AMD Ryzen 7 9800X3D Review: Devastating Gaming Performance 🎮🔥
El Ryzen 7 9800X3D de AMD, que cuesta $480, viene equipado con ocho núcleos y 16 hilos, junto con una nueva versión de la tecnología 3D V-Cache de la empresa, que potencia los juegos de manera impresionante. Se posiciona como el procesador más rápido para gaming en el mercado, y de manera contundente. 🏆
AMD afirma que este chip es un 20% mejor que el último modelo insignia de Intel y un 8% más rápido que el Ryzen 7 7800X3D de la generación anterior. Sin embargo, nuestras pruebas demuestran que supera al modelo insignia actual de Intel, el Core 9 285K, por un asombroso 35% en promedio en nuestra batería de pruebas. Incluso supera al chip de gaming Intel's fastest, the Core i9-14900K, by an equally incredible 30% on average. 🚀
Of course, improvements will vary depending on the title due to the particularities of the technology 3D V-Cache. Aun así, registramos un rendimiento increíble que consolida firmemente al Ryzen 9 9800X3D como el mejor CPU para gaming. 💪
AMD logró esta hazaña aprovechando su tecnología 3D V-Cache ya probada, que utiliza un chiplet de caché L3 apilado verticalmente de 64 MB para mejorar el rendimiento en juegos. Para mejorar aún más el desempeño, AMD movió el chiplet de caché desde la parte superior del procesador hacia abajo, ofreciendo así un mayor margen térmico. Esto permite tasas de reloj más altas, mientras que la caché adicional desbloquea el máximo performance of Zen 5 architecture. 🔥📈
As we are used to with X3D processors optimized para gaming, no todos los juegos se beneficiarán de la tecnología, y algunos son incluso ligeramente más lentos (1 a 2%) que el modelo de la generación anterior. No obstante, el chip mejora significativamente las tasas bajas del 1% incluso en esos títulos. Las tasas bajas del 1% más altas también ayudarán cuando estés limitado por la GPU, como al jugar con resoluciones más altas. 🎯
AMD has now enabled full overclocking for the 9800X3D as well, which we’ve tested, allowing you to squeeze out more performance in both gaming and productivity work. Speaking of which, the new design also helps eliminate some of the large productivity work penalties that often come with using a gaming-optimized X3D processor, allowing the 9800X3D to match, and sometimes even outperform, a comparable eight-core Ryzen 9000 CPU in a variety of productivity workloads. 💻⚡

💥 The Ryzen The 9800X3D, priced at $480, is AMD's only launch today and will be available in stores tomorrow. This chip is a lifesaver for fans of the gaming 🎮, who faced not one, but two disappointing chip releases this year.
La serie Ryzen 9000 de AMD, impulsada por Zen 5, debutó a principios de este año con ganancias de rendimiento en gaming poco impresionantes. Sin embargo, como verás en nuestras pruebas recientes para esta reseña, las últimas actualizaciones de firmware y un ajuste en Windows han logrado exprimir más rendimiento. Intel también lanzó su esperada serie Arrow Lake Core Ultra just two weeks ago, but those chips failed to match the gaming performance of their previous-generation chips. 😟 Unfortunately, there's no obvious solution in sight, which bodes well for a disappointing year for gaming chips.
The Ryzen 7 9800X3D completely changes the landscape, bringing to market a chip of gaming de primera calidad a un precio razonable dadas sus capacidades. Este chip se adapta a las placas madre AM5 existentes y no requerirá los costosos componentes complementarios, como kits de RAM de alta velocidad, potentes sistemas de refrigeración y placas madre necesarias para extraer el máximo rendimiento de otros chips de gama alta. Mientras tanto, Intel parece totalmente incapaz de contrarrestar la technology AMD's 3D V-Cache, even after two and a half years and three generations of chips, since it debuted with the now legendary Ryzen 7 5800X3D. 🔍
Let's take a look at the tech, and then move on to the surprisingly good gaming benchmarks. 📈

