AMD’s Ryzen 7 5800X3D featuring 64MB of 3D stacked L3 V-Cache is all set to launch in the next 20-30 days, with the first round of shipments already underway. The octa-core processor will be the first consumer chip to feature AMD’s V-Cache technology, following the Milan-X server lineup. The Zen 3 core architecture and TSMC’s 7nm (N7) node will be retained, but as we’ve seen with the 3rd Gen Ryzen lineup, throw enough cache at a game, and it’ll (probably) run well enough.
According to Greymon55, the Ryzen 7 5800X3D might be priced as low as $350. That’s more than the $299 Ryzen 7 5800X but less than the $400 Intel Core i7-12700K, placing it at a crucial point in the consumer market. Over the past several months, the latter has been the most popular Intel SKU with the Ryzen 5 5600X and Ryzen 7 5800X being AMD’s leading contestants.
Sampling and reviews should also begin in the coming weeks. In addition to the 32MB of L3 cache paired with the Core Complex on the CCD, the Ryzen 7 5800X3D will consist of an additional 64MB cache die stacked atop the compute chiplet. This brings up the overall L3 cache size to 96MB. As already demonstrated with the 3rd and 4th Gen Ryzen processors, the last-level cache has a substantial impact on gaming performance. AMD’s own testing shows a boost of roughly 15% with the 64MB cache die.
One drawback of 3D stacking is that it adversely affects the thermals of the CCD, prompting a drop in the boost clocks. The Ryzen 7 5800X3D pulls down the 4.7GHz peak frequency of its predecessor to 4.5GHz. Regardless, it still manages to exhibit a generational uplift in gaming performance which may make the Ryzen 7000 “Zen 4” processors seem less impressive.
Board partners have already started prepping their motherboards for Zen 3D. Gigabyte has rolled out support for the Ryzen 7 5800X3D in its latest firmware update. Based on the AGESA ComboV2 PI 126.96.36.199B BIOS, the release adds “Upcoming New CPU support” as per the patch notes. Considering that the Ryzen 7 5800X3D is the only AMD SKU set to launch in the next 2 to 3 months, it’d be safe to assume that we’re looking at a possible launch in March or April.
