Intel Core i5-14490F vs Intel Core Ultra 7 258V Comparison

Head-to-Head Benchmarks

The benchmark data records a decisive overall win for the Intel Core i5-14490F, which takes 14 of the 17 shared tests. The Intel Core Ultra 7 258V wins only 3 tests, and two of those are the same PassMark single-thread measurement recorded under two different labels.

The largest margin appears in Cinebench R23 multi-core, where the i5-14490F scores 23000 versus 10301 for the Ultra 7 258V, a 123.3% advantage. This is the single biggest gap in the entire comparison. Cinebench R20 multi-core shows a similar pattern: 9660 against 6739, a 43.3% lead. The i5-14490F also dominates in PassMark integer math, scoring 87844 versus 42889, a 104.8% difference. Data compression is another strong area, with 340026 versus 176686 for a 92.4% lead.

The i5-14490F wins single-core tests as well, though by smaller margins. In Cinebench R15 single-core it scores 327 against 285, a 14.7% edge. Cinebench R20 single-core shows 1363 versus 951, a 43.3% difference. Cinebench R23 single-core has 3247 versus 1872, a 73.5% gap. The Ultra 7 258V does take the PassMark single-thread test, scoring 4018 versus 3873, a 3.6% edge. That is the only single-threaded win for the Ultra 7, and it is a narrow one.

The Ultra 7 258V also wins the PassMark find prime numbers test, scoring 185 against 122, a 34.1% advantage. This is a notable result because it is the only multi-core workload where the Ultra 7 comes out ahead by a significant amount. The i5-14490F still leads in floating point math, 66558 versus 57372, a 16% gap, and in extended instructions, 21731 versus 14717, a 47.7% difference.

Other wins for the i5-14490F include PassMark multi-thread (28662 versus 18887, 51.8%), random string sorting (35608 versus 21580, 65%), physics (2093 versus 1565, 33.7%), and data encryption (18225 versus 13534, 34.7%). The overall average benchmark score reflects the same hierarchy: 38149 for the i5-14490F against 20454 for the Ultra 7 258V. The i5-14490F sits at the 86th percentile of all CPUs in the database, while the Ultra 7 258V sits at the 74th percentile. Its nearest rivals in the database include the Intel Core Ultra 5 245T and AMD Ryzen 7 250, both within 0.2% of its average score, while the Ultra 7 258V sits close to the AMD Ryzen 5 5600 and AMD Ryzen 5 8500G.

Architecture Differences

These two processors come from different Intel generations and target different market segments. The i5-14490F is a desktop part from the Core 14th Gen series, built on Raptor Lake architecture with a 10 nm process node from Intel's own foundry. The Ultra 7 258V is a mobile part from Core Ultra Series 2, built on Lunar Lake architecture with a 3 nm process node from TSMC.

The core counts differ substantially. The i5-14490F has 10 cores and 16 threads, while the Ultra 7 258V has 8 cores and 8 threads. The i5-14490F therefore supports simultaneous multithreading, whereas the Ultra 7 258V does not. This explains much of the multi-core performance gap. The i5-14490F also has a larger L3 cache at 24 MB shared, compared to 12 MB shared for the Ultra 7 258V. Per-core cache allocations differ as well: the i5-14490F has 80 KB of L1 per core and 1.25 MB of L2 per core, while the Ultra 7 258V has 192 KB of L1 per core and 2.5 MB of L2 per core. The Ultra 7 has more cache per core, but fewer cores overall.

Clock speeds favor the i5-14490F in terms of raw boost capability. Its base clock is 2.50 GHz with a boost of 5.00 GHz. The Ultra 7 258V has a base clock of 2.20 GHz and a boost of 4.80 GHz. That difference, combined with the thread count advantage, gives the i5-14490F a strong lead in sustained multi-threaded workloads.

