Intel Arc G3 EXTREME vs Intel Core i7-14700 Comparison

The Verdict

The Intel Core i7-14700 is the decisive winner in the recorded benchmark data, taking 13 of 17 head-to-head tests. Its average benchmark score of 52301 places it in the 91st percentile of all CPUs, while the Intel Arc G3 EXTREME sits at 36699 and the 85th percentile. The desktop part wins by substantial margins in nearly every heavy multi-threaded workload, including Cinebench R23 multi-core at 28398 versus 14655, a 48.4% lead. For users running rendering, compression, encryption, or integer-heavy tasks, the i7-14700 is the clear choice from the data.

The Intel Arc G3 EXTREME wins only 4 tests, but they are notable: prime number finding, physics simulation, and single-thread Passmark tests. Its single-thread Passmark score of 4293 slightly edges the i7-14700's 4236, a 1.3% advantage. The mobile chip also dominates in prime number search, scoring 248 versus 164, a 51.2% gap. These wins suggest the Panther Lake architecture has specific strengths in certain scalar workloads, but the overall picture favors the i7-14700.

The verdict is straightforward. Desktop users with workloads that scale across cores should pick the i7-14700. Mobile users who need occasional single-thread performance and low power consumption should consider the Arc G3 EXTREME, but only if their tasks align with its narrow set of wins. The data does not support choosing the Arc G3 EXTREME for general productivity or creative work.

Architecture Differences

The two processors come from different Intel product lines and target different market segments. The Intel Arc G3 EXTREME is a mobile part on Intel BGA 2540, built on a 3 nm process with the Panther Lake codename. It belongs to the Arc G3 generation. The Intel Core i7-14700 is a desktop processor on Intel Socket 1700, using a 10 nm process with Raptor Lake-R architecture and the Core i7 (Raptor Lake Refresh) generation.

The core counts differ significantly. The Arc G3 EXTREME has 14 cores and 14 threads, with no hyper-threading. The i7-14700 has 20 cores and 28 threads, meaning 8 of its cores support additional threads. This thread advantage drives many of the multi-core benchmark results.

Cache layouts also differ. The Arc G3 EXTREME uses 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. The i7-14700 uses 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The i7's larger shared L3 helps in workloads with large working sets.

Clock speeds favor the desktop chip. The i7-14700 has a base clock of 2.10 GHz and boost clock of 5.40 GHz. The Arc G3 EXTREME runs at 1.90 GHz base and 4.70 GHz boost. The i7 also has a larger die at 257 mm², while the Arc's die size is not recorded.

Memory support differs. The i7-14700 supports DDR4 and DDR5, while the Arc G3 EXTREME supports LPDDR5X. The i7 has ECC memory support, which the Arc lacks. Memory bandwidth is recorded only for the Arc at 136.5 GB/s. Both use dual-channel memory buses.

PCIe connectivity differs. The i7-14700 provides 16 PCIe Gen 5 lanes, while the Arc G3 EXTREME provides only 4. The integrated graphics also differ: Arc B390 on the mobile chip versus UHD Graphics 770 on the desktop chip.

The i7-14700 has a launch MSRP of $384. The Arc G3 EXTREME has no recorded launch MSRP. The desktop part released in 2024-01-07, while the mobile part released later on 2026-05-27. Both are currently active in production. Neither has an unlocked multiplier.

Head-to-Head Benchmarks

The Cinebench suite shows the i7-14700's dominance in rendering workloads. In Cinebench R15 multi-core, the i7 scores 4061 against 2192, a 46% advantage. In R20 multi-core, the gap narrows to 23.9% with scores of 14388 versus 10945. The R23 multi-core test shows the largest gap at 48.4%, with 28398 versus 14655. Single-core Cinebench results also favor the i7, but by smaller margins: 10.7% in R15 (299 vs 267), 23.9% in R20 (2031 vs 1545), and 10.5% in R23 (2080 vs 1862).

Passmark results follow a similar pattern. Data compression heavily favors the i7-14700, scoring 498198 versus 307094, a 38.4% lead. Data encryption shows a 19.3% gap (29601 vs 23881). Extended instructions favor the i7 by 15.4% (28388 vs 24017). Floating point math shows an 18.5% gap (106716 vs 86929). Integer math is the largest Passmark loss for the Arc, with the i7 scoring 154535 versus 71164, a 53.9% advantage. Random string sorting favors the i7 by 31.3% (54340 vs 37331). Multi-thread Passmark shows a 24% gap (40318 vs 30659).

The Arc G3 EXTREME wins four tests. Prime number finding shows a 51.2% advantage, scoring 248 versus 164. Physics simulation favors the Arc by 13% (2515 vs 2226). The single-thread Passmark test shows a narrow 1.3% win (4293 vs 4236), and the duplicate singlethread test records the same result. These wins indicate the Panther Lake architecture has strengths in specific scalar and physics workloads, but they do not offset the i7's multi-core advantages.

The average benchmark scores confirm the overall gap. The i7-14700 averages 52301, while the Arc G3 EXTREME averages 36699. The nearest rivals for the i7 include the Intel Xeon Gold 5320H (0.2% lower), AMD EPYC 8124P (0.3% higher), and Intel Core Ultra 5 235HX (0.4% higher). The Arc's nearest rivals include the Intel Core Ultra 5 225 (0.6% lower), AMD Ryzen 5 5600F (0.7% lower), and AMD Ryzen 5 5500X3D (0.9% lower).

Where Each One Wins

The Intel Core i7-14700 wins in all rendering workloads. Cinebench R15, R20, and R23 multi-core tests show advantages from 23.9% to 48.4%. The R23 multi-core result of 28398 is nearly double the Arc's 14655. This makes the i7 the choice for 3D rendering and video encoding tasks that rely on multi-threaded CPU performance.

The i7 also wins in data processing workloads. Data compression shows a 38.4% advantage (498198 vs 307094). Integer math shows the largest gap at 53.9% (154535 vs 71164). Floating point math favors the i7 by 18.5% (106716 vs 86929). Random string sorting shows a 31.3% gap (54340 vs 37331). Extended instructions favor the i7 by 15.4% (28388 vs 24017). Data encryption shows a 19.3% gap (29601 vs 23881). These results indicate the i7 is better for database work, file compression, and scientific computing.

The Intel Arc G3 EXTREME wins in prime number finding with a 51.2% advantage (248 vs 164). This suggests the Panther Lake architecture handles certain scalar integer operations more efficiently. Physics simulation favors the Arc by 13% (2515 vs 2226), which could benefit mobile gaming or lightweight simulation tasks. The single-thread Passmark win of 1.3% (4293 vs 4236) shows the mobile chip has competitive per-core performance despite its lower clock speed.

The market segments clarify the use cases. The Arc G3 EXTREME is a mobile processor with 25 W TDP, suited for thin laptops where power efficiency matters. The i7-14700 is a desktop part with 65 W TDP, designed for systems with adequate cooling and power delivery. The i7's 16 PCIe Gen 5 lanes support expansion cards, while the Arc's 4 lanes limit connectivity.

The data does not support using the Arc G3 EXTREME as a general-purpose replacement for the i7-14700. Its wins are narrow and specific. The i7's 13 wins cover the broad categories of rendering, compression, encryption, and math operations. The Arc's 4 wins cover prime number finding, physics, and a marginal single-thread advantage. Users with workloads matching the Arc's strengths may find it adequate, but the i7-14700 is the better all-around performer according to the recorded benchmarks.
