I would guess that Intel's 14th generation will ditch DDR4 for good, but as of now, DDR4 compatibility is one thing that the i9-13900K has going for it over the Ryzen 9 7900X3D.

The Ryzen 9 7900X3D, utilizing AMD’s 3D V-cache technology, is the second-best CPU from Team Red to hit the market. It provides users with a more affordable high-end option for their gaming rigs. In this post, we will delve into the specifications and performance of this new processor. Games performance can improve as cache size increases, as it will reduce delays when retrieving commonly used game assets from memory.This technology involves a 64MB SRAM die that supplements the 32MB on-die L3 cache of one of the two CCDs present in these processors. The combined 96MB cache has a significant impact on computing latencies, particularly when it comes to gaming. With this enhanced cache, users can expect improved gaming experiences, faster processing times, and overall better system performance. Ryzen 7900X3D: Performance

I tested the AMD Ryzen 9 7900X3D inside of a newly built machine utilizing Kingston Fury Beast DDR5 RAM, an Nvidia RTX 4090, and a brand new RM1000X PSU. The chip was utilized heavily for gaming in the benchmarked titles as well as in games such as Mortal Kombat 11, Cyberpunk 2077, and Tekken 7. AMD's 3D V-Cache technology adds a cache layer to the processor, adding more CPU cache memory. This allows it to process instructions faster since they're already stored on the faster processor cache instead of slower RAM. Our expectations for the 7800X3D are high - after all, the CPU's design permits its full 120W TDP to be dedicated solely to an eight-core chiplet complete with performance-boosting 3D V-Cache. By comparison, the 7950X3D and 7900X3D released in February split that power budget across two chiplets, only one equipped with the extra L3 cache, so we could potentially see even greater performance than these CPUs. It's a similar story to the Intel Core i9 13900K, a fantastic gaming and content creation CPU - but one that relies on scheduling algorithms built into Windows to make full use of its asymmetric performance core and efficiency core design.

Overall, both CPUs are highly capable and powerful, and the performance difference between them is not significant. However, in high-end PC gaming, even the slightest advantage can make a difference, and the Ryzen 9 7900X3D’s larger cache size and energy efficiency make it a strong contender for gamers seeking optimal performance. Ryzen 9 7900X vs 7900X3D: Price Another difference between these two CPUs is the amount of L3 cache they offer. The Ryzen 9 comes with a whopping 128MB L3 cache, which is significantly more than the Ryzen 7’s 96MB. This extra cache can boost performance in certain applications requiring more memory. X" means it is an extended frequency range CPU. These CPUs support higher frequencies than standard CPUs. We test Intel processors with the power limits fully removed for our standard measurements, so those chips run beyond the 'recommended' power settings but remain within warranty. We used DDR5 for both the Raptor Lake and Zen 4 processors. While we eagerly anticipate the release of the Ryzen 9 7900X3D, we can’t say for certain which CPU is the superior one just yet. However, based on the specs, it seems likely that the 7900X3D will outperform the 7900X due to its larger cache size. This cache acts as a storage space for frequently accessed data, which can greatly improve gaming performance. Despite the higher price tag, the improved performance may justify the investment for those who require the best possible performance in their gaming experience.

There's very little that we can fault the Raptor Lake flagship on with its performance. That's due to the excellent Raptor Cove and Gracemont cores with its hybrid architecture that makes it a processor that's difficult to beat outside of its expensive price point. As far as a short summary goes, we’ll say one thing — both chips are excellent and their performance is worthy of a current-gen flagship. Right now, both are easily among the best processors on the market, and only high-end chips like the Intel Core i9-13900K can hope to beat either of the two Ryzens. Compared to the more expensive chipsets, the AMD Ryzen 9 7900X3D absolutely holds its own with the 7950X3D and the 13900K, with the largest gap visible seen with how AMD's flagship handles Returnal. This is likely due to the fact that the 7950X3D utilizes an additional four cores and eight threads, and Total War series has always been Intel's strongest gaming benchmark, which remains the case here.The announcement from AMD of their Ryzen 7000 X3D lineup was one of the most exciting of CES 2023. These 3 CPUs all make use of the new Ryzen X3D technology which allows for significantly higher cache sizes. The 7900X3D is the middle child of the range and we are already almost able to get our hands on this sleek new CPU that is released sometime today. But how can it? Unless the OS is intensely profiling them somehow, or just looking up executable names, I dont see how it can tell the difference between ffmpeg and a minecraft server maxing out a core. AMD may have confirmed the release date of the hotly-anticipated Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D, but it doesn't look intentional. According to OC3D, AMD briefly published a launch date of February 14 for its new processors.
