Server chips traditionally offered less single threaded performance than contemporary client parts. Higher core counts translate to less power per core, and the complex interconnect required to connect many cores often suffer from higher latency as well.…

Laptop chips have gotten very powerful in recent years, with increasing CPU core counts, more powerful iGPUs, and higher DRAM bandwidth to feed that compute. All of that creates pressure on the chip’s system level architecture, which must deliver high bandwidth…

Integrated GPUs have become a crucial component in recent laptop chips, thanks to a push for better graphics performance in ultraportable devices. AMD and Intel have both launched impressive iGPU implementations in recent years. Qualcomm’s laptop push needs…

The PC market is one of the toughest areas for a CPU designer to compete in. Consumers in the PC segment expect high performance across a wide range of applications, and famously expect their devices to reach beyond a constrained, curated set of use cases.…

Hello you fine Internet folks, While Arm’s last announcement was about their new datacenter focused CPU, the Arm AGI CPU. Their latest set of announcements bring a much wider focus. The incoming C2-Ultra CPU and G2-Ultra NX GPU IP will see broad use across…

Hello you fine Internet folks,Today we're at Hot Chips 2026! We join IBM to talk about their just revealed Dual-ISA z/ architecture + ARM design with Christian Zoellin, the Core Design Team Leader and Christian Jacobi, the CTO of Systems Development!Hope…

Memory expansion has been attractive for years, and is more relevant than ever because ML models have an insatiable appetite for memory capacity. In response, XCENA has worked with Samsung to create a CXL memory expansion device that can also host SSDs and…

In-memory compute has been an attractive proposition for many years because compute within a memory chip can exploit its higher internal bandwidth. Additionally, in-memory compute avoids the long latency path between DRAM and traditional compute cores. At…

Hello you fine Internet folks,At Hot Chips, Intel talked a bit more about their upcoming Datacenter GPU codenamed Crescent Island. Crescent Island’s party piece is the ultra-high memory capacity curtesy of the LPDDR5X memory subsystem. Making Room for Whales…

Fujitsu’s A64FX was a pivotal core. For the Arm ecosystem, it introduced SVE. SVE continues to define Arm’s vector execution strategy to this day, with newer extensions like SME adopting a similar vector length agnostic approach. For Fujitsu, A64FX marked…

Hello you fine Internet folks, Intel unveiled their upcoming Diamond Rapids Server CPU at Computex where they said that Diamond Rapids has twice the memory bandwidth, PCIe Gen 6, and 50% more cores than Granite Rapids. However, it looks like in the 3 or so…

Hello you fine Internet folks, The RISC-V ecosystem is an ever-evolving one especially in the high-performance application class silicon space. We have seen a number of acquisitions and exits in the past year with Ventana being acquired by Qualcomm in December…

Intel’s Core Ultra series has done well with improving battery life and performance in mobile products. Wildcat Lake, or Core Series 3, aims to take those qualities and bring them into a lower cost product. Wildcat Lake brings in all the new technologies…

CUDA is a giant for GPU compute, which includes machine learning applications. So far, CUDA supports x86-64 and aarch64 CPUs. Now, Nvidia is looking at extending CUDA support to RISC-V. This move opens the door for RISC-V CPUs to feed GPU compute. Nvidia’s…

HBF, or High Bandwidth Flash, uses the same flash memory technology we see in SSDs today. Unlike SSDs, HBF is implemented much like HBM (High Bandwidth Memory). HBF cubes sit on the same package as a compute chip, perhaps even next to HBM. HBF’s idea is to…

HBM, or High Bandwidth Memory, stacks multiple DRAM dies on top of a base die. The dies interface with each other via TSVs, while the base die talks with whatever compute die is using the memory via an interposer. Increasing bandwidth for a new HBM generation…

Hello you fine Internet folks,I did an audio interview with Ravi Subramanian from Synopsys where we talked about the physics that goes into chip design and EDA tools.

Hello you fine Internet folks, NVIDIA has published a 45-page whitepaper explaining Vera, its first server CPU built around the company’s own Olympus core. On paper, Vera is a fascinating chip with an 88-core monolithic compute die, Olympus being a 10-wide…

Arm’s 5-series cores are meant for tasks where performance barely matters, but power and area efficiency are top priorities. Because they’re less performance sensitive, 5-series cores tend to be superseded less often than their more sophisticated counterparts.…

Hello you fine Internet folks, Today we are talking about one of the stranger x86 stories I have seen in a while. According to both SemiAccurate and Reuters, Intel is giving a new startup called RosaicLabs access to the register transfer language code for…
