Intel Arc G3 vs Intel Processor U302L Comparison

Intel Arc G3 and Intel Processor U302L are two mobile processors from Intel that occupy different positions in the product stack. The database shows no direct head-to-head benchmark results for these two parts, and neither has recorded individual benchmark scores or nearest rivals. As a result, the analysis below relies on the architectural and specification data available in the database.

Where Each One Wins

The Intel Arc G3 is positioned for workloads that benefit from a high core count and fast memory. It uses 14 cores and 14 threads, while the Intel Processor U302L uses 5 cores and 6 threads. In multi-threaded tasks, such as video encoding, 3D rendering, or compiling code, the Arc G3 has a clear structural advantage because it can handle more parallel work. The database also shows the Arc G3 has a boost clock of 4.60 GHz, which is 2.20 GHz higher than the U302L’s 2.40 GHz boost. That higher boost clock helps single-threaded performance, so tasks like web browsing, office productivity, or light scripting will likely respond faster on the Arc G3.

The Intel Processor U302L wins in power efficiency and platform flexibility. Its TDP is 15, compared to the Arc G3’s 25. That makes the U302L more suitable for fanless or passively cooled designs, or for systems where battery life is prioritized over peak performance. The U302L also uses the Intel Socket 1700, which is a standard desktop-class socket, whereas the Arc G3 uses Intel BGA 2540, a soldered mobile socket. That difference means the U302L can be used in systems where the processor is replaceable or where the platform supports DDR4 or DDR5 memory. The Arc G3 only supports LPDDR5X, which is typically soldered and not upgradeable.

The U302L also uses 8 PCIe Gen 4 lanes for the CPU, while the Arc G3 uses 4 PCIe Gen 5 lanes. For peripheral connectivity, the U302L’s 8 lanes allow more simultaneous devices, such as multiple NVMe drives or expansion cards, even if the Gen 4 bandwidth per lane is lower than Gen 5. The Arc G3’s Gen 5 lanes offer higher per-lane bandwidth, but fewer lanes total.

Architecture Differences

The two processors come from different nodes and microarchitectures. The Intel Arc G3 is based on the Panther Lake codename, with a process node of 3 nm, fabricated by Intel. The Intel Processor U302L is based on Raptor Lake, specifically the Raptor Lake-PS variant, using a 10 nm process node, also from Intel. That process difference is significant: the 3 nm node allows more transistors in a given area and typically reduces power per operation, which is why the Arc G3 can run 14 cores at a 25 TDP while the U302L runs 5 cores at 15 TDP.

Cache hierarchies differ as well. The Arc G3 has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The U302L has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache. Per-core cache is larger on the Arc G3, which helps reduce memory latency for individual threads. Total L3 is also larger on the Arc G3, giving it more room to hold frequently accessed data across all cores.

Memory support is another distinguishing factor. The Arc G3 uses LPDDR5X in a dual-channel configuration, with a memory bandwidth of 136.5 GB/s. The U302L supports both DDR4 and DDR5, also dual-channel, but the database does not list a memory bandwidth figure for it. LPDDR5X is a low-power memory standard, so the Arc G3’s memory is optimized for mobile efficiency, while the U302L can use standard DIMMs or SO-DIMMs, which may be more cost-effective or higher capacity in some configurations.

Integrated graphics are different. The Arc G3 includes Arc B370 graphics, while the U302L includes UHD Graphics 80EU. The Arc B370 is a higher-tier integrated GPU, likely with more execution units and higher clock speeds, though the database does not specify those details. The UHD Graphics 80EU is a more basic integrated solution, suitable for display output and light media playback, but not for demanding graphics workloads.

The release dates also differ. The U302L was released on 2024-04-07, while the Arc G3 is newer, with a release date of 2026-05-27. The Arc G3 is the more recent design, which explains its newer process node and memory technology.

The Verdict

From the data, the Intel Arc G3 is the stronger processor for raw performance. It has more cores, more threads, higher base and boost clocks, more cache, faster memory bandwidth, and a newer process node. For any task that scales with core count or clock speed, the Arc G3 should outperform the U302L in both multi-threaded and single-threaded workloads. The 14 threads versus 6 threads is a 2.33x thread count advantage, and the 4.60 GHz boost versus 2.40 GHz is a 2.20 GHz clock advantage.

The Intel Processor U302L is the better fit for low-power or socket-based systems. Its 15 TDP is 10 lower than the Arc G3’s 25 TDP, which makes it easier to cool and more efficient for battery-powered devices. The Socket 1700 allows for user-replaceable processors, and the support for DDR4 and DDR5 gives platform memory flexibility. The 8 PCIe Gen 4 lanes also provide more expansion options than the Arc G3’s 4 Gen 5 lanes.

The launch MSRP for the U302L is $285, which is a listed price point, but no such figure exists for the Arc G3 in the database. The U302L also has a part number of SRPKGQ5CX, and the Arc G3 has a part number of SA4QZ.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results between the Intel Arc G3 and the Intel Processor U302L. Both processors have an avgBenchmarkScore of 0 and an empty benchmarks array. The winsA and winsB fields are both 0, indicating no test data exists in the database for direct comparisons.

Because there are no benchmark scores, the analysis must rely on the specification differences. The most significant gap is in core count: 14 versus 5. In a hypothetical multi-threaded benchmark, the Arc G3 would have nearly 2.8 times as many cores to work with. Even with lower per-core efficiency, that core count advantage typically translates to a large performance lead in parallel workloads. The Arc G3’s L3 cache is 18 MB versus 10 MB on the U302L, which further aids multi-threaded performance by reducing memory traffic.

In single-threaded tasks, the Arc G3’s boost clock of 4.60 GHz versus 2.40 GHz gives it a 2.20 GHz clock advantage. Higher clocks generally mean faster instruction execution, assuming similar instructions per clock. The Arc G3’s newer 3 nm process node also suggests it can maintain higher clocks while staying within its 25 TDP, whereas the U302L’s 10 nm node and 15 TDP limit its clock ceiling.

Memory bandwidth is another area where the Arc G3 leads. The database lists 136.5 GB/s for the Arc G3, while no figure is given for the U302L. That bandwidth figure is tied to the LPDDR5X memory type, which is optimized for high throughput in mobile systems. The U302L’s DDR4 or DDR5 support may or may not reach similar bandwidth depending on the specific memory modules used, but the database does not provide a comparable number.

The integrated graphics difference is also notable. The Arc B370 in the Arc G3 is a more capable GPU than the UHD Graphics 80EU in the U302L. For tasks like video playback, basic photo editing, or running older games, the Arc G3’s GPU should deliver better frame rates and smoother rendering. The UHD Graphics 80EU is sufficient for display output and simple 2D tasks, but it is not designed for heavy graphics work.
