AMD Ryzen AI 7 345 vs Intel Core 3 305 Comparison

The database compares two mobile processors from different design directions: the AMD Ryzen AI 7 345, a Krackan Point part with 6 cores and 12 threads, and the Intel Core 3 305, a Wildcat Lake part with 6 cores and 6 threads. Across all recorded benchmarks, the AMD chip averages 29461 and ranks at the 81st percentile of all CPUs, while the Intel chip averages 18302 and ranks at the 72nd percentile. In direct head-to-head tests, AMD takes 9 wins and Intel takes 6.

Head-to-Head Benchmarks

The largest head-to-head margin belongs to AMD in PassMark integer math: 63475 to 32295, a 96.5% advantage. The same pattern appears in data compression, where AMD scores 237484 against Intel's 146857, a 61.7% lead. AMD also wins Cinebench R15 single-core by a wide margin, 271 to 186 (45.7%), and random string sorting by 44.3% (25435 vs 17623). The multithreaded PassMark result goes to AMD by 29.1% (19927 vs 15439), while Cinebench R15 multi-core goes to AMD by 29.5% (1712 vs 1322). Extended instructions favor AMD by 25.5% (17003 vs 13543), data encryption by 7.2% (11814 vs 11019), and floating-point math by a narrow 0.8% (42621 vs 42284).

Intel's biggest win is PassMark find prime numbers, where it scores 115 versus AMD's 62, a 46.1% margin. Intel also wins Cinebench R23 multi-core, 13123 to 11461 (12.7% ahead), and PassMark physics, 1233 to 1089 (11.7% ahead). In the single-thread tests, Intel takes PassMark single-thread 3977 to 3875 (2.6% ahead) and Cinebench R23 single-core 1852 to 1818 (1.8% ahead).

The split is striking: AMD wins both Cinebench R15 tests and most PassMark throughput tests, while Intel wins both Cinebench R23 tests and the prime-number and physics pair. The head-to-head tally is 9 wins for AMD and 6 for Intel.

Architecture Differences

The two processors use different nodes and foundries. AMD builds the Ryzen AI 7 345 on TSMC's 4 nm process, while Intel builds the Core 3 305 on its own 3 nm process. AMD's codename is Krackan Point with the Ryzen AI 300 (Zen 5 / Zen 5c) generation; Intel's codename is Wildcat Lake with the Core 3 (Wildcat Lake) generation.

Core counts match at 6, but thread counts do not: AMD has 12 threads, Intel has 6. AMD's base clock is 2.00 and boost clock is 4.60; Intel's base clock is 1.50 and boost clock is 4.30. The TDP figures are 28 for AMD and 15 for Intel. AMD uses AMD Socket FP8, Intel uses Intel BGA 1516.

The cache layouts differ. AMD lists L1 as 80 KB per core, L2 as 1 MB per core, and L3 as 4 MB. Intel lists L1 as 192 KB, L2 as 2.5 MB, and L3 as 6 MB shared. Both support DDR5 and LPDDR5X, but AMD uses a dual-channel memory bus with 89.6 GB/s bandwidth, while Intel uses a single-channel bus with 59.7 GB/s. PCIe connectivity also differs: AMD provides Gen 4 with 14 lanes (CPU only), Intel provides Gen 4 with 6 lanes (CPU only).

Integrated graphics differ as well: AMD uses the Radeon 840M, Intel uses Intel Xe3 Graphics (1 Xe). The release dates are 2025-01-14 for AMD and 2026-04-15 for Intel.

Where Each One Wins

AMD's wins concentrate in workloads that stress integer throughput, data movement, and multithreading. The PassMark integer math score of 63475 is nearly double Intel's 32295, and the data compression score of 237484 is far above Intel's 146857. Data encryption, extended instructions, random string sorting, and the PassMark multithread test all follow the same direction. The dual-channel memory bus and 12 threads give AMD a structural advantage in these tests.

Intel's wins are more specialized. The prime-number score of 115 versus 62 suggests a specific workload edge. The physics score of 1233 versus 1089 shows another Intel advantage. Cinebench R23 multi-core goes to Intel despite Intel having half the threads and a single-channel memory bus; the 13123 score beats AMD's 11461 by 12.7%. The two single-thread results are close: Intel leads PassMark single-thread by 2.6% and Cinebench R23 single-core by 1.8%, while AMD leads Cinebench R15 single-core by 45.7%.

The floating-point math test is effectively a tie: AMD 42621, Intel 42284, a 0.8% gap. The data therefore shows a workload-dependent split rather than a universal winner.

The Verdict

Looking at the overall averages, the AMD Ryzen AI 7 345 is the stronger processor in the database. Its average benchmark score is 29461, versus 18302 for the Intel Core 3 305, and its percentile rank is 81 versus 72. The nearest-rival data reinforces that separation: AMD's closest listed neighbor is the AMD Ryzen 7 3800X at 29447, with a 0% gap. AMD is 0.2% ahead of the AMD EPYC 9654 (29409), 0.7% ahead of the Intel Core i5-13500HX (29270), and 0.7% behind the AMD Ryzen 7 PRO 5755GE (29656). On the Intel side, the closest listed neighbor is the Intel Core i3-14100 at 18318, which the Core 3 305 trails by 0.1%. The Intel Core 5 330 (18345) is 0.2% higher, the Intel Core 7 360 (18374) is 0.4% higher, and the AMD Ryzen 5 2600E (18230) is 0.4% lower.

The data supports choosing the AMD part for workloads that resemble its wins: integer math, data compression, encryption, random string sorting, and multithreaded PassMark tasks. The data supports choosing the Intel part for workloads that resemble its wins: prime-number finding, physics, Cinebench R23 multi-core, and the PassMark single-thread test. The AMD part also offers more threads, a dual-channel memory bus, and higher memory bandwidth; the Intel part offers a lower TDP of 15 and a 3 nm process.
