ZEN 5 architecture and Ryzen 9000:
ZEN 5 architecture:
Dr. Lisa Su unveiled four new processors in June, scheduled for launch on July 31st. In the end, the launch was pushed back to August 7th for the Ryzen 5 9600X and Ryzen 7 9700X. The launch of the AMD Ryzen 9 9900X and Ryzen 9 9950X is scheduled for August 14th. These new Ryzen 9000s benefit from 4nm etching by TMSC and are based on the new Zen 5 architecture. To be precise, it is the CCDs(core compute die) that are etched in 4nm.
The improved etch finesse means that Ryzen 9000s are more energy-efficient than the previous generation. This is one of the advantages of this new generation highlighted by AMD.
ZEN 5: 4 processors for the moment
The launch of the range is therefore complete today. As far as launch prices are concerned, AMD has announced a price of $276 (€308.90) for the 9600X, $359 (€396.90) for the 9700X, €548.90 for the 9900X and €714.90 for the 9950X.
The Ryzen 5 9600X is the equivalent of the current Ryzen 5 7600X. It has the same number of cores: 6c/12t. However, it uses new-generation ZEN 5 cores. In terms of frequency, this processor will operate with a single-core boost frequency of 5.4 GHz, i.e. 100 MHz more than the 7600X. The other big difference is the TDP, which drops from 105 to 65 watts for the 9600X! We should see an interesting gain in terms of temperature and, above all, power consumption.
On the Ryzen 7 9700X side, we find a 8c/16t like the Ryzen 7700X as well as a frequency gain of 100 MHz compared to the previous generation. Here too, the TDP drops from 105 to 65 watts. It’s not hard to imagine that this type of TDP would have been chosen for the ‘future’ Ryzen 5 9600 and Ryzen 7 9700.
The Ryzen 9 9900X, with its 12c/24t, will come up against the Ryzen 9 7900X. Compared with the previous generation, the maximum frequency remains identical at 5.6 GHz in single-threaded mode. As far as TDP is concerned, it has improved from 170 watts for the Ryzen 9 7900X to 120 watts for the Ryzen 9 9900X. On the next page, we’ll look at the impact of lower TDP on frequencies.
The packaging of these new processors is virtually identical to that of the previous generation. The colours are slightly darker and there is no cooling system available. AMD and Intel have not been offering cooling units in bundles for some time now .
The new chipsets are coming soon:
The test of these two processors will be carried out on a ROG Crosshair X670E GENE motherboard, which of course remains perfectly compatible with its AM5 socket. AMD has already unveiled its new AMD 800 chipset, and a number of manufacturers have also unveiled their first motherboards. These include the AMD X870E, X870, B850 and B840 chipsets.
We should be able to unveil the first motherboards in the coming weeks.
