Intel Arc G3 EXTREME vs Intel Core i5-14600T Comparison

Head-to-Head Benchmarks

The Intel Arc G3 EXTREME and Intel Core i5-14600T present two very different performance profiles. Across the 17 recorded head-to-head benchmarks, the Arc G3 EXTREME claims 12 wins, while the i5-14600T takes 5. The average benchmark score confirms the Arc G3 EXTREME's overall edge: 36699 against 32707, a difference of roughly 12%. The Arc G3 EXTREME also sits in the 85th percentile of all CPUs, while the i5-14600T lands in the 83rd.

The largest single victory belongs to the Arc G3 EXTREME in Passmark's find prime numbers test, where it scores 248 against 121, a 105% advantage. This is the only head-to-head result that doubles the opponent's output. Extended instructions show a 41.4% lead (24017 versus 16985), and floating point math follows at 34.3% (86929 versus 64726). Data encryption favors the Arc G3 EXTREME by 31% (23881 versus 18226), and physics simulation shows the same 34.3% margin (2515 versus 1873). Passmark multithread gives the Arc G3 EXTREME a 16.1% lead (30659 versus 26409), while single-thread performance is 14.7% higher (4293 versus 3744).

The i5-14600T's wins are concentrated in Cinebench and integer work. The most decisive is Cinebench R23 single-core, where the i5-14600T scores 3169 against 1862, a 41.2% advantage. Cinebench R23 multi-core shows a 34.7% lead (22447 versus 14655). Cinebench R15 single-core goes to the i5-14600T by 16.3% (319 versus 267), and R15 multi-core by 3.1% (2262 versus 2192). Passmark integer math is the only non-Cinebench win for the i5-14600T, delivering 95112 versus 71164, a 25.2% margin.

The two Cinebench R20 results flip the pattern. The Arc G3 EXTREME wins R20 multi-core by 16.1% (10945 versus 9427) and R20 single-core by 16.2% (1545 versus 1330). This inconsistency between Cinebench versions is notable: the i5-14600T dominates R15 and R23, but loses R20 decisively. Passmark data compression is nearly even, with the Arc G3 EXTREME ahead by only 1.7% (307094 versus 301827).

Where Each One Wins

The Arc G3 EXTREME demonstrates a clear advantage in workloads that stress encryption, extended instruction sets, floating point math, and prime number generation. Its 31% lead in data encryption and 41.4% lead in extended instructions indicate strong SIMD and cryptographic throughput. The 34.3% margin in floating point math and the 105% margin in prime finding suggest that mathematical and scientific workloads favor the Arc G3 EXTREME substantially. The 16.1% lead in Passmark multithread, combined with the 14.7% single-thread advantage, shows consistent superiority in Passmark's general suite. Physics simulation, which often relies on floating point operations, also favors the Arc G3 EXTREME by 34.3%.

The i5-14600T wins where raw core count and high clock speeds matter most. Its boost clock of 5.10 GHz against the Arc G3 EXTREME's 4.70 GHz, combined with 20 threads against 14, explains the Cinebench R23 results. The 41.2% single-core lead in R23 and the 34.7% multi-core lead indicate that heavily threaded rendering workloads and lightly threaded tasks that scale with frequency both favor the i5-14600T. Passmark integer math, with a 25.2% lead, points to integer-heavy computation as another strength.

The split is not clean, however. Cinebench R20 contradicts the R15 and R23 pattern, giving the Arc G3 EXTREME wins in both single-core and multi-core. This suggests that the two processors respond differently to specific compiler optimizations and instruction scheduling across Cinebench versions. Data compression is effectively a tie, with only 1.7% separating the two.

Architecture Differences

The two processors differ fundamentally in platform design. The Intel Arc G3 EXTREME is a mobile processor on the Panther Lake architecture, built on a 3 nm process at Intel's foundry. It uses an Intel BGA 2540 socket and carries the part number SA4R3. The i5-14600T is a desktop part from the Raptor Lake Refresh generation, built on a 10 nm process, using Intel Socket 1700, with the part number SRN46. Its die size is 257 mm².

