AMD Ryzen 3 2300X vs AMD Ryzen Embedded V1756B Comparison

Head-to-Head Benchmarks

The benchmark data paints a remarkably consistent picture. Across all six Cinebench comparisons, the AMD Ryzen Embedded V1756B wins every single test, and the margin is identical in each case: 6.6%. That uniformity is unusual. It suggests the performance gap is structural, not workload-dependent.

In Cinebench R23 multi-core, the V1756B scores 6867 against 6443 for the Ryzen 3 2300X. That is a 424-point advantage, a meaningful gap for a 4-core part. Single-core R23 tells the same story: 969 versus 909. The V1756B leads by 60 points, a 6.6% edge. The same pattern repeats in R20, where the V1756B posts 2884 multi-core and 406 single-core, while the 2300X manages 2706 and 381 respectively. Even in the older R15 test, the embedded chip leads 692 to 649 in multi-core and 97 to 91 in single-core. Every result, every generation of Cinebench, same relative outcome.

What is notable is that the 2300X has higher clock speeds on paper. Its base clock is 3.50 GHz and boost is 4.00 GHz, versus 3.25 GHz base and 3.60 GHz boost for the V1756B. Yet the V1756B still wins. The reason appears to be thread count. The V1756B has 8 threads, the 2300X has 4. Cinebench scales with thread count, and the extra logical cores give the embedded part an insurmountable lead. But even in single-core tests, where thread count should not matter, the V1756B still comes out ahead. That is counterintuitive given the 400 MHz boost disadvantage, but the recorded data is unambiguous.

The 2300X does have one additional benchmark in the database: Geekbench. It scores 3351 multi-core and 1216 single-core. There is no comparable Geekbench result for the V1756B in the data, so a direct head-to-head in that suite cannot be established. Its absence does not change the Cinebench results, but it is importantly the 2300X has at least one suite where it can demonstrate standalone performance.

Average benchmark scores confirm the overall parity in class. The V1756B averages 1986 across its recorded tests, while the 2300X averages 1968. That is a narrow 18-point gap in average terms, even though the head-to-head Cinebench results all favor the V1756B. The discrepancy exists because the 2300X includes Geekbench scores in its average, while the V1756B does not. The percentile rankings are identical: both sit at the 44th percentile of all CPUs in the database.

Architecture Differences

Both processors are built on AMD's Zen architecture, but they are not identical under the hood. The V1756B is part of the Ryzen Embedded line, using the "Great Horned Owl" generation on a 14 nm process. The 2300X is a Ryzen 3 part from the "Pinnacle Ridge" generation, also known as Zen+, built on a 12 nm process. Both are manufactured by GlobalFoundries. The process shrink is real, but the data shows it does not translate into a performance win for the 2300X in these tests.

Transistor counts are close. The V1756B packs 4,950 million transistors on a 210 mm² die. The 2300X has 4,800 million on a 213 mm² die. Essentially the same transistor density, despite the process node difference. The V1756B actually has slightly more transistors in a slightly smaller area.

Cache configuration differs in two ways. The V1756B has 128 KB of L1 per core, while the 2300X has 96 KB per core. That is a 32 KB per-core advantage for the embedded part. L2 is identical at 512 KB per core. L3 is where the 2300X pulls ahead: it has 4 MB shared, double the 2 MB shared on the V1756B. More L3 cache on the 2300X, but it still loses the benchmarks. The extra L1 on the V1756B appears to matter more in the recorded workloads.

Thread count is the biggest architectural divergence. The V1756B supports Simultaneous Multithreading, giving it 8 threads from 4 cores. The 2300X has no SMT, so it runs 4 threads on 4 cores. This is the single most important difference for multi-threaded workloads. The V1756B also integrates Radeon Vega 8 graphics, while the 2300X has no integrated graphics at all. That is a decisive feature difference for systems that need a display output without a discrete GPU.

Power and platform differ substantially. The V1756B is rated at 45W TDP and uses AMD Socket FP5, a mobile and embedded socket. The 2300X is a 65W part on AMD Socket AM4, the mainstream desktop platform. The lower TDP of the V1756B is notable given that it wins every benchmark. Memory support is DDR4 dual-channel for both, and neither supports ECC. The 2300X lists a memory bandwidth figure of 46.9 GB/s and PCIe Gen 3 with 16 lanes (CPU only). The V1756B lists no PCIe or bandwidth figures in the database.

The 2300X has an unlocked multiplier, meaning it is overclockable. The V1756B is locked. The 2300X also has a part number listed, YD230XBBM4KAFYD230XBBAFMPK, while the V1756B has no part number in the database. Both are marked as Active production status. Release dates are close: the V1756B launched on February 20, 2018, and the 2300X on September 9, 2018, roughly seven months later.

The Verdict

The data is one-sided. The AMD Ryzen Embedded V1756B wins all six head-to-head Cinebench comparisons, with a uniform 6.6% margin across both single-core and multi-core tests. If the choice is purely about raw compute performance in Cinebench workloads, the V1756B is the pick. The fact that it achieves this while drawing 45W against the 2300X's 65W makes the result more impressive. It also has integrated Radeon Vega 8 graphics, which the 2300X lacks entirely. For a system that needs graphics output without a discrete card, the V1756B is the only option of the two.

The 2300X is not without its own arguments. It has double the L3 cache, 4 MB against 2 MB. It has a higher base clock, 3.50 GHz versus 3.25 GHz, and a higher boost clock, 4.00 GHz versus 3.60 GHz. It is built on a newer 12 nm process. It has an unlocked multiplier, so it can be overclocked, which could close or reverse the gap in the hands of a user willing to push it. It uses the AM4 socket, the mainstream desktop platform with broad motherboard compatibility. And it has Geekbench scores in the database, 3351 multi-core and 1216 single-core, showing capable standalone performance.

But the recorded benchmark results favor the V1756B. The 2300X's higher clocks and larger L3 do not overcome the V1756B's thread advantage and larger L1 cache. For a builder who wants the fastest out-of-the-box Cinebench performance, the V1756B wins. For a builder on the AM4 platform who values overclocking headroom and a desktop ecosystem, the 2300X has a place. The percentile rankings are identical at 44, and the average scores are close, 1986 versus 1968, so neither chip is a class apart. The V1756B is simply the better performer in the measured tests.

It wins on integrated features, with Radeon Vega 8 graphics that the 2300X does not have. It wins on thread count, 8 threads versus 4, and on L1 cache, 128 KB per core versus 96 KB.

The AMD Ryzen 3 2300X wins on specifications that do not show up as benchmark victories. It has a higher base clock, 3.50 GHz versus 3.25 GHz. It has a higher boost clock, 4.00 GHz versus 3.60 GHz. It has double the L3 cache, 4 MB shared versus 2 MB shared. It is built on a smaller 12 nm process node. It has an unlocked multiplier for overclocking. It uses the AM4 socket, which is the mainstream desktop platform. It has a listed memory bandwidth of 46.9 GB/s and PCIe Gen 3 with 16 lanes, neither of which the V1756B has in the database. And it has Geekbench scores, 3351 multi-core and 1216 single-core, that give it a measurable presence in a suite where the V1756B has no recorded result.

The use-case split is clear. For compute-bound workloads that scale with threads, the V1756B is the winner. For builders who need integrated graphics, the V1756B is the only choice. For users on the AM4 platform who want overclocking and a more recent process node, the 2300X has the edge in platform flexibility. The 2300X also has the higher clock ceiling, which could matter in lightly threaded tasks if overclocked, though the stock single-core results do not show it winning.
