AMD Ryzen 5 PRO 2500U vs Intel Core i5-2300 Comparison

Head-to-Head Benchmarks

The database contains one overlapping benchmark between the AMD Ryzen 5 PRO 2500U and the Intel Core i5-2300: Cinebench R15 multi-core. The result is decisive. The AMD part scores 553 points, while the Intel part scores 296 points. That gives the Ryzen 5 PRO 2500U a 86.8% advantage, nearly double the output of the older desktop chip. This is a massive gap in a multi-threaded workload, reflecting not just architectural efficiency but also the thread count difference: the AMD processor has 8 threads versus 4 on the Intel.

Looking beyond the single shared test, the broader benchmark data reinforces the pattern. The AMD Ryzen 5 PRO 2500U records an average benchmark score of 1024 across its tested workloads. The Intel Core i5-2300 averages 1014. The difference is narrow, only about 1%, but it is notable given the contexts. The AMD part is a 15-watt mobile chip, while the Intel part is a 95-watt desktop chip from an older generation. The fact that the mobile chip edges ahead on average, despite the massive power disparity, speaks to how much architectural progress has been made.

In Cinebench R15 single-core, the AMD scores 134 points. The Intel part has no directly comparable single-core score in the shared head-to-head data, but its Cinebench R20 and R23 single-core results are 174 and 416 respectively. These are different test versions, so direct cross-test comparisons are not valid. However, the multi-core gap is so large that it dominates the narrative.

The Geekbench results for the AMD part show a multi-core score of 2540 and a single-core score of 867. Again, there is no direct Intel equivalent in the shared benchmark list, but the average scores across all tests provide context. The AMD chip sits in the 28th percentile of all CPUs in the database. The Intel chip also sits in the 28th percentile. Despite the wildly different release dates, power envelopes, and architectures, both processors land at the same percentile rank, meaning they are roughly equivalent in overall standing among all recorded CPUs.

The nearest rivals for the AMD Ryzen 5 PRO 2500U include the AMD Phenom II X6 1075T at an identical average score of 1024 (0% delta), the Intel Core i7-975 at 1023 (0.1% ahead), the Intel Processor N150 at 1025 (0.1% behind), and the Intel Pentium Gold G5600 at 1022 (0.2% ahead). This puts the Ryzen 5 PRO 2500U in a strange neighborhood: it is trading blows with a six-core Phenom from 2010 and a quad-core Nehalem from 2009, while also matching a modern low-power Intel N150. The performance class is consistent, but the power efficiency is not.

For the Intel Core i5-2300, the nearest rivals are the Intel Xeon W5580 at 1012 (0.2% behind), the Intel Core i7-2675QM at 1012 (0.2% behind), the Intel Core i3-4160 at 1017 (0.3% ahead), and the Intel Core i3-7100H at 1009 (0.5% ahead). The i5-2300 is therefore bracketed by a server Xeon, a mobile quad-core from the same era, and two much newer i3 parts. Its position in the database is consistent with a mid-range Sandy Bridge desktop chip, but its lack of multi-threading shows up clearly in the Cinebench R15 result.

The wins tally in the head-to-head data is 1 for the AMD Ryzen 5 PRO 2500U and 0 for the Intel Core i5-2300. There is no benchmark in the shared set where the Intel part wins. The single shared test is a clean sweep for AMD.

The Verdict

The data points to a clear conclusion: the AMD Ryzen 5 PRO 2500U is the stronger processor in the one workload where both have recorded results, and it does so while operating in a completely different power class. The 86.8% lead in Cinebench R15 multi-core is not a marginal edge; it is a generational gap. The AMD chip's 8 threads versus 4 threads, combined with a much more modern architecture, delivers a result that the older Intel part cannot approach.

Who should pick the AMD Ryzen 5 PRO 2500U? Anyone prioritizing multi-threaded performance in a mobile form factor. The data shows a 553-point Cinebench R15 multi-core score, an average benchmark score of 1024, and a 28th percentile rank. It is an active product, still in production, and it pairs with Radeon Vega 8 integrated graphics. For a laptop user who needs to run parallel workloads, the benchmark evidence is unambiguous.

Who should pick the Intel Core i5-2300? The data is less kind. It is an end-of-life desktop part with a 95-watt TDP, 4 threads, and a Cinebench R15 multi-core score of 296, which is less than 54% of the AMD's score. Its average benchmark score of 1014 is within 1% of the AMD part, so in mixed workloads the gap narrows. But the Intel chip offers no benchmark win in the shared data, and it consumes more than six times the power on paper. The only scenario where the Intel part makes sense from this data is if the user is constrained to the LGA 1155 socket and DDR3 memory and has no interest in multi-threaded performance.

