Difference Between Qualcomm Krait and Nvidia Epyc (With Table)

Every day, a slew of new technologies make their way onto the market. These technologies are designed to assist humans and make their lives easier by keeping them up-to-date. Every day, new functions are added to mobile phones, PCs, and laptops. Mobile phones’ speed and performance are determined by the processor.

Qualcomm Krait vs Nvidia Epyc

The main difference between Qualcomm krait and Nvidia Epyc is that Qualcomm krait is an ARM-based central processing unit (CPU) with Snapdragon S4 support. Nvidia Epyc, on the other hand, is a multi-core x86-64 microprocessor created and sold by AMD under the Zen microarchitecture.

The Qualcomm Krait is classified as an ARM-based processor (Central Processing Unit). It is compatible with the Snapdragon S4 processor. It belongs to the Snapdragon model series of SoCs. In the year 2012, this processor was released. The scorpion CPU was succeeded by this one. The scorpion CPU has several architectural features with this chip.

The Nvidia Epyc is a CPU designed and sold by AMD (Advanced Micro Devices Inc.). It is based on the Zen microarchitecture of the firm. The ADM’s Zen is the code name for a family of computer microarchitectures. In the year 2017, it was initially released. This CPU was primarily aimed at the server and embedded system industries.

What is Qualcomm Krait?

The Qualcomm krait is a processor that was introduced in 2012. This is a Central Processing Unit (CPU) based on the ARM architecture (CPU). The American Multinational Corporation (Qualcomm) is a multinational corporation based in the United States (AMC). Delaware operates Qualcomm’s main headquarters, which is located in San Diego, California.

Qualcomm is an American firm that makes wireless technology such as semiconductors, software, and services. Irwin M. Jacobs and six other co-founders created this Qualcomm corporation in 1985. It holds patents for mobile communication protocols such as 4G, 5G, CDMA2000, TD-SCDMA, and WCDMA.

The Qualcomm Krait’s performance, or CPU clock rate, ranges from 1 GHz to 2.7 GHz. Qualcomm Krait’s computer architecture and classification are ARMv 7-A and Thumb-2. It is a multi-core processor with two or more distinct processing units called cores in a single interconnected circuit.

What is Nvidia Epyc?

Nvidia Epyc is a multi-core x86-64 microprocessor from Nvidia. It was first released in the year 2017. The microarchitecture of this CPU is identical to that of its desktop-grade counterparts. It has a lot of features, such as a lot of cores, a lot of PCI express lanes, a lot of RAM support, and a lot of cache memory. Because of the Infinity fabric inter-chip interface, it is compatible with multi-chip and dual-socket systems.

The clock speed of the CPU ranges from 2.7 GHz to 4.1 GHz. Each server chip has eight memory channels and one hundred and eight PCIe 3.0 lanes. The infinity fabric, which is deployed in a dual-processor arrangement, uses 64 of the 128 lanes for CPU-to-CPU communication.

It is the Opteron’s descendant. It was AMD’s x86 former server and workstation processor line, and it was the first to use the AMD64 instruction set architecture. The core names of the Nvidia Epyc are, for example, Rome, Milan, Genoa, and Bergamo. In 2018, the second-generation Epyc (Rome) was released. In the year 2019, the third generation Eypc (Milan) was released.

There is also a Chinese edition, which was developed specifically for the Chinese server market and produced by the AMD-Chinese joint venture. It is a collaboration between the semiconductor business Advanced Micro Device (AMD) and a Chinese firm. Zen, Zen2, Zen3, and Zen4 are examples of microarchitecture.

Main Differences Between Qualcomm Krait and Nvidia Epyc

  1. The Qualcomm Krait was introduced in 2012, whilst the Nvidia Epyc was introduced in June of 2017.
  2. The Qualcomm Krait was produced by Qualcomm, whilst the Nvidia Epyc was produced by worldwide foundries.
  3. The Qualcomm Krait is an ARM-based processor, whereas the Nvidia Epyc is a multi-core x86-64 microprocessor.
  4. The Qualcomm Krait’s CPU block rate ranges from 1 GHz to 2.7 GHz. The Nvidia Epyc, on the other hand, has a maximum CPU clock rate of 2.7 GHz to 4.1 GHz.
  5. The Qualcomm Krait has a scorpion-like precursor, while the Nvidia Epyc has an Opteron-like predecessor.


Both the Qualcomm Krait and the Nvidia Epyc processors have their own set of benefits and drawbacks. They’re both made by Qualcomm and Nvidia, two well-known firms that have developed diverse services and technology. They both have a significant market impact.

The Qualcomm Corporation was created in 1985, while Nvidia Corporation was founded on April 5, 1993, about 28 years ago. Qualcomm is a company that makes telecom equipment and works in the semiconductor business. Nvidia’s products include semiconductors, artificial intelligence, GPUs, graphics cards, electronic goods, games consoles, as well as other computer hardware.

Irwin Jacobs and Andrew Viterbi established Qualcomm. Jensen Huang, Curtis Priem, and Chris Malachowsly founded Nvidia. They are both served in every corner of the world, i.e., globally. Nvidia manufactures graphics processing units, central processing units, chipsets, drivers, tablets, TV accessories, laptops, and data processing units.

They have both put in a lot of effort to upgrade and introduce the best technologies in the world to human usage, as well as other essential applications around the world. Many people confuse Qualcomm Krait and Nvidia Epyc, assuming they are the same thing because they are both American-based companies. However, they are not, as they differ in many ways, including features, processing power, and other factors.
