AMD Ryzen Embedded R1305G vs Intel Core i3-8145U Comparison

Head-to-Head Benchmarks

The recorded data shows a clear and consistent pattern across all five shared Cinebench tests: the Intel Core i3-8145U wins every single head-to-head matchup. The AMD Ryzen Embedded R1305G does not claim a single benchmark victory in the database, with a final win tally of 0 for AMD and 5 for Intel.

Starting with multi-core performance, the Intel part leads by the same margin in every iteration of the test. In Cinebench R15 multi-core, the Intel Core i3-8145U scores 322 against 269 for the AMD Ryzen Embedded R1305G, a deficit of 16.5% for AMD. That exact delta repeats in Cinebench R20 multi-core, where Intel posts 1342 and AMD posts 1121. The R23 multi-core test shows the same story: Intel at 3196, AMD at 2670, again a 16.5% gap. This consistency across three different Cinebench versions strongly suggests the performance ratio is stable under sustained multi-threaded load, not a single-test anomaly.

Single-core results follow nearly the identical pattern. In Cinebench R20 single-core, the Intel Core i3-8145U scores 189, while the AMD Ryzen Embedded R1305G manages 158, a 16.4% difference. Cinebench R23 single-core shows Intel at 451 and AMD at 377, again 16.4% behind. The database does not include a Cinebench R15 single-core result for the AMD part, so that comparison cannot be made directly, but the two available single-core tests align closely with the multi-core deltas.

What stands out is the uniformity of the margin. Whether the workload is single-threaded or multi-threaded, and regardless of which Cinebench generation is used, the Intel part sits roughly 16.5% ahead. This is not a case where one chip wins in one scenario and loses in another; the relative performance is essentially flat across all measured conditions. For the AMD Ryzen Embedded R1305G, the average benchmark score in the database is 919, placing it at the 24th percentile of all CPUs. The Intel Core i3-8145U averages 941, landing at the 25th percentile. The two chips occupy nearly the same overall standing in the broader CPU landscape, yet in direct comparison the Intel part consistently comes out on top.

The nearest rivals for each processor reinforce this positioning. The AMD Ryzen Embedded R1305G sits within 0.5% of the AMD PRO A10-9700E, AMD Athlon Silver 3050U, AMD FX-4320, and Intel Pentium Gold G6405T. The Intel Core i3-8145U sits within 0.4% of the Intel Core i7-2715QE, AMD Athlon X4 860K, Intel Core i5-4330M, and AMD A8-7670K. In both cases the competition is tight, but the Intel part's surrounding rivals have slightly higher average scores than the AMD part's rivals, matching the small but real gap between the two processors themselves.

The Verdict

The data points to one straightforward conclusion: the Intel Core i3-8145U is the stronger performer in every measured benchmark. The 16.5% multi-core and 16.4% single-core advantages are consistent across Cinebench R15, R20, and R23, leaving no scenario in the database where the AMD Ryzen Embedded R1305G takes the lead. The average benchmark score confirms this, with Intel at 941 versus AMD at 919.

For a buyer choosing strictly on benchmark performance, the Intel Core i3-8145U is the clear pick. It delivers higher scores in both single-threaded and multi-threaded workloads, and those gains are uniform rather than workload-specific. The AMD part is not without merit, however. It carries a lower TDP of 10 watts against Intel's 15 watts, which could matter in thermally constrained designs, but the recorded performance data does not show any offsetting advantage. The Intel part also remains in active production status, while the AMD part is listed as active as well, so availability is not a differentiator.

The percentile standings are nearly identical, 24th for AMD and 25th for Intel, meaning both chips sit in the same general tier of the CPU market. But within that tier, the Intel processor is measurably faster. If the selection criteria are purely about compute performance from the database, the Intel Core i3-8145U wins without qualification.

Specification Differences

The two processors differ on several core specifications. The AMD Ryzen Embedded R1305G has a base clock of 1500.00 MHz and a boost clock of 2.80 GHz. The Intel Core i3-8145U has a base clock of 2.10 GHz and a boost clock of 3.90 GHz, making it faster in both clock states. Thermal design power also differs: AMD is rated at 10 watts, Intel at 15 watts. The AMD part uses AMD Socket FP5, while the Intel part uses Intel BGA 1528. The Intel part has a recorded launch MSRP of $281; the AMD part has no launch MSRP in the database.

