Intel Core i9-7920X vs Intel Xeon W-1290P Comparison

Head-to-Head Benchmarks

The recorded data presents a clear split between these two Intel processors. The Intel Core i9-7920X wins seven of the eight head-to-head benchmark comparisons, while the Intel Xeon W-1290P takes a single, decisive victory. The most striking pattern is the consistency of the Core i9-7920X’s lead across all Cinebench workloads, where it posts a 5.2% advantage in every single test, from the older R15 to the newer R23, in both single-core and multi-core configurations. This uniformity suggests a fundamental architectural edge rather than workload-specific optimization.

In multi-core performance, the Core i9-7920X reaches 2015 points in Cinebench R15 compared to 1915 for the Xeon W-1290P. The gap widens slightly in Cinebench R20, with the i9-7920X scoring 8396 against 7983, and in Cinebench R23, the i9-7920X records 19991 versus 19008. Geekbench’s multi-core test shows a similar outcome: 9297 for the i9-7920X and 8852 for the Xeon, a 5% margin. Across these multi-threaded tests, the i9-7920X’s two additional physical cores and four extra threads translate into a measurable, though modest, performance premium.

The single-core picture is more nuanced. The i9-7920X still edges out the Xeon W-1290P in all three Cinebench iterations: 284 versus 270 in R15, 1185 versus 1126 in R20, and 2822 versus 2683 in R23, each a 5.2% difference. However, the Geekbench single-core test flips the result dramatically. The Xeon W-1290P scores 1703, which is 18.1% higher than the i9-7920X’s 1394. This is the largest delta in the entire dataset and indicates that the Xeon’s higher boost clock, reaching 5.30 GHz, has a substantial impact on certain single-threaded workloads that Geekbench emphasizes.

The average benchmark score in the database places the i9-7920X at 5673, slightly above the Xeon W-1290P’s 5443. The percentile rankings are nearly identical, with the i9-7920X at the 61st percentile and the Xeon at the 60th percentile among all CPUs. The Xeon’s nearest rivals include the Intel Core i9-10900X, which averages 5555 and sits 2% above the Xeon, and the AMD EPYC 7351P, which trails by 0.5%. The i9-7920X’s nearest rival, the AMD Ryzen 7 PRO 3700, averages 5610 and is 1.1% behind, while the AMD Ryzen Threadripper 2920X posts a 5730 average, 1% ahead of the i9-7920X.

Where Each One Wins

The use-case split is defined by the benchmark categories. The i9-7920X is the clear choice for sustained multi-threaded rendering and content creation. Its wins across Cinebench R15, R20, and R23 multi-core tests, all by the same 5.2% margin, show that the 12-core, 24-thread configuration provides a consistent advantage in CPU-bound rendering tasks. The 16.5 MB of shared L3 cache and 1 MB per-core L2 cache support this workload profile well.

For single-threaded performance, the data is contradictory. In Cinebench, the i9-7920X wins all three single-core tests by 5.2%, suggesting that its Skylake-X architecture handles those specific instructions more efficiently. But in Geekbench single-core, the Xeon W-1290P is decisively faster by 18.1%. The Xeon’s 5.30 GHz boost clock and 10 Comet Lake cores with 256 KB per-core L2 cache appear to give it a raw speed advantage that Cinebench does not capture. Users running applications with Geekbench-like single-threaded behavior, such as certain legacy software or lightly threaded productivity tools, would see a substantial benefit from the Xeon.

The Xeon W-1290P also brings features that the i9-7920X lacks, which matter for specific deployment scenarios. It supports ECC memory, making it suitable for error-sensitive computing environments. It includes integrated UHD Graphics P630, allowing a system to operate without a discrete graphics card. The i9-7920X has no integrated graphics at all. The Xeon’s 125 W TDP is lower than the i9-7920X’s 140 W, which can simplify cooling in dense systems.

The i9-7920X counters with a higher memory bandwidth ceiling. Its quad-channel DDR4 support yields 85.3 GB/s, compared to the Xeon’s dual-channel 46.9 GB/s. This nearly doubles the available memory throughput, which is critical for memory-intensive workloads like large dataset manipulation or virtualized environments. The i9-7920X also offers 44 PCIe Gen 3 lanes from the CPU, versus 16 lanes on the Xeon, enabling far more expansion cards and high-speed storage devices.

Architecture Differences

The two processors come from different Intel design eras. The Core i9-7920X is built on the Skylake-X architecture with a 14 nm process node, while the Xeon W-1290P uses the Comet Lake architecture on a 10 nm node. The die size difference is notable: the i9-7920X measures 484 mm², more than double the Xeon’s 206 mm². This larger die accommodates the i9-7920X’s 12 cores and 24 threads, against the Xeon’s 10 cores and 20 threads.

Cache hierarchies diverge significantly. Both have 64 KB of L1 cache per core, but the L2 cache differs: the i9-7920X provides 1 MB per core, while the Xeon provides only 256 KB per core. The L3 cache, however, favors the Xeon, with 20 MB shared versus 16.5 MB shared on the i9-7920X. The Xeon’s smaller per-core L2 but larger shared L3 suggests a design optimized for latency-sensitive single-threaded bursts, while the i9-7920X’s generous per-core L2 supports its multi-threaded throughput.

Memory architecture is another major divergence. The i9-7920X uses a quad-channel memory bus, achieving 85.3 GB/s bandwidth. The Xeon W-1290P uses a dual-channel bus, capping at 46.9 GB/s. This is a fundamental difference in memory subsystem capability. The i9-7920X also has more PCIe lanes: 44 Gen 3 lanes from the CPU, compared to 16 on the Xeon. This positions the i9-7920X for high-end desktop workstations with multiple GPUs or NVMe arrays.

The Xeon W-1290P includes integrated graphics in the form of UHD Graphics P630, which the i9-7920X lacks entirely. The Xeon also supports ECC memory, a feature absent on the i9-7920X. The i9-7920X has an unlocked multiplier for overclocking, while the Xeon’s multiplier is locked. Socket compatibility differs as well: the i9-7920X uses Intel Socket 2066, and the Xeon uses Intel Socket 1200.

The production status also differs. The i9-7920X is end-of-life, having been released in September 2017. The Xeon W-1290P is active, released in May 2020. The i9-7920X carries a launch MSRP of $1199. The Xeon’s launch MSRP is $539.
