Cpus are really fascinating for computers fans : it is central piece of every PC, and so, the most important.
However, this enthusiasm for cpus faslty disapear once they're a little old : last released cpus are admirated, but oldest are subjects of jeerings. Because, the symbol of power that cpus represents, grows old very bad.
And that's why, there are only a few people who collects cpus, unlike stamps, coins or even beer bottle caps...
Nevertheless, it is far from being without interest, because of large number of different models, because of their difference and because of their very fast evolution : the oldest cpus, Intel 4004 was released 50 years ago, and the first x86, the 8086 in 1978, but they have quite no common points with the latest Core i9 or Ryzen...

This site is trying, on the first hand, to enumerate all different existing models of x86 cpus (see Search menu), to make you discover their history, their characteriscs and their visual or electronical specificities (see History menu), and on the other hand to put online different collector's collection, with now 21502 different cpus.

Release of first Lakefield Core i3 & i5

This news has not been spread out widely, more on very specialized and technical HW site than on general IT ones, but Intel announced on 06/10 the release of two new Mobile Core i3 & i5, with Lakefield codename. However, these two chips have something particular from any of their predecessors, something more or less already seen on ARM side, but never from Intel nor on any other x86 chip : heterogeneous cores ! Indeed, they have a "big-core", Sunny cove type, the architecture which is trying to finally replace Skylake, and 4 small-cores, Tremont type, which is an architecture developped in parallel and which succeed to Goldmont, represented by latest Atoms, Celerons N & J Series & Pentium Silver, for low power application like tablets, 2 in 1, entry level laptops or smart TV. Lakefield, due to Sunny Cove core will be more powerful though, and branded as core i3 and i5, will be used in very thin pricy laptops. These processors will be added in database soon, but knowing that the database was ordered by company/models/architecture, here, with models having cores from different architecture, it won't be fun to fit into boxes...

Release of 3rd generation of Intel Xeons Scalable

Intel officially announced the release of the third generation of Xeon Scalable, now exclusively dedicated for servers (4 to 8 sockets systems). These modeles are based on a new Copper Lake core, the very last, we hope, from the Skylake Architecture for professionnal oriented cpus. 11 Gold & Platinium Models are launched, and will be added soon in our database, with a core count which varies from 16 to 28, with base frequencies increased, between 2.3 & 3.1GHz, and According TDP in great increase, between 150 & 250W, not less. Most of the models have boost frequencies above 4Ghz, except 2. No Xeon Silver nor Bronze is announced. Those modeles offers very few new features compared to second generation Xeons Scalable : latest Optane 200 series compatibility and Deep Learning Boost improvement, which can now use natively 16-bits floats, bfloat16. Which is very useful for Artificial Intelligence, which uses massively 32-bits floats, FP32 (by using 2 bfloat16 to handle FP32s, calculations are made faster than using 4 8-bits floats) Intel's communication is mainly based on that 2 points, Optane & AI. Which may be enough for the main customers of this kind of cpus, for which needs in AI calculations are always greater and greater.

Buying Cheap Chinese Motherboards - Part III

The third chapter of the Chinese Motherboards buying guide is now online. This time, we will focus on a quite unknown plateform. Everyone knows the LGA1366 plateform, and what they think being its successor, the LGA2011. But actually, the real successor of the LGA1366, was the LGA1356. This plateform only hosted Xeons, Sandy Bridge and Ivy Bridge architecture, very similar to LGA2011 ones except that they were globally less powerful. Anyway, still more than enough power for today's usages.

MCS-86 familly has been added in Peripherals & Support chips database. 48 models are listed for now, corresponding to those initially released along with the 8086 CPUs. Some other chips, sometimes associated with this family, but released later or developped to work with later CPUs like 80286 or 386, and which has 5 digits partnumbers (against 4 for the first ones), will be added later.

MCS-85 familly has been added in Peripherals & Support chips database. 116 models have been listed, which allow us to have now more than 9000 chips listed in the site database. This familly contains all the chips planned to work with 8085s, but not only, some of them can alos work with oldest 8080 or newest 8086, some even with 8048s MCUs.

Buying Cheap Chinese Motherboards - Part II

The second chapter of the Chinese Motherboards buying guide is now online. This time, we will focus on the LGA2011 Plateform, for Sandy Bridge and Ivy Bridge CPUs. It is older than the LGA2011-3, but still more than enough powerful and much cheaper. So clearly worth it as you'll see.

New article - Buying Cheap Chinese Motherboards - Part I

A new article is put online today. It is about Cheap chinese motherboards that you can find on Aliepxress or on Ebay currently. As a cpu collector, I like to test my cpus and benchmark them. But to do so, I needed to build a complete, or almost, machine. Doing it one time is cool, but there are so many sockets and platforms that at the end, it would become really expensive. So I had to find some solutions to get this activity cheaper. I first began to find one cheap LGA1356, because you cannot find a used one for a good price currently. So as many server motherboards. And after having it, using it and benchmarking it, it appeared to me that it was a very valid solution. Not only for testing, but for everyday use. So, I wanted to share my experiences and my knowledge of this market, what are the best and most interesting models for every plateforms...etc. For the first chapter, we will start with the most powerful ones, the LGA2011-3 motherboards.

Home page updated

Home page, and more precisely the News section, has been completely redesigned in order to be more readable and more modern. News are now all display in date order, whatever their category, with some pciturs to illustrate. It is also now possible to browse directly all the oldest news, with a little menu, while before, only 9 news for each categroy were displayed. Therefore, "Archives" sections of the "Miscellanous" menu, is now useless and has been deleted

New banner on the right

A new banner has been added on the right, with a photo a link to a "Processor of the day", chosen randomly, a top 5 of the most visited cpus on the site, a top 5 of the most sold cpus on EBay, and the list of the most powerfuls cpus from Intel & AMD, for each categories in Desktop, Mobile & Server. And for those who orders on the site, a shopping basket reminder will pop-up on the top of the right banner, with a button to pay directly on Paypal