Process technology differs as well. AMD uses a 14 nm node from GlobalFoundries, with 3,500 million transistors on a 148 mm² die. Intel uses a 10 nm node from its own foundry, with transistor count and die size not recorded. PCIe lane counts differ: AMD provides Gen 3 with 8 lanes (CPU only), while Intel provides Gen 3 with 16 lanes (CPU only). Cache hierarchies are not identical. AMD has 96 KB L1 per core and 512 KB L2 per core, while Intel has 64 KB L1 per core and 256 KB L2 per core. Both share 4 MB L3 cache. The integrated graphics differ: AMD uses Radeon Vega 3, Intel uses UHD Graphics 620. Release dates are separate, with AMD launching on 2020-02-24 and Intel on 2018-09-30. Neither processor has an unlocked multiplier.

Architecture Differences

The AMD Ryzen Embedded R1305G is built on the Zen architecture, specifically the Ryzen Embedded (Zen, Banded Kestrel) generation. It uses a 14 nm process from GlobalFoundries. The Intel Core i3-8145U is built on the Whiskey Lake architecture, specifically Whiskey Lake-U, using a 10 nm process from Intel. Both are dual-core, quad-thread designs, but the underlying microarchitectures come from different design philosophies and manufacturing generations.

The cache layouts reflect these architectural choices. AMD allocates 96 KB of L1 cache per core and 512 KB of L2 per core, which is larger than Intel's 64 KB L1 and 256 KB L2 per core. Both chips share 4 MB of L3 cache, so the total L3 capacity is equal. The larger per-core L1 and L2 on the AMD side does not translate into a benchmark advantage in the recorded data, as the Intel part wins all tests despite having smaller per-core caches.

The transistor counts also differ. AMD's 14 nm die contains 3,500 million transistors on a 148 mm² area. Intel's transistor count and die size are not recorded, but the 10 nm process node is the key architectural distinction. The AMD part is fabricated by GlobalFoundries, while Intel fabricates its own silicon. The integrated graphics solutions are architecturally distinct as well: AMD pairs the CPU with Radeon Vega 3, while Intel pairs it with UHD Graphics 620. Both support DDR4 memory in dual-channel mode with identical 38.4 GB/s bandwidth, and neither supports ECC.

The production status also differs. The AMD Ryzen Embedded R1305G is listed as active, while the Intel Core i3-8145U is listed as end-of-life. This matters for long-term supply planning, though the benchmark data shows no performance consequence.

Where Each One Wins

The Intel Core i3-8145U wins every benchmark category in the database. In multi-core workloads, it leads by 16.5% consistently across Cinebench R15, R20, and R23. In single-core workloads, it leads by 16.4% in both available Cinebench R20 and R23 tests. The Intel part also has a higher average benchmark score, 941 versus 919, and a higher percentile ranking, 25th versus 24th. Any workload that stresses either single-threaded performance or multi-threaded throughput will favor the Intel processor.

The AMD Ryzen Embedded R1305G does not win any recorded benchmark, so there is no performance category where it is the superior choice based on the data. Its advantages are not measured in compute performance. The AMD part has a lower TDP of 10 watts compared to Intel's 15 watts, which could make it preferable in power-constrained or passively cooled designs. It also uses a socketed AMD FP5 package, which may offer different board-level flexibility than Intel's BGA 1528. The AMD part has a more recent release date and remains in active production, while the Intel part is end-of-life. The AMD part also has larger per-core L1 and L2 caches, though this does not produce a measurable benchmark advantage.

For use cases focused on raw CPU throughput, the Intel Core i3-8145U is the only choice supported by the data. For use cases where lower power draw, newer availability, or socket compatibility take priority over benchmark scores, the AMD Ryzen Embedded R1305G has qualitative appeal, but the database shows no performance scenario where it comes out ahead. The decision reduces to whether the 10-watt TDP and active production status of the AMD part outweigh the Intel part's consistent 16.5% performance lead.
