The AMD Ryzen 7 5800X3D Review: 96 MB of L3 3D V-Cache Designed For Gamers
The level of competition in the desktop CPU market has rarely been as intensive as it has been over the last couple of years. When AMD brought its Ryzen processors to market, it forced Intel to reply, and both have consistently battled in multiple areas, including core count, IPC performance, frequency, and ultimate performance. The constant race to improve products, stay ahead of the competition, and meet customers’ changing needs has also sent the two companies off of the beaten paths at times, developing even wilder technologies in search of that competitive edge.
In the case of AMD, one such development effort has culminated with 3D V-Cache packaging technology, which stacks a layer of L3 cache on top of the existing CCD’s L3 cache. Owing to the fact that while additional cache is beneficial to performance, large quantities of SRAM are, well, large, AMD has been working on how to place more L3 cache on a CPU chiplet without blowing out the die size altogether. The end result of that has been the stacked V-Cache technology, which allows the additional cache to be separately fabbed and then carefully placed on top of a chip to be used as part of a processor.
For the consumer market, AMD’s first V-Cache equipped product is the Ryzen 7 5800X3D. Pitched as the fastest gaming processor on the market today, AMD’s unique chip offers eight cores/sixteen threads of processing power, and a whopping 96 MB of L3 cache onboard. Essentially building on top of the already established Ryzen 7 5800X processor, the aim from AMD is that the additional L3 cache on the 5800X3D will take gaming performance to the next level – all for around $100 more than the 5800X.
With AMD’s new gaming chip in hand, we’ve put the Ryzen 7 5800X3D through CPU suite and gaming tests to see if it is as good as AMD claims it is.
