Intel Core i5-14600KF vs Intel Core Ultra 5 235A Comparison

Head-to-Head Benchmarks

The head-to-head results split this pairing into two distinct performance profiles. The Intel Core Ultra 5 235A wins 12 of 17 recorded benchmarks, but the Intel Core i5-14600KF takes decisive victories in specific workloads. The most striking gap is in PassMark integer math, where the i5-14600KF scores 125,982 against the Ultra 5's 88,626, a 42.2% advantage. That is the single largest delta in the entire comparison. Data compression tells a similar story: the i5-14600KF posts 485,140 versus 393,800, a 23.2% lead.

The Ultra 5 235A counters with a dominating performance in PassMark find prime numbers, scoring 392 versus 161, a 58.9% advantage. This is the largest win for either side. Floating point math also favors the Ultra 5, 118,778 versus 93,048, a 21.7% gap. Extended instructions lean Ultra 5 as well, 31,625 against 28,785, a 9% difference. Data encryption adds another Ultra 5 win, 30,136 versus 27,608, an 8.4% margin.

The Cinebench suite is remarkably close. Across all six Cinebench tests, the Ultra 5 wins each time by a fraction of a percent. R15 multicore: 3,289 versus 3,280, a 0.3% edge. R15 singlecore: 464 versus 462, a 0.4% edge. R20 multicore: 13,705 versus 13,668, a 0.3% edge. R20 singlecore: 1,934 versus 1,929, a 0.3% edge. R23 multicore: 32,633 versus 32,544, a 0.3% edge. R23 singlecore: 4,607 versus 4,594, a 0.3% edge. These are statistical ties, effectively identical performance.

PassMark single-threaded tests show a clearer Ultra 5 advantage, 4,557 versus 4,273, a 6.2% lead. However, the i5-14600KF holds narrow wins in PassMark multithread (38,697 versus 38,392, a 0.8% edge), physics (2,449 versus 2,437, a 0.5% edge), and random string sorting (52,056 versus 49,489, a 5.2% edge). The overall benchmark averages reflect this split: the i5-14600KF has an average score of 49,394, while the Ultra 5 sits at 48,201. Both processors occupy the 90th percentile among all CPUs in the database.

Architecture Differences

The two processors represent different Intel designs. The i5-14600KF uses Raptor Lake architecture, specifically Raptor Lake-R, built on a 10 nm Intel process with a die size of 257 mm². The Ultra 5 235A uses Arrow Lake architecture, specifically Arrow Lake-S, built on a 3 nm TSMC process with a die size of 243 mm² and 17,800 million transistors. The smaller process node is a major architectural shift, though it does not automatically translate to superior performance across every test.

Core counts are identical: both have 14 cores. Thread counts differ, however. The i5-14600KF supports 20 threads, while the Ultra 5 235A supports 14 threads. This means the i5-14600KF has hyperthreading capability that the Ultra 5 lacks. Cache hierarchies also differ. The i5-14600KF has 80 KB L1 cache per core, 2 MB L2 cache per core, and 24 MB shared L3 cache. The Ultra 5 235A has 192 KB L1 cache per core, 3 MB L2 cache per core, and the same 24 MB shared L3 cache. The larger per-core caches on the Ultra 5 suggest a different caching strategy.

Clock speeds favor the i5-14600KF: a 3.50 GHz base clock and 5.30 GHz boost clock, versus 3.40 GHz base and 5.00 GHz boost on the Ultra 5. Power ratings diverge substantially, with the i5-14600KF rated at 125 W TDP and the Ultra 5 at 65 W TDP. The i5-14600KF supports DDR4 and DDR5 memory, while the Ultra 5 supports DDR5 only. The Ultra 5 has a documented memory bandwidth of 102.4 GB/s, while the i5-14600KF has no listed bandwidth figure. ECC memory is supported on the i5-14600KF but not on the Ultra 5.

