Intel Core Ultra 7 366H vs Intel Xeon 6369P Comparison

The Verdict

The benchmark data splits these two Intel processors into distinct roles. The Intel Core Ultra 7 366H is the clear all-round winner, taking 13 of 17 head-to-head tests. Its most decisive victories come in encryption, physics calculations, and prime number finding, where it leads by 44.2%, 43.4%, and 131.2% respectively. This makes it the obvious choice for mobile users who need strong single-threaded responsiveness and heavy computational workloads without being tethered to a wall outlet.

The Intel Xeon 6369P, despite losing the overall benchmark count, has its own turf. It wins the Passmark single-thread test by 6.1% (4305 vs 4043) and dominates integer math by 17.1% (101013 vs 83695), plus data compression by 5.5% (346632 vs 327455). These are classic server-oriented strengths. For workloads that depend on raw integer throughput, compression, or high single-thread speed in a workstation context, the Xeon is the pick. The Xeon also brings ECC memory support, a feature the Ultra 7 lacks entirely, which matters for data integrity in server environments.

The database places both CPUs at the 87th percentile among all tested processors, meaning they sit at a similar overall performance tier. However, the Core Ultra 7 366H carries a higher average benchmark score of 41263 versus the Xeon's 40327, a margin of roughly 2.3%. The verdict is simple: the Ultra 7 366H is the better general-purpose processor, while the Xeon 6369P serves specialized server workloads and applications that rely on integer math and data compression. The Xeon does carry a launch MSRP of $606, but the data sheet does not list a launch price for the Ultra 7, so no direct price performance comparison can be made from these records.

Architecture Differences

The two chips could hardly be more different under the hood, and those differences explain the benchmark behavior. The Core Ultra 7 366H is built on Intel's 3 nm process node using the Panther Lake architecture, specifically the Panther Lake-H generation from the Core Ultra Series 3. It packs 16 cores and 16 threads, meaning it does not use Hyper-Threading. Each core has 192 KB of L1 cache and 2.5 MB of L2 cache, while the shared L3 cache totals 18 MB. The chip runs at a base clock of 2.00 GHz and boosts to 4.80 GHz. This is a mobile part, designed for the Intel BGA 2540 socket, with a thermal design power of just 25 watts. It supports DDR5 and LPDDR5X memory over a dual-channel bus, delivering 115.2 GB/s of bandwidth. It also includes integrated Intel Xe3 Graphics, making it a self-contained mobile solution. The CPU provides Gen 5 PCIe with 12 lanes.

The Xeon 6369P is a completely different animal. It uses the older but still active Raptor Lake architecture, specifically the Raptor Lake-R refresh from the Xeon 6 family. It has only 8 cores but 16 threads, so it does rely on Hyper-Threading. Its cache structure is smaller per core: only 80 KB of L1 and 2 MB of L2, but the shared L3 cache is larger at 24 MB. The Xeon runs a 3.30 GHz base clock and boosts much higher to 5.70 GHz. It is built on a 10 nm process node and has a die size of 257 mm². The socket is a desktop-style Intel Socket 1700, and the TDP is 95 watts, nearly four times that of the Ultra 7.

Memory support differs too. The Xeon supports both DDR4 and DDR5, but the database does not list a memory bandwidth figure. Critically, it supports ECC memory, which is standard for server reliability. The Ultra 7 does not support ECC. The Xeon also has more PCIe Gen 5 lanes: 16 versus 12. The Xeon has no integrated graphics, so it requires a discrete GPU, while the Ultra 7 offers integrated Intel Xe3e Graphics. The release dates also differ: the Ultra 7 is dated January 2026, the Xeon February 2025. The Xeon has a part number SRPLQ and the Ultra 7 SA4R9Q9EL, both with locked multipliers.

These architectural choices explain the benchmark patterns. The 3 nm mobile chip with 16 cores and a huge L1/L2 per core dominates in floating-point and physics work. The 10 nm Xeon, with fewer cores but a higher boost clock, still has enough per-thread power to win single-threaded tests in Passmark and outperform in integer math.

