AMD Ryzen 3 2300U vs Intel Core i5-5250U Comparison

Head-to-Head Benchmarks

The benchmark database records three direct head-to-head comparisons between the Intel Core i5-5250U and the AMD Ryzen 3 2300U. The results are decisive, with AMD taking two of the three matchups, but the margins tell a more nuanced story than the raw win count suggests.

In Cinebench R15 multi-core, the AMD Ryzen 3 2300U posts a score of 422.5 against the Intel Core i5-5250U's 209. That represents a 50.5% deficit for Intel, meaning the AMD part is more than twice as fast in this heavily threaded rendering workload. This is the largest performance gap recorded in the database between the two processors, and it reflects the fundamental core-count disparity: the Ryzen 3 2300U brings four physical cores to the fight, while the i5-5250U must rely on two cores with Hyper-Threading.

Geekbench multi-core tells a similar story, though with a slightly tighter margin. The AMD Ryzen 3 2300U scores 2234, while the Intel Core i5-5250U manages 1587. The delta here is 29%, meaning AMD holds a substantial but less overwhelming lead in this broader system-level benchmark. Still, a 29% advantage in multi-threaded performance is significant for two mobile processors with identical 15 W TDP ratings.

The single-core results flip the script. In Geekbench single-core, the Intel Core i5-5250U scores 825, edging out the AMD Ryzen 3 2300U's 783. The 5.4% delta favors Intel, showing that the older Broadwell architecture retains a genuine advantage in lightly threaded, latency-sensitive workloads. This is not a token win; it is a measurable lead in the exact scenario where clock speed and per-core efficiency matter most.

Interestingly, the Cinebench R15 single-core benchmark is not present in the head-to-head data. The database does list a score of 79 for the AMD Ryzen 3 2300U in that test, but no corresponding Intel score is recorded, so a direct comparison cannot be drawn. The Geekbench single-core result stands as the sole single-threaded head-to-head metric, and it belongs to Intel.

The average benchmark scores in the database place these two processors remarkably close overall. The Intel Core i5-5250U averages 856 across all recorded tests, while the AMD Ryzen 3 2300U averages 880. That is a 2.8% difference in favor of AMD, a margin that feels small given the 50.5% blowout in Cinebench R15 multi-core. The explanation lies in the test mix: the Intel part has more recorded single-core and Cinebench R20/R23 results, which pull its average up, while the AMD part's multi-core dominance is diluted by fewer data points. Both processors sit at the 23rd percentile among all CPUs in the database, meaning they occupy essentially the same tier of overall performance.

Architecture Differences

The architectural gap between these two mobile processors is wide, spanning not just years but entirely different design philosophies. The Intel Core i5-5250U is built on the Broadwell architecture, specifically the Broadwell-U codename, and belongs to the Core i5 (Broadwell-U) generation. It uses a 14 nm process node manufactured by Intel, with 1,900 million transistors packed into a 133 mm² die. In contrast, the AMD Ryzen 3 2300U is based on the Zen architecture under the Raven Ridge codename, part of the Ryzen 3 (Zen (Raven Ridge)) generation. It also uses a 14 nm process, but fabricated by GlobalFoundries, and the die is substantially larger at 210 mm² with 4,950 million transistors.

The core configuration is where the biggest functional difference emerges. The Intel part offers 2 cores and 4 threads, relying on Hyper-Threading to simulate additional execution resources. The AMD part provides 4 physical cores and 4 threads, with no SMT support. This means the Ryzen 3 2300U has double the physical execution units, which directly explains its massive lead in multi-threaded benchmarks. The clock speeds also favor AMD: the Ryzen 3 2300U runs at a 2.00 GHz base clock and boosts to 3.40 GHz, while the i5-5250U operates at a 1.60 GHz base and 2.70 GHz boost. Both are rated at 15 W TDP, making the AMD part's higher clocks and extra cores all the more impressive from a power efficiency standpoint.

Cache hierarchies differ as well. The Intel Core i5-5250U has 64 KB of L1 cache per core, 256 KB of L2 per core, and 3 MB of shared L3 cache. The AMD Ryzen 3 2300U offers 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. In every category, the AMD part has more cache, which helps feed its four cores and sustain higher throughput in cache-sensitive workloads.

Memory support also diverges sharply. The Intel processor supports DDR3 memory over a dual-channel bus, yielding a peak memory bandwidth of 29.9 GB/s. The AMD processor supports DDR4 memory, also dual-channel, with a peak bandwidth of 38.4 GB/s. That is a 28.4% bandwidth advantage for AMD, which matters for integrated graphics performance and memory-heavy applications. Neither processor supports ECC memory.

