Intel Core i9-11950H vs Intel Xeon E-2436 Comparison

The Intel Xeon E-2436 and Intel Core i9-11950H occupy opposite ends of the Intel spectrum: one is a Raptor Lake-based server/workstation part on Socket 1700, the other a Tiger Lake-H mobile chip on BGA 1787. Despite the i9’s higher core count, the Xeon E-2436 wins 13 of the 17 head-to-head benchmark comparisons, with a higher average benchmark score of 28,530 versus 28,332. Both chips sit at the 80th percentile among all CPUs, but their performance profiles diverge sharply across specific workloads.

Head-to-Head Benchmarks

The most dramatic gap appears in PassMark’s physics test, where the Xeon E-2436 scores 1,353 against the i9-11950H’s 1,013 — a 33.6% advantage. This is the largest delta in either direction and suggests the Xeon’s architecture handles physics simulation with far greater efficiency. Floating-point math also favors the Xeon decisively: 50,198 versus 44,137, a 13.7% lead. Single-thread performance tells a similar story — the Xeon posts 3,575 in PassMark single-thread versus 3,141 for the i9, a 13.8% edge, and it wins every Cinebench single-core round (R15: 261 vs 245, +6.5%; R20: 1,090 vs 1,024, +6.4%; R23: 2,596 vs 2,439, +6.4%).

Multi-core Cinebench results are consistent but less lopsided: the Xeon leads by 6.4% across R15 (1,853 vs 1,741), R20 (7,723 vs 7,257), and R23 (18,389 vs 17,279). PassMark multithread shows a narrower 3.9% win for the Xeon (21,708 vs 20,900). Data encryption is another clear Xeon win: 13,920 vs 12,658, a 10% margin. Data compression is nearly a tie, with the Xeon at 246,902 and the i9 at 246,195 — just 0.3% apart.

The i9-11950H fights back in four tests. Its biggest win is integer math: 74,649 versus 67,082, a 10.1% advantage for the i9. Prime number finding also goes to the i9 (93 vs 84, +9.7%). Random string sorting favors the i9 by 3.4% (29,375 vs 28,363), and extended instructions see the i9 edge ahead by a hair: 16,361 vs 16,334, a 0.2% margin. These wins cluster around integer-heavy and sorting workloads, where the i9’s extra two cores and 16 threads likely compensate for its lower per-core clock advantage.

Notably, the Xeon’s wins are not just more numerous but also larger in magnitude. Its average winning margin across all victories is roughly 10.3%, while the i9’s average winning margin is about 5.9%. The Xeon’s physics and floating-point dominance suggests its Raptor Lake architecture delivers better execution unit utilization, while the i9’s Tiger Lake design excels at integer throughput despite its lower base clock of 2.10 GHz versus the Xeon’s 2.90 GHz.

The Verdict

For server and workstation deployments, the Intel Xeon E-2436 is the clear choice based on benchmark data. It wins 13 of 17 comparisons, including all Cinebench tests, all single-thread tests, physics, floating-point math, encryption, and multithread. Its physics lead of 33.6% and floating-point lead of 13.7% are exactly the kinds of margins that matter for simulation, scientific computing, and financial modeling workloads. The Xeon also supports ECC memory, which the i9 does not, and uses DDR5 with 76.8 GB/s bandwidth versus the i9’s DDR4 at 51.2 GB/s — a 50% theoretical memory bandwidth advantage that shows up in data-heavy tasks.

The Intel Core i9-11950H is a different animal: a mobile part with a 35 W TDP versus the Xeon’s 65 W, designed for laptops and compact systems. Its 8 cores and 16 threads give it a raw integer math advantage of 10.1% over the Xeon, and it wins prime number finding and random string sorting by 9.7% and 3.4%, respectively. If your workload is integer-heavy — think database indexing, compression algorithms, or certain cryptographic operations — the i9’s extra cores deliver measurable gains. It also includes integrated UHD Graphics 750, which the Xeon lacks entirely, making it a viable option for systems that need display output without a discrete GPU.

However, the i9’s end-of-life production status and mobile socket (BGA 1787) mean it is not a drop-in upgrade path. The Xeon E-2436 remains active on Socket 1700, offering a longer procurement horizon. For anyone building a new system today, the data overwhelmingly favors the Xeon unless the workload specifically requires integer-heavy throughput or integrated graphics. The i9’s launch MSRP was $556, while the Xeon’s launch MSRP is $331 — though price comparisons are secondary to the performance deltas shown here.

