About This Product
Overview
The Intel Xeon Gold 6148 is a server processor built for LGA3647 platforms and is well suited to environments that need dependable multi-core processing. With 20 cores and 40 threads, it is designed to handle demanding workloads that benefit from parallel execution, including virtualization, database tasks, application hosting, and general enterprise server use. Its 2.40GHz base clock and 3.70GHz turbo clock provide a balanced mix of steady throughput and responsive performance when workloads increase. The 27.5MB Smart Cache helps support efficient data access, while DDR4-2666 memory support and PCIe 3.0 compatibility make it a practical fit for modern server architectures. This processor is also noted as compatible with Dell R640, R740, and R840 systems, making it a useful option for targeted server upgrades or replacements.
Performance & Scalability
For businesses and IT teams looking to maintain or expand server capacity, the Xeon Gold 6148 offers a strong foundation for scalable compute performance. The 20-core, 40-thread design helps distribute workloads across multiple processes, which can be valuable in virtualized environments and other multi-user deployments. The 150W TDP is an important consideration for system planning, especially in chassis where thermal and power budgets must be managed carefully. Support for DDR4-2666 memory allows the processor to work with server memory configurations designed for stable operation, while PCIe 3.0 support provides connectivity for compatible expansion devices and storage controllers. In systems built around the LGA3647 socket, this CPU can help support consistent performance across a range of enterprise workloads without requiring a platform change.
Storage Flexibility
Although this is a processor rather than a storage device, its platform support can influence overall storage performance and system flexibility. PCIe 3.0 compatibility allows supported systems to connect with a variety of expansion cards that may be used for storage or I/O functions, depending on the server configuration. When paired with compatible Dell R640, R740, or R840 hardware, the Xeon Gold 6148 can be part of a server build that supports efficient data handling and responsive access to attached resources. The processor’s cache and memory support also contribute to smoother operation in workloads that rely on frequent data movement between CPU, memory, and storage subsystems.
Why Choose This Product?
The Intel Xeon Gold 6148 is a practical choice for organizations that need a compatible replacement or upgrade CPU for supported LGA3647 servers. Its combination of 20 cores, 40 threads, DDR4-2666 memory support, and PCIe 3.0 compatibility makes it suitable for a wide range of enterprise tasks where reliability and multi-threaded performance matter. Because it is identified for use with Dell R640, R740, and R840 systems, it is especially useful for maintaining existing infrastructure with a processor that matches the platform requirements. For IT hardware buyers seeking a server CPU with clear compatibility and established specifications, this model offers a straightforward option for keeping supported systems in service.
About this processor
Intel Xeon Gold 6148, a 20 core, 40 thread LGA3647 processor at 2.40GHz with 3.70GHz turbo, for Dell R640, R740 and R840. Tested and stocked in Doha, delivered across Qatar within a day.
The Xeon Gold 6148 is the faster twenty core of Intel's first generation Xeon Scalable Gold series: the same 20 cores, 40 threads and 27.5MB cache as the 6138, but a 2.40GHz base instead of 2.00GHz, at a 150W rating in the LGA3647 socket. It supports six channels of DDR4-2666 and PCIe 3.0, and is named as compatible with the Dell PowerEdge R640, R740 and R840. It was the processor of choice for high performance computing clusters of its generation.
Buyers in Qatar fit the refurbished 6148 to 14th generation Dell servers and Precision workstations that need both core count and clock, such as simulation, rendering and analytics nodes. ServerDove keeps it in Doha stock and fits it to its own Precision workstations.

Part numbers and identification
Buyers search for "Xeon Gold 6148", "6148 CPU" and "Gold 6148 20 core".

| Model | Intel Xeon Gold 6148 |
| Family | Xeon Scalable, first generation, Gold 6100 series |
Specification
The extra 400MHz of base clock over the 6138 costs 25W, so the 6148 needs the high performance heatsink in a 1U chassis where the 6138 uses the standard one.
| Cores | 20 |
| Threads | 40 |
| Base clock | 2.40GHz |
| Turbo clock | 3.70GHz |
| Smart Cache | 27.5MB |
| Socket | LGA3647 |
| TDP | 150W |
| Memory support | DDR4-2666, six channels |
| PCIe | PCIe 3.0, 48 lanes |
Forty threads with a 2.40GHz base is a strong combination for simulation, rendering and analytics, where both parallel throughput and per thread speed matter. Two per server gives 80 threads at 2.40GHz, and the 27.5MB cache per processor keeps large working sets close to the cores.
Compatible servers
Dell models named for the 6148 are listed; it fits any first or second generation Xeon Scalable server that supports 150W processors.
| Server | Generation | Note |
|---|---|---|
| Dell PowerEdge R640 | 14th generation | Needs the high performance heatsink |
| Dell PowerEdge R740 | 14th generation | Standard 2U cooling is sufficient |
| Dell PowerEdge R840 | 14th generation | Fit four identical processors |
Installation
Assemble the processor into its carrier and onto a 150W rated heatsink, lower the assembly onto the LGA3647 socket and tighten the screws in the numbered order. No firmware update is needed on a first generation server. Check the chassis fan configuration: Dell specifies additional fans for 150W processors in some 1U configurations. Pair only with another 6148 and fill all six memory channels per socket.
