Intel Xeon 654 vs Intel Xeon w5-3535X Comparison

Head-to-Head Benchmarks

The head-to-head results are remarkably one-sided. The Intel Xeon 654 wins all 17 recorded benchmark comparisons against the Intel Xeon w5-3535X, with zero wins for the latter. This is not a marginal advantage; the Xeon 654 leads by double-digit percentages in most tests, and by a wide margin in several.

The most dramatic gap appears in PassMark's physics test. The Xeon 654 scores 5,596 versus the w5-3535X's 3,547, a 57.8% advantage. This is the largest delta in the entire head-to-head set, suggesting a substantial difference in how the two processors handle physics simulation workloads. Similarly, the prime number finding test shows the Xeon 654 at 390 against the w5-3535X's 269, a 45% lead. These two tests share a common thread: they stress integer-heavy, latency-sensitive operations where the Xeon 654's architecture appears particularly strong.

Across the Cinebench suite, the Xeon 654 maintains a consistent edge. In Cinebench R15 multi-core, it scores 5,256 versus 4,634, a 13.4% lead. The single-core version of the same test shows a 13.5% gap (742 vs 654). This pattern repeats exactly in R20 and R23: multi-core deltas are 13.4% (21,903 vs. 19,309 in R20; 52,150 vs. 45,974 in R23), and single-core deltas are 13.5% (3,092 vs. 2,725 in R20). The consistency of these percentages across different Cinebench versions suggests a fundamental per-clock or per-core efficiency advantage, not a workload-specific quirk.

The PassMark suite tells a similar story, though with varying margins. Data compression shows a 12% win (818,902 vs. 731,388), data encryption a 10.6% win (40,675 vs. 36,784), and floating-point math an 11.8% win (163,093 vs. 145,924). Integer math is close behind at 11.6% (207,745 vs. 186,158), while extended instructions yield a narrower 5.6% edge (63,539 vs. 60,183). The random string sorting test has the Xeon 654 at 82,828 versus 73,618, a 12.5% lead.

The smallest margin in the entire set is in single-threaded performance. The Xeon 654 scores 3,778 in the PassMark single-thread test, the w5-3535X scores 3,602, a 4.9% edge. This is still a win, but it is far smaller than the multi-core gaps. The same 4.9% delta appears in the duplicate singlethread test entry, confirming the result.

Overall, the patterns are clear. The Xeon 654 leads by roughly 11 to 13% in most memory-intensive and parallel workloads, but by 45 to 58% in specific compute-heavy integer tasks. The smallest advantage appears in single-threaded work, where the difference is under 5%. The data implies that the Xeon 654's core design is not just faster per clock, but that its uncore and cache hierarchy accelerate certain instruction streams far more than others.

Where Each One Wins

The Intel Xeon 654 wins in every recorded category, so the decision is not about choosing which workloads favor one chip; it is about understanding the magnitude of the advantage. The Xeon 654 is strongest in the following areas:

• Physics simulation: With a 57.8% lead, this is the most decisive victory. Any workload that relies heavily on rigid-body dynamics, collision detection, or similar physics calculations will see the largest relative gain.
• Prime number and integer sequences: The 45% win in prime finding suggests that algorithms with heavy branch predictions and integer modulus operations benefit disproportionately.
• General multi-threaded rendering: Cinebench R15/R20/R23 all show 13.4% leads, which is a solid, consistent advantage for 3D rendering tasks.
• Data compression and encryption: Both show double-digit wins (12% and 10.6%), indicating better performance in archiving, database, and network security workloads.

There is no category where the w5-3535X wins. However, it is notably its single-thread score is within 5% of the Xeon 654, so for applications that are heavily latency-bound and single-threaded, the w5-3535X is not far behind. Its 4.9% deficit in single-thread is the smallest gap in the data, meaning that legacy or poorly parallelized software will see a more modest difference.

Specification Differences

The two processors share several platform-level features but differentiate in core count, process node, and memory bandwidth.

