Intel Arc G3 EXTREME vs Intel Core 9 273PE Comparison

Where Each One Wins

The benchmark split between these two processors is lopsided, with the Intel Core 9 273PE taking 13 of 17 recorded tests while the Intel Arc G3 EXTREME wins only 4. That count alone suggests a clear overall advantage for the desktop part, but the distribution of wins matters more than the raw tally. The Core 9 273PE dominates multi-threaded, memory-heavy, and floating-point workloads, while the Arc G3 EXTREME carves out a narrow niche in single-threaded PassMark tests, encryption, and prime-number finding.

The most decisive territory for the Core 9 273PE is rendering. In Cinebench R23 multicore, it scores 31288 against 14655 for the Arc G3 EXTREME, a 53.2% gap. The delta is even larger in Cinebench R23 singlecore, where the Core 9 273PE posts 4417 versus 1862, a 57.8% advantage. These are the largest margin wins in the entire head-to-head set, and they confirm that the desktop chip is the choice for heavily threaded and lightly threaded render workloads alike. The Arc G3 EXTREME does not come within 16% of the Core 9 273PE in any Cinebench test, and in the R23 variants it trails by more than half.

The Core 9 273PE also owns integer math. Its PassMark integer score of 139410 crushes the Arc G3 EXTREME's 71164, a 49% lead. This carries over to data compression, where the Core 9 273PE scores 405885 versus 307094, a 24.3% edge. Random string sorting also goes to the Core 9 273PE, with 45098 against 37331, a 17.2% margin. These results point to a processor that handles structured, branch-heavy workloads with far more headroom.

The Arc G3 EXTREME's wins are concentrated in specific, narrower tasks. Its PassMark single-thread score of 4293 beats the Core 9 273PE's 3650 by 17.6%. The same result appears twice in the database, confirming the consistency of that measurement. The Arc G3 EXTREME also wins data encryption, scoring 23881 against 22719, a 5.1% margin, and find prime numbers, scoring 248 versus 203, a 22.2% margin. These are respectable results, but they occupy a smaller slice of the workload spectrum.

The overall average benchmark scores reflect this split. The Core 9 273PE averages 49845 across its benchmark set, while the Arc G3 EXTREME averages 36699. The Core 9 273PE sits at the 90th percentile against all CPUs, while the Arc G3 EXTREME sits at the 85th. That 5-percentile gap is modest in the broader CPU landscape, but the head-to-head data shows where the separation comes from: sustained multi-core throughput and integer performance.

Architecture Differences

The two processors come from different Intel design families and target different market segments. The Arc G3 EXTREME is a Panther Lake part manufactured on a 3 nm process, while the Core 9 273PE is a Bartlett Lake part on a 10 nm process. Both are built by Intel, but the process node difference is substantial and explains part of the efficiency and density contrast between them.

Core and thread configurations diverge sharply. The Arc G3 EXTREME has 14 cores and 14 threads, so it runs without simultaneous multithreading. The Core 9 273PE has 12 cores and 24 threads, meaning each physical core supports two threads. Despite having two fewer physical cores, the Core 9 273PE presents twice as many logical threads to the operating system, which contributes heavily to its multi-core benchmark wins.

Clock speeds also favor the Core 9 273PE. Its base clock is 2.30 GHz and boost clock is 5.70 GHz, compared to 1.90 GHz base and 4.70 GHz boost for the Arc G3 EXTREME. The desktop part has a 1.00 GHz higher boost ceiling and a 0.40 GHz higher base clock. That advantage shows up directly in single-threaded Cinebench results, where the Core 9 273PE leads by 57.8% in R23 singlecore.

Cache hierarchies are organized differently. The Arc G3 EXTREME uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Core 9 273PE uses 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Core 9 273PE has exactly double the L3 capacity, which benefits workloads that cycle through large working sets. The Arc G3 EXTREME has larger per-core L1 and L2 allocations, which can help latency-sensitive single-threaded tasks.

Memory support differs as well. The Arc G3 EXTREME uses LPDDR5X with a dual-channel bus and 136.5 GB/s of bandwidth. The Core 9 273PE supports both DDR4 and DDR5 with a dual-channel bus and 89.6 GB/s of bandwidth. The mobile part has roughly 52% more memory bandwidth on paper, yet the Core 9 273PE still wins bandwidth-sensitive tests like data compression and random string sorting. That outcome suggests the Core 9 273PE's higher clocks and thread count compensate for its lower memory bandwidth.

The Core 9 273PE supports ECC memory, while the Arc G3 EXTREME does not. PCIe connectivity also differs: the Core 9 273PE offers Gen 5 with 16 lanes, while the Arc G3 EXTREME offers Gen 5 with 4 lanes. The desktop part has four times the CPU PCIe lane count, which matters for expansion in desktop platforms.

Integrated graphics differ as well. The Arc G3 EXTREME carries Arc B390 graphics, while the Core 9 273PE carries UHD Graphics 730. The market segments reflect this: the Arc G3 EXTREME is a mobile part on Intel BGA 2540, while the Core 9 273PE is a desktop part on Intel Socket 1700. Thermal design points also separate them, with the Arc G3 EXTREME rated at 25 W and the Core 9 273PE rated at 65 W. The production status for both is listed as active, with the Core 9 273PE releasing in March 2026 and the Arc G3 EXTREME in May 2026.
