AMD Ryzen 9 9850HX vs Intel Core 7 251TE Comparison

Where Each One Wins

The recorded benchmark data presents an unusually one-sided comparison. Across all 11 head-to-head PassMark tests, the AMD Ryzen 9 9850HX takes every win, with zero victories for the Intel Core 7 251TE. This does not mean the Intel part is without merit, but its strengths lie in a different performance envelope than the AMD processor.

The AMD Ryzen 9 9850HX shows its largest advantages in workloads that stress instruction-level parallelism and extended operations. The extended instructions test delivers a 217.1% lead, the single largest delta in the entire dataset. This indicates the Zen 5 architecture handles SIMD-style workloads with substantially greater efficiency. Prime number finding follows at 130.7% ahead, reinforcing the per-core computational advantage.

Data compression shows a 98.1% delta in favor of AMD, a near doubling of throughput. Multithreaded performance lands 72.3% ahead, which is notable given the Intel part actually has more physical cores (24 versus 12). The AMD processor also leads in random string sorting by 77%, integer math by 37.5%, floating-point math by 34.4%, single-thread performance by 25%, encryption by 44.9%, and physics by 57.6%.

The Intel Core 7 251TE, despite losing every head-to-head PassMark test, still occupies the 88th percentile among all CPUs in the database. Its average benchmark score of 41,650 places it alongside Intel Core Ultra 7 265H (0.1% higher), Core i7-14650HX (0.2% higher), Core i7-12850HX (0.3% lower), and Core i7-14700T (0.6% lower). This is a capable desktop processor, but it is simply outclassed in this specific matchup.

The AMD processor sits in the 97th percentile overall, with an average score of 106,413. Its nearest rivals are all server-class Intel Xeon parts: the Xeon w7-3555 (0.2% higher), Xeon 6521P (0.5% higher), and Xeon w7-2595X (2.1% lower), plus the AMD EPYC 8324P (3% lower). This positioning reveals that the Ryzen 9 9850HX performs closer to workstation and server silicon than to mainstream desktop or mobile chips.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 9850HX uses the Zen 5 architecture with the Fire Range codename, built on a 4 nm TSMC process with 16,630 million transistors across a dual-die layout of 2x 70.6 mm². It is a mobile-market part with a 55W TDP, yet it delivers 12 cores and 24 threads. The base clock is 3.00 GHz with a boost clock of 5.20 GHz. The multiplier is unlocked, allowing overclocking headroom.

The Intel Core 7 251TE uses Bartlett Lake architecture on an Intel 10 nm process with a 215 mm² die size. It targets the desktop segment with a 45W TDP, which is lower than the AMD part despite having more cores. It offers 24 cores and 32 threads, but the base clock is just 1.40 GHz, rising to 5.40 GHz at boost. The multiplier is locked. The process node difference is significant: 4 nm versus 10 nm, which contributes to the AMD part's transistor density advantage despite the smaller core count.

Cache configurations also diverge. Both processors use 80 KB of L1 cache per core, but the L2 cache differs: AMD uses 1 MB per core, while Intel uses 1.25 MB per core. The L3 cache heavily favors AMD with 64 MB total versus Intel's 36 MB shared. This larger L3 pool likely explains some of the AMD advantage in compression and sorting workloads, which benefit from larger working sets residing on-chip.

Memory support shows a split. The AMD processor supports DDR5 only, with dual-channel bandwidth of 89.6 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel at 89.6 GB/s. Both support ECC memory. PCIe lanes favor AMD with Gen 5 and 28 CPU-only lanes, while Intel offers Gen 5 with 16 CPU-only lanes.

Integrated graphics differ: AMD pairs the CPU with Radeon 610M, while Intel uses UHD Graphics 770. The Intel part has a launch MSRP of $384; the AMD part has no recorded launch MSRP. Release dates are close, with AMD at January 5, 2025 and Intel at January 12, 2025. The AMD processor uses AMD Socket FL1, while Intel uses Socket 1700.

The Verdict

The data points to a clear conclusion for compute-heavy workloads: the AMD Ryzen 9 9850HX outperforms the Intel Core 7 251TE across every measured PassMark metric. The average benchmark score of 106,413 versus 41,650 represents a 155.5% gap. The AMD part also sits 9 percentile points higher in the global CPU ranking (97th versus 88th).

The Intel Core 7 251TE does offer advantages outside the PassMark suite. It has double the physical cores (24 versus 12) and more threads (32 versus 24). It supports both DDR4 and DDR5 memory, which provides flexibility for system builders with existing DDR4 platforms. Its lower TDP of 45W versus 55W indicates potentially lower power draw under sustained load, though the database does not include direct power measurements. The locked multiplier simplifies system design for OEM deployments where overclocking is not desired.

For users prioritizing raw computational throughput, single-thread responsiveness, or extended instruction performance, the AMD processor is the clear choice based on recorded data. For those needing maximum core counts for parallel workloads that scale beyond 12 threads, or requiring DDR4 compatibility, the Intel part remains viable. However, the benchmark results show that even with fewer cores, the AMD processor wins the multithreaded test by 72.3%, which suggests its per-core efficiency more than compensates for the core count disadvantage in these specific workloads.

The Intel part's nearest rivals include other Intel Core processors, indicating it sits in a mainstream performance tier. The AMD part's nearest rivals are Xeon workstation chips, placing it in a higher performance class entirely.

Head-to-Head Benchmarks

The extended instructions benchmark delivers the most dramatic separation. AMD scores 53,817 against Intel's 16,974, a 217.1% lead. This test typically measures workloads with heavy use of SSE or AVX instructions, where Zen 5's implementation shows clear superiority. The delta is so large that it alone accounts for a significant portion of the average score gap.

Data compression shows the second-largest gap at 98.1%. The AMD score of 662,381 versus 334,399 indicates the larger L3 cache (64 MB versus 36 MB) provides a meaningful advantage when compressing datasets that fit within the cache hierarchy. The AMD part nearly doubles the Intel throughput in this test.

Random string sorting follows at 77% ahead. AMD posts 70,175 against Intel's 39,643. This workload is sensitive to memory latency and cache hit rates, and the AMD design with its larger L3 and 4 nm process delivers better results. Multithreaded performance sits 72.3% ahead with scores of 51,722 versus 30,022. The AMD part achieves this despite having half the physical cores, demonstrating that core count alone does not determine multithreaded throughput in these measurements.

Physics simulation shows a 57.6% lead (3,054 versus 1,938). This test often relies on floating-point throughput and cache efficiency, both of which favor the AMD architecture. Data encryption runs 44.9% ahead (32,139 versus 22,176), indicating faster cryptographic operations. Integer math delivers 37.5% higher scores (172,943 versus 125,739), while floating-point math runs 34.4% ahead (115,062 versus 85,607).

The single-thread test shows the smallest gap at 25%, with AMD scoring 4,461 versus Intel's 3,568. This is still a substantial margin for a single-core workload, suggesting the Zen 5 core has a significant IPC advantage over the Bartlett Lake core at similar boost frequencies. Prime number finding runs 130.7% ahead (323 versus 140), a result that reflects the AMD core's ability to sustain high integer throughput over a prolonged calculation.

All 11 head-to-head benchmarks favor AMD, with deltas ranging from 25% to 217.1%. The consistency of the results indicates a systematic architectural advantage rather than workload-specific quirks. The Intel Core 7 251TE remains a functional processor for its intended desktop segment, but against the Ryzen 9 9850HX, the recorded data shows no competitive overlap.
