The Verdict

The data presents a clear split based on workload type. The Intel Xeon 6724P is the choice for compute-heavy, floating-point, and physics-based tasks. It wins 10 out of 17 head-to-head benchmarks, including every Cinebench rendering test and a decisive 56.7% lead in PassMark physics. If your work involves simulation, scientific computing, or any workload that stresses FPU throughput, the Xeon's 135404 floating-point score versus the AMD's 117453 makes it the practical pick.

The AMD Ryzen 9 8945HX, conversely, is better for integer-heavy and data-processing tasks. It wins 7 benchmarks, with notable 19.2% and 18.9% leads in single-thread and encryption, respectively. Its 195180 integer math score outpaces the Xeon's 172216 by 13.3%. For developers, database workloads, or general productivity where integer operations dominate, the AMD part delivers more throughput.

The overall database percentiles are close: AMD sits at 95 and Intel at 94. However, the AMD has a higher average benchmark score (76212 vs 72396). The Xeon's nearest rival is the Intel Xeon 6517P (0.1% delta), while the AMD's closest competitor is the Intel Core Ultra 9 285HX (0.1% delta). Choose the Xeon for raw compute density in a server rack; choose the Ryzen for a mobile platform with strong integer and single-thread performance.

Head-to-Head Benchmarks

The Intel Xeon 6724P sweeps the Cinebench suite. Across R15, R20, and R23, both multi-core and single-core, the Xeon wins by exactly 2.1% each time. The R23 multi-core score of 43643 versus 42713 shows a modest but consistent edge in rendering tasks. The Xeon also wins PassMark extended instructions (54101 vs 49823, a 7.9% lead) and floating-point math (135404 vs 117453, a 13.3% lead). The most lopsided result is PassMark physics, where the Xeon scores 5004 against the AMD's 2168, a 56.7% difference.

The AMD Ryzen 9 8945HX takes the PassMark single-thread test by a wide margin: 3907 versus 3279, a 19.2% advantage. It also leads in data encryption (40836 vs 34332, an 18.9% delta) and random string sorting (78781 vs 68477, a 15% delta). In integer math, the AMD wins with 195180 versus 172216, a 13.3% lead. The multithread test is essentially a tie, with the AMD ahead by just 0.1% (51405 vs 51345). Data compression also favors AMD: 677755 versus 627185, an 8.1% win.

The pattern is unmistakable. The Xeon wins on raw compute throughput, especially in floating-point and physics. The AMD wins on memory-sensitive data tasks and single-thread responsiveness. The Xeon takes 10 wins, the AMD takes 7.

Specification Differences

The two CPUs diverge significantly in platform design. The AMD Ryzen 9 8945HX uses AMD Socket FL1, while the Intel Xeon 6724P uses Intel Socket 4710. The AMD has a TDP of 55 watts, whereas the Intel part is rated at 210 watts. Base clocks differ: the AMD runs at 2.50 GHz, the Intel at 3.60 GHz. Boost clocks flip the advantage: the AMD boosts to 5.40 GHz, the Intel to 4.30 GHz.

Memory bandwidth is a major differentiator. The AMD supports dual-channel DDR5 with 83.2 GB/s bandwidth. The Intel supports eight-channel DDR5 with 409.6 GB/s bandwidth, a massive increase for memory-hungry server workloads. ECC memory is supported on the Intel but not the AMD.

PCIe lanes also differ: the AMD offers Gen 5 with 28 lanes (CPU only), while the Intel offers Gen 5 with 88 lanes (CPU only). The AMD has integrated graphics (Radeon 610M), while the Intel has no integrated graphics (N/A). The AMD has an unlocked multiplier; the Intel does not. The AMD's part number is 100-000001848; the Intel's is SRVUA.

Architecture Differences

The AMD Ryzen 9 8945HX is built on Zen 4 architecture with the codename Dragon Range, part of the Ryzen 9 generation. It uses a 5 nm process from TSMC, with 13,140 million transistors and a die size of 2x 71 mm². Its cache layout includes 64 KB L1 per core, 1 MB L2 per core, and 64 MB L3. This is a mobile-oriented design with a focus on power efficiency (55 W TDP).

The Intel Xeon 6724P is built on Granite Rapids architecture, part of the Xeon 6 generation (Granite Rapids-SP). It also uses a 5 nm process, but from Intel's own foundry. The cache differs: 112 KB L1 per core, 2 MB L2 per core, and 72 MB of shared L3. This is a server-class design with a 210 W TDP, optimized for sustained multi-threaded throughput and high memory bandwidth.

The architectural split is clear: AMD's Zen 4 focuses on high boost clocks and per-core efficiency, while Intel's Granite Rapids focuses on massive memory bandwidth (409.6 GB/s vs 83.2 GB/s) and higher base clocks. The AMD has no v-cache, and the Intel has no 3D V-Cache either. The AMD's 16 cores are on a mobile socket; the Intel's 16 cores are on a server platform with 88 PCIe lanes.

Where Each One Wins

The AMD Ryzen 9 8945HX wins in scenarios that favor integer operations, single-thread speed, and data manipulation. Its 19.2% single-thread lead (3907 vs 3279) makes it better for lightly threaded applications, interactive workloads, and legacy software that relies on one or two cores. The 18.9% encryption advantage (40836 vs 34332) points to better cryptographic performance, useful for VPNs, secure communications, or database encryption. The 13.3% integer math lead (195180 vs 172216) helps in compression, sorting, and general business logic. Its 15% random string sorting lead (78781 vs 68477) reinforces a strength in text processing and data serialization. The 8.1% data compression win (677755 vs 627185) makes it the pick for archive creation or storage systems.

The Intel Xeon 6724P wins in compute-heavy, floating-point, and physics workloads. Its 56.7% physics lead (5004 vs 2168) is staggering, making it the obvious choice for simulation, finite element analysis, or any physics engine. The 13.3% floating-point math win (135404 vs 117453) supports scientific computing and 3D rendering. The 7.9% extended instructions lead (54101 vs 49823) helps in AVX-512-heavy code, common in AI inference and scientific libraries. All six Cinebench wins (each by 2.1%) show consistent multi-threaded rendering strength, ideal for video encoding or 3D animation. The Xeon's 409.6 GB/s memory bandwidth versus the AMD's 83.2 GB/s, combined with ECC support, makes it the server-grade choice for memory-bound data centers.

In short, the AMD is a mobile workhorse for integer and single-thread tasks. The Intel is a server powerhouse for floating-point, physics, and memory-intensive computing. Pick based on your workload's dominant arithmetic type, not on core count, since both offer 16 cores and 32 threads.
