AMD Ryzen 5 PRO 6650H vs Intel Xeon 6333P Comparison

Head-to-Head Benchmarks

The benchmark data reveals a split personality between these two six-core, twelve-thread processors. Intel's Xeon 6333P claims nine benchmark wins against six for AMD's Ryzen 5 PRO 6650H, but the margins tell a more nuanced story than the raw win count.

The single most dramatic gap appears in Cinebench R23 multi-core, where the Xeon 6333P scores 15,617 against the Ryzen's 9,561. That is a 63.3% advantage for Intel — the largest delta in the entire comparison. The same test in single-core shows a 49.8% lead (2,204 vs 1,471), confirming that Intel's advantage is not merely a matter of thread scaling but also of raw per-core throughput.

Cinebench R15 multi-core narrows considerably: Intel leads by only 1.5% (1,574 vs 1,550). This is a striking contrast with the R23 result, suggesting the R15 workload does not stress the same resources that give Intel such a commanding lead in the newer benchmark. In R15 single-core, the tables turn — AMD wins by 5.9% (236 vs 222). This is the only Cinebench single-core test where AMD comes out ahead, and it is a modest margin.

PassMark results further complicate the picture. Intel dominates in floating-point math (43,801 vs 35,743, a 22.5% lead) and in the find-prime-numbers test (83 vs 52, a 59.6% advantage). Intel also wins PassMark physics by 57.5% (1,320 vs 838) and single-thread by 10.9% (3,450 vs 3,110). The multithread PassMark score is close — Intel leads by 2.4% (18,374 vs 17,936) — reinforcing the pattern that Intel's edge grows with workloads that favor its architecture.

AMD's wins are concentrated in memory-sensitive and integer-heavy tasks. The Ryzen 5 PRO 6650H takes data compression by 8.2% (217,700 vs 199,886), data encryption by 18.4% (13,518 vs 11,025), and extended instructions by 13.3% (15,044 vs 13,039). Integer math is nearly a tie, with AMD ahead by just 2.2% (62,838 vs 61,458). Random string sorting goes to AMD by 3.6% (22,823 vs 22,010).

The average benchmark scores place both chips at the 76th percentile among all CPUs. The Xeon's average is 23,823, while the Ryzen's is 24,364 — a 2.3% difference in AMD's favor, driven by its strength in the PassMark suite. However, the head-to-head Cinebench data shows Intel's dominance in rendering workloads, which are often more representative of sustained multithreaded performance.

Architecture Differences

The two processors come from fundamentally different design philosophies. Intel's Xeon 6333P uses Raptor Lake architecture on a 10 nm process, fabricated at Intel's own foundries. The die size is 163 mm². AMD's Ryzen 5 PRO 6650H uses Zen 3+ (Rembrandt) on a 6 nm process from TSMC, with a larger 208 mm² die. The process node advantage in transistor density belongs to AMD, but Intel's smaller die suggests a more compact implementation.

Both have six cores and twelve threads, but cache layouts differ significantly. Intel allocates 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 18 MB of shared L3. AMD provides 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. Intel's larger per-core L2 and L3 capacities likely contribute to its advantage in single-threaded and physics workloads, where cache hits reduce memory latency penalties.

Memory support diverges: the Xeon supports both DDR4 and DDR5 in dual-channel mode, while the Ryzen is DDR5-only with dual-channel support and a rated memory bandwidth of 76.8 GB/s. Intel's flexibility with older DDR4 memory is notable for workstation upgrades, though the data does not include bandwidth figures for Intel to compare directly.

ECC memory is supported on the Xeon but not on the Ryzen — a critical differentiator for server and workstation reliability requirements. PCIe connectivity also differs: Intel provides Gen 5 with 16 lanes (CPU only), while AMD provides Gen 4 with 20 lanes (CPU only). The Xeon's newer PCIe generation offers higher per-lane bandwidth, but AMD's greater lane count may suit configurations needing more devices.

Integrated graphics are absent on the Xeon (marked N/A), while the Ryzen includes a Radeon 660M iGPU. The Xeon targets the Server/Workstation segment, whereas the Ryzen is a Mobile part. Both are active in production, but their release dates differ: the Xeon launched on 2025-02-23, while the Ryzen launched on 2022-04-18. The Xeon carries a launch MSRP of $319; the Ryzen has no listed launch MSRP.

Clock speeds favor Intel in boost: 5.20 GHz versus AMD's 4.50 GHz. However, AMD's base clock is higher at 3.30 GHz versus Intel's 3.10 GHz. The Xeon has a 65 W TDP compared to the Ryzen's 45 W TDP, reflecting the higher power envelope for Intel's burst performance. Intel's socket is Socket 1700; AMD uses Socket FP7.

The Verdict

The data supports a clear split: choose the Intel Xeon 6333P for rendering, floating-point math, and workloads that scale with cache and boost clocks. The 63.3% lead in Cinebench R23 multi-core and 49.8% in R23 single-core are decisive margins that outweigh the narrow losses in other tests. The Xeon also wins PassMark physics by 57.5% and find-prime-numbers by 59.6%, indicating strong integer and scientific compute characteristics.

Choose the AMD Ryzen 5 PRO 6650H for data compression, encryption, and extended instruction workloads, where it leads by 8.2%, 18.4%, and 13.3%, respectively. Its higher average benchmark score (24,364 vs 23,823) and lower TDP (45 W vs 65 W) make it attractive for mobile deployments where power efficiency matters. The integrated Radeon 660M provides graphics capability that the Xeon lacks entirely.

The Ryzen's memory bandwidth advantage (76.8 GB/s rated) likely explains its wins in data-heavy PassMark tests. Yet the Xeon's larger cache pool (18 MB L3 vs 16 MB L3, plus 1.25 MB per-core L2 vs 512 KB) gives it an edge in latency-sensitive workloads. The Xeon's ECC memory support and PCIe Gen 5 connectivity further position it for server duties, while the Ryzen's 20 Gen 4 lanes offer more device connectivity.

If the workload is rendering or single-threaded responsiveness, the Xeon 6333P is the data-backed choice. If the workload is encryption, compression, or sustained integer throughput in a power-constrained mobile chassis, the Ryzen 5 PRO 6650H wins. The 76th percentile ranking for both means either sits comfortably above the median CPU, but the Xeon's Cinebench dominance is the standout feature in this comparison.
