AMD announced their first three desktop CPUs in the Ryzen series, the Ryzen 7 1800X, Ryzen 7 1700X and Ryzen 7 1700.  These are the first commercial products from AMD based on the Zen architecture, in which the company has been working for four years to become competitive with Intel in the high-end PC space again.

AMD Ryzen CPUs for High-End Desktops

Company president and CEO Lisa Su announced that AMD has exceeded its stated goal of pushing 40 percent more instructions per clock with Zen compared to the previous Excavator architecture, and in fact has managed to achieve a 52 percent increase.

All the three Ryzen 7 models are manufactured in 14nm process, have eight cores and support 16 threads. At the top of the lineup is the Ryzen 7 1800X, which has a base clock speed of 3.6GHz and a boost clock of 4GHz. AMD says this is the fastest 8-core processor available in the market right now. The Ryzen 7 1700X has base and boost speeds of 3.4GHz and 3.8GHz respectively, while the Ryzen 7 1700 runs at 3GHz and 3.7GHz respectively. The 1800X and 1700X have 95W TDP ratings while the 1700 is a 65W.

Su demonstrated a Ryzen 7 1800X PC beating Intel’s 8-core, 16-thread Broadwell-E Core i7-6900K in the Cinebench R15 benchmark as well as in a video encoding operation in Handbrake using identical configurations. Gaming performance also offers superior performance due to the eight physical cores. Normal workloads usually will not get much benefits from having more cores.

AMD is planning to take on Intel’s Core i7 CPUs. AMD will sell the Ryzen 7 1800X at a recommended retail price of Rs. 37,999 ($499 in the US) as opposed to the $1,050 sticker price of the Core i7-6900K. The Ryzen 7 1700X is priced at Rs. 29,499 in India ($399 in US) and the Ryzen 7 1700 will cost Rs. 24,499 ($319 in the US) – each roughly $25 less expensive than Intel’s Core i7-6800K and Core i7-770K, which they are positioned against.

The three CPUs are available for preorder, and will officially go on sale from March 2. New motherboards with the AM4 socket will be available from Asus, Gigabyte, MSI, Biostar and ASRock on launch day.
