Intel Xeon E5-1620 v4

The Intel Xeon E5-1620 v4 is a 4-core, 8-thread desktop processor built on the Broadwell-EP architecture, released in June 2016. It operates at a base clock of 3.50 GHz and a boost clock of 3.80 GHz, with a 10 MB shared L3 cache and a 140 W TDP. This analysis examines its benchmark positioning, workload suitability, and platform characteristics based strictly on the provided data.

Benchmark Performance

The average benchmark score for the Xeon E5-1620 v4 is 1812, placing it at the 44th percentile among all CPUs tracked. This position indicates it sits just below the median performer, a result consistent with its 4-core/8-thread configuration competing in a landscape dominated by higher-core-count parts. In Cinebench R23, the processor scores 6265 in multi-core and 884 in single-core tests, while in Cinebench R20 it achieves 2631 multi-core and 371 single-core. The older Cinebench R15 results show 631 multi-core and 89 single-core, reflecting the scaling of the workload across versions.

Compared to its nearest rivals, the E5-1620 v4 shows remarkably tight clustering. It is 0.2% ahead of the Intel Core i3-9320, which scores 1808, and 0.4% ahead of the AMD Ryzen 3 1300X, which scores 1805. Against the Intel Xeon E5-1630 v3, the E5-1620 v4 trails by 0.5%, with the rival scoring 1821. The gap widens slightly against the Intel Xeon D-1537, which leads by 1% with a score of 1830. These deltas are negligible in real-world terms—sub-1% differences fall within typical run-to-run variance for most benchmark suites.

The single-core results tell a more interesting story. The Cinebench R23 single-core score of 884, when compared to the multi-core score of 6265, yields a ratio of roughly 7.1:1. This indicates that the processor achieves only modest scaling beyond its four physical cores, which is expected given that hyper-threading typically adds 20-30% throughput rather than doubling it. The boost clock of 3.80 GHz provides a 0.30 GHz uplift over the base clock, which helps single-threaded performance but does not compensate for the low core count in heavily parallel workloads.

Who Should Consider It

Benchmark results indicate this processor is suited for workloads that rely on moderate multi-threading with strong single-thread responsiveness. The Cinebench R23 multi-core score of 6265 places it in the lower-middle range of desktop CPUs, meaning it can handle everyday productivity tasks such as office suites, web browsing, and light content creation without significant bottlenecks. However, for demanding 3D rendering or video encoding that scales across many cores, the 4-core/8-thread design will be a limiting factor.

For gaming, the single-core score of 884 in Cinebench R23 is the more relevant metric, as most games prioritize single-thread performance. The 3.80 GHz boost clock provides adequate headroom for older or less demanding titles, but modern games that utilize 8 or more threads will likely show performance limitations. The 44th percentile overall ranking reinforces that this is not a high-end gaming processor by current standards.

Content creators working with light workloads—such as photo editing or 2D design—may find the E5-1620 v4 acceptable, particularly given its ECC memory support, which is valuable for data integrity in professional environments. The 76.8 GB/s memory bandwidth from quad-channel DDR4 also benefits memory-sensitive applications. Conversely, users running heavy compilation, scientific simulation, or 3D animation workloads should look elsewhere, as the multi-core scores indicate clear scaling limitations compared to higher-core-count alternatives.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance reveals a processor optimized for responsiveness over raw throughput. The Cinebench R23 single-core score of 884 represents 14.1% of the multi-core score of 6265, which is a typical ratio for a 4-core/8-thread part. In Cinebench R20, the single-core score of 371 is 14.1% of the multi-core score of 2631, showing consistent scaling across benchmark versions.

This behavior means that tasks which are latency-bound—such as opening applications, scrolling through documents, or executing macro-enabled spreadsheets—will feel snappy due to the 3.80 GHz boost clock. However, tasks that spawn many threads, such as batch image processing or multi-stream video playback, will not gain proportionally. The 8 threads provide a modest improvement over a true 4-core processor, but the lack of additional physical cores limits the ceiling for parallel efficiency.

The data suggests that the E5-1620 v4 behaves like a high-clocked quad-core with hyper-threading, rather than a workstation part designed for heavy throughput. Its single-thread performance is adequate for its era, but its multi-thread performance lags behind modern 6-core and 8-core processors that are now common in similar price tiers.

FAQ

How It Compares

Intel Core i3-9320: The E5-1620 v4 leads by a marginal 0.2% in average score (1812 vs 1808). Both are 4-core/8-thread parts, but the Xeon offers quad-channel memory and ECC support, while the i3 targets mainstream desktops with dual-channel memory. The performance difference is negligible, making platform features the deciding factor.

AMD Ryzen 3 1300X: The Xeon is 0.4% ahead (1812 vs 1805). The Ryzen 3 1300X is a 4-core/4-thread processor, so the Xeon’s 8 threads give it a small advantage in multi-threaded tasks, reflected in the slightly higher score. However, the Ryzen parts typically offer lower power consumption and a more modern platform.

Intel Xeon E5-1630 v3: The E5-1620 v4 trails by 0.5% (1812 vs 1821). The E5-1630 v3 is based on the Haswell-EP architecture, which is one generation older but features a slightly higher average score. This suggests that the clock speed and architecture refinements of the v4 are offset by other factors, resulting in near-parity.

Intel Xeon D-1537: The E5-1620 v4 is 1% behind (1812 vs 1830). The Xeon D-1537 is a 16-thread part (8 cores) with a lower clock speed, but its higher core count gives it an edge in multi-threaded workloads. The E5-1620 v4 compensates with higher single-thread performance, but the average score favors the D-1537.

Platform and Compatibility

The E5-1620 v4 uses the Intel Socket 2011-3, which is a high-end desktop and server platform. It supports quad-channel DDR4 memory with a peak bandwidth of 76.8 GB/s and includes ECC memory support, which is uncommon in consumer desktop parts. The processor provides 40 PCIe Gen 3 lanes from the CPU, enabling multiple graphics cards or high-speed storage devices without relying on the chipset for additional lanes.

The 14 nm process node and Broadwell-EP architecture are shared with other Xeon E5 v4 parts, meaning the platform supports a wide range of processors from the same generation. However, because the processor is end-of-life, upgrade paths are limited to used or refurbished parts on the same socket. The 140 W TDP requires a capable air or liquid cooler, and the locked multiplier prevents overclocking, so cooling requirements are moderate but not extreme.

The launch MSRP was $294, which positioned it as an entry-level Xeon for desktop workstations. The platform’s quad-channel memory and 40 PCIe lanes are its primary differentiators from consumer platforms, making it suitable for users who need ECC memory or extensive expansion capability. However, the 4-core/8-thread configuration is modest by modern standards, and the end-of-life status means users should weigh the platform benefits against the availability of newer, higher-core-count alternatives.
