AMD Ryzen 5 PRO 1600 vs Intel Xeon E5-1650 v4 Comparison

The Intel Xeon E5-1650 v4 and the AMD Ryzen 5 PRO 1600 are both 6-core, 12-thread desktop processors, but they represent divergent design philosophies from different eras. The Xeon is a high-TDP, quad-channel memory workstation part built on Intel's Broadwell-EP architecture, while the Ryzen is a power-efficient, dual-channel mainstream chip based on AMD's original Zen microarchitecture. Benchmark data shows a clear sweep for the AMD processor across every tested workload, though the Intel part retains specific platform advantages that matter for certain professional use cases.

Where Each One Wins

The data is unambiguous: the AMD Ryzen 5 PRO 1600 wins every single benchmark in the head-to-head comparison. Across all six tests—three Cinebench versions, each with single-core and multi-core variants—the Ryzen takes the top spot. This includes both the multi-threaded rendering workloads where more efficient core utilization matters, and the single-threaded tests where clock speed and IPC typically dominate. The Ryzen's advantage is remarkably consistent, ranging from 4.2% to 4.6% across the board.

The Intel Xeon E5-1650 v4, by contrast, does not win a single benchmark in this pairing. Its wins are not in raw compute performance but in platform-level capabilities. With a 140W TDP compared to the Ryzen's 65W, the Xeon is clearly designed for sustained, high-throughput workloads that stress memory bandwidth. It supports quad-channel DDR4 memory with a peak bandwidth of 76.8 GB/s, while the Ryzen is limited to dual-channel with no listed bandwidth figure. The Xeon also provides 40 PCIe Gen 3 lanes from the CPU, whereas the Ryzen's PCIe configuration is not specified in the data. For users building systems around large datasets, multiple GPUs, or high-speed storage arrays, the Xeon's I/O and memory subsystem is the deciding factor.

The Ryzen's wins are in raw compute, power efficiency, and platform longevity. It is still marked as "Active" in production status, while the Xeon is "End-of-life." The Ryzen also has an unlocked multiplier, allowing for overclocking, whereas the Xeon is locked. In terms of benchmark percentiles, the Ryzen sits at the 51st percentile of all CPUs, while the Xeon is at the 52nd, indicating they are statistically peers in overall performance despite the Ryzen's consistent lead in direct comparisons.

Architecture Differences

The two processors are built on the same 14 nm process node but by different foundries. Intel manufactures the Xeon E5-1650 v4 in-house, using 3,400 million transistors on a 246 mm² die. AMD uses GlobalFoundries for the Ryzen 5 PRO 1600, packing 4,800 million transistors into a smaller 192 mm² die. This transistor density difference is notable: the Ryzen crams 40% more transistors into roughly 22% less silicon area, reflecting the different design priorities of the two architectures.

The Xeon uses Intel's Broadwell-EP architecture, a refinement of the Haswell design, while the Ryzen is based on AMD's first-generation Zen architecture, codenamed Summit Ridge. Cache hierarchies differ substantially. The Xeon allocates 64 KB of L1 and 256 KB of L2 cache per core, with a shared 15 MB L3 cache. The Ryzen gives each core 96 KB of L1 and 512 KB of L2, with a larger 16 MB shared L3. This means the Ryzen has more cache at every level, which helps explain its consistent performance advantage in latency-sensitive and cache-dependent workloads.

Memory support is a major differentiator. The Xeon supports quad-channel DDR4 with a rated bandwidth of 76.8 GB/s, while the Ryzen is limited to dual-channel with no official bandwidth figure provided. ECC memory is supported on the Xeon but not on the Ryzen, a critical feature for error-sensitive workstation and server environments. The Xeon also offers 40 PCIe Gen 3 lanes directly from the CPU, while the Ryzen's PCIe configuration is not listed. Clock speeds favor the Intel chip: the Xeon runs at 3.60 GHz base and 4.00 GHz boost, versus the Ryzen's 3.20 GHz base and 3.60 GHz boost. Despite the 400 MHz clock disadvantage, the Ryzen still wins in every benchmark, pointing to superior instructions-per-clock (IPC) in the Zen architecture.

Head-to-Head Benchmarks

The Cinebench R15 multi-core test shows the Ryzen scoring 1013 against the Xeon's 966, a 4.6% difference. This is the largest margin in the entire comparison. The single-core R15 test is closer: 142 for the Ryzen versus 136 for the Xeon, a 4.2% gap. This pattern repeats across every generation of the Cinebench suite, suggesting a consistent architectural advantage rather than a workload-specific quirk.

Cinebench R20 multi-core results show the Ryzen at 4224 and the Xeon at 4028, again a 4.6% margin. The single-core R20 test gives the Ryzen 595 points to the Xeon's 568, a 4.5% difference. These scores scale proportionally from R15, indicating that the performance ratio is stable as the rendering workload becomes more demanding.

The most recent Cinebench R23 tests confirm the trend. Multi-core scores are 10058 for the Ryzen and 9592 for the Xeon, maintaining the exact 4.6% gap seen in R15 and R20. Single-core R23 results are 1419 versus 1354, a 4.6% difference. This consistency across three major benchmark versions is remarkable—the AMD chip is uniformly 4-5% faster in every scenario, whether the workload is heavily threaded or entirely single-threaded. The data suggests this is not a case of one processor being better at specific tasks, but rather the Ryzen being fundamentally more efficient at executing the same instructions.

The Geekbench results are only available for the Xeon, which scores 6060 multi-core and 1122 single-core. No direct comparison is possible for this test, but the Xeon's average benchmark score of 2978 across all tests places it slightly above the Ryzen's 2909 average. This apparent contradiction—the Xeon having a higher average score but losing every head-to-head test—is explained by the fact that the Geekbench tests are included in the Xeon's average but not in the Ryzen's benchmark suite, and the averages draw from different test sets.

The Verdict

The benchmark data is decisive: the AMD Ryzen 5 PRO 1600 is the faster processor in every measured workload. It wins all six head-to-head comparisons by margins of 4.2% to 4.6%, covering both single-core and multi-core performance across three generations of Cinebench. The Ryzen achieves this despite running at lower clock speeds (3.60 GHz boost versus 4.00 GHz boost) and consuming less than half the power (65W versus 140W TDP). For users who prioritize raw compute performance, rendering throughput, and power efficiency, the Ryzen is the clear choice.

However, the Intel Xeon E5-1650 v4 is not without purpose. Its quad-channel memory controller with 76.8 GB/s bandwidth and 40 PCIe Gen 3 lanes make it the superior platform for memory-bandwidth-bound applications and multi-GPU configurations. The Xeon also supports ECC memory, which is essential for long-running compute tasks where data integrity is paramount. The Ryzen lacks ECC support entirely. For workstation builders who need maximum memory throughput, PCIe expansion capacity, or error-correcting memory, the Xeon's platform features outweigh its compute deficit.

The production status is also relevant. The Xeon is end-of-life, meaning no new supply is being manufactured, while the Ryzen remains active in production. The Ryzen also has an unlocked multiplier, enabling overclocking to potentially close or extend the performance gap further. The Xeon's launch MSRP was $621, though no pricing data is available for the Ryzen. Users building new systems today would likely favor the active, more efficient, and consistently faster Ryzen, while those maintaining existing Xeon-based workstations with specific I/O or memory requirements may find the Intel part still meets their needs.
