AMD Ryzen AI 7 345 vs Intel Arc G3 EXTREME Comparison

The Verdict

The benchmark data presents a clear hierarchy between these two mobile processors. The Intel Arc G3 EXTREME wins 14 of the 15 recorded head-to-head comparisons, while the AMD Ryzen AI 7 345 takes a single victory. The Intel part records an average benchmark score of 36699 against the AMD part's 29461, a gap of roughly 24.5 percent. The Intel processor also sits in the 85th percentile of all CPUs in the database, while the AMD processor sits in the 81st percentile. For workloads that stress multiple cores, sustained throughput, or math-heavy operations, the data points squarely to the Intel Arc G3 EXTREME. The AMD Ryzen AI 7 345 retains a narrow edge in one specific legacy single-core test, but that advantage does not carry over to other single-threaded measurements. The database shows that the Intel part is the stronger overall choice for users who prioritize raw compute performance across a broad range of tasks. The AMD part remains competitive only in a very narrow slice of the benchmark suite, and even there the margin is small.

Architecture Differences

The two processors come from different foundries and use different process nodes. The AMD Ryzen AI 7 345 is built on a 4 nm process at TSMC, while the Intel Arc G3 EXTREME uses a 3 nm process at Intel. The AMD part belongs to the Krackan Point codename family within the Ryzen AI 300 generation, which uses a hybrid of Zen 5 and Zen 5c cores. The Intel part belongs to the Panther Lake codename family within the Arc G3 generation. Core counts differ substantially: the AMD processor has 6 cores and 12 threads, while the Intel processor has 14 cores and 14 threads. The Intel part does not use simultaneous multithreading, so its thread count equals its core count, whereas the AMD part doubles its threads over its cores.

Cache configurations also diverge. The AMD processor lists 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3 cache. The Intel processor lists 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The Intel part therefore carries significantly more on-die cache at every level, which helps explain its advantage in repeated or cache-sensitive workloads. Memory support differs as well: the AMD part supports both DDR5 and LPDDR5X memory over a dual-channel bus with a recorded bandwidth of 89.6 GB/s. The Intel part supports only LPDDR5X over a dual-channel bus but reaches 136.5 GB/s of memory bandwidth. That bandwidth advantage feeds directly into many of the benchmark results. The PCIe interface also differs, with the AMD part using Gen 4 with 14 CPU lanes and the Intel part using Gen 5 with 4 CPU lanes. Integrated graphics differ too: the AMD part uses a Radeon 840M, while the Intel part uses an Arc B390. Both parts are mobile-market segments, are currently active in production, and are not multiplier-unlocked. The AMD part has a base clock of 2.00 GHz and a boost clock of 4.60 GHz, while the Intel part has a base clock of 1.90 GHz and a boost clock of 4.70 GHz. The Intel part has a higher boost ceiling but a slightly lower base clock. The AMD part carries a TDP of 28, while the Intel part carries a TDP of 25.

Where Each One Wins

The AMD Ryzen AI 7 345 wins exactly one head-to-head benchmark: Cinebench R15 single-core, with a score of 271 against the Intel part's 267, a delta of 1.5 percent in the AMD part's favor. That is a legacy test, and the margin is modest. In every other recorded measurement, the Intel Arc G3 EXTREME takes the win. The Intel part is particularly dominant in multi-threaded and math-heavy workloads. In PassMark floating-point math, the Intel part scores 86929 against the AMD part's 42621, a delta of 51 percent. In PassMark data encryption, the Intel part scores 23881 against 11814, a delta of 50.5 percent. In PassMark physics, the Intel part scores 2515 against 1089, a delta of 56.7 percent. In PassMark find prime numbers, the Intel part scores 248 against 62, a delta of 75 percent. Those are the largest gaps in the entire comparison.

The Intel part also leads in Cinebench R23 multi-core with a score of 14655 against 11461, a 21.8 percent advantage, and in Cinebench R15 multi-core with a score of 2192 against 1712, a 21.9 percent advantage. In PassMark multithread, the Intel part scores 30659 against 19927, a 35 percent gap. In PassMark integer math, the Intel part leads by 10.8 percent, scoring 71164 against 63475. In PassMark random string sorting, the Intel part leads by 31.9 percent, scoring 37331 against 25435. In PassMark extended instructions, the Intel part leads by 29.2 percent, scoring 24017 against 17003. In PassMark data compression, the Intel part leads by 22.7 percent, scoring 307094 against 237484. Even in single-threaded PassMark tests, the Intel part leads by 9.7 percent, scoring 4293 against 3875. In Cinebench R23 single-core, the Intel part leads by 2.4 percent, scoring 1862 against 1818.

The pattern is consistent: the Intel part wins on both core-count-heavy workloads and single-threaded modern tests. The AMD part's sole win is isolated to a single older Cinebench iteration.

Head-to-Head Benchmarks

The largest margin in the entire comparison appears in PassMark find prime numbers. The Intel Arc G3 EXTREME scores 248, while the AMD Ryzen AI 7 345 scores 62. That is a delta of 75 percent, meaning the Intel part completes the operation at four times the rate of the AMD part. This test is highly sensitive to integer throughput and cache behavior, and the Intel part's larger cache and higher core count align with that result.

The second-largest gap is in PassMark physics, where the Intel part scores 2515 against the AMD part's 1089, a delta of 56.7 percent. Physics simulation typically scales with multi-core throughput and memory bandwidth, both of which favor the Intel part. PassMark floating-point math shows a similar story: the Intel part scores 86929 against 42621, a delta of 51 percent. Floating-point math exercises the execution pipelines heavily, and the Intel part's 14 cores provide a substantial advantage over the AMD part's 6 cores.

PassMark data encryption shows a delta of 50.5 percent, with the Intel part scoring 23881 against 11814. Encryption workloads often rely on dedicated instruction sets and memory bandwidth; the Intel part's extended instructions score of 24017 against 17003, a 29.2 percent delta, supports that interpretation. PassMark multithread shows a 35 percent gap, with the Intel part scoring 30659 against 19927. PassMark random string sorting shows a 31.9 percent delta, with the Intel part scoring 37331 against 25435. PassMark extended instructions shows a 29.2 percent delta as noted. PassMark data compression shows a 22.7 percent delta, with the Intel part scoring 307094 against 237484.

Cinebench R23 multi-core shows the Intel part at 14655 against 11461, a 21.8 percent delta. Cinebench R15 multi-core shows the Intel part at 2192 against 1712, a 21.9 percent delta. Both multi-core Cinebench results are closely aligned, indicating a consistent multi-threaded advantage. PassMark integer math shows a smaller but still clear gap: the Intel part scores 71164 against 63475, a 10.8 percent delta. PassMark single-thread shows the Intel part at 4293 against 3875, a 9.7 percent delta. Cinebench R23 single-core shows the Intel part at 1862 against 1818, a 2.4 percent delta. The only AMD win is Cinebench R15 single-core at 271 against 267, a 1.5 percent delta.

The data shows that the Intel part's advantage grows with workload complexity and parallelism. In the least demanding single-core legacy test, the AMD part edges ahead. In every other scenario, including modern single-threaded tests, the Intel part leads. The Cinebench R23 single-core result, which is a more recent test than R15, shows the Intel part ahead by 2.4 percent. The PassMark single-thread result, which is also a contemporary measurement, shows the Intel part ahead by 9.7 percent. That suggests the AMD part's R15 win is an artifact of that specific test's characteristics rather than a general single-core superiority.
