Architecture Differences

The Ryzen 9 9950X3D uses AMD's Zen 5 architecture, codenamed Granite Ridge, built on a 4 nm process at TSMC. It packs 16,630 million transistors across a dual-chiplet design with a die size of 2x 70.6 mm². The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a substantial 128 MB of L3 cache. This large L3 pool is a defining feature for gaming and data-heavy workloads. The processor supports DDR5 memory over a dual-channel bus, delivering 89.6 GB/s of bandwidth. It also enables ECC memory, a feature absent on the Intel part. The integrated graphics are labeled simply as Radeon Graphics, and the CPU provides 24 PCIe Gen 5 lanes. The socket is AMD Socket AM5, and the multiplier is unlocked, allowing overclocking.

The Intel Arc G3 uses the Panther Lake codename and is fabricated on Intel's own 3 nm process node. It has 14 cores and 14 threads, with no simultaneous multithreading. The cache layout differs markedly: 192 KB of L1 per core, 2.5 MB of L2 per core, and only 18 MB of shared L3. This is a smaller total cache compared to the Ryzen's 128 MB L3. Memory support is LPDDR5X over a dual-channel bus, with a higher bandwidth figure of 136.5 GB/s. The integrated graphics are Arc B370, a more capable GPU than the basic Radeon Graphics on the AMD chip. The Intel part supports only 4 PCIe Gen 5 lanes, reflecting its mobile, power-constrained design. The socket is Intel BGA 2540, meaning it is permanently attached to the motherboard. The multiplier is locked, preventing overclocking. ECC memory is not supported.

The process node difference is notable: Intel uses 3 nm versus AMD's 4 nm, though both are advanced nodes. The transistor count and die size for the Intel part are not recorded in the database, so a direct comparison is impossible. The core counts differ by two cores, but the thread count difference is larger: 32 threads on the AMD versus 14 on the Intel. This gap comes from AMD's simultaneous multithreading, which the Intel part lacks.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the AMD Ryzen 9 9950X3D against the Intel Arc G3, and the Arc G3 has zero recorded benchmark scores. Therefore, direct numeric comparison is impossible. However, the Ryzen 9 9950X3D's individual benchmark results provide a clear picture of its capability. In Cinebench R23 multi-core, it scores 42,018, which is a strong indicator of parallel workload performance. Its single-core score in the same test is 2,259. In Geekbench, the multi-core score is 26,736 and the single-core score is 3,064. The 3DMark tests show scaling across thread counts: 2,549 for 2 threads, 4,963 for 4 threads, 9,259 for 8 threads, 16,374 for 16 threads, and 17,184 for max threads. This progression shows near-linear scaling up to 16 threads, with diminishing returns beyond that point.

The PassMark suite adds more detail. Multi-thread score is 70,255, single-thread is 4,737, integer math is 243,209, floating-point math is 159,724, and extended instructions score 73,011. Data compression reaches 908,421, and data encryption scores 44,536. Prime number finding yields 613, random string sorting hits 95,423, and physics scores 5,670. These numbers indicate a processor that excels in arithmetic, encryption, and compression tasks. The Arc G3's absence from the benchmark database means no such figures exist for it. The data can only show that the Ryzen 9 9950X3D is a high-scoring part, while the Arc G3's performance remains unmeasured in this database.
