Broadwell-EP is the common name for Intel’s Broadwell-based Xeon E5 v4 server generation, launched in 2016. Intel’s E5 v4 catalog contains 44 products, spanning different core counts, frequencies, cache sizes, power limits and socket/platform variants. The figures below use Intel’s official specifications and historical Recommended Customer Prices (RCPs), not current used-market prices.
What is Broadwell-EP?
Broadwell-EP refers to the server processors Intel sold primarily as the Xeon Processor E5 v4 Family. “Broadwell” was Intel’s former codename; “EP” is the industry shorthand used for this class of enterprise processors. The family is broader than the dual-socket E5-2600 v4 range, so an E5 v4 family search should not be treated as a single socket class.
Intel placed E5 v3 and E5 v4 in the Grantley and Grantley Refresh platform context. At the platform level, Intel describes DDR4 support up to 2400 MHz, integrated high-bandwidth I/O and Intel Resource Director Technology. Those statements describe the platform generation, not guaranteed support for every motherboard or server.
How large is the Xeon E5 v4 range?
Intel’s family catalog lists 44 E5 v4 products, with model-level launch dates and specifications. Models vary enough that “Broadwell-EP” alone does not identify a processor’s core count, clock speed, cache, thermal design power or system compatibility. Some family members reach 22 cores, while other models prioritize lower power or lower acquisition cost.
#1 Best Overall
- Intel Xeon E5-2699 V4 Docosa-core (22 Core) 2.20 Ghz Processor - Socket Lga 2011-v3 - 5.50 Mb - 55 Mb Cache - 64-bit Processing - 14 Nm - 145 W
For a meaningful comparison, record the exact model number and evaluate these attributes together:
- Physical cores and supported threads
- Base frequency and maximum turbo frequency
- Last-level cache capacity
- Thermal design power (TDP)
- Memory type, speed and population rules on the target system
- Socket, platform and firmware support
- Launch generation and the condition of the particular processor being sold
Two E5 v4 models that show the trade-offs
| Processor | Cores / threads | Base / maximum turbo | Cache | TDP | Process and launch | Intel RCP |
|---|---|---|---|---|---|---|
| Xeon E5-2680 v4 | 14 / 28 | 2.40 GHz / up to 3.30 GHz | 35 MB | 120 W | 14 nm; Q1 2016 | $1,745 |
| Xeon E5-2609 v4 | 8 / 8 | 1.70 GHz / not stated in the cited specification | 20 MB | 85 W | Q1 2016 | $306 |
The E5-2680 v4 combines more cores, higher clocks and more cache with a higher 120 W thermal rating. The E5-2609 v4 has fewer cores and threads, a lower base clock and an 85 W rating. Neither is universally “better”: virtualization density, licensing, latency-sensitive work, cooling capacity and the server’s power envelope determine which compromise is appropriate.
What Broadwell-EP does—and does not—include
Broadwell-EP belongs to the generation before Intel Xeon Scalable processors. Intel’s later Xeon Scalable technical overview identifies features added in that newer platform, including AVX-512, UPI, MPX and sub-NUMA clusters. Those features should not be attributed to E5-2600 v4/Broadwell-EP systems.

The Grantley overview is useful for understanding the broad platform capabilities, but it is not an exhaustive microarchitecture specification and cannot establish the feature set of an individual E5 model or server configuration.
How much did Broadwell-EP Xeons cost?
Intel lists an RCP of $1,745 for the E5-2680 v4 and $306 for the E5-2609 v4. These are Intel’s vendor-recommended customer prices shown on the product specifications, not current retail quotations, auction results or used-processor averages. Intel notes that point-of-sale pricing can vary with factors such as local tariffs and taxes and may change.
A secondhand listing cannot be compared with those historical figures without checking whether the chip is tested, whether a heatsink is included, the seller’s location, lot size, return terms and the processor’s condition. No current market price should be inferred from Intel’s RCP.

How to check compatibility before buying an E5 v4 CPU
A Broadwell-EP processor is only an upgrade if the complete server platform supports that exact part. Use this checklist before ordering:
- Identify the exact system: record the motherboard or server model, board revision and socket arrangement.
- Read the vendor CPU list: use the system manufacturer’s documentation for supported E5 v3/v4 models and any restrictions on single- or dual-socket operation.
- Verify firmware: check the required BIOS, UEFI, management-controller or other firmware revision. Update only through the vendor’s documented process.
- Confirm platform and chipset support: a family-level Grantley description does not prove that a particular board accepts every E5 v4 processor.
- Check memory rules: verify DDR4 type, supported speed, rank restrictions and the required DIMM population for one or two CPUs. The platform-level ceiling of up to 2400 MHz may be lower in a specific configuration.
- Match cooling and power: ensure the heatsink, airflow, VRMs and power supplies can handle the selected model’s TDP, especially when moving from an 85 W part to a 120 W part.
- Assess the seller’s condition claims: ask whether the processor is tested, pulled from a working system, marked engineering-sample or retail, and covered by a return policy.
- Check the complete configuration: dual-socket systems may require matched processors, and memory, firmware and licensing limits can affect the practical value of an upgrade.
How to choose among E5 v4 models
Choose for throughput
Higher-core models can improve heavily parallel virtual-machine, container, rendering and batch workloads, provided the software licensing and memory bandwidth justify them. Compare cores and threads with the application’s scaling behavior instead of selecting by model number alone.
Choose for per-thread responsiveness
Base and turbo frequencies matter more for lightly threaded services and interactive tasks. Confirm the exact maximum turbo specification for the model under consideration; it is not safe to assume that every E5 v4 part reaches the same clock.
Rank #4

Choose for a constrained thermal envelope
Lower-TDP models can simplify cooling and power planning, but they may also trade away frequency, cache or threads. The E5-2609 v4’s 85 W rating illustrates this type of compromise.
Choose for an existing server
Start with the server vendor’s supported-CPU list and firmware requirements, then compare models that are actually validated for that chassis. A nominally compatible socket is not sufficient evidence.
Where Broadwell-EP fits historically
Intel’s 2016 launch positioned the E5-2600 v4 family for cloud and software-defined infrastructure. Diane Bryant, then Intel’s senior vice president and general manager of the Data Center Group, said: “Enterprises want to benefit from the efficiency and agility of cloud architecture and on their own terms – using the public cloud offerings, deploying their own private cloud, or both.”
Today, the practical question is less about the launch label and more about whether an inexpensive, tested E5 v4 processor fits an already-owned Grantley server. New deployments should account for the platform’s age, firmware availability, power use and the absence of later-generation features.

The Bottom Line
Broadwell-EP is a broad Xeon E5 v4 family, not one uniform chip. Use the exact model’s core, clock, cache and TDP data, treat Intel’s RCP as historical guidance, and verify the server, BIOS, memory and cooling requirements before buying.
