AMD Ryzen 5 150 vs AMD Ryzen 7 9850X3D Comparison

The AMD Ryzen 5 150 and the AMD Ryzen 7 9850X3D occupy opposite ends of the processor spectrum. The Ryzen 5 150 is a 6-core, 12-thread mobile part built on the Zen 3+ architecture, designed for efficiency within a 35 W power envelope. The Ryzen 7 9850X3D is an 8-core, 16-thread desktop processor using the newer Zen 5 architecture, with a 120 W power envelope and a large shared L3 cache. In every recorded benchmark comparison, the Ryzen 7 9850X3D delivers a higher score, with the largest margins appearing in multi-threaded and physics workloads. The data shows a clear performance hierarchy, but the Ryzen 5 150 still holds relevance in its mobile segment due to its low power draw and integrated Radeon 660M graphics.

Where Each One Wins

The benchmark results show an unbroken sweep for the AMD Ryzen 7 9850X3D across all 11 head-to-head comparisons. The Ryzen 5 150 records zero wins in the matched tests, meaning there is no workload category in the database where it outpaces the desktop part. The Ryzen 7 9850X3D wins in data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithreaded performance, physics, random string sorting, and single-thread performance.

The Ryzen 5 150 does not win any benchmark, but its role is defined by its market segment. It is listed as a Mobile processor with a 35 W power envelope, compared to the 120 W desktop part. Its integrated Radeon 660M graphics provide a visual output solution, whereas the Ryzen 7 9850X3D includes a basic Radeon Graphics unit. The Ryzen 5 150 uses 35 W as its thermal design power, which is substantially lower than the 120 W of the Ryzen 7 9850X3D. That power difference defines its intended use case: lightweight mobile systems where battery life and cooling matter more than raw compute throughput.

The Ryzen 7 9850X3D, by contrast, targets desktop workloads where performance is the primary goal. It reaches the 84th percentile among all CPUs in the database, while the Ryzen 5 150 reaches the 84th percentile as well. The Ryzen 7 9850X3D reaches the 92nd percentile, placing it ahead of the majority of recorded processors. The Ryzen 5 150 sits at the 84th percentile, which is still a solid standing but clearly below the desktop part.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 5 150 uses Zen 3+ with the codename Rembrandt-R, fabricated on a 6 nm process at TSMC. The Ryzen 7 9850X3D uses Zen 5 with the codename Granite Ridge, fabricated on a 4 nm process at the same foundry. The process node difference of 6 nm versus 4 nm is a major factor in transistor density and power efficiency.

The core counts differ: 6 cores and 12 threads for the Ryzen 5 150, versus 8 cores and 16 threads for the Ryzen 7 9850X3D. The Ryzen 5 150 has a base clock of 3.30 GHz and a boost clock of 4.55 GHz. The Ryzen 7 9850X3D runs at a base clock of 4.70 GHz and a boost clock of 5.60 GHz. Those clock speeds are substantially higher on the desktop part, contributing to its dominance in both single-thread and multi-thread workloads.

Cache configurations are also different. The Ryzen 5 150 uses 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The Ryzen 7 9850X3D uses 80 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3. The L3 cache difference is large: 16 MB on the mobile part versus 96 MB on the desktop part. That 96 MB shared L3 is the defining feature of the X3D line, designed to reduce memory latency in cache-sensitive workloads.

The memory support is DDR5 for both parts, with dual-channel memory buses. The memory bandwidth differs, with 76.8 GB/s for the Ryzen 5 150 and 89.6 GB/s for the Ryzen 7 9850X3D. ECC memory support is present on the Ryzen 7 9850X3D, while the Ryzen 5 150 does not support ECC.

PCIe connectivity differs as well. The Ryzen 5 150 provides PCIe Gen 4 with 20 lanes from the CPU. The Ryzen 7 9850X3D provides PCIe Gen 5 with 24 lanes from the CPU. The newer standard and higher lane count give the desktop part more bandwidth for expansion cards and storage devices.

The Ryzen 7 9850X3D has an unlocked multiplier, while the Ryzen 5 150 does not. The desktop part also carries a higher transistor count of 8,315 million on a die size of 70.6 square millimeters. The Ryzen 5 150 has a die size of 210 square millimeters. The release dates differ, with the Ryzen 5 150 released on September 30, 2025, and the Ryzen 7 9850X3D released on January 28, 2026. The Ryzen 7 9850X3D has a launch MSRP of $499.

Head-to-Head Benchmarks

The largest performance gap in the head-to-head results appears in the prime number search test. The Ryzen 5 150 scores 47, while the Ryzen 7 9850X3D scores 435, a difference of 89.2 percent in favor of the desktop part. This test is highly sensitive to integer execution and cache behavior, both of which favor the Zen 5 architecture and the larger L3 cache.

The physics test shows the second-largest margin. The Ryzen 5 150 scores 806, while the Ryzen 7 9850X3D scores 4,171, an 80.7 percent advantage. Physics simulations often rely on multi-threaded scaling, and the 8-core, 16-thread configuration of the Ryzen 7 9850X3D provides a clear edge over the 6-core, 12-thread Ryzen 5 150.

The extended instructions test shows a 62.6 percent gap. The Ryzen 5 150 scores 14,675, while the Ryzen 7 9850X3D scores 39,272. This test measures SIMD and advanced instruction throughput, where the newer Zen 5 core design and higher clocks contribute to the result.

The multithreaded PassMark score shows a 57.7 percent gap. The Ryzen 5 150 scores 17,492, while the Ryzen 7 9850X3D scores 41,318. This is a broad measure of overall multi-threaded capability, and the desktop part leads by a wide margin.
