AMD Ryzen 9 9850HX vs Intel Core 3 305 Comparison

The AMD Ryzen 9 9850HX and Intel Core 3 305 occupy opposite ends of the mobile performance spectrum, and the recorded benchmark data reflects a complete sweep. The Ryzen 9 9850HX wins all 11 head-to-head comparisons, with margins ranging from a modest 12.2% in single-threaded work to a staggering 435.5% in integer math. The Core 3 305, however, is not without its own merits. It is a 15-watt part designed for efficiency and basic productivity, whereas the Ryzen 9 9850HX is a 55-watt high-performance processor. The data indicates that the choice between them is less about which is faster and more about which workload profile and power envelope suits the intended system.

Where Each One Wins

The AMD Ryzen 9 9850HX is the clear victor in every measured category. Its most dominant performance comes in multi-threaded and compute-intensive tasks. The PassMark integer math score of 172,943 versus 32,295 gives it a 435.5% advantage, indicating that heavily parallel integer workloads, such as code compilation and scientific computing, will see massive gains. Similarly, data compression shows a 351% lead (662,381 vs 146,857), making it the superior choice for archiving, database operations, and any workload that involves significant data throughput. The 12-core, 24-thread configuration allows it to manage concurrent tasks with ease, a capability reflected in the 235% lead in the PassMark multithread test (51,722 vs 15,439).

The Intel Core 3 305, with its 6 cores and 6 threads, does not win any of the recorded benchmarks. Its competitive positioning lies in its power efficiency. The 15-watt TDP is a fraction of the Ryzen 9's 55-watt TDP, making it suitable for fanless or passively cooled designs and ultra-portable laptops where battery life is prioritized over raw performance. Its single-thread score of 3,977 is within 12.2% of the Ryzen 9's 4,461, meaning that for basic everyday tasks like web browsing and document editing, the user experience may feel surprisingly similar despite the massive multi-core gulf. The Core 3 305's integrated Intel Xe3 Graphics also provides a functional iGPU solution, though the Ryzen's Radeon 610M is present as well.

Head-to-Head Benchmarks

The head-to-head data shows a complete victory for the AMD Ryzen 9 9850HX, but the scale of the wins varies significantly by workload type. The smallest margin is in single-threaded performance, where the Ryzen 9 9850HX scores 4,461 against the Core 3 305's 3,977, a 12.2% difference. This indicates that the Zen 5 architecture in the Ryzen chip has a strong single-core advantage, but the Intel part is not uncompetitive in this metric.

The most lopsided result is in integer math, where the AMD part's 172,943 score dwarfs the Intel part's 32,295, a 435.5% lead. This is a direct consequence of the core and thread count disparity. In floating-point math, the Ryzen 9 9850HX scores 115,062 versus 42,284, a 172.1% advantage, showing its strength in scientific and engineering applications. Data encryption shows a 191.7% lead for AMD (32,139 vs 11,019), while extended instructions (e.g., AVX workloads) show a 297.4% lead (53,817 vs 13,543). The physics test, often correlated with gaming performance, shows a 147.7% advantage for the AMD chip (3,054 vs 1,233). Random string sorting, a proxy for database and sorting algorithms, reveals a 298.2% lead for the Ryzen 9 9850HX (70,175 vs 17,623). Data compression shows a 351% lead for the AMD part. The Core 3 305's average benchmark score is 18,302, putting it in the 72nd percentile, while the Ryzen 9 9850HX's average score of 106,413 places it in the 97th percentile. The Ryzen's nearest rivals are high-end Xeon and EPYC server chips, with a 0.2% lead over the Intel Xeon w7-3555 and a 3% lead over the AMD EPYC 8324P, whereas the Core 3 305 trades within 0.4% of the Intel Core i3-14100 and the AMD Ryzen 5 2600E.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen 9 9850HX has 12 cores and 24 threads, while the Intel Core 3 305 has 6 cores and 6 threads, meaning the Intel part lacks Simultaneous Multi-Threading (SMT). The Ryzen 9's base clock is 3.00 GHz with a 5.20 GHz boost, compared to the Core 3 305's 1.50 GHz base and 4.30 GHz boost. The AMD part's TDP is 55 watts, while the Intel part is rated at 15 watts.

Memory support also diverges. The Ryzen 9 9850HX uses a dual-channel DDR5 interface with 89.6 GB/s of bandwidth and supports ECC memory. The Core 3 305 supports both DDR5 and LPDDR5X but operates on a single-channel bus with 59.7 GB/s of bandwidth and no ECC. PCIe connectivity differs as well: the AMD chip offers Gen 5 with 28 CPU lanes, while the Intel chip offers Gen 4 with only 6 CPU lanes. The Ryzen 9 9850HX uses an AMD Socket FL1, whereas the Core 3 305 uses Intel BGA 1516. The AMD processor has an unlocked multiplier, the Intel processor does not. The Intel Core 3 305 has a launch MSRP of $309.

Architecture Differences

The architectural divide is substantial. The AMD Ryzen 9 9850HX is built on the Zen 5 architecture with the codename Fire Range, part of the 9000 series. It is manufactured on a 4 nm process by TSMC, contains 16,630 million transistors, and uses a dual-die design with a total die size of 2x 70.6 mm². Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The Intel Core 3 305 uses the Wildcat Lake architecture, fabricated on a 3 nm process by Intel. It features a unified 192 KB L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD part's integrated graphics are the Radeon 610M, while the Intel part uses the Intel Xe3 Graphics with 1 Xe core. The Ryzen 9 9850HX was released on January 5, 2025, while the Core 3 305 was released on April 15, 2026. The AMD chip is part of the Ryzen 9 generation, and the Intel chip is part of the Core 3 generation. The raw architectural differences, such as the dual-die TSMC design versus Intel's monolithic 3 nm approach, explain the performance gulf, but the 40-watt TDP difference is the primary factor that separates these two mobile processors in the database's measurements.
