Its single-thread PassMark scores (4005 vs 3947) show a 1.4% lead.

Architecture Differences

The architectural contrast is stark. The Intel Core i7-14700HX uses the Raptor Lake architecture on a 10 nm process, while the Intel Core Ultra X7 368H uses the Panther Lake architecture on a 3 nm process. Both are manufactured by Intel. The i7-14700HX has 20 cores and 28 threads, whereas the Ultra X7 has 16 cores and 16 threads, meaning it lacks hyper-threading.

Cache configurations differ significantly. The i7-14700HX has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and a large 33 MB shared L3 cache. The Ultra X7 has a much larger 192 KB L1 cache per core and 2.5 MB of L2 per core, but a smaller 18 MB shared L3. The die size for the i7-14700HX is recorded at 257 mm², while no die size is listed for the Ultra X7.

Memory support is another major divider. The i7-14700HX supports DDR4 and DDR5 memory in a dual-channel configuration and includes ECC support. The Ultra X7 supports only LPDDR5X memory in a dual-channel configuration, with a recorded memory bandwidth of 153.6 GB/s, and does not support ECC. The i7-14700HX offers PCIe Gen 5 with 16 lanes (CPU only), while the Ultra X7 offers PCIe Gen 5 with only 4 lanes (CPU only). Integrated graphics also differ: the i7-14700HX uses UHD Graphics 770, while the Ultra X7 uses Arc B390.

The base and boost clocks tell a similar story. The i7-14700HX has a base clock of 2.10 GHz and boosts to 5.50 GHz. The Ultra X7 has a base clock of 2.00 GHz and boosts to 5.00 GHz. The i7-14700HX has an unlocked multiplier, while the Ultra X7 is locked. The i7-14700HX has a recorded TDP of 55, while the Ultra X7 has a TDP of 25. The sockets are different: Intel BGA 1964 for the i7-14700HX and Intel BGA 2540 for the Ultra X7. The release dates are also distinct, with the i7-14700HX released in 2024 and the Ultra X7 in 2026.

The Verdict

The data indicates that the Intel Core i7-14700HX is the stronger choice for multi-threaded, throughput-heavy workloads. Its 49.1% lead in integer math and 40.1% lead in data compression are decisive. The 34% advantage in Cinebench R15 multicore and 10.2% in Cinebench R20 multicore reinforce this. Users running parallel tasks such as compilation, data processing, or content creation that scales across many threads will see clear benefits from the i7-14700HX. It also offers flexibility with DDR4/DDR5 memory support and ECC, plus more PCIe lanes.

The Intel Core Ultra X7 368H is the better option for single-thread performance and efficiency. Its 47.2% lead in Cinebench R23 singlecore and 26.2% lead in Cinebench R15 singlecore show a substantial per-core advantage. The 48.6% win in PassMark find prime numbers and 21.2% win in PassMark physics indicate strong raw computational speed per thread. Its 12.8% win in Cinebench R23 multicore is notable, suggesting that in some modern multi-threaded tests, the newer architecture compensates for fewer cores. With a TDP of 25 versus 55, the Ultra X7 is designed for lower power draw, which suits thinner laptops and longer battery life. The 153.6 GB/s memory bandwidth is a specific advantage for memory-intensive tasks.
