The Verdict

The data paints a clear picture for different user profiles. The AMD Ryzen Threadripper PRO 5975WX is the default choice for workloads that are heavily parallel and integer-focused. Its 33.9% lead in PassMark Integer Math and 33.3% lead in PassMark Data Encryption show that it is a computing powerhouse for tasks that can utilize all 32 cores. It also wins the majority of the Cinebench multi-core tests, making it the stronger candidate for 3D rendering and video encoding where every bit of multi-threaded throughput counts.

The Intel Xeon 6527P, despite having fewer cores, is the better option for specific, latency-sensitive tasks. Its dominant 45.8% win in PassMark Physics indicates superior single-thread and lightly-threaded performance. Furthermore, its support for DDR5 memory and double the bandwidth (409.6 GB/s vs 204.8 GB/s) makes it the more logical choice for memory-bandwidth-intensive applications like in-memory databases or large-scale data analytics. If your primary software relies on high-speed memory access or benefits from the higher 4.20 GHz boost clock, the Intel part is the better fit.

The overall verdict is that the AMD part wins on sheer compute volume, while the Intel part wins on architectural efficiency in specific areas. The 12-to-5 win count in the head-to-head benchmarks heavily favors the AMD Ryzen Threadripper PRO 5975WX, but the specific nature of the Intel wins should not be ignored for specialized workloads.

Head-to-Head Benchmarks

The most significant victories for the AMD Ryzen Threadripper PRO 5975WX are in integer-heavy and encryption tasks. The data shows a 33.9% lead in PassMark Integer Math (360156 vs 268985) and a 33.3% lead in PassMark Data Encryption (80453 vs 60333), highlighting a massive computational advantage in these areas. The AMD part also achieves a 25.5% lead in PassMark Data Compression (1293784 vs 1030818), making it the clear winner for file archiving and compression workloads. In the Cinebench suite, the AMD processor consistently holds a slight but uniform edge, winning all six tests by 1.2% or less, including a 1.2% lead in both R23 multi-core (64021 vs 63278) and R23 single-core (9038 vs 8933).

The Intel Xeon 6527P’s wins are fewer but extremely pronounced. Its most impressive result is in PassMark Physics, where it scores 8037 against the AMD’s 4360, a staggering 45.8% advantage that suggests a fundamentally different performance profile for physics simulations. It also wins in PassMark Single Thread (3539 vs 3323, a 6.1% lead) and PassMark Random String Sorting (131597 vs 123527, a 6.1% lead). The Intel part also takes PassMark Find Prime Numbers (508 vs 438, a 13.8% lead). These wins are in tasks that often rely on lower latency and higher clock speeds, which the Intel part’s 4.20 GHz boost clock supports. Despite these strong showings, the overall average benchmark score still favors the AMD part, as the Intel’s wins, while large in percentage, are in fewer tests.

Specification Differences

The two processors differ significantly in their core and memory configurations. The AMD Ryzen Threadripper PRO 5975WX features 32 cores and 64 threads, while the Intel Xeon 6527P has 24 cores and 48 threads. The base clock of the AMD part is 3.60 GHz, which is higher than the Intel’s 3.00 GHz, and its boost clock is 4.50 GHz compared to the Intel’s 4.20 GHz. The thermal design power (TDP) also differs, with the AMD part rated at 280W and the Intel part at 255W.

Memory support is a major differentiator. The AMD Ryzen Threadripper PRO 5975WX supports DDR4 memory with a bandwidth of 204.8 GB/s, while the Intel Xeon 6527P supports the newer DDR5 standard with a much higher bandwidth of 409.6 GB/s. Both use an eight-channel memory bus and support ECC memory. PCIe capabilities also differ: the AMD part offers Gen 4 with 128 lanes (CPU only), whereas the Intel part offers Gen 5 with 88 lanes (CPU only). The processors also use different sockets, with the AMD part on AMD Socket WRX8 and the Intel part on Intel Socket 4710.

Architecture Differences

The architectural divide is stark, representing two distinct generations and design goals. The AMD Ryzen Threadripper PRO 5975WX is built on the Zen 3 architecture (codename Chagall PRO) using a 7 nm process from TSMC. It is a chiplet design with a die size of 4x 81 mm² and contains 16,600 million transistors. Its cache hierarchy includes 64 KB of L1 and 512 KB of L2 per core, with a large 128 MB of L3 cache.

In contrast, the Intel Xeon 6527P is based on the Granite Rapids architecture (Granite Rapids-SP) and is built on Intel’s 5 nm process. It uses a monolithic die that is significantly larger at 598 mm². The cache configuration is different: each core has 112 KB of L1 and 2 MB of L2, and the L3 cache is 144 MB shared across all cores. The Intel part also features integrated graphics as "N/A", while the AMD part has no integrated graphics listed. These differences in process node, cache layout, and die design contribute to the distinct performance characteristics seen in the benchmarks, with the AMD part favoring multi-core throughput and the Intel part showing strengths in memory bandwidth and specific single-thread tasks.
