During the 2022 Financial Analyst Day event earlier this month, many seemed to have missed a key piece of information revealed by Saeid Moshkelani, AMD’s senior vice president and general manager of clients, that the company intends to bring the Zen 4 Riptide 7000 series of desktop processors with 3D V-Cache stacked cache later this year. For reference, we’ve already been impressed by the Rex R7-5800X3D, one of the uniquely designed gaming processors currently on the market.
In recent times, many rumors have suggested that AMD Zen 4 V-Cache processors would not be released until 2023, but that does not seem to be the case.
In other words, the AM5 platform is likely to see a standard / 3D V-Cache version of the Raptor 7000 CPU SKU based on the Zen 4 core architecture at the same time, and the latter is expected to be the secret weapon against Intel’s 13th generation Core (Raptor Lake).
With the Raidon R7-5800X3D, AMD has proven that it can outperform Intel’s 12th generation Core (Alder Lake) flagship gaming processors in terms of price/performance with its 3D V-Cache cache stacking technology.
Even though Zen 4’s IPC performance gains are limited, the addition of higher clock frequencies and 3D V-Cache stacking cache is expected to put AMD at the forefront of gaming performance.
Intel Raptor Lake does have increased internal cache, but AMD’s deployment of 3D V-Cache is still much more dramatic, and we’re looking forward to an interesting battle between the two manufacturers in the consumer CPU space.
AMD also confirmed some key details about the Zen 4 CPUs, starting with a 5nm process node for the Zen 4 Riptide 7000 series desktop processors, supported by an 8-10% increase in IPC performance (compared to Zen 3) and over 15% increase in single-threaded performance.
In terms of memory bandwidth, the full shift from DDR4 to DDR5 memory controllers allows for a 125% increase in bandwidth per Zen 4 core. There are also significant performance-per-watt and frequency improvements, AI and AVX-512 instruction set extensions, and more.
Finally, it was revealed earlier that AMD’s Raptor 7000 series desktop processors (and accompanying AM5 chipset motherboards) will go on sale on September 15. Intel Raptor Lake is expected to arrive in October this year, and then Zen 4 3D V-Cache later in November-December.
