Intel Core i5-9500 vs Intel Core Ultra 3 105UL Comparison

The Intel Core i5-9500 and the Intel Core Ultra 3 105UL represent two very different design philosophies, separated by nearly six years of silicon evolution. The data shows a decisive 14-to-3 win in head-to-head tests for the newer Core Ultra 3, but the specific workloads where the older i5-9500 wins reveal that this is not a simple generational sweep. The verdict is nuanced: the Core Ultra 3 105UL is the superior all-around processor for modern multithreaded and single-threaded tasks, while the i5-9500 retains a clear edge in a few specialized data-processing and instruction-heavy workloads. Both chips sit at the 68th percentile of all CPUs, indicating they are firmly in the mid-range tier, but their paths to that position are entirely different.

The Verdict

The Intel Core Ultra 3 105UL is the pick for anyone running contemporary applications that scale across cores or benefit from high per-thread performance. Benchmark results show it leads the i5-9500 in every Cinebench iteration, from a 12.1% advantage in Cinebench R15 single-core to an 11.9% lead in Cinebench R23 multi-core. It also dominates in PassMark’s integer math (41,171 vs 27,574, a 33% lead) and floating-point math (30,750 vs 23,788, a 22.6% lead). For general productivity, video encoding, or any workload that is not specifically optimized for the i5-9500’s legacy architecture, the Core Ultra 3 is the clear choice.

The Intel Core i5-9500, however, is not obsolete. It wins decisively in PassMark data compression (136,283 vs 93,961, a 45% lead) and extended instructions (12,088 vs 5,634, a 114.6% lead), and it also takes random string sorting (16,894 vs 11,179, a 51.1% lead). This makes it the better option for specialized scientific computing, legacy software that relies on older x86 instruction sets, or database-style workloads dominated by data compression and sorting. If your primary application is one of these specific tasks, the i5-9500’s performance advantage is substantial enough to justify its older platform.

Architecture Differences

The two processors are built on fundamentally different foundations. The i5-9500 uses Intel’s Coffee Lake architecture on a 14 nm process node, while the Core Ultra 3 105UL is based on the Meteor Lake architecture on a 7 nm node. This process shrink is a major factor in the Core Ultra 3’s efficiency and performance characteristics. The i5-9500 is a 6-core, 6-thread part with a base clock of 3.00 GHz and a boost of 4.30 GHz, drawing 65W TDP. The Core Ultra 3 105UL has 8 cores and 10 threads, with a much lower 1.50 GHz base clock and a 4.20 GHz boost, but its TDP is just 15W — a dramatic efficiency improvement.

Cache configurations also differ significantly. The i5-9500 has 64 KB of L1 and 256 KB of L2 per core, with 9 MB of shared L3. The Core Ultra 3 105UL features larger per-core caches: 112 KB of L1 and 2 MB of L2 per core, plus 10 MB of shared L3. Memory support is a key differentiator: the i5-9500 is limited to DDR4 with a dual-channel bus and 42.7 GB/s of bandwidth, while the Core Ultra 3 supports DDR5 (capacity depends on motherboard) and offers 89.6 GB/s of bandwidth on the same dual-channel configuration. This more than doubles the theoretical memory bandwidth, which contributes to the Core Ultra 3’s lead in memory-sensitive benchmarks.

Platform support and integrated graphics also differ. The i5-9500 uses the Intel Socket 1151 and PCIe Gen 3 with 16 CPU lanes, while the Core Ultra 3 105UL uses the newer Socket 1851 with PCIe Gen 4 and 8 CPU lanes. The i5-9500 integrates UHD 630 graphics, whereas the Core Ultra 3 features the more capable Arc Xe-LPG 48EU. The i5-9500 is end-of-life and was released in 2018; the Core Ultra 3 105UL is active and launched in 2024 with a launch MSRP of $295. Neither chip has an unlocked multiplier.

Head-to-Head Benchmarks

The Core Ultra 3 105UL wins every Cinebench test, and the margins are remarkably consistent. In Cinebench R15 multi-core, it scores 881 against the i5-9500’s 776, an 11.9% lead. The single-core R15 result is 124 vs 109, a 12.1% gap. This pattern holds in R20 (3,671 vs 3,236 multi-core; 518 vs 456 single-core) and R23 (8,742 vs 7,705 multi-core; 1,234 vs 1,087 single-core). The consistency of these deltas — all between 11.8% and 12.1% — suggests a uniform architectural advantage rather than a workload-specific quirk.

PassMark results paint a more complex picture. The Core Ultra 3 wins data encryption by a wide margin: 6,354 vs 3,125, a 50.8% lead. It also takes find prime numbers (44 vs 36), floating-point math (30,750 vs 23,788, a 22.6% lead), integer math (41,171 vs 27,574, a 33% lead), multithread (10,285 vs 9,826, a 4.5% lead), physics (718 vs 619, a 13.8% lead), and single-thread (3,382 vs 2,565, a 24.2% lead). The single-thread result is particularly telling: the Core Ultra 3’s higher per-core performance, despite a lower base clock, shows the IPC gains of the newer architecture.

The i5-9500’s three wins are substantial. Its data compression score of 136,283 dwarfs the Core Ultra 3’s 93,961 — a 45% advantage. The extended instructions test is even more lopsided: 12,088 vs 5,634, a 114.6% lead. Random string sorting goes to the i5-9500 at 16,894 vs 11,179, a 51.1% edge. These are not marginal victories; they indicate that for specific workloads, the older chip’s design remains highly competitive.

Where Each One Wins

The Intel Core Ultra 3 105UL is the winner for virtually all modern general-purpose computing. Its advantages in single-thread performance (24.2% in PassMark), integer math (33%), floating-point math (22.6%), and data encryption (50.8%) make it the better choice for office productivity, web browsing, software development, photo editing, and most gaming scenarios that rely on strong per-core performance. Its 8-core, 10-thread configuration and superior memory bandwidth also give it an edge in content creation tasks like video rendering, as shown by its consistent Cinebench R23 multi-core lead of 11.9%.

The Intel Core i5-9500 is the specialist’s choice. Its 45% lead in data compression makes it the better option for file archiving, backup software, and database compression workloads. The massive 114.6% advantage in extended instructions suggests it is far superior for scientific computing or legacy applications that use older x86 instruction sets. The 51.1% win in random string sorting also points to strengths in certain text-processing or data-wrangling tasks. For users running these specific applications, the i5-9500’s performance is worth the trade-off of higher power consumption and an older platform.

The efficiency story is one-sided. The Core Ultra 3 105UL delivers higher performance across most tests while consuming just 15W TDP compared to the i5-9500’s 65W. This makes the newer chip the clear winner for compact desktop builds or systems where heat and power draw are primary concerns. The i5-9500’s 14 nm node and older design cannot match this efficiency, even if its raw performance in specialized tasks remains impressive.
