AMD Ryzen Embedded R1305G vs Intel Core i5-4258U Comparison

The data shows a clear and consistent victory for the AMD Ryzen Embedded R1305G across all recorded multi-threaded and single-threaded workloads. Despite the Intel Core i5-4258U having a higher base clock speed of 2.40 GHz compared to 1.50 GHz, the AMD processor delivers a decisive performance advantage in every Cinebench test. The benchmark results indicate that the Ryzen Embedded R1305G is the faster part in this comparison.

Head-to-Head Benchmarks

The AMD Ryzen Embedded R1305G wins all five head-to-head benchmark comparisons. In Cinebench R15 multicore, the AMD processor scores 269 points against 222 points for the Intel Core i5-4258U, a lead of 21.2%. This pattern repeats in Cinebench R20 multicore where the AMD scores 1121 against 929, a 20.7% advantage, and again in Cinebench R23 multicore with 2670 against 2213, another 20.7% lead. The consistency is notable: all three multicore tests show the AMD part holding a margin between 20.7% and 21.2%.

Single-threaded performance tells the same story. In Cinebench R20 singlecore, the Ryzen Embedded R1305G scores 158 versus 131 for the Intel, a 20.6% win. In Cinebench R23 singlecore, the AMD scores 377 versus 312, a 20.8% advantage. The uniformity of these deltas, all hovering around 20-21%, suggests the performance gap is structural rather than workload-specific. The AMD processor is not merely ahead in one type of test; it is ahead by nearly the same margin across the entire benchmark suite.

The Intel part does have an additional Geekbench result recorded in the database, scoring 1664 in multicore and 844 in singlecore. However, there is no corresponding Geekbench score for the AMD processor in this dataset, so a direct comparison on that specific test cannot be made. The available evidence, based entirely on the shared Cinebench workloads, shows a dominant performance profile for the AMD Ryzen Embedded R1305G.

Where Each One Wins

The AMD Ryzen Embedded R1305G wins in both multithreaded and single-threaded Cinebench workloads. For users whose tasks rely on Cinebench-style rendering and CPU compute, the AMD part is the clear choice. Its 20.7% lead in Cinebench R23 multicore means faster completion of heavily threaded render jobs, and its 20.8% lead in singlecore indicates snappier response in lightly threaded applications.

There are no benchmark categories where the Intel Core i5-4258U wins in this dataset. The Intel processor's recorded wins count is zero. While the Intel part has a higher base clock of 2.40 GHz and a boost clock of 2.90 GHz against the AMD's 1.50 GHz base and 2.80 GHz boost, those clock advantages do not translate into a single benchmark victory in the recorded measurements.

The Intel Core i5-4258U sits at the same 24th percentile as the AMD Ryzen Embedded R1305G in the overall CPU rankings. The AMD's average benchmark score is 919, while the Intel's average is 902. The AMD is 0.2% ahead of the AMD Athlon Silver 3050U and 0.5% ahead of the Intel Pentium Gold G6405T among its nearest rivals. The Intel Core i5-4258U is 0.1% behind the Intel Core i5-5350U and 0.7% behind the Intel Core i3-4330T in its own rival group. These figures place both processors in a similar performance tier, but the direct head-to-head data favors the AMD part.

Architecture Differences

The two processors come from different architectural generations and manufacturing processes. The AMD Ryzen Embedded R1305G uses the Zen architecture, built on a 14 nm process at GlobalFoundries. It contains 3,500 million transistors on a 148 mm² die. The Intel Core i5-4258U uses the older Haswell architecture, built on a 22 nm process at Intel, with 1,400 million transistors on a 118 mm² die. The newer process node gives the AMD part a transistor density advantage.

Cache configurations differ as well. The AMD Ryzen Embedded R1305G has 96 KB of L1 cache per core and 512 KB of L2 cache per core, with 4 MB of shared L3 cache. The Intel Core i5-4258U has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 3 MB of shared L3 cache. The AMD part offers more cache at every level. Both processors have 2 cores and 4 threads.

Memory support also differs. The AMD Ryzen Embedded R1305G supports DDR4 memory with a dual-channel bus and a memory bandwidth of 38.4 GB/s. The Intel Core i5-4258U supports DDR3 memory, and the database records no memory bus width or bandwidth figure for it. Neither processor supports ECC memory. The AMD part uses 8 PCIe Gen 3 lanes, while the database records no PCIe specification for the Intel part.

The integrated graphics units are also different. The AMD Ryzen Embedded R1305G includes a Radeon Vega 3, while the Intel Core i5-4258U includes an Intel HD 5100. Both are mobile market segment processors. The AMD has a TDP of 10 watts, while the Intel has a TDP of 28 watts. The AMD processor is listed as active in production, while the Intel processor's production status is not recorded. The AMD was released on 2020-02-24, while the Intel was released on 2013-06-03, making the Intel part roughly seven years older.

The Verdict

The AMD Ryzen Embedded R1305G is the faster processor in every recorded benchmark. It wins all five Cinebench tests with margins between 20.6% and 21.2%. The data does not show a single workload in which the Intel Core i5-4258U comes out ahead. For any user prioritizing raw CPU performance in Cinebench-based workloads, the AMD part is the correct choice.

The Intel Core i5-4258U offers a higher base clock of 2.40 GHz, but that advantage does not appear in the recorded scores. The AMD part, despite its lower 1.50 GHz base clock, delivers a 20.7% higher multicore score in Cinebench R23. The AMD's architectural advantages, including the newer 14 nm Zen design, larger cache hierarchy, and more modern DDR4 memory support, are reflected in the benchmark results.

The AMD Ryzen Embedded R1305G also operates at a lower TDP of 10 watts versus 28 watts for the Intel part. This means the faster processor in this comparison also carries a lower thermal design power. The AMD part is active in production, while the Intel part's production status is not recorded. The verdict from the data is straightforward: the AMD Ryzen Embedded R1305G outperforms the Intel Core i5-4258U across the board, and it does so with lower power consumption and a more modern feature set.
