SpecCat.com is a web site I’ve made, mainly for myself trying out LLMs, for easily comparing detailed specifications of different silicon chips; CPUs, APUS, GPUs etc. as shown in screenshots of header below and full at bottom. It should work reasonably well on mobile, but main use case was for larger screens. I tried hard to make it colorful and fun, and dark only. I made this a while ago but never got around to announcing it, so here we are.

I made this because I often check chip specifications, since I find it endlessly fascinating but also for professional use. That is, I often go to ark.intel.com, which unfortunately is not as great a site as it once was. It’s not dense enough. Slow too. And naturally you can’t compare to other chips/products from AMD, AMD Product Specifications, or NVidia GPUs, Compare GeForce Graphics Cards or similar.

I also often have to spec new PCs for work or friends and family based on a budget. Similar to what I discussed in my old blog post from 2020 Core Developer PC™ v20.09.dGPU - AMD 3700X vs Intel i7-10700 8c/16t with NVidia 2060 Super, you know back when DDR RAM was dirt cheap ($110/850 DKK for 2 x 16 GB DDR4 3200)! So having specs at hand makes that a lot easier.

There are, of course, several media sites that have comparisons like TechPowerUp specs databases; CPU Specs Database, GPU Specs Database, SSD Specs Database. Or CPU Monkey.

All of which are fine, but none really go into the detail I am looking for or present such details in a dense enough way and allowing for easy comparison across all details for many products. My main source has, thus, often been Wikipedia ♥, which has great detailed tables, as for example in:

• AMD Zen 5
• Intel Panther Lake
• NVidia Blackwell
• NVidia GeForce RTX 50 Series

Given my unhealthy obsession with performance/minimalism I created this as a vanilla static html, css, javascript web site. Zero libraries or frameworks are used. I spent quite a bit of time prompting and adjusting output to keep site small and instant by bundling everything into just two assets, as shown in Chrome Developer Tool below. Code is a mess for sure, though.

The entire site clocks in at just ~30 KB. A lot less than this blog post. Basic design is very simple, I keep specs in json as js-files for each product family. Then include these in index.html, which means it works fine locally out-of-the-box, as part of deployment all this is then bundled into one single index.html file together with app.js that contains site logic and the favicon. The AI generated logo of a cat holding a silicon wafer then being the only other asset, served as highly compressed avif-file for browsers that support this (almost all). In comparison ark.intel.com is 1.6 MB (that’s +50x more) for just going to welcome page.

Given I have used LLMs for this and no matter what I provide no guarantees to the correctness of the specifications. I checked as much as I could manually, but if you find any mistakes please to let me know. It is very much a preview and I do not know if I will invest more time in it or not. Probably depends on others finding this useful or not, so feedback and suggestions are welcomed.

Ideally, I would like to expand this with other silicon products (e.g. gaming consoles, mobile SOCs), but also include rumored specifications for upcoming chips like Zen 6 or Nova Lake based on leaks from Moore’s Law Is Dead or similar, as when to buy/update a PC for example is a cornerstone of any silicon enthusiasts reasoning.

That’s all!