• Cores and threads: The Xeon 654 has 18 cores and 36 threads, while the w5-3535X has 20 cores and 40 threads. The w5-3535X has more parallelism, yet it loses in all multi-threaded benchmarks.
• Base clock: The Xeon 654 runs at 3.10 GHz, the w5-3535X at 2.90 GHz. The Xeon 654 has a 0.2 GHz base clock advantage.
• Boost clock: Both are identical at 4.80 GHz.
• TDP: The Xeon 654 is rated at 200W, the w5-3535X at 300W. The w5-3535X draws more power despite losing across tests.
• Socket: The Xeon 654 uses Intel Socket 4710, the w5-3535X uses Intel Socket 4677.
• Process node: The Xeon 654 is built on a 5 nm process, the w5-3535X on a 10 nm process.
• Die size: The Xeon 654 has a dual-die design at 2x 598 mm², the w5-3535X a quad-die at 4x 477 mm².
• L1 cache: The Xeon 654 has 112 KB per core, the w5-3535X has 80 KB per core.
• L2 cache: Both have 2 MB per core.
• L3 cache: The Xeon 654 has 72 MB shared, the w5-3535X has 52.5 MB (total, not per core).

• Unlocked multiplier: Both are unlocked.
• Release date: The Xeon 654 is from February 2026, the w5-3535X from August 2024.

The Xeon 654 is a smaller die (2 dies vs 4), but with a denser process node, higher base clock, larger caches, and higher memory bandwidth. The w5-3535X has more cores and a higher TDP, but the data shows those extra cores do not translate into better performance.

Architecture Differences

The Xeon 654 is built on the Granite Rapids architecture (codenamed Granite Rapids), part of the Xeon 600 generation, on a 5 nm process at Intel's foundry. It uses dual dies, each 598 mm², with a per-core L1 of 112 KB and an L3 of 72 MB shared. It supports 128 PCIe Gen 5 lanes (CPU only) and an eight-channel DDR5 memory bus with 409.6 GB/s bandwidth.

The Xeon w5-3535X is based on the Sapphire Rapids architecture, part of the Xeon W generation, on a 10 nm process. It uses four dies, each 477 mm², with a per-core L1 of 80 KB and an L3 of 52.5 MB. It provides 112 PCIe Gen 5 lanes (CPU only) and an eight-channel DDR5 bus with 307.2 GB/s bandwidth.

The most significant architectural difference is the process node (5 nm vs 10 nm), which explains the Xeon 654's better power efficiency and higher base clock. The die layout also differs: a dual-die design versus a quad-die, which affects inter-die communication latency. The Xeon 654's larger L1 per core (112 KB vs 80 KB) and larger shared L3 (72 MB vs 52.5 MB) provide more on-chip data storage, while its memory bandwidth (409.6 GB/s vs 307.2 GB/s) is 33% higher. Both support ECC memory, have no integrated graphics, and have unlockable multipliers.

The data suggests that the Granite Rapids design, despite fewer cores, has a more efficient core microarchitecture and a better memory subsystem, which yields higher performance in all measured tasks.

The Verdict

The Intel Xeon 654 is the clear choice for any workload that values raw throughput, physics simulation, integer math, or memory-intensive operations. It wins every head-to-head benchmark with margins from 4.9% to 57.8%. For one who runs Cinebench, PassMark, or similar multi-threaded renderers, the Xeon 654’s 13.4% lead in R23 multi-core (52,150 vs 45,974) is a decisive advantage. Its 20-core rival, the w5-3535X, cannot compensate with more cores because the Xeon 654’s higher base clock, larger caches, and faster memory bus produce better results.

The only scenario where the w5-3535X is not a poor choice is if a user specifically needs the 20-core/40-thread count for a software license that charges per core, or if the system requires the Intel Socket 4677 platform. But in pure performance terms, the recorded data shows no reason to prefer the w5-3535X. The Xeon 654 also has a lower TDP at 200 W versus 300 W, which means it delivers more performance with lower power draw. For new system builders, the Xeon 654 is superior in every measured category. The w5-3535X is a slower processor by any metric in the database.
