Architecture Differences

The architecture differences between these two processors are fundamental. The AMD Ryzen 9 PRO 8945HS is built on the Zen 4 architecture, using the Hawk Point codename, and is manufactured on a 4 nm process at TSMC. The Intel Arc G3 is from the Panther Lake codename, uses a 3 nm process at Intel, and its architecture is listed as null in the database. The AMD chip integrates 25,000 million transistors on a 178 mm² die, while the Intel chip's transistor count and die size are not recorded.

The cache hierarchies also differ. The AMD processor allocates 64 KB of L1 cache per core, 1 MB of L2 cache per core, and has a 16 MB shared L3 cache. The Intel Arc G3 uses a larger cache allocation per core, with 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, but its shared L3 cache is 18 MB, which is only slightly larger than the AMD's. The Intel part supports ECC memory, while the Intel Arc G3 does not. The memory interfaces also differ, with the AMD processor using DDR5 and the Intel Arc G3 using LPDDR5X. Their PCIe capabilities are also distinct, with the AMD processor offering Gen 4 with 20 lanes (CPU only) and the Intel processor offering Gen 5 with 4 lanes (CPU only).

The Verdict

The data indicates a clear performance hierarchy between these two processors. The AMD Ryzen 9 PRO 8945HS is positioned as a high-performance mobile processor, evidenced by its 8-core, 16-thread configuration, high 5.20 GHz boost clock, and 45 TDP. Its 88th percentile ranking across all CPUs and an average benchmark score of 41,963 confirm its capability for demanding tasks. In contrast, the Intel Arc G3, with its 14 cores and 14 threads, lower 4.60 GHz boost clock, and 25 TDP, is designed for a more power-efficient role. Its 50th percentile ranking and lack of benchmark data suggest it is not intended for the same performance tier.

For workloads that rely on high single-thread performance and multithreaded throughput, the AMD Ryzen 9 PRO 8945HS is the clear choice based on its higher clock speeds, SMT support, and substantial benchmark scores. The Intel Arc G3 has no recorded benchmark wins and its average score is zero, making direct performance comparisons impossible. The Intel part's advantages are in its lower power consumption (25 TDP vs 45 TDP), higher memory bandwidth (136.5 GB/s vs 89.6 GB/s), and more modern process node (3 nm vs 4 nm). However, from a pure performance standpoint, the database only has data supporting the AMD processor.

Specification Differences

The specification sheets for these two mobile processors show several key differences. The AMD Ryzen 9 PRO 8945HS has 8 cores and 16 threads, while the Intel Arc G3 has 14 cores and 14 threads. The AMD base clock is 4.00 GHz versus the Intel's 1.90 GHz. The AMD boost clock is 5.20 GHz versus the Intel's 4.60 GHz. The AMD TDP is 45 watts, while the Intel TDP is 25 watts. The AMD processor uses an AMD Socket FP7, while the Intel uses an Intel BGA 2540 socket.

The cache configurations also differ. The AMD processor has 64 KB of L1 and 1 MB of L2 per core, with 16 MB of shared L3. The Intel processor has 192 KB of L1 and 2.5 MB of L2 per core, with 18 MB of shared L3. The AMD supports DDR5 memory, while Intel supports LPDDR5X. The AMD memory bandwidth is 89.6 GB/s, while the Intel is 136.5 GB/s. The AMD supports ECC memory, while the Intel does not. The AMD PCIe interface is Gen 4 with 20 lanes, while the Intel is Gen 5 with 4 lanes. The integrated graphics differ, with AMD using Radeon 780M and Intel using Arc B370. The process node is 4 nm for AMD and 3 nm for Intel. The AMD processor has a part number of 100-000001314(FP7r2),100-000001386(FP7), while the Intel part is SA4QZ. The AMD processor is from the 8000 series, while the Intel's series is null.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Ryzen 9 PRO 8945HS and the Intel Arc G3. Consequently, there are no recorded wins for either processor, and the winsA and winsB counts are both 0. The Intel Arc G3 has no benchmarks listed in its profile, which prevents any direct comparison of scores.

The AMD Ryzen 9 PRO 8945HS, however, has a comprehensive set of benchmark scores. In Cinebench tests, it scores 25,165 in R23 multicore and 3,552 in R23 singlecore. In PassMark tests, it scores 103,390 in integer math, 63,490 in floating point math, and 30,378 in multithread. Its single-thread score is 3,920. These scores position it at the 88th percentile of all CPUs. Without any data for the Intel Arc G3, no relative performance analysis can be made between the two. The only conclusion the data supports is that the AMD processor has a robust benchmark profile, while the Intel processor has none.

Where Each One Wins

Based on the recorded data, the AMD Ryzen 9 PRO 8945HS wins in all measurable performance categories because the Intel Arc G3 has no benchmark scores. The AMD processor's strengths are its high clock speeds, with a 5.20 GHz boost, and its multithreading capability via 16 threads. This makes it suitable for tasks that are known to be sensitive to single-core speed and multi-threaded workloads, as indicated by its Cinebench R23 scores of 3,552 single-core and 25,165 multi-core.

The Intel Arc G3's advantages are not in benchmark scores but in its physical and power characteristics. It has a lower TDP of 25 watts compared to the AMD's 45 watts, suggesting it is designed for cooler, more power-efficient operation. It also provides a higher memory bandwidth of 136.5 GB/s and uses a more advanced 3 nm process node. Its 14 physical cores, without hyperthreading, and its Arc B370 integrated graphics indicate a different design philosophy focused on efficiency and integrated performance. In the absence of benchmark data, the Intel Arc G3 cannot be said to win any performance tests, but its specification sheet points to a role in power-constrained mobile environments.
