Intel Arc G3
Intel Arc G3: The First Specialized Intel Processor for Portable Gaming PCs
AMD has been releasing specialized Ryzen Z processors for portable gaming PCs for several generations. Prior to the arrival of the Arc G3, manufacturers of such devices were using standard Intel Core Ultra laptop processors. The new series changes the approach: core configuration, graphics, and power management are initially designed for the gaming portable format.
Intel retained two performance P-cores, eight E-cores, and four low-power LP E-cores. This setup reduces the CPU load on the overall power limit and allows for a greater emphasis on integrated graphics.
The series includes the base Arc G3 with Arc B370 graphics and the higher-end Arc G3 Extreme with Arc B390. In terms of positioning, they are intended to compete with AMD Ryzen Z2 and Ryzen Z2 Extreme, respectively. However, independent tests have predominantly been published for the Extreme version so far.
What Sets Arc G3 Apart from G3 Extreme
| Characteristic | Intel Arc G3 | Intel Arc G3 Extreme |
|---|---|---|
| Maximum CPU Frequency | 4.6 GHz | 4.7 GHz |
| Integrated Graphics | Intel Arc B370 | Intel Arc B390 |
| Xe3 Cores | 10 | 12 |
| Maximum GPU Frequency | 2.2 GHz | 2.3 GHz |
The CPU configuration, cache size, and base power of the processors are identical. The main difference lies in the graphics: the base G3 has 16.7% fewer Xe-cores and a slightly lower maximum GPU frequency.
This does not imply the same level of gaming performance disparity. The actual difference will depend on power limits, memory speed, cooling, and specific device settings.
Why Does a Gaming Processor Have Only Two P-Cores?
The total number of cores in the Arc G3 appears impressive - 14 cores and 14 threads. However, only two cores belong to the performance class. The others are intended for background processes, multi-threaded tasks, and efficient operation under low load.
For rendering, compiling, and other heavy CPU loads, such a configuration may fall short compared to processors with four or six P-cores. In a portable gaming PC, the priorities are different: the CPU and GPU share a common power limit, and the final frame rate is often limited by the graphics.
Intel refers to this approach as right-sized compute. The processor part needs to be fast enough for gaming but not excessive for a battery-operated device.
Xe3 Graphics and XeSS 3
The main focus of the Arc G3 is on the integrated graphics of the Xe3 generation. The base Arc B370 features 10 Xe-cores, while the Arc B390 in the Extreme version has 12. Both support DirectX 12 Ultimate and hardware ray tracing.
Performance is further enhanced by the XeSS 3 technology, which includes image scaling, frame generation, and latency reduction. This is particularly important for portable PCs: in demanding games, the integrated graphics often have to output at a lower internal resolution to maintain an acceptable frame rate.
It’s worth noting that frame generation does not replace baseline performance. If a game is initially running slowly, the FPS counter may increase, but input lag and artifacts will still be noticeable. Therefore, the Arc G3 should be primarily evaluated based on results without frame generation.
Benchmarks: Only Arc G3 Extreme So Far
Currently, there are insufficient independent tests of the base Intel Arc G3. The first retail device with detailed results is the MSI Claw 8 EX AI+ featuring Arc G3 Extreme.
For comparison, the ASUS ROG Xbox Ally X with AMD Ryzen AI Z2 Extreme is included below. All results were obtained from one edition, although the exact power modes in the table are not disclosed. Therefore, the comparison reflects finished devices rather than just the processors installed in them.
| Device | Processor | Fire Strike | Time Spy | Steel Nomad | Port Royal |
|---|---|---|---|---|---|
| MSI Claw 8 EX AI+ | Intel Arc G3 Extreme | 12,358 | 6,534 | 1,425 | 3,544 |
| ASUS ROG Xbox Ally X | AMD Ryzen AI Z2 Extreme | 9,141 | 4,033 | 609 | 1,999 |
The MSI Claw outpaced the ASUS ROG Xbox Ally X in all four tests. Part of the difference may be related not only to the processor but also to power settings, memory, and cooling of the devices.
The largest lead was observed in Steel Nomad and Port Royal. The latter is particularly interesting as a ray tracing test, but the results still cannot be considered a pure comparison between Arc B390 and AMD graphics.
In gaming tests, the MSI Claw achieved 34 FPS in Black Myth: Wukong at 1080p with medium settings without XeSS. After enabling scaling, the result increased to 56 FPS. In Cyberpunk 2077 at 1080p and high settings, the device delivered 36.2 FPS without XeSS and 51.1 FPS with scaling.
These metrics cannot be directly translated to a standard Arc G3. The lower version has fewer graphic blocks and a lower maximum GPU frequency. How significant the difference will be in real games can only be demonstrated through tests of devices with Arc B370.
Performance Under Power Constraints
For the Arc G3, what matters more is not peak performance but performance within the 15-25 W power range. It is within this range that a portable device must balance FPS, heat, noise, and battery life.
Currently, there are no comparable tests of the base G3 and Ryzen Z2 under the same power limit. Therefore, assessing the effectiveness of the lower model and its standing against AMD is not yet possible.
Devices Featuring Intel Arc G3
Intel has named three initial series of portable gaming PCs based on the new platform:
- Acer Predator Atlas 8 - configurations with Arc G3 and Arc G3 Extreme;
- MSI Claw 8 EX AI+ - Arc G3 Extreme;
- OneXPlayer - models on Arc G3 Extreme.
MSI was the first to release a device available for full independent testing. Acer is more crucial for evaluating the base Arc G3: the lower configuration of the Predator Atlas 8 should indicate how Arc B370 compares to B390 and whether it can compete with standard Ryzen Z2.
Conclusion
Arc G3 is not a new type of processor for the entire market, but a delayed yet logical response from Intel to the AMD Ryzen Z family. Previously, manufacturers of portable gaming PCs used general-purpose Core Ultra. Now, the core configuration, power management, and graphics have been initially designed for handheld devices.
In the first tests, the MSI Claw with G3 Extreme significantly outperformed the ASUS ROG Xbox Ally X with Ryzen AI Z2 Extreme. However, this is a comparison of two finished devices, not a pure check of processors under identical power conditions.
The base Arc G3 remains a model without full independent testing. Based on specifications, Arc B370 should moderately lag behind B390, but its actual suitability for gaming at 1080p will only become clear after tests of retail devices.
