AMD has unveiled the first of its Ryzen 7000 series desktop CPUs for high-performance gaming and enthusiast PC users. 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, with support for DDR5 RAM and the PCIe 5.0 interconnect standard. The new CPUs will be available in retail around the world starting from September 27. Pricing for India has not yet been announced but in the US, the flagship 16-core Ryzen 9 7950X is priced at $699 (approximately Rs. 55,360 before taxes). The 12-core Ryzen 9 7900X will cost $549 (approximately Rs. 43,480) while the 8-core Ryzen 7 7700X has a $399 sticker price (approximately Rs. 31,600) and the Ryzen 5 7600X will cost $299 (approximately Rs. 23,680).

The new 'Zen 4' architecture is claimed to deliver an average of 13 percent improved performance in instructions per clock cycle compared to the Zen 3 architecture. This is largely due to increased cache sizes and optimised branch prediction. AVX-512 instruction set support means improved performance for AI inferencing workloads.
