AMD Ryzen 7000 CPUs to go on sale from September 27: Zen 4.5nm, up to 16 cores and 5.7GHz


AMD has announced the first Ryzen 7000 series desktop CPUs for enthusiast PC users and high-performance gaming. The company claims that its top-end 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, which supports DDR5 RAM and the PCIe 5.0 connectivity standard. The new CPUs will retail worldwide starting September 27. Pricing in India has yet to be announced but in the US, the flagship 16-core Ryzen 9 7950X is priced at $699 (about Rs 55,360 previously). tax). The 12-core Ryzen 9 7900X will cost $549 (about Rs 43,480) while the 8-core Ryzen 7 7700X has a sticker price of $399 (about Rs 31,600) and the Ryzen 5 7600X will cost $299 (about Rs 23,680. ).

The new’Zen 4‘architecture is claimed to deliver an average 13% improvement in performance in instructions per clock cycle compared to the Zen 3 architecture. This is largely due to the increased cache size and branch prediction is optimized. AVX-512 instruction set support means improved performance for AI conferencing workloads.

The Ryzen 9 7950X features 16 cores and 32 threads on two “complex cores” chiplets, clocked up to 5.7GHz and 4.5GHz base speed, and 80MB total cache. The Ryzen 9 7900 drops to 12 cores/24 threads and base/boost speeds to 4.7GHz and 5.6GHz, respectively, with 76MB of cache. Both have 170W TDP ratings. The 8-core multi-threaded Ryzen 7 7700X runs at 4.5GHz but ramps up to 5.4GHz, with 40MB of cache. The Ryzen 5 7600X with 6 cores/12 threads runs at 4.7GHz with boost speeds up to 5.3GHz and 38MB total cache. Both of these CPUs have a 105W TDP rating.

Than Ryzen 7000 series models to be launched in the future, alternating between these and also filling the lower end of the stack. Versions with more stacked 3D buffers are also expected later. It is likely that AMD will continue to use previous-generation hardware to serve more budget-conscious buyers, especially those who are upgrading and want to continue using their existing motherboards and RAM. surname.

For the first time, enthusiast-class Ryzen CPUs will have Integrated graphics capabilities. Instead of a set of separate APUs, AMD decided to simply integrate RDNA2GPU-based into four models that have been announced. While a discrete GPU is still needed for serious gaming, this should help with simple diagnostics and workloads.

Power management has also been improved, incorporating a number of efficiency improvements that were previously targeted at mobile CPUs, resulting in a 50% reduction in idle power consumption.

AMD used the TSMC 5nm manufacturing process and claimed a competitive edge over Intel’s 12th generation ‘Alder Lake’ products 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 comes from using some of the lower-powered ‘efficient’ cores. However, Intel’s 13th generation ‘Raptor Lake’ is also expected to be announced soon.

Compared to the previous generation, AMD claims 62% lower power consumption to deliver the same performance or 49% better performance at the same power level. At 65W TDP, the power ratio can go up to 74 percent although this drops to 35 percent at 170W, which is the TDP of the Ryzen 9 7950X.

The new AM5 platform breaks the long-standing socket compatibility of the AM4 platform, which is back as far as First Generation Ryzen CPUs. This is necessary to support DDR5 and PCIe 5.0 RAM and increase socket power delivery. AMD switched to an LGA-style package for the first time, with contact pads on the CPU and pins in the motherboard socket. However, the rack of the cooler has not changed so existing coolers can continue to be used without any adapter. AM5 will continue to be supported until at least 2025, according to AMD.

Lover-class motherboards based on AMD’s X670 Extreme and X670 chipsets will be available at launch. The mid-range B650 Extreme hasn’t been announced before, and the B650 will launch in October. They will vary in feature levels, with only the top-end X670 Extreme supporting PCIe 5.0 for discrete graphics as well as memory.

The company also unveiled AMD Expo, a new platform-level feature to optimize the timing and latency of DDR5 RAM, which is said to boost game performance and make overclocking easier. Finally, AMD CEO Dr. Lisa Su presented a demo of Radeon GPUs Coming Soon based on the RDNA 3 graphics architecture. Performance per Watt is said to be 50% better than the current Radeon RX 6000 generation, and these GPUs will launch later in 2022.
