AMD Ryzen AI 5 430 vs Intel Core 3 305 Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen AI 5 430 and the Intel Core 3 305 is lopsided in raw count, but the three wins for the AMD part land in specific, meaningful workloads. The AMD Ryzen AI 5 430 takes the lead in Cinebench R15 single-core, PassMark data compression, and PassMark integer math. The Intel Core 3 305 wins the remaining twelve recorded comparisons, including every multi-core render test, all but one PassMark compute workload, and both single-thread PassMark results.

For users focused on integer-heavy processing, the AMD Ryzen AI 5 430 delivers a 22.7% advantage over the Intel chip in PassMark integer math, and its 8.2% edge in data compression suggests strength in archiving, database-style workloads, and similar integer-sorting tasks. The Cinebench R15 single-core win for AMD is dramatic at 44.6% ahead, though this does not carry over to the newer Cinebench R23 single-core test, where Intel leads by 3%. That inconsistency matters: the AMD part appears to excel in older single-threaded render tests but loses ground in the current version.

The Intel Core 3 305 dominates the multi-core and throughput categories. Its Cinebench R23 multi-core score of 13123 versus 8130 for AMD is a 38% gap. The Intel part also wins PassMark multithread by 13.7%, PassMark physics by 41.1%, and PassMark floating-point math by 35.7%. For encryption, extended instructions, prime-number finding, random string sorting, and single-thread PassMark, Intel holds the lead with margins ranging from 5.7% to 61.7%.

The overall percentiles are close: AMD sits at the 73rd percentile of all CPUs, Intel at the 72nd. The average benchmark scores differ by about 7%, with AMD at 19617 and Intel at 18302. The Intel part's nearest rivals include the Intel Core i3-14100 with a delta of -0.1%, the Intel Core 5 330 at -0.2%, and the Intel Core 7 360 at -0.4%, placing it in a tight cluster. The AMD part's nearest rivals are the AMD Ryzen 5 5500 at +0.1%, Intel Core i5-12500 at -0.3%, Intel Core i5-11600KF at -0.5%, and Intel Core i7-10700F at +0.6%.

The Verdict

The data indicates two clearly different usage profiles. The AMD Ryzen AI 5 430 is the pick for integer math and data compression workloads, where its 22.7% and 8.2% leads respectively give it a functional edge. Its Cinebench R15 single-core advantage of 44.6% also suggests strong legacy single-threaded performance, though the newer Cinebench R23 single-core result narrows to a 3% deficit.

The Intel Core 3 305 is the pick for multi-threaded rendering, physics simulation, floating-point math, encryption, and extended instruction workloads. Its Cinebench R23 multi-core margin of 38% is the largest single gap in the comparison. The Intel part also leads in PassMark multithread by 13.7%, in floating-point by 35.7%, in encryption by 31.1%, and in prime-number finding by 61.7%. For users whose workloads rely on parallel compute or modern render engines, the Intel chip is the stronger choice.

The average benchmark scores favor AMD slightly, 19617 versus 18302, but that aggregate hides the Intel part's dominance in the majority of individual tests. The two chips sit at nearly identical percentiles, 73rd and 72nd, which reflects their overall parity in the broader CPU landscape. The Intel part carries a launch MSRP of $309.
