Architecture Differences

The two processors come from different architectural lineages, which explains several of their measured differences. The AMD Ryzen Embedded V1807B is built on the Zen architecture, also known by the codename “Great Horned Owl,” and belongs to the Ryzen Embedded 1000 series. It is manufactured by GlobalFoundries on a 14 nm process node, with a die size of 210 mm² and 4,950 million transistors. The Intel Core i5-8279U, in contrast, uses the Coffee Lake architecture, specifically Coffee Lake-U, and is part of the Core i5 generation. Intel produces this chip on its own 14 nm process node, with a smaller die size of 126 mm² and 2,300 million transistors.

Cache organization differs significantly between the two. The AMD processor allocates 128 KB of L1 cache per core and 512 KB of L2 cache per core, with a shared 2 MB L3 cache. The Intel processor has 64 KB of L1 cache per core and 256 KB of L2 cache per core, but it compensates with a larger shared 6 MB L3 cache. This means the Intel chip has three times the L3 cache of the AMD chip, which can be beneficial for workloads that repeatedly access a working set of data.

Memory support is similar in terms of type and channel configuration: both support DDR4 memory in a dual-channel layout. The Intel Core i5-8279U lists a memory bandwidth of 34.1 GB/s, while the AMD chip does not have a recorded bandwidth figure in the database. Neither processor supports ECC memory. The Intel chip also explicitly lists PCIe support as Gen 3 with 16 lanes (CPU only), while the AMD chip has no recorded PCIe specification.

The integrated graphics differ as well. The AMD Ryzen Embedded V1807B includes Radeon RX Vega 11 graphics, while the Intel Core i5-8279U features Iris Pro Plus 655. Socket types are distinct: the AMD chip uses AMD Socket FP5, and the Intel chip uses Intel BGA 1526. Production status also separates them: the AMD chip is listed as Active, while the Intel chip is End-of-life. The AMD chip was released in February 2018, and the Intel chip was released in April 2019.

Head-to-Head Benchmarks

The database records six head-to-head comparisons between these two processors, all from the Cinebench suite. In every single test, the AMD Ryzen Embedded V1807B comes out ahead, and the margins are remarkably consistent.

Starting with multi-core performance, the AMD chip scores 701 points in Cinebench R15 multicore, while the Intel chip scores 634 points. This gives the AMD processor a 10.6% advantage. In Cinebench R20 multicore, the AMD chip scores 2921 points versus 2643 points for the Intel chip, a 10.5% lead. The gap persists in Cinebench R23 multicore, where the AMD chip scores 6957 points and the Intel chip scores 6294 points, again a 10.5% difference.

Single-core results follow the same pattern. In Cinebench R15 single-core, the AMD chip scores 98 points, and the Intel chip scores 89 points, a 10.1% lead for AMD. In Cinebench R20 single-core, the AMD chip scores 412 points versus 372 points, a 10.8% advantage. Finally, in Cinebench R23 single-core, the AMD chip scores 982 points, and the Intel chip scores 888 points, a 10.6% lead.

These results indicate that the AMD processor holds a consistent edge across all recorded Cinebench versions, whether the workload is heavily threaded or single-threaded. The Intel chip, despite its higher boost clock of 4.10 GHz, does not translate that clock advantage into a win in any of these tests. The database also includes Geekbench scores for the Intel chip (3764 multicore, 1209 single-core), but no corresponding Geekbench scores are recorded for the AMD chip, so a direct comparison is not possible for that benchmark.

The overall win count is clear: the AMD Ryzen Embedded V1807B wins 6 out of 6 head-to-head tests, and the Intel Core i5-8279U wins none.

The Verdict

Based strictly on the recorded benchmark data, the AMD Ryzen Embedded V1807B is the faster processor for CPU compute workloads. It outperforms the Intel Core i5-8279U in every Cinebench test, with margins between 10.1% and 10.8%. The AMD chip’s average benchmark score of 2012 also edges out the Intel chip’s average of 1987, a difference of about 1.3%. In terms of percentile ranking among all CPUs, the AMD chip sits at the 45th percentile, while the Intel chip sits at the 44th percentile, indicating they are very close in overall standing.

The Intel Core i5-8279U does have a lower TDP of 28 W compared to the AMD chip’s 45 W, which suggests it may be better suited for thermally constrained environments. It also has a larger L3 cache (6 MB versus 2 MB) and a higher boost clock (4.10 GHz versus 3.80 GHz). However, none of these advantages produce a win in the recorded benchmarks.

For users who prioritize raw CPU performance, the data points clearly to the AMD Ryzen Embedded V1807B. For users who require a smaller thermal envelope or a mobile-oriented package, the Intel chip remains a viable option, but it will deliver lower Cinebench scores. The Intel chip also has a recorded launch MSRP of $320, while the AMD chip has no launch MSRP listed in the database.

Where Each One Wins

The AMD Ryzen Embedded V1807B wins in every recorded benchmark category. Its strengths are apparent in multi-threaded workloads, as shown by the Cinebench R15, R20, and R23 multicore tests, where it leads by 10.5% to 10.6%. It also wins in single-threaded tests, with leads of 10.1% to 10.8%. This makes it the stronger choice for applications that rely on CPU compute, such as rendering, compilation, or scientific calculations, based on the data available.

The Intel Core i5-8279U wins in efficiency and design characteristics. Its 28 W TDP is significantly lower than the AMD chip’s 45 W, which means it can fit into thinner or more thermally limited systems. Its 6 MB L3 cache is three times larger than the AMD chip’s 2 MB, which could help in workloads that are cache-sensitive, although the recorded benchmarks do not reflect a performance benefit. Its higher boost clock of 4.10 GHz is also notable, but it does not lead to a win in any of the recorded Cinebench tests. The Intel chip also has a defined memory bandwidth of 34.1 GB/s and explicit PCIe Gen 3 support, which may be relevant for system integration decisions.

In summary, the AMD processor is the performance winner across all measured CPU tests, while the Intel processor offers lower power consumption and a larger cache pool. The choice between them depends on whether the user prioritizes raw compute performance or thermal efficiency, based on the recorded specifications and benchmarks.