FAQ

Q: Which CPU wins more benchmark comparisons?

A: The Intel Xeon E-2436 wins 13 of 17 head-to-head tests, including all six Cinebench benchmarks and all single-thread tests. The Intel Core i9-11950H wins 4 tests: extended instructions, prime number finding, integer math, and random string sorting.

Q: How much faster is the Xeon in physics workloads?

A: The Xeon E-2436 scores 1,353 in PassMark physics versus 1,013 for the i9-11950H, a 33.6% advantage. This is the largest performance gap between the two CPUs in any benchmark.

Q: Does the i9 ever beat the Xeon by a wide margin?

A: Yes, in integer math the i9-11950H scores 74,649 versus 67,082 for the Xeon, a 10.1% lead. It also wins prime number finding by 9.7% (93 vs 84). These are its two largest victories.

Q: What memory types do these CPUs support?

A: The Xeon E-2436 supports DDR5 with dual-channel memory and 76.8 GB/s bandwidth, plus ECC memory. The i9-11950H supports DDR4 with dual-channel memory at 51.2 GB/s and has no ECC support.

Q: Are these CPUs in the same performance percentile?

A: Yes, both sit at the 80th percentile among all CPUs. The Xeon has an average benchmark score of 28,530, while the i9 averages 28,332 — a difference of about 0.7% in the Xeon’s favor.

Q: Does either CPU have integrated graphics?

A: Only the i9-11950H includes integrated graphics, specifically UHD Graphics 750. The Xeon E-2436 has no integrated graphics, so it requires a discrete GPU for display output.

Specification Differences

The two processors diverge in almost every physical specification. The Xeon E-2436 uses 6 cores and 12 threads, while the i9-11950H uses 8 cores and 16 threads. Base clocks differ significantly: the Xeon runs at 2.90 GHz, the i9 at 2.10 GHz, though both boost to 5.00 GHz. TDP is another major split — the Xeon draws 65 W, the i9 just 35 W. The Xeon uses Intel Socket 1700 (LGA), while the i9 uses Intel BGA 1787 (soldered). Cache sizes also differ: the Xeon has 18 MB of shared L3 cache, the i9 has 24 MB. Memory support separates them further — the Xeon uses DDR5 (dual-channel, 76.8 GB/s) with ECC; the i9 uses DDR4 (dual-channel, 51.2 GB/s) without ECC. PCIe generations and lane counts also differ: the Xeon offers Gen 5 with 16 CPU lanes, the i9 offers Gen 4 with 20 CPU lanes. The i9 includes integrated UHD Graphics 750; the Xeon has none. Production status diverges: the Xeon is active, the i9 is end-of-life. The Xeon’s launch MSRP is $331; the i9’s is $556. Part numbers are SRMXB for the Xeon and SRKT6 for the i9.

Architecture Differences

The Xeon E-2436 is built on Raptor Lake (specifically Raptor Lake-S) and belongs to the Xeon E-2400 series, released in December 2023. The i9-11950H uses Tiger Lake (Tiger Lake-H) from the Core 11th Gen series, released in May 2021. Both use a 10 nm process node from Intel, but they are fundamentally different designs. The Xeon’s die size is 163 mm², while the i9’s is 190 mm² — the larger die reflects the i9’s additional cores and integrated graphics. L1 and L2 caches are identical per core (80 KB L1, 1.25 MB L2), but the Xeon has 18 MB shared L3 versus 24 MB on the i9, which is consistent with the i9’s higher core count. The Xeon’s architecture targets server/workstation reliability with ECC memory support and DDR5, while the i9’s Tiger Lake-H targets mobile performance with integrated graphics and lower TDP. Neither chip has an unlocked multiplier, and both are fabricated by Intel. The Xeon’s memory bandwidth of 76.8 GB/s represents a 50% improvement over the i9’s 51.2 GB/s, a direct consequence of the newer DDR5 memory controller. The i9’s 20 PCIe Gen 4 lanes exceed the Xeon’s 16 Gen 5 lanes in count, but the Xeon’s Gen 5 standard offers higher per-lane bandwidth. The Xeon is the only one of the two with ECC support, a critical feature for data integrity in server environments. The i9’s integrated UHD Graphics 750 adds a display capability that the Xeon lacks, making the i9 a more self-contained mobile solution despite its older architecture.
