Intel Core i5-14500 vs Intel Core Ultra 5 245T Comparison

The Intel Core Ultra 5 245T is the clear performance leader in this comparison, winning 13 of 17 head-to-head benchmarks against the Intel Core i5-14500. Its most dramatic advantage appears in Cinebench R23, where it nearly doubles the i5-14500’s multi-core score and delivers a 48.2% single-core lead. However, the i5-14500 is not without its own victories, particularly in integer-heavy and data-compression workloads, where it posts wins of 21.9% and 30.8% respectively. The data reveals two distinctly different processors: the Ultra 5 245T is built for raw compute throughput and modern instruction efficiency, while the i5-14500 retains an edge in specific legacy and memory-bound tasks.

Head-to-Head Benchmarks

The single most striking result is in Cinebench R23 multi-core, where the Core Ultra 5 245T scores 26208 versus the i5-14500’s 15012. That is a 42.7% delta, a massive gap that dwarfs the near-ties seen in other multi-threaded tests. For context, in Cinebench R20 multi-core the difference shrinks to just 0.2% (11007 vs 10985), and in Passmark multithread it is again only 0.2% (30833 vs 30777). The R23 result suggests the Ultra 5 245T’s architecture scales far better under sustained modern rendering workloads, even though both CPUs have 14 cores. The i5-14500’s 20 threads versus the Ultra 5 245T’s 14 threads do not help in R23, where the newer chip’s efficiency per core dominates.

Single-core performance tells a similarly lopsided story. In Cinebench R23 single-core, the Ultra 5 245T scores 3699 against 1917 for the i5-14500, a 48.2% advantage. Cinebench R15 single-core shows a 26.6% lead (372 vs 273), while R20 single-core is nearly identical (1553 vs 1550, a 0.2% delta). Passmark single-thread also favors the Ultra 5 245T at 4367 versus 3952, a 9.5% win. The only single-core test where the i5-14500 comes close is R20, indicating that the Ultra 5 245T’s higher boost clock of 5.10 GHz versus 5.00 GHz, combined with its newer architecture, translates into consistently superior per-thread execution.

The i5-14500 fights back in Passmark’s memory and integer benchmarks. Data compression is its biggest win: 371294 versus 283812, a 30.8% margin. Integer math follows at 108124 versus 88676, a 21.9% lead. Random string sorting also goes to the i5-14500 by 17.3% (40980 vs 34931). These results point to the i5-14500’s legacy Raptor Lake design excelling in workloads that rely on high memory throughput and branch-heavy integer operations, likely benefiting from its DDR4 support and mature memory controller. Extended instructions is a narrow i5-14500 win at 22473 versus 22071, a 1.8% margin.

The Ultra 5 245T dominates the remaining math and physics tests. Floating-point math shows a 26.7% advantage (108499 vs 79576), and physics is 23.4% ahead (2278 vs 1746). Prime number finding is the most extreme outlier: the Ultra 5 245T scores 324 versus 106, a 67.3% blowout that suggests a fundamentally more efficient integer pipeline for iterative algorithms. Data encryption also favors the Ultra 5 245T by 9.3% (23656 vs 21457). Notably, the two CPUs are virtually tied in Passmark multithread (0.2% delta) and Cinebench R20 multi-core (0.2% delta), meaning the Ultra 5 245T’s overall win count is driven by single-core and specialized math tests rather than broad multi-threaded parity.

The Verdict

The data is unambiguous: the Intel Core Ultra 5 245T is the superior processor for most computing tasks, with 13 wins out of 17 benchmarks and a 48.2% single-core lead in Cinebench R23. Anyone prioritizing modern rendering, floating-point math, physics simulations, or single-threaded responsiveness should choose the Ultra 5 245T. Its 5.10 GHz boost clock and 3 nm TSMC process node deliver efficiency that the i5-14500’s 10 nm Intel process cannot match, as evidenced by the 67.3% prime-number advantage and 26.7% floating-point win.

