Intel Arc G3 vs Intel Core i7-14650HX Comparison

Head-to-Head Benchmarks

The database provides no recorded benchmark scores for the Intel Arc G3, while the Intel Core i7-14650HX has a substantial set of measurements. This makes a direct score-for-score comparison impossible. The Arc G3's benchmark array is empty, meaning the data cannot show any wins for that processor. The Core i7-14650HX, by contrast, delivers a full suite of results across Cinebench, Geekbench, and Passmark tests.

The Core i7-14650HX's Cinebench scores establish a clear performance baseline. It records 3470.5 in Cinebench R15 multicore, 11946 in R20 multicore, and 20454 in R23 multicore. Single-core results follow with 285.5 in R15, 1686 in R20, and 1969 in R23. Geekbench adds 14249 multicore and 2173 single-core. Passmark tests show 33495 in multithread and 3841 in single-thread, alongside specialized workloads like 398418 in data compression, 22917 in data encryption, and 24150 in extended instructions. The floating-point math score is 84999, integer math reaches 116661, and physics hits 2202. Random string sorting scores 43035, while finding prime numbers records just 152.

The Arc G3's lack of benchmarks means its aggregate percentile sits at 50 among all CPUs, while the Core i7-14650HX reaches the 88th percentile. The average benchmark score tells the same story: 0 for the Arc G3 versus 41576 for the Core i7-14650HX. In the nearest rivals comparison, the Core i7-14650HX sits nearly level with the Intel Core Ultra 7 265H, which scores 41621 and trails by only 0.1 percent. The Intel Core 7 251TE scores 41650, a 0.2 percent lead over the i7-14650HX. The AMD Ryzen 9 5900X scores 41376, which the i7-14650HX beats by 0.5 percent. The Intel Core i7-12850HX scores 41779, putting it 0.5 percent ahead.

These rival deltas place the Core i7-14650HX in a tightly contested performance band. The recorded data shows no comparable figures for the Arc G3, so any head-to-head analysis must rely on architectural specifications rather than measured outcomes.

Architecture Differences

The two processors come from distinct Intel design families. The Arc G3 uses the Panther Lake codename and is built on a 3 nm process node, manufactured by Intel. The Core i7-14650HX uses the Raptor Lake architecture with the Raptor Lake-HX codename, built on a 10 nm node, also by Intel. The die size for the Core i7-14650HX is 257 mm², while the Arc G3's die size is not recorded.

Core and thread counts differ significantly. The Arc G3 has 14 cores and 14 threads, meaning no hyperthreading. The Core i7-14650HX has 16 cores and 24 threads, indicating 8 performance cores with hyperthreading and 8 efficiency cores without. Clock speeds favor the Core i7-14650HX: it bases at 2.20 GHz and boosts to 5.20 GHz, while the Arc G3 bases at 1.90 GHz and boosts to 4.60 GHz.

Cache layouts diverge sharply. The Arc G3 allocates 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Core i7-14650HX uses 80 KB of L1 per core, 2 MB of L2 per core, and a larger 30 MB of shared L3. The Arc G3's larger per-core L1 and L2 suggest a different design intent, possibly favoring more local data access per core, while the Core i7-14650HX's larger L3 pool benefits shared workloads across more threads.

Memory support separates the two clearly. The Arc G3 supports LPDDR5X with a dual-channel bus and a recorded memory bandwidth of 136.5 GB/s. The Core i7-14650HX supports DDR4 and DDR5, also dual-channel, but its memory bandwidth is not recorded. ECC memory is absent on the Arc G3 and present on the Core i7-14650HX. PCIe lanes also differ: the Arc G3 provides Gen 5 with 4 lanes (CPU only), while the Core i7-14650HX provides Gen 5 with 16 lanes (CPU only).

Integrated graphics differ as well. The Arc G3 carries Arc B370 graphics, while the Core i7-14650HX uses UHD Graphics 710. The release dates place the Core i7-14650HX in January 2024 and the Arc G3 in May 2026, roughly two years apart. The Core i7-14650HX has an unlocked multiplier, while the Arc G3 does not. Both target the mobile market segment and carry active production status.

Where Each One Wins

Based on recorded data, the Core i7-14650HX wins in every measurable benchmark category. The Arc G3 has no scores, so no wins can be attributed to it. The Core i7-14650HX's high percentile rank of 88 against all CPUs indicates strong overall performance, while the Arc G3's neutral 50th percentile reflects the absence of recorded measurements rather than actual performance.

The Core i7-14650HX's strengths emerge from its thread count and clock speeds. With 24 threads and a 5.20 GHz boost, it handles heavily threaded workloads like Cinebench R23 multicore, where it scores 20454. The Geekbench multicore score of 14249 reinforces this. Passmark multithread at 33495 and integer math at 116661 show similar patterns. Single-thread performance is also solid, with Geekbench single-core at 2173 and Passmark single-thread at 3841.

The Arc G3's 14 threads and lower 4.60 GHz boost suggest it targets a different power envelope. Its 25 watt TDP versus the Core i7-14650HX's 55 watt TDP indicates the Arc G3 prioritizes efficiency. The 3 nm process node and LPDDR5X memory support point toward a low-power design, likely suited for thin-and-light mobile systems. The Core i7-14650HX, with its 55 watt TDP and larger die, is positioned for high-performance laptops where power draw is less constrained.

The Arc G3's larger per-core caches (192 KB L1, 2.5 MB L2) could benefit latency-sensitive workloads if benchmark data existed. Its 136.5 GB/s memory bandwidth, while recorded, cannot be compared to the Core i7-14650HX because that figure is missing. The Arc B370 integrated graphics may outperform UHD Graphics 710 for light graphics tasks, but no benchmark confirms this.

The Verdict

The recorded data offers no benchmark results for the Intel Arc G3, so its performance cannot be assessed from measurements. The Intel Core i7-14650HX delivers a full benchmark suite with an 88th percentile ranking and an average score of 41576. Its nearest rivals, the Intel Core Ultra 7 265H and Intel Core 7 251TE, sit within 0.2 percent, indicating the i7-14650HX performs at the top of its immediate competitive set.

The specification differences point to different design goals. The Core i7-14650HX uses more cores, more threads, higher clocks, and a larger L3 cache, all supporting higher throughput in multi-threaded workloads. Its 55 watt TDP and 257 mm² die confirm a high-performance orientation. The Arc G3 uses a more advanced 3 nm node, lower TDP, and faster memory standard (LPDDR5X with recorded bandwidth), suggesting an efficiency-focused design for mobile systems where power and thermals matter more than raw compute.

For users prioritizing measured performance, the Core i7-14650HX is the only option with data to support a choice. The Arc G3's empty benchmark record means no objective comparison is possible. The Core i7-14650HX's 16 lanes of PCIe Gen 5 also provide greater expansion capability than the Arc G3's 4 lanes. ECC memory support on the Core i7-14650HX adds another capability absent from the Arc G3. The unlocked multiplier on the Core i7-14650HX allows overclocking, while the Arc G3 is locked.

The Core i7-14650HX stands as the data-backed choice for high-performance mobile computing. The Arc G3 remains an unmeasured quantity, with specifications that suggest a lower-power alternative but no recorded evidence of competitive performance.
