Sep 23, 2022   New AMD Ryzen PRO processors released
AMD launched new Ryzen Pro CPUs for business-class desktop systems. Unlike previously announced consumer-oriented Ryzen 7000 series desktop products, built on latest Zen 4 microarchitecture and manufactured on 5nm process, Ryzen Pro parts utilize older "Zen 2" and "Zen 3" architectures. "Zen 3"-based processors are Ryzen 5 PRO 5645, Ryzen 7 PRO 5845 and Ryzen 9 PRO 5945. Back in August, they were spotted in specifications of Lenovo ThinkStation P358 computer. Their characteristics are now available on the AMD website. AMD also released Ryzen 3 PRO 4355G and 4355GE "Zen 2" CPUs.   [Full story]

Site updates

Nov 27, 2024: More missing CPU specs posted

I finished updating CPU specifications pages, which means that the site has all processor families launched by AMD and Intel. This last update includes recently released AMD families of mobile and embedded processors.   [More]

Nov 25, 2024: Specifications pages: new fields

I added several new fields, that provide CPU architecture features or CPU support information, to CPU specifications pages:

  • The "Chipsets" field contains the chipset name or chipset names, compatible with the current processor. If details icon is displayed then you can click on it to see a list of extra peripherals, offered by one of the chipsets. Please see how it looks on the Intel Core Ultra 285K page. The "Chipsets" is the last field in the "Integrated peripherals / components" section.

Oct 30, 2024: Missing AMD desktop and server specs posted

I continued working on specifications of recently released microprocessors. This time I posted specs of desktop and server AMD families and updated processors' launch time pages.   [More]

Oct 07, 2024: Missing Intel specs posted

Specifications of pretty much all missing Intel microprocessors were posted on the website. These include desktop 14th Generation Core CPUs, mobile Core series 2 (Lunar Lake) microprocessors, mobile and embedded Core series 1 models, 5th generation Xeons, Xeon 6700 and 6900 series, Xeon E-2400, Xeon W-2500/W-3550 and embedded Xeon D-1800/D-2800 series.   [More]

Mar 24, 2024: Website enhancements for mobile devices

The CPU-World website was originally designed to be viewed on large desktop PC screens. Even though I redesigned the site in 2016, it was still tailored to desktop users. Considering that more than of half of all web traffic now comes from mobile devices, I decided to make the website mobile friendly and implement so-called "responsive web design", which adapts web pages to user's screen size by changing page layout on the fly. This approach seemed to be the most appropriate as it allowed me to keep the original CPU-World design for desktop users, while mobile users could be served pages optimized for their smaller screens.   [More]

Sep 05, 2022   AMD announced socket AM5 platform and Ryzen 7000 series CPUs
AMD announced new socket AM5 platform, that will be utilized for future desktop microprocessors. The new socket is a Land Grid Array, or LGA, type of socket with 1718 contacts, and it will be supported by upcoming X670, X670E, B650E and B650 chipsets. AMD also announced first four members of Ryzen family, compatible with the socket AM5. Two more affordable models are six-core Ryzen 5 7600X and eight-core Ryzen 7 7700X, both having 32 MB of L3 cache and 105 Watt TDP. Two top of the line processors, 12-core Ryzen 9 7900X and 16-core 7950X, feature 64 MB L3 cache, but have much higher 170 Watt TDP. New CPUs will be priced from $299 to $699 and they will be available on September 27.   [Full story]

Dec 20, 2017   "Gemini Lake" Pentium and Celeron CPUs launched
Earlier this month, Intel introduced first budget dual- and quad-core systems on a chip, built on "Gemini Lake" design. As you may know, previous generation of processors for inexpensive desktop and notebook computers was based on "Apollo Lake" design, which was produced on 14nm technology, and combined 2 or 4 "Goldmont" CPU cores, Intel HD 500 or HD 505 graphics, DDR3 / DDR4 memory controller, and a host of I/O interfaces. "Gemini Lake" SoCs are also based on 14nm process and incorporate 2 or 4 cores, but come with a number of improvements.   [Full story]
