The $449 8-core Ryzen 7 7800X3D is the new high-performance gaming champion for desktop PCs. The Ryzen 7 7800X3D is significantly cheaper than its competitors, but is still averaging 12% faster in games and up to 40% faster in some titles than Intel’s $580 flagship Core i9-13900K, making it currently the fastest gaming CPUs. Available — AMD’s own $699 16-core Ryzen 9 7950X3D. AMD’s Exotic 2nd Gen 3D V-Cache Technology Powers The 7800X3D’s Incredible Gaming Performance By Boosting The Chip’s L3 Cache Capacity To An Incredible 96MB Via 3D Stacked Chiplets and guarantees the top spot on our list of the best CPUs for gaming.
The Ryzen 7 7800X3D has big shoes to fill — with its first-generation 3D V-Cache (X3D) chip, Zen 3, the Ryzen 7 5800X3D has become the go-to chip for affordable, high-performance gaming. rice field. And still loved. Like its predecessor, the Ryzen 7 7800X3D is specifically designed to blast CPU-limited games with unprecedented levels of performance, but the tech won’t speed up every game. models that may not perform as well as the standard Ryzen 7000 in some productivity applications.

However, while the 5800X3D used the Zen 3 architecture and 7nm process, the 5nm Ryzen 7 7800X3D is powered by the new Zen 4 architecture with a much higher peak boost of 5.0 GHz to reduce the performance disparity. AMD has also unlocked basic overclocking and undervolting for the 7800X3D. This is another advantage over previous generation models.
Simplicity is a key advantage of the Ryzen 7 7800X3D. AMD has expanded its X3D family with the $699 16-core Ryzen 9 7950X3D with Zen-4 and the $599 12-core Ryzen 9 7900X3D. These heavier models work hand in hand with more cores to focus on productivity to deliver incredible gaming performance, but AMD’s revolutionary new thread target technology to extract the best performance. It has multiple computing chiplets that require
In contrast, the Ryzen 7 7800X3D has a single compute chiplet and should offer a much more plug-and-play experience without the need for additional thread targets/software handholding. Simple, fast, and efficient are the goals, and AMD’s chips pretty much deliver on those goals (I ran into some major stumbling blocks described on the test setup page).

Here’s a quick rundown of the most important gaming benchmark averages and tests in productivity applications, but head over to the rest of the tests on the next page for individual benchmark results and overclocking configurations.
AMD’s pricier Ryzen 9 7950X3D and its sibling 7900X3D received critical acclaim, but the company has held off the much cheaper Ryzen 7 7800X3D until April 6th. At $250 less than the flagship, there’s not much reason to buy the flagship if you’re only interested in gaming. In fact, if your best gaming performance is your only concern and you have the budget, we found that the Ryzen 7 7800X3D doesn’t have much room for other chips. Much better than other chips. That said, Intel isn’t sitting on the sidelines either, as the Raptor Lake alternative has its own advantages. Let’s see how the chips stack up in the gaming benchmarks on the next page.

AMD foreshadowed the arrival of the Ryzen 7 7800X3D when it first announced the Ryzen 7000 lineup with a prominent ‘7800X’ sized hole between the Ryzen 7 7700X and the Ryzen 9 7900X. In terms of gaming performance, the Ryzen 7 7800X3D slot is on par with Intel’s $580 24-core 32-thread Core i9-13900K but the $417 16-core 24-thread Core i7-13700K. Price and performance terms in productivity applications.
The 7800X3D looks somewhat similar to the Zen 3 powered Ryzen 7 5800X3D, both chips featuring 8 cores, 16 threads and 3D V-Cache tech, but the similarities don’t stop there. The Ryzen 7 7800X3D steps up to the Zen 4 architecture, featuring a 500 MHz higher boost frequency of 5.0 GHz and an 800 MHz higher base clock of 4.2 GHz, all of which offer much better performance and more diverse applications in gaming. Offers. As you can see on the next page, AMD could have clocked his 7800X3D higher, but chose to stop at 5.0 GHz.
Among the latest Zen 4 family, the Ryzen 7 7700X is the closest comparison with the same allocation of 8 cores and 16 threads, but lacks the 3D stacking tech and features 300 MHz higher base and 400 MHz higher boost clocks than the 7800X3D. I’m here. That’s because the Ryzen 7 7800X3D features 8 cores on a single compute die powered by his 7nm SRAM slice of hybrid-bonded L3 cache on silicon. This cache chiplet causes the thermal issues you can read about here, ultimately leading to a voltage limit of 1.1 V and lower peak frequencies than standard chips. This is a necessary adjustment to keep the heat down.
AMD’s 3D V-Cache technology brings the key benefits of chiplet-based design approaches to the 3D by stacking an older, cheaper 7nm process node on top of a core etched in an expensive newer 5nm process technology. into the Like all other 3D V-Cache chiplets, the 3D Stacked SRAM L3 chip weighs 64MB. As a result, the 7800X3D comes with a total of 104MB of cache, of which 96MB is the L3 cache that boosts games. The additional L3 cache chiplet has a peak bandwidth of 2.5 TB/s, which is 25% faster than the previous generation implementation. Learn more about our 2nd generation 3D V-Cache technology here.

