AMD Ryzen 9 9900X3D vs Intel Arc G3 EXTREME Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep: the AMD Ryzen 9 9900X3D wins all 17 head-to-head comparisons against the Intel Arc G3 EXTREME. The margin varies enormously by workload, from a narrow single-thread edge to multi-core leads that exceed 200 percent.

The largest gap appears in Cinebench R23. In the single-core run, the AMD scores 6739 against the Intel's 1862, a delta of 261.9 percent. The multi-core result is even more lopsided in absolute terms: 47737 versus 14655, a 225.7 percent advantage. Cinebench R20 tells a similar story, with the AMD ahead by 83.2 percent in both single-core (2830 versus 1545) and multi-core (20049 versus 10945) tests. Cinebench R15 shows the AMD leading by 154.3 percent in single-core (679 versus 267) and 119.5 percent in multi-core (4811 versus 2192).

PassMark workloads split into two clusters. The first cluster contains tasks where the AMD's lead is moderate. Floating point math shows the AMD at 119622 versus 86929, a 37.6 percent advantage. Data encryption shows 33282 versus 23881, a 39.4 percent lead. The second cluster contains tasks where the AMD more than doubles the Intel result. Integer math delivers 179727 versus 71164, a 152.6 percent delta. Extended instructions show 55426 versus 24017, a 130.8 percent lead. Data compression reaches 685074 versus 307094, a 123.1 percent gap. Prime number finding shows 544 versus 248, a 119.4 percent delta.

The tightest race in the entire dataset is PassMark single-thread performance. The AMD scores 4646 and the Intel scores 4293, a lead of only 8.2 percent. This is the only benchmark where the two processors are close. The same result appears under both PassMark test names, passmark_single_thread and passmark_singlethread, confirming the measurement. PassMark multithread shows 56154 versus 30659, an 83.2 percent gap. Physics shows 5340 versus 2515, a 112.3 percent lead. Random string sorting shows 71864 versus 37331, a 92.5 percent delta.

The average benchmark scores reflect this dominance. The AMD's average is 54762, while the Intel's is 36699. The AMD sits at the 91st percentile of all CPUs in the database, while the Intel sits at the 85th percentile. The AMD's nearest rivals include the Intel Core Ultra 5 245KF at a -0.6 percent delta, the Intel Core Ultra 5 245K at 1.3 percent, the Intel Xeon 6505P at 2 percent, and the Intel Core i7-14700F at 2.1 percent. The Intel Arc G3 EXTREME's nearest rivals include the Intel Core Ultra 5 225 at -0.6 percent, the AMD Ryzen 5 5600F at -0.7 percent, the AMD Ryzen 5 5500X3D at -0.9 percent, and the AMD Ryzen AI 7 PRO 450 at -1.1 percent. This places the two chips in completely different competitive tiers.

Architecture Differences

The two processors come from opposite ends of the computing spectrum. The AMD Ryzen 9 9900X3D is a desktop part on AMD Socket AM5, built on the Zen 5 architecture with the codename Granite Ridge. The Intel Arc G3 EXTREME is a mobile part on Intel BGA 2540, built on the Panther Lake codename. The AMD uses a 4 nm process from TSMC, while the Intel uses a 3 nm process from Intel's own foundry.

Core counts differ in an interesting way. The Intel has 14 cores but only 14 threads, meaning it has no simultaneous multithreading. The AMD has 12 cores and 24 threads, doubling its thread count. This explains why the AMD's multi-core lead is so much larger than its core count advantage would suggest. The AMD's base clock is 4.40 GHz and its boost clock is 5.50 GHz. The Intel's base clock is 1.90 GHz and its boost clock is 4.70 GHz. The AMD's boost clock is 0.80 GHz higher, and its base clock is dramatically higher.

Cache configurations are fundamentally different. The AMD has 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache. The Intel has 192 KB of L1 per core, 2.5 MB of L2 per core, and only 18 MB of shared L3 cache. The AMD's total L3 cache is more than seven times larger. The per-core L1 and L2 caches favor the Intel, but the massive L3 advantage belongs to the AMD.

