Amd Introduced Desktop Ryzen 4000: 7-Nm Processors For Office And Home
AMD has announced a line of Ryzen 4000 processors designed for desktop PCs and monoblocks. The chips are manufactured using a 7-nm process, use a non-new Zen 2 architecture, and are essentially "pumped-up" versions of the Ryzen 4000 laptop released earlier this year.
The main task of the new processors is to compete with Intel chips for middle-class PCs, currently dominating the market for office and non-gaming home computers. All 18 models in the new line are equipped with built-in Radeon graphics, and half of the regular heat output does not exceed 35 watts. The first feature is important for undemanding home users, who can play many games with low graphics settings without spending money on an expensive video card. The second is for corporate customers who want to optimize office energy consumption.
Desktop Ryzen 4000s continue to use the AM4 socket, which will make it easier to upgrade many existing computers. However, this is a matter of the future — while the new chips are available only to computer manufacturers and are not sold at retail. Systems based on them from leading PC manufacturers should be available in the fall of this year.
The most productive model, the Ryzen 7 4700 G, runs at 3.6 GHz with the ability to accelerate to 4.4 GHz and is equipped with 12 MB of second-and third-level cache. Ryzen 5 4600G has six cores/12 threads, a frequency of 3.7-4.2 GHz and 11 MB of cache, and Ryzen 3 4300G has four cores, frequencies of 3.8-4 GHz and 6 MB of cache.
None of the new desktop chips, including the flagship Ryzen 7 Pro 4750G with eight cores/16 threads and a 65-watt TDP, exceeds the performance of the top processors of the previous desktop line, the Ryzen 3000. AMD generally prefers comparisons with Intel (they claim that the new products are faster than similar "corporate" Intel vPro), rather than with its processors of the previous line of the same level. For example, the claim of a 2.5-fold increase in performance compared to the previous generation is based on a comparison of the Ryzen 7 4700G with The Ryzen 7 3700X, which is not equal in positioning, but with the Ryzen 5 3450G located lower in the line. Also, the 4000-series chips use the PCI Express bus of the third, rather than the more advanced fourth version.
