AMD Ryzen 5 7500X3D vs AMD Ryzen AI 5 330 Comparison

AMD Ryzen 5 7500X3D and AMD Ryzen AI 5 330 represent two distinct design philosophies within AMD's current lineup. The 7500X3D is a desktop part built for maximum cache and raw throughput, while the Ryzen AI 5 330 is a mobile processor optimized for efficiency and integrated graphics. The benchmark data shows a decisive performance gap in most metrics, but the single-thread results and the physical platform differences tell a more nuanced story.

Head-to-Head Benchmarks

The recorded data shows the AMD Ryzen 5 7500X3D winning 9 of the 11 head-to-head benchmark comparisons, often by substantial margins. The largest single victory comes in the passmark_find_prime_numbers test, where the 7500X3D scores 221 against the Ryzen AI 5 330's 42, a delta of 426.2%. This test is heavily dependent on cache hierarchy, and the 7500X3D's 96 MB of shared L3 cache provides a massive advantage over the mobile chip's 4 MB.

The physics workload shows a similar pattern, with the 7500X3D scoring 2779 versus 705, a 294.2% advantage. This test typically scales with core count and memory bandwidth, and the desktop chip's 6 cores and 12 threads outperform the mobile chip's 4 cores and 8 threads. The multithread benchmark confirms this trend: 25047 for the 7500X3D against 12797 for the Ryzen AI 5 330, a 95.7% delta.

Data compression and encryption workloads also favor the desktop part heavily. The 7500X3D scores 271649 in passmark_data_compression versus 152012, a 78.7% lead. In passmark_data_encryption, the margin is even larger at 117.9%, with scores of 15797 and 7251 respectively. These results indicate that the 7500X3D's larger cache and higher base clock of 4.00 GHz provide a significant throughput advantage over the Ryzen AI 5 330's 2.00 GHz base clock.

Integer and floating-point math results follow the expected hierarchy. The 7500X3D scores 70774 in integer math versus 37771, an 87.4% delta, and 43594 in floating-point math versus 26196, a 66.4% delta. Extended instruction workloads show an 83.9% advantage for the desktop chip, scoring 20455 against 11124. Random string sorting, which tests memory latency and pointer-chasing performance, shows a 103.8% delta in favor of the 7500X3D, with scores of 32999 and 16188.

The only two benchmark wins for the AMD Ryzen AI 5 330 come in the single-thread tests. It scores 3515 in both passmark_single_thread and passmark_singlethread, edging out the 7500X3D's 3494 by a slim 0.6% margin. This is a notable result, as it indicates the mobile chip's Zen 5 architecture provides better single-core efficiency despite its lower power envelope. The boost clocks are identical at 4.50 GHz, so the difference comes down to architectural efficiency per clock.

The Verdict

The benchmark data presents a clear split based on use case. The AMD Ryzen 5 7500X3D is the dominant performer in every multithreaded and cache-sensitive workload, with an average benchmark score of 44573 compared to the Ryzen AI 5 330's 18811. The desktop chip sits in the 89th percentile of all CPUs, while the mobile part ranks in the 73rd percentile. For users running compression, encryption, physics simulations, or heavy math workloads, the 7500X3D delivers between 66% and 426% more performance.

The Ryzen AI 5 330's advantage is narrow but real: it wins single-thread performance by 0.6%. This means for lightly threaded applications that depend on a single core's efficiency, the mobile chip is marginally faster. However, this 21-point difference in passmark single-thread scores is small enough that most users would not notice it in daily use. The mobile chip's 28 W TDP against the desktop part's 65 W TDP makes it the clear choice for battery-powered systems, but the data shows no performance scenario where the Ryzen AI 5 330 outclasses the 7500X3D except for this single-thread edge.

The nearest rivals in the database reinforce this positioning. The 7500X3D's closest competitor is the Intel Core i5-14600 with an average score of 44889, putting it 0.7% ahead of the AMD part. The Ryzen AI 5 330's nearest rival is the AMD EPYC 7773X at 18979, which is 0.9% ahead. These deltas are small, suggesting both chips are well-positioned within their respective performance classes.

Where Each One Wins

The AMD Ryzen 5 7500X3D wins in all scenarios that benefit from large cache capacity and high thread counts. Its 96 MB shared L3 cache is critical for the 426.2% lead in prime number finding and the 294.2% lead in physics. Data compression, which relies on pattern matching and caching, shows a 78.7% advantage. For users working with archives, databases, or scientific computing, the 7500X3D's cache hierarchy delivers outsized gains.

The Ryzen AI 5 330 wins specifically in single-thread performance and power efficiency. Its 0.6% single-thread lead comes from the Zen 5 architecture, which is newer than the 7500X3D's Raphael design based on Zen 4. The 28 W TDP versus 65 W means the mobile chip can sustain performance in thermally constrained environments. The mobile chip also supports LPDDR5X memory, which the desktop part does not, and its 89.6 GB/s memory bandwidth is higher than the 7500X3D's 83.2 GB/s.

Multi-threaded workloads favor the 7500X3D by 95.7%, making it the better choice for rendering, video encoding, or any task that scales with core count. The mobile chip's 4 cores and 8 threads simply cannot match the desktop part's 6 cores and 12 threads in parallel workloads. However, the Ryzen AI 5 330's integrated Radeon 820M graphics are more capable for mobile use than the 7500X3D's Radeon Graphics, though the benchmark data does not include graphics tests.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 5 7500X3D is based on the Raphael codename with a Zen 4 architecture, built on a 5 nm process at TSMC. It uses 11,270 million transistors on a 71 mm² die. The AMD Ryzen AI 5 330 uses the Krackan Point 2 codename with a Zen 5 architecture, built on a 4 nm process at TSMC. The database does not list transistor count or die size for the mobile part.

Cache configurations differ dramatically. The 7500X3D has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 96 MB of shared L3 cache. The Ryzen AI 5 330 has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and only 4 MB of L3 cache. This 92 MB difference in shared cache is the primary reason for the desktop chip's dominance in cache-sensitive workloads.

The Ryzen AI 5 330 uses AMD Socket FP8 and supports PCIe Gen 4 with 14 lanes. Both support DDR5 memory in dual-channel mode, but the mobile chip also supports LPDDR5X. Memory bandwidth is higher on the mobile part at 89.6 GB/s versus 83.2 GB/s. ECC memory is supported on the desktop chip but not on the mobile chip.

The integrated graphics differ as well: the 7500X3D uses Radeon Graphics, while the Ryzen AI 5 330 uses Radeon 820M. The desktop part's launch MSRP is $269, while the mobile part has no listed MSRP. The release dates are also different, with the mobile chip arriving in July 2025 and the desktop chip in November 2025. Both processors have locked multipliers and are in active production.
