AMD Ryzen 9 4900H vs AMD Ryzen Embedded V2718 Comparison

# Head-to-Head Benchmarks

The benchmark data presents a divided picture between the AMD Ryzen Embedded V2718 and the AMD Ryzen 9 4900H, with each processor claiming two wins across the four shared tests. The most striking divergence appears in multi-core performance, where the two chips trade blows in opposite directions depending on the benchmark generation.

In Cinebench R15 multi-core, the Ryzen 9 4900H delivers a score of 1926.5 against the Embedded V2718's 1350, a 29.9% advantage. This is the single largest margin in either direction across the head-to-head results. The gap narrows dramatically in Cinebench R15 single-core, where the Ryzen 9 4900H edges ahead by just 1.6%, scoring 193 versus 190. That near-parity in single-threaded R15 performance is remarkable given the substantial differences in power envelope and clock strategy between the two parts.

The tables turn decisively in the Cinebench R23 tests. The Embedded V2718 scores 13396 in multi-core, which is 15.4% higher than the Ryzen 9 4900H's 11604. The single-core R23 result is even more lopsided: the Embedded V2718 reaches 1891, a 46.1% advantage over the Ryzen 9 4900H's 1294. This pattern — the Embedded part winning handily in R23 while losing in R15 — suggests that benchmark-specific optimizations and sustained boost behavior play a significant role in how these processors perform under load.

Looking at the broader benchmark picture, the Embedded V2718 posts an average benchmark score of 3875 across all recorded tests, while the Ryzen 9 4900H averages 3820. That difference is modest, roughly 1.4%, and both processors land at the 56th percentile among all CPUs tracked. The Embedded part sits between the Intel Core i7-11700T (3864, 0.3% behind) and the AMD Ryzen 5 4600GE (3906, 0.8% ahead). The Ryzen 9 4900H, meanwhile, ranks just below the Intel Xeon E-2286M (3822, -0.1%) and above the Intel Core i7-8086K (3800, 0.5%).

The R23 results are particularly noteworthy because they invert the expectation set by R15. A 46.1% single-core advantage in R23 is not a minor tuning difference; it indicates a fundamental divergence in how the two processors respond to that workload's instruction mix and caching patterns. The Embedded V2718's R23 multi-core score of 13396 also exceeds its R15 multi-core score of 1350 by a factor of roughly 9.9, while the Ryzen 9 4900H's R23-to-R15 ratio is only about 6.0. This suggests the Embedded part scales more efficiently with the longer-duration R23 workload, possibly due to more favorable boost behavior under sustained load.

# Architecture Differences

Both processors share the same fundamental architecture: Zen 2 on TSMC's 7 nm process, with the Renoir codename and a die size of 156 mm² containing 9,800 million transistors. They each pack 8 cores and 16 threads, with an identical cache hierarchy: 64 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. Both use the AMD Socket FP6 and support dual-channel memory with 51.2 GB/s of bandwidth.

The architectural divergence begins with clock speeds. The Ryzen 9 4900H has a 3.30 GHz base clock and 4.40 GHz boost clock, while the Embedded V2718 runs at 1.70 GHz base and 4.15 GHz boost. That is a 1.60 GHz difference in base clock — the Ryzen 9 4900H starts at nearly double the frequency of the Embedded part. Yet the boost clocks are much closer, with only a 0.25 GHz gap. This explains why single-threaded R15 scores are nearly identical (190 versus 193) while multi-threaded performance diverges so sharply in R15: the Ryzen 9 4900H can sustain its higher base clock across all cores, whereas the Embedded V2718 must rely on boost headroom.

Power delivery marks the other major divide. The Embedded V2718 carries a TDP of 10 watts, while the Ryzen 9 4900H is rated at 54 watts — a 44-watt gap. This is the largest single specification difference between the two parts and likely drives much of the observed performance variance. The 10-watt Embedded part cannot sustain all-core boost clocks as aggressively as the 54-watt mobile chip, which explains the R15 multi-core deficit. Yet the R23 results suggest that the Embedded part's boost behavior under certain conditions can actually exceed the Ryzen 9 4900H's output, possibly due to workload-specific power management.