Power and platform characteristics diverge sharply. The i5-14490F has a 65 W TDP and uses Intel Socket 1700. The Ultra 7 258V has a 17 W TDP and uses Intel BGA 2833, which is a soldered mobile socket. Memory support also differs: the i5-14490F supports DDR4 and DDR5 in dual-channel configuration, while the Ultra 7 258V supports only LPDDR5X, also dual-channel, with a recorded memory bandwidth of 136.5 GB/s. The i5-14490F does not have a listed memory bandwidth figure in the database.

PCIe lane counts are another point of separation. The i5-14490F provides Gen 5 with 16 lanes from the CPU only. The Ultra 7 258V provides Gen 5 with 4 lanes from the CPU only. Integrated graphics differ as well: the i5-14490F has no integrated graphics, while the Ultra 7 258V includes Arc 140V graphics.

Release dates place these parts in different windows. The i5-14490F was released at the end of 2023, and the Ultra 7 258V was released in September 2024. Both are marked as active in production. Neither has a launch MSRP listed in the database, and neither has an unlocked multiplier.

The Verdict

The data points to two very different products for two very different purposes. The Intel Core i5-14490F is a desktop processor with substantially higher raw compute throughput. It wins 14 of 17 head-to-head tests and holds a 86.4% higher average benchmark score. Its multi-core lead is enormous, especially in Cinebench R23 where it more than doubles the Ultra 7 258V's score. Single-core performance also favors the i5-14490F in most tests, with the only exception being a 3.6% PassMark single-thread edge for the Ultra 7 258V.

The Intel Core Ultra 7 258V is a mobile processor with a much lower TDP of 17 W versus 65 W. It has fewer cores and threads, a smaller L3 cache, and a lower boost clock. Its wins are limited to find prime numbers and the PassMark single-thread test. It does have a much smaller process node, 3 nm versus 10 nm, and it includes integrated graphics, which the i5-14490F lacks. It also supports only LPDDR5X memory, while the i5-14490F supports DDR4 and DDR5.

For users who need maximum compute performance in desktop workloads, the i5-14490F is the clear choice. For users who need a low-power mobile processor with integrated graphics, the Ultra 7 258V is the only option that fits that form factor. The two are not direct competitors despite sharing the Intel brand. The benchmark results confirm that the i5-14490F is the stronger CPU in nearly every measurable compute task, but the Ultra 7 258V is the more efficient part with a much lower power envelope.

The percentile rankings reinforce this split. The i5-14490F sits at the 86th percentile of all CPUs in the database, while the Ultra 7 258V sits at the 74th percentile. The i5-14490F's nearest rivals include the Intel Core i5-13600KF and AMD Ryzen 7 250, all within 0.2% of its average score. The Ultra 7 258V's nearest rivals include the AMD Ryzen 5 5600 and AMD Ryzen 5 8500G, also within 0.2%. This places the Ultra 7 258V in a much lower performance tier.

Where Each One Wins

The Intel Core i5-14490F wins in every Cinebench test, both single-core and multi-core. It also wins in PassMark data compression, data encryption, extended instructions, floating point math, integer math, multi-thread, physics, and random string sorting. Its largest margins are in Cinebench R23 multi-core (123.3%), PassMark integer math (104.8%), and PassMark data compression (92.4%). These are all heavily multi-threaded workloads that take advantage of its 10 cores and 16 threads.

The Intel Core Ultra 7 258V wins in only two distinct tests: PassMark find prime numbers and PassMark single-thread. The find prime numbers result is notable because it is a 34.1% advantage, the largest win for the Ultra 7 in the entire comparison. This suggests the Ultra 7's per-core architecture handles that specific workload better. The PassMark single-thread win is narrow at 3.6%, but it does indicate that the Ultra 7 is competitive in lightly threaded tasks despite its lower boost clock.

The i5-14490F is the better choice for productivity workloads, compilation, rendering, and any task that scales with core count. The Ultra 7 258V is the better choice for low-power mobile systems where integrated graphics are required and where the find prime numbers workload matters. For general desktop use, the data clearly favors the i5-14490F. For battery-conscious mobile use, the Ultra 7 258V has the efficiency advantage, though it sacrifices a large amount of multi-core performance to get there.
