AMD Ryzen 9 3950X vs Intel Xeon W-1290E Comparison

Head-to-Head Benchmarks

The two processors share identical overall percentile rankings, both sitting at the 59th percentile among all CPUs tracked in the database. Their average benchmark scores are also remarkably close, with the AMD Ryzen 9 3950X averaging 4807 and the Intel Xeon W-1290E averaging 4775 — a difference of just 0.7 percent. Yet the head-to-head results show a dramatic split depending on workload type.

In Cinebench R15 multicore, the AMD Ryzen 9 3950X delivers a score of 4002, while the Intel Xeon W-1290E manages only 1664. That represents a 140.5 percent advantage for the AMD part — more than double the Intel processor's output. This is the single largest gap between the two chips in any shared benchmark. The 16-core, 32-thread Ryzen 9 simply overwhelms the 10-core, 20-thread Xeon in heavily threaded rendering workloads.

The situation reverses entirely in Cinebench R15 single-core. Here, the Intel Xeon W-1290E scores 234 versus the Ryzen 9's 209, giving Intel a 10.7 percent lead. The Xeon's 4.80 GHz boost clock, compared to the Ryzen 9's 4.70 GHz, helps explain this edge in lightly threaded tasks. Intel's Comet Lake architecture also benefits from higher per-core frequency headroom, even if it cannot match AMD's core count.

It is notably the two chips have different benchmark suites recorded in the database. The Ryzen 9 3950X has results for 3DMark tests across various thread counts (726 single-thread, 1436 two-thread, 2795 four-thread, 5299 eight-thread, 9338 sixteen-thread, and 10719 max-thread), along with Geekbench scores of 1454 single-core and 12088 multi-core. The Xeon W-1290E instead has Cinebench R20 and R23 results, scoring 978 and 2330 in single-core, and 6934 and 16510 in multi-core respectively. These additional data points cannot be directly compared, but they provide context for each chip's performance envelope.

Architecture Differences

The AMD Ryzen 9 3950X uses TSMC's 7 nm process node, while the Intel Xeon W-1290E relies on Intel's 14 nm node. This process gap explains significant differences in transistor density and power efficiency. The Ryzen 9 integrates 7,600 million transistors across a dual-chiplet design with a die size of 2x 74 mm². The Xeon, by contrast, uses a monolithic 206 mm² die with no transistor count listed in the data.

Both processors support DDR4 memory in a dual-channel configuration. However, the Ryzen 9 offers 51.2 GB/s of memory bandwidth versus the Xeon's 46.9 GB/s — a 9 percent advantage for AMD. The Ryzen 9 also supports PCIe Gen 4 with 24 CPU lanes, whereas the Xeon is limited to PCIe Gen 3 with 16 lanes.

Cache hierarchies differ substantially. Both share 64 KB of L1 cache per core. The Ryzen 9 has 512 KB of L2 per core and 64 MB of L3 cache, while the Xeon has 256 KB of L2 per core and 20 MB of shared L3. AMD's larger L3 pool benefits multi-threaded workloads that share data across cores.

The Xeon W-1290E includes integrated Intel UHD Graphics P630, while the Ryzen 9 has no integrated graphics listed. The Xeon also supports ECC memory, which the Ryzen 9 does not. AMD's chip has an unlocked multiplier, enabling overclocking, while Intel's is locked. The Ryzen 9 targets the desktop market segment, while the Xeon is positioned for server and workstation use.

The Verdict

The data presents a clear split: the AMD Ryzen 9 3950X is the superior choice for multi-threaded, core-heavy workloads, while the Intel Xeon W-1290E wins in single-threaded tasks and offers features relevant to server environments.

In the only direct head-to-head comparison available, the Ryzen 9's 140.5 percent multicore advantage is overwhelming. With 16 cores against the Xeon's 10, 32 threads against 20, and 64 MB of L3 against 20 MB, the AMD part is engineered for parallel throughput. Its 51.2 GB/s memory bandwidth also exceeds the Xeon's 46.9 GB/s, supporting data-intensive operations.

However, the Xeon W-1290E counters with a 10.7 percent single-core win in Cinebench R15. Its higher boost clock of 4.80 GHz versus 4.70 GHz gives it an edge in lightly threaded applications. The Xeon also provides ECC memory support, integrated graphics, and a lower TDP of 95 W versus 105 W — features that matter in workstation reliability contexts.

The Ryzen 9's unlocked multiplier and PCIe Gen 4 support make it more flexible for desktop enthusiasts. The Xeon's locked multiplier and PCIe Gen 3 reflect its server-oriented design philosophy.

Average benchmark scores place the two chips nearly identically, with the Ryzen 9 at 4807 and the Xeon at 4775. Both occupy the 59th percentile of all CPUs. The choice between them depends entirely on workload character, not overall capability.

Where Each One Wins

AMD Ryzen 9 3950X wins in:

• Multi-threaded rendering and compute workloads, as demonstrated by its 4002 Cinebench R15 multicore score versus the Xeon's 1664
• Memory bandwidth, offering 51.2 GB/s versus 46.9 GB/s
• Cache capacity, with 64 MB L3 versus 20 MB
• PCIe connectivity, providing Gen 4 with 24 lanes versus Gen 3 with 16 lanes
• Overclocking flexibility, courtesy of its unlocked multiplier
• Overall thread throughput, with 32 threads versus 20

Intel Xeon W-1290E wins in:

• Single-threaded performance, scoring 234 versus 209 in Cinebench R15 single-core
• Maximum frequency, boosting to 4.80 GHz versus 4.70 GHz
• Power efficiency at the package level, with 95 W TDP versus 105 W
• ECC memory support, critical for error-tolerant computing
• Integrated graphics, providing Intel UHD Graphics P630 where the Ryzen 9 has none
• Server/workstation market fit, with platform features aligned to that segment

The 3DMark results for the Ryzen 9 tell a story of scalability: scores climb from 726 single-thread to 10719 max-thread, showing strong multi-core scaling. The Xeon's Cinebench R23 results (2330 single-core, 16510 multi-core) reveal a similar pattern but with less headroom given its lower core count. Users who prioritize rendering, simulation, or compilation should choose AMD. Users who need ECC memory, integrated graphics, or maximum single-thread responsiveness should choose Intel.
