AMD Ryzen 7 PRO 4750U vs Intel Xeon E5-1650 v4 Comparison

The Intel Xeon E5-1650 v4 and AMD Ryzen 7 PRO 4750U are closely matched overall, with identical 52nd-percentile standings and near-identical average benchmark scores (2978 vs 2965), but their performance profiles diverge sharply depending on the workload and benchmark generation. The Xeon wins in modern multi-threaded and multi-core tests, while the Ryzen dominates older Cinebench versions and single-core Geekbench, making the choice highly dependent on the software environment.

Head-to-Head Benchmarks

The benchmark results are split exactly evenly, with each processor winning three of the six head-to-head comparisons. The most dramatic victory belongs to the AMD Ryzen 7 PRO 4750U in Cinebench R15 multi-core, where it scores 1410 against the Xeon's 966, a 31.5% advantage. This is the largest single delta in the entire comparison, and it flips the expected narrative since the Ryzen is a 15W mobile part while the Xeon is a 140W desktop processor.

The Ryzen also wins Cinebench R15 single-core by a wide margin, posting 181 versus 136 for the Xeon, a 24.9% lead. In Geekbench single-core, the Ryzen again comes out ahead with 1229 versus 1122, an 8.7% edge. These three wins all favor the Ryzen in older or single-threaded workloads, suggesting its Zen 2 architecture has a significant per-core efficiency advantage that was particularly pronounced in earlier benchmark versions.

The Intel Xeon E5-1650 v4 takes the other three tests, and it does so with substantial margins in the modern Cinebench R23 suite. In Cinebench R23 multi-core, the Xeon scores 9592 versus 8359 for the Ryzen, a 14.8% lead. The single-core R23 result also goes to Intel, with 1354 versus 1215, an 11.4% advantage. Additionally, the Xeon wins Geekbench multi-core with 6060 against 5393, a 12.4% margin.

The pattern is clear: the Ryzen dominates the older R15 tests and Geekbench single-core, while the Xeon wins the newer R23 tests and Geekbench multi-core. Neither processor is uniformly faster. The R15 multi-core delta of 31.5% in favor of AMD is the standout number, but the R23 multi-core delta of 14.8% in favor of Intel shows that the Xeon's 15MB of shared L3 cache and higher sustained clocks matter more in modern rendering workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies and manufacturing generations. The Intel Xeon E5-1650 v4 is built on Intel's 14 nm process with a Broadwell-EP architecture, featuring 6 cores and 12 threads. It integrates 3,400 million transistors on a 246 mm² die. In contrast, the AMD Ryzen 7 PRO 4750U uses TSMC's 7 nm process with a Zen 2 (Renoir) architecture, packing 8 cores and 16 threads with 9,800 million transistors on a smaller 156 mm² die.

The transistor density difference is stark: AMD packs nearly three times the transistors into a die that is 90 mm² smaller. This is reflected in the power envelope, where the Xeon has a 140W TDP while the Ryzen is rated at just 15W. The Ryzen's base clock is listed as 1700.00 MHz (a notably low figure for desktop comparison), while its boost clock reaches 4.10 GHz. The Xeon has a 3.60 GHz base clock and a 4.00 GHz boost clock.

Cache layouts also differ significantly. Both have 64 KB of L1 cache per core, but the L2 cache is 256 KB per core on the Xeon versus 512 KB per core on the Ryzen. The L3 cache heavily favors Intel: 15 MB shared on the Xeon versus 8 MB shared on the Ryzen. This larger L3 cache likely contributes to the Xeon's strong Cinebench R23 multi-core performance, as rendering workloads benefit from larger shared pools.

Memory architecture diverges as well. The Xeon supports quad-channel DDR4 with a memory bandwidth of 76.8 GB/s, while the Ryzen uses dual-channel DDR4 or LPDDR4 with 51.2 GB/s bandwidth. The Xeon also supports ECC memory, which the Ryzen does not. PCIe lanes differ: the Xeon provides 40 Gen 3 lanes (CPU only), while the Ryzen offers just 12 Gen 3 lanes. The Ryzen includes integrated Radeon RX Vega 7 graphics, whereas the Xeon has no integrated graphics.

Where Each One Wins

The AMD Ryzen 7 PRO 4750U wins in scenarios that favor high single-threaded performance in older benchmark suites and in any workload where power efficiency is paramount. Its 15W TDP versus the Xeon's 140W makes it the clear choice for mobile or low-power applications. The R15 multi-core result (1410 versus 966) suggests that in legacy software optimized for older instruction sets or lower core counts, the Ryzen's higher per-core IPC gives it a decisive edge. Similarly, its Geekbench single-core score of 1229 versus 1122 indicates that lightweight, latency-sensitive tasks run faster on the AMD part.

The Intel Xeon E5-1650 v4 wins in modern multi-threaded rendering and in Geekbench multi-core. Its Cinebench R23 multi-core score of 9592 versus 8359 demonstrates that current Cinebench versions scale effectively with the Xeon's larger L3 cache and higher sustained clock speeds. The R23 single-core win (1354 versus 1215) is notable because it contradicts the R15 single-core result, suggesting that Intel's architecture handles the newer instruction set more efficiently. The Geekbench multi-core win (6060 versus 5393) reinforces that the Xeon is better for multi-threaded general-purpose computing.

For users running legacy applications or needing extreme power efficiency, the Ryzen is the winner. For users running current-generation rendering software or needing high multi-threaded throughput in a desktop context, the Xeon is the winner. The 12.4% Geekbench multi-core delta in favor of Intel indicates that the Xeon's quad-channel memory and 40 PCIe lanes also make it more suitable for memory-bandwidth-intensive tasks.

The Verdict

The data presents a split decision with no universal winner. The AMD Ryzen 7 PRO 4750U is the choice for anyone prioritizing power efficiency, as its 15W TDP is drastically lower than the Xeon's 140W. It also wins in legacy Cinebench R15 tests and Geekbench single-core, making it better for older software and latency-sensitive tasks. Its 8-core/16-thread configuration and integrated graphics add versatility for mobile or space-constrained systems.

The Intel Xeon E5-1650 v4 is the choice for modern multi-threaded workloads. Its Cinebench R23 multi-core score of 9592 versus 8359 shows a 14.8% advantage in current rendering benchmarks. The Geekbench multi-core win (6060 versus 5393) and the R23 single-core win (1354 versus 1215) indicate that the Xeon's architecture scales better with modern instruction sets. Its quad-channel memory support (76.8 GB/s bandwidth) and 40 PCIe lanes make it suitable for memory-intensive desktop applications.

The identical 52nd percentile ranking and near-identical average scores (2978 versus 2965) mean that for general mixed workloads, the two are effectively equivalent. The deciding factors are the specific software environment and the physical constraints of the system: choose the Ryzen for mobility and efficiency, choose the Xeon for raw modern multi-threaded performance in a desktop chassis. The Ryzen's 31.5% R15 multi-core win is impressive, but the Xeon's 14.8% R23 multi-core win is more relevant for current software.
