Intel Core Ultra X7 368H vs Intel Xeon 6507P Comparison

The Intel Core Ultra X7 368H and Intel Xeon 6507P are two very different processors that happen to land near each other in aggregate benchmark scores. The Core Ultra X7 368H is a 16-core mobile chip built for power efficiency, while the Xeon 6507P is an 8-core server processor with massive memory bandwidth and platform connectivity. The data shows the Core Ultra wins 12 of 17 head-to-head tests, but the Xeon takes the remaining 5, including some highly specialized workloads. Neither chip dominates the other outright; the right choice depends entirely on whether you prioritize raw compute versatility or specific server-oriented task throughput.

The Verdict

Pick the Intel Core Ultra X7 368H if you need a balanced, high-performance processor for mobile or general-purpose work. It leads in the vast majority of benchmarks, including all six Cinebench tests, with margins between 6.3% and 6.4% across the board. It also crushes the Xeon in floating-point math (51.8% ahead), prime number finding (43.3% ahead), and data encryption (42.1% ahead). With a 25W TDP versus the Xeon’s 150W TDP, the Core Ultra delivers superior compute efficiency for most tasks, making it the practical choice for laptops or compact systems.

Pick the Intel Xeon 6507P if your workload specifically benefits from its server-class architecture. It wins data compression by 12.1%, extended instructions by 6.3%, integer math by 0.9%, physics by 2.7%, and random string sorting by 4%. More importantly, it offers eight-channel DDR5 memory support with 409.6 GB/s bandwidth, ECC memory, and 88 PCIe Gen 5 lanes — features the Core Ultra simply cannot match. The Xeon is for workstation and server builds where memory capacity, reliability, and I/O expansion matter more than peak single-thread or multi-thread speed.

The aggregate scores are nearly identical — the Core Ultra averages 40518 versus the Xeon’s 40426, a difference of just 0.2%. Both sit at the 87th percentile of all CPUs. The Xeon’s launch MSRP is $765. The Core Ultra has no listed launch MSRP. If you have to choose based purely on benchmark wins, the Core Ultra is the stronger all-rounder. If you need a server platform, the Xeon’s platform features outweigh its benchmark losses.

Where Each One Wins

The Core Ultra X7 368H wins decisively in every rendering and single-threaded test. In Cinebench R15, R20, and R23, it beats the Xeon by roughly 6.3% in both multi-core and single-core runs. Its single-thread advantage is most pronounced in PassMark, where it scores 4005 versus 3643 — a 9.9% lead. This makes the Core Ultra the better choice for applications that rely on per-core performance, such as lightly threaded productivity apps, web browsing, and legacy software that doesn’t scale across many cores.

The Core Ultra also dominates math-heavy and security-related workloads. Floating-point math shows a massive 51.8% advantage (105681 vs 69604), and prime number finding is 43.3% faster (321 vs 224). Data encryption is 42.1% faster (25228 vs 17753), which is notable for anyone handling encrypted files or secure connections. These results point to a processor with well-balanced execution units that excel at both integer and floating-point operations.

The Xeon 6507P wins where its larger L3 cache and higher memory bandwidth come into play. Data compression is its biggest victory, scoring 356190 versus 312927 — a 12.1% lead. This is a classic workload that benefits from large caches and fast memory access. Extended instructions are 6.3% faster (27385 vs 25669), suggesting the Xeon’s instruction set extensions handle certain SIMD or specialized operations more efficiently. Random string sorting is 4% faster, integer math is nearly tied at 0.9% faster, and physics is 2.7% faster. These are niche wins, but they matter for specific server-side tasks like database indexing, compression algorithms, and scientific computing.

Architecture Differences

The two chips come from entirely different Intel architectures and fabrication nodes. The Core Ultra X7 368H uses the Panther Lake architecture on Intel’s 3 nm process, while the Xeon 6507P uses Granite Rapids on a 5 nm process. The Core Ultra is part of the Core Ultra Series 3 (Panther Lake-H) mobile family, whereas the Xeon belongs to the Xeon 6 (Granite Rapids-SP) server line.

Core counts differ significantly. The Core Ultra has 16 cores and 16 threads, meaning no hyperthreading. The Xeon has 8 cores but 16 threads, relying on simultaneous multithreading to reach the same thread count. This explains why the Core Ultra leads in most multi-threaded tests despite having a lower base clock — it has twice the physical cores. The Core Ultra’s base clock is 2.00 GHz with a 5.00 GHz boost, while the Xeon runs at 3.50 GHz base and 4.30 GHz boost.

Cache configurations are also starkly different. The Core Ultra has 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. The Xeon has 112 KB L1 per core, 2 MB L2 per core, but a much larger 48 MB shared L3. The Xeon’s 48 MB L3 is likely a major factor in its compression and extended instruction wins, as more data can reside on-chip. Memory support is a critical divergence: the Core Ultra uses LPDDR5X with dual-channel memory and 153.6 GB/s bandwidth, while the Xeon uses DDR5 with eight-channel memory and 409.6 GB/s bandwidth. ECC memory is supported only on the Xeon.

PCIe lanes are another major difference. The Core Ultra offers just 4 PCIe Gen 5 lanes, which is typical for a mobile chip. The Xeon provides 88 PCIe Gen 5 lanes, enabling massive expansion for GPUs, NVMe storage, and network cards. The Core Ultra includes integrated Arc B390 graphics; the Xeon has no integrated graphics. Sockets differ as well: the Core Ultra uses Intel BGA 2540 (soldered), while the Xeon uses Intel Socket 4710 (likely LGA for server boards).

Head-to-Head Benchmarks

The most lopsided win for the Core Ultra X7 368H is in PassMark floating-point math, where it scores 105681 against the Xeon’s 69604 — a 51.8% advantage. This is a massive gap that indicates the Core Ultra’s FPU throughput is far superior, likely due to its 16 physical cores and newer 3 nm architecture. Similarly, PassMark find prime numbers shows a 43.3% lead for the Core Ultra (321 vs 224), and data encryption is 42.1% faster (25228 vs 17753). These three wins alone make the Core Ultra a clear choice for scientific computing, cryptography, and any workload with heavy arithmetic.

In Cinebench tests, the Core Ultra wins all six by a consistent 6.3% to 6.4% margin. For example, Cinebench R15 multi-core is 2844 vs 2676, R20 multi-core is 11852 vs 11150, and R23 multi-core is 28221 vs 26548. Single-core results follow the same pattern: R15 at 401 vs 377, R20 at 1673 vs 1573, and R23 at 3984 vs 3747. The consistency suggests a fundamental per-core performance advantage for the Core Ultra, not just a core-count benefit.

The Xeon 6507P’s biggest win is data compression, where it scores 356190 versus 312927, a 12.1% margin. This is notable because compression typically benefits from large caches and high memory bandwidth — both of which favor the Xeon. Extended instructions follow with a 6.3% win (27385 vs 25669), and random string sorting is 4% faster (39682 vs 38093). The Xeon also edges out the Core Ultra in physics (2935 vs 2857, 2.7%) and integer math (88877 vs 88083, 0.9%). PassMark multithread is the closest overall test, with the Core Ultra winning 32956 vs 31233, a 5.5% margin.
