AMD Ryzen 5 2500X vs Intel Core i3-10305 Comparison

Where Each One Wins

The recorded benchmark data presents an unusually clear-cut picture: the AMD Ryzen 5 2500X wins all six head-to-head comparisons against the Intel Core i3-10305. There is no single workload category where the Intel part takes the lead. The wins span both multi-threaded and single-threaded Cinebench tests, across three different versions of the renderer (R15, R20, and R23). This means the AMD chip holds an advantage in every measured scenario, from heavily threaded rendering workloads to lightly threaded tasks that rely on a single core.

The margin is consistent but narrow. In multi-core tests, the AMD Ryzen 5 2500X leads by 2.8% in Cinebench R15, 2.7% in R20, and 2.7% in R23. In single-core tests, the advantage is slightly smaller: 2.7% in R15, 2.6% in R20, and 2.6% in R23. The pattern suggests a uniform performance edge across the board rather than a workload-specific strength. The largest delta is 2.8% in the R15 multi-core test, and the smallest is 2.6% in both R20 and R23 single-core runs. The AMD part also posts a higher Cinebench R23 single-core score of 1134 versus 1105 for the Intel chip, and a multi-core score of 8036 versus 7828.

Looking at the broader database rankings, the AMD Ryzen 5 2500X sits at the 48th percentile among all CPUs, while the Intel Core i3-10305 sits at the 47th percentile. That one-point percentile gap aligns with the narrow benchmark margins. The average benchmark score for the AMD part is 2361, compared to 2264 for the Intel part, a difference of roughly 4.3%. The nearest rivals for the AMD chip include the Intel Xeon E-2226GE (average score 2365, delta of -0.2%), the Intel Core i5-9600 (2354, +0.3%), and the Intel Xeon E3-1285 v6 (2348, +0.6%). The nearest rivals for the Intel chip are the Intel Core i7-1068NG7 (2259, +0.2%), the Intel Core i5-9400 (2254, +0.4%), and the Intel Core i7-10710U (2248, +0.7%). These rival comparisons show that both parts are tightly clustered with their immediate peers, but the AMD part has a slightly higher absolute position.

The Verdict

The data dictates a straightforward choice: the AMD Ryzen 5 2500X is the superior processor in every benchmark recorded. If the selection is based purely on measured Cinebench performance, the AMD part wins all six head-to-head tests, with deltas ranging from 2.6% to 2.8%. There is no countervailing benchmark result in the database that would support choosing the Intel Core i3-10305 on performance grounds.

That said, the differences are modest. A 2.6% to 2.8% margin is unlikely to be perceptible in everyday use, and both processors occupy nearly identical percentile positions in the global CPU rankings (48th versus 47th). The AMD part's average benchmark score of 2361 is 97 points higher than the Intel part's 2264, which is a small but consistent gap. For a user prioritizing raw multi-core rendering performance, the AMD Ryzen 5 2500X is the clear pick based on the Cinebench R23 multi-core result of 8036 versus 7828. For a user prioritizing single-core responsiveness, the AMD part also wins, with a 1134 score versus 1105 in Cinebench R23 single-core.

The Intel Core i3-10305 does bring one differentiating feature that the AMD part lacks: integrated graphics. The Intel chip includes UHD Graphics 630, while the AMD Ryzen 5 2500X has no integrated graphics in the database. That means a system built around the AMD chip requires a discrete GPU, whereas the Intel part can output video without an add-in card. This is a hardware feature difference, not a performance metric, but it could influence platform selection for builds where a discrete GPU is not already planned. The data does not include any integrated graphics benchmarks, so the relative quality of Intel's iGPU cannot be assessed here.

In summary, the benchmark verdict is unanimous: the AMD Ryzen 5 2500X wins all six head-to-head tests and holds a higher average score, higher percentile ranking, and higher Cinebench results across the board. The Intel Core i3-10305 is the pick only if its integrated graphics are a required feature, since no performance metric in the database favors it.

Head-to-Head Benchmarks

The head-to-head results are fully one-sided, so the analysis focuses on the size and consistency of the AMD wins rather than which tests favor which side. The largest margin is in Cinebench R15 multi-core, where the AMD Ryzen 5 2500X scores 810 against the Intel Core i3-10305's 788, a delta of 2.8%. The single-core R15 test shows a nearly identical gap: 114 versus 111, a delta of 2.7%. Moving to Cinebench R20, the AMD part scores 3375 in multi-core versus 3287 for Intel, a delta of 2.7%. The R20 single-core result is 476 versus 464, a delta of 2.6%.

