AMD Ryzen 5 7500X3D vs AMD Ryzen AI 7 445 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen 5 7500X3D, which wins 9 of the 11 shared benchmark comparisons against the AMD Ryzen AI 7 445. The desktop part dominates in every multi-threaded and compute-heavy workload, while the mobile chip claims only the two single-thread entries by a narrow margin.

The largest gap appears in passmark_find_prime_numbers, where the Ryzen 5 7500X3D scores 221 against 56 for the Ryzen AI 7 445, a delta of 294.6%. This is an extreme outlier, but it reflects a fundamental difference in how the two processors handle integer-heavy, latency-sensitive algorithms. The physics test tells a similar story: the desktop chip scores 2779 versus 976, a 184.7% advantage. Both results indicate that the 7500X3D's large cache and higher base clock deliver outsized gains in workloads that depend on repeated memory access and branch prediction.

In passmark_multithread, the Ryzen 5 7500X3D posts 25047 against 18115, a 38.3% lead. This is the most representative overall throughput metric, and the margin is substantial. The desktop part also leads in passmark_random_string_sorting by 40.5% (32999 vs 23488), passmark_data_encryption by 50.2% (15797 vs 10519), and passmark_extended_instructions by 29.2% (20455 vs 15826). These are not small differences; they indicate that the 7500X3D is consistently faster across a broad range of computational patterns.

The Ryzen AI 7 445's only wins come in the two identical single-thread metrics: passmark_single_thread and passmark_singlethread, both scoring 3591 against 3494 for the 7500X3D, a delta of 2.7% in favor of the mobile chip. That is a modest but real advantage. The boost clock of 4.60 GHz on the Ryzen AI 7 445, compared to 4.50 GHz on the 7500X3D, partially explains this result, though the newer Zen 5 architecture likely contributes as well.

Intermediate results show the 7500X3D ahead in passmark_integer_math by 21.3% (70774 vs 58332), passmark_data_compression by 25.9% (271649 vs 215812), and passmark_floating_point_math by 10.8% (43594 vs 39362). Even the smallest of these margins, the floating-point gap, is meaningful enough to separate the two in scientific and analytical workloads.

The average benchmark scores reinforce the hierarchy. The 7500X3D records an average score of 44573, while the Ryzen AI 7 445 averages 26936. That is a 65.5% difference in overall performance, placing the desktop chip in the 89th percentile of all CPUs, versus the 79th percentile for the mobile part. In the nearest rivals table, the 7500X3D sits within 0.7% of the Intel Core i5-14600, while the Ryzen AI 7 445 is within 0.6% of the Intel Core i9-9900K, a much older desktop processor.

Where Each One Wins

The Ryzen 5 7500X3D wins in every category that benefits from sustained throughput and large data sets. Data compression, encryption, extended instruction workloads, prime number calculation, floating-point math, integer math, multithreaded rendering, physics simulation, and random string sorting all favor the desktop part. The 96 MB of shared L3 cache is the obvious differentiator here; it allows the 7500X3D to keep far more working data on-chip, reducing the need to access main memory. The higher 4.00 GHz base clock also helps in long-running parallel tasks, since the chip does not need to ramp up from a low idle frequency.

The Ryzen AI 7 445 wins only in single-thread performance, and only by 2.7%. This is a narrow but genuine edge for applications that are serial in nature and cannot utilize multiple cores. The 4.60 GHz boost clock and the Zen 5 architecture give it a slight per-core advantage. However, the practical impact is limited: a 2.7% gain in single-thread speed is unlikely to be perceptible in most real-world use, and it is dwarfed by the 7500X3D's multi-thread dominance.

For workloads that are fully parallel, the 7500X3D is the clear choice. The multithread score of 25047 versus 18115 means the desktop chip finishes roughly 38% more work in the same time. For workloads that are purely single-threaded, the Ryzen AI 7 445 is marginally faster, but the difference is small enough that most users would not notice. The physics result is particularly striking: 2779 versus 976, a 184.7% gap, which indicates that the 7500X3D is far better suited to simulation and physics-based computation.

