AMD Ryzen 9 8945HX vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded database contains a substantial set of benchmark results for the AMD Ryzen 9 8945HX, while the Intel Arc G3 currently has no benchmark entries. This means a direct score-by-score comparison is not possible from the available measurements. The Ryzen 9 8945HX's performance profile must therefore be analyzed against its own benchmark suite and its nearest rivals in the database.

The Ryzen 9 8945HX posts an average benchmark score of 76,212 across its recorded tests. This places it at the 95th percentile among all CPUs in the database. Its closest rivals, based on average score, are the Intel Core Ultra 9 285HX at 76,155 (a delta of 0.1% in favor of the AMD part), the AMD EPYC Embedded 8224P at 76,492 (0.4% behind), the AMD Ryzen Threadripper PRO 9945WX at 76,513 (0.4% behind), and the AMD Ryzen 9 9950X3D at 75,779 (0.6% ahead). The margins are extremely tight, with less than one percentage point separating all four rivals.

In Cinebench R23 multi-core, the Ryzen 9 8945HX scores 42,713, which is a strong result for a 55 W mobile processor. Its single-core score in the same test is 6,030. Cinebench R20 multi-core shows 17,939 and single-core 2,532. In Cinebench R15, the multi-core result is 4,305 and single-core is 607. These Cinebench numbers indicate a processor that scales well across all cores while maintaining competitive single-thread performance.

PassMark results for the Ryzen 9 8945HX show particular strengths in specific workloads. The multithread score is 51,405, while single-thread is 3,907. Integer math scores 195,180, and floating-point math scores 117,453. Data compression reaches 677,755, while data encryption is 40,836.

Architecture Differences

The Ryzen 9 8945HX uses the Zen 4 architecture under the codename Dragon Range, fabricated on a 5 nm process by TSMC. It has 16 cores and 32 threads, with a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The design uses 13,140 million transistors across a die size of 2x 71 mm². Cache is organized as 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 total. The socket is AMD Socket FL1.

The Intel Arc G3 uses the Panther Lake codename, fabricated on a 3 nm process by Intel. It has 14 cores and 14 threads, meaning no simultaneous multithreading. Base clock is 1.90 GHz and boost is 4.60 GHz. L1 cache is 192 KB per core, L2 is 2.5 MB per core, and L3 is 18 MB shared. The socket is Intel BGA 2540. The process node advantage goes to Intel at 3 nm versus AMD's 5 nm, but the AMD part has a higher transistor count at 13,140 million, while the Intel part has no transistor or die size data recorded.

The Ryzen 9 8945HX has an unlocked multiplier, while the Arc G3 is locked. The AMD part supports PCIe Gen 5 with 28 lanes (CPU only), whereas the Arc G3 supports PCIe Gen 5 with only 4 lanes (CPU only). This is a substantial difference in expansion capability.

The integrated graphics differ: the Ryzen 9 8945HX uses Radeon 610M, while the Arc G3 uses Arc B370. Both are mobile parts, and both use dual-channel memory, but the memory types differ.

The Ryzen 9 8945HX has more cores, more threads, higher clocks, and a higher TDP. The Arc G3 has a smaller process node, higher per-core L1 and L2 cache, higher memory bandwidth, and a later release date. The AMD part has significantly more PCIe lanes and an unlocked multiplier.

Where Each One Wins

The AMD Ryzen 9 8945HX demonstrates clear strengths in multi-threaded workloads based on its benchmark results. The Cinebench R23 multi-core score of 42,713, combined with 16 cores and 32 threads, positions it strongly for rendering, compilation, and other parallel tasks. The PassMark multithread score of 51,405 and integer math score of 195,180 reinforce this pattern. The high L3 cache of 64 MB and 28 PCIe Gen 5 lanes make it suitable for data-heavy workflows and systems requiring extensive expansion.

The Intel Arc G3, based on its recorded specifications, wins on power efficiency. Its 25 W TDP is less than half of the AMD part's 55 W. It also delivers higher memory bandwidth at 136.5 GB/s versus 83.2 GB/s, and uses a more advanced 3 nm process. The larger per-core L1 and L2 caches (192 KB and 2.5 MB per core) could benefit latency-sensitive single-thread tasks, though no benchmark data exists to confirm this. The 4 PCIe Gen 5 lanes limit expansion, but the lower power envelope and LPDDR5X memory support suggest a design aimed at thinner, more power-constrained mobile systems.

Given the absence of benchmark data for the Arc G3, the database cannot confirm any performance-based wins for that part. The Ryzen 9 8945HX has a complete recorded performance profile and sits at the 95th percentile of all CPUs. Its nearest rivals, all within 0.6% in average score, are desktop-class or high-end mobile parts, which indicates that the 8945HX competes above its mobile segment. For users prioritizing measured performance in multi-threaded and single-threaded tasks, the Ryzen 9 8945HX is the only part with recorded evidence. For users prioritizing low power draw, the Arc G3's 25 W TDP and 3 nm process are the only data-supported advantages, but no performance verification exists in the database.
