AMD Ryzen 9 9950X3D vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The AMD Ryzen 9 9950X3D wins every single head-to-head benchmark recorded in the database. The Intel Arc G3 EXTREME does not record a single victory across the 15 compared tests. The margin is not uniform, however, and the data reveals where the gap is narrow and where it becomes a rout.

The largest advantage appears in synthetic integer throughput. In PassMark integer math, the Ryzen 9 9950X3D scores 243,209 against 71,164 for the Arc G3 EXTREME, a delta of 241.8%. That is the single biggest percentage gap in the comparison. Extended instruction workloads tell a similar story: 73,011 versus 24,017, a 204% advantage. Data compression follows at 195.8% (908,421 versus 307,094), and Cinebench R15 multi-core shows 198.2% (6,536 versus 2,192). These four tests all exceed a 190% lead, indicating that the AMD part is in a different performance class when many cores are active and instructions are complex.

Multi-threaded rendering confirms the pattern. Cinebench R23 multi-core gives the Ryzen 9 9950X3D a score of 42,018, while the Intel part manages 14,655, a 186.7% delta. The PassMark multi-thread score is 70,255 versus 30,659, a 129.1% advantage. PassMark physics shows 5,670 versus 2,515, a 125.4% lead. Random string sorting is 95,423 versus 37,331, a 155.6% gap. Every one of these workloads relies on sustained parallel execution, and the AMD processor's 16 cores and 32 threads dominate the Intel part's 14 cores and 14 threads.

The narrowest margin is in single-threaded performance. PassMark single-thread scores are 4,737 for the AMD part and 4,293 for the Intel part, a delta of only 10.3%. Cinebench R23 single-core shows 2,259 versus 1,862, a 21.3% gap, and Cinebench R15 single-core is 350 versus 267, a 31.1% delta. These results indicate that in lightly threaded tasks, the Intel Arc G3 EXTREME is far more competitive than in multi-threaded workloads, though it still loses every test. The gap narrows as thread count drops, which suggests the Intel part's per-core efficiency is respectable even if its core count and thread support limit it.

The remaining workloads are also decisive wins for AMD. PassMark floating-point math: 159,724 versus 86,929, an 83.7% lead. PassMark data encryption: 44,536 versus 23,881, an 86.5% lead. PassMark find prime numbers: 613 versus 248, a 147.2% lead. In no recorded benchmark does the Intel part come within single digits of the AMD part except for the PassMark single-thread tests.

Architecture Differences

The two processors are built on fundamentally different platforms, and the database records substantial architectural divergence. The AMD Ryzen 9 9950X3D uses the Zen 5 architecture with the Granite Ridge codename, fabricated on a 4 nm process at TSMC. The Intel Arc G3 EXTREME uses the Panther Lake codename on a 3 nm process at Intel's own foundry. The process nodes are close, but the transistor counts are not comparable: the AMD part lists 16,630 million transistors on a die size of 2x 70.6 mm², while the Intel part has no recorded transistor count or die size.

Core counts differ notably. The AMD processor has 16 cores and 32 threads, while the Intel part has 14 cores and 14 threads. The lack of hyperthreading on the Intel side is a decisive factor in multi-threaded benchmarks. Cache hierarchies also diverge sharply. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The AMD L3 cache is more than seven times larger, which explains its strength in data-heavy workloads.

Memory support is another major difference. The AMD processor supports DDR5 memory on a dual-channel bus with 89.6 GB/s bandwidth. The Intel part supports LPDDR5X on a dual-channel bus with 136.5 GB/s bandwidth, which is 52% higher. This gives the Intel part a memory bandwidth advantage, yet it does not translate into benchmark wins in the recorded tests. The AMD part also supports ECC memory; the Intel part does not.