Memory support also diverges. The AMD uses DDR5 with dual-channel memory and 89.6 GB/s bandwidth. The Intel uses LPDDR5X with dual-channel memory and 136.5 GB/s bandwidth. The Intel's memory bandwidth is higher, but the AMD supports ECC memory while the Intel does not. PCIe connectivity differs sharply: the AMD provides Gen 5 with 24 lanes from the CPU, while the Intel provides Gen 5 with only 4 lanes. The AMD's integrated graphics are Radeon Graphics, while the Intel uses Arc B390. The AMD has an unlocked multiplier, the Intel does not. The AMD's TDP is 120 watts, the Intel's is 25 watts. The AMD's transistor count is 16,630 million across a dual-die design of 2x 70.6 mm², while the Intel's transistor count and die size are not recorded in the database.

The Verdict

The data supports only one conclusion for raw performance: the AMD Ryzen 9 9900X3D is dominant across every recorded benchmark. The 17-0 win record leaves no workload category where the Intel Arc G3 EXTREME takes the lead. The AMD's 225.7 percent advantage in Cinebench R23 multi-core and 261.9 percent advantage in Cinebench R23 single-core define the scale of the gap. Its average benchmark score of 54762 versus 36699 places it in a different competitive class, confirmed by its 91st percentile rank against the Intel's 85th.

The Intel Arc G3 EXTREME does have structural advantages in the specification sheet. It uses a smaller 3 nm process, delivers higher memory bandwidth at 136.5 GB/s, and has a 25 watt TDP compared to the AMD's 120 watts. Its 14 cores exceed the AMD's 12, and its per-core L1 and L2 caches are larger. None of these translate into benchmark wins. The Intel's lack of simultaneous multithreading, with 14 threads for 14 cores, limits its multi-core ceiling. Its base clock of 1.90 GHz is far below the AMD's 4.40 GHz.

The nearest-rival data reinforces the separation. The AMD competes with desktop processors like the Intel Core i7-14700F and Intel Core Ultra 5 series, all within 2.1 percent of its average score. The Intel Arc G3 EXTREME competes with lower-tier desktop and mobile chips like the AMD Ryzen 5 5600F and AMD Ryzen AI 7 PRO 450, all within 1.1 percent. The two chips are not direct competitors; the database places them in different performance tiers.

Where Each One Wins

The AMD Ryzen 9 9900X3D wins everywhere in the benchmark suite. Its largest advantages appear in Cinebench R23, where the single-core delta reaches 261.9 percent and the multi-core delta reaches 225.7 percent. It also dominates integer math at 152.6 percent, extended instructions at 130.8 percent, data compression at 123.1 percent, prime number finding at 119.4 percent, and physics at 112.3 percent. These workloads point toward desktop productivity, content creation, and CPU-bound simulation tasks. The 128 MB L3 cache and 24 threads give it a structural edge in multi-threaded rendering and compilation workloads.

The Intel Arc G3 EXTREME wins nothing in the head-to-head data, but its specification sheet indicates its intended role. The 25 watt TDP, 3 nm process, LPDDR5X memory with 136.5 GB/s bandwidth, and mobile BGA 2540 socket all point to a low-power mobile platform. Its 14 cores without multithreading and 18 MB of shared L3 cache are modest by desktop standards. The closest result, PassMark single-thread at 8.2 percent behind, shows that the Intel's single-core performance is near the AMD's. Its Arc B390 integrated graphics and Gen 5 PCIe with 4 lanes suit a compact mobile system.

The practical split is market segment, not performance. The AMD is a desktop processor with a 120 watt TDP, unlocked multiplier, ECC memory support, and a $599 launch MSRP. The Intel is a mobile processor with a 25 watt TDP, locked multiplier, no ECC support, and no recorded launch MSRP. Buyers selecting a high-performance desktop CPU have a clear choice. Buyers selecting a low-power mobile CPU have only one option in this comparison. The benchmark data does not show the Intel winning any workload, but its power envelope and mobile socket define a usage scenario the AMD cannot serve.
