Intel Core Ultra 7 265KF vs Intel Core Ultra X7 368H Comparison

The Verdict

The benchmark database shows a decisive performance hierarchy between these two processors. The Intel Core Ultra 7 265KF wins all 17 recorded head-to-head comparisons, with no benchmark favoring the Intel Core Ultra X7 368H. The average benchmark score for the 265KF is 71910, placing it in the 94th percentile of all CPUs, while the 368H averages 40518, sitting in the 87th percentile. The 265KF is a desktop part with a 125 W TDP and unlocked multiplier, while the 368H is a mobile part with a 25 W TDP and locked multiplier. Buyers seeking maximum compute throughput should select the 265KF; the 368H serves scenarios where the integrated Arc B390 graphics and lower power envelope take priority.

Architecture Differences

The two processors come from different Intel lineups and foundries. The Core Ultra 7 265KF belongs to the Core Ultra Series 2, uses the Arrow Lake-S architecture, and is fabricated on a 3 nm process by TSMC. The Core Ultra X7 368H belongs to the Core Ultra Series 3, uses the Panther Lake-H architecture, and is fabricated on a 3 nm process by Intel's own foundry. The 265KF has 20 cores and 20 threads, while the 368H has 16 cores and 16 threads; neither part uses simultaneous multithreading. The 265KF carries a transistor count of 17,800 million on a 243 mm² die, while the 368H has no recorded transistor or die size data.

Cache layouts differ. Both parts have 192 KB of L1 per core, but the 265KF provides 3 MB of L2 per core versus 2.5 MB per core on the 368H. The shared L3 cache on the 265KF is 30 MB, while the 368H has only 18 MB. The 265KF supports DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth; the 368H supports LPDDR5X on a dual-channel bus with 153.6 GB/s bandwidth. Neither processor supports ECC memory. The 265KF exposes 20 PCIe Gen 5 lanes from the CPU, while the 368H exposes only 4 PCIe Gen 5 lanes. The 265KF has no integrated graphics, while the 368H includes Arc B390 graphics. The 265KF uses an Intel Socket 1851 and is a desktop part; the 368H uses an Intel BGA 2540 socket and is a mobile part.

Head-to-Head Benchmarks

The 265KF dominates every measured workload, but the magnitude varies across tests. In Cinebench R23 multicore, the 265KF scores 49736 against 28221 for the 368H, a 76.2% advantage. The single-core result in the same test shows 7021 versus 3984, also a 76.2% gap. Cinebench R20 multicore follows the same pattern: 20889 versus 11852, with a 76.2% delta. Cinebench R15 multicore shows 5013 versus 2844, a 76.3% lead. The consistent 76% margins across all Cinebench versions indicate a uniform architectural advantage in both multi-threaded and single-threaded rendering workloads.

The PassMark suite reveals where the gap narrows and where it widens. The smallest delta appears in PassMark single-thread tests: the 265KF scores 4928 against 4005 for the 368H, a 23% lead. PassMark physics shows a 27.2% gap (3633 versus 2857). These modest single-thread margins suggest the 368H's Panther Lake cores are competitive on a per-clock basis, but the 265KF's higher boost clock of 5.50 GHz versus 5.00 GHz helps it pull ahead.

The largest deltas appear in data-heavy workloads. PassMark data compression shows 666589 for the 265KF versus 312927 for the 368H, a 113% lead. PassMark extended instructions shows 54513 versus 25669, a 112.4% gap. PassMark random string sorting shows 79735 versus 38093, a 109.3% advantage. These results indicate the 265KF's larger L3 cache (30 MB versus 18 MB) and higher core count provide outsized benefits for memory-intensive and instruction-heavy tasks.

Other PassMark tests show substantial but smaller margins. Data encryption: 48198 versus 25228, a 91% lead. Floating point math: 189431 versus 105681, a 79.2% gap. Multithread: 58518 versus 32956, a 77.6% lead. Integer math: 143351 versus 88083, a 62.7% gap. Find prime numbers: 486 versus 321, a 51.4% lead. The 265KF wins every category, but the 368H's closest results (single-thread and physics) indicate it is not completely outclassed in lightly threaded scenarios.

The base clock difference is stark: 3.90 GHz versus 2.00 GHz. This reflects the 368H's mobile design, where power efficiency matters more than sustained frequency. The 265KF's boosted clock reaches 5.50 GHz, while the 368H tops out at 5.00 GHz. The 368H compensates with higher memory bandwidth (153.6 GB/s versus 102.4 GB/s) because LPDDR5X offers a wider effective data path in mobile configurations. The 265KF's 20 PCIe Gen 5 lanes support discrete graphics and NVMe storage, whereas the 368H's 4 lanes are suited for thin-and-light laptops with integrated graphics. The 368H's release date is later, and it carries an Arc B390 iGPU, which the desktop part lacks entirely.
