Architecture Differences

The two processors come from different Intel generations and are built for different market segments. The Intel Arc G3 EXTREME is a mobile processor from the Panther Lake generation, manufactured on a 3 nm process node and built by Intel. The Intel Core i9-14900 is a desktop processor from the Raptor Lake Refresh generation, using the Raptor Lake-R architecture and manufactured on a 10 nm process node.

The core counts differ significantly. The Arc G3 EXTREME has 14 cores and 14 threads, indicating no hyperthreading support. The i9-14900 has 24 cores and 32 threads, which implies a hybrid core layout with performance and efficiency cores. This is a substantial difference in parallel processing capability.

Cache hierarchies also differ. The Arc G3 EXTREME has 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with 18 MB of shared L3 cache. The i9-14900 has 80 KB of L1 cache per core and 2 MB of L2 cache per core, but a much larger 36 MB of shared L3 cache. The larger shared cache on the i9-14900 benefits workloads with large working sets.

The memory support differs as well. The Arc G3 EXTREME supports LPDDR5X memory with a dual-channel bus and a recorded memory bandwidth of 136.5 GB/s. The i9-14900 supports both DDR4 and DDR5 memory on a dual-channel bus, but no memory bandwidth figure is recorded in the database. The i9-14900 also supports ECC memory, while the Arc G3 EXTREME does not.

PCIe capabilities are different. The Arc G3 EXTREME provides Gen 5 with 4 lanes (CPU only). The i9-14900 provides Gen 5 with 16 lanes (CPU only), giving it significantly more PCIe bandwidth for expansion.

Integrated graphics differ. The Arc G3 EXTREME uses Arc B390 graphics, while the i9-14900 uses UHD Graphics 770. The sockets are entirely different as well: the Arc G3 EXTREME uses Intel BGA 2540, while the i9-14900 uses Intel Socket 1700.

The power envelope is notably different. The Arc G3 EXTREME has a TDP of 25, while the i9-14900 has a TDP of 65. The die size for the i9-14900 is recorded at 257 mm², while no die size is recorded for the Arc G3 EXTREME.

Where Each One Wins

The Intel Core i9-14900 dominates the vast majority of workloads. Its wins span Cinebench R15, R20, and R23 in both single-core and multi-core tests. It also wins in PassMark data compression, data encryption, extended instructions, floating point math, integer math, multithread, random string sorting, and single-thread tests.

The i9-14900 is particularly strong in integer-heavy workloads. The PassMark integer math score shows a 59.3% advantage over the Arc G3 EXTREME. Data compression is another area of strength, with a 44.2% lead. The multi-core Cinebench results show a massive advantage, with the R15 multi-core score 54.3% higher and the R23 multi-core score 52.8% higher.

The Intel Arc G3 EXTREME wins only two benchmarks. The first is PassMark find prime numbers, where it scores 248 versus 188, a 31.9% advantage. The second is PassMark physics, where it scores 2515 versus 2486, a 1.2% edge. These wins indicate that the Arc G3 EXTREME has some specific strengths in certain computational patterns, but they are narrow categories.

The Arc G3 EXTREME also holds its own in single-thread performance. The PassMark single-thread score is 4293 versus 4323, a difference of only 0.7%. This suggests that the newer 3 nm process node helps close the gap in lightly threaded workloads, even though the i9-14900 has a higher boost clock.

For general productivity, the i9-14900 is the clear choice. For mobile deployment with lower power consumption, the Arc G3 EXTREME becomes relevant, but its benchmark wins remain limited to specific niche workloads.

The PassMark extended instructions test shows a 21.6% lead for the i9-14900, with scores of 30624 versus 24017. The single-core Cinebench results are closer but still favor the i9-14900. The R23 single-core test shows 2212 versus 1862, a 15.8% difference. The R20 single-core test shows 2245 versus 1545, a 31.2% difference. The R15 single-core test shows 315 versus 267, a 15.2% difference.

The PassMark single-thread test is nearly identical: 4323 versus 4293, a 0.7% difference. This is the closest benchmark in the entire set.

The Arc G3 EXTREME wins the PassMark find prime numbers test with 248 versus 188, a 31.9% advantage. It also wins the PassMark physics test with 2515 versus 2486, a 1.2% edge. These are the only two benchmarks where the Arc G3 EXTREME comes out ahead.

The Verdict

The recorded data clearly favors the Intel Core i9-14900 for almost all compute workloads. It wins 15 of 17 head-to-head benchmarks and holds a higher average benchmark score of 58115 versus 36699. Its percentile ranking of 92 versus 85 reflects this overall advantage.

The i9-14900 is the appropriate choice for multi-threaded desktop workloads. The 24 cores and 32 threads provide substantial parallel processing capability, and the 36 MB of shared L3 cache supports large working sets. The 5.80 GHz boost clock also helps in single-threaded tasks, even though the single-thread gap is small.

The Arc G3 EXTREME is the appropriate choice for mobile deployment. It has a TDP of 25 versus 65, making it far more power-efficient. It also uses a more advanced 3 nm process node, which likely contributes to its competitive single-thread performance. The PassMark single-thread gap is only 0.7%, which is within a narrow margin.

The Arc G3 EXTREME also wins the find prime numbers test by a substantial margin of 31.9%, indicating that specific algorithmic workloads may favor its architecture. The physics test win, though marginal at 1.2%, adds to its niche advantages.

The choice between these two processors depends on the deployment context. For desktop systems requiring maximum throughput across a wide range of benchmarks, the i9-14900 delivers consistently higher scores. For mobile systems where power consumption matters and workloads align with its strengths, the Arc G3 EXTREME offers a viable alternative. The data does not support a broader recommendation for the Arc G3 EXTREME beyond its mobile segment and the specific benchmark wins it records.
