AMD Ryzen AI 7 450 vs Intel Core 3 305 Comparison

The AMD Ryzen AI 7 450 and Intel Core 3 305 are both mobile processors aimed at thin-and-light laptops, but the benchmark data shows they serve different performance priorities. The AMD part is a clear multi-threaded powerhouse, winning 12 of the 15 recorded head-to-head tests, while the Intel chip secures 3 wins in specific single-thread and specialized workloads. The Ryzen AI 7 450 sits at the 87th percentile of all CPUs in the database, while the Core 3 305 lands at the 72nd percentile. This gap in percentile ranking aligns with the large average benchmark score difference: the AMD processor averages 39485, compared to 18302 for the Intel part. The data indicates that users prioritizing sustained multi-core work should look to the AMD chip, while the Intel processor holds its own in a few narrow tasks.

Where Each One Wins

The AMD Ryzen AI 7 450 dominates in nearly every multi-threaded and compute-heavy workload. Its biggest advantage appears in integer math, where it scores 88531 against Intel's 32295, a 174.1% lead. Data compression also favors AMD heavily, with a score of 315906 versus 146857, a 115.1% difference. The Cinebench R23 multi-core test shows a 39.6% advantage for AMD, with scores of 18316 and 13123 respectively. These results indicate that the Ryzen AI 7 450 is the stronger choice for rendering, compilation, and any workload that scales across many cores and threads.

The Intel Core 3 305 wins in two benchmark categories: prime number finding and single-thread performance. In the PassMark find prime numbers test, Intel scores 115 against AMD's 89, a 22.6% advantage for Intel. The single-thread tests are close, with Intel at 3977 and AMD at 3901, giving Intel a 1.9% edge. These results suggest that Intel's architecture has a slight efficiency advantage in certain scalar or latency-sensitive tasks, even though it trails significantly in parallel workloads.

Head-to-Head Benchmarks

The head-to-head data reveals a consistent pattern of AMD dominance in parallel workloads. In Cinebench R15 multi-core, the AMD Ryzen AI 7 450 scores 2713 while the Intel Core 3 305 scores 1322, giving AMD a 105.2% advantage. This is the largest multi-core gap in the Cinebench tests. The Cinebench R23 multi-core test shows a smaller but still substantial 39.6% lead for AMD. Across all Cinebench tests, AMD wins both multi-core and single-core variants, with single-core leads of 15.6% in R15 and 10% in R23.

The PassMark suite paints a similar picture. AMD leads in floating point math with a score of 54447 versus 42284, a 28.8% advantage. In data encryption, AMD scores 16247 against Intel's 11019, a 47.4% lead. Extended instructions favor AMD at 22400 versus 13543, a 65.4% gap. Random string sorting shows AMD at 35648 versus 17623, a 102.3% difference. The multithread test gives AMD a 70.7% lead with 26350 against 15439. Physics simulation also favors AMD, with a 28% advantage at 1578 versus 1233.

Intel's wins are limited to two tests. The find prime numbers test is the only clear Intel victory, with a 22.6% advantage. The single-thread tests are essentially a tie, with Intel ahead by just 1.9%. Notably, the Intel Core 3 305's single-thread score of 3977 is slightly higher than the AMD part's 3901, but the difference falls within a range that could be considered noise. Overall, the AMD processor holds a decisive lead in 12 of the 15 recorded benchmarks, with an average benchmark score more than double that of the Intel chip.

Specification Differences

The two processors differ significantly in core and thread counts. The AMD Ryzen AI 7 450 has 8 cores and 16 threads, while the Intel Core 3 305 has 6 cores and 6 threads. This 2-core and 10-thread difference explains much of the multi-core performance gap. Clock speeds also differ: the AMD chip has a base clock of 2.00 GHz and a boost clock of 5.10 GHz, while the Intel chip has a base clock of 1.50 GHz and a boost clock of 4.30 GHz. The AMD part's higher boost clock gives it an advantage in burst workloads.

Thermal design power differs as well, with the AMD processor rated at 28 W and the Intel processor at 15 W. The AMD part uses an AMD Socket FP8, while the Intel part uses Intel BGA 1516. Memory support shows a major split: the AMD chip supports dual-channel memory with a bandwidth of 89.6 GB/s, while the Intel chip is single-channel with a bandwidth of 59.7 GB/s. The AMD processor also supports ECC memory, while the Intel processor does not. PCIe lane counts differ, with AMD offering Gen 4 with 16 lanes and Intel offering Gen 4 with 6 lanes. Integrated graphics also differ: AMD uses the Radeon 860M, while Intel uses the Xe3 Graphics (1 Xe).

Architecture Differences

The AMD Ryzen AI 7 450 is built on the Zen 5 architecture with the codename Gorgon Point, part of the Ryzen AI 400 generation. It uses a 4 nm process from TSMC and has a die size of 195 mm². The cache layout is per-core: 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. This per-core L1 and L2 design scales with the 8-core count, providing a total of 640 KB of L1 and 8 MB of L2 across the chip.

The Intel Core 3 305 uses the Wildcat Lake codename and belongs to the Core 3 generation. It is fabricated on a 3 nm process by Intel, a smaller node than the AMD part's 4 nm. The cache structure is different: 192 KB of L1 total, 2.5 MB of L2 total, and 6 MB of shared L3. Intel's L3 is explicitly shared across all cores, while AMD's L3 is presented as a single 8 MB pool. The Intel chip's smaller total cache and lower thread count align with its lower multi-core performance. The AMD part's Zen 5 architecture with simultaneous multithreading gives it a substantial throughput edge in the recorded benchmarks, while Intel's architecture shows a slight advantage in the find prime numbers test and a marginal single-thread lead.