All of AMD’s Zen 4 3D V-Cache processors feature a base TPD of 120W and a maximum PPT of 162W, so the 7800X3D is rated at 15/20W. taller than Better than the standard 7700X’s 105W/142W rating. In contrast, the multi-chiplet 7950X3D and 7900X3D have lower power thresholds than comparable chiplets. This is because the additional cache chiplets cause slightly higher operating temperatures that need to be kept within safe limits.
However, the Ryzen 7 7800X3D’s high TDP threshold doesn’t make much sense. As you can see on the next page the chip never approached its rated power limit and the heat was easily tamed. is also lower. The 7800X3D does not come bundled with a cooler. AMD recommends his 280mm or larger water cooler for the Ryzen 7000X3D processor.
Like all Ryzen 7000 chips, the RDNA 2 integrated GPU in the Ryzen 7 7800X3D has 2 compute units, 4 ACEs and 1 HWS. This unit doesn’t have the horsepower needed to benefit from faster CPU cores. It relies entirely on GPU computation. The iGPU does not benefit from 3D V-Cache technology as it sits on the I/O die and does not have access to the L3 cache. So the performance is the same as regular Ryzen 7000 processors (see X3D iGPU for details). test).
While the previous generation Ryzen 7 5800X3D uses the aging AM4 platform with less advanced interfaces like PCIe 4.0 and DDR4 memory, the Ryzen 7 7800X3D supports the latest connectivity technologies like DDR5 and PCIe 5.0. Snaps onto any AM5 motherboard. AMD only allowed memory and Infinity Fabric overclocks on his 5800X3D in the previous generation, but now he allows both Precision Boost Overdrive (PBO) and Curve Optimizer for automatic overclocking. AMD does not yet allow direct frequency overclocking due to the aforementioned voltage limitations imposed by the 3D V-Cache. The next page has many tests using these features. For more information, please visit our overclocking page.
A driver anomaly we reported to AMD caused some issues in our testing, but the Ryzen 7 7800X3D should benefit from the simplicity of its single compute chiplet design.
The Ryzen 9 7950X3D and 7900X3D have two 8-core Core Compute Die (CCD) chiplets paired with a central I/O die, marking AMD’s first introduction of 3D V-Cache technology to a multi-CCD processor. is shown. The image above shows AMD only mounting a single 7nm SRAM chiplet on top of one of its two 8-core CCDs, leaving the other bare. This means that each type of chiplet is perfect for different types of work. 3D V-Cache enabled chiplets are best for cache latency sensitive tasks such as gaming, while standard chiplets are best for workloads that respond best to higher frequencies.
You can read more about AMD’s thread target implementation here, but the key point is that automatically changing the allocation of threads to cores requires four different components working together. about it.
In contrast, we don’t have an image (or render) of the removed Ryzen 7 7800X3D, but it comes with just one of the two small rectangular CCDs seen in the image. It means you don’t need these mechanisms to forward. Since there is only one chiplet, the processor works normally. Let’s see what the performance looks like on the next page.
