AMD Ryzen 3 PRO 1300 vs Intel Core i5-5675C Comparison

The AMD Ryzen 3 PRO 1300 and Intel Core i5-5675C are both 4-core, 4-thread desktop processors with a 65 W TDP, yet the benchmark data shows a consistent and decisive performance gap. Across every shared Cinebench test, the Ryzen 3 PRO 1300 wins by a margin of roughly 25%, making it the clear choice for compute-heavy workloads. The Core i5-5675C, however, counters with integrated Iris Pro Graphics 6200 and DDR3 memory support, which the Ryzen lacks entirely. The data positions the Ryzen as the stronger pure-CPU part, while the Intel chip offers a more complete package for systems that need a GPU without a discrete card.

The Verdict

The benchmark results are unambiguous: the AMD Ryzen 3 PRO 1300 outperforms the Intel Core i5-5675C in every measured CPU test. The Ryzen's lead ranges from 25.1% in Cinebench R15 multi-core to 25.3% in Cinebench R23 single-core, with all intermediate tests falling in the same narrow band. This consistency suggests a fundamental architectural advantage rather than a workload-specific quirk. The Ryzen 3 PRO 1300 posts an average benchmark score of 1778 against the Intel's 1759, and both sit at the 41st percentile of all CPUs, indicating they are direct peers in the broader market.

For users prioritizing raw processing power, the Ryzen 3 PRO 1300 is the obvious selection. Its Cinebench R23 multi-core score of 6148 versus the Intel's 4912 represents a 25.2% advantage, which would translate to noticeably faster rendering, compilation, and other parallel tasks. The Ryzen also wins single-core by 25.3% in R23 (868 vs 693), so even lightly-threaded applications favor AMD. The data does not show any CPU test where the Intel chip is competitive.

The Intel Core i5-5675C, however, is not without merit. Its integrated Iris Pro Graphics 6200 is a feature completely absent from the Ryzen 3 PRO 1300, which has no iGPU listed. For a build intended to run without a discrete graphics card, the Intel part is functionally superior despite its CPU deficit. Additionally, the Intel chip supports DDR3 memory, which may be relevant for users reusing older RAM modules. The Intel part also carries a launch MSRP of $276, though the Ryzen's launch price is not listed in the data. The choice hinges on whether the user needs the integrated graphics and DDR3 compatibility or the superior CPU throughput.

Architecture Differences

The two processors come from different architectural lineages that explain their divergent performance profiles. The AMD Ryzen 3 PRO 1300 is built on the Zen architecture, using a 14 nm process at GlobalFoundries, with a die size of 213 mm² and 4,800 million transistors. The Intel Core i5-5675C uses the Broadwell architecture, also on a 14 nm process but fabricated by Intel, with a smaller die size of 182 mm² and no transistor count listed. The Ryzen's larger die and higher transistor count suggest a more complex design that may contribute to its computational advantage.

Cache hierarchies differ substantially. The Ryzen 3 PRO 1300 features 96 KB of L1 cache per core, 512 KB of L2 cache per core, and a shared 8 MB L3 cache. The Intel Core i5-5675C has 64 KB of L1 per core, 256 KB of L2 per core, and only 4 MB of shared L3. The Ryzen's doubled L3 cache and larger per-core caches likely play a role in its consistent benchmark wins, particularly in multi-threaded tests where cache efficiency matters.

Memory architecture also separates these parts. The Ryzen uses DDR4 memory with a dual-channel bus rated at 42.7 GB/s, while the Intel part uses DDR3 with dual-channel bandwidth of just 25.6 GB/s. The Ryzen's higher memory bandwidth, a 67% advantage, can feed data to the cores faster, which is critical for sustained workloads. The Ryzen also supports ECC memory, a feature absent from the Intel chip, and uses the AMD Socket AM4 platform, whereas the Intel uses Socket 1150. The Intel part includes integrated Iris Pro Graphics 6200, while the Ryzen has no iGPU listed, marking the most significant functional divergence beyond raw compute.

