Intel Arc G3 vs Intel Core i9-14900KS Comparison

Where Each One Wins

The benchmark data splits these two processors into entirely different performance domains. The Intel Core i9-14900KS holds every recorded benchmark win, with 19 individual test scores across Cinebench, Geekbench, and Passmark suites. The Intel Arc G3 has no benchmark entries in the database, so its wins cannot be quantified. This is not a close contest in raw performance; it is a comparison between a desktop flagship and a mobile processor with a different design purpose.

The use-case split is therefore stark. The Core i9-14900KS dominates multi-threaded workloads, as shown by its Cinebench R23 multicore score of 50995, a figure that places it in the 96th percentile of all CPUs in the database. Its Passmark multithread score of 60012 and Geekbench multicore score of 23931 reinforce this strength. For content creation, scientific computing, or any workload that scales across cores, the data indicates the i9-14900KS is the clear choice.

Single-thread performance also favors the i9-14900KS. Its Cinebench R23 single-core score of 7199 and Geekbench single-core score of 2692 show strong per-core capability. The Passmark single-thread score of 4815 confirms this pattern. The Arc G3, with no recorded benchmarks, cannot challenge any of these numbers.

The Arc G3 wins in a different category: power efficiency. Its TDP of 25 watts versus the i9-14900KS at 150 watts means the mobile part delivers usable performance at a fraction of the power draw. The database shows the Arc G3 targets the mobile segment with a BGA 2540 socket, while the i9-14900KS is a desktop part on Socket 1700. For laptops or compact systems where thermal limits and battery life matter, the Arc G3 has a structural advantage that no benchmark score can capture.

Architecture Differences

The two processors come from different Intel design families with distinct manufacturing approaches. The Arc G3 uses a 3 nm process node and carries the Panther Lake codename, while the Core i9-14900KS uses a 10 nm node with the Raptor Lake-R codename. This process gap explains the power envelope difference: the Arc G3 draws 25 watts, the i9-14900KS draws 150 watts.

Core counts differ substantially. The Arc G3 has 14 cores and 14 threads, meaning no hyperthreading. The i9-14900KS has 24 cores and 32 threads, indicating a hybrid arrangement of performance and efficiency cores with hyperthreading on the performance cluster. This 10-core and 18-thread advantage gives the i9-14900KS a structural lead in parallel workloads.

Cache hierarchies diverge as well. The Arc G3 offers 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 i9-14900KS doubles the L3 cache, which benefits workloads with large working sets, while the Arc G3 has larger per-core L1 and L2 allocations.

Clock speeds tell a similar story. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The i9-14900KS has a base clock of 3.20 GHz and a boost clock of 6.20 GHz. The 1.60 GHz boost advantage for the i9-14900KS contributes directly to its single-thread benchmark superiority.

Memory support differs completely. The Arc G3 uses LPDDR5X with dual-channel support and a recorded memory bandwidth of 136.5 GB/s. The i9-14900KS supports both DDR4 and DDR5, also dual-channel, but the database records no bandwidth figure. The i9-14900KS supports ECC memory, while the Arc G3 does not.

PCIe connectivity favors the desktop part. The i9-14900KS offers Gen 5 with 16 lanes, while the Arc G3 offers Gen 5 with only 4 lanes. The i9-14900KS also has an unlocked multiplier, whereas the Arc G3 is locked. The Arc G3 integrates an Arc B370 GPU, while the i9-14900KS integrates UHD Graphics 770.

Head-to-Head Benchmarks

The database contains 19 benchmark scores for the i9-14900KS and none for the Arc G3. Every comparison therefore shows the i9-14900KS ahead, with no opposing data points.

The largest single-thread margins appear in Cinebench tests. The i9-14900KS scores 7199 in Cinebench R23 single-core and 3023 in Cinebench R20 single-core. Its Cinebench R15 single-core score is 725. These numbers indicate the desktop part's 6.20 GHz boost clock delivers substantial per-thread throughput.

Multi-threaded results amplify the gap. The i9-14900KS records 50995 in Cinebench R23 multicore, 21417 in Cinebench R20 multicore, and 5140 in Cinebench R15 multicore. The 24-core, 32-thread configuration clearly drives these results, and the 36 MB shared L3 cache supports large parallel workloads.

Geekbench results follow the same pattern. The i9-14900KS scores 23931 in multicore and 2692 in single-core. These figures place it in the 96th percentile of all CPUs in the database, with an average benchmark score of 81127.

Passmark tests show the i9-14900KS excelling in specific workload types. Integer math scores 212644, floating point math scores 153975, and extended instructions score 45524. Data compression reaches 803368, while data encryption hits 47717. Random string sorting records 89789. Physics simulation scores 3381. The find prime numbers test shows 244, a lower figure that reflects the specific nature of that workload rather than overall weakness.

The nearest rivals in the database provide context for the i9-14900KS performance. The Intel Xeon w5-3535X scores 81115, a delta of 0 percent. The AMD Ryzen 9 8940HX scores 81103, also a delta of 0 percent. The AMD Ryzen AI Max+ PRO 395 scores 80762, a delta of 0.5 percent behind. The Intel Xeon 638 scores 80723, also 0.5 percent behind. These rivals cluster tightly around the i9-14900KS, confirming its position near the top of the performance distribution.

The Verdict

The data presents a straightforward choice based on workload and platform. The Intel Core i9-14900KS is the performance leader across every benchmark category in the database. Its 96th percentile ranking, 50995 Cinebench R23 multicore score, and 7199 single-core score make it suitable for heavy multi-threaded computing, high-refresh gaming, and demanding desktop applications. The 150 watt TDP and desktop socket indicate it belongs in a full-sized system with adequate cooling.

The Intel Arc G3 addresses a different requirement. Its 25 watt TDP, mobile BGA socket, and LPDDR5X memory support target portable computing. The 3 nm process node and Panther Lake architecture suggest modern efficiency-focused design. The 14 cores and 14 threads provide capable multi-tasking for mobile workloads. The 136.5 GB/s memory bandwidth is a recorded advantage for integrated graphics performance in a compact form factor.

Benchmark results cannot compare the two directly because the Arc G3 has no recorded scores. The i9-14900KS wins every measurable category by default. The Arc G3 wins on power efficiency, platform mobility, and process technology. Users requiring maximum compute performance should select the i9-14900KS. Users prioritizing battery life, portability, and low heat output should select the Arc G3. The database shows these are complementary products for different market segments, not direct competitors.
