AMD Ryzen 9 9955HX3D vs Intel Core 7 253PTE Comparison

The AMD Ryzen 9 9955HX3D and Intel Core 7 253PTE occupy different corners of the processor market, one a 16-core mobile flagship and the other a 10-core desktop part. The benchmark data shows a decisive overall victory for the AMD processor, which wins 14 of the 15 recorded head-to-head tests, while the Intel chip claims only a single win. The magnitude of the AMD advantage varies dramatically by workload, ranging from a modest 9.9% lead in one single-core test to a staggering 540.2% lead in prime number calculation.

Where Each One Wins

The AMD Ryzen 9 9955HX3D dominates almost every category of the recorded benchmarks. Its largest victories come in compute-heavy tasks: the PassMark find prime numbers test shows a 540.2% advantage, extended instructions show a 267.3% lead, and physics simulation scores 255.6% higher. These results indicate a processor built for sustained multi-threaded throughput, with the 16-core, 32-thread configuration delivering 150.4% higher PassMark multithread scores and 181.8% higher Cinebench R15 multicore results. The AMD chip also leads in data compression by 184.9%, random string sorting by 195.8%, and data encryption by 154.5%.

The Intel Core 7 253PTE wins exactly one benchmark: Cinebench R23 single-core. Its score of 3003 beats the AMD score of 2159.5 by 28.1%. This single result suggests the Intel architecture excels in lightly threaded, short-duration workloads where its higher single-core Cinebench R23 output matters. However, the AMD processor wins the other single-threaded test, PassMark single thread, by 18.9% with a score of 4511 versus 3794. The data therefore shows a split in single-core performance depending on the benchmark methodology, with Intel winning the Cinebench R23 variant but losing the PassMark variant.

For multi-core rendering, the choice is clear. The AMD part delivers 79.4% higher Cinebench R23 multicore scores, 181.8% higher R15 multicore scores, and 86.1% higher integer math results. Workloads that scale across cores, such as video encoding, 3D rendering, and compilation, will favor the AMD processor by wide margins.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 9 9955HX3D belongs to the 9000 series, uses the Zen 5 architecture with the Fire Range codename, and is fabricated on a 4 nm process at TSMC. It packs 16 cores and 32 threads with a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The chip contains 16,630 million transistors across a dual-chiplet design with a die size of 2x 70.6 mm². Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a large 128 MB L3 cache. The TDP is rated at 55 watts, and the processor uses AMD Socket FL1. It supports DDR5 memory on a dual-channel bus with 89.6 GB/s of memory bandwidth and ECC memory. PCI Express connectivity includes Gen 5 with 28 lanes from the CPU. Integrated graphics come from the Radeon 610M. The multiplier is unlocked, and the part number is 100-000001030.

The Intel Core 7 253PTE is a desktop processor with the Bartlett Lake codename, built by Intel on a 10 nm process. It has 10 cores and 20 threads, a base clock of 1.80 GHz, and a boost clock of 5.40 GHz. The cache arrangement differs notably: 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The TDP is 45 watts, lower than the AMD part. It uses Intel Socket 1700 and supports both DDR4 and DDR5 memory, still on a dual-channel bus with the same 89.6 GB/s memory bandwidth and ECC support. PCIe connectivity is Gen 5 with 16 lanes from the CPU, fewer than the AMD part. Integrated graphics come from UHD Graphics 730. The multiplier is locked. The launch MSRP is $384.

The process node difference is substantial: 4 nm at TSMC for AMD versus 10 nm at Intel. The AMD chip also has nearly four times the L3 cache (128 MB versus 33 MB), which helps explain its dominance in cache-sensitive workloads like data compression and random string sorting. The Intel chip has twice the L2 per core (2 MB versus 1 MB), but the overall cache capacity favors AMD. The release dates differ by over a year, with the AMD part appearing in January 2025 and the Intel part in March 2026, though the production status for both is active.

The Verdict

The recorded data indicates the AMD Ryzen 9 9955HX3D is the stronger processor for almost any compute workload. Its average benchmark score of 97453 places it in the 96th percentile of all CPUs, while the Intel Core 7 253PTE averages 34962 and sits in the 84th percentile. The AMD chip's nearest rivals include the AMD Ryzen Threadripper PRO 5965WX, which scores 98504 for a 1.1% difference, and the AMD Ryzen 9 PRO 9945 at 96083, a 1.4% gap. The Intel chip's nearest rivals are the Intel Core i7-13800H at 34988, a 0.1% difference, and the Intel Core i9-12900HX at 35003, also a 0.1% difference.

For users running multi-core rendering, data processing, encryption, physics simulation, or floating-point math, the AMD processor is the clear choice based on the benchmark results. The 16-core configuration delivers more than double the multithread performance of the Intel part in several tests. The AMD chip also wins the PassMark single-thread test, so even in lightly threaded scenarios it holds an advantage in that specific measurement.

The Intel Core 7 253PTE is competitive only in the Cinebench R23 single-core test, where it leads by 28.1%. Users whose primary workload is single-threaded Cinebench R23 rendering might see better results with the Intel part, but the data shows this is the exception rather than the rule. The Intel chip also offers a lower TDP of 45 watts versus 55 watts, which may matter for power-constrained systems, and it supports DDR4 memory in addition to DDR5, which could simplify upgrades in existing systems. However, the benchmark data overwhelmingly favors the AMD processor across rendering, math, compression, encryption, and physics workloads.
