AMD Ryzen Threadripper PRO 5965WX vs Intel Xeon w7-2575X Comparison

Head-to-Head Benchmarks

The benchmark data presents a largely one-sided contest. The AMD Ryzen Threadripper PRO 5965WX wins 16 of the 17 recorded head-to-head tests, while the Intel Xeon w7-2575X manages a single victory. The margin of that Intel win is notable, but it is the exception in an otherwise dominant AMD performance profile.

In Cinebench testing, the AMD part is consistently ahead by a wide margin. Across Cinebench R15, R20, and R23, the multi-core deltas are remarkably uniform: the Threadripper PRO 5965WX leads by 27.4% in every multi-core test. The single-core results tell the same story, with a 27.3% advantage in R15 and a 27.4% lead in both R20 and R23. The raw scores illustrate the gap: in Cinebench R23 multi-core, AMD scores 56400 against Intel's 44277, and in single-core the AMD chip posts 7962 versus 6250.

PassMark testing reveals where each processor excels. The AMD chip's largest win comes in PassMark find prime numbers, where it scores 523 against Intel's 218, a staggering 139.9% delta. PassMark physics is another dominant result for AMD: 4251 versus 2222, a 91.3% advantage. The data encryption test shows a 60.6% lead for AMD, with scores of 63113 and 39295 respectively. These are not marginal differences; they represent substantial performance gaps in compute-heavy workloads.

The Intel Xeon w7-2575X's sole head-to-head victory comes in PassMark floating point math. It scores 171427 against AMD's 157708, an 8% advantage. This is a meaningful result for workloads that rely heavily on floating-point throughput, but it stands alone in the dataset.

Elsewhere, the AMD processor holds a 27.9% lead in both PassMark data compression and integer math, and a 27.3% edge in random string sorting. The multi-thread PassMark score favors AMD by 27.4%, at 66353 versus 52091. Extended instructions show a closer contest, with AMD ahead by just 7.7%, scoring 67300 against 62498. Single-thread PassMark results are nearly identical: AMD posts 3337, Intel posts 3300, a difference of only 1.1%. That narrow margin suggests that in lightly threaded, single-core scenarios, the two processors are effectively comparable, despite their architectural differences.

The average benchmark scores in the database place the AMD part at 98504, while the Intel processor sits at 88172. The AMD chip also holds a higher percentile ranking among all CPUs at 97, versus 96 for Intel. These aggregate figures reinforce the head-to-head results: the Threadripper PRO 5965WX is the stronger overall performer in this comparison.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Threadripper PRO 5965WX is built on TSMC's 7 nm process node, while the Intel Xeon w7-2575X uses Intel's 10 nm node. The AMD chip is based on the Zen 3 architecture, codenamed Chagall PRO, and belongs to the Ryzen Threadripper generation. Intel's part uses the Sapphire Rapids codename and belongs to the Xeon W generation.

Core and thread counts differ, with AMD offering 24 cores and 48 threads, while Intel provides 22 cores and 44 threads. The AMD processor has a base clock of 3.80 GHz and a boost clock of 4.50 GHz. Intel's base clock is lower at 3.00 GHz, but its boost clock is higher at 4.80 GHz. This explains why single-thread PassMark scores are so close: Intel's higher boost clock offsets some of AMD's architectural advantages in lightly threaded work.

Cache hierarchies are structured differently. The AMD chip features 64 KB of L1 cache per core, 512 KB of L2 cache per core, and a substantial 128 MB of L3 cache. Intel's design uses 80 KB of L1 per core, a much larger 2 MB of L2 per core, but only 45 MB of L3. The AMD part's large L3 cache is a significant advantage for workloads that benefit from large shared pools of fast memory.

Memory support diverges sharply. AMD uses DDR4 memory across an eight-channel bus, delivering a memory bandwidth of 204.8 GB/s. Intel uses DDR5 memory on a quad-channel bus, with a lower peak bandwidth of 153.6 GB/s. Although DDR5 is a newer standard, the AMD part's extra memory channels give it a bandwidth advantage in the recorded specifications.

