Architecture Differences

The two processors represent fundamentally different design approaches from Intel. The Intel Arc G3 EXTREME is built on Panther Lake architecture using a 3 nm process node, fabricated by Intel. The Intel Core 5 221E uses Bartlett Lake architecture on a 10 nm process node, also fabricated by Intel, with a die size of 257 mm². The process node difference is substantial, with the Arc G3 EXTREME using a notably more advanced manufacturing process.

Core configuration reveals an interesting split. Both processors have 14 cores, but the thread counts differ: the Arc G3 EXTREME has 14 threads (one thread per core), while the Core 5 221E has 20 threads. This means the Core 5 221E leverages simultaneous multithreading to extract more work from its cores, while the Arc G3 EXTREME operates without it. The base clock rates differ as well, with the Arc G3 EXTREME at 1.90 GHz and the Core 5 221E at 2.70 GHz. Boost clocks also favor the Core 5 221E at 5.20 GHz versus 4.70 GHz.

Cache hierarchies diverge significantly. The Arc G3 EXTREME provides 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with 18 MB of shared L3 cache. The Core 5 221E has 80 KB of L1 cache per core and 2 MB of L2 cache per core, but a larger 24 MB of shared L3 cache. The total cache picture is mixed: the Arc part has more per-core L1 and L2, while the Core 5 221E has more shared L3.

Memory support and I/O capabilities differ in ways that reflect their target platforms. The Arc G3 EXTREME uses LPDDR5X memory on a dual-channel bus with 136.5 GB/s of bandwidth. The Core 5 221E supports DDR4 and DDR5 on a dual-channel bus with 89.6 GB/s of bandwidth. PCIe connectivity strongly favors the Core 5 221E, which provides Gen 5 with 16 lanes, while the Arc G3 EXTREME provides Gen 5 with only 4 lanes. Integrated graphics also differ: the Arc G3 EXTREME includes Arc B390 graphics, while the Core 5 221E includes UHD Graphics 730.

Power characteristics show a major divergence. The Arc G3 EXTREME has a TDP of 25 watts, while the Core 5 221E has a TDP of 65 watts. The release dates also differ, with the Core 5 221E released on January 12, 2025, and the Arc G3 EXTREME released on May 27, 2026. The Core 5 221E has a launch MSRP of $232.

The Verdict

The data supports a clear split based on workload and platform. The Intel Core 5 221E is the stronger processor for sustained multi-core rendering workloads, as shown by its 43.5% lead in Cinebench R23 multicore and its 16.1% lead in Cinebench R15 multicore. It also dominates integer math, scoring 117813 against 71164, a 39.6% advantage. For users on a desktop platform with a Socket 1700 motherboard, DDR4 or DDR5 memory support, and a need for ECC memory, the Core 5 221E is the appropriate choice.

The Intel Arc G3 EXTREME counters with wins in several specialized computational areas. It leads by 31.8% in extended instructions, 43.4% in prime number finding, 24.3% in data encryption, 10% in floating point math, and 12.8% in physics. Its single-thread PassMark score of 4293 edges out the Core 5 221E's 4147. The Arc G3 EXTREME also wins the Cinebench R20 tests, though by a slim 0.5% margin in both multicore and singlecore. Its 25 watt TDP and mobile BGA 2540 socket position it for power-constrained mobile systems, and its 136.5 GB/s memory bandwidth gives it an advantage in memory-throughput-sensitive tasks.

The average benchmark scores place the Core 5 221E ahead overall (40144 versus 36699), and its nearest rival comparisons confirm its standing: it sits within 0.4% of the Intel Core i9-13905H and 0.3% of the AMD Ryzen 9 270. The Arc G3 EXTREME's nearest rivals, including the Intel Core Ultra 5 225 and AMD Ryzen 5 5600F, are all within 1.1% of its average score, indicating a competitive field around its performance level.
