AMD has finally announced the 7000 X3D series CPUs, it feels like we have waited a long time for the next iteration of AMD’s 3D V-Cache technology. This time, the V-Cache belongs to a Zen 4 CPU, three of them to be exact. Today we’re looking at the 7900X3D and how it stacks up against the previous-gen’s 5800X3D. This is Ryzen 9 7900X3D vs Ryzen 7 5800X3D.

Now read: Ryzen 7 7800X3D vs Rzyen 7 5800X3D

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

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

Update: AMD has announced the official release date of the Ryzen 9 7900X3D. It will be on February 28th, 2023. This will be alongside the Ryzen 9 7950X3D, however, the 7800X3D will not be available until April 6th.

Ryzen 9 7900X3D vs Ryzen 7 5800X3D: Specifications

Here we will look at the specification of the two CPUs we’re analyzing today.

Ryzen 9 7900X3D

The 7900X3D looks pretty normal until you notice the massive cache. This is the middle of the three new X3D CPUs in the Ryzen 7000 series, so we expect it to perform much better than the 5800X3D, but worse than the 7950X3D.

Ryzen 7 5800X3D

Once crowned the “fastest gaming CPU” we have seen the 5800X3D overcome the toughest opponents in gaming. This includes the 5950X and the Core i9-12900K, formidable opponents. Yet the 5800X3D managed, thanks to its massive Cache.

With all that out of the way, we will compare a few specifications. for the sake of time and an easy read, we’re only going to mention the things that have changed.

With that out of the way, let’s get into the specification comparison.

Ryzen 9 7900X3D vs Ryzen 7 5800X3D: Specification comparison

Here we’re going to discuss all the differences between the 7900X3D and the 5800X3D. To save you some time, we’re only going to discuss the differences.

Architecture

When comparing Zen 3 and Zen 4, many differences deserve their own discussion; however, here is a brief summary.

The main difference between Zen 3 and Zen 4 is that Zen 4 makes use of a new 5nm process technology, allowing smaller transistors resulting in a greater density. Performance and energy efficiency both increased as a result. Additionally, compared to Zen 3, Zen 4 offers even more IPC (instructions per cycle) improvements. This indicates that the Zen 4 core is more potent in addition to being more effective.

Core count

The Ryzen 9 7900X3D has a much higher core count, making it better for multitasking.

More CPU cores allow for better performance because the processor can handle more tasks concurrently, increasing processing speed. The CPU’s processing unit, or core, is in charge of carrying out instructions.

When a computer is running several programs or processes, the CPU can divide the workload among its cores, enabling each core to perform multiple tasks at once. This is called multithreading, and it can significantly boost CPU performance.

Core speed

The 7900X3D has a much higher core boost speed, allowing better performance in general. But CPU core speed has a special bearing on gaming performance. The faster your CPU core the better it will be at gaming, providing it’s in the same, or better, CPU architecture.

The CPU clock speed, also known as Core speed, is the rate at which a CPU completes one instruction cycle per second. It is measured in Hz. One gigahertz (GHz), or one billion cycles per second, is used to measure the broader CPU speed. The more cycles the processor can complete in a given amount of time, the faster the clock speed, which may result in better performance.

The internal clock, which creates a series of pulses to synchronize the processor’s operations, controls the clock speed of the processor. The manufacturer determines the clock speed, but the user can modify it using the computer’s BIOS or UEFI settings. 

The faster the CPU can complete the instruction cycle, the faster the CPU can process. Speed is one of the most important factors when trying to measure a CPU’s performance. However, other factors such as the number of cores, the size of the cache, and the microarchitecture can also have a significant impact on performance.

TDP

TDP stands for thermal design power, and in this case, the 7900X3D has a much higher TDP than the 5800X3D.

The term TDP stands for “Thermal Design Power” and is a measure of the maximum amount of heat that a CPU or other component is designed to dissipate under normal operating conditions. The TDP rating of a CPU is typically given in watts and reflects the amount of power that the processor is expected to consume, which in turn determines the amount of heat that is generated.

The TDP rating is an important consideration when selecting a CPU as it can affect factors such as cooling requirements, system stability, and overall performance. CPUs with higher TDP ratings typically require more robust cooling solutions to keep temperatures under control, which can result in higher system costs.

CPUs with lower TDP ratings may consume less power and generate less heat, making them more suitable for use in compact or low-power systems. In summary, TDP is a useful metric for understanding the thermal characteristics of a CPU and its overall power requirements, which can impact system design and performance.

Ryzen 9 7900X3D vs Ryzen 7 5800X3D: Gaming

We are aware that the 5800X3D has impressive gaming performance, but will the 7900X3D outperform it? The chances look promising, as the Zen 4 core is significantly more powerful than the Zen 3 core. The Zen 4 core boasts enormous IPC improvements that are highly beneficial for single-core workloads like gaming.

Unlike the 5800X3D, which was restricted, the 7900X3D is not so limited since the 7000X3D series is unlocked for automatic overclocking. This means we should expect significant performance gains with the 7900X3D in gaming workloads compared to the 5800X3D.

Cache plays a crucial role in gaming performance, and with the 7900X3D having a much-improved cache with a larger capacity, we should anticipate a boost in gaming performance.

Ryzen 9 7900X3D vs Ryzen 7 5800X3D: Price

We fully expect the Ryzen 9 7900X3D to cost a lot more than the 5800X3D.

Although we do not know the official price yet, we expect the 7900X3D to cost from $500 – $600 Meanwhile you can pick up the Ryzen 7 5800X3D for anywhere between $300 and $370.

You also have to consider the upgrade cost to AM5, to support the 7900X3D you’ll need an all-new motherboard and a fancy set of DDR5 memory, none of which are cheap right now.

Ryzen 9 7900X3D vs Ryzen 7 5800X3D: Conclusions

The Ryzen 9 7950X3D is clearly the better CPU when it comes to day-to-day and gaming workloads. Both of these CPUs are formidable but on different platforms.

The 5800X3D is the best of the AM4 platform and saves you the massive cost to upgrade to AM5. This is the saving grace of the 5800X3D. If you wanted to shoot for the Ryzen 9 7900X3D, you’d need a new motherboard, new RAM, and a new CPU, obviously. So the 5800X3D is great for saving a buck or two whilst getting decent performance. But the 7900X3D is the CPU you want if you’re after power.

Do not purchase any of these CPUs for any kind of process-heavy, or multithreaded workloads. These are not the CPUs for you. We hope you enjoyed our AMD Ryzen 9 7900X3D vs Ryzen 7 5800X3D article.
