AMD Ryzen 9 5900XT vs Intel Arc G3 EXTREME Comparison

Benchmark results in the database place the AMD Ryzen 9 5900XT and the Intel Arc G3 EXTREME in different market segments, and the shared test list reflects that split. The 5900XT wins 13 of the shared tests, while the Arc G3 EXTREME wins 4. The AMD part averages 50718 across its benchmark records and sits in the 90th percentile of all CPUs; the Intel part averages 36699 and sits in the 85th percentile. The 5900XT is a desktop AM4 processor with 16 cores and 32 threads, while the Arc G3 EXTREME is a mobile BGA 2540 processor with 14 cores and 14 threads. Their architecture, memory, and graphics differences are as large as the score gap.

Head-to-Head Benchmarks

Every Cinebench result goes to AMD. In Cinebench R23 multi-core, the 5900XT scores 37373 against 14655, a 155% advantage. In R23 single-core, it scores 5276 against 1862, a 183.4% advantage, the largest margin in the entire comparison. R20 multi-core and single-core both show a 43.4% lead (15696 vs 10945 and 2215 vs 1545). R15 multi-core shows a 71.9% lead (3767 vs 2192), and R15 single-core shows a 98.9% lead (531 vs 267).

Passmark mostly follows the same direction. AMD leads integer math by 149.5% (177566 vs 71164), data compression by 94.7% (597862 vs 307094), random string sorting by 67.5% (62537 vs 37331), extended instructions by 63% (39141 vs 24017), data encryption by 58.3% (37814 vs 23881), multithread by 42.9% (43810 vs 30659), and floating point math by 14.3% (99398 vs 86929).

Intel's four wins are all in Passmark. The Passmark physics score is 2515 against 1715, a 31.8% margin. The Passmark single-thread score is 4293 against 3474, a 19.1% margin, and the same result appears under the passmark_singlethread test name. Passmark find prime numbers goes to Intel by 17.3% (248 vs 205). Intel's largest win is 31.8% in Passmark physics; among AMD's wins, only floating point math at 14.3% is smaller.

The average scores also place both parts near specific rivals in the database. The 5900XT's 50718 average is 0.1% below the Intel Core i7-13850HX (50761), 0.5% above the AMD Ryzen AI 9 HX PRO 370 (50448), 0.6% below the Intel Core i9-14900T (51015), and 0.6% above the Intel Core i9-13980HX (50398). The Arc G3 EXTREME's 36699 average is 0.6% below the Intel Core Ultra 5 225 (36938), 0.7% below the AMD Ryzen 5 5600F (36945), 0.9% below the AMD Ryzen 5 5500X3D (37018), and 1.1% below the AMD Ryzen AI 7 PRO 450 (37093).

Where Each One Wins

AMD's win profile is broad: all Cinebench tests, plus Passmark data compression, encryption, extended instructions, integer math, floating point math, multithread, and random string sorting. That makes the 5900XT the stronger part in the database for workloads represented by these tests, especially multi-threaded Cinebench and integer-heavy Passmark work. Its smallest win is still 14.3% in floating point math, and most of its wins are far larger.

Intel's win profile is narrow but real. The Arc G3 EXTREME wins Passmark single-thread by 19.1%, Passmark physics by 31.8%, and Passmark find prime numbers by 17.3%. These are the only recorded tests where the Intel part outperforms the AMD part. For single-thread Passmark work, physics workloads, and prime-number searches, the data favors Intel.

Architecture Differences

Under the surface, these are very different designs. The 5900XT uses AMD's Zen 3 architecture, codenamed Vermeer, built on TSMC's 7 nm process. It contains 8,300 million transistors across two 74 mm² dies. The Arc G3 EXTREME uses Intel's Panther Lake design, built on Intel's 3 nm process; its transistor count and die size are not recorded in the database.

Core and thread counts differ sharply: 16 cores and 32 threads versus 14 cores and 14 threads. Cache is organized differently as well. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 64 MB of L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. Intel's per-core L1 and L2 are larger, but AMD's L3 is larger overall.

Memory and platform support also diverge. AMD runs DDR4 on a dual-channel bus with 51.2 GB/s bandwidth and ECC support. Intel runs LPDDR5X on a dual-channel bus with 136.5 GB/s bandwidth and no ECC support. AMD uses PCIe Gen 4 with 20 CPU lanes; Intel uses PCIe Gen 5 with 4 CPU lanes. AMD has no integrated graphics; Intel includes Arc B390 graphics. AMD uses Socket AM4 with an unlocked multiplier; Intel uses BGA 2540 with a locked multiplier.

Power and clock behavior reflect their segments. The 5900XT has a 105 W TDP, a 3.30 base clock, and a 4.80 boost clock. The Arc G3 EXTREME has a 25 W TDP, a 1.90 base clock, and a 4.70 boost clock. Despite the lower base clock, the Intel part wins the Passmark single-thread test, which shows that clock speed alone does not explain the benchmark results.

The Verdict

Across the recorded data, the AMD Ryzen 9 5900XT is the higher-performing processor in most shared tests. It wins 13 of the shared tests, including every Cinebench test, and its average benchmark score of 50718 places it in the 90th percentile, above the Arc G3 EXTREME's 85th percentile. The largest margins are overwhelmingly AMD's: 183.4% in Cinebench R23 single-core, 155% in Cinebench R23 multi-core, and 149.5% in Passmark integer math.

The Intel Arc G3 EXTREME is not without advantages. It wins Passmark physics by 31.8%, Passmark single-thread by 19.1%, and Passmark find prime numbers by 17.3%. It also uses a 3 nm process, supports LPDDR5X at 136.5 GB/s, includes integrated Arc B390 graphics, and fits a 25 W mobile platform. Those traits make it the appropriate part for the mobile segment represented by its BGA 2540 socket.

For a desktop AM4 processor with 16 cores, 32 threads, 64 MB of L3, ECC memory support, and an unlocked multiplier, the database points to the AMD Ryzen 9 5900XT. For a low-power mobile processor with integrated graphics and a Passmark single-thread/physics edge, the database points to the Intel Arc G3 EXTREME.
