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…

Hello you fine Internet folks, Today we are over AMD's Advancing AI 2026 event to chit chat on their newly revealed CDNA5 architecture with Alan Smith! AMD's Corporate Fellow and Chief Architect for Datacenter GPUs. Hope y'all enjoy! The transcript below…

Hello you fine Internet folks, here at AMD’s Advancing AI event we are looking at AMD’s brand new Instinct MI455X, replacing the older Instinct MI355X at the top of their AI stack. It is AMD’s first GPU designed for rack-scale AI deployments and is based…

Hello you fine Internet folks, this article is a sequel to the Scrying the AMD GFX1250 LLVM Tea Leaves article where we are going to look at the differences between GFX1250 and GFX1251. So if you want to know what GFX1250 is changing compared to the prior…

In just a few short days, AMD will be showing off their brand new MI400 series of Datacenter Accelerators at their Advancing AI event but before that event comes, we thought it would be fun to attempt to scry the tea leaves that are LLVM commits to see what…

CPU designs must evolve to keep up with changing workloads. Sometimes, that evolution involves extending the instruction set to efficiently represent certain types of work. Intel’s AMX extension is one such example. AMX accelerates matrix multiplication for…
