Where Each One Wins

The AMD Ryzen 9 8945HX wins in every recorded category, but the size of the win varies significantly by workload type. The largest advantages come in tasks that stress parallel integer work, instruction set extensions, and memory compression. The prime number test (219.5% delta), extended instructions test (191.4% delta), and random string sorting test (179.1% delta) are the strongest areas for AMD.

The encryption test also shows a very large gap at 163.5%, which suggests the AMD part has a notable edge in cryptographic throughput. Data compression shows a 145.7% advantage. The multithread test shows a 105.4% advantage, and the Cinebench multicore tests all show approximately 100.8% advantages.

The areas where the Intel Core 7 253PTE is least far behind are the single-thread integer-style workloads. The PassMark single-thread test shows only a 3% gap, and the floating point math test shows a 74.8% gap, which is the second smallest delta. The physics test (64.5%) and integer math test (63.3%) are also among the smaller gaps, though still decisive for AMD.

For users prioritizing single-thread responsiveness, the Intel part is competitive in that narrow slice of the data. For any multi-threaded, encryption, compression, or extended instruction workload, the AMD part holds an overwhelming lead. The database shows a clear split: the AMD Ryzen 9 8945HX dominates all measured throughput-oriented tasks, while the Intel Core 7 253PTE keeps the single-thread gap relatively modest.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen 9 8945HX has 16 cores and 32 threads, while the Intel Core 7 253PTE has 10 cores and 20 threads. The base clock differs substantially: AMD runs at 2.50 GHz, Intel at 1.80 GHz. Both parts share the same boost clock of 5.40 GHz.

Thermal design power differs by 10 watts, with AMD at 55 W and Intel at 45 W. The AMD part uses AMD Socket FL1, while Intel uses Intel Socket 1700. The AMD processor has an unlocked multiplier, whereas the Intel processor does not.

Cache configurations differ in structure. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. This means Intel has more per-core L1 and L2, but AMD has nearly double the total L3 capacity.

Memory support differs as well. The AMD processor supports only DDR5, while the Intel processor supports both DDR4 and DDR5. Both use dual-channel memory buses, but the recorded memory bandwidth is higher for Intel at 89.6 GB/s versus 83.2 GB/s for AMD. The Intel part supports ECC memory, while the AMD part does not.

PCIe lane counts also differ. The AMD processor provides 28 PCIe Gen 5 lanes, while the Intel processor provides 16 PCIe Gen 5 lanes. The integrated graphics differ: AMD uses Radeon 610M, Intel uses UHD Graphics 730.

The AMD part is classified as a mobile segment processor, while the Intel part is classified as desktop. The AMD part has a recorded production status of Active and a release date of 2025-04-22.

Architecture Differences

The AMD Ryzen 9 8945HX uses the Zen 4 architecture under the Dragon Range codename, part of the 8000 series. It is fabricated on a 5 nm process at TSMC, with 13,140 million transistors and a die size of 2x 71 mm². The Intel Core 7 253PTE uses the Bartlett Lake codename, part of the Core 7 generation. It is fabricated on a 10 nm process at Intel, with no recorded transistor count or die size.

The manufacturing process difference is significant: 5 nm versus 10 nm. This process gap likely contributes to the AMD part's higher transistor count and its ability to pack 16 cores into a mobile package. The AMD design uses a chiplet approach, as indicated by the 2x 71 mm² die size, while the Intel design has no recorded die size breakdown.

The architecture generation names reflect different design philosophies. AMD's Zen 4 is a mature high-performance core design, while Bartlett Lake represents Intel's hybrid approach for desktop parts. The AMD part's codename, Dragon Range, indicates a high-end mobile HX-class product. The Intel part's codename, Bartlett Lake, ties it to the desktop lineup.

The cache architecture differs in allocation. AMD dedicates 1 MB of L2 per core and a large 64 MB shared L3. Intel dedicates 2 MB of L2 per core but only 33 MB of shared L3. This means Intel has more private cache per core, but AMD has a much larger shared pool, which may explain the large advantages in data compression and random string sorting tests.

The memory controller also differs. AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Despite this, Intel records a slightly higher memory bandwidth figure (89.6 GB/s versus 83.2 GB/s). The AMD part has more PCIe lanes (28 versus 16), which may matter for systems with multiple high-speed devices.

The integrated graphics differ in brand and model. AMD uses the Radeon 610M, Intel uses UHD Graphics 730. Neither part is primarily known for its iGPU, but the difference is recorded in the database.

The Verdict

The recorded data shows the AMD Ryzen 9 8945HX as the clearly stronger processor in nearly every measured workload. The 16-core, 32-thread configuration with a 5.40 GHz boost clock and 64 MB of L3 cache delivers scores that are roughly double the Intel Core 7 253PTE in multi-threaded tests. The average benchmark score of 76,212 versus 34,962 places the AMD part far above the Intel part in the overall ranking, with the 95th percentile versus 84th percentile gap confirming the separation.

The Intel Core 7 253PTE does have a few recorded advantages. It supports both DDR4 and DDR5 memory, has ECC memory support, and records a higher memory bandwidth figure. It also has more L1 and L2 cache per core. The single-thread PassMark test shows only a 3% gap, which indicates that the Intel part is not entirely outclassed in lightly threaded scenarios. However, none of these advantages translate into a benchmark win in the recorded data.

For users selecting based on the database measurements, the AMD Ryzen 9 8945HX is the choice for any workload involving multi-threading, compression, encryption, or extended instructions. The Intel Core 7 253PTE is the choice only for those who specifically need DDR4 memory support, ECC memory, or a desktop socket platform. The benchmark results do not show any workload where the Intel part wins outright.

The AMD part's unlocked multiplier and higher base clock (2.50 GHz versus 1.80 GHz) add to its appeal in the recorded data, though the Intel part has a lower TDP (45 W versus 55 W). The Intel part's launch MSRP is listed at $384, but the database does not record a launch MSRP for the AMD part, so a direct price comparison is not possible from the available data.

The verdict from the measurements is unambiguous: the AMD Ryzen 9 8945HX dominates the Intel Core 7 253PTE across the entire benchmark suite, with the only competitive result being a narrow 3% gap in single-thread PassMark performance.
