes to a 13.5% edge. In the more demanding Cinebench R23 suite, the AMD processor reaches 10099 in multicore while the Intel chip manages 8891, a 13.6% gap. Single-core R23 shows 1425 against 1255, a 13.5% difference.

These deltas are unusually uniform, which suggests the performance gap is driven by per-clock efficiency rather than by workload-specific scaling behavior. The AMD part wins by the same relative amount in lightly threaded and fully threaded tasks, indicating that its architectural advantages translate equally across both domains. The Intel Xeon E-2126G does have a higher boost clock (4.50 GHz versus 3.80 GHz for the AMD), yet it still trails in every single-core test, which points to a substantial instructions-per-clock deficit for the Intel Coffee Lake design.

One notable observation is that the Intel Xeon E-2126G has two additional physical cores (6 versus 4), but the AMD part’s simultaneous multithreading (8 threads versus 6) plus its newer core architecture more than compensates. The multicore deficits for Intel range from 13.5% to 13.6%, which is a sizable margin given the core count disadvantage for AMD. The database’s average benchmark scores reflect a similar ordering: the AMD Ryzen Embedded V3C14 averages 2921, while the Intel Xeon E-2126G averages 2842, a difference of roughly 2.8% in the aggregate. Both parts sit at the 51st percentile among all CPUs, placing them squarely in the mid-range of the database’s distribution.

Architecture Differences

The two processors represent fundamentally different design philosophies and manufacturing eras. The AMD Ryzen Embedded V3C14 uses the Zen 3+ architecture on TSMC’s 6 nm process, with the Rembrandt codename. The Intel Xeon E-2126G relies on the older Coffee Lake architecture, fabricated on Intel’s 14 nm process with the Coffee Lake-S WS codename. This process gap is substantial: 6 nm versus 14 nm, which partially explains the AMD part’s dramatically lower power envelope.

Core counts differ as noted: the AMD chip has 4 cores and 8 threads, while the Intel chip has 6 cores and 6 threads. The Intel part lacks hyper-threading, so its thread count equals its core count. Cache hierarchies also diverge. Both share a 64 KB L1 per core, but the AMD part has 512 KB L2 per core, double the Intel’s 256 KB per core. For L3, the AMD Ryzen Embedded V3C14 has 8 MB shared, whereas the Intel Xeon E-2126G has 12 MB shared. The larger L3 on the Intel side does not translate into benchmark wins, likely because the AMD’s higher-bandwidth memory subsystem compensates.

Memory support marks a clear generational split. The AMD processor supports DDR5 with a dual-channel bus and a recorded memory bandwidth of 76.8 GB/s. The Intel processor supports DDR4, also dual-channel, but its memory bandwidth is listed at 42.7 GB/s. That is a 79.9% bandwidth advantage for the AMD part, which helps explain the consistent single-core and multicore leads in memory-sensitive Cinebench workloads. Both CPUs support ECC memory, which is expected for embedded and workstation-class parts.

PCIe connectivity also differs. The AMD Ryzen Embedded V3C14 provides Gen 4 with 20 lanes (CPU only), while the Intel Xeon E-2126G provides Gen 3 with 16 lanes (CPU only). The newer PCIe generation and additional lanes give the AMD part an interface advantage for expansion and storage. The Intel chip includes integrated graphics, specifically HD Graphics P630, while the AMD part lists no integrated graphics in the database.

The AMD processor is built on a newer socket (AMD Socket FP7) compared to the Intel Socket 1151. The Intel part has a measured die size of 154 mm², while no die size is recorded for the AMD chip. Production status also differs: the AMD Ryzen Embedded V3C14 is listed as Active, whereas the Intel Xeon E-2126G is End-of-life. Release dates are far apart, with the AMD part launching on 2022-09-26 and the Intel part on 2018-07-11, a gap of over four years that explains the architectural and process disparities.

FAQ

The TDP difference is stark: 15 W for the AMD part versus 80 W for the Intel part. That is a 5.3x lower power envelope for the AMD processor, which is remarkable given that it outperforms the Intel chip in every benchmark. The base and boost clocks are higher on the Intel side (3.30/4.50 GHz versus 2.30/3.80 GHz), yet the AMD part wins all tests, confirming that clock speed alone does not determine performance.

Where Each One Wins

The AMD Ryzen Embedded V3C14 is the clear winner in every measured benchmark category, so its use cases are straightforward. It excels in power-constrained environments where its 15 W TDP provides a massive efficiency advantage over the Intel part’s 80 W TDP. The data shows that the AMD chip delivers 13.5% to 13.6% higher performance across all Cinebench versions while consuming only a fraction of the power budget. This makes it the preferred choice for compact embedded systems, fanless designs, or any deployment where thermal dissipation and energy consumption are primary constraints.

The AMD part also wins on platform modernity. Its DDR5 memory support with 76.8 GB/s bandwidth, PCIe Gen 4 connectivity with 20 lanes, and newer 6 nm process all point to a longer useful lifespan in new designs. The Active production status means it remains available for ongoing system integration, whereas the Intel part is End-of-life. For new designs that require ECC memory, the AMD Ryzen Embedded V3C14 offers that capability alongside superior performance.

The Intel Xeon E-2126G retains some niche advantages. It has integrated graphics (HD Graphics P630), which the AMD part lacks entirely. Systems that require a display output without a discrete GPU would need to consider this, though the absence of integrated graphics on the AMD side may not be a limitation in headless embedded applications. The Intel part also has a larger L3 cache (12 MB versus 8 MB), though this does not translate into benchmark wins. Its higher boost clock (4.50 GHz) might appeal to workloads that are extremely latency-sensitive and do not rely on memory bandwidth, but the recorded Cinebench data does not show any such benefit.

The Intel part’s market segment is listed as Server/Workstation, while the AMD part is listed as Desktop, which may influence platform selection in enterprise environments with standardized Intel-only validation. However, from a pure performance standpoint, the database shows no scenario where the Intel Xeon E-2126G beats the AMD Ryzen Embedded V3C14. The Intel chip’s only clear advantages are its integrated GPU, its larger L3 cache, and its higher clock speeds, none of which produce a win in the six head-to-head benchmarks. For workloads that follow the Cinebench pattern, which is typical of rendering and multi-threaded productivity, the AMD Ryzen Embedded V3C14 is the faster and more efficient processor.
