AMD Ryzen AI 7 PRO 450 vs Intel Arc G3 EXTREME Comparison

The AMD Ryzen AI 7 PRO 450 and Intel Arc G3 EXTREME are both active mobile processors targeting the same high-performance segment, and their aggregate benchmark scores are nearly identical. However, the data reveals two very different personalities. The AMD chip wins 4 of 15 head-to-head tests, while the Intel part claims 11, yet the overall average benchmark score for the AMD is 37093 compared to 36699 for the Intel, a gap of less than 1.1%. This is a classic split: one processor is a multi-threaded workhorse, while the other is a specialized accelerator for specific workloads.

Where Each One Wins

The AMD Ryzen AI 7 PRO 450 is the clear choice for traditional CPU-heavy productivity and rendering tasks. Its victories in Cinebench R23 multi-core (16054 vs 14655) and Cinebench R15 multi-core (2457 vs 2192) show a consistent 9.5% to 12.1% advantage in sustained all-core workloads. It also dominates integer math, scoring 86227 against 71164, a 21.2% lead, which translates to better performance in general-purpose computing, code compilation, and spreadsheet-style number crunching. For users whose daily driver is a video encoder, a 3D renderer, or a developer workstation, the AMD chip delivers more throughput where it counts.

The Intel Arc G3 EXTREME, in contrast, is a specialist in cryptography, physics, and floating-point operations. Its most lopsided victory is in the PassMark find prime numbers test, scoring 248 versus just 84, a staggering 66.1% advantage. This pattern repeats in floating-point math (86929 vs 52971, a 39.1% lead) and data encryption (23881 vs 14925, a 37.5% lead). The Intel part also wins the PassMark multi-thread test with 30659 against 24779, a 19.2% margin, and the physics test with 2515 versus 1337, a 46.8% lead. If a workload is heavily reliant on cryptographic hashing, scientific simulation, or physics calculations, the Intel chip is the superior engine.

The split is not absolute, though. The Intel part also wins the single-threaded Cinebench R15 test (267 vs 220, a 17.6% lead), but loses the more modern Cinebench R23 single-core test (2010 vs 1862, a 7.9% deficit). This suggests that AMD’s newer architecture has better per-core efficiency at higher clocks, while Intel’s advantage lies in raw peak frequency and specialized instruction throughput. For a user who does a bit of everything, the choice depends on whether the workload leans toward integer-heavy general tasks (AMD) or floating-point and cryptographic tasks (Intel).

Head-to-Head Benchmarks

The largest victory for the AMD Ryzen AI 7 PRO 450 comes in the PassMark integer math test, where it scores 86227 against Intel’s 71164. That is a 21.2% lead, the most decisive win for the AMD part in any benchmark. In Cinebench R15 multi-core, the AMD scores 2457 versus 2192, a 12.1% advantage, and in Cinebench R23 multi-core, it scores 16054 versus 14655, a 9.5% margin. The AMD also wins Cinebench R23 single-core, posting 2010 against Intel’s 1862, a 7.9% improvement.

The Intel Arc G3 EXTREME counters with several larger margins. Its biggest win is in PassMark find prime numbers, where it scores 248 versus 84, a 66.1% blowout. It also wins PassMark floating-point math with 86929 versus 52971, a 39.1% lead, and PassMark data encryption with 23881 versus 14925, a 37.5% advantage. The Intel part takes PassMark physics with 2515 versus 1337, a 46.8% margin, and PassMark multi-thread with 30659 versus 24779, a 19.2% lead. In the single-threaded PassMark test, Intel wins 4293 versus 3955, a 7.9% edge, matching the AMD’s single-core win in Cinebench R23.

The pattern in these results is clear: AMD’s wins are concentrated in integer-heavy, all-core rendering tasks, while Intel’s wins dominate in floating-point, cryptographic, and physics-based simulations. The data compression test is close, with Intel winning 307094 versus 294298, a modest 4.2% margin, and the random string sorting test also goes to Intel at 37331 versus 32344, a 13.4% lead. The extended instructions test favors Intel at 24017 versus 20778, a 13.5% difference. Only four tests go to AMD, but two of those are the most widely cited Cinebench multi-core scores, suggesting that AMD’s real-world rendering performance is more consistent.

Specification Differences

The two processors differ in nearly every fundamental specification. The AMD Ryzen AI 7 PRO 450 has 8 cores and 16 threads, while the Intel Arc G3 EXTREME has 14 cores and 14 threads. The AMD’s base clock is 2.00 GHz and boosts to 5.10 GHz, whereas the Intel starts at 1.90 GHz and boosts to 4.70 GHz. The thermal design power differs slightly, with the AMD rated at 28 watts and the Intel at 25 watts.

The cache configurations are distinct. The AMD has 80 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of L3 cache. The Intel has 192 KB of L1 per core, 2.5 MB of L2 per core, and a much larger 18 MB of shared L3 cache. Memory support also diverges: the AMD supports both DDR5 and LPDDR5X, while the Intel supports only LPDDR5X. The memory bandwidth is drastically higher on the Intel part, at 136.5 GB/s versus 89.6 GB/s for the AMD. The AMD supports ECC memory, while the Intel does not.

The PCIe configurations are also different. The AMD offers Gen 4 with 16 lanes (CPU only), while the Intel provides Gen 5 with 4 lanes (CPU only). The integrated graphics differ as well, with the AMD featuring a Radeon 860M and the Intel featuring an Arc B390. The sockets are incompatible: the AMD uses AMD Socket FP8, while the Intel uses Intel BGA 2540. The AMD has a die size of 195 mm², while the Intel’s die size is not listed. The AMD’s part number is 100-000001865, and the Intel’s is SA4R3.

Architecture Differences

The architectural divide is stark. The AMD Ryzen AI 7 PRO 450 is built on a 4 nm process from TSMC, while the Intel Arc G3 EXTREME uses a 3 nm process from Intel’s own foundry. The AMD’s architecture is Zen 5, with the codename Gorgon Point, and it belongs to the Ryzen AI PRO 400 generation, which uses a mix of Zen 5 and Zen 5c cores. The Intel part is based on the Panther Lake codename, belonging to the Arc G3 generation, though its specific architecture is not listed in the data.

The cache hierarchy reflects different design philosophies. AMD’s per-core L1 and L2 caches are smaller (80 KB and 1 MB per core), but it relies on a more balanced design. Intel’s per-core caches are larger (192 KB L1 and 2.5 MB L2), and it has a much larger shared L3 cache of 18 MB versus AMD’s 8 MB. This larger cache, combined with higher memory bandwidth (136.5 GB/s vs 89.6 GB/s), likely contributes to Intel’s dominance in floating-point and encryption tasks, which benefit from larger data buffers.

The process node difference is significant: Intel’s 3 nm process is one step ahead of AMD’s 4 nm node. This gives Intel a transistor density advantage, though the AMD chip compensates with a higher boost clock of 5.10 GHz versus 4.70 GHz and support for simultaneous multi-threading (16 threads vs 14). The AMD also has a higher TDP of 28 watts versus 25 watts, allowing for more sustained power draw. The Intel part supports PCIe Gen 5, while the AMD is limited to Gen 4, but the AMD has 16 lanes versus Intel’s 4 lanes, making the AMD better suited for multiple high-bandwidth devices. The integrated graphics are also generationally different, with AMD’s Radeon 860M versus Intel’s Arc B390, though no benchmark data is provided for those iGPUs.
