Intel Xeon 6357P vs Intel Xeon 6507P Comparison

# Intel Xeon 6357P vs Intel Xeon 6507P: Two 8-Core Xeons, Two Different Philosophies

Both processors share the same core count, thread count, and 87th percentile ranking among all CPUs, yet their benchmark profiles could hardly be more different. The Intel Xeon 6357P leverages a high 5.40 GHz boost clock to dominate single-threaded workloads, while the Intel Xeon 6507P counters with a more balanced architecture that wins 12 of 17 head-to-head tests. The 6357P takes five wins, including a commanding 16.2% lead in single-thread performance, but the 6507P prevails in nearly every multi-threaded and memory-sensitive benchmark. These are not interchangeable server parts; they are optimized for distinct deployment scenarios.

Where Each One Wins

The Intel Xeon 6357P is the clear choice for latency-sensitive, lightly threaded workloads. Its PassMark single-thread score of 4233 versus 3643 for the 6507P represents a 16.2% advantage, the largest margin in any benchmark between these two chips. This translates directly to faster response times in database queries, web serving, and any application where a single core dictates performance. The 6357P also wins in integer math (97375 vs 88877, a 9.6% lead) and floating-point math (74460 vs 69604, a 7% lead), indicating superior raw arithmetic throughput per core. Data encryption is another 6357P strength, with a 3.2% edge (18324 vs 17753).

The Intel Xeon 6507P, by contrast, is the multi-threaded workhorse. It wins every Cinebench test, from R15 multicore (2676 vs 2635, 1.5% ahead) through R23 multicore (26548 vs 26145, 1.5% ahead). The spread grows in specialized workloads: physics simulation shows a 21.5% advantage (2935 vs 2305), and prime number finding is 33.5% faster (224 vs 149). Random string sorting (39682 vs 35495) and extended instructions (27385 vs 24490) both show 10.6% leads for the 6507P. Even data compression, a common server task, favors the 6507P by 0.7% (356190 vs 353521). For workloads that scale across all 16 threads, the 6507P is consistently ahead, albeit with margins that vary from marginal to massive.

Architecture Differences

The two CPUs come from entirely different Intel design families. The 6357P is built on Raptor Lake, specifically the Raptor Lake-R refresh, using a 10 nm process node with a 257 mm² die size. It uses the Intel Socket 1700 platform and belongs to the Xeon 6 generation (Raptor Lake Refresh). The 6507P, meanwhile, is a Granite Rapids part, built on a 5 nm process node, and uses the Intel Socket 4710 platform within the Xeon 6 (Granite Rapids-SP) generation.

Cache hierarchies differ significantly. The 6357P provides 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3. The 6507P offers more L1 (112 KB per core) and doubles the shared L3 to 48 MB, while keeping the same 2 MB per-core L2. This larger L3 cache likely contributes to the 6507P's superior performance in cache-sensitive workloads like random string sorting and extended instruction tests.

Memory architecture is another major divergence. The 6357P supports both DDR4 and DDR5 in a dual-channel configuration, while the 6507P supports only DDR5 but across eight channels, yielding a memory bandwidth of 409.6 GB/s. That eight-channel design is a server-grade feature that the dual-channel 6357P simply cannot match, explaining the 6507P's advantage in memory-intensive benchmarks. PCIe lanes also differ dramatically: the 6357P provides 16 Gen 5 lanes, while the 6507P offers 88 Gen 5 lanes, enabling far more expansion and I/O connectivity. Both support ECC memory and lack integrated graphics, targeting the server and workstation segment.

Head-to-Head Benchmarks

The Cinebench suite tells a consistent story. Across all six Cinebench tests (R15, R20, R23, each in single and multi-core variants), the 6507P wins every time with nearly identical 1.3% to 1.5% margins. The R15 multicore score of 2676 vs 2635 and the R23 multicore score of 26548 vs 26145 both show the 6507P's modest but consistent edge. Single-core Cinebench results follow suit: R15 single-core is 377 vs 372, R20 single-core is 1573 vs 1550, and R23 single-core is 3747 vs 3691, each a 1.5% win for the 6507P.

The PassMark suite reveals sharper contrasts. The 6357P's biggest win is PassMark single-thread (4233 vs 3643, 16.2% ahead), a direct result of its 5.40 GHz boost clock versus 4.30 GHz for the 6507P. Integer math favors the 6357P by 9.6% (97375 vs 88877), and floating-point math by 7% (74460 vs 69604). Data encryption is closer, with the 6357P ahead 3.2% (18324 vs 17753).

The 6507P counters with its own decisive victories. PassMark physics shows a 21.5% lead (2935 vs 2305), and find prime numbers is the largest gap at 33.5% (224 vs 149). Extended instructions and random string sorting both show 10.6% advantages (27385 vs 24490 and 39682 vs 35495, respectively). PassMark multithread favors the 6507P by 1.5% (31233 vs 30759), and data compression by 0.7% (356190 vs 353521). Notably, the 6507P wins the multithread test even though the 6357P wins both integer and floating-point math, suggesting the 6507P's advantage lies in memory throughput and cache efficiency rather than raw ALU performance.
