AMD Ryzen Embedded V1756B vs AMD Ryzen Embedded V1807B Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD Ryzen Embedded V1807B across every benchmark in the comparison. The V1807B wins all six head-to-head tests, with the V1756B taking zero wins. The margins are consistent, ranging from 1.0% to 1.5%, which is a narrow but uniform advantage.

In Cinebench R15 multicore, the V1807B scores 701 against 692 for the V1756B, a 1.3% lead. The single-core result in the same test is 98 versus 97, a 1.0% edge. Moving to Cinebench R20, the multicore gap remains at 1.3% (2921 vs 2884), while the single-core delta widens slightly to 1.5% (412 vs 406). The Cinebench R23 results follow the same pattern: multicore is 6957 vs 6867 (1.3% ahead), and single-core is 982 vs 969 (1.3% ahead).

The largest relative victory for the V1807B comes in Cinebench R20 single-core, where it leads by 1.5%. The smallest margin is in Cinebench R15 single-core at 1.0%. Across all six tests, the average advantage is roughly 1.3%, which is a modest but consistent performance differentiation.

The average benchmark score for the V1807B is 2012, placing it in the 45th percentile of all CPUs in the database. The V1756B averages 1986, sitting at the 44th percentile. That one-percentile gap reflects the slim but real performance separation between the two parts.

When compared to nearest rivals, the V1807B sits within 0.4% of the Intel Core i5-8400H (2003) and 0.4% of the Intel Xeon D-1712TR (2004). The AMD Ryzen 7 1700 is essentially tied at 2015, just 0.1% ahead. The V1756B, by contrast, matches the Intel Core i5-8279U at 1987 (0.0% delta), trails the Intel Xeon E3-1585L v5 by 0.2% (1989), and sits 0.3% behind the AMD Ryzen 5 1500X (1992). These rival comparisons show both chips landing in the same performance tier, with the V1807B holding a slight edge over the V1756B.

The Verdict

The data is unambiguous: the AMD Ryzen Embedded V1807B is the faster processor in every measured workload. If the choice is purely about peak performance, the V1807B is the correct pick. All six benchmark wins go to the V1807B, and the average benchmark score is 1.3% higher (2012 vs 1986).

However, the practical difference is small. A 1.0% to 1.5% lead across Cinebench tests will not be noticeable in most real-world tasks. Both chips share the same core and thread counts, the same 45 W TDP, and the same socket. The V1807B is the better part for anyone who wants the maximum available performance from this platform, especially in single-threaded tasks where the 1.5% R20 single-core lead is the largest gap.

For users who prioritize the integrated graphics, the V1807B also holds an advantage: it carries the Radeon RX Vega 11 iGPU, while the V1756B uses the Radeon Vega 8. That difference is not reflected in the CPU benchmarks, but it is a meaningful spec-level distinction for systems relying on the integrated graphics.

The V1756B is not a bad choice; it is simply the slower sibling. Its benchmark scores are only marginally behind, and its nearest rival comparison shows it performing essentially identically to an Intel Core i5-8279U. If the V1807B is unavailable or if the system design favors the V1756B for any reason, the performance penalty is minor. But strictly from the recorded data, the V1807B wins on every count.

Architecture Differences

Both processors are built on the same Zen architecture, codenamed Zen (Great Horned Owl), and belong to the Ryzen Embedded 1000 series. They share the same 14 nm process node from GlobalFoundries, the same 4,950 million transistor count, and the same 210 mm² die size. The socket is identical: AMD Socket FP5. Both have 4 cores and 8 threads, and both are unlocked disabled (the multiplier is not unlocked).

The cache hierarchy is also identical. Each core has 128 KB of L1 cache and 512 KB of L2 cache, with a shared 2 MB L3 cache. Memory support is DDR4 over a dual-channel bus, and neither chip supports ECC memory. The production status for both is Active, and both were released on the same date: 2018-02-20.

The key architectural difference lies in clock speeds and the integrated graphics. The V1807B has a base clock of 3.35 GHz and a boost clock of 3.80 GHz. The V1756B runs at 3.25 GHz base and 3.60 GHz boost. That 100 MHz to 200 MHz gap directly explains the benchmark deltas. The V1807B also integrates a Radeon RX Vega 11 GPU, while the V1756B uses a Radeon Vega 8. Both parts have a 45 W TDP, and neither has a listed PCIe configuration in the database.

There are no other architectural divergences. The process node, transistor count, die size, cache layout, memory controller, and socket are all shared. This is a straightforward binning situation: the V1807B is the higher-clocked, higher-performing variant, and the V1756B is the slightly lower-clocked version with a less capable iGPU.

FAQ

Where Each One Wins

The AMD Ryzen Embedded V1807B wins every category in the recorded data. It takes all six head-to-head benchmark tests, covering both single-core and multi-core workloads across Cinebench R15, R20, and R23. Its average benchmark score of 2012 is higher than the V1756B's 1986. It also holds a higher percentile ranking (45th vs 44th) among all CPUs in the database.

The V1807B's advantages extend beyond raw CPU benchmarks. It features a Radeon RX Vega 11 integrated GPU, which is a more capable graphics solution than the Radeon Vega 8 found in the V1756B. For systems that rely on the iGPU for display output or light graphics work, this is a meaningful differentiator.

The V1756B does not win any benchmark in the comparison. Its sole redeeming feature is that it is close: the largest gap is 1.5%, and the average delta is only 1.3%. In a system where the V1807B is not available or where the slightly lower clocks are acceptable, the V1756B will deliver nearly identical CPU performance. Its nearest rival comparisons show it performing on par with an Intel Core i5-8279U, which is a respectable result.

For use cases that demand maximum CPU throughput, the V1807B is the clear pick. For tasks that are heavily single-threaded, the V1807B again leads, with the largest single-core margin in Cinebench R20. For systems that need better integrated graphics, the V1807B's Radeon RX Vega 11 is the stronger option. There is no workload in the database where the V1756B comes out on top.

Specification Differences

The two processors share most of their specifications, but there are four fields where they differ. The most important is clock speed: the V1807B runs at 3.35 GHz base and 3.80 GHz boost, while the V1756B runs at 3.25 GHz base and 3.60 GHz boost. The V1807B also has a different integrated GPU: Radeon RX Vega 11 versus Radeon Vega 8.

The benchmark results differ as a consequence of the clock speeds. The V1807B scores higher in all six Cinebench tests, with deltas ranging from 1.0% to 1.5%. The average benchmark score is 2012 for the V1807B and 1986 for the V1756B. The percentile ranking is 45 for the V1807B and 44 for the V1756B.

All other specifications are identical. Both have 4 cores, 8 threads, a 45 W TDP, AMD Socket FP5, Zen architecture, 14 nm process node, 4,950 million transistors, and a 210 mm² die size. The cache is the same: 128 KB L1 per core, 512 KB L2 per core, and 2 MB shared L3. Both support DDR4 memory over a dual-channel bus, and neither supports ECC. Neither has an unlocked multiplier. Both were released on 2018-02-20 and are marked as Active in production. The launch MSRP is not listed for either part.