Memory support differs as well. The Ryzen 9 4900H supports both DDR4 and LPDDR4, while the Embedded V2718 supports only DDR4. The Embedded part also includes ECC memory support, which the Ryzen 9 4900H lacks. This positions the Embedded V2718 for reliability-focused applications where memory integrity is critical.

Integrated graphics differentiate the two further. The Ryzen 9 4900H carries Radeon Graphics with 512 shader processors, while the Embedded V2718 has Radeon Graphics with 448 SP — a 64-SP difference. PCIe connectivity also diverges: the Embedded V2718 specifies Gen 3 with 20 lanes (CPU only), while the Ryzen 9 4900H lists simply Gen 3 without a lane count.

The production status for both is Active, and neither has an unlocked multiplier. The Embedded V2718 belongs to the 2000 series and was released on 2020-11-09, while the Ryzen 9 4900H is part of the 4000 series with a release date of 2020-03-15. Both use the same socket, meaning they are physically interchangeable in FP6 motherboards, though their power and thermal requirements differ substantially.

# Where Each One Wins

The AMD Ryzen 9 4900H wins in scenarios that favor raw sustained multi-core throughput at higher power draw. Its 29.9% advantage in Cinebench R15 multi-core demonstrates this clearly. The 3.30 GHz base clock — nearly double the Embedded part's 1.70 GHz — allows it to maintain high frequencies across all 8 cores without relying on boost headroom. This makes it the stronger choice for short, bursty multi-threaded workloads where power delivery is not a constraint. Its 54-watt TDP and additional 64 shader processors in the integrated GPU also position it well for mobile computing tasks that require both CPU and graphics throughput. The Ryzen 9 4900H's support for LPDDR4 memory broadens its compatibility with low-power memory configurations in thin-and-light laptops.

The AMD Ryzen Embedded V2718 wins in efficiency-oriented and long-duration workloads. Its 10-watt TDP is a fraction of the Ryzen 9 4900H's 54-watt rating, making it suitable for thermally constrained embedded systems. The R23 results are its strongest showing: a 15.4% multi-core advantage and a 46.1% single-core advantage over the Ryzen 9 4900H. The R23 single-core margin is particularly significant — it indicates that under that specific workload, the Embedded part's boost algorithm delivers far superior per-thread performance despite the lower base clock. ECC memory support gives it an edge in reliability-critical applications such as industrial controllers, network appliances, or edge servers where memory corruption is unacceptable. Its 20 PCIe Gen 3 lanes (CPU only) provide dedicated I/O bandwidth for embedded peripherals.

The average benchmark scores place the Embedded V2718 slightly ahead overall (3875 versus 3820), and both processors sit at the 56th percentile among all CPUs. The Embedded part's nearest rivals — the Intel Core i7-11700T (0.3% behind), AMD Ryzen 5 4600GE (0.8% ahead), and AMD Ryzen 9 5900HS (1.3% ahead) — cluster tightly around its score. The Ryzen 9 4900H's rivals — the Intel Xeon E-2286M (0.1% ahead), Intel Core i7-8086K (0.5% behind), and Intel Core i7-9700KF (0.9% behind) — are similarly close. This indicates both processors perform at nearly identical overall levels, with workload-specific factors determining the winner rather than any broad performance gap.

For embedded deployments where power efficiency and memory reliability take priority, the Embedded V2718 is the clear choice. For mobile computing where burst performance and graphics capability matter more, the Ryzen 9 4900H holds the advantage. The R23 results, however, suggest that the Embedded V2718 may surprise in scenarios involving sustained single-threaded processing, where its 46.1% lead indicates a fundamentally different boost behavior that can outperform the higher-clocked mobile chip.
