Intel Core i5-14600KF vs Intel Core Ultra 5 245HX Comparison

The Intel Core i5-14600KF and the Intel Core Ultra 5 245HX are both 14-core processors that land in the 90th percentile of all CPUs, but they achieve that status through very different means. The i5-14600KF is a desktop part built for sustained multi-threaded workloads, winning 10 of the 17 head-to-head benchmarks, while the Ultra 5 245HX is a mobile chip that counters with superior single-thread performance, leading to a 7-win tally. The data reveals that the 14600KF is the choice for integer-heavy and compression tasks, while the 245HX excels in floating-point math, encryption, and prime-number finding, making the decision dependent on whether the workload favors raw throughput or specialized instruction efficiency.

Where Each One Wins

The benchmark results split cleanly along workload types. The Intel Core i5-14600KF dominates in Cinebench tests across the board, taking all six multicore and single-core variants with margins between 0.4% and 0.6%. It also wins decisively in PassMark’s integer math (36.7% ahead), data compression (23.4% ahead), and random string sorting (9.3% ahead). These are classic desktop productivity tasks that benefit from the processor’s higher boost clock of 5.30 GHz and its 20 threads, which allow more parallel work than the Ultra 5’s 14 threads. The 14600KF also edges out the 245HX in multithread performance (1.6% ahead), confirming its strength in heavily threaded applications.

The Intel Core Ultra 5 245HX, by contrast, wins where architectural efficiency matters more than raw thread count. Its biggest victories come in PassMark’s find prime numbers test, where it scores 359 versus 161 — a 55.2% lead — and in floating-point math, where it posts 120735 against 93048, a 22.9% advantage. It also takes data encryption (30022 vs 27608, an 8% lead), extended instructions (31212 vs 28785, a 7.8% lead), and physics (2526 vs 2449, a 3% lead). Most notably, the 245HX wins the PassMark single-thread test with 4481 versus 4273, a 4.6% margin, indicating that its Arrow Lake architecture delivers better per-core efficiency despite a lower 5.10 GHz boost clock. This makes the 245HX the better fit for scientific computing, cryptographic tasks, and single-threaded applications.

Head-to-Head Benchmarks

The head-to-head results show a pattern of close Cinebench scores followed by divergent PassMark outcomes. In Cinebench R15 multicore, the 14600KF scores 3280 against the 245HX’s 3261, a 0.6% edge. The single-core R15 result is tighter, with 462 versus 460, a 0.4% lead for the 14600KF. This trend continues through Cinebench R20 and R23, where the 14600KF wins both multicore (13668 vs 13590, and 32544 vs 32358) and single-core (1929 vs 1918, and 4594 vs 4568) by 0.6% in every case. These margins are small but consistent, showing that the desktop chip holds a slight clock-speed advantage across rendering workloads.

The PassMark suite tells a different story. The 14600KF’s biggest win is in integer math, where it scores 125982 against the 245HX’s 92150, a 36.7% margin. Data compression follows at 485140 versus 393071 (23.4% ahead), and random string sorting shows 52056 versus 47616 (9.3% ahead). The multithread test is closer, with 38697 versus 38069 (1.6% ahead). On the other side, the 245HX dominates in find prime numbers (359 vs 161, 55.2% ahead) and floating-point math (120735 vs 93048, 22.9% ahead). It also wins in data encryption (30022 vs 27608, 8% ahead), extended instructions (31212 vs 28785, 7.8% ahead), and physics (2526 vs 2449, 3% ahead). The single-thread PassMark test rounds out the 245HX’s wins with 4481 versus 4273, a 4.6% margin.

Specification Differences

The two processors differ most fundamentally in their sockets and market positioning. The 14600KF uses Intel Socket 1700 and is a desktop part, while the 245HX uses Intel BGA 2114 and is a mobile processor. The 14600KF has a 125 W TDP, whereas the 245HX is rated at 55 W, reflecting the mobile chip’s lower power envelope. Both have 14 cores, but the 14600KF offers 20 threads versus the 245HX’s 14, meaning the desktop chip supports simultaneous multi-threading. Clock speeds differ: the 14600KF runs at a 3.50 GHz base and 5.30 GHz boost, while the 245HX operates at 3.10 GHz base and 5.10 GHz boost.

Memory support diverges as well. The 14600KF supports both DDR4 and DDR5 in a dual-channel configuration, while the 245HX supports only DDR5. The 245HX also lists a memory bandwidth of 102.4 GB/s, a figure not provided for the 14600KF. The 245HX includes integrated graphics (Arc Xe-LPG Graphics 48EU), while the 14600KF has no integrated graphics. PCIe lanes differ, with the 14600KF offering Gen 5 with 16 CPU lanes and the 245HX offering Gen 5 with 20 CPU lanes. The 14600KF supports ECC memory, but the 245HX does not. Finally, the 14600KF has a launch MSRP of $294, while the 245HX has no listed launch MSRP.

Architecture Differences

The architectural split is stark. The 14600KF is built on Intel’s Raptor Lake architecture (Raptor Lake-R codename) using a 10 nm process node from Intel’s own foundry, with a die size of 257 mm². The 245HX uses the newer Arrow Lake architecture (Arrow Lake-HX codename) on a 3 nm process from TSMC, with a die size of 243 mm² and 17,800 million transistors. The cache hierarchies differ significantly: the 14600KF has 80 KB of L1 cache per core and 2 MB of L2 per core, while the 245HX has 192 KB of L1 per core and 3 MB of L2 per core. Both share 24 MB of L3 cache, but the larger per-core L1 and L2 caches on the 245HX likely contribute to its wins in single-thread and floating-point tests.

The 14600KF is a Raptor Lake Refresh part from the Core 14th Gen series, while the 245HX is a Core Ultra Series 2 part. The 245HX’s integrated Arc Xe-LPG Graphics 48EU is a notable feature absent from the 14600KF, which relies on a discrete GPU. The 245HX also has a higher transistor count (17,800 million) despite a smaller die, a result of the denser 3 nm process. Both chips have unlocked multipliers, but the 14600KF’s desktop socket and higher TDP suggest it is designed for overclocking and sustained high-power operation, whereas the 245HX’s mobile BGA socket and 55 W TDP prioritize efficiency in laptops.

The Verdict

The data points to a clear split: choose the Intel Core i5-14600KF for desktop workloads that benefit from higher thread counts and clock speeds. It wins every Cinebench test and dominates in integer math, data compression, and random string sorting, making it the superior choice for rendering, file compression, and general productivity. Its 20 threads and 5.30 GHz boost clock give it a measurable edge in multithreaded tasks, and its 90th percentile standing with an average score of 49394 places it just ahead of rivals like the AMD Ryzen 9 7900.

Choose the Intel Core Ultra 5 245HX for mobile computing or workloads that prioritize single-thread efficiency and specialized instruction handling. It wins the PassMark single-thread test by 4.6%, and its massive leads in find prime numbers (55.2%) and floating-point math (22.9%) make it the better option for scientific simulations, cryptography, and math-heavy applications. Its 55 W TDP and integrated graphics also make it suitable for thin-and-light laptops, while still hitting the 90th percentile with an average score of 48287. The 14600KF is the raw performance king for desktop builds, but the 245HX offers a more efficient, architecturally advanced package for mobile users who need targeted single-thread speed.