Head-to-Head Benchmarks

The Cinebench suite is a total sweep for the Core Ultra 7 366H. In Cinebench R23 multi-core, the Ultra 7 scores 28477 versus the Xeon's 25774, a 10.5% lead. Single-core R23 also goes to the Ultra 7 at 4020 against 3638, another 10.5% delta. The pattern repeats exactly in Cinebench R20: multi-core 11960 vs 10825 and single-core 1688 vs 1527, both 10.5% in favor of the Ultra 7. Cinebench R15 follows the same margin: 2870 vs 2598 multi-core and 405 vs 366 single-core, a 10.5% and 10.7% delta. These consistent margins show the Ultra 7's architecture is more efficient in the workload, likely due to the smaller process node and higher core count.

The Passmark suite breaks the pattern. The Xeon 6369P wins integer math by a decisive 17.1% (101013 vs 83695). It also wins data compression at 346632 vs 327455, a 5.5% delta, and single-thread performance at 4305 vs 4043, a 6.1% lead. The Xeon also wins the second single-thread listing (4305 vs 4043) which is the same test appearing twice in the records.

The Ultra 7 366H reclaims almost everything else in Passmark. The encryption test is a huge win: 25845 vs 17922, a 42.2% delta. Extended instructions go 26901 vs 22807, an 18% gain. Floating-point math goes 103615 vs 74151, a 39.7% lead. Physics is a 43.4% win (2880 vs 2008). Prime number finding is the biggest blowout at 131.2% (326 vs 141). The multi-thread Passmark test goes to the Ultra 7 by 10.3% (33429 vs 30315), and random string sorting goes 6.9% in its favor (39814 vs 37237).

This split is logical. The Xeon wins the integer-heavy and single-thread tests, while the Ultra 7 dominates in floating-point, encryption, physics, and anything that scales with its 16 cores. The Xeon's high boost clock of 5.70 GHz gives it the single-thread edge, but the Ultra 7's 16 cores and 3 nm process win most parallel loads.

Where Each One Wins

The data supports a clean split based on workload type and form factor.

Mobile compute and general CPU workloads go to the Ultra 7 366H. It wins every Cinebench test (R15, R20, R23) in both single and multi-core, with consistent 10.5% margins. It also wins the Passmark multithread test by 10.3% and has a 44.2% lead in encryption, a 39.7% lead in floating-point math, a 43.4% lead in physics, and a 131.2% lead in prime number finding. Any workload that is parallel, floating-point heavy, or encryption heavy will favor the Ultra 7. The 3 nm process and 16-core design make it the clear winner for rendering, simulation, and scientific computing. The integrated Xe3 Graphics also removes the need for a dedicated GPU in basic systems.

Server integer and compression workloads: The Xeon 6369P wins the Passmark integer math test by 17.1%, the data compression test by 5.5%, and the single-thread test by 6.1%. These are classic server/ workstation patterns. Integer math drives database operations, file systems, compression algorithms, and many business applications. The 24 MB L3 cache is larger, and the ECC memory support is a critical feature for servers that cannot tolerate data corruption. The Xeon also has a higher base clock (3.30 GHz) and boost clock (5.70 GHz), which helps in latency-sensitive, low-thread-count server jobs. The 95W TDP and Socket 1700 design fit a desktop workstation or rack server, not a laptop.

The verdict for buyers: Choose the Ultra 7 366H if you need a power-efficient, high-core-count mobile chip for varied work. The data shows it is faster in 13 of 17 tests, including all Cinebench suites and most Passmark math tests. Choose the Xeon 6369P if you need ECC memory, fast integer math, and single-thread performance in a workstation or server context. The Xeon's wins are fewer but concentrated in areas that matter for specific enterprise workloads. The database places both at the 87th percentile, but the Ultra 7's average score is higher at 41263 vs 40327, confirming that the Ultra 7 is the better general-purpose processor. The Xeon's strengths are real but narrow.
