AMD Ryzen 7 PRO 4750GE vs Intel Xeon W-2145 Comparison

The Intel Xeon W-2145 and AMD Ryzen 7 PRO 4750GE are both 8-core, 16-thread processors, but they occupy different market positions. The Xeon W-2145 is a server/workstation part from 2017, while the Ryzen 7 PRO 4750GE is a desktop APU from 2020. The database records head-to-head results across Cinebench and Geekbench, and the data shows a clear pattern: AMD wins 7 of 8 benchmarks, with Intel taking a single, decisive victory.

Head-to-Head Benchmarks

The AMD Ryzen 7 PRO 4750GE leads in every Cinebench test, though by a narrow margin. In Cinebench R15 multi-core, AMD scores 1582 against Intel's 1542, a 2.5% advantage. The same pattern appears in R20 multi-core: AMD 6593 versus Intel 6425, again a 2.5% lead. In R23 multi-core, AMD posts 15699 against Intel's 15299, a 2.5% difference. Single-core results follow the same trend. In R15 single-core, AMD scores 223 versus Intel's 217, a 2.7% lead. In R20 single-core, AMD 930 versus Intel 906, a 2.6% lead. In R23 single-core, AMD 2216 versus Intel 2159, a 2.6% lead. These are consistent, small advantages across the entire Cinebench suite.

The Geekbench results break the pattern. In Geekbench single-core, AMD wins decisively: 1612 versus Intel's 1345, a 16.6% lead. This is the largest margin in AMD's favor. However, in Geekbench multi-core, Intel takes its only win, and it is substantial: 8712 versus AMD's 6430, a 35.5% lead. That is the biggest delta in either direction across all eight tests.

Interpreting these numbers, AMD is the stronger part in rendering workloads as measured by Cinebench, but only by a small amount. Intel's Geekbench multi-core win is large enough to suggest that certain multi-threaded applications, particularly those that stress memory bandwidth or specific instruction paths, will favor the Xeon. The single-core Geekbench result shows AMD's architectural efficiency advantage, which is also reflected in the Cinebench single-core tests, though to a lesser degree.

Where Each One Wins

Based on the recorded benchmarks, AMD wins all Cinebench tests, both multi-core and single-core, and also wins Geekbench single-core. Intel wins only Geekbench multi-core. This split points to distinct use cases.

For users running Cinebench-style rendering tasks, the Ryzen 7 PRO 4750GE is the better choice, even if the margin is only about 2.5%. For single-threaded applications, such as older games or lightly threaded productivity tools, AMD again leads, with a particularly strong showing in Geekbench single-core. The 16.6% advantage there is meaningful.

Intel's Geekbench multi-core win is the outlier. A 35.5% lead suggests that workloads which scale well with memory bandwidth or that use the Xeon's quad-channel memory subsystem will see a significant benefit. The Xeon also has 48 PCIe Gen 3 lanes versus AMD's 16, so systems requiring many expansion cards or high-bandwidth peripherals would favor Intel. Additionally, the Xeon supports quad-channel DDR4 with 85.3 GB/s bandwidth, while AMD is limited to dual-channel at 51.2 GB/s. For data-heavy multi-threaded tasks, that bandwidth difference could explain the Geekbench multi-core result.

AMD, on the other hand, has a 35W TDP versus Intel's 140W, and it includes Radeon Vega 8 integrated graphics. This makes it suitable for compact or power-constrained systems where a discrete GPU is not an option. The data shows that AMD achieves its benchmark scores at a fraction of the thermal envelope, which is a practical advantage for many desktop deployments.

Architecture Differences

The two processors differ fundamentally in architecture. Intel uses the Skylake-W architecture on a 14 nm process, fabricated by Intel. AMD uses Zen 2 (Renoir) on a 7 nm process from TSMC. The die sizes reflect this: Intel's die is 484 mm², while AMD's is 156 mm². AMD also lists 9,800 million transistors, while Intel's transistor count is not recorded.

Cache layouts differ as well. Both have 64 KB of L1 per core, but Intel has 1 MB of L2 per core, while AMD has 512 KB. Intel's L3 is 11 MB shared, AMD's is 8 MB. The memory interface is a major divergence: Intel uses quad-channel DDR4 with 85.3 GB/s bandwidth, AMD uses dual-channel with 51.2 GB/s. PCIe connectivity also differs: Intel provides 48 Gen 3 lanes (CPU only), AMD provides 16.

AMD includes integrated Radeon Vega 8 graphics; Intel has no integrated graphics. The sockets are different: Intel uses Socket 2066, AMD uses AM4. The Xeon is marked as end-of-life, while the Ryzen is active. Release dates are 2017-08-28 for Intel and 2020-07-20 for AMD. The Xeon has a launch MSRP of $1113; AMD has no recorded launch MSRP.

The Verdict

The benchmark data favors the AMD Ryzen 7 PRO 4750GE in most scenarios. It wins 7 of 8 head-to-head tests, including all Cinebench runs and Geekbench single-core. The only Intel win, Geekbench multi-core, is large, but it is a single data point. For users whose primary workloads are rendering or single-threaded tasks, the Ryzen is the clear choice. Its 35W TDP and integrated graphics also make it more flexible for system builders.

Intel's Xeon W-2145 is the better option for workloads that align with Geekbench multi-core performance. The 35.5% lead there, combined with quad-channel memory and 48 PCIe lanes, makes it suitable for workstation tasks that require high memory bandwidth or many expansion cards. However, the Xeon is end-of-life, and its 140W TDP is a significant drawback in power-sensitive environments.

Given the data, the AMD Ryzen 7 PRO 4750GE is the more versatile processor for most users. It wins the majority of benchmarks, consumes far less power, and includes integrated graphics. The Intel part retains a niche for specific multi-threaded, bandwidth-heavy applications, but the overall record points to AMD.
