Intel Core i7-11850HE vs Intel Xeon W-2150B Comparison

The Intel Core i7-11850HE and Intel Xeon W-2150B represent two very different approaches to multi-threaded computing, separated by nearly four years of architectural evolution. The data shows a consistent, albeit narrow, victory for the mobile Tiger Lake-H part across every single benchmark in this comparison. The i7-11850HE wins all eight head-to-head tests, yet the margins are often razor-thin, particularly in Cinebench workloads. The most significant divergence appears in Geekbench single-core, where the newer architecture delivers a commanding lead. This is not a contest of raw core counts but a demonstration of IPC improvements and platform efficiency versus older, high-core-count workstation silicon.

Where Each One Wins

The Intel Core i7-11850HE takes the win in every measured category, but the nature of those wins varies dramatically by workload. In the Cinebench R15, R20, and R23 multi-core tests, the i7-11850HE edges out the Xeon W-2150B by a mere 0.2% in each case. For example, in Cinebench R23 multi-core, the i7-11850HE scores 17,402 against the Xeon's 17,368. This is a statistical tie, indicating that despite having two fewer cores and four fewer threads (8 cores/16 threads versus 10 cores/20 threads), the Tiger Lake part's higher per-core efficiency and superior memory subsystem compensate almost exactly for the Xeon's additional physical cores.

The single-core Cinebench results tell a similar story of marginal advantage. The i7-11850HE posts a 247 in Cinebench R15 single-core versus 246 for the Xeon, and a 2,456 versus 2,452 in R23 single-core. These 0.2% to 0.4% deltas are within run-to-run variance. Neither chip holds a meaningful advantage in single-threaded rendering tasks.

The decisive victory for the i7-11850HE comes in Geekbench. In the multi-core test, it scores 8,576 versus 8,481, a 1.1% advantage. However, the single-core Geekbench result is a blowout: the i7-11850HE scores 1,984 against the Xeon's 1,314, a staggering 51% delta. This is the clearest workload separation. The Xeon W-2150B, with its Skylake architecture and 14 nm process, simply cannot match the per-clock execution capabilities of the Tiger Lake-H design. For any application that is latency-sensitive or heavily dependent on single-threaded responsiveness, the i7-11850HE is categorically superior.

The Verdict

The benchmark results indicate that the Intel Core i7-11850HE is the better processor for the vast majority of use cases. It wins all eight head-to-head tests and does so while operating at a 35 W TDP, compared to the Xeon W-2150B's 120 W TDP. The i7-11850HE also brings modern platform features, including PCIe Gen 4 with 20 lanes and integrated UHD Graphics (Xe-LP), whereas the Xeon offers no integrated graphics and is limited to PCIe Gen 3 with 48 lanes.

The Xeon W-2150B's only theoretical advantages are its 10-core/20-thread configuration, quad-channel DDR4 memory support with 85.3 GB/s bandwidth, and ECC memory capability. However, the data shows these advantages do not translate into benchmark wins. The Xeon's 13.75 MB of shared L3 cache is dwarfed by the i7-11850HE's 24 MB shared L3, and the newer chip's 10 nm process node and Tiger Lake architecture overcome the core deficit.

For a mobile workstation or a compact, power-efficient system, the i7-11850HE is the clear choice. Its 51% Geekbench single-core lead and consistent multi-core parity, combined with integrated graphics and a fraction of the power draw, make it the superior all-around product. The Xeon W-2150B is end-of-life and only makes sense for a legacy workstation that requires ECC memory or a quad-channel memory bus, as those are the only features where it holds a hardware advantage. The data is unambiguous: the i7-11850HE is the faster CPU in every benchmark recorded.