PCIe lanes differ: the i5-14600KF offers Gen 5 with 16 CPU lanes, while the Ultra 5 offers Gen 5 with 20 CPU lanes. Sockets are incompatible, with the i5-14600KF on Intel Socket 1700 and the Ultra 5 on Intel Socket 1851. The Ultra 5 includes integrated Arc Xe-LPG Graphics with 24 EU, while the i5-14600KF has no integrated graphics. The i5-14600KF has an unlocked multiplier; the Ultra 5 does not. Release dates are roughly two years apart: October 2023 for the i5-14600KF, July 2025 for the Ultra 5.

Where Each One Wins

The i5-14600KF dominates integer-heavy and compression workloads. Its 42.2% lead in integer math makes it the clear choice for tasks that rely on integer arithmetic, such as certain types of data processing, scripting, or compression algorithms. The 23.2% advantage in data compression reinforces this profile. Random string sorting, a workload that often benefits from high per-thread throughput and cache, goes to the i5-14600KF by 5.2%. Multithread performance is essentially tied, with the i5-14600KF ahead by only 0.8%, and physics performance is similarly close at 0.5% ahead.

The Ultra 5 235A wins in floating-point and encryption-heavy tasks. Its 58.9% advantage in prime number finding is extraordinary and suggests a strong floating-point or specialized instruction pipeline. The 21.7% lead in floating-point math confirms this. Data encryption favors the Ultra 5 by 8.4%, and extended instruction workloads by 9%. Single-thread performance is also better on the Ultra 5, with a 6.2% lead in PassMark single-threaded tests.

For general productivity, the Cinebench results show no meaningful difference. The Ultra 5 wins every Cinebench test, but the margins are all under 0.5%, which is within measurement noise. The database effectively treats these as equal in rendering workloads. The i5-14600KF's higher thread count does not produce a Cinebench advantage, likely because the Ultra 5's higher single-thread efficiency compensates.

Specification Differences

The two processors differ on several key specification fields. The i5-14600KF has 20 threads, the Ultra 5 235A has 14. Base clock is 3.50 GHz versus 3.40 GHz. Boost clock is 5.30 GHz versus 5.00 GHz. TDP is 125 W versus 65 W. Process node is 10 nm (Intel) versus 3 nm (TSMC). Die size is 257 mm² versus 243 mm², with the Ultra 5 having 17,800 million transistors. L1 cache per core is 80 KB versus 192 KB. L2 cache per core is 2 MB versus 3 MB. L3 cache is identical at 24 MB shared.

Memory support differs: DDR4 and DDR5 on the i5-14600KF, DDR5 only on the Ultra 5. The Ultra 5 lists 102.4 GB/s memory bandwidth; the i5-14600KF has no bandwidth figure. ECC support is present on the i5-14600KF, absent on the Ultra 5. PCIe lanes are 16 versus 20, both Gen 5. Integrated graphics exist only on the Ultra 5 (Arc Xe-LPG Graphics 24EU). The multiplier is unlocked on the i5-14600KF, locked on the Ultra 5. Socket is 1700 versus 1851. Part numbers are SRN42 and SRWPN. The launch MSRP for the i5-14600KF is $294, and for the Ultra 5 235A it is $269.

The Verdict

The data draws a clear line. For integer-heavy, compression-focused, or multithreaded general workloads, the Intel Core i5-14600KF is the stronger choice. Its 42.2% integer math lead and 23.2% data compression advantage are decisive. The 20 threads and higher boost clock likely drive these results.

For floating-point, encryption, single-threaded, and specialized instruction workloads, the Intel Core Ultra 5 235A takes the win. The 58.9% prime number finding lead and 21.7% floating-point math advantage are substantial. The 3 nm TSMC process and larger per-core caches appear to deliver efficiency gains despite the lower TDP of 65 W.

Rendering performance is a dead heat. All Cinebench scores fall within 0.4% of each other, so neither processor offers a meaningful advantage there. The Ultra 5 235A's single-thread lead of 6.2% in PassMark suggests it will feel snappier in lightly threaded applications, while the i5-14600KF's multithread edge of 0.8% is too small to matter.

The i5-14600KF suits users with integer-heavy workloads, compression tasks, or those who want an unlocked multiplier and ECC support. The Ultra 5 235A suits users prioritizing floating-point math, encryption, single-thread performance, integrated graphics, or lower power consumption. The database shows both processors at the 90th percentile, so neither is weak. The choice depends entirely on workload profile.