The Verdict

The data points to a clear conclusion: the AMD Ryzen 5 7500X3D is the faster processor in nearly every measurable way. Its 9-to-2 win record in the head-to-head benchmarks, combined with a 65.5% higher average score, makes it the superior choice for any workload that uses multiple threads or large data sets. The 7500X3D also has a higher percentile ranking, 89 versus 79, and its nearest rivals include the Intel Core i5-14600, a modern desktop part, whereas the Ryzen AI 7 445's nearest rivals include the Intel Core i9-9900K, a 2018-era desktop chip.

The Ryzen AI 7 445 should only be chosen in scenarios where the single-thread advantage matters more than everything else. Its 2.7% lead in single-thread score is real, but it comes with a 38.3% deficit in multithread performance and a 50.2% deficit in encryption throughput. The mobile chip is also built for a different market segment: it uses a 28 W TDP and an FP8 socket, while the 7500X3D uses a 65 W TDP and an AM5 socket. The desktop part is designed for sustained performance in a tower chassis, while the mobile part is designed for battery-powered laptops. Within their respective design goals, the 7500X3D is the stronger performer, and the Ryzen AI 7 445 only justifies itself in power-constrained environments where its 28 W package is a requirement.

Architecture Differences

The two processors come from different AMD generations and use different manufacturing processes. The Ryzen 5 7500X3D is part of the 7000 series, based on the Zen 4 architecture with the codename Raphael. It is built on a 5 nm process at TSMC and contains 11,270 million transistors on a 71 mm² die. The Ryzen AI 7 445 is part of the Ryzen AI 400 series, using the Zen 5 architecture with the codename Gorgon Point. It is built on a 4 nm process at TSMC, though its transistor count and die size are not listed in the database.

The cache hierarchy differs substantially. The 7500X3D has 64 KB of L1 per core and 1 MB of L2 per core, with a massive 96 MB of shared L3 cache. The Ryzen AI 7 445 has 80 KB of L1 per core and 1 MB of L2 per core, but only 4 MB of L3 cache. The larger L1 on the mobile chip reflects the newer Zen 5 design, but the 96 MB versus 4 MB L3 difference is the most consequential architectural gap. It explains why the 7500X3D excels in data-heavy workloads: it can hold vastly more data on-chip.

The integrated graphics also differ. The 7500X3D uses Radeon Graphics, while the Ryzen AI 7 445 uses the Radeon 840M. The mobile part's graphics solution is likely more capable in a laptop context, but the database does not provide direct GPU benchmarks for comparison. Both processors support ECC memory.

Specification Differences

The socket and market segment separate the two clearly. The Ryzen 5 7500X3D uses AMD Socket AM5 and is classified as a Desktop processor, while the Ryzen AI 7 445 uses AMD Socket FP8 and is classified as Mobile. The desktop chip has a base clock of 4.00 GHz and a boost clock of 4.50 GHz, while the mobile chip has a base clock of 2.00 GHz and a boost clock of 4.60 GHz. The higher base clock on the 7500X3D is a major factor in its multi-thread performance, while the slightly higher boost clock on the Ryzen AI 7 445 contributes to its single-thread edge.

The TDP values are 65 W for the 7500X3D and 28 W for the Ryzen AI 7 445. Memory support differs: the desktop chip supports DDR5 only, while the mobile chip supports both DDR5 and LPDDR5X. Both use dual-channel memory buses, but the memory bandwidth is 83.2 GB/s for the 7500X3D and 89.6 GB/s for the Ryzen AI 7 445, giving the mobile part a slight advantage in theoretical memory bandwidth. The PCIe support also differs: the 7500X3D has Gen 5 with 24 lanes (CPU only), while the Ryzen AI 7 445 has Gen 4 with 14 lanes (CPU only). The release dates are 2025-11-11 for the 7500X3D and 2026-01-04 for the Ryzen AI 7 445. The 7500X3D has a launch MSRP of $269, while the Ryzen AI 7 445 has no listed launch MSRP. Neither processor has an unlocked multiplier.
