AMD Ryzen 9 7900X3D Desk-top Processor (12-core/24-thread, 140MB cache, up to 5.6 GHz max boost)

Product Information

You can read the deep-dive details on AMD's thread-targeting implementation here, but the key takeaway is that the four different components work together to automatically alter the thread assignments into the cores. This technique assures the OS thread scheduler can target the correct cores based on current usage — the 3D V-Cache enabled chiplet for cache latency-sensitive tasks like gaming, or the standard chiplet for workloads that respond best to higher frequencies. You can also override the automatic switching between core-ranking modes to customize the settings, but we found that the automatic mechanisms work well. 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

Remember that we were looking for coolers to use with the high-temperature-producing Ryzen 9 7900X3D CPU, so we prioritized those that could maintain a low temperature under a heavy load. Aesthetics and Build Quality Its functionality, ease of use, and sound quality are all exceptional. Furthermore, the product’s other benefits are significant and difficult to ignore. The AMD Ryzen 9 7900X3D would benefit from Arctic’s Liquid Freezer II 360, a high-end cooler with excellent acoustics and a cooling capacity of more than 290W. Overall, it is the Best Overall CPU Cooler For Ryzen 9 7900X3D. Alphacool Eisbaer Pro Aurora 240KyaraM said:A regular 7950X or a 13900K are more than enough for a mixed gaming + productivity system, lmao. I would even argue that a step below that is plenty for most people, too. With this stupid thing, you trade a quite significant amount of productivity for some more gaming performance you don't need as much as you need food on the table. Read Igor's German review yesterday, in some cases where the 7950X is leading the 13900K in productivity, the 7950X3D places behind the 13900K. It sometimes even placed behind the freaking 7700X!!! How much is slightly better gaming performance worth to you? Yeah, 7950X3D trails behind a bit with AutoCAD. It also consumes less power though, and in that regard it is quite remarkable that it takes a solid 3rd spot e.g. with Cinebench R23, only "slightly" behind the top 2 in performance and way before the 4th. We put a lot of time and effort into compiling this list of the finest CPU coolers for this cutting-edge processor. The most important criteria we used to choose which coolers to include here are as follows. Opening with the flagship SKU, the Ryzen 9 7950X3D shares many of the same characteristics as the Ryzen 9 7900X, including 16-cores and 32-threads and a turbo frequency of up to 5.7 GHz. The enhanced chip offers 128MB of L3 cache, which is comprised of 64 MB of existing pooled L3 cache in the CCDs, and another 64 MB sliced on top with TSVs (presumably placing 64MB on one CCD, creating an unbalanced cache). Curiously, the official TDP is also much lower, with the chip rated at 120 W versus 170 W for the regular 7950X. Consequently, the 7950X3D has a lower base core frequency of 4.2 GHz, versus 4.5 GHz. Although the Ryzen 9 7950X3D has a 300 MHz slower base frequency, having the same turbo frequency of 5.7 GHz means that peak performance can be similar, though in heavily multithreaded situations the lower TDP is undoubtedly going to come into play. AMD Ryzen 7000X/X3D Series Line-Up As you can see, when we put these two powerhouses head to head we see identical core and thread counts but not much else stays the same. Perhaps the standout difference is the Ryzen 9 7900X3D’s gigantic cache size, which comes into being thanks to its X3D technology.

If you are looking for a high-performance cooler with as few connections as possible, don’t miss out on Arctic Liquid Freeze II 360. The ARCTIC is both performance-effective and space efficient, requiring only two motherboard slots to pair the cooler with your PC: one for the 4-pin PWM connection slot and another for the 3-pin A-RGB lighting slot. Only fusing the SRAM onto one CCD also reduces manufacturing costs, as the hybrid bonding process and additional chiplet make this an expensive technology. AMD also says that using two V-Cache chiplets doesn’t provide enough performance uplift to justify the extra costs. In recent benchmarks, we have observed that the 7900X3D produces results that are closer to those of the Intel i9-13900K, thereby reducing the gap that existed between the two processors in this range. With such comparable performance, AMD users can look forward to a brighter future in this 7000 series generation. Furthermore, AMD has regained its title as the best gaming CPU in the market, edging out Intel once again. Ryzen 7900X3D: Conclusion It’s important to note that both the Ryzen 9 7900X and the Ryzen 9 7900X3D are not meant for those on a tight budget. These CPUs are designed for those who demand top-of-the-line performance and are willing to pay a premium for it. Precision Boost Overdrive requires a compatible AMD Ryzen Threadripper, 3rd Gen AMD Ryzen processor, or Ryzen 5000 Series processor and a motherboard compatible with one or more of these processors. 2nd Gen AMD Ryzen processors including the Ryzen 3200G processor are not compatible with Precision Boost Overdrive. Because Precision Boost Overdrive enables operation of the processor outside of specifications and in excess of factory settings, use of the feature invalidates the AMD product warranty and may also void warranties offered by the system manufacturer or retailer. GD-135.The Ryzen 9 7900X3D and Ryzen 9 7900X are both high-end desktop processors from AMD, both based on the Zen 4 architecture and manufactured on the TSCM 5nm process node. AMD has confirmed that each chiplet of the 7900X3D contains 6 active cores, ensuring a balanced configuration across the processor. This eliminates any uneven setups where, for instance, one chiplet would contain 8 cores with 3D V-Cache while the other has only 4 cores without it.
