MojoKid writes: AMD launched its 2nd Generation Ryzen processors today, based on a refined update to the company’s Zen architecture, dubbed Zen+. The chips offer higher clocks, lower latencies, and a more intelligent Precision Boost 2 algorithm that improves performance, system responsiveness, and power efficiency characteristics. These new CPUs still leverage the existing AM4 infrastructure and are compatible with the same socket, chipsets, and motherboards as AMD’s first-generation products, with a BIOS/UEFI update.
There are four processors arriving today, AMD’s Ryzen 7 2700X, the Ryzen 7 2700, the Ryzen 5 2600X, and the Ryzen 5 2600. Ryzen 7 chips are still 8-core CPUs with 20MB of cache but now top out at 4.3GHz, while Ryzen 5 chips offer 6 cores with 19MB of cache and peak at 4.2GHz. AMD claims 2nd Gen Ryzen processors offer reductions in L1, L2, and L3 cache latencies of approximately 13%, 34%, and 16%, respectively. Memory latency is reportedly reduced by about 11% and all of those improvements result in an approximate 3% increase in IPC (instructions per clock). The processors now also have official support for faster DDR4-2933 memory as well. In the benchmarks, 2nd Gen Ryzen CPUs outpaced AMD’s first gen chips across the board with better single and multithreaded performance, closing the gap even further versus Intel, often with better or similar performance at lower price points. AMD 2nd Gen Ryzen processors, and new X470 chipset motherboards that support them, are available starting today and the CPUs range from $199 to $299.
