AMD Ryzen 5 PRO 5675U vs Intel Xeon E5-1650 v4 Comparison

# AMD Ryzen 5 PRO 5675U vs Intel Xeon E5-1650 v4

The data presents a clear generational contrast: the AMD Ryzen 5 PRO 5675U wins 4 of 6 head-to-head benchmarks, while the Intel Xeon E5-1650 v4 takes the remaining 2, with the overall average benchmark scores nearly identical (2988 vs 2978, a 0.3% delta). The Ryzen 5 PRO 5675U is a 7nm Zen 3 mobile part with a 15W TDP, while the Xeon E5-1650 v4 is a 14nm Broadwell-EP desktop/server processor rated at 140W. Despite the Xeon's higher power envelope and quad-channel memory support, the two processors land at the same 52nd percentile among all CPUs, making this a battle of efficiency versus raw sustained throughput.

The Verdict

For single-threaded performance and power-sensitive workloads, the AMD Ryzen 5 PRO 5675U is the clear choice. It leads by 58.5% in Cinebench R15 single-core (215.5 vs 136) and by 45.9% in Geekbench single-core (1637 vs 1122). The Ryzen also edges out the Xeon in Cinebench R23 single-core, albeit narrowly at 2.5% (1387.5 vs 1354). For battery-operated or thermally constrained systems, the Ryzen's 15W TDP versus the Xeon's 140W TDP makes it the only sensible option in that context.

The Intel Xeon E5-1650 v4, however, takes the multi-threaded crown in the most demanding workloads. It wins Cinebench R23 multi-core by 18% (9592 vs 7866.5) and Geekbench multi-core by 9.3% (6060 vs 5496). This makes it the pick for sustained all-core rendering or heavily threaded server tasks where power draw is irrelevant. The Xeon also supports ECC memory, a feature absent from the Ryzen, and offers quad-channel memory with 76.8 GB/s bandwidth versus the Ryzen's dual-channel 51.2 GB/s.

The data does not support a universal winner. The Ryzen 5 PRO 5675U suits mobile workstations and ultrabooks where single-core responsiveness and low power matter. The Xeon E5-1650 v4 suits rack-mounted servers or desktops with robust cooling where multi-threaded throughput and memory bandwidth dominate. The Xeon's launch MSRP was $621, but the Ryzen's pricing is not listed in the data.

Where Each One Wins

The AMD Ryzen 5 PRO 5675U wins all three single-core benchmarks in the head-to-head set, plus one multi-core test (Cinebench R15 multi-core, 1326 vs 966, a 37.3% lead). Its single-core dominance is most pronounced in older Cinebench R15, where it scores 58.5% higher than the Xeon. This pattern suggests the Ryzen's higher boost clock of 4.30 GHz (versus 4.00 GHz) and modern Zen 3 architecture deliver superior per-thread performance across all tested generations of Cinebench and Geekbench.

The Intel Xeon E5-1650 v4 wins two multi-core benchmarks: Cinebench R23 multi-core and Geekbench multi-core. Its 18% lead in Cinebench R23 multi-core is substantial, indicating that under sustained all-core loads, the Xeon's higher base clock of 3.60 GHz (versus 2.30 GHz) and 140W power budget allow it to outpace the Ryzen. The Xeon also wins Geekbench multi-core by 9.3%, reinforcing that its advantage grows with workload duration and thread count utilization.

Notably, the Ryzen wins Cinebench R15 multi-core despite the Xeon winning the newer R23 multi-core. This suggests the Ryzen's architecture excels in shorter bursts or less optimized workloads, while the Xeon pulls ahead in the more demanding, longer-running R23 test. The Ryzen's 16 MB shared L3 cache versus the Xeon's 15 MB shared L3 is a minor factor, but the Xeon's larger 246 mm² die (versus 180 mm²) and 3,400 million transistors (versus 10,700 million) reflect different design priorities.

