Core
What is it?
It used to be that a single CPU (central processing unit) possessed a single core—the processing unit within the CPU that receives and executes instructions. Times have changed, however, and now a single CPU can house a multitude of cores, each capable of carrying out its own set of instructions. The cores themselves may contain even smaller threads—the smallest sequence of instructions that can be executed independently. The upshot of all this is that modern CPUs can carry out multiple tasks simultaneously thanks to their high core and thread counts. You can envision it as a multi-lane highway; rather than making the cars go faster on a single lane, the use of cores opens up multiple lanes on the same road for many instructions to be executed at the same time.
Why do you need it?
Almost all modern processors are based on the multi-core architecture. The inclusion of more cores not only means more tasks can be completed simultaneously, which eliminates bottlenecks and accelerates computation, it also opens the door to innovative computing techniques such as parallel computing and distributed computing. High performance computing (HPC), which is a major trend in advanced computing, also relies heavily on linking multiple servers running multi-core processors to form a computing cluster that calculates on the scale of supercomputers.
How is GIGABYTE helpful?
GIGABYTE servers are powered by the most advanced processors. For example, if you installed dual 64-core AMD EPYC™ CPUs in each node of GIGABYTE's H262 Series of High Density Servers, and then populated a full 42U (42 rack units) server rack with these servers (leaving some room for networking equipment), you would have as many as 10,240 cores in one rack. Another kind of processor that is rapidly gaining ground is based on the ARM architecture, which can house as many as 128 cores in a single CPU. The excellent power efficiency of ARM processors goes a long way towards reducing power consumption and resolving heat-related issues.

To Harness Generative AI, You Must Learn About “Training” & “Inference”
Unless you’ve been living under a rock, you must be familiar with the “magic” of generative AI: how chatbots like ChatGPT can compose anything from love letters to sonnets, and how text-to-image models like Stable Diffusion can render art based on text prompts. The truth is, generative AI is not only easy to make sense of, but also a cinch to work with. In our latest Tech Guide, we dissect the “training” and “inference” processes behind generative AI, and we recommend total solutions from GIGABYTE Technology that’ll enable you to harness its full potential.

0 to 100 KPH in 3.3 Seconds! NTHU Builds Electric Formula Student Race Cars with GIGABYTE
Representing Hsinchu’s Tsing Hua University, NTHU Racing is one of Taiwan’s top Formula Student racing teams. In 2019, its electric formula student race car, the “TH04”, took second place in Formula SAE Japan. In August of 2022, its new and improved, 100% manufactured in Taiwan “TH06” raced for the gold in Formula Student Germany. Tsing Hua University built the “TH06” using GIGABYTE Technology’s W771-Z00 and W331-Z00 Tower Server/Workstation products. From finite element analysis (FEA) and computational fluid dynamics (CFD) modelling and analysis during the design phase, to racing simulations and experimenting with new tech during the testing phase, GIGABYTE servers provided NTHU Racing with the processing power and versatility it needed to engineer a high-performing electric vehicle that can go from 0 to 100 kph in 3.3 seconds—almost on par with Tesla’s Model S, which can go from 0 to 60 mph in 2.6 seconds.

Japanese Telco Leader KDDI Invents Immersion Cooling Small Data Center with GIGABYTE
Japanese telco giant KDDI Corporation has invented a new class of data centers that are mobile and eco-friendly. These “container-type immersion cooling small data centers” employ “single-phase immersion cooling” to reduce power consumption by 43% and lower the PUE below 1.07. GIGABYTE Technology drew from its years of experience in the telco sector to provide the R282-Z93 and R182-Z91 Rack Servers for KDDI to use as the management and GPU computing nodes in the data center. KDDI benefits from the servers’ powerful 3rd Gen AMD EPYC™ CPUs, the scalable, high-density configuration of NVIDIA® GPUs in small form factors, and the servers’ optimized compatibility with the liquid-based data center cooling solution. GIGABYTE’s participation in KDDI’s project is in line with GIGABYTE’s long-term CSR and ESG efforts, which are focused on working with global industry leaders to “Upgrade Your Life” with high tech while building a greener, more sustainable environment for our future.