PCIe lane counts are reversed in scale. The AMD processor provides Gen 5 with 24 lanes (CPU only), while the Intel part provides Gen 5 with only 4 lanes (CPU only). The AMD part is a desktop component on AMD Socket AM5, with an unlocked multiplier and integrated Radeon Graphics. The Intel part is a mobile component on Intel BGA 2540, with a locked multiplier and integrated Arc B390 graphics. The AMD part's release date is 2025-01-05, while the Intel part's release date is 2026-05-27, placing the Intel part over a year later in the timeline. The AMD part has a launch MSRP of $699; the Intel part has no recorded launch MSRP.

Where Each One Wins

The AMD Ryzen 9 9950X3D wins everywhere in the recorded data, but the scale of the win varies by workload type. Its largest leads come in integer math, extended instructions, and data compression, all of which benefit from high core counts and large caches. The 241.8% lead in integer math and the 204% lead in extended instructions indicate that compute-heavy parallel workloads are the AMD part's home turf. The 195.8% lead in data compression and the 155.6% lead in random string sorting further confirm that cache-sensitive data manipulation is a strength.

Multi-threaded rendering is also a clear AMD strength. The 186.7% lead in Cinebench R23 multi-core and the 198.2% lead in Cinebench R15 multi-core show that 16 cores and 32 threads outperform 14 cores and 14 threads by a wide margin in rendering workloads. The PassMark multi-thread score of 70,255 versus 30,659 reinforces this. Physics simulation, at 125.4% ahead, follows the same pattern.

The Intel Arc G3 EXTREME's best relative showing is in single-threaded tests. The PassMark single-thread delta is only 10.3%, which is the closest result in the entire comparison. Cinebench R23 single-core at 21.3% and Cinebench R15 single-core at 31.1% are also the smaller gaps. This indicates that the Intel part's individual cores are reasonably efficient, but the platform cannot scale to match the AMD part when more threads are active. The Intel part's higher memory bandwidth (136.5 GB/s versus 89.6 GB/s) does not appear in any benchmark win, so the practical benefit of that bandwidth is not evident in the recorded scores.

The Intel part also has a process node advantage at 3 nm versus 4 nm, and a lower TDP of 25 watts versus 170 watts. That power difference is substantial, but the database records no power efficiency benchmark, so the only measurable conclusion is that the Intel part is a mobile-class chip with a much lower thermal envelope.

The Verdict

The data is unambiguous. The AMD Ryzen 9 9950X3D wins all 15 head-to-head benchmarks, with an average benchmark score of 75,779 compared to 36,699 for the Intel Arc G3 EXTREME. The AMD part sits at the 95th percentile of all CPUs, while the Intel part sits at the 85th percentile. The nearest rivals for the AMD part are the AMD Ryzen 7 PRO 9755 at a 0.1% lower average score, the AMD Ryzen 7 PRO 9755X3D at 0.1% lower, the AMD EPYC 8224P at 0.3% lower, and the Intel Core Ultra 9 285 at 0.4% lower. These are all close competitors, indicating the Ryzen 9 9950X3D is at the top of a tight cluster of high-end processors.

The Intel Arc G3 EXTREME's nearest rivals are the Intel Core Ultra 5 225 at 0.6% higher average score, the AMD Ryzen 5 5600F at 0.7% higher, the AMD Ryzen 5 5500X3D at 0.9% higher, and the AMD Ryzen AI 7 PRO 450 at 1.1% higher. This places the Intel part in a mid-range performance tier, despite its later release date and smaller process node. The AMD part is 106.5% faster on average, a difference that dwarfs the gaps between each part and its own nearest rivals.

The practical verdict is that the AMD Ryzen 9 9950X3D is a high-end desktop processor that dominates in multi-threaded and cache-sensitive workloads. The Intel Arc G3 EXTREME is a mobile processor with a much lower power target and a competitive single-thread showing, but it cannot match the AMD part in any recorded test. The choice between them is not a performance trade-off; it is a platform decision. The AMD part is for desktop systems with AM5 sockets, while the Intel part is for mobile systems with BGA 2540 sockets. The data does not support any scenario where the Intel part wins a performance comparison.