The percentile ranks tell the final story. Both chips sit at the 28th percentile, meaning they are statistically equivalent in the overall CPU landscape. But the AMD part achieves that standing with a 15-watt TDP, a 14 nm process, and a 2019 release date. The Intel part achieves it with a 95-watt TDP, a 32 nm process, and a 2011 release date. The database records the Intel chip as end-of-life, while the AMD chip remains active. For a new purchase, the choice is obvious. For an upgrade from an old Sandy Bridge desktop, the data suggests that even a low-power mobile Ryzen from eight years later is a meaningful step forward in multi-threaded work.

Specification Differences

The two processors differ on nearly every specification except core count and ECC memory support. Both have 4 cores, and neither supports ECC memory.

The AMD Ryzen 5 PRO 2500U has 8 threads, a base clock of 2000.00 MHz, and a boost clock of 3.60 GHz. The Intel Core i5-2300 has 4 threads, a base clock of 2.80 GHz, and a boost clock of 3.10 GHz. The Intel part has a higher base clock, but the AMD part has a higher boost clock.

The TDP difference is stark: 15 watts for the AMD part versus 95 watts for the Intel part. The AMD chip uses the AMD Socket FP5, while the Intel chip uses the Intel Socket 1155. The AMD part is a mobile segment product, while the Intel part is a desktop segment product.

Memory support differs completely. The AMD Ryzen 5 PRO 2500U supports DDR4 with a dual-channel bus and a memory bandwidth of 38.4 GB/s. The Intel Core i5-2300 supports DDR3 with a dual-channel bus, and no memory bandwidth figure is recorded in the database.

PCIe support also differs. The AMD part has PCIe Gen 3 with 8 lanes (CPU only). The Intel part has PCIe Gen 3 with 16 lanes (CPU only). The AMD part integrates Radeon Vega 8 graphics, while the Intel part integrates Intel HD 2000 graphics.

The release dates are far apart. The AMD Ryzen 5 PRO 2500U was released on 2019-01-07. The Intel Core i5-2300 was released on 2011-01-08. The part numbers differ: YM250BC4T4MFB for AMD, SR00D for Intel.

Architecture Differences

The architectural gap between these two processors spans nearly a decade of design evolution. The AMD Ryzen 5 PRO 2500U uses the Zen architecture with the Raven Ridge codename, built on a 14 nm process at GlobalFoundries. The Intel Core i5-2300 uses the Sandy Bridge architecture with the same codename, built on a 32 nm process at Intel.

The process node difference is significant: 14 nm versus 32 nm. This explains much of the power efficiency gap. The AMD chip fits into a 15-watt TDP, while the Intel chip requires 95 watts.

The cache configurations differ substantially. The AMD Ryzen 5 PRO 2500U has 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel Core i5-2300 has 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. The Intel part has more L3 cache overall, but the AMD part has more L1 and L2 cache per core.

The die sizes are comparable: 246 mm² for the AMD part and 216 mm² for the Intel part. However, the Intel part has a recorded transistor count of 1,160 million, while the AMD part has no transistor count in the database. The AMD chip is larger despite being on a smaller process node, likely due to the integrated Radeon Vega 8 graphics.

The generations reflect the architectural divide. The AMD part is from the Ryzen 5 generation under Zen (Raven Ridge). The Intel part is from the Core i5 generation under Sandy Bridge. The AMD part is the newer design by eight years, and the benchmark data shows the benefits of that age in multi-threaded workloads.

The memory architecture also differs. The AMD part uses DDR4, which is newer and faster, with a recorded bandwidth of 38.4 GB/s. The Intel part uses DDR3, with no bandwidth recorded. This memory difference, combined with the process node advantage, contributes to the AMD part's superior multi-core performance despite the Intel part's higher base clock.

Neither processor has an unlocked multiplier, so both are locked for overclocking. Neither supports ECC memory. The AMD part has 8 PCIe Gen 3 lanes, while the Intel part has 16 PCIe Gen 3 lanes. For a desktop user needing more PCIe lanes for expansion cards, the Intel part has an advantage. For a mobile user needing efficiency and multi-threading, the AMD part is clearly superior.
