Intel Core i5-1345UE vs Intel Core i5-9500F Comparison

The Intel Core i5-1345UE and Intel Core i5-9500F represent two very different interpretations of a mainstream processor: one is a low-power mobile part built for thin-and-light systems, the other a desktop chip designed for traditional towers. Benchmark data shows the newer mobile chip winning every single head-to-head test, though the margins reveal a more nuanced story about efficiency versus raw capability. The i5-1345UE records an average benchmark score of 2698, placing it in the 50th percentile of all CPUs, while the i5-9500F scores 2670, also in the 50th percentile. Despite the near-identical averages, the individual Cinebench runs show a consistent, if modest, advantage for the Raptor Lake part.

Head-to-Head Benchmarks

The i5-1345UE sweeps all six recorded Cinebench comparisons, with the largest wins coming in multi-threaded workloads. In Cinebench R23 multi-core, the mobile chip scores 9329 against the desktop’s 8453, a 10.4% advantage. That same 10.4% delta appears in Cinebench R20 multi-core, where the 1345UE posts 3918 versus 3550, and in Cinebench R15 multi-core, with scores of 940 and 852 respectively. The consistency of that 10.4% margin across three generations of Cinebench suggests a fundamental throughput advantage rather than a workload-specific quirk.

Single-core results follow the same pattern, though the gaps are slightly smaller. In Cinebench R23 single-core, the 1345UE scores 1317 against 1193, again a 10.4% lead. Cinebench R20 single-core shows 553 versus 501, also 10.4%. The narrowest margin appears in Cinebench R15 single-core, where the 1345UE’s 132 beats the 9500F’s 120 by 10%. The data shows that the 1345UE’s architectural advantages translate to both single-threaded responsiveness and multi-threaded rendering, with no test where the older desktop part manages to close the gap.

What is striking is that the 9500F, despite being a desktop chip with a 65W TDP and higher base clock of 3.00 GHz, cannot outperform a 15W mobile processor in any benchmark. The 1345UE’s boost clock of 4.60 GHz edges out the 9500F’s 4.40 GHz, and that 200 MHz difference, combined with two extra cores and six extra threads, appears decisive. The 9500F’s Geekbench results, which are not available for the 1345UE, show a single-core score of 1504 and multi-core of 5185, giving it a percentile ranking equal to the 1345UE despite the Cinebench losses. The average benchmark score tells a similar story: 2698 for the 1345UE versus 2670 for the 9500F, a difference of roughly 1%.

The Verdict

The data supports a clear choice for anyone prioritizing multi-threaded performance in a compact or battery-powered system: the Intel Core i5-1345UE wins every benchmark recorded, with multi-core leads of 10.4% across R15, R20, and R23. That consistency is remarkable given the 1345UE’s 15W TDP versus the 9500F’s 65W TDP. The mobile chip achieves its advantage with 10 cores and 12 threads, compared to the desktop’s 6 cores and 6 threads, and it does so while drawing far less power.

The i5-9500F, however, is not without rationale. It is a desktop Socket 1151 part with 16 PCIe Gen 3 lanes, compared to the 1345UE’s 8 Gen 4 lanes, making it the better fit for systems with multiple expansion cards or high-bandwidth storage. Its 42.7 GB/s memory bandwidth is explicitly listed, whereas the 1345UE’s bandwidth is not specified in the data. For users building a dedicated desktop rig with discrete graphics, the 9500F’s lack of integrated graphics is irrelevant, and its end-of-life status means it may be available at a different price point, though pricing is not part of this analysis.

The verdict hinges on use case. The 1345UE is the superior processor in raw compute terms, winning all six head-to-head tests and posting a higher average benchmark score. The 9500F makes sense only for those who need a desktop platform with PCIe Gen 3 lane count and are willing to accept lower Cinebench scores. For most workloads, the 1345UE’s 10.4% multi-core lead and 10% single-core lead make it the data-backed recommendation.

Architecture Differences

The two processors come from different architectural eras. The i5-1345UE is built on Raptor Lake, specifically the Raptor Lake-U mobile variant, fabricated on Intel’s 10 nm process. The i5-9500F uses the older Coffee Lake architecture, with a 14 nm process node. That process gap explains much of the efficiency difference: the 1345UE delivers higher performance at a fraction of the power draw, as evidenced by its 15W TDP versus the 9500F’s 65W.

Core counts differ significantly. The 1345UE has 10 cores and 12 threads, a configuration that includes efficiency cores to supplement performance cores. The 9500F has 6 cores and 6 threads, with no hyper-threading support. This explains the 1345UE’s 10.4% multi-core advantage, which is smaller than the core count difference might suggest, indicating that the 9500F’s higher base clock of 3.00 GHz helps it claw back some ground in sustained multi-threaded loads.

Cache hierarchies also differ. The 1345UE offers 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The 9500F has 64 KB L1 per core, 256 KB L2 per core, and 9 MB shared L3. The 1345UE’s larger per-core L2 cache is a notable architectural advantage, potentially improving hit rates for frequently accessed data.

Integrated graphics is another major split. The 1345UE includes Iris Xe Graphics with 80 execution units, making it self-sufficient for display output. The 9500F has no integrated graphics, requiring a discrete GPU for any video output. This is a fundamental design difference: the mobile chip targets all-in-one efficiency, while the desktop chip assumes a dedicated graphics card.

Memory support also differs. The 1345UE supports both DDR4 and DDR5, while the 9500F is limited to DDR4. Both use dual-channel memory buses, but the 1345UE’s broader compatibility offers a future-proofing advantage. The 9500F’s memory bandwidth is listed at 42.7 GB/s, a figure not provided for the 1345UE.

Specification Differences

The two processors differ across nearly every specification field. The 1345UE has 10 cores and 12 threads, versus 6 cores and 6 threads for the 9500F. Base clocks are dramatically different: 1400 MHz for the 1345UE against 3000 MHz for the 9500F. Boost clocks are closer, with the 1345UE at 4.60 GHz and the 9500F at 4.40 GHz. TDP is a major differentiator: 15W for the mobile chip versus 65W for the desktop chip.

Socket compatibility is entirely separate. The 1345UE uses Intel BGA 1744, a soldered mobile socket, while the 9500F uses Intel Socket 1151, a desktop LGA socket. The 1345UE supports PCIe Gen 4 with 8 CPU lanes; the 9500F supports PCIe Gen 3 with 16 CPU lanes. The 1345UE has integrated Iris Xe Graphics with 80 execution units; the 9500F has none.

Process node differs: 10 nm for Raptor Lake versus 14 nm for Coffee Lake. Memory support favors the 1345UE with both DDR4 and DDR5, while the 9500F only handles DDR4. The 9500F lists a memory bandwidth of 42.7 GB/s, a figure absent for the 1345UE. Cache configurations differ in every level: L1 is 80 KB per core versus 64 KB, L2 is 1.25 MB per core versus 256 KB, and L3 is 12 MB shared versus 9 MB shared.

Market segment and production status also diverge. The 1345UE is a mobile part, currently active in production. The 9500F is a desktop part, marked end-of-life. Release dates are far apart: the 1345UE launched in January 2023, while the 9500F launched in April 2019. Neither processor has a listed launch MSRP, and both have locked multipliers, preventing overclocking.
