Intel Arc G3 vs Intel Core Ultra 5 250KF Plus Comparison

Where Each One Wins

The benchmark data splits these two Intel processors into completely different market segments, and the recorded results reflect that distinction clearly. The Intel Arc G3 is a mobile processor built for the Panther Lake platform, while the Intel Core Ultra 5 250KF Plus is a desktop part from the Arrow Lake Refresh family. The database contains no benchmark scores for the Arc G3, which means every measurable performance data point in this comparison belongs to the Core Ultra 5 250KF Plus.

For the Core Ultra 5 250KF Plus, the strongest results appear in multi-threaded workloads. Cinebench R23 multicore returns a score of 42,718, while Cinebench R20 multicore reaches 17,941 and Cinebench R15 multicore lands at 4,305. The PassMark multithread test shows 50,146, with integer math at 123,030 and floating point math at 159,824. These numbers place the processor in the 93rd percentile among all CPUs in the database, with an average benchmark score of 66,159.

Single-threaded performance also shows strength. Cinebench R23 singlecore scores 6,030, Cinebench R20 singlecore reaches 2,532, and Cinebench R15 singlecore hits 607. PassMark single-thread returns 4,698. The data indicates that this desktop processor delivers balanced capability across both lightly threaded and heavily threaded applications.

The Arc G3 has no recorded benchmarks in the database. Its percentile ranking sits at 50, with an average benchmark score of zero. The absence of measurement data means the mobile processor cannot be directly compared on any performance metric. The wins column in the head-to-head comparison shows zero wins for the Arc G3 and zero for the Core Ultra 5 250KF Plus, because no head-to-head benchmarks exist in the database.

Architecture Differences

The two processors diverge sharply on architectural fundamentals. The Arc G3 uses the Panther Lake codename and is manufactured on a 3 nm process by Intel's own foundry. It packs 14 cores and 14 threads, with no hyper-threading. Base clock sits at 1.90 GHz, boosting to 4.60 GHz. The thermal design power is 25 watts, reflecting its mobile positioning. The socket is Intel BGA 2540, a ball-grid array design for soldered installation.

The Core Ultra 5 250KF Plus belongs to the Core Ultra Series 2 family with the Arrow Lake Refresh codename. It also uses a 3 nm process, but the foundry is TSMC rather than Intel. The chip contains 18 cores and 18 threads. Base clock is 4.20 GHz, boosting to 5.30 GHz. Thermal design power is 125 watts, five times higher than the mobile part. It uses Intel Socket 1851 and has an unlocked multiplier for overclocking.

Cache hierarchies differ notably. Both processors share 192 KB of L1 cache per core. The Arc G3 has 2.5 MB of L2 cache per core and 18 MB of shared L3 cache. The Core Ultra 5 250KF Plus has 3 MB of L2 per core and 30 MB of shared L3. The larger L3 on the desktop part represents a 66% increase in shared cache capacity.

Memory support separates the two as well. The Arc G3 uses LPDDR5X memory in a dual-channel configuration, delivering 136.5 GB/s of bandwidth. The Core Ultra 5 250KF Plus uses DDR5 memory, also dual-channel, with 115.2 GB/s bandwidth. The mobile part actually has higher memory bandwidth, but the desktop part supports ECC memory while the mobile part does not.

PCI Express connectivity shows a major gap. The Arc G3 provides Gen 5 with only 4 lanes for the CPU. The Core Ultra 5 250KF Plus provides Gen 5 with 20 lanes. The desktop processor offers five times the PCIe lane count, which matters for discrete GPU connectivity and expansion.

Integrated graphics also differ completely. The Arc G3 includes Arc B370 integrated graphics. The Core Ultra 5 250KF Plus has no integrated graphics at all, indicated as N/A in the database. Transistor count and die size are recorded only for the desktop part: 17,800 million transistors on a 243 mm² die. The mobile processor has no listed transistor count or die size.

Release timing shows the mobile part arriving later. The Core Ultra 5 250KF Plus released on March 10, 2026. The Arc G3 released on May 27, 2026. Both processors are listed as active production parts.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. Every benchmark score belongs exclusively to the Core Ultra 5 250KF Plus. The Arc G3 has zero recorded scores across all test categories.

For the Core Ultra 5 250KF Plus, the largest single result is PassMark data compression at 553,155. Data encryption reaches 41,292, and extended instructions score 42,880. Random string sorting returns 67,209. Prime number finding returns 452, which is the lowest score in the set. Physics simulation returns 3,183.

The Cinebench suite shows progression across versions. Cinebench R15 multicore scores 4,305, R20 multicore scores 17,941, and R23 multicore scores 42,718. The scaling from R15 to R23 reflects workload intensification across versions. Single-core results follow a similar pattern: 607 in R15, 2,532 in R20, and 6,030 in R23.

Comparing against nearest rivals in the database, the Core Ultra 5 250KF Plus sits within a tight cluster. The Intel Core 9 273PQE has an average score of 66,099, which is 0.1% higher. The AMD Ryzen 9 7950X3D scores 65,914, 0.4% higher. The Intel Core Ultra 5 250K Plus scores 66,855, which is 1% higher than the 250KF Plus. The AMD EPYC 4465P scores 66,925, also 1.1% higher.

These delta values indicate that the Core Ultra 5 250KF Plus performs nearly identically to its closest competitors. The spread from the lowest rival to the highest rival is only 1.5 percentage points. This positions the processor in a very competitive performance band where small differences in workload characteristics could flip the ranking.

The average benchmark score of 66,159 places the processor in the 93rd percentile among all CPUs. That percentile rank indicates that approximately 93% of processors in the database score lower on the aggregate benchmark metric.

The Verdict

The data supports a clear segmentation between these two processors. The Intel Core Ultra 5 250KF Plus is the only one with measurable performance data. Its 18 cores, 5.30 GHz boost clock, and 30 MB of L3 cache deliver strong multi-threaded and single-threaded results. The Cinebench R23 multicore score of 42,718 and single-core score of 6,030 demonstrate capability across both workload types.

The Arc G3 cannot be evaluated on performance because the database contains no benchmark results for it. Its specifications indicate a mobile-focused design: 14 cores, 25 watt TDP, LPDDR5X memory, and integrated Arc B370 graphics. The 4 PCIe Gen 5 lanes and BGA 2540 socket reinforce the mobile positioning.

For desktop computing tasks that require sustained multi-core throughput, the Core Ultra 5 250KF Plus is the processor with recorded evidence. Its 93rd percentile ranking and average benchmark score of 66,159 confirm strong standing among all CPUs. The unlocked multiplier allows overclocking, and the 20 PCIe Gen 5 lanes support high-bandwidth expansion.

For mobile or low-power applications, the Arc G3 offers a different feature set with its integrated graphics and 25 watt TDP, but no performance data exists to validate its capabilities. The choice between these two processors depends entirely on the intended usage context, and the database only provides measurement data for the desktop part.

The nearest rival comparisons show that the Core Ultra 5 250KF Plus holds its own within a 1.1 percentage point margin of four other processors. The Intel Core Ultra 5 250K Plus scores 1% higher, while the AMD EPYC 4465P scores 1.1% higher. These are marginal differences, not decisive gaps.