PCIe capabilities also differ. The AMD processor provides Gen 4 connectivity with 128 lanes from the CPU, while Intel offers Gen 5 with 64 lanes. The newer PCIe standard on Intel's side may appeal to users with Gen 5 peripherals, but AMD's lane count is far higher.

The transistor count for AMD is listed at 16,600 million across a die size of 4x 81 mm². Intel's transistor count and die size are not recorded in the database. The AMD part's multi-die design explains the 16,600 million transistor figure, as well as the four separate die tiles listed.

Power ratings place AMD at 280 W TDP and Intel at 250 W TDP. Both processors support ECC memory, and both target the server and workstation market segment. Intel's part has an unlocked multiplier, while AMD's is locked. The production status for both is listed as active.

Where Each One Wins

The AMD Ryzen Threadripper PRO 5965WX is the clear choice for multi-threaded, compute-intensive workloads. Its 27.4% lead across every Cinebench multi-core test indicates strong scaling across its 24 cores and 48 threads. The PassMark physics result, where AMD leads by 91.3%, points to particular strength in simulation and physics-based applications. The 139.9% advantage in find prime numbers suggests exceptional integer throughput in certain algorithmic workloads.

Data encryption is another AMD stronghold, with a 60.6% lead. This matters for security-focused tasks, database encryption, and any workload that relies heavily on cryptographic operations. The 27.9% advantage in data compression and integer math further solidifies the AMD part's position for general productivity and content creation workloads.

The Intel Xeon w7-2575X wins in floating point math, with an 8% advantage. This is relevant for scientific computing, financial modeling, and other workloads where floating-point operations dominate. The higher boost clock of 4.80 GHz also gives Intel an edge in bursty, single-threaded tasks, although the recorded single-thread PassMark scores show only a 1.1% difference, meaning this advantage is marginal in practice.

For users with Gen 5 PCIe devices, Intel's support for Gen 5 with 64 lanes may be preferable despite the lower lane count. The AMD part's 128 lanes of Gen 4 offer more total connectivity, but older generation bandwidth per lane.

Specification Differences

The two processors differ across several key specification fields. The AMD Ryzen Threadripper PRO 5965WX offers 24 cores and 48 threads, while the Intel Xeon w7-2575X provides 22 cores and 44 threads. AMD's base clock is 3.80 GHz compared to Intel's 3.00 GHz, but Intel's boost clock reaches 4.80 GHz versus AMD's 4.50 GHz.

Power consumption differs, with AMD rated at 280 W TDP and Intel at 250 W TDP. The sockets are incompatible: AMD uses Socket WRX8, while Intel uses Socket 4677. The AMD part is built on a 7 nm process from TSMC, while Intel uses a 10 nm process from its own fabs.

Cache configurations vary significantly. AMD provides 64 KB of L1 per core, 512 KB of L2 per core, and 128 MB of L3. Intel offers 80 KB of L1 per core, 2 MB of L2 per core, and 45 MB of L3. Memory support splits along generational lines: AMD uses DDR4 with an eight-channel bus and 204.8 GB/s bandwidth, while Intel uses DDR5 with a quad-channel bus and 153.6 GB/s bandwidth.

PCIe connectivity favors AMD in lane count, with 128 Gen 4 lanes, while Intel provides 64 Gen 5 lanes. The AMD processor has an integrated graphics field listed as null, while Intel lists N/A. The AMD part's multiplier is locked, while Intel's is unlocked. Release dates differ as well: AMD launched on March 7, 2022, while Intel launched on August 23, 2024. The AMD part's launch MSRP is $2399, and Intel's launch MSRP is $1689. Transistor count and die size are recorded for AMD (16,600 million transistors across 4x 81 mm² dies), but not for Intel.
