After the first Ryzen 7 processors with eight cores and the announced Ryzen 5 chips with four and six cores, AMD would also be working on a Ryzen version with twelve and 16 cores. This is to compete with Intel’s hedt platform.
The Ryzen processors released in March are already partly positioned against Intel’s Broadwell E processors, but according to various rumors that DonanimHaber has listed, AMD would be working on a separate platform as a counterpart to Intel’s hedt platform, or the high-end platform. desktop platform. This should be done with a large socket in which CPUs with twelve or sixteen cores fit. Intel’s top model, the Core i7-6950X, has ten cores and twenty threads. The Cinebench score of an engineering sample of the sixteen-core chip would be 2500 points, where the 6950X gets about 2000 points. The socket would be a derivative of the server socket for the Naples processors and would be called SP3r2. The socket would have more than 4000 pins and the processors would be implemented as LGA chips, so the pins are in the socket.
The CPUs, codenamed Threadripper, would be combined with a new X399 chipset. Two variants of the high-end CPUs have already been identified and would have twelve and sixteen cores. AMD realizes this by packing two Summit Ridge dies into a single package. The two ‘Ryzen 7’ dies are interconnected and thus work as multi-chip modules. That would mean that the sixteen-core variant has four core complexes, and the twelve-core version has one core disabled in each core complex. So the configuration is 4-4-4-4 or 3-3-3-3 cores in each ccx. Like the other Zen cores, the processors support smt, which would bring the number of threads to twenty-four or even thirty-two.
Because two Summit Ridge dies are used, the chips would have four DDR4 memory channels and as many as 48 PCIe lanes. The CPU with twelve cores would have a TDP of 140W, but the clock speeds are still unknown. The sixteen-core variant would have a TDP of 180W and clock speeds of 3.1GHz to 3.6GHz. In addition, the Threadripper CPUs would have a B2 revision of the Zen cores; the Ryzen chips are B1 chips. AMD is rumored to announce the new platform at Computex in Taipei in early June. Prices are of course not yet known.
