Intel Xeon Gold 6148 vs 6140: Specification Differences & Performance

Intel Xeon Gold 6148 vs 6140

Intel, as we all are aware is arguably one of the best semiconductor companies in the world with top of the line processors for laptops and desktops. The Xeon ranges of processors manufactured by Intel are designed for non-consumer, server-side applications. Some examples of its apps may include workstations, servers and embedded systems. The series was first introduced back in 1998. In today’s post, we have compared to the two most capable processors (Intel Xeon Gold 6148 vs 6140) in the Xeon range of microprocessors and find the similarities and differences between them.

Intel Xeon Gold 6148 vs 6140: The Comparison

Well, the nomenclature itself should give it out. The Intel Xeon Gold 6148 is a lightly higher regarding specifications as compared to the Xeon Gold 6140. Let us check out each of them under separate heads.

Intel Xeon Gold 6148 – An Overview

The Intel Xeon 6148 does come with 20 cores and with an excellent clock speed of 2.4 GHz. The processor supports a clock speed of 2670 MHz and thus offers you an outstanding faster memory performance. You may look ahead for a better system performance with this speed. The microprocessor would provide you with high performance with its A higher 40 CPU threads for an enhanced better multitasking functionality.

The Intel Xeon Gold 6148 uses the optimized 14nm lithography process. The new technology helps in creating a smaller die-size of chip offering you better performance. The larger L2 cache on the processor provides an efficient and faster CPU and system-wide performance. You have 20 MB L2 Cache with the processor.

The processor supports up to 64-bit architecture and thus should be the best option for enhanced performance. It will also let you run the 64-bit applications with ease. The 3.7 GHz enhanced turbo clock speed has a capacity of increased performance. The dynamic frequency scaling is a feature that should allow you to conserve power and reduce noise.

The Intel Xeon Gold 6148 offers you a six-channel memory for an improved data transfer performance. Moreover, you also have access to hardware-assisted virtualization. This will provide you with better performance.

Intel Xeon Gold 6140 – An Overview

Slightly lower number of 18 cores at 2.3 GHz would make it somewhat inferior to the Intel Core 6148. The RAM speed is precisely at 2670 MHz putting at par with the sibling. The CPU threads measure at 36 and should be capable of enough level of multitasking.

Regarding the technology used in the manufacture of the processors, it remains the same as with the Intel Xeon Gold 6148. However, the L2 Cache is slightly lower at 18 MB. There is support for 64 bit operating systems and applications. It also has a 3.7 GHz turbo clock speed ensuring better performance.

Other features like some memory channels and hardware supported virtualization remain similar as on the Xeon Gold 6148 processor.

A Tabulated Comparison between the Two Processors

A tabular form of comparison would be helpful in understanding the similarities and differences between the two processors for Intel in lower and better manner. The side by side comparison can be much help in understanding the concepts in a better way.

From the side by side comparison as can be seen from above compilation, it can be understood that both the processors are almost equivalent in most aspects with just a few slighter variations. They should be capable of being used interchangeably for your applications except in cases where you have a few specific requirements that would necessitate the use of Intel 6148 processor.

Advantages of each of the processors over the other

Here are the benefits that the Intel Xeon Gold 6140 can be summed up as

  • It offers you a better power consumption in comparison to the Intel 6140
  • The prices are around 20 percent lower.

In contrast, the Intel Xeon 6148 has the following advantages

  • More cores would mean more processing power. This will improve your multitasking capabilities.
  • The higher base frequency ensures that you would be able to run the multi-threaded applications quite faster.

The Pros and Cons of Each Processor

As with any other processors or components, both Intel 6148 and 6140 have their own set of pros and cons. Let us check out the positives and drawbacks of each of them separately for a proper understanding.

Pros for Intel Xeon Gold 6148

  • A higher number of cores translate into better performance
  • Can handle multiple cores simultaneously

Cons for Intel Xeon Gold 6140

  • A little expensive
  • Higher power consumption

Pros for Intel Xeon 6140

  • The power consumption should be what would make it an excellent functionality
  • The lower price point should make it an attractive option for affordable systems

Cons for Xeon 6140

  • A lesser number of cores
