Intel Core i9-9980XE vs Intel Xeon W-2195 Comparison

The Intel Core i9-9980XE and Intel Xeon W-2195 are both 18-core, 36-thread processors built on the same 14 nm Skylake architecture and sharing the same 484 mm² die size. They also share identical cache hierarchies: 64 KB of L1 per core, 1 MB of L2 per core, and 24.75 MB of shared L3. Yet the recorded benchmark data reveals a clear and consistent performance gap, with the i9-9980XE winning every head-to-head Cinebench test by exactly 12.4%. This raises the question: what separates these two near-identical silicon designs, and which one should a buyer choose based purely on the numbers?

The Verdict

The data is unambiguous. In every Cinebench test recorded in the database, the Intel Core i9-9980XE outperforms the Intel Xeon W-2195 by a uniform 12.4% margin. This includes both multi-core and single-core workloads across R15, R20, and R23. The i9-9980XE also posts a higher average benchmark score of 7398 compared to the Xeon's 6892, a difference of roughly 7.3% in the aggregate. For anyone prioritizing raw compute performance, the i9-9980XE is the clear choice.

However, the Xeon W-2195 is not without its own advantages. It supports ECC memory, a feature the i9-9980XE lacks, and it offers more PCIe lanes: 48 versus 44. It also has a lower TDP of 140 watts compared to the i9's 165 watts, which may matter in dense workstation builds. The Xeon is also positioned for the server and workstation market segment, while the i9 is a desktop part. So the verdict depends on whether the user needs error-correcting memory and additional I/O lanes, or whether they want the fastest possible Cinebench scores. The benchmark data strongly favors the i9-9980XE for performance, while the Xeon W-2195 wins on platform features that are not directly measured by these tests.

Architecture Differences

Both processors are built on Intel's Skylake architecture, but they belong to different sub-families. The i9-9980XE uses the Skylake-X codename and is part of the Core i9 Extreme (X-Series 9th Gen) generation. The Xeon W-2195 uses the Skylake-W codename and is part of the Xeon W (Skylake-W) generation. This distinction explains their different market positioning: the i9 is a desktop enthusiast part, while the Xeon is aimed at servers and workstations.

The core and thread counts are identical: 18 cores and 36 threads. The cache layout is also the same, with 64 KB of L1 per core, 1 MB of L2 per core, and 24.75 MB of shared L3. Both use the same 14 nm process node and are fabricated by Intel. The die size is identical at 484 mm². Memory support is also the same: DDR4 with a quad-channel bus and a memory bandwidth of 85.3 GB/s.

The key architectural differences lie in clock speeds, power, and platform features. The i9-9980XE has a base clock of 3.00 GHz and a boost clock of 4.50 GHz, while the Xeon W-2195 runs at 2.30 GHz base and 4.30 GHz boost. The i9 also has a higher TDP of 165 watts versus the Xeon's 140 watts. The i9 has an unlocked multiplier, allowing overclocking, while the Xeon's multiplier is locked. The Xeon supports ECC memory, the i9 does not. The Xeon provides 48 PCIe Gen 3 lanes from the CPU, while the i9 provides 44. These differences explain the performance gap: the i9's higher clocks and unlocked multiplier give it a direct advantage in single-threaded and multi-threaded workloads, while the Xeon's lower TDP and ECC support target reliability and stability in server environments.

Head-to-Head Benchmarks

The database records six head-to-head Cinebench tests, and the i9-9980XE wins all six with a consistent 12.4% delta. This uniformity is striking: it suggests the performance difference is driven by clock speed and possibly the unlocked multiplier, rather than any workload-specific behavior.

In Cinebench R15 multi-core, the i9-9980XE scores 2699 against the Xeon's 2401. The single-core R15 test shows 380 versus 338. Moving to R20, the i9 scores 11247 multi-core and 1587 single-core, while the Xeon scores 10007 and 1412 respectively. In R23, the i9 reaches 26780 multi-core and 3780 single-core, compared to the Xeon's 23828 and 3363. Every delta is exactly 12.4%.

The i9-9980XE also has Geekbench scores recorded: 11270 multi-core and 1437 single-core. The Xeon W-2195 does not have Geekbench results in the database, so no direct comparison is possible there. However, the Cinebench results alone paint a clear picture: the i9-9980XE is consistently faster across all rendering and CPU-bound tests.

The average benchmark score reinforces this. The i9-9980XE averages 7398, while the Xeon W-2195 averages 6892. The i9's nearest rival in the database is the AMD EPYC 7282 with an average score of 7409, a delta of -0.1%, meaning the i9 is essentially tied with that EPYC part. The Xeon's nearest rival is the Intel Core i5-3470 with an average of 6906, a delta of -0.2%. This places the Xeon in a lower performance tier despite having the same core count.

Where Each One Wins

The i9-9980XE wins every benchmark test in the head-to-head comparison. Its higher base and boost clocks, combined with an unlocked multiplier, give it a decisive edge in both single-threaded and multi-threaded workloads. The 12.4% lead in Cinebench R15, R20, and R23 is consistent across all six tests, indicating that the i9 is simply the faster processor for CPU-intensive tasks. It also has a lower launch MSRP of $1979 compared to the Xeon's $2553, though price is not a performance metric.

The Xeon W-2195, however, wins on platform features that are not captured by Cinebench. It supports ECC memory, which is critical for error-sensitive server and workstation workloads. It provides 48 PCIe lanes, four more than the i9, which can be beneficial for systems with many expansion cards or NVMe drives. Its TDP of 140 watts is lower than the i9's 165 watts, potentially making it easier to cool in dense chassis. The Xeon is also positioned for the server and workstation market segment, which may come with different validation and reliability expectations.

In summary, the i9-9980XE is the performance champion in every recorded benchmark, while the Xeon W-2195 offers ECC support, more PCIe lanes, and a lower power envelope. The choice between them depends on whether the user prioritizes raw speed or platform-specific features like error-correcting memory and additional I/O. The data shows that for pure compute, the i9-9980XE is the superior part.
