Features of AMD Ryzen 5000 Series Processors

This section explains the features of AMD Ryzen 5000 series processors.

Key points from performance improvements to differences from the previous generation are summarized in an easy-to-understand way.

Architecture Evolved from Zen 2 to Zen 3

Starting with the Ryzen 5000 series, the architecture has evolved from Zen 2 to Zen 3.

Although the manufacturing process remains at 7nm, internal structural improvements have increased performance by about 20%.

Redesigned Core Configuration and Cache

In Zen 2, each CCD (Core Chiplet Die) had two 4-core CCXs (Core Complexes), each with 16MB of L3 cache.

However, this structure sometimes caused latency when cores in different CCXs communicated.

On the other hand, Zen 3 revised this CCX structure, integrating all 8 cores in a CCD into a single CCX.

As a result, all 8 cores can now share 32MB of L3 cache, greatly speeding up data access between cores.

This change brings a noticeable performance boost, especially in gaming and single-threaded performance.

However, some models have 12 or 16 cores, and since they have two CCDs, there is still some latency, but performance has improved compared to before.

Significant IPC Improvement

In Zen 3, instruction prediction and execution efficiency have greatly improved.

Improvements in branch prediction accuracy, instruction scheduler optimization, enhanced load/store units, and improved integer/floating-point units have increased IPC (instructions per clock) by about 19%.

This means Zen 3 can process more tasks at the same clock speed, which is effective for daily tasks, gaming, and creative work.

Introduction of 3D V-Cache Models

3D V-Cache is a technology that stacks L3 cache (temporary data storage) vertically to increase capacity compared to conventional CPUs.

While normal CPUs place cache on a flat plane, 3D V-Cache stacks L3 cache like building floors.

Thanks to this, for example, the Ryzen 7 5800X3D has increased L3 cache from 32MB to 96MB.

AMD Ryzen CPUs that support this technology have a “3D” at the end of their name (e.g., Ryzen 7 5800X3D), so it is easy to identify if they support 3D V-Cache.

This large L3 cache especially boosts gaming performance.

Depending on the game, since performance depends heavily on CPU cache, increasing cache size directly improves load times and frame rates.

When talking about game frame rates, many people think of GPU performance.

The GPU is the most important part, but it is not the only factor.

The CPU gives instructions to the GPU for graphics processing, and some parts of games are processed by the CPU, so CPU performance also matters.

Socket and Chipset: “AM4” and “400/500 Series”

For the Ryzen 5000 series, the socket is “AM4” and the chipset is the “400/500 series”.

This is the same as the Ryzen 3000 and 4000 series, so with a BIOS update, existing motherboards can be used.

However, some entry-level or older motherboards may not support Ryzen 5000 series CPUs.

Therefore, if upgrading from the Ryzen 3000 or 4000 series, check the motherboard’s “CPU support list” to see if it supports the Ryzen 5000 series.

Specifications of AMD Ryzen 5000 Series Processors

This section explains the specifications of AMD Ryzen 5000 series processors by grade.

AMD Ryzen 9 Processors

The changes from the previous generation for AMD Ryzen 9 processors are as follows:

• No change in core and thread count for most models
• Clock speed varies by -0.5 to 0.2 GHz
• Maximum operating temperature changed from 95°C to 90°C
• Ryzen 9 5900XT has increased from 12 cores/24 threads to 16 cores/32 threads, and L2 cache increased from 6MB to 8MB

AMD Ryzen 7 Processors

The specifications of AMD Ryzen 7 processors, and the changes from the previous generation, are as follows.

• No change in core and thread count
• Clock frequency varies by -0.2 to +0.2 GHz
• Maximum operating temperature reduced from 95°C to 90°C

AMD Ryzen 5 Processors

The specifications of AMD Ryzen 5 processors, and the changes from the previous generation, are as follows.

• No change in core and thread count
• Clock frequency varies by -0.1 to +0.3 GHz
• L3 cache increased from 8 MB to 16 MB on some models
• Default TDP reduced from 95 W to 65 W on some models
• Maximum operating temperature reduced from 95°C to 90°C

AMD Ryzen 3 Processors

For AMD Ryzen 3 processors, there are no models that can be directly compared with the previous generation, so the specifications are summarized below.

Benchmark Comparison of AMD Ryzen 5000 Series Processors

This section compares various data for AMD Ryzen 5000 series processors.

Benchmark Scores

The table is sorted in descending order of benchmark scores, and the grades are organized as Ryzen 9, 7, and 5.

Among them, Ryzen 9 stands out with the highest performance, followed by Ryzen 7 and 5 in a gradual order.

Looking at each grade, the 3D V-Cache (3D) models have high performance.

Their scores are higher than the regular models with the same name, and especially in gaming, where large cache size is beneficial, they show strong performance.

Also, models with integrated GPUs, such as “G” and “GE”, generally have lower scores.

This is partly because they have integrated GPUs, but also because their TDP is lower, so their benchmark scores are not as high.

Cost Performance

Cost performance is calculated as the score per 100 yen, sorted in descending order.

Some prices are unknown, but Ryzen 5 generally has the highest cost performance.

Next are Ryzen 7 and 9, so as performance increases, prices rise and cost performance drops, which is a general trend.

Also, “X3D” models are more expensive due to the cost of increasing cache size, so their cost performance is lower.

Power Efficiency

Power efficiency is calculated as the score per default TDP, sorted in descending order.

This can be helpful for those who want to build a power-saving custom PC.

However, note that this is calculated from the default TDP, not the maximum TDP when clock speed is temporarily increased by Precision Boost.

The 35W models are at the top, followed by the 65W models.

For the 105W models, there is a split between those with high scores and high power efficiency, and those with low scores and low efficiency.

From a power efficiency perspective, the “GE” models are good, but GE models are mainly for pre-built desktop PCs (OEM) and are not generally available for purchase, so the next best options are Ryzen 9 and 7 models.

Summary: The 5000 Series Features Zen 3, 3D V-Cache Models, and Revised CCX Structure!

This article explained in detail the features, specifications, and benchmark results of AMD Ryzen 5000 series processors.

Here is a summary of the key points:

The Ryzen 5000 series has improved processing efficiency thanks to the switch to Zen 3 architecture.

Additionally, the optimization of the CCX structure and the introduction of 3D V-Cache models have enabled high performance for a wide range of uses, from gaming to creative work.

With a wide lineup, it is possible to choose the best model for gaming, power saving, or cost performance, depending on the purpose and budget.

The flexibility to meet the needs of everyone from beginners to advanced users is the appeal of the Ryzen 5000 series.