In the most recent Cinebench R23 tests, the AMD Ryzen 5 2500X posts a multi-core score of 8036, which is 208 points higher than the Intel Core i3-10305's 7828, a delta of 2.7%. The single-core R23 score is 1134 versus 1105, a delta of 2.6%. The consistency is notable: the delta stays within a narrow band of 2.6% to 2.8% regardless of the Cinebench version or the thread count. There is no sign of the gap widening or shrinking with workload intensity.

One way to interpret these numbers is through the nearest-rival context. The AMD part's average benchmark score of 2361 places it just 0.2% below the Intel Xeon E-2226GE (2365) and 0.3% above the Intel Core i5-9600 (2354). The Intel Core i3-10305's average of 2264 places it 0.2% above the Intel Core i7-1068NG7 (2259) and 0.4% above the Intel Core i5-9400 (2254). The two CPUs are each competitive within their own peer groups, but the AMD part's peer group sits at a higher absolute score level. The delta between the two parts' average scores (97 points) is roughly four times the delta between the AMD part and its closest rival (-0.2%), which highlights that the gap between the 2500X and the i3-10305 is larger than the typical spacing between adjacent CPUs in the database.

Architecture Differences

The two processors come from different manufacturers, sockets, and process nodes, though they share several core-level specifications. Both have 4 cores and 8 threads, both have a 65 W TDP, and both support dual-channel DDR4 memory with 8 MB of shared L3 cache. The similarities end there.

The AMD Ryzen 5 2500X is built on the Zen architecture (specifically Zen+ Pinnacle Ridge) using a 12 nm process at GlobalFoundries. Its die size is 213 mm², and it contains 4,800 million transistors. It uses the AMD Socket AM4 and has an unlocked multiplier, meaning the user can adjust the clock multiplier for overclocking. Its base clock is 3.60 GHz, and its boost clock is 4.00 GHz. The L1 cache is 96 KB per core, and the L2 cache is 512 KB per core. Memory bandwidth is rated at 46.9 GB/s. The part number is YD250XBBM4KAFYD250XBBAFMPK. It was released on 2018-09-09 and is currently marked as Active in production.

The Intel Core i3-10305 is built on the Comet Lake architecture (Comet Lake-R) using a 14 nm process at Intel. No transistor count or die size is recorded in the database. It uses the Intel Socket 1200 and has a locked multiplier, so the user cannot adjust the clock multiplier. Its base clock is 3.80 GHz, and its boost clock is 4.50 GHz, both higher than the AMD part. The L1 cache is 64 KB per core, and the L2 cache is 256 KB per core, both smaller than the AMD part. Memory bandwidth is rated at 42.7 GB/s, which is lower than the AMD part's 46.9 GB/s. It includes integrated UHD Graphics 630, which the AMD part lacks. The part number is SRH3K. It was released on 2021-03-15 and is also marked as Active.

The clock speed situation is worth noting: the Intel part has a higher base clock (3.80 GHz versus 3.60 GHz) and a higher boost clock (4.50 GHz versus 4.00 GHz), yet it still loses every benchmark. This points to architectural efficiency differences between Zen+ and Comet Lake, although the database does not provide per-clock performance metrics. The AMD part's larger L1 and L2 caches per core, combined with a higher memory bandwidth rating, may contribute to its benchmark advantage despite the lower clocks. The process node difference (12 nm for AMD versus 14 nm for Intel) is also recorded, though the database does not link process node directly to performance.

Both CPUs support PCIe Gen 3 with 16 lanes from the CPU, and neither supports ECC memory. The market segment for both is Desktop. The AMD part's generation is listed as "Ryzen 5 (Zen+ Pinnacle Ridge)", while the Intel part's generation is "Core i3 (Comet Lake)". The Intel part's release date is over two years later than the AMD part, but that does not translate into a benchmark advantage in the recorded data. The architecture differences are substantial on paper, but the measured outcomes show the AMD part ahead in every test by a consistent margin.
