Intel Arc G3 vs Intel Core 7 150UL Comparison

The Verdict

The recorded data presents a clear split between two Intel processors aimed at different physical envelopes. The Intel Arc G3, built on Panther Lake, is a 14-core, 14-thread mobile part with a 25 W TDP, a 3 nm process node, and a 4.60 GHz boost clock. The Intel Core 7 150UL, built on Raptor Lake-PS, is a 10-core, 12-thread desktop part with a 15 W TDP, a 10 nm process node, and a 5.00 GHz boost clock. Neither chip has benchmark scores in the database, meaning the verdict rests entirely on architectural and specification differences rather than measured performance deltas.

The Arc G3 offers a higher core count, a larger shared L3 cache (18 MB vs. 12 MB), a more advanced process node (3 nm vs. 10 nm), faster memory bandwidth (136.5 GB/s vs. no recorded figure for the Core 7), and PCIe Gen 5 support, albeit with only 4 CPU lanes. The Core 7 150UL counters with a higher boost clock (5.00 GHz vs. 4.60 GHz), a lower TDP (15 W vs. 25 W), double the PCIe lanes for the CPU (8 lanes vs. 4 lanes), and support for both DDR4 and DDR5 memory, whereas the Arc G3 is limited to LPDDR5X.

For a system builder prioritizing raw multi-threaded throughput and modern memory bandwidth, the Arc G3 appears structurally superior, with 4 additional cores, 2 additional threads, and 6 MB more shared L3 cache. For a use case that demands the highest single-thread boost frequency or a lower thermal envelope, the Core 7 150UL holds the advantage, with a 0.40 GHz higher boost clock and a 10 W lower TDP. The data does not include benchmark scores, so the choice depends on which specification category matters more: core count and cache capacity versus clock speed and power draw.

Architecture Differences

The two processors diverge at the process node level. The Arc G3 uses a 3 nm process fabricated by Intel, while the Core 7 150UL uses a 10 nm process, also from Intel. This node gap suggests the Arc G3 should deliver higher transistor density and improved power efficiency per watt, though the Arc G3's TDP is actually 10 W higher than the Core 7's (25 W vs. 15 W). The Arc G3 is codenamed Panther Lake and belongs to the Arc G3 generation, while the Core 7 150UL is codenamed Raptor Lake-PS and belongs to the Core 7 generation. No architecture name is recorded for the Arc G3, but the Core 7 150UL explicitly lists Raptor Lake as its architecture.

Core and cache layouts differ substantially. The Arc G3 packs 14 cores and 14 threads, with 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Core 7 150UL has 10 cores and 12 threads, with 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. The Arc G3 doubles the per-core L1 and L2 allocations and provides 50% more shared L3 cache. The thread count delta (14 vs. 12) indicates that the Arc G3 implements a purely single-thread-per-core design, while the Core 7 150UL has 2 cores with hyper-threading.

Memory architecture is another key separator. The Arc G3 supports LPDDR5X memory over a dual-channel bus with a recorded bandwidth of 136.5 GB/s. The Core 7 150UL supports both DDR4 and DDR5 over a dual-channel bus, but no memory bandwidth figure is recorded in the database. The Core 7's broader memory compatibility may appeal to upgrade paths, while the Arc G3's fixed LPDDR5X support trades flexibility for a specified bandwidth ceiling.

PCIe capabilities differ in generation and lane count. The Arc G3 offers PCIe Gen 5 with 4 CPU lanes, while the Core 7 150UL offers PCIe Gen 4 with 8 CPU lanes. The Arc G3's newer PCIe generation enables higher per-lane bandwidth, but the Core 7 provides double the lane count, which can matter for devices that require multiple simultaneous connections. Integrated graphics also differ: the Arc G3 carries an Arc B370 iGPU, while the Core 7 150UL carries Iris Xe Graphics with 96 execution units. No benchmark data is available to quantify the performance gap between these iGPU solutions.

Head-to-Head Benchmarks

The database contains no benchmark scores for either processor, and the head-to-head benchmark array is empty. This means there are no measured performance numbers to compare, no win counts (winsA is 0, winsB is 0), and no nearest rivals with scores or delta percentages. The analysis must therefore rely on specification-level indicators rather than empirical results.

The biggest structural win for the Arc G3 is its core and cache advantage. With 14 cores versus 10, it offers 40% more cores. Its L3 cache of 18 MB is 50% larger than the Core 7's 12 MB. Per-core L2 cache is exactly double (2.5 MB vs. 1.25 MB), and per-core L1 cache is 192 KB versus 80 KB, a 140% increase. These differences suggest the Arc G3 should handle multi-threaded workloads with more resident data and more parallel execution units, assuming the software can utilize all 14 threads.

The biggest win for the Core 7 150UL is clock speed and power. Its 5.00 GHz boost is 8.7% higher than the Arc G3's 4.60 GHz, which typically translates to faster single-thread execution for latency-sensitive tasks. Its 15 W TDP is 40% lower than the Arc G3's 25 W, making it the more power-frugal option in the pair. The Core 7 also has 8 PCIe Gen 4 CPU lanes versus 4 PCIe Gen 5 lanes on the Arc G3, giving it double the lane count for multi-device connectivity, though the Arc G3's Gen 5 standard offers higher per-lane bandwidth.

Memory bandwidth favors the Arc G3 with a recorded 136.5 GB/s, a figure entirely absent for the Core 7. The Arc G3's LPDDR5X support is a single memory type, while the Core 7 supports both DDR4 and DDR5, which grants the Core 7 flexibility but no recorded bandwidth number to compare. The Arc G3's memory controller is paired with a 3 nm process, while the Core 7's is on 10 nm, suggesting the Arc G3 may achieve better memory latency characteristics, though this is not measured in the database.

Where Each One Wins

The Arc G3 wins on raw compute capacity. It leads in core count, thread count, per-core L1 cache, per-core L2 cache, shared L3 cache, memory bandwidth, PCIe generation, and process node. These attributes point toward workloads that scale with parallelism and cache size: compilation, rendering, scientific simulations, or any multi-threaded application that benefits from a 50% larger L3 pool. The 3 nm process further suggests the Arc G3 can pack more transistors into the same die area, potentially improving performance per clock in addition to raw core count.

The Core 7 150UL wins on clock speed and efficiency. Its 5.00 GHz boost clock exceeds the Arc G3's 4.60 GHz by 0.40 GHz, which favors single-threaded responsiveness in everyday applications, legacy software, or lightly threaded games. Its 15 W TDP is 10 W lower than the Arc G3's, making it the better fit for thermally constrained desktop builds or always-on systems where power draw is a primary concern. The Core 7's 8 PCIe Gen 4 lanes also give it an advantage for systems that need to attach multiple PCIe devices directly to the CPU, despite the older generation.

The Arc G3's mobile segment and BGA 2540 socket indicate it is designed for compact, soldered platforms, while the Core 7's desktop segment and Socket 1700 indicate a replaceable CPU for standard desktop boards. The Core 7's dual memory support (DDR4 and DDR5) makes it more adaptable to existing platforms, whereas the Arc G3's LPDDR5X-only support is tuned for integrated, low-power mobile designs. The Arc G3's release date of 2026-05-27 is over two years later than the Core 7's 2024-04-07, so the Arc G3 benefits from a more recent design cycle.

In summary, the data shows no measured performance winner. The Arc G3 is the choice for maximum multi-threading, cache capacity, memory bandwidth, and process technology. The Core 7 150UL is the choice for higher boost clocks, lower power draw, broader memory compatibility, and more PCIe lanes. Without benchmark scores, the recorded specifications are the only basis for differentiation.