The eight-core, 16-thread Ryzen 7 9800X3D debuts at a price of $1,480, which is $1,430 more than the launch price of the Ryzen 7 7800X3D. 💰 The 9800X3D features a 120W TDP and offers 500 MHz higher base frequencies and 200 MHz higher boost clocks than the previous generation, the Ryzen 7 7800X3D with technology Zen 4. 🚀
The 9800X3D’s 5.2GHz boost is impressive, but it lags behind the direct Zen 5 comparable, the eight-core Ryzen 7 9700X, by 300MHz. However, AMD has compensated with a 900MHz higher base frequency, allowing the 9800X3D to outperform the 9700X in some multi-threaded workloads, as you’ll see in our benchmarks on the following pages. 📊
Like previous-gen models, the Ryzen 7 9800X3D does not include a cooler. AMD recommends a liquid cooler of at least 240-280mm (or equivalent). ❄️ The processor maintains the same maximum temperature of 95°C (TjMax), but the new L3 cache chiplet design allows the chip to operate at higher frequencies for longer (improved boost residency), resulting in greater performance gains within the same TDP. 💪
The Ryzen 7 9800X3D is fully overclockable: you can adjust the CPU cores, processors, and memory to your liking. While multiplier-based overclocking is available, as we've seen with other Zen 5 processors, most users with conventional cooling will be better off using the auto-overclocking feature. Precision Boost Overdrive (PBO). 🔧 We have extensive testing with this feature enabled on the following pages. 🧪
Additionally, AMD has improved memory support to DDR5-5600 from the DDR5-5200 found on the previous-generation 7800X3D. 🖥️
AMD Ryzen 7 9800X3D Architecture
In the illustrations above, you can see AMD's original approach with its technology 3D V-Cache. With previous designs leveraging Zen 3 and Zen 4 architectures, AMD stacked an additional chiplet of L3 SRAM directly in the center of the compute chiplet (CCD) to isolate it from the heat-generating cores. 📊 We've covered the details of the first generation of this technology [aquí](#). AMD utilizó tecnología de unión híbrida para conectar el chiplet de caché al chip de cálculo subyacente. Esto incrementó la capacidad de caché a 96MB, mejorando el rendimiento en aplicaciones sensibles a la latencia, como los videojuegos. 🎮
AMD placed the chiplet and several structural silicon pieces on top of the compute chip, but as we demonstrated with thermal throttling tests of the Ryzen processor 9 7950X3D, el chiplet de caché y las láminas de silicio estructural actuaron como una manta térmica que obstaculizó la transferencia de calor eficaz, esencialmente atrapando el calor residual. 🌡️ Como resultado, AMD limitó el voltaje y el rango de frecuencia efectivos del chip equipado con 3D V-Cache para controlar la generación de calor. En pocas palabras, el chip se calentaba demasiado y, por lo tanto, tenía que funcionar más lento. 🐢
AMD has now placed the cache chiplet under the die to alleviate thermal challenges, placing the compute die closer to the thermal interface material, IHS, and eventually the CPU cooler. This improves the amount of performance computing that AMD can squeeze out of the 120W TDP envelope, and also improves boost residence/duration. However, this brings a new set of challenges — this design requires AMD to route power and TSV signals for the entire chip through the underlying L3 cache chiplet. 🔥💻
The new L3 cache chiplet is based on the same 7nm SRAM-optimized node process that AMD used in the previous two generations of 3D V-Cache technology, in a technique AMD now calls its «Second Generation 3D V-Cache» (a bit of an odd branding choice, as this is actually the third refinement of the technology.) As before, AMD thins both the L3 cache chiplet and the 4nm compute die (N4P) to meet standard processor package Z-height requirements. 💾🔧
AMD uses the same copper-to-copper hybrid junction with a 9-micron protrusion pitch to join the two dies together. The chiplet now spans the entire bottom of the compute die, thus eliminating the need for the structural silicon shims. AMD isn't sharing the L3 cache chiplet size or transistor density, but the compute die measures 70.6 mm², so it's a safe bet that's the size of the cache chiplet as well.
This is much larger than the 36mm² L3 cache chiplet used for the Zen 4 X3D models, despite using the same process node and 64MB L3 capacity. AMD likely has a lot of 'empty' silicon in the cache chiplet that's simply there for structural support, without the need to add separate shims. 🛠️📏

🌟 Naturally, AMD has to feed more power and signal through the TSVs in the L3 cache chiplet, which now acts as a sort of interposer, down to the compute die. 💡 AMD mentions that the power TSVs are distributed across the SRAM die to feed the compute die above. 🔋 The additional power TSVs are distributed in areas not used for other functions (presumably as more cache storage), which should at least partly explain the larger size. 📈

AMD mentions that accesses to the chiplet L3 cache incurs the same four-cycle penalty as the previous generation. 🕒
We measured an increase in L3 latency of less than a nanosecond compared to the previous generation equipped with 3D V-Cache, such as the Ryzen 7 7800X3D, which is within the expected variability. 📊
AMD claims that bandwidth between the processing core and the L3 chiplet is similar to the previous generation, at 2.5 TB/s, although bandwidth varies with clock speeds. 📈
Now, both main memory and I/O accesses must go through the L3 cache chiplet. As can be seen from the measurements above, there is a marked increase in DDR5 latency compared to the standard Ryzen 7 9700X and the Ryzen 7 7800X3D. 🚀
AMD claims there is no increase in I/O latency due to bypassing the cache chiplet. 🛡️ We are looking into further details on this. Naturally, any increase in memory latency is undesirable. However, we expect this to have a minimal impact on overall performance thanks to the increased amount of L3 cache minimizing main memory accesses in certain scenarios. 🔍
