Intel Core i9-11900F vs Intel Xeon 6333P Comparison

Head-to-Head Benchmarks

The head-to-head comparison between the Intel Xeon 6333P and the Intel Core i9-11900F is overwhelmingly one-sided, but not entirely. Out of 17 recorded benchmark comparisons, the Core i9-11900F claims 13 wins, while the Xeon 6333P takes 4. The margin of victory, however, is highly asymmetrical.

The Core i9-11900F demonstrates its dominance in nearly every traditional compute workload. In the Cinebench suite, the results are consistent and decisive. The i9-11900F leads by 16.7% in Cinebench R15 multi-core (1890 vs. 1574), by 16.5% in single-core (266 vs. 222), and maintains a near-identical 16.7% edge in R20 multi-core (7878 vs. 6559). The pattern holds through R23, where the i9-11900F posts an 16.7% advantage in multi-core (18759 vs. 15617) and a 16.8% lead in single-core (2648 vs. 2204). These deltas indicate a consistent architectural performance gap that scales across all Cinebench versions.

The PassMark suite tells a similar story, but with even wider divergences. The i9-11900F is 28.8% faster in data compression (280847 vs. 199886), 19.1% ahead in data encryption (13636 vs. 11025), and 26.6% ahead in integer math (83718 vs. 61458). The single standout, non-Cinebench difference is in extended instructions, where the i9-11900F leads by a massive 32.9% (19443 vs. 13039). Random string sorting also goes heavily to the i9-11900F, with a 32.3% gap (32520 vs. 22010). Floating point math is closer, but the i9 still wins by 9.8% (48562 vs. 43801). The overall PassMark multithread score shows a 16.9% lead for the i9-11900F (22115 vs. 18374).

Yet the Xeon 6333P does not go winless, and its victories are notable. The most striking is in the PassMark find prime numbers test, where the Xeon 6333P scores 83 against the i9-11900F's 61, a 36.1% advantage. This is a rare case where the Xeon's architecture delivers a clear, large win. The physics test also goes to the Xeon 6333P by 39.1% (1320 vs. 949), showing a substantial lead in that specific simulation. Finally, the Xeon 6333P wins the single-thread PassMark test by a narrow 1.1% margin (3450 vs. 3413), a slim but real edge.

The overall picture in the head-to-head is that the Core i9-11900F is the far more capable general processor, but the Xeon 6333P has specialized strengths that should not be ignored. The data shows that the i9's wins are large and numerous, while the Xeon's wins are either very narrow (single-thread) or very specialized (prime numbers, physics). The 13-to-4 win split heavily favors the Core i9-11900F, but the Xeon's individual victories in physics and prime-number processing are notable.

Architecture Differences

The two processors come from entirely different design eras and market segments. The Intel Xeon 6333P is a server and workstation part based on the Raptor Lake architecture, specifically the Raptor Lake-R refresh, manufactured on a 10nm process. It is a 6-core, 12-thread processor with a base clock of 3.10 GHz and a boost clock of 5.20 GHz. Its die size is 163 mm². The Xeon 6333P supports DDR4 and DDR5 memory in a dual-channel configuration, includes ECC memory support, and offers PCIe Gen 5 with 16 CPU-only lanes. It targets the server and workstation market segment and remains in production.

The Intel Core i9-11900F is a desktop part, part of the Core 11th Gen family, built on the older Rocket Lake architecture and a 14nm process. It has 8 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 5.20 GHz. The die size is significantly larger at 276 mm². It only supports DDR4 memory in dual-channel mode, with a memory bandwidth listed at 51.2 GB/s. It does not support ECC. It offers PCIe Gen 4 with 20 lanes, which is more lanes than the Xeon, but on an older standard. The Core i9-11900F is a desktop processor and is marked as end-of-life.

The cache structures also differ. The Xeon 6333P has 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. The Core i9-11900F also has 80 KB of L1 per core, but only 512 KB of L2 per core, and 16 MB of shared L3. The Xeon's larger per-core L2 and shared L3 are potential contributors to its performance in specific workloads, despite having fewer cores.

The 14nm Rocket Lake process yields a much larger die (276 mm²) compared to the 10nm Raptor Lake refresh (163 mm²). The Core i9-11900F uses the older Intel Socket 1200, while the Xeon 6333P uses the newer Intel Socket 1700. The Xeon's memory support for DDR5 is a forward-looking feature that the Rocket Lake part cannot match. The Core i9-11900F was released in March 2021, while the Xeon 6333P is a much newer part, released in February 2025. The Xeon 6333P has an unlocked multiplier? No, the data shows the multiplier is locked for both parts.

Where Each One Wins

The Intel Core i9-11900F is the clear winner for most general-purpose and compute-heavy tasks. Its 8-core, 16-thread configuration gives it a decisive advantage in multi-threaded workloads like Cinebench rendering, data compression, encryption, and integer math. The data shows it is 16.7% ahead in R20 multi-core, 16.9% ahead in PassMark multithread, and 26.6% ahead in integer math. For users running video rendering, code compilation, data processing, or typical desktop productivity applications, the Core i9-11900F is the better choice. Its wins in single-core Cinebench benchmarks (16.5% to 16.8%) mean it also wins in everyday responsiveness and lightly-threaded applications. The Core i9-11900F also has a strong advantage in extended instructions (32.9%), which is relevant for workloads using AVX-512 or similar advanced instruction sets.

The Intel Xeon 6333P is the winner in two categories only, but they are consistent. The PassMark physics test and the prime-number finding test both are clear Xeon wins, by 39.1% and 36.1% respectively. These indicate a specific strength in certain types of integer-heavy, iterative calculations and physics simulations. The Xeon's single-thread PassMark score is also higher, but only by a 1.1% margin. For a server or workstation user who runs physics simulation or number-theoretic workloads, the Xeon 6333P is the better part, despite its lower core count. Its ECC memory support and DDR5 compatibility are also significant for reliability-focused server environments, though the benchmark scores do not reflect that directly. In contrast, the Core i9-11900F's desktop segment and end-of-life status make it a less future-proof option, but the data strongly favors it in raw performance.

The split is clear: the Core i9-11900F is the high-performance generalist, while the Xeon 6333P is the specialized or server-oriented alternative with specific physics and prime-number strengths, plus modern platform features. The average benchmark score for the Core i9 is 23254, while the Xeon's is 23823, but that overall average is heavily influenced by the Xeon's wins in the physics and prime tests, which do not offset the Core i9's dominance in breadth.
