The release of the Ryzen 7 7800X3D is finally upon us, we have been waiting a long time for a more budget option to assert itself into the X3D space. We saw the mad success of the revolutionary 5800X3D, but will that success be replicated in the newest generation? Here’s AMD Ryzen 7 7800X3D vs Ryxen 9 7900X3D.

We will look at both of these CPUs comparatively by analyzing the specifications, use cases, and price of each CPU. Since they’re both made primarily for gaming, we will be discussing gaming workloads especially.

For now, let’s take a look at the specifications of each CPU.

Positioned as the intermediate option among the latest X3D processors in the Ryzen 7000 lineup, we anticipate that it will outdo the 5800X3D in terms of performance, yet fall short of the top-tier 7950X3D. It remains to be seen how it will stack up against the Ryzen 7 7800X3D.

AMD Ryzen 7 7800X3D vs Ryzen 9 7900X3D: Specification comparison

Here we will handle the specification comparison of both the Ryzen 7 7800X3D and the Ryzen 9 7900X3D.

CPU architecture

The core architecture refers to the design of the CPU’s internal structure, which determines how many cores it has, how they are arranged, and how they interact with each other. This, in turn, impacts the CPU’s speed, power consumption, and ability to handle different tasks.

For example, CPUs with more cores can handle multiple tasks simultaneously, making them ideal for multitasking and running complex applications like video editing software or 3D modeling programs. On the other hand, CPUs with fewer but faster cores may be better suited for gaming or tasks that require high single-core performance.

Moreover, advancements in core architecture, such as the introduction of new instruction sets, cache designs, and manufacturing processes, can result in significant performance improvements even within the same product line.

Core count

The Ryzen 9 7900X3D has a much higher core count.

CPU core count is essential for gaming performance and overall system performance because it determines how many tasks the CPU can handle simultaneously, allowing for better multitasking and faster processing.

In gaming, the CPU is responsible for handling tasks such as physics calculations, AI computations, and game logic, among others. As games become more complex, they require more processing power, and a CPU with more cores can handle these tasks more efficiently, resulting in smoother gameplay and higher frame rates.

Modern games often require multiple threads to run efficiently, and CPUs with more cores can allocate these threads to different cores, allowing for better multitasking and smoother gameplay.

In addition to gaming, CPUs with more cores can also improve the performance of other applications such as video editing, 3D modeling, and other CPU-intensive tasks. These tasks require significant processing power and benefit greatly from processors with more cores.

However, it is worth noting that simply having more cores does not necessarily mean better performance. Other factors such as clock speed, cache size, and architecture also play a crucial role in determining the CPU’s performance. Therefore, it is essential to consider these factors alongside core count when evaluating a CPU’s performance.

Core speed

Core speed, also known as clock speed, is an important factor in determining CPU performance in both general computing and gaming.

In general computing, the CPU’s clock speed determines how many instructions the processor can execute per second, and a higher clock speed means that the CPU can perform more operations within a given time frame, resulting in faster processing. This is particularly important when running CPU-intensive applications such as video editing software, 3D modeling tools, or data analysis software, where faster processing leads to shorter rendering or calculation times.

Similarly, in gaming, the CPU’s clock speed is a critical factor in determining the performance of the system. In addition to its ability to execute instructions quickly, the CPU’s clock speed affects how fast it can send data to the graphics card, which is crucial for generating high-quality graphics and maintaining high frame rates.

Moreover, the clock speed also affects how quickly the CPU can handle physics calculations, artificial intelligence, and other tasks required for modern games. A faster CPU clock speed can result in smoother gameplay, better frame rates, and shorter load times.

CPU TDP

Thermal Design Power (TDP) is an important factor to consider when choosing a CPU because it indicates the amount of heat that the processor generates under normal operation.

The TDP is measured in watts and represents the maximum amount of heat that the CPU can dissipate using the cooling system. CPUs with a higher TDP typically require more advanced cooling solutions, such as liquid cooling or larger heat sinks, to prevent overheating and maintain stable performance.

When choosing a CPU, it’s important to consider the TDP of the processor because it can affect system stability, noise levels, and power consumption. CPUs with higher TDPs generally require more power to operate, which can increase energy consumption and heat output.

Moreover, CPUs with lower TDPs may have lower clock speeds or fewer cores to reduce power consumption and heat output, which can affect overall system performance.

Therefore, choosing a CPU with an appropriate TDP for your system’s cooling solution and power supply is essential to ensure stable and reliable performance. Additionally, selecting a CPU with a lower TDP can result in quieter operation and lower energy bills, while a higher TDP CPU can provide more performance, but may require additional cooling solutions and consume more power.

Ryzen 7 7800X3D vs Ryzen 9 7900X3D: Gaming performance

The Ryxen 9 7900X3D will definitely beat the 7900X3D in gaming performance, As well as general performance. The 7900X3D has more cores, more threads, and a larger cache. That’s everything you need to make a better CPU.

The reason the X3D processors are so good in gaming workloads is thanks to the 3D V-cache they’re equipped with.

The primary benefit of 3D V-Cache technology is that it can significantly improve gaming performance in Ryzen CPUs. The larger cache size can help reduce the number of times the CPU needs to access main memory, which can reduce memory latency and improve gaming performance.

In games, faster memory access can help improve performance in areas such as texture loading, level loading times, and overall system responsiveness. Additionally, the additional cache can also help with multitasking, allowing the CPU to handle more processes simultaneously without experiencing a slowdown.

Overall, the 3D V-Cache technology can provide a performance boost for gaming and other CPU-intensive tasks, making it a valuable addition for users looking to maximize their system’s performance. However, the impact of 3D V-Cache technology on gaming performance may vary depending on the specific game and the system configuration, so it’s important to consider other factors such as CPU clock speed, core count, and memory speed when choosing a CPU for gaming.

Final word

Either way, both of the CPUs on this list make for mean gaming CPUs, the matter is whether or not you have the budget for them. The 7800X3D is much cheaper than the 7900X3D, and thanks to the recent availability of A620 motherboards, we finally have a budget platform for Ryzen 7000 series CPUs.

The 7900X3D is much faster and much more suited to general workloads where gaming may not necessarily matter. However, we would not recommend getting these CPUs if you’re running anything other than a pure gaming build. If all your PC is designed to do is game, then go ahead. These CPUs are great at one thing, and that’s gaming.

We hope you enjoy your new Ryzen 7000 X3D series CPU.
