Engineering samples of AMD's upcoming EPYC Zen 6 datacenter CPUs, codenamed Venice, have cropped up online. Uncovered by Olrak29_ on X, six different test results were published on OpenBenchmark.org, including some CPU specifications._

Sample 100-000001056-09 was tested on the Kenya platform featuring 128 cores, four CCDs, and two IODs. Lastly, three samples were tested on the Nigeria platform featuring two CPUs per setup. Sample 100-0002138-02 featuring 64 cores, two CCDs, two IODs, sample 100-000001056-03 featuring 128 cores, four CCDs, two IODs, and sample 100-000001051-08 featuring 192 cores with eight CCDs and two IODs.

The CCD count of all the aforementioned samples reveals that these chips use likely use Zen 6c cores and come with higher-density CCDs compared to Zen 5. The 64-core and 128-core models come with 32 cores per CCD, while the 192-core trims use 24 cores per CCD. These numbers back up previous reports of Zen 6 improving the number of cores available on each CCD. AMD has yet to detail Zen 6 CCDs, but rumors suggest they'll come with up to 12 Zen 6 cores. Regardless, there's a high likelihood that space-optimized Zen 6c cores are at play here.
Unfortunately, some of the Openbenchmark listings are no longer available, but we were able to get clock speeds for one of the 64-core chips, which peaked at 3.54GHz.
Zen 6 is AMD's next-generation CPU architecture set to release in 2027, featuring up to 256 cores for the flagship datacenter parts. Venice will run on AMD's upcoming SP7 socket and feature significant improvements to memory bandwidth compared to Turin. One of the architecture's highlights is the jump in core count for both Zen 6 and Zen 6c. Zen 6 cores will reportedly be housed in 12-core CCDs, and Zen 6c cores will be housed in 32-core CCDs, respectively. AMD is also allegedly boosting L3 cache capacity to 48MB for Zen as well.
We've yet to hear any official news about Zen 6 in consumer platforms, codenamed Olympic Ridge. In generations past, AMD would introduce its consumer range before turning its attention to the data center. However, the company has only committed to a 2026 release for Venice, not for Olympic Ridge, so we could see the Epyc chips first as AMD tries to capitalize on renewed data center demand.

Stop Writing Zod Schemas by Hand: What I Learned After 40 API Endpoints

Sun Shrimp Welfare
The supposition that we live in a "goldilocks zone" is frankly just nonsense built up by an anthropocentric need to feel self-important, like Copernicus I am here to rescue us from a self-absorbed disaster of thought. Indeed, what is required for life to form is the ability to create complex structures with causal persistence times above a threshold. With this in mind we are able to find many areas where organisms could persist, if we just had the eyes to see them, namely the Sun!

I built a Mac app after getting surprised by my Claude bill
<p>A few weeks ago I had one of those dumb founder moments.</p> <p>I was happily using Claude and other LLM tools to build faster, ship faster, and tell myself it was all worth it because I was being "productive".</p> <p>Then I looked at the bill.</p> <p>It was not catastrophic. It was worse than that. It was the kind of number that makes you feel mildly stupid because you know exactly how it happened.</p> <p>A hundred little prompts. Background usage. Testing loops. Switching between tools. "Just one more run." It adds up fast when you are building every day.</p> <p>What annoyed me most was not even the cost. It was the invisibility.</p> <p>I could see CPU usage. Memory usage. Battery usage. Network usage. But the thing I was suddenly paying real money for, tokens, was basically invisible
DeepSource for JavaScript/TypeScript Projects
<p><strong>DeepSource gives JavaScript and TypeScript projects a static analysis platform that goes well beyond what ESLint covers on its own.</strong> Its JavaScript analyzer detects over 100 issues across bug risks, security vulnerabilities, anti-patterns, and performance problems - with Autofix generating ready-to-apply code changes for many of those findings. For teams already running ESLint locally, DeepSource adds a CI/CD layer with a dashboard, PR comments, and automated remediation that turns code review into something closer to an automated workflow.</p> <p>This guide covers everything needed to set up DeepSource for JavaScript and TypeScript projects - from the initial <code>.deepsource.toml</code> configuration to React, Next.js, and Node.js-specific rules, security issue detect
