The Ryzen 9000 Series, a new generation of desktop CPUs from AMD that promises to deliver what the company says is world class gaming and creator performance courtesy of the new Zen 5 architecture, will run cooler than its Ryzen 7000 Series “Zen 4” predecessors but feature the same memory sweet spot (i.e., DDR5-6000), according to a new report that has surfaced ahead of the processors’ expected release later this month. Headlining the new family of chips is the Ryzen 9 9950X, a 16C/32T processor that offers up to a 5.7 GHz boost clock with a 170-watt TDP.
Memory sweet spots for the Ryzen series:
- AMD Ryzen 3000 “Zen 2”: DDR4-3800
- AMD Ryzen 5000 “Zen 3”: DDR4-4000
- AMD Ryzen 7000 “Zen 4”: DDR5-6000
- AMD Ryzen 9000 “Zen 5”: DDR5-6000 (Upper Limit – 6400 MT/s)
From a report:
- “…the CPUs will be able to support DDR5-5600 by default and up to DDR5-6400 memory at a 1:1 fabric clock.”
- “The sweet spot is still going to be DDR5-6000 1:1 but on both X670 and X870, the upper limit will be set at 6400 MT/s.”
- “The advantage that a 1:1 brings to the table is that it will allow for lower latencies and a balanced speed while a higher ratio will allow for better overclocking, & faster data transfer rates but will also lead to poor latencies.”
- “AMD’s Ryzen 9000 ‘Zen 5’ CPUs by default will run cooler than Ryzen 7000 ‘Zen 4’ CPUs. Based on testing with a Ryzen 9 9950X CPU (Default ES), the chip consumed up to 190W of power whereas the Ryzen 9 7950X consumes around 220-ish Watts of power in the same workloads.”
- “The 9950X is almost as fast as the Core i9-14900KS by default and that chip can consume over 300W of power with its extreme profile.”

| AMD Ryzen 9 9900X | 12 / 24 | Up to 5.6 GHz / 4.4 GHz | 76MB | Gen 5 | 120W |
| AMD Ryzen 7 9700X | 8 / 16 | Up to 5.5 GHz / 3.8 GHz | 40MB | Gen 5 | 65W |
| AMD Ryzen 5 9600X | 6 / 12 | Up to 5.4 GHz / 3.9 GHz | 38MB | Gen 5 | 65W |
AMD on its latest chipsets:
The Socket AM5 motherboard family features two new chipsets. Designed to seamlessly integrate with AMD Ryzen 9000 Series desktop processors, the new AMD X870E and X870 chipsets boast support for the latest technologies such as PCIe 5.0, DDR5, USB4, and WIFI7. Socket AM5 platforms are built to last, with support through 2027 and beyond.
