AMD Ryzen 5 PRO 5675U vs Intel Xeon W-2133 Comparison

Where Each One Wins

The recorded benchmark data splits this comparison cleanly by workload type and by Cinebench version. The AMD Ryzen 5 PRO 5675U takes the older Cinebench R15 tests decisively: it leads by 18.9% in multi-core (1326 vs 1075) and by 29.9% in single-core (215.5 vs 151). Those are large margins, and they indicate that for legacy applications built around shorter, lower-complexity rendering tasks, the Ryzen part is clearly the stronger choice. Its advantage in single-core R15 is especially pronounced, nearly a third faster than the Xeon, which matters for older software that relies heavily on one thread.

The Intel Xeon W-2133 flips the script in the newer Cinebench R23 tests. It wins multi-core by 35.7% (10676 vs 7866.5) and single-core by 8.6% (1507 vs 1387.5). The R23 multi-core result is the single biggest performance gap in this entire comparison, and it shows that under a modern, heavily threaded rendering workload, the Xeon's higher sustained power envelope and older but larger cache configuration translate into a substantial throughput advantage. The single-core R23 win is smaller but still consistent: Intel leads by 8.6%, which is a meaningful edge in modern single-threaded tasks.

So the use-case split is straightforward. If your daily driver involves older Cinebench R15-style workloads, or if you need maximum single-core responsiveness in legacy applications, the AMD Ryzen 5 PRO 5675U wins clearly. If your work is modern multi-threaded rendering, or any task that scales well across cores under sustained load, the Intel Xeon W-2133 is the stronger performer, with a 35.7% lead in R23 multi-core that is hard to ignore. The wins are balanced at 2-2 in the head-to-head tests, but the magnitude of those wins is not balanced: AMD's R15 wins are smaller (18.9% and 29.9%) than Intel's R23 multi-core win (35.7%), though AMD's single-core R15 lead is larger than Intel's single-core R23 lead.

Architecture Differences

The two processors come from opposite ends of the hardware spectrum. The Intel Xeon W-2133 is built on a 14 nm process from Intel, with a 484 mm² die size, and uses the Skylake-W architecture on the Intel Socket 2066 platform. It is a server/workstation part, released in August 2017, and is now end-of-life. The AMD Ryzen 5 PRO 5675U is a mobile processor on the Zen 3 (Cezanne-U) architecture, built on a 7 nm process from TSMC, with a 180 mm² die and 10,700 million transistors. It uses the AMD Socket FP6, was released in April 2022, and remains active in production.

Cache configurations differ significantly. Both have 64 KB of L1 per core, but the Xeon has 1 MB of L2 per core versus the Ryzen's 512 KB per core. The L3 cache is the bigger difference: the Xeon has 8.25 MB shared, while the Ryzen has 16 MB shared. That is nearly double the L3 capacity, which helps the Ryzen in workloads that benefit from larger shared pools of cache. The Xeon's larger L2 per core, however, gives it an edge in latency-sensitive single-threaded access patterns.

Memory architecture also diverges. The Xeon supports quad-channel DDR4 with a memory bandwidth of 85.3 GB/s and ECC memory. The Ryzen supports dual-channel DDR4 with 51.2 GB/s and no ECC. The Xeon's memory bandwidth is 67% higher, which is a major factor in multi-threaded rendering and other bandwidth-hungry tasks. The Ryzen's integrated Radeon Vega 7 graphics is a notable feature, while the Xeon has no integrated graphics at all, requiring a discrete GPU for any display output.

PCIe lanes are another stark contrast: the Xeon provides 48 CPU-only lanes of Gen 3 PCIe, while the Ryzen provides only 8 lanes. For a workstation with multiple GPUs, NVMe drives, or expansion cards, the Xeon's lane count is far more accommodating. The Ryzen's TDP of 15 W is dramatically lower than the Xeon's 140 W, reflecting its mobile design, while the Xeon's higher power budget enables sustained multi-core performance.

Head-to-Head Benchmarks

The head-to-head results in the database show two very different performance profiles. In Cinebench R15 multi-core, the AMD Ryzen 5 PRO 5675U scores 1326 against the Intel Xeon W-2133's 1075, a 18.9% lead for AMD. This is a solid win for the Ryzen, but it is not the largest gap in the comparison. In Cinebench R15 single-core, the Ryzen scores 215.5 against the Xeon's 151, a 29.9% lead. That is the biggest single-core margin in the data, and it demonstrates a significant architectural advantage for AMD in older single-threaded workloads.

Move to Cinebench R23, and the situation reverses. The Xeon W-2133 scores 10676 in multi-core, against the Ryzen's 7866.5, giving Intel a 35.7% lead. This is the largest performance gap of any test in the comparison, and it is a clear indicator that the Xeon's higher power limit and quad-channel memory bandwidth pay off in modern multi-threaded rendering. In R23 single-core, the Xeon scores 1507 against the Ryzen's 1387.5, an 8.6% lead for Intel. This is a modest but consistent win, showing that the Xeon also holds a slight edge in newer single-threaded tasks.

The data reveals a pattern: the Ryzen wins older tests by larger margins in single-core (29.9%) but smaller margins in multi-core (18.9%), while the Xeon wins newer tests by a massive margin in multi-core (35.7%) and a smaller margin in single-core (8.6%). The overall average benchmark score tells a similar story: the Xeon averages 3087, while the Ryzen averages 2988, a difference of about 3.3% in Intel's favor. The percentile rankings are identical at 52 for both, meaning they sit in the same tier relative to all CPUs in the database.

FAQ

The Verdict

The data points to a clear split based on workload modernity and platform requirements. For modern multi-threaded rendering, the Intel Xeon W-2133 is the pick. Its 35.7% lead in Cinebench R23 multi-core is the single largest advantage in the comparison, and its quad-channel memory bandwidth (85.3 GB/s) and 48 PCIe Gen 3 lanes make it a proper workstation part. If you run R23-style workloads or need ECC memory, multiple expansion cards, or sustained multi-core throughput, the Xeon is the better choice, despite its end-of-life status and higher power draw.

For legacy applications and older single-threaded tasks, the AMD Ryzen 5 PRO 5675U wins decisively. Its 29.9% lead in Cinebench R15 single-core and 18.9% lead in R15 multi-core show that older software runs faster on the Zen 3 architecture. The Ryzen also brings integrated graphics, a 16 MB L3 cache, and a 15 W TDP, making it far more efficient and flexible for mobile or low-power builds. Its active production status and newer release date (April 2022 vs August 2017) are practical advantages for anyone buying today.

The average benchmark scores are close: 3087 for the Xeon, 2988 for the Ryzen, with identical 52nd percentile rankings. But the head-to-head tests show that the choice is not about averages, it is about which workload you actually run. If your software is older, pick AMD. If your software is modern and multi-threaded, pick Intel. The Ryzen's R15 wins are large enough to matter for legacy users, but the Xeon's R23 multi-core win is so dominant that it defines the comparison for current rendering workloads.
