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 35 years ago, and the first x86, the 8086 in 1978, but they have quite no common points with the latest Pentium 4 or Athlon 64...

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 my own collection online, with now 9492 different 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.

Collection pages code redesign

Collections pages code has been completely rebuild during thos past three weeks, in order to use less MySQL requests. Indeed, my new hoster has requests by hour quota, quite small by the way, and once this one is reach, there are many MySQL errors on the site and it is unusable for all visitors. Maybe some of you already experienced it. And with pages so badly optimised as the collection page, coded more than ten years ago, it could go very fast. Now, requests amount on these pages has been reduced by a 5-50 ratio, depending on collection size. In addition, x86 cpus sub-types are now ordered by architecture in the selection menu. And the stats are also ordered by Architecture, when applicable. And their calculations are now correct, even if you can still see some collection over 100% of one kind of cpu because of doubles, and are now including the different kind of variants in the total.

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

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.
