AMD Ryzen 7 2800H vs AMD Ryzen Embedded V1807B Comparison

The AMD Ryzen Embedded V1807B and AMD Ryzen 7 2800H are remarkably close siblings, sharing the same Zen architecture, 14nm process, and integrated Radeon RX Vega 11 graphics. The benchmark data shows the V1807B winning all six head-to-head Cinebench tests, but every margin is tiny, ranging from 0.5% to 0.6%. The average benchmark scores confirm this: the V1807B scores 2012 versus 2002 for the 2800H, placing both at the 45th percentile among all CPUs. The real differentiator is not raw performance but the TDP envelope—45W for the embedded part versus 15W for the mobile part—which dictates where each chip belongs.

The Verdict

Choose the AMD Ryzen Embedded V1807B if your priority is squeezing out every last point of multi-threaded performance and you have the thermal headroom to manage a 45W TDP. It wins every single benchmark in the comparison, including a 6957 vs 6922 advantage in Cinebench R23 multi-core and a 2921 vs 2907 edge in R20 multi-core. Its nearest rival, the AMD Ryzen 7 1700, scores 2015, just 0.1% higher, meaning the V1807B trades blows with a desktop octa-core from the same era.

Pick the AMD Ryzen 7 2800H when power efficiency matters more than a marginal performance lead. Its 15W TDP is one-third of the V1807B's 45W, yet it loses by only 0.5% in most tests. The 2800H's nearest rival, the Intel Core i5-8400T, scores 2001, a 0% delta, showing it sits in the same performance class. If you are building a fanless or battery-powered system where every watt counts, the 2800H delivers nearly identical results with far less heat to dissipate.

For desktop-replacement or always-plugged-in embedded systems, the V1807B's extra 0.6% in Cinebench R15 multi-core—701 vs 697—is a free win. For mobile or passively cooled designs, the 2800H is the only rational choice, as the data shows no meaningful compute penalty for its drastically lower power draw.

Architecture Differences

Both processors are built on the same Zen architecture and 14nm GlobalFoundries process, but they come from different codenames and generations. The V1807B is part of the 1000 series under the "Great Horned Owl" codename, while the 2800H belongs to the 2000 series under "Raven Ridge." Despite this generation gap, both use the same core count of 4 cores and 8 threads, and both are fabricated on identical 14nm nodes.

The cache hierarchy differs slightly. The V1807B has 2 MB of shared L3 cache, while the 2800H doubles that to 4 MB. Both have 128 KB of L1 per core and 512 KB of L2 per core. The die size also diverges: the V1807B measures 210 mm² and contains 4,950 million transistors, while the 2800H has a larger 246 mm² die with no transistor count listed in the data. This larger die with more cache suggests the 2800H dedicates more silicon to memory buffering, even though it runs at a lower TDP.

Both chips share the same AMD Socket FP5, dual-channel DDR4 memory support, and integrated Radeon RX Vega 11 graphics. Neither supports ECC memory, and neither has an unlocked multiplier. The V1807B targets the Desktop market segment, while the 2800H is classified as Mobile. The V1807B launched on 2018-02-20, roughly three months before the 2800H's 2018-05-29 release date.

Q: Is there a difference in their integrated graphics?

A: No, both chips feature the identical Radeon RX Vega 11 integrated graphics solution.

Q: How do their TDP ratings compare?

A: The V1807B is rated at 45W, while the 2800H is rated at just 15W. This is the largest specification gap between the two.

Q: Which one wins in single-core performance?

A: The V1807B wins narrowly in all single-core tests, including a 982 vs 977 result in Cinebench R23 single-core, a 0.5% difference. In R15 single-core, they tie at 98 points.

Specification Differences

The two processors differ in several key specification fields, with the most striking contrast being TDP. The V1807B consumes 45W, while the 2800H draws only 15W—a threefold difference that defines their intended use cases. Base clock speeds also differ slightly: the 2800H starts at 3.40 GHz versus 3.35 GHz for the V1807B, though both reach the same 3.80 GHz boost clock.

L3 cache capacity is another divergence. The V1807B offers 2 MB shared, while the 2800H provides 4 MB shared. Die size follows suit, with the V1807B at 210 mm² and the 2800H at 246 mm². Transistor counts are listed only for the V1807B at 4,950 million; no figure is given for the 2800H. The market segment also separates them: Desktop for the V1807B, Mobile for the 2800H. Release dates differ by about three months, with the V1807B launching on 2018-02-20 and the 2800H on 2018-05-29. Their codenames and generations are distinct—"Great Horned Owl" versus "Raven Ridge"—and they belong to the 1000 series and 2000 series respectively.

Head-to-Head Benchmarks

The V1807B wins all six benchmark comparisons, but the margins are consistently slim. In Cinebench R15 multi-core, the V1807B scores 701 against 697 for the 2800H, a 0.6% advantage. The R15 single-core test is a perfect tie at 98 points each, with a 0% delta. Moving to Cinebench R20, the V1807B leads 2921 to 2907 in multi-core (0.5%) and 412 to 410 in single-core (0.5%). The pattern holds in Cinebench R23, where the V1807B posts 6957 versus 6922 in multi-core (0.5%) and 982 versus 977 in single-core (0.5%).

The average benchmark scores reinforce this picture. The V1807B averages 2012, while the 2800H averages 2002, a 10-point gap. In context, the V1807B's nearest rival is the AMD Ryzen 7 1700 at 2015, just 0.1% faster, while the 2800H's closest competitor is the Intel Core i5-8400T at 2001, a 0% difference. Both chips sit in the same performance tier, surrounded by Intel Core i5-8300H and i5-8400H parts scoring between 2003 and 2005.

Where Each One Wins

The AMD Ryzen Embedded V1807B wins in every benchmark category where raw compute throughput is the sole criterion. Its six head-to-head victories span both multi-core and single-core workloads across Cinebench R15, R20, and R23. The largest margin is 0.6% in R15 multi-core, but even the smallest—the single-core tie at 98—shows no scenario where the 2800H pulls ahead. For workloads like video encoding, software compilation, or 3D rendering that scale across all 8 threads, the V1807B's consistent 0.5% edge in modern Cinebench versions means it will finish jobs slightly sooner, every time.

The AMD Ryzen 7 2800H wins in the power-efficiency domain, which is not captured by the Cinebench scores but is explicit in the specification data. Its 15W TDP versus 45W for the V1807B means it generates one-third the heat, requires a smaller cooler, and drains batteries slower. For passively cooled industrial PCs, thin laptops, or embedded systems in sealed enclosures, the 2800H's performance deficit—never exceeding 0.6%—is a negligible price for a massive thermal advantage. The 2800H also offers double the L3 cache at 4 MB, which could benefit workloads with high cache reuse, though the benchmark data does not isolate this effect.

In practical terms, the V1807B suits always-on desktop-class systems where power is cheap and cooling is ample. The 2800H suits portable or thermally constrained designs where 15W is a hard ceiling. The benchmark results show that if you can cool 45W, you gain almost nothing in performance; if you can only cool 15W, you lose almost nothing in performance. The choice comes down to your chassis, not your workload.
