AMD Ryzen AI 7 450 vs Intel Arc G3 EXTREME Comparison

AMD Ryzen AI 7 450 and Intel Arc G3 EXTREME target the same mobile segment but deliver opposite performance profiles. The AMD part wins the aggregate benchmark average with 39485 points against 36699 for the Intel part, placing the Ryzen in the 87th percentile of all CPUs versus the 85th percentile for the Arc G3 EXTREME. The head-to-head record is lopsided in raw count, with Intel taking 10 of 15 comparisons, but the AMD wins are concentrated in the most demanding multi-threaded workloads.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen AI 7 450 comes in Cinebench R23 multi-core, where it scores 18316 against 14655 for the Intel Arc G3 EXTREME, a 25% advantage. The older Cinebench R15 multi-core test shows a similar story: 2713 versus 2192, a 23.8% lead. In PassMark integer math, AMD leads 88531 to 71164, a 24.4% margin, and data compression goes to AMD at 315906 versus 307094, a narrower 2.9% edge. Cinebench R23 single-core also favors AMD, 2038 to 1862, a 9.5% difference.

The Intel Arc G3 EXTREME counters with decisive wins in several specialized workloads. PassMark floating point math is the biggest gap: 86929 versus 54447, a 37.4% lead for Intel. PassMark physics shows 2515 against 1578, a 37.3% margin, and prime number finding delivers 248 versus 89, a massive 64.1% delta. Data encryption goes to Intel at 23881 versus 16247, a 32% lead, while extended instructions favor Intel by 6.7% (24017 versus 22400). PassMark multi-thread overall goes to Intel at 30659 versus 26350, a 14.1% gap, and the single-thread PassMark score favors Intel at 4293 versus 3901, a 9.1% margin. Random string sorting is a smaller Intel win, 37331 versus 35648, a 4.5% edge. Cinebench R15 single-core is the only Cinebench test Intel wins, 267 versus 215, a 19.5% lead.

What stands out is the split between rendering and math. The AMD chip leads in Cinebench multi-core and integer math, while the Intel part dominates floating point, physics, and encryption. The data records 5 wins for AMD and 10 for Intel, but the AMD aggregate average remains higher because its Cinebench multi-core margin is large enough to offset multiple narrow Intel wins.

Architecture Differences

The AMD Ryzen AI 7 450 uses the Zen 5 architecture on a 4 nm TSMC process, with the codename Gorgon Point and the generation label Ryzen AI 400 (Zen 5 / Zen 5c). It packs 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel Arc G3 EXTREME uses a 3 nm Intel process with the Panther Lake codename and the Arc G3 generation label. It has 14 cores and 14 threads, base clock 1.90 GHz and boost clock 4.70 GHz. Intel does not show an architecture field in the database, so the core design details are limited to what the cache and clock data imply.

Cache layouts differ substantially. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The larger per-core L1 and L2 on the Intel side likely feed its strong single-thread PassMark score, while the larger shared L3 could help in workloads that reuse data across cores.

Memory support also diverges. The AMD chip supports DDR5 and LPDDR5X in dual-channel mode, with 89.6 GB/s of memory bandwidth and ECC support. The Intel chip supports only LPDDR5X, also dual-channel, but with 136.5 GB/s of bandwidth and no ECC. That bandwidth advantage is significant: the Intel part has roughly 52% more memory bandwidth, which aligns with its wins in floating point and physics workloads that often scale with data throughput.

PCIe connectivity differs in both generation and lane count. AMD uses PCIe Gen 4 with 16 CPU lanes, while Intel uses PCIe Gen 5 with 4 CPU lanes. The integrated graphics are Radeon 860M on the AMD side and Arc B390 on the Intel side. Both are mobile parts with active production status. The AMD part is rated at 28 W TDP, the Intel part at 25 W. Neither has an unlocked multiplier. AMD uses Socket FP8, Intel uses BGA 2540.

Where Each One Wins

The AMD Ryzen AI 7 450 is the stronger choice for multi-threaded rendering and general integer-heavy computation. Cinebench R23 multi-core shows a 25% advantage, and Cinebench R15 multi-core shows 23.8%. Integer math is 24.4% ahead. Data compression also favors AMD, though by a smaller margin. For users running CPU rendering, code compilation, or any workload that relies on sustained multi-core throughput, the AMD part is the clear leader in this comparison.

The Intel Arc G3 EXTREME wins in floating point, physics simulation, and encryption. The 37.4% floating point lead and 37.3% physics lead are substantial. Prime number finding is the most extreme Intel advantage at 64.1%, suggesting strong single-core integer efficiency in a specific instruction pattern. Data encryption at 32% ahead indicates the Intel part handles AES and related workloads better. PassMark multi-thread favors Intel at 30659 versus 26350, which appears contradictory to the Cinebench results but reflects the PassMark suite weighting toward the kinds of parallel workloads where Intel performs well. Single-thread PassMark also favors Intel at 4293 versus 3901.

The split is clear: AMD for Cinebench-style rendering and integer work, Intel for floating point, physics, encryption, and PassMark's overall multi-thread metric. The data does not support a universal winner. Each part leads in workloads that map to its architectural strengths.

The Verdict

The data supports a workload-based decision. The AMD Ryzen AI 7 450 should be the pick for multi-threaded rendering workloads, where it leads Cinebench R23 multi-core by 25% and Cinebench R15 multi-core by 23.8%. It also wins integer math by 24.4%, making it the better choice for general productivity and code compilation. The higher average benchmark score and 87th percentile ranking reinforce its position as the stronger overall processor in this pairing.

The Intel Arc G3 EXTREME is the pick for floating point heavy tasks, physics simulation, and encryption. The 37.4% floating point lead and 37.3% physics lead are decisive. The 32% encryption advantage and 64.1% prime number win show where Intel's architecture excels. The higher memory bandwidth of 136.5 GB/s versus 89.6 GB/s supports these wins. The lower 25 W TDP also makes it an efficient option for those specific workloads.

Neither part dominates every category. The AMD part has 5 head-to-head wins, the Intel part has 10. The AMD aggregate score is higher because its Cinebench multi-core margin is large. Buyers should match the CPU to the dominant workload. Rendering and integer work point to AMD. Floating point, physics, and encryption point to Intel.
