Intel Arc G3 EXTREME vs Intel Core i9-14900T Comparison

The Intel Arc G3 EXTREME and Intel Core i9-14900T represent two very different design philosophies from the same manufacturer. The data shows a clear split: the Core i9-14900T dominates in raw multi-threaded throughput and overall average scores, while the Arc G3 EXTREME counters with notable victories in specific single-threaded and specialized workloads. The Core i9-14900T holds a higher percentile ranking at 90 versus 85 for the Arc G3 EXTREME, with an average benchmark score of 51015 against 36699 for the mobile chip. This 14316-point gap in average score is the first indicator of the performance hierarchy, but the individual test results reveal a more nuanced story than a simple landslide.

Head-to-Head Benchmarks

The Core i9-14900T wins 12 of the 17 recorded head-to-head comparisons, and its victories are often substantial. The largest margin comes in the Cinebench R23 multi-core test, where the Core i9-14900T scores 30803 against 14655 for the Arc G3 EXTREME, a delta of -52.4%. This result more than doubles the Arc G3 EXTREME's output and reflects the Core i9's 24 cores and 32 threads versus the Arc G3 EXTREME's 14 cores and 14 threads. The Cinebench R15 multi-core test shows a similar pattern, with the Core i9-14900T scoring 3104 versus 2192, a -29.4% delta. The Cinebench R20 multi-core result narrows the gap to -15.4%, with scores of 12937 and 10945 respectively, but the Core i9-14900T still holds a commanding lead.

Single-core Cinebench results also favor the Core i9-14900T decisively. In Cinebench R23 single-core, the Core i9-14900T scores 4348 against 1862, a -57.2% delta, its second-largest win overall. Cinebench R15 single-core shows 438 versus 267, a -39% delta, and Cinebench R20 single-core records 1826 versus 1545, a -15.4% delta. These results indicate that the Core i9-14900T's 5.50 GHz boost clock outperforms the Arc G3 EXTREME's 4.70 GHz boost in rendering workloads, despite the Arc chip's newer 3 nm process node.

PassMark integer math heavily favors the Core i9-14900T, which scores 138149 versus 71164, a -48.5% delta. Data compression also goes to the Core i9-14900T with 436066 versus 307094, a -29.6% delta. Random string sorting records 49484 for the Core i9-14900T against 37331, a -24.6% delta. Multi-threaded PassMark scores show 36239 for the Core i9-14900T versus 30659, a -15.4% delta, and floating point math delivers 92699 versus 86929, a -6.2% delta. Data encryption is closer, with 27062 versus 23881, an -11.8% delta.

The Arc G3 EXTREME wins the remaining five comparisons, and its victories are concentrated in specific areas. The most dramatic is the PassMark find prime numbers test, where the Arc G3 EXTREME scores 248 against 164, a 51.2% delta in its favor. This is a specialized integer workload that clearly responds to the Panther Lake architecture. The PassMark single-thread test shows the Arc G3 EXTREME at 4293 versus 4016, a 6.9% delta, with the identical result appearing in the PassMark singlethread duplicate. PassMark physics also favors the Arc G3 EXTREME, scoring 2515 versus 2245, a 12% delta. The extended instructions test gives the Arc G3 EXTREME 24017 versus 23660, a narrow 1.5% delta.

The Verdict

The benchmark data indicates that the Core i9-14900T is the superior processor for the vast majority of workloads. Its Cinebench R23 multi-core score of 30803 is more than double the Arc G3 EXTREME's 14655, and its integer math score of 138149 is nearly double the Arc chip's 71164. The Core i9-14900T also holds the higher percentile ranking at 90 versus 85, and its average benchmark score of 51015 places it in a performance tier that the Arc G3 EXTREME's 36699 cannot reach. The Core i9-14900T's nearest rivals include the Intel Core Ultra 9 285T with a delta of -0.6% and the AMD Ryzen 9 5900XT with a delta of 0.6%, while the Arc G3 EXTREME's nearest rivals are all within 1.1% of its average score, indicating a much tighter competitive field around the mobile chip.

The Core i9-14900T is the clear choice for anyone prioritizing rendering, compilation, data compression, or any workload that scales with cores and threads. Its 24 cores, 32 threads, and 36 MB of shared L3 cache provide the resources needed for sustained multi-threaded performance. The architecture differences reinforce this: the Core i9-14900T uses the Raptor Lake architecture on a 10 nm process node, while the Arc G3 EXTREME uses Panther Lake on a 3 nm node. The newer node helps the Arc G3 EXTREME in specific workloads, but it cannot overcome the raw core count advantage of the desktop chip.

The Arc G3 EXTREME is not without merit. Its wins in find prime numbers, physics, and single-thread tests show that the Panther Lake architecture has strengths in specific computational patterns. The 51.2% delta in find prime numbers is a substantial margin, and the 12% delta in physics indicates better performance in simulation-style workloads. The Arc G3 EXTREME also has a higher base clock of 1.90 GHz versus 1.10 GHz, which contributes to its single-thread advantage. However, these wins are isolated and do not translate into overall superiority.

Where Each One Wins

The Core i9-14900T wins in every Cinebench test, with deltas ranging from -15.4% to -57.2%. This makes it the definitive choice for 3D rendering, video encoding, and any application that relies on Cinebench-style multi-threaded performance. The 52.4% delta in Cinebench R23 multi-core is the single largest gap in the entire comparison, and the 57.2% delta in Cinebench R23 single-core shows that even lightly threaded rendering workloads favor the desktop chip. Data compression, integer math, random string sorting, and multi-threaded PassMark scores all go to the Core i9-14900T, covering the majority of productivity and server-style workloads.

The Arc G3 EXTREME wins in PassMark find prime numbers with a 51.2% delta, PassMark physics with a 12% delta, PassMark single-thread with a 6.9% delta, and PassMark extended instructions with a 1.5% delta. These wins suggest that the Arc G3 EXTREME is better suited for workloads involving prime number calculations, physics simulations, and certain instruction extensions. The single-thread win at 4293 versus 4016 indicates that the Arc G3 EXTREME has a slight edge in lightly threaded applications that do not rely on Cinebench's specific instruction patterns. The extended instructions win, though narrow, shows that the Panther Lake architecture handles certain SIMD-style workloads more efficiently.
