Intel Arc G3 vs Intel Core Ultra 7 258V Comparison

Intel's Arc G3 and Core Ultra 7 258V are both mobile processors on a 3 nm node, but they arrive in the database with very different amounts of measured evidence. The Arc G3 is a Panther Lake part with 14 cores, 14 threads, an 18 MB shared L3 cache, and no recorded benchmark scores. The Core Ultra 7 258V is a Lunar Lake part with 8 cores, 8 threads, a 12 MB shared L3 cache, a 74th percentile ranking, and an average benchmark score of 20454.

Head-to-Head Benchmarks

Direct comparison data is absent. The head-to-head benchmark list is empty, and the win counts are zero for both processors. The Arc G3 has no benchmark entries at all, so there is no measured score to place against any Core Ultra 7 258V result. The 258V, by contrast, has a full set of Cinebench, Geekbench, and PassMark results. The recorded scores are listed below.

| Test | Score |

|---|---|

| Cinebench R15 multicore | 1596.5 |

| Cinebench R15 singlecore | 285 |

| Cinebench R20 multicore | 6739 |

| Cinebench R20 singlecore | 951 |

| Cinebench R23 multicore | 10301 |

| Cinebench R23 singlecore | 1872 |

| Geekbench multicore | 9325 |

| Geekbench singlecore | 2100 |

| PassMark data compression | 176686 |

| PassMark data encryption | 13534 |

| PassMark extended instructions | 14717 |

| PassMark find prime numbers | 185 |

| PassMark floating point math | 57372 |

| PassMark integer math | 42889 |

| PassMark multithread | 18887 |

| PassMark physics | 1565 |

| PassMark random string sorting | 21580 |

| PassMark single thread | 4018 |

| PassMark singlethread | 4018 |

Within the PassMark data, the compression score of 176686 is the largest recorded value, while find prime numbers at 185 is the smallest. Floating point math at 57372 is above integer math at 42889, and multithread at 18887 is well above single-thread at 4018. The PassMark single-thread figure appears twice in the recorded data at 4018. These workload-specific measurements exist only for the 258V; the Arc G3 has no equivalent entries.

Because the 258V is the only measured chip, its nearest rivals provide the only external benchmark context. Its average score of 20454 is 0.1% below the AMD Ryzen 5 5600's 20468, 0.1% above the AMD Ryzen 5 8500G's 20425, 0.2% above the AMD EPYC 9454P's 20422, and 0.4% above the AMD EPYC 7713's 20363. The nearest rival list for the 258V contains two Ryzen 5 models and two EPYC models, all within 0.4% of its average score. The Arc G3 has no nearest rivals listed, so no equivalent comparison exists for it.

FAQ

Q: Which processor has more cores and threads?

A: The Arc G3 has 14 cores and 14 threads. The Core Ultra 7 258V has 8 cores and 8 threads. Both processors list equal core and thread counts.

Q: What are the process node and foundry differences?

A: Both chips use a 3 nm process. The Arc G3 is fabricated by Intel, while the Core Ultra 7 258V is fabricated by TSMC.

Q: How does the cache hierarchy compare?

A: Both use 192 KB of L1 cache per core and 2.5 MB of L2 cache per core. The shared L3 cache is 18 MB on the Arc G3 and 12 MB on the Core Ultra 7 258V.

Q: What integrated graphics are listed?

A: The Arc G3 lists Arc B370 graphics. The Core Ultra 7 258V lists Arc 140V graphics.

Q: What measured performance does the Core Ultra 7 258V show?

A: It records Cinebench R23 multicore 10301 and single-core 1872, Geekbench multicore 9325 and single-core 2100, PassMark multithread 18887, single-thread 4018, integer math 42889, floating point math 57372, data compression 176686, data encryption 13534, extended instructions 14717, physics 1565, random string sorting 21580, and find prime numbers 185. The Arc G3 records no benchmark scores.

Q: What are the clock speeds and TDPs?

A: The Arc G3 has a 1.90 GHz base clock, a 4.60 GHz boost clock, and a 25 W TDP. The Core Ultra 7 258V has a 2.20 GHz base clock, a 4.80 GHz boost clock, and a 17 W TDP.

Architecture Differences

The two processors share a 3 nm manufacturing process but split on foundry and design. The Arc G3 belongs to the Panther Lake generation. Its architecture field is not listed. The Core Ultra 7 258V belongs to the Lunar Lake architecture and the Core Ultra Series 2 family. The 258V is listed under the Core Ultra Series 2 family, while the Arc G3 has no series entry. The Arc G3 uses 14 cores and 14 threads; the 258V uses 8 cores and 8 threads.

Cache design is common at the first two levels: 192 KB L1 per core and 2.5 MB L2 per core. The L3 cache is not shared equally: 18 MB on the Arc G3 versus 12 MB on the 258V. Memory and I/O features are identical: LPDDR5X support, dual-channel memory bus, 136.5 GB/s bandwidth, and Gen 5 PCIe with 4 CPU lanes. ECC memory is not supported on either part.

Graphics and socket assignments differ. The Arc G3 carries Arc B370 graphics and uses Intel BGA 2540. The 258V carries Arc 140V graphics and uses Intel BGA 2833. The sockets are different, so the two are not interchangeable on a board. The Arc G3's release date of 2026-05-27 is later than the 258V's 2024-09-23.

Power and clock behavior also differ. The Arc G3 has a 25 W TDP, a 1.90 GHz base clock, and a 4.60 GHz boost clock. The 258V has a 17 W TDP, a 2.20 GHz base clock, and a 4.80 GHz boost clock. The 258V's higher base and boost clocks give it the clock advantage in the recorded specifications. The Arc G3's higher TDP and larger L3 cache are the counterpoints. Both are mobile, active production parts with locked multipliers.

The Verdict

The recorded data is one-sided. The Core Ultra 7 258V has an extensive benchmark record, a 74th percentile rank, and an average score of 20454. The Arc G3 has no benchmark record, an average score of 0, and a 50th percentile listing. The 258V's nearest rivals are all AMD parts within 0.4% of its average score, which gives it a stable measured position. The Arc G3's specification advantages are real: 14 cores versus 8, 18 MB shared L3 versus 12 MB, and a larger 25 W TDP envelope. But no recorded score translates those specifications into performance.

The data supports the 258V for any workload where measured scores matter. The Arc G3 remains a specification-only entry. It has more cores, more threads, more L3 cache, and a later release date, but the database contains no Cinebench, Geekbench, or PassMark results for it. A selection based on benchmark evidence has only one candidate: the Core Ultra 7 258V.
