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

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core i9-14900KS, which wins 16 of the 17 recorded head-to-head comparisons. The Intel Arc G3 EXTREME manages a single win, but the margin of that win is extremely narrow, while the i9-14900KS frequently wins by massive double-digit percentage margins.

The largest gap in the entire comparison appears in Cinebench R23 multi-core, where the i9-14900KS scores 50,995 points against 14,655 for the Arc G3 EXTREME. That represents a 71.3% advantage for the desktop part. The single-core version of the same test shows a 74.1% delta, with the i9-14900KS scoring 7,199 versus 1,862. These two results alone establish the i9-14900KS as the clear performance leader in both heavily threaded and lightly threaded rendering workloads.

Cinebench R15 and R20 results follow the same pattern. In R15 multi-core, the i9-14900KS scores 5,140 against 2,192, a 57.4% difference. The single-core R15 result shows 725 versus 267, a 63.2% delta. In R20, both multi-core and single-core tests show a 48.9% advantage for the i9-14900KS, with scores of 21,417 versus 10,945 and 3,023 versus 1,545 respectively.

PassMark tests reinforce the trend. Data compression shows the i9-14900KS at 803,368 against 307,094, a 61.8% delta. Integer math delivers a 66.5% edge, with the i9-14900KS scoring 212,644 versus 71,164. Random string sorting shows a 58.4% gap, with scores of 89,789 and 37,331. Multithread performance sits at 60,012 versus 30,659, a 48.9% difference. Floating point math shows a 43.5% delta, with 153,975 against 86,929.

The smaller single-thread PassMark gaps are still meaningful. PassMark single-thread shows 4,815 versus 4,293, a 10.8% advantage for the i9-14900KS. Data encryption shows 47,717 against 23,881, a 50% delta. Extended instructions show 45,524 versus 24,017, a 47.2% gap. Physics testing shows 3,381 versus 2,515, a 25.6% difference.

The one test the Arc G3 EXTREME wins is PassMark find prime numbers, where it scores 248 against 244. The 1.6% margin is within run-to-run noise for most benchmark suites, so this result does not indicate a meaningful advantage in any practical workload. It remains the only recorded win for the mobile part across the entire comparison set.

The Verdict

The data separates these two processors into completely different performance classes. The Intel Core i9-14900KS sits in the 96th percentile of all CPUs in the database, while the Intel Arc G3 EXTREME sits in the 85th percentile. The average benchmark score for the i9-14900KS is 81,127, which places it alongside the Intel Xeon w5-3535X and AMD Ryzen 9 8940HX, both within 0% delta. The Arc G3 EXTREME averages 36,699, with its nearest rivals being the Intel Core Ultra 5 225 at 0.6% higher, the AMD Ryzen 5 5600F at 0.7% higher, the AMD Ryzen 5 5500X3D at 0.9% higher, and the AMD Ryzen AI 7 PRO 450 at 1.1% higher.

Anyone selecting a processor for desktop rendering, content creation, or heavily threaded productivity work should choose the i9-14900KS based on these numbers. The multi-core Cinebench results show a 71.3% advantage in R23, and the PassMark multithread score is 95.8% higher than the Arc G3 EXTREME's total. The single-core advantage is smaller but still substantial, ranging from 10.8% in PassMark to 74.1% in Cinebench R23 single-core.

The Arc G3 EXTREME is a mobile part on an Intel BGA 2540 socket with a 25 TDP. Its performance profile places it in the mid-range of the database, but it is not competitive with the top-end desktop flagship in any benchmark except the trivial prime number test. The data shows no scenario where the Arc G3 EXTREME delivers better performance for the same workload, so the choice depends entirely on platform and power constraints rather than raw capability.

Architecture Differences

The two processors come from different Intel families and target different market segments. The Arc G3 EXTREME uses the Panther Lake codename and belongs to the Arc G3 generation. It is built on a 3 nm process at Intel's foundry. The i9-14900KS uses the Raptor Lake-R codename, belongs to the Core 14th Gen series, and is built on a 10 nm process. The die size for the i9-14900KS is 257 mm², while no die size is recorded for the Arc G3 EXTREME.

Core and thread counts differ substantially. The Arc G3 EXTREME has 14 cores and 14 threads, meaning no hyper-threading is enabled. The i9-14900KS has 24 cores and 32 threads, indicating a hybrid configuration with performance and efficiency cores. The i9-14900KS also has an unlocked multiplier, while the Arc G3 EXTREME does not.

Cache layouts are different as well. The Arc G3 EXTREME has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The i9-14900KS has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The desktop part has double the total L3 capacity, which contributes to its performance advantage in memory-sensitive workloads.

Integrated graphics differ. The Arc G3 EXTREME uses Arc B390 graphics, while the i9-14900KS uses UHD Graphics 770. The memory controllers differ too: the Arc G3 EXTREME supports LPDDR5X memory, while the i9-14900KS supports both DDR4 and DDR5. The Arc G3 EXTREME has a recorded memory bandwidth of 136.5 GB/s, while no bandwidth figure is recorded for the i9-14900KS. ECC memory support is present on the i9-14900KS but absent on the Arc G3 EXTREME.

Where Each One Wins

The Intel Core i9-14900KS wins every meaningful benchmark category. Its largest advantages come in Cinebench R23 multi-core at 71.3% and Cinebench R23 single-core at 74.1%. These results indicate the desktop part delivers substantially higher performance in rendering, simulation, and any workload that scales with both core count and per-core speed. The PassMark integer math result at 66.5% and data compression at 61.8% further confirm its dominance in productivity and data processing tasks.

The Arc G3 EXTREME's only win is the prime number calculation test, with a 1.6% margin. This is too small to be considered a practical advantage. The mobile part does offer a significantly lower TDP of 25 versus 150, which makes it suitable for thermally constrained systems, but the performance cost is severe: the i9-14900KS scores 95.8% higher in PassMark multithread and 248% higher in Cinebench R23 multi-core.

For desktop builders seeking maximum performance, the i9-14900KS is the clear choice from the data. For mobile platforms where power and cooling are limited, the Arc G3 EXTREME provides a functional but much slower alternative. The benchmark results show no workload category where the Arc G3 EXTREME approaches the i9-14900KS's performance, and the only statistical win is effectively a tie in a single specialized test.
