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 21115 different cpus.

New article - VIA C7

Following the article on the VIA Cyrix III / C3, is published today the article on their successors, the VIA C7, which again, unfortunately for VIA, only had a little success on the market.
Released in 2005, however, they had a long life, which continued after the arrival of the VIA Nano, even if the latter then completely eclipsed them.
But this is another story...

Good reading.

New CPUs announced during CES 2021 - Intel

You'll have noticed, seeing the recent news on most of the IT sites, that something is happening this week. Indeed, The Consumer Electronic Show (CES) 2021 in Las Vegas opened on Monday January 11th.
Some announcements were expected and have taken place, such as the one for the Core i5 and i7 Mobile Tiger-Lake H (Tiger Lake-U with frequencies, and TDP, revised upwards), others were less expected, like the one concerning 4 new Tiger Lake-U belonging to the vPro range.
Others were hardly hoped for, like that of the Rocket-Lake-S, but Intel still mentioned these processors, especially the overpowered i9-11900K, whose ever more significant leaks in recent months, suggests that Intel could take the crown of the best gaming processor from AMD. Their release is scheduled for the end of the first trimester. March, in clear.
Intel has even more touched the rest, with Alder-Lake, a line of processors from a Hybrid architecture, like Lakefield, half-Golden Cove, half-Gracemont, scheduled for the end of 2021, if all goes well.
Not at all expected were the announcements of new Pentium Silver and Celeron N-series processors, which Intel is advertising as intended for the education market, based on the Jasper Lake core from the Tremont architecture (which succeeds Goldmont).
Finally, and it is disappointing, Intel announced that they had started shipping their Ice Lake-SP Xeons to their customers, but gave absolutely no information on models.

In summary, are formally announced: Intel Core i5-11300H, Core i7-11370H, Core i7-11375H, Core i5-1145G7, Core i7-1185G7, Core i5-1140G7, Core i7-1180G7, Pentium Silver N6005, Pentium Silver N6000C , Celeron N4500, Celeron N4505, Celeron N5105, Celeron N5100 and the Core i9-11900K.
Some are already added to the database, others will be added shortly.

sales Menu added

Ebay is one of the must today to find CPUs at decent price, not only for collectors. But it is sometimes a little complicated to find youself in this jungle, so, in addition to propose a selection of EBay sales for every CPU pages (whenever sales are available), we now propose you CPUs for sale listings.
Collectors will obviously look on the Vintage section of this new menu, where it will be possible to find some great deals, but modern CPUs section is worth a look too, we can always find a good bargain, especially since listings are sorted by ending soonest. And we all knows that for auctions, great deals are mostly made at the end...
In a second time, we will later propose a advanced search, more powerful than the one of EBay to look for CPUs and other chips, because based on our huge database, in order to find best offers for what you're looking for.

Here it is :

- Vintage CPUs
- Modern CPUs

Disclosure of AMD Ryzen 5000 series

AMD officially announced today their Zen 3 core base Ryzens. But unlike what they did before, it will not be Ryzen 4000x, but Ryzen 5000s.
Maybe AMD estimated that the performance gap would necessitate a number gap as well. Or maybe they finally understood that having CPUs witihin the same number series but with different architecture might be confusing for the consumer (example of the Ryzen 3000G APUs on Zen+ core and the Ryzen 3000 on Zen 2). And as the Ryzen 4000G APUs were already released...
Anyway, 4 models were announced today, the 5600X with 6 cores, the 5800X with 8 cores, the 5900X with 12 cores and last but not least, the 5950X with 16 cores. This later has an impressive boost frequency for the core count of 4.9GHz ! With a 105W of TDP (TDP seems to be defined differently than Intel does).
These CPUs will be available to the market on 05/11/2020 at price ranging from $299 for the 5600X to $549 for the 3900X and "only" $749 for the 3950X ! They will be added in the CPU database meanwhile.

Release of AMD Ryzen 4000G series

AMD officially announced yesterday (sorry for delay) the release og Ryzen 400G lineup. Like Threadrippers Pro announced last week, those cpus will be only available from OEMs... Which is more surprising, because in that case, it's essentially consumer CPUs we're talking about, and its predecesors, the 3000G series, were available in Boxed editions. Do AMD priorize customers to avoid some supply shortage ? Future will tell... Anyway, let's go back with some more technical informations : the lineup consists in 6 consumers CPUs, 3 35W & 3 65W TDB versions, equally divided in Ryzen 3 (4 cores), 5 (6 cores) & 7 (8 cores), and their PRO counterparts, with exactly same specs but with some Pro additionnal features like AMD Memory Guard & AMD Platform Security Processor (PSP). They are using Renoir core, already used before on 4000 mobile Ryzen lineup, wih some performance improvement due to base & turbo frequencies increase (so as the TDPs, reaching an honest 65W). Except that, nothing new from mobile version, they should use same silicium die. They will face Intel Core i3, i5 & i7 essentially, with a big advantage on the graphical part, based on Vega GPU architecture. In the same time, AMD also announced 6 new Athlon Gold & Silver, in normal and Pro versions, based this time again on the mobile Zen+ counterparts released earlier this year. Ryzens have already been added to database, Athlons will follow soon.

Release of AMD Threadripper PRO

AMD officially announced today the release of the Threadrippers PRO lienup. Thos processors will only be available from OEM Partners, like Lenovo, and will only work in WRX80 chipset motherboards. Compared to casual Threarippers, the PRO versions will have twice more PCI-Express 4.0 lines (128 against 64), twice more memory channel (8 instead of 4), will support up to 2TB of RAM (instead of 256GB for the Threadrippers) and will have some security features like AMD Memory Guard which encrypt in real-time the memory. Actually, they are more similar to EPYC CPUs than casual Threadrippers. This 4 CPUs, will fight against Intel Xeon W, even if some benchmarks show comparison with some Xeon Scalable CPUs. They have already been added into the site's database.