Core and thread counts differ despite both having 14 cores. The Arc G3 EXTREME has 14 threads (one per core), while the i5-14600T has 20 threads, meaning the i5-14600T supports Hyper-Threading on some of its cores. Base clocks are close: 1.90 GHz for the Arc G3 EXTREME versus 1.80 GHz for the i5-14600T. Boost clocks favor the i5-14600T at 5.10 GHz against 4.70 GHz. Thermal design power is lower on the Arc G3 EXTREME at 25 W, while the i5-14600T is rated at 35 W.

Cache hierarchies also differ. The Arc G3 EXTREME provides 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3. The i5-14600T offers 80 KB of L1 per core and 2 MB of L2 per core, but a larger 24 MB of shared L3. The larger per-core L1 and L2 on the Arc G3 EXTREME may contribute to its Passmark single-thread and encryption advantages, while the larger L3 on the i5-14600T helps in workloads that benefit from a bigger shared cache.

Memory support differs as well. The Arc G3 EXTREME supports LPDDR5X over a dual-channel bus with 136.5 GB/s of bandwidth. The i5-14600T supports both DDR4 and DDR5, also dual-channel, but its memory bandwidth is not recorded. The Arc G3 EXTREME does not support ECC memory, while the i5-14600T does. PCIe connectivity strongly favors the i5-14600T, which offers Gen 5 with 16 lanes (CPU only), versus the Arc G3 EXTREME's Gen 5 with 4 lanes (CPU only).

Integrated graphics differ by generation. The Arc G3 EXTREME uses Arc B390 graphics, while the i5-14600T uses UHD Graphics 770. Market segments match the physical design: the Arc G3 EXTREME is a mobile part, and the i5-14600T is a desktop part. Both are currently active in production. The i5-14600T has a recorded launch date of January 7, 2024, and a launch MSRP of $255. The Arc G3 EXTREME has a recorded release date of May 27, 2026, and no launch MSRP. Neither processor has an unlocked multiplier.

The Verdict

The data points to two distinct usage profiles. The Intel Arc G3 EXTREME is the stronger choice for workloads that involve encryption, extended instruction execution, floating point math, physics simulation, and prime number generation. Its 41.4% lead in extended instructions and 31% lead in data encryption make it the better fit for security-related and SIMD-heavy tasks. The 34.3% margins in floating point math and physics, plus the 105% lead in prime finding, indicate a processor tuned for mathematical throughput. Its 14.7% Passmark single-thread advantage and 16.1% Passmark multithread advantage reinforce an overall Passmark suite superiority.

The Intel Core i5-14600T is the better choice for Cinebench-style rendering workloads and integer math. Its 41.2% single-core and 34.7% multi-core leads in Cinebench R23 are substantial, and the 25.2% margin in Passmark integer math shows strength in integer-heavy computation. The higher 5.10 GHz boost clock and 20 threads give it a raw throughput advantage that Cinebench R23 reflects clearly. Its support for ECC memory and DDR4/DDR5 options, along with 16 PCIe Gen 5 lanes, makes it a more flexible desktop platform component.

The Cinebench R20 results complicate the picture. The Arc G3 EXTREME wins both R20 tests by about 16%, which contradicts the R15 and R23 outcomes. Any purchasing decision based on Cinebench should account for this version-specific behavior. The overall average benchmark score favors the Arc G3 EXTREME by roughly 12%, and it wins 12 of 17 head-to-head tests. The i5-14600T's wins are fewer but often larger in magnitude, particularly in R23. The Arc G3 EXTREME is a mobile part with a 25 W TDP and the i5-14600T is a desktop part with a 35 W TDP, so platform constraints will likely determine which processor is even usable in a given build. The recorded data supports the Arc G3 EXTREME for general and math-heavy workloads, and the i5-14600T for rendering and integer tasks.
