AMD Ryzen 5 4500U vs AMD Ryzen Embedded V1807B Comparison

Where Each One Wins

The benchmark data splits these two processors along clean lines. The AMD Ryzen 5 4500U takes three of the four head-to-head tests, while the AMD Ryzen Embedded V1807B claims one decisive victory.

The Ryzen 5 4500U dominates in single-threaded workloads. Its Cinebench R15 single-core score of 174 crushes the Embedded V1807B's 98, a 77.6% advantage. That gap narrows in Cinebench R23 single-core, where the 4500U scores 1152 against the V1807B's 982, a 17.3% lead. For everyday responsiveness, web browsing, and lightly threaded applications, the mobile chip is clearly the stronger option.

The 4500U also wins the older Cinebench R15 multi-core test. It scores 892 versus the V1807B's 701, a 27.2% margin. This test favors the 4500U's six physical cores, even though the V1807B has eight threads via simultaneous multithreading. The 4500U's newer Zen 2 architecture appears to deliver more work per clock in this workload.

The Embedded V1807B strikes back in Cinebench R23 multi-core. It scores 6957, beating the 4500U's 5920 by 14.9%. This is a substantial reversal. The V1807B's higher base clock of 3.35 GHz, combined with its eight threads, lets it pull ahead in a sustained, fully threaded render. The 4500U's 15-watt TDP and lower 2.30 GHz base clock likely cap its sustained multi-threaded throughput.

The overall average benchmark scores are nearly identical. The 4500U averages 2035, while the V1807B averages 2012. Both sit at the 45th percentile among all CPUs in the database. The nearest rivals confirm this parity: the 4500U trades blows with the Intel Xeon E-2124G (0.1% ahead), the Intel Core i7-3960X (0.1% behind), and the AMD Opteron 6386 SE (0.1% behind). The V1807B sits equally close to the AMD Ryzen 7 1700 (0.1% behind) and the Intel Core i5-8300H (0.3% ahead).

In short, the 4500U wins where responsiveness and short bursts matter. The V1807B wins where sustained parallel number crunching matters. Neither chip is a runaway winner overall.

The Verdict

Choose the AMD Ryzen 5 4500U if your priority is single-threaded speed and efficiency. The data shows it leads by 77.6% in Cinebench R15 single-core and by 17.3% in Cinebench R23 single-core. It also wins the older multi-core test by 27.2%. Its six cores and Zen 2 architecture make it the better general-purpose processor for interactive use, and its 15-watt TDP makes it suitable for thin, light laptops.

Choose the AMD Ryzen Embedded V1807B if you need maximum sustained multi-threaded throughput. Its Cinebench R23 multi-core score of 6957 is the single highest benchmark result recorded for either chip. The V1807B's four cores and eight threads, boosted by a 3.35 GHz base clock, allow it to outmuscle the 4500U in longer render workloads. Its 45-watt TDP and desktop-class positioning reflect a design for always-on embedded systems rather than battery-powered mobility.

The parity in average scores (2035 versus 2012) means neither chip is a bad choice. The 4500U is the more balanced daily driver. The V1807B is the more specialized workhorse for threaded tasks. The production status of both processors is listed as Active, so both remain available for new designs.

Head-to-Head Benchmarks

The four recorded head-to-head tests paint a nuanced picture. The largest margin belongs to the Ryzen 5 4500U in Cinebench R15 single-core. Its score of 174 is 77.6% higher than the V1807B's 98. This is a massive gap, reflecting the generational leap from Zen to Zen 2 and the 4500U's higher 4.00 GHz boost clock.

The second-largest margin, 27.2%, also favors the 4500U in Cinebench R15 multi-core. The 4500U scores 892, while the V1807B manages 701. This test, released in 2013, appears to scale better with the 4500U's six physical cores than with the V1807B's four cores and eight threads.

The V1807B's only win is Cinebench R23 multi-core, and it is decisive. The V1807B scores 6957, beating the 4500U's 5920 by 14.9%. This is the most modern and demanding multi-threaded test in the set. The V1807B's higher base clock of 3.35 GHz, compared with the 4500U's 2.30 GHz, likely explains why it sustains better throughput when all cores are loaded for an extended period.

The final test, Cinebench R23 single-core, goes to the 4500U by a 17.3% margin (1152 versus 982). This confirms that the 4500U's architectural advantage persists even in a newer test, though the gap narrows compared with the R15 version.

The win count is 3-1 in favor of the 4500U. However, the V1807B's R23 multi-core victory is significant because that test is the most representative of modern render workloads. If your application is built around Cinebench R23-style parallelism, the V1807B is the stronger choice despite losing three of four tests.

Architecture Differences

The two chips come from different generations and foundries. The Ryzen 5 4500U is a Zen 2 design codenamed Renoir, built on TSMC's 7 nm process. The Ryzen Embedded V1807B is a first-generation Zen design codenamed Great Horned Owl, built on GlobalFoundries' 14 nm process. This generational gap explains much of the performance split.

The transistor counts differ dramatically. The 4500U packs 9,800 million transistors into a 156 mm² die. The V1807B contains 4,950 million transistors spread across a larger 210 mm² die. The 7 nm process allows the 4500U to fit nearly twice as many transistors into a smaller area.

Cache configurations also diverge. The 4500U provides 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 8 MB of shared L3 cache. The V1807B provides 128 KB of L1 cache per core, 512 KB of L2 cache per core, but only 2 MB of shared L3 cache. The 4500U's four times larger L3 cache is a significant advantage for workloads that reuse data.

Clock speeds tell a different story. The 4500U has a base clock of 2.30 GHz and a boost clock of 4.00 GHz. The V1807B has a base clock of 3.35 GHz and a boost clock of 3.80 GHz. The V1807B starts much higher but peaks lower, reflecting its higher 45-watt TDP and older architecture.

Memory support is similar but not identical. Both support DDR4 in a dual-channel configuration. The 4500U additionally supports LPDDR4 and achieves a memory bandwidth of 51.2 GB/s. The V1807B's memory bandwidth is not recorded in the database. Neither chip supports ECC memory.

The sockets differ: the 4500U uses AMD Socket FP6, while the V1807B uses AMD Socket FP5. The 4500U supports PCIe Gen 3 with 12 lanes from the CPU. The V1807B's PCIe configuration is not recorded. The 4500U targets the mobile segment, while the V1807B targets desktop embedded systems.

The release dates are about two years apart. The V1807B launched in February 2018, while the 4500U launched in January 2020. The 4500U belongs to AMD's 4000 series, while the V1807B belongs to the 1000 series. Both processors have locked multipliers, meaning they are not unlocked for overclocking.
