![]() ![]() The $599 Ryzen 9 7900X3D also noses into the conversation at $150 more than the 7800X3D, but it is slower than the 7800X3D in gaming and its proximity to the 7950X3D's pricing makes this a tough chip to recommend at its current pricing. However, we don’t feel these outliers represent a meaningful weakness of the 7800X3D - this isn't uncommon with immature launch BIOSes and drivers. The dual-compute-chiplet X3D chips also hold a significant advantage in the 99th percentiles in Cyberpunk 2077 over single-chiplet models. This stems from lower-than-expected 99th percentile framerates with the 7800X3D in Hitman 3 at 1080p, which we’ll analyze deeper as time permits. The 7950X3D also takes the lead over the 7800X3D in 99th percentiles at the 1080p resolution, but we don’t see that same trend with 1440p. The Ryzen 9 7950X3D has a bit more overclocking headroom than the 7800X3D at 1080p, but that isn't worth the stiff premium. Most gamers will be best served running the chip at stock settings. ![]() Engaging the DDR5-6000 Expo profile on our memory kit (labeled ‘Expo’ in the charts) yielded a mere ~2% speedup, and combining the faster memory with the auto-overclocking Precision Boost Overdrive and undervolting (labeled as PBO and UV) resulted in an underwhelming total gain of 3%. Overclocking the Ryzen 7 7800X3D was a mixed bag. As you'll see on the following page, the 7800X3D can't keep pace with the 13700K in productivity apps. The $417 Core i7-13700K trails the 7800X3D by ~ 14%, but its lower price tag and more balanced performance in productivity applications might make it attractive if you're looking for more than a chip optimized specifically for gaming. Overall, the 7800X3D will run faster and cooler than the 13900K in every gaming scenario, but the 13900K is a far more adept all-rounder. In contrast, the Ryzen 7 7800X3D runs cool and didn't exceed 90W in our testing. ![]() The Core i9-13900K requires exceptionally aggressive accommodations for overclocking. The Ryzen 7 7800X3D is 12% faster in 1080p gaming than the $580 Core i9-13900K, and overclocking only narrows that to 8%. The biggest difference between these two chips is the price tag and the number of cores the 7950X3D costs $250 more and has twice the number of cores, which will help in productivity workloads. Interestingly, the 7800X3D increases its lead over the 7950X3D to 2.5% at 1440p, but this is still a very close contest that falls into the imperceptible range. The 3D V-Cache tech puts AMD’s X3D chips in a league of their own, so the $449 7800X3D contends with the $699 16-core Ryzen 9 7950X3D for the lead - a victory it wins by a mere 1% in its stock configuration. The 3D V-Cache tech can also lead to slower performance in productivity applications, as you'll see on the following page. The $449 Ryzen 7 7800X3D is an incredibly fast gaming chip but be aware that the 3D V-Cache doesn’t accelerate all titles equally, so you’ll have to assess the trends in the individual game benchmarks below. We simplified the first slides by excluding the overclocking configs, while the remainder contains the full roster of tested configurations. ![]()
