NVIDIA throws Intel a $5 billion lifeline to build PC and data center CPUs

engadget.com Unknown 2025-09-23 02:20:30

NVIDIA has today announced it will invest $5 billion in Intel as part of a new collaboration between the two companies. In a statement, NVIDIA said it would work with its ailing rival to “jointly develop multiple generations of custom data center and PC products.” The partnership will focus on "seamlessly integrating" NVIDIA's class-leading GPUs and AI chips with Intel's ailing x86 CPUs. Some of that work will be based on harnessing NVLink, NVIDIA's existing system to marry-up x86 CPUs with its

Weird CPU architectures, the MOV only CPU (2020)

news.ycombinator.com Unknown 2025-09-26 02:46:46

I like CPU architectures, especially weird, interesting and unusual ones. For example, the Intel iAPX 432 is still something I would love to play around with. Recently, I realized that a working CPU can be made with just a simple Move instruction. For this to work, everything needs to be memory mapped. The ALU, program counter, everything. Of course, this idea is nothing new and this idea is called the Transport Triggered Architecture. I decided to have a look into this, how it works and make a

CPU Utilization is Wrong (2017)

news.ycombinator.com Unknown 2025-10-03 08:06:39

The metric we all use for CPU utilization is deeply misleading, and getting worse every year. What is CPU utilization? How busy your processors are? No, that's not what it measures. Yes, I'm talking about the "%CPU" metric used everywhere, by everyone. In every performance monitoring product. In top(1). What you may think 90% CPU utilization means: What it might really mean: Stalled means the processor was not making forward progress with instructions, and usually happens because it is waitin

The Intel 285K CPU in my high-end 2025 Linux PC died again! 😡 Notably, this was the replacement CPU for the original 285K that died in March, and after reading through the reviews of Intel CPUs on my electronics store of choice, many of which (!) mention CPU replacements, I am getting the impression that Intel’s current CPUs just are not stable 😞.

%CPU utilization is a lie

news.ycombinator.com Brendan Long 2025-10-18 10:01:02

I deal with a lot of servers at work, and one thing everyone wants to know about their servers is how close they are to being at max utilization. It should be easy, right? Just pull up top or another system monitor tool, look at network, memory and CPU utilization, and whichever one is the highest tells you how close you are to the limits. And yet, whenever people actually try to project these numbers, they find that CPU utilization doesn't quite increase linearly. But how bad could it possibly

Like Intel before it, AMD blames motherboard makers for burnt-out CPUs

news.ycombinator.com Unknown 2025-10-24 10:54:42

AMD's X3D-series Ryzen chips have become popular with PC gamers because games in particular happen to benefit disproportionately from the chips' extra 64MB of L3 cache memory. But that extra memory occasionally comes with extra headaches. Not long after they were released earlier this year, some early adopters started having problems with their CPUs, ranging from failure to boot to actual physical scorching and burnout—the problems were particularly common for users of the 9800X3D processor in A

GMP damaging Zen 5 CPUs? Background We have fried two Ryzen 9950X CPUs in a few months by running GMP tests. This is not expected, of course. In this page, we provide as much information as possible to help analysing the problem. What causes these CPUs to die while running GMP is unknown to us. While similar, it is not the widely reported Asrock motherboard problem, as the motherboards we use are of a different make (see below).

Acronis True Image costs performance when not used

Over two years ago I installed Acronis True Image for Crucial in order to migrate my data to a new SSD I had just purchased. It worked. I then left True Image installed “just in case”, and what harm could that possibly cause. Well, funny you should ask.

Linux Address Space Isolation Revived After Lowering 70% Performance Hit to 13%

Several years ago Google engineers began exploring address space isolation for the Linux kernel and ultimately proposing Linux ASI for better dealing with CPU speculative execution attacks . While the hope was it would better cope with the ever growing list of CPU speculative execution vulnerabilities, the effort was thwarted initially by I/O throughput seeing a 70% performance hit . That level of performance cost was unsustainable. But now that I/O overhead has been reduced to just 13%.Google e