Head-to-Head Benchmarks

The Geekbench single-core result is the single largest performance gap between these two processors. The i7-11850HE scores 1,984, while the Xeon W-2150B manages only 1,314. The 51% deltaPct is not a minor refinement; it represents a generational leap in architectural efficiency. This result strongly suggests that the Tiger Lake-H core is vastly more efficient at executing instructions per clock than the older Skylake-W core. For database queries, spreadsheet calculations, or any workload with a serial bottleneck, this difference is decisive.

In Geekbench multi-core, the i7-11850HE extends its winning streak with a score of 8,576 versus 8,481. The 1.1% delta is modest but consistent with the trend. Despite having 25% more cores (10 versus 8) and 25% more threads (20 versus 16), the Xeon cannot overcome the i7-11850HE's superior single-core performance and larger L3 cache. The Xeon's quad-channel memory bandwidth of 85.3 GB/s appears to offer no tangible benefit in this test, as the i7-11850HE's dual-channel 51.2 GB/s configuration still yields a higher score.

The Cinebench tests across R15, R20, and R23 all show a near-identical pattern. In R15 multi-core, the i7-11850HE scores 1,753 versus 1,750 (0.2% delta). In R20 multi-core, it scores 7,308 versus 7,294 (0.2% delta). In R23 multi-core, it scores 17,402 versus 17,368 (0.2% delta). These results indicate that the two CPUs are effectively interchangeable for heavily threaded rendering workloads. The Xeon's extra two cores and four threads are completely neutralized by the i7-11850HE's higher clock speeds (4.70 GHz boost versus 4.50 GHz) and superior per-core throughput.

The single-core Cinebench results follow the same narrow pattern. The i7-11850HE wins R15 single-core with 247 versus 246 (0.4% delta), R20 single-core with 1,031 versus 1,029 (0.2% delta), and R23 single-core with 2,456 versus 2,452 (0.2% delta). These margins are within measurement noise. The only conclusion to draw is that in pure Cinebench single-threaded workloads, neither CPU offers a meaningful advantage over the other. The real separation is reserved for Geekbench, where the i7-11850HE demonstrates a profound lead.

Architecture Differences

The architectural divide between these two CPUs is substantial. The Intel Core i7-11850HE is built on a 10 nm process node using the Tiger Lake-H architecture, with a die size of 190 mm². It features 8 cores and 16 threads, with a base clock of 2.10 GHz and a boost clock of 4.70 GHz. Its cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a 24 MB shared L3. The memory controller supports dual-channel DDR4 with a bandwidth of 51.2 GB/s. It uses the Intel BGA 1787 socket, is classified as a mobile part, and remains in active production. The i7-11850HE also includes integrated UHD Graphics (Xe-LP) and supports PCIe Gen 4 with 20 CPU lanes.

The Intel Xeon W-2150B is a fundamentally older design. It uses a 14 nm process node with the Skylake-W architecture and a substantially larger die size of 484 mm². It offers 10 cores and 20 threads, with a base clock of 3.00 GHz and a boost clock of 4.50 GHz. Its cache is smaller: 64 KB of L1 per core, 1 MB of L2 per core, and only 13.75 MB of shared L3. It supports quad-channel DDR4 memory, giving it a higher theoretical bandwidth of 85.3 GB/s, and it includes ECC memory support. The Xeon uses the Intel Socket 2066, targets the server/workstation segment, and is marked as end-of-life. It has no integrated graphics and provides PCIe Gen 3 with 48 CPU lanes.

The most impactful differences are the process node (10 nm versus 14 nm) and the L3 cache size (24 MB versus 13.75 MB). The newer 10 nm Tiger Lake design enables higher IPC and lower power consumption (35 W TDP versus 120 W TDP). The larger L3 cache on the i7-11850HE likely explains its dramatic 51% Geekbench single-core advantage, as more data can be held on-die. The Xeon's advantages are limited to ECC support, quad-channel memory, and a higher base clock, none of which translate into benchmark victories. The production status also matters: the i7-11850HE is active, while the Xeon W-2150B is end-of-life, indicating which platform will receive longer-term support.