The Intel Core i5-14500 is the pick only for a narrow set of workloads. Its 30.8% data-compression win and 21.9% integer-math victory suggest it retains an edge in database-style operations, file archiving, and legacy integer-heavy applications. The 17.3% random-string-sorting win reinforces this pattern. For users running such workloads on a Socket 1700 platform with DDR4 memory, the i5-14500 offers a compelling reason to stay with the older architecture. However, the overall average benchmark scores are nearly identical — 38531 for the i5-14500 versus 38194 for the Ultra 5 245T — and both sit at the 86th percentile of all CPUs, meaning neither is a slouch. The verdict is simple: go with the Ultra 5 245T unless your specific software is dominated by the i5-14500’s compression and integer strengths.

Specification Differences

The two processors differ across almost every major specification. The i5-14500 uses Intel Socket 1700, while the Ultra 5 245T requires Intel Socket 1851. The i5-14500 has 20 threads from its 14 cores, whereas the Ultra 5 245T has only 14 threads, matching its core count. Base clocks differ at 2.60 GHz for the i5-14500 versus 2.20 GHz for the Ultra 5 245T, but boost clocks reverse the order: 5.00 GHz versus 5.10 GHz. Both have a 65 W TDP.

Memory support is a major divergence: the i5-14500 supports both DDR4 and DDR5, while the Ultra 5 245T supports only DDR5. The Ultra 5 245T also specifies a memory bandwidth of 102.4 GB/s, a figure not listed for the i5-14500. PCIe lanes differ, with the i5-14500 offering Gen 5 with 16 lanes (CPU only) and the Ultra 5 245T offering Gen 5 with 20 lanes (CPU only). Integrated graphics are also distinct: the i5-14500 features UHD Graphics 770, while the Ultra 5 245T ships with Arc Xe-LPG Graphics 64EU. The launch MSRP for the i5-14500 is $232, and for the Ultra 5 245T it is $270. Both are active desktop parts with no unlocked multiplier.

Architecture Differences

The architectural gap is foundational. The i5-14500 is built on Intel’s Raptor Lake architecture (codename Raptor Lake-R) using a 10 nm process at Intel’s foundry, while the Ultra 5 245T uses Arrow Lake (codename Arrow Lake-S) on a 3 nm process fabricated by TSMC. The Ultra 5 245T has 17,800 million transistors on a 243 mm² die, whereas the i5-14500’s die size is 215 mm² with no transistor count listed. Cache hierarchies differ substantially: the i5-14500 has 80 KB of L1 per core and 1.25 MB of L2 per core, while the Ultra 5 245T has 192 KB of L1 per core and 3 MB of L2 per core. Both share 24 MB of L3 cache.

The thread count difference stems from the i5-14500’s support for Hyper-Threading, giving 20 threads from 14 cores, whereas the Ultra 5 245T has no such feature, yielding 14 threads. The Ultra 5 245T’s larger L1 and L2 caches per core explain its dominance in single-threaded and math-heavy benchmarks, as seen in the 67.3% prime-number win and 26.7% floating-point advantage. The i5-14500’s smaller caches and older process do not hinder its data-compression performance, however, suggesting its memory controller and DDR4 compatibility provide a compensating advantage. Both CPUs support ECC memory and are produced by Intel, but the foundry shift to TSMC for the Ultra 5 245T is a defining architectural change.

Where Each One Wins

The Intel Core Ultra 5 245T is the clear winner for compute-intensive and modern workloads. It excels in rendering, as shown by its 42.7% Cinebench R23 multi-core lead, and in single-threaded tasks, with a 48.2% R23 single-core advantage. Physics simulations, floating-point math, and prime-number calculations all favor the Ultra 5 245T by margins between 23.4% and 67.3%. Data encryption is also its domain, with a 9.3% win. This makes it the ideal choice for 3D modeling, scientific computing, and any software that leverages AVX-512-style instruction sets or relies on high per-core IPC. Its 5.10 GHz boost clock and 3 nm process node are the key enablers.

The Intel Core i5-14500 wins in a more specialized set of scenarios. Its 30.8% data-compression victory and 21.9% integer-math lead make it the better option for file archiving, database indexing, and legacy enterprise applications that are integer-bound. Random string sorting, with a 17.3% win, points to strengths in sorting algorithms and text processing. Extended instructions, though a narrow 1.8% win, suggests the i5-14500 retains some relevance in niche instruction-heavy code. For users on a Socket 1700 platform with DDR4 memory, the i5-14500’s compatibility is a practical advantage, and its 20 threads provide better multi-tasking in thread-scaled legacy software. In every other measurable category, the data favors the Ultra 5 245T.
