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

Head-to-Head Benchmarks

The recorded data shows a split decision across the eleven shared PassMark tests, with the AMD Ryzen AI 7 450G taking six wins and the Intel Arc G3 EXTREME taking five. The margin of victory, however, is not evenly distributed. AMD's wins are often decisive, while Intel's advantage in its strongest tests is also substantial.

The largest single delta in either direction belongs to AMD in integer math. The Ryzen AI 7 450G scores 99,732 against Intel's 71,164, a 40.1% advantage. This is the kind of result that shapes overall compute profiles, as integer operations underpin a wide range of general-purpose workloads. Data compression follows a similar pattern, with AMD scoring 402,831 versus 307,094, a 31.2% lead. Extended instructions also favor AMD, 28,223 to 24,017, a 17.5% gap, and random string sorting goes to AMD by 14.3%, 42,663 to 37,331. Single-thread performance is nearly a dead heat, but AMD still edges ahead by 0.4%, 4,309 to 4,293.

Intel's wins are concentrated in specific math and physics domains. The find prime numbers test shows Intel at 248 against AMD's 87, a 64.9% advantage. Floating point math also goes to Intel, 86,929 to 63,683, a 26.7% lead. The physics test is another Intel victory, 2,515 to 1,440, a 42.7% margin. Data encryption favors Intel, 23,881 to 18,937, a 20.7% gap. The multithread test is the closest of all, with Intel taking it by just 0.8%, 30,659 to 30,422.

The average benchmark score tells a different story. AMD's average is 63,331, placing it in the 93rd percentile of all CPUs. Intel's average is 36,699, putting it in the 85th percentile. That large difference in averages arises because Intel's benchmark list includes multiple Cinebench tests that are not present in AMD's recorded data. The Cinebench R23 multicore score of 14,655 and single-core score of 1,862, along with R20 and R15 results, pull Intel's average down relative to its PassMark performance. The PassMark-only comparison is far closer, with Intel's multithread score actually slightly higher than AMD's.

AMD's nearest rivals in the database include the Intel Core Ultra 7 265HX at 63,173 average (0.2% behind AMD), the Intel Core i7-13790F at 63,080 (0.4% behind), and the AMD Ryzen AI Max PRO 390 at 63,765 (0.7% ahead). Intel's nearest rivals include the Intel Core Ultra 5 225 at 36,938 (0.6% behind Intel), the AMD Ryzen 5 5600F at 36,945 (0.7% behind), and the AMD Ryzen 5 5500X3D at 37,018 (0.9% behind). These clusters confirm that the two processors occupy very different performance tiers in the database, despite the near-tie on the multithread PassMark test.

Architecture Differences

The two processors come from different architectural lineages. AMD's Ryzen AI 7 450G carries the codename Gorgon Point and belongs to the Ryzen AI 400 generation, which uses a mix of Zen 5 and Zen 5c cores. Intel's Arc G3 EXTREME uses the Panther Lake codename and belongs to the Arc G3 generation. AMD's chip is built on a 4 nm process at TSMC, while Intel's is on a 3 nm process at Intel's own foundry. AMD's die size is recorded at 195 mm², while Intel's is not listed in the database.

Core counts differ significantly. Intel has 14 cores and 14 threads, meaning no hyperthreading. AMD has 8 cores and 16 threads, meaning each core supports two threads. AMD's base clock is 2.00 GHz with a boost clock of 5.10 GHz. Intel's base clock is 1.90 GHz with a boost clock of 4.70 GHz. AMD has the higher clock ceiling, while Intel has more physical cores.

Cache hierarchies also differ. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 8 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 larger per-core L1 and L2 caches, plus more than double the L3 capacity, align with its higher core count and its wins in floating point and physics tests.

Memory support diverges as well. AMD supports both DDR5 and LPDDR5X, while Intel supports only LPDDR5X. Both use dual-channel memory buses, but Intel's bandwidth is 136.5 GB/s against AMD's 89.6 GB/s. AMD supports ECC memory; Intel does not. AMD uses PCIe Gen 4 with 12 CPU lanes, while Intel uses PCIe Gen 5 with 4 CPU lanes. The integrated graphics units also differ: AMD uses the Radeon 860M, Intel uses the Arc B390.

AMD's socket is AMD Socket AM5, and its multiplier is unlocked. Intel's socket is Intel BGA 2540, and its multiplier is locked. The market segments differ accordingly: AMD is listed as desktop, Intel as mobile. AMD's part number is 100-000001917; Intel's is SA4R3. AMD's release date is recorded as February 28, 2026, while Intel's is May 27, 2026.

The Verdict

The data presents two processors with complementary strengths. The AMD Ryzen AI 7 450G wins six of the eleven shared benchmarks and holds a 40.1% lead in integer math, a 31.2% lead in data compression, a 17.5% lead in extended instructions, and a 14.3% lead in random string sorting. Its single-thread score of 4,309 is marginally ahead of Intel's 4,293. AMD also has the higher average benchmark score (63,331 versus 36,699) and the higher percentile ranking (93rd versus 85th).

The Intel Arc G3 EXTREME wins the other five shared benchmarks, with particularly strong showings in find prime numbers (64.9% ahead), physics (42.7% ahead), and floating point math (26.7% ahead). It also wins data encryption by 20.7% and edges out the multithread test by 0.8%. Intel's higher core count, larger cache hierarchy, and higher memory bandwidth support these results.

For users whose workloads emphasize integer-heavy tasks, compression, sorting, and single-thread responsiveness, the AMD Ryzen AI 7 450G is the stronger choice based on the recorded scores. For workloads that stress floating point calculations, encryption, physics simulation, or prime number computation, the Intel Arc G3 EXTREME delivers clearly superior numbers. The near-tie in multithread performance means that neither chip dominates general parallel throughput. The decision rests on the specific mix of operations in the target workload.

Where Each One Wins

The AMD Ryzen AI 7 450G wins in integer math, data compression, extended instructions, random string sorting, and single-thread performance. These are the operations that benefit from its higher boost clock of 5.10 GHz, its 16 threads, and its Zen 5-based architecture. The 40.1% lead in integer math and 31.2% lead in data compression suggest that general office workloads, database operations, and compression-heavy tasks will favor AMD. The 0.4% single-thread advantage, while small, points to AMD holding a slight edge in lightly threaded applications.

The Intel Arc G3 EXTREME wins in find prime numbers, floating point math, physics, data encryption, and the multithread PassMark test. Its 64.9% lead in prime number computation and 42.7% lead in physics indicate strong raw computational throughput in specific math-heavy tasks. The 26.7% floating point advantage and 20.7% encryption lead suggest that scientific computing, physics simulation, and cryptographic workloads will favor Intel. The multithread win, although only 0.8%, is notable given that Intel achieves it with 14 threads against AMD's 16.

The memory bandwidth difference also points to Intel in bandwidth-sensitive scenarios. Intel's 136.5 GB/s versus AMD's 89.6 GB/s is a 52.3% advantage in the recorded specification. Intel's larger L3 cache of 18 MB shared, compared to AMD's 8 MB, further supports workloads that repeatedly access a working set larger than AMD's cache can hold. AMD's ECC support and desktop socket give it an edge in reliability-focused desktop builds, while Intel's 25 TDP and mobile socket suit power-constrained portable systems.
