AMD Ryzen 7000 series CPUs to Go on Sale From September 27: Zen 4 architecture , 5nm, Up to 16 Cores and 5.7GHz

AMD has introduced the first desktop CPUs in its Ryzen 7000 series for high-performance gaming and avid PC users. The company claims that its top-of-the-line Ryzen 9 7950X will be the world’s fastest processor for gaming and content creation. These CPUs are based on the new “Zen 4” architecture and introduce a new platform called AM5 that supports DDR5 RAM and the PCIe 5.0 connection standard. The new CPUs will be available in stores worldwide from September 27th. Pricing for India hasn’t been announced yet, but in the US, the flagship 16-core Ryzen 9 7950X is priced at $699 (roughly Rs 55,360 before tax). The 12-core Ryzen 9 7900X is $549 (roughly Rs. 43,480), while the 8-core Ryzen 7 7700X has a sticker price of $399 (roughly Rs. 31,600) and the Ryzen 5 7600X is $299 dollars (approx. Rs. 23,680).

The new “Zen 4” architecture is said to deliver an average of 13 percent improved performance in instructions per clock cycle compared to the Zen 3 architecture. This is mainly due to increased cache sizes and optimized branch prediction. AVX-512 instruction set support means improved performance for AI inference workloads.

The Ryzen 9 7950X has 16 cores and 32 threads on two “core complex” chipslets, a boost speed of 5.7 GHz and a base speed of 4.5 GHz, and a total of 80 MB of cache memory. The Ryzen 9 7900 comes down to 12 cores/24 threads and base/boost speeds of 4.7 GHz and 5.6 GHz respectively with 76 MB of cache memory. Both have 170 W TDP figures. The Ryzen 7 7700X with 8 multi-threaded cores runs at 4.5 GHz but boosts to 5.4 GHz with 40 MB cache. The 6-core/12-thread Ryzen 5 7600X runs at 4.7GHz with a boost up to 5.3GHz and 38MB total cache memory. These two CPUs both have 105W TDP values.

More Ryzen 7000-series models are slated to launch in the future, slotting in between and also filling the bottom of the stack. Versions with additional stacked 3D cache should also come later. It’s likely AMD will continue to use previous-gen hardware to cater to more budget-conscious buyers, particularly those looking to upgrade and continue using their existing motherboards and RAM.

For the first time, all enthusiast-class Ryzen CPUs will have integrated graphics capabilities. Instead of a separate set of APUs, AMD has opted to pack simple RDNA2-based GPUs into the four announced models. While a discrete GPU is still required for serious gaming, this should help with light workloads and diagnostics.

Power management has also been improved by incorporating several efficiency improvements previously targeted at mobile CPUs, resulting in a 50 percent reduction in idle power consumption.

AMD has used a 5nm TSMC manufacturing process and claims a competitive advantage over Intel’s 12th Gen “Alder Lake” offerings in terms of die area and performance per watt. Single-threaded performance should be better as AMD points out that Intel’s high core count is due to the use of multiple underperforming “efficiency” cores. But Intel’s 13th generation “Raptor Lake” should also be announced soon.

Compared to the previous generation, AMD claims 62 percent less power consumption at the same performance or 49 percent better performance at the same performance level. At a TDP of 65W, the power scaling can go up to 74 percent, although at 170W, the TDP for the Ryzen 9 7950X, the figure drops to 35 percent.

The new AM5 platform breaks the socket compatibility of the long-running AM4 platform, which dates back to the first-gen Ryzen CPU series. This was necessary to support DDR5 RAM and PCIe 5.0 and to increase the power delivery of the socket. AMD is moving to an LGA-style package for the first time, with contact pads on the CPU and pins inside the motherboard socket. However, the cooler bracket has not been changed, so that existing coolers can continue to be used without an adapter. According to AMD, AM5 will be supported until at least 2025.

Enthusiast-class motherboards based on AMD’s X670 Extreme and X670 chipsets will be available at launch. The previously unannounced mid-range B650 Extreme and the B650 will follow in October. These vary in terms of feature level, with only the top-of-the-line X670 Extreme supporting PCIe 5.0 for discrete graphics as well as storage.

The company also introduced AMD Expo, a new platform-level feature for optimizing DDR5 RAM timings and latencies that the Sp