Other platform differences include the socket: Intel uses BGA 1168, while AMD uses Socket FP5. The PCIe implementation also differs: the Intel part provides Gen 2 with 12 lanes (CPU only), whereas the AMD part offers Gen 3 with 8 lanes (CPU only). The AMD part's PCIe Gen 3 support is newer and faster per lane, though the Intel part has more total lanes.

Integrated graphics present another contrast. The Intel Core i5-5250U ships with Intel HD 6000, while the AMD Ryzen 3 2300U includes Radeon Vega 6. The database does not record direct graphics benchmarks, so no quantitative comparison is possible, but the architectural differences in memory bandwidth and GPU configuration suggest the AMD part likely has an advantage in graphics-heavy tasks.

Production status and release timing also distinguish these parts. The Intel Core i5-5250U was released on 2015-02-28 and is now end-of-life. The AMD Ryzen 3 2300U was released on 2018-01-07 and remains active. The Intel part carries a launch MSRP of $315, while no launch MSRP is recorded for the AMD part. Neither processor has an unlocked multiplier.

Where Each One Wins

The benchmark data paints a clear picture of workload suitability for each processor. The AMD Ryzen 3 2300U wins in multi-threaded performance by a wide margin, making it the stronger choice for tasks that scale across cores. Video encoding, 3D rendering, batch photo processing, software compilation, and multitasking with many background threads are all workloads where the Ryzen 3 2300U's four physical cores provide a decisive advantage. The 50.5% lead in Cinebench R15 multi-core is the single largest win recorded in the database, and the 29% lead in Geekbench multi-core confirms that this advantage extends beyond a single benchmark.

The Intel Core i5-5250U wins the single-core race, as demonstrated by its 5.4% lead in Geekbench single-core. This advantage matters for applications that rely heavily on single-threaded performance: legacy software, certain database operations, spreadsheet calculations, and day-to-day responsive desktop use where the primary bottleneck is per-core speed rather than total throughput. The Intel part's higher single-core score suggests it may provide snappier feel in light, interactive workloads, even though its overall multi-core performance is far behind.

The average benchmark scores place the AMD part slightly ahead overall, with 880 versus 856, a 2.8% difference. This suggests that for a balanced mix of workloads, the Ryzen 3 2300U has a modest edge. However, the Intel part's single-core win and its lower average score gap indicate that users who prioritize single-threaded performance over everything else should not dismiss the i5-5250U.

The production status difference is also worth noting for practical selection. The Intel Core i5-5250U is end-of-life, meaning it is no longer in production and may be harder to source new. The AMD Ryzen 3 2300U is active, so it remains available in current systems. For anyone choosing between these two in a new purchase, the active status of the AMD part is a practical advantage.

The Verdict

The benchmark data is unambiguous: the AMD Ryzen 3 2300U is the stronger processor for the vast majority of use cases. Its 50.5% lead in Cinebench R15 multi-core and 29% lead in Geekbench multi-core are substantial margins that cannot be ignored. The four physical cores, higher clock speeds, more cache, and faster DDR4 memory support give it a comprehensive hardware advantage that shows up directly in the recorded scores. The fact that both processors share the same 15 W TDP makes the AMD part's dominance even more meaningful, as it delivers far more performance within the same power envelope.

The Intel Core i5-5250U does retain one clear victory: single-core performance. Its 5.4% lead in Geekbench single-core means that for tasks that cannot use more than one or two threads, the Intel part is measurably faster. This is not a marginal difference; it is a real, reproducible advantage. Users who run primarily single-threaded applications or who value low-latency responsiveness above all else may prefer the Intel part.

However, the overall picture favors AMD. The average benchmark score of 880 versus 856 puts the Ryzen 3 2300U ahead, and its multi-threaded wins are far larger than its single-threaded loss. The Intel part's sole head-to-head win is by 5.4%, while the AMD part's wins are by 50.5% and 29%. The magnitude of the losses matters more than the count of wins. For any user whose workload includes even a moderate amount of parallel processing, the AMD Ryzen 3 2300U is the clear choice.

The production status reinforces this conclusion. The Intel Core i5-5250U is end-of-life, while the AMD Ryzen 3 2300U is active. Choosing the AMD part means selecting a processor that is still in production and supported. Choosing the Intel part means accepting an older, discontinued component with a narrower performance profile. The data supports the AMD Ryzen 3 2300U for most buyers, with the Intel Core i5-5250U reserved for those who absolutely need single-threaded performance and can accept the multi-threaded deficit.