Specification Differences

The core and thread counts are identical at 4 cores and 4 threads, but the clock speeds tell a different story. The AMD Ryzen 3 PRO 1300 has a base clock of 3.50 GHz and a boost clock of 3.70 GHz. The Intel Core i5-5675C runs at a lower 3.10 GHz base and 3.60 GHz boost. The Ryzen's higher clocks at both ends of the spectrum align with its benchmark superiority, though the gap is modest compared to the 25% performance delta, indicating architectural efficiency also matters.

Memory support is a clear differentiator. The Ryzen supports DDR4 with a dual-channel bus and 42.7 GB/s bandwidth, plus ECC memory. The Intel supports DDR3 with dual-channel and only 25.6 GB/s bandwidth, with no ECC. This makes the Ryzen more suitable for workstation-style builds where ECC memory is required. The Intel part's memory bandwidth is roughly 40% lower, a handicap visible in memory-sensitive applications.

The integrated graphics situation is lopsided. The Intel Core i5-5675C ships with Iris Pro Graphics 6200, while the AMD Ryzen 3 PRO 1300 has no integrated graphics at all. This means the Intel chip can power a display without a discrete GPU, while the Ryzen requires a separate graphics card. The Intel part also has a PCIe Gen 3, 16 Lane (CPU only) configuration listed, while the Ryzen's PCIe details are absent from the data. The Ryzen has an unlocked multiplier, as does the Intel part, so both allow overclocking. The Intel chip has a launch MSRP of $276; the Ryzen's launch MSRP is not provided.

Head-to-Head Benchmarks

The head-to-head results are remarkable for their uniformity. In Cinebench R15 multi-core, the AMD Ryzen 3 PRO 1300 scores 619 against the Intel's 495, a 25.1% advantage. The single-core R15 test shows a nearly identical pattern: 87 vs 69, a 26.1% win for AMD. This consistency across multi-core and single-core tests suggests the Ryzen's advantage is not about core utilization but about per-core performance and memory efficiency.

Moving to Cinebench R20, the Ryzen scores 2582 in multi-core versus the Intel's 2063, a 25.2% delta. The single-core R20 test yields 364 vs 291, a 25.1% gap. The margins remain locked in the same range, reinforcing that the Ryzen's lead is structural. The most recent test, Cinebench R23, shows the Ryzen at 6148 multi-core and 868 single-core, while the Intel trails at 4912 and 693, respectively. The deltas are 25.2% and 25.3%, the largest margins recorded.

The Intel Core i5-5675C has additional Geekbench scores not present for the Ryzen, scoring 4159 multi-core and 1388 single-core. However, since the Ryzen lacks corresponding Geekbench results, these cannot be compared directly. The overall wins tally is 6 for the AMD part and 0 for the Intel part in the shared tests. This sweep is decisive, with every delta hovering around 25%, suggesting a fixed performance differential rather than workload-dependent variability.

Where Each One Wins

The AMD Ryzen 3 PRO 1300 wins every CPU benchmark where both were tested, making it the superior choice for any compute-intensive task. Its Cinebench R23 multi-core score of 6148 versus 4912 indicates a 25.2% advantage in rendering or video encoding workloads. The single-core wins, such as the 25.3% lead in R23 single-core (868 vs 693), mean the Ryzen also excels in everyday applications like web browsing, office software, and lightly-threaded games. The Ryzen's higher memory bandwidth of 42.7 GB/s and larger 8 MB L3 cache further support its lead in data-heavy workloads. For users building a desktop with a discrete GPU, the Ryzen 3 PRO 1300 is the clear winner based on the data.

The Intel Core i5-5675C wins in scenarios where its integrated Iris Pro Graphics 6200 becomes essential. Since the Ryzen has no iGPU, the Intel chip is the only option for a system that must operate without a separate graphics card. This makes it suitable for basic office PCs, media centers, or legacy builds where a discrete GPU is not feasible. The Intel part also supports DDR3 memory, which could be a deciding factor for users with existing DDR3 modules, though its 25.6 GB/s bandwidth is substantially lower than the Ryzen's DDR4 throughput. The Intel chip's launch MSRP of $276 is documented, but without a Ryzen price, no cost comparison can be made. Ultimately, the Intel Core i5-5675C wins on platform flexibility and integrated graphics, while the AMD Ryzen 3 PRO 1300 wins decisively on raw CPU performance across all six shared benchmarks.
