AMD Ryzen AI 7 445 vs Intel Arc G3 EXTREME Comparison

Where Each One Wins

The recorded benchmark data is unambiguous: the Intel Arc G3 EXTREME wins every single head-to-head test in the database. Out of 15 direct comparisons, Intel takes 15, while the AMD Ryzen AI 7 445 takes zero. That is a clean sweep, but the margins vary widely depending on the workload type, which matters for real-world task selection.

The AMD Ryzen AI 7 445 is not without merit in absolute terms. It posts a solid Cinebench R23 multi-core score of 10,590 and a single-core score of 1,806, which places it in the 79th percentile of all CPUs in the database. However, the Intel part sits in the 85th percentile, and its average benchmark score of 36,699 versus AMD's 26,936 reflects a roughly 36% overall advantage in the aggregate data.

The Intel Arc G3 EXTREME's largest wins come in heavily parallel or compute-intensive workloads. Its PassMark physics score of 2,515 is 61.2% ahead of AMD's 976, and its floating-point math score of 86,929 beats AMD's 39,362 by 54.7%. These are workloads where the Intel part's higher core count and larger cache pool clearly pay off.

The AMD chip's closest relative performance appears in single-threaded Cinebench tests, where the gap narrows dramatically. In Cinebench R15 single-core, Intel leads by just 4.9% (267 versus 254), and in R23 single-core the margin is only 3% (1,862 versus 1,806). This suggests that for lightly threaded tasks, the two parts are nearly equivalent, with Intel holding only a slim edge despite its architectural advantages.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 445 uses a 6-core, 12-thread configuration built on the Zen 5 architecture, fabricated on TSMC's 4 nm process. Its codename is Gorgon Point, and it belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. The Intel Arc G3 EXTREME, by contrast, packs 14 cores and 14 threads on Intel's 3 nm process, using the Panther Lake architecture from the Arc G3 generation. The core count difference is stark: Intel has 8 more physical cores, but AMD's simultaneous multithreading gives it 12 threads versus Intel's 14, so the thread gap is only 2.

Cache layouts diverge significantly. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and just 4 MB of shared L3 cache. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and a much larger 18 MB of shared L3. That 14 MB difference in L3 is substantial and helps explain Intel's dominance in cache-sensitive workloads like data compression and random string sorting.

Memory support also differs. Both are dual-channel, but AMD supports DDR5 and LPDDR5X with a memory bandwidth of 89.6 GB/s, while Intel supports only LPDDR5X but at a higher 136.5 GB/s. That is a 52.8% bandwidth advantage for Intel, which directly feeds its stronger performance in memory-bound tasks. AMD also supports ECC memory, which Intel does not, a feature relevant for specific reliability-focused use cases.

PCIe connectivity is another split. AMD provides Gen 4 with 14 lanes from the CPU, while Intel offers Gen 5 with only 4 lanes. The newer standard on Intel means faster per-lane bandwidth, but far fewer lanes, which could constrain multi-device expansion. Integrated graphics differ as well: AMD uses the Radeon 840M, Intel the Arc B390. Both target mobile, and both are currently active production parts.

Head-to-Head Benchmarks

The biggest single margin in the entire dataset appears in PassMark's find prime numbers test, where Intel scores 248 against AMD's 56, a 77.4% advantage. This test is highly sensitive to integer throughput and memory latency, and Intel's larger cache and higher bandwidth clearly dominate. Similarly, PassMark data encryption shows Intel at 23,881 versus AMD's 10,519, a 56% gap, indicating strong AES and cryptographic instruction throughput on the Intel side.

Cinebench multi-core results reinforce the pattern. In R15 multi-core, Intel scores 2,192 versus AMD's 1,723, a 21.4% lead. In R23 multi-core, the gap widens to 27.7%, with Intel at 14,655 and AMD at 10,590. The scaling suggests Intel's 14 cores handle sustained rendering workloads better than AMD's 6 cores with SMT. PassMark multi-thread tells a similar story: Intel's 30,659 beats AMD's 18,115 by 40.9%.

Floating-point math is another Intel stronghold, with 86,929 versus 39,362, a 54.7% margin. Physics simulation shows a 61.2% gap (2,515 versus 976), and extended instructions land at 34.1% (24,017 versus 15,826). Integer math is closer but still Intel-favored: 71,164 versus 58,332, an 18% difference. Data compression shows a 29.7% gap (307,094 versus 215,812), and random string sorting is 37.1% apart (37,331 versus 23,488).

The narrowest margins are in single-threaded Cinebench tests. R15 single-core gives Intel a 4.9% edge (267 versus 254), and R23 single-core shows just 3% (1,862 versus 1,806). PassMark single-thread, however, shows a larger 16.4% gap (4,293 versus 3,591), suggesting that PassMark's single-thread test stresses aspects of the architecture where Intel's newer process and larger per-core cache matter more than pure IPC improvements.

The Verdict

The data points to a clear hierarchy. The Intel Arc G3 EXTREME is the faster processor in every measured workload, with an average benchmark score of 36,699 versus AMD's 26,936. Its 85th percentile ranking versus AMD's 79th places it firmly above in the overall distribution. The Intel part's nearest rivals include the Intel Core Ultra 5 225 (delta -0.6%), AMD Ryzen 5 5600F (delta -0.7%), and AMD Ryzen 5 5500X3D (delta -0.9%), all of which sit within 1% of its average score. AMD's nearest rivals are the Intel Core i7-1370P (delta 0.1%), AMD Ryzen 5 7545U (delta 0.3%), AMD Ryzen 7 5700G (delta -0.4%), and Intel Core i9-9900K (delta -0.6%), indicating the Ryzen AI 7 445 competes with a lower performance tier.

For buyers prioritizing multi-threaded rendering, physics simulation, encryption, or any compute-heavy mobile workload, the Intel Arc G3 EXTREME is the clear choice based on benchmark results. Its 14 cores, 18 MB of L3 cache, and 136.5 GB/s memory bandwidth deliver decisive advantages in every parallel test. The AMD part still holds relevance for those who need ECC memory support or prefer the AMD Socket FP8 platform, but its performance ceiling is measurably lower across the board.

Single-threaded tasks are the only area where the two approach parity, with Intel leading by 3-5% in Cinebench single-core tests. Even there, Intel does not lose, it simply wins by a smaller margin. The verdict from the database is straightforward: the Intel Arc G3 EXTREME outperforms the AMD Ryzen AI 7 445 in all 15 recorded benchmarks, and the differences range from marginal (3% in R23 single-core) to massive (77.4% in prime number finding).
