Raytracing on Meteor Lake’s iGPU
Meteor Lake iGPU is a testament to Intel’s mobile graphics aspirations. It’s almost a quarter of an Arc A770. The Xe-LPG architecture used in Meteor Lake inherits Xe-HPG (A770) traits, including hardware raytracing. Here I’ll note a few observations on Intel’s raytracing implementation, using…
Intel’s Ambitious Meteor Lake iGPU
Intel and AMD both tried to ship iGPUs fast enough to compete with low end discrete cards over the past 10 years with mixed results. Recently though, powerful iGPUs have been thrown back into the spotlight. Handhelds like Valve’s Steam Deck and ASUS’s ROG…
Inside Control Data Corporation’s CDC 6600
Computers fill essential roles in modern, growing economies. Banks, airlines, and other large business have used computers to efficiently handle large amounts of data. As these businesses grow and cope with ever larger datasets, their compute needs will only increase. Control Data Corporation (CDC)…
Why x86 Doesn’t Need to Die
Hackaday recently published an article titled “Why x86 Needs to Die” – the latest addition in a long-running RISC vs CISC debate. Rather than x86 needing to die, I believe the RISC vs CISC debate needs to die. It should’ve died a long time…
The Nerfed FPU in PS5’s Zen 2 Cores
Fritzchens Fritz’s awesome die photos revealed that the Playstation 5’s Zen 2 cores spend less die area on their FPUs than their desktop cousins. Thanks to Brutus, I got to take a closer look at just how AMD got Zen 2’s FPU to drop…
Loongson 3A6000: A Star among Chinese CPUs
Computing power has emerged as a vital resource for economies around the world. China is no exception, and the country has invested heavily into domestic CPU capabilities. Loongson is at the forefront of that effort. We previously covered the company’s 3A5000 CPU, a quad…
Inside Snapdragon 8+ Gen 1’s iGPU: Adreno Gets Big
Mobile SoCs have come a long way over the past eight years. I previously covered the Adreno 530 in Qualcomm’s Snapdragon 821, which had to do its best within a tiny power and thermal envelope using a now outdated 14 nm process. Now I’m…
Ryzen Z1’s Tiny iGPU
Editor’s Note: Just like our prior Ryzen Z1 article, the ROG Ally was kindly provided by Asus to let us test the Ryzen Z1. ASUS ROG Ally comes in two configurations: AMD’s Ryzen Z1 Extreme and the Ryzen Z1. The Ryzen Z1 Extreme uses…
LLVM’s Ampere1B Commit
Ampere Computing found a niche in creating ARM-based server CPUs. Ampere Altra saw service in Oracle Cloud, Google Cloud, and Microsoft Azure. For Altra, Ampere used Arm Ltd’s Neoverse N1 core design. Using an existing core design saves engineering time and lets the company…
AMD’s Mild Hybrid Strategy: Ryzen Z1 in ASUS’s ROG Ally
Editor’s Note: ASUS sent us the ROG Ally sample – our first review sample from a company – in order to test the Ryzen Z1 SOC inside the device. So a massive thank you to them! CPUs with hybrid core configurations have become mainstream…