Architecture Differences

The Ryzen 5 PRO 5675U is built on TSMC's 7nm process with 10,700 million transistors packed into an 180 mm² die. It uses Zen 3 architecture with the Cezanne-U codename, featuring 6 cores and 12 threads. The cache layout includes 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. It supports DDR4 memory on a dual-channel bus with 51.2 GB/s bandwidth, but lacks ECC support. The integrated Radeon Vega 7 GPU is present, and the chip connects via PCIe Gen 3 with 8 CPU lanes. It is an active, mobile-market processor on AMD Socket FP6 with a 15W TDP.

The Xeon E5-1650 v4 is built on Intel's 14nm process with 3,400 million transistors on a 246 mm² die. It uses Broadwell architecture with the Broadwell-EP codename, also featuring 6 cores and 12 threads. Its cache hierarchy differs: 64 KB L1 per core, 256 KB L2 per core, and 15 MB shared L3. It supports DDR4 on a quad-channel bus with 76.8 GB/s bandwidth and includes ECC memory support. There is no integrated GPU, and the chip provides PCIe Gen 3 with 40 CPU lanes. It targets the desktop market on Intel Socket 2011-3 with a 140W TDP and is end-of-life.

The transistor count difference is striking: the Ryzen has over 3 times more transistors (10,700 million vs 3,400 million) on a smaller die, reflecting the denser 7nm process. The Xeon's larger 14nm die and lower transistor count indicate an older design, but its quad-channel memory and 40 PCIe lanes offer platform-level advantages for server deployments. The Ryzen's 7nm process and 15W TDP versus the Xeon's 14nm and 140W TDP represent a nine-fold power difference, yet the performance gap in multi-core tests is only 18% in the Xeon's favor.

Head-to-Head Benchmarks

The largest win for the AMD Ryzen 5 PRO 5675U comes in Cinebench R15 single-core, where it scores 215.5 against the Xeon's 136, a 58.5% advantage. This is a massive gap that underscores the architectural leap from Broadwell to Zen 3. The Ryzen also dominates Geekbench single-core with 1637 versus 1122, a 45.9% lead. In Cinebench R15 multi-core, the Ryzen scores 1326 versus 966, a 37.3% win, showing that even in older multi-threaded tests, the Ryzen's efficiency and higher boost clock can overcome the Xeon's higher base clock.

The Intel Xeon E5-1650 v4's biggest win is in Cinebench R23 multi-core, where it scores 9592 against the Ryzen's 7866.5, an 18% lead. This is the most demanding benchmark in the set, and the Xeon's 140W power budget allows it to sustain high clocks across all six cores. The Xeon also wins Geekbench multi-core with 6060 versus 5496, a 9.3% margin. In Cinebench R23 single-core, the Ryzen wins narrowly at 1387.5 versus 1354, a 2.5% edge — the closest contest in the entire comparison.

The pattern across these six tests is consistent: the Ryzen wins every single-core test and the older multi-core test, while the Xeon wins the newer, more demanding multi-core tests. The Ryzen's 4 wins to the Xeon's 2 wins in the head-to-head table reflect this split. The Cinebench R15 multi-core result is particularly interesting because it is the only multi-core test the Ryzen wins, and by a large margin (37.3%). This suggests that the Ryzen's advantage diminishes as workloads become longer and more cache-intensive, where the Xeon's quad-channel memory and 15 MB L3 cache (versus 16 MB on the Ryzen, a negligible difference) come into play.

The average benchmark scores tell a similar story: 2988 for the Ryzen versus 2978 for the Xeon, a 0.3% difference in favor of the Ryzen. Both processors sit at the 52nd percentile, and their nearest rivals include the Intel Xeon E-2334 (identical 2988 average score, 0% delta) and the AMD Ryzen 7 PRO 4750U (2965, 0.8% below the Ryzen). The Xeon's rivals list includes the Intel Xeon E-2278GEL (2956, 0.8% below) and the same Ryzen 7 PRO 4750U. This clustering indicates that both processors occupy a similar performance tier despite their vastly different power and platform characteristics.
