A feature of the Ryzen 7000X3D series is that it incorporates 3D V-Cache technology. As the name suggests, 3D V-Cache technology is a technology that increases the memory cache installed in the CPU, and by pasting SRAM (V-Cache) for cache on the CPU, the capacity of the L3 cache increases. The 3D V-Cache technology itself is installed in the ' Ryzen 7 5800X3D ' released in April 2022.
The Ryzen 9 7950X3D features an asymmetric chiplet design where one of the CCDs (CPU dies) is a regular Zen4 CCD while the other Zen 4 CCD features a 64MB V-Cache. This means that one CCD has a 32MB L3 cache and the other has a 96MB L3 cache.
Also, attaching a V-Cache to the CCD limits the maximum clock speed, limiting it to around 5.25GHz. This V-Cache is the reason why the base frequency of Ryzen 9 7950X3D is slightly lower than that of Ryzen 9 7950X. Therefore, AMD designs to access the appropriate CCD according to the processing of the application. By using a CCD with V-Cache and an ordinary CCD, it is balanced so that performance can be maximized when performing multiple tasks simultaneously. In addition, 'AMD PPM Provisioning File Driver' has a function to automatically distinguish CCDs that can process at higher speed during game operation, pause one CCD and perform processing on the other.
AnandTech, a hardware-related news site, shows the screen below where the background process is checked with the task manager, and the item 'AMD 3D V-Cache Performance' is displayed.
The environment when AnandTech tested Ryzen 9 7950X3D is as follows.
| CPU | Ryzen 9 7950X3D |
| motherboard | GIGABYTE X670E Aorus Master (BIOS 813b) |
| memory | G.Skill Trident Z5 Neo 2x16GB DDR5-5200 CL44 |
| cooling system | EK-AIO Elite 360 D-RGB 360mm AIO |
| storage | SK Hynix 2TB Platinum P41 PCIe 4.0 x4 NMve |
| power supply | Corsair HX1000 |
| GPUs | AMD Radeon RX 6950 XT (Driver ver31.0.12019) |
| OS | Windows 11 22H2 |
The peak power when using Microsoft Office is measured below. Ryzen 9 7950X (red) is about 222W, while Ryzen 9 7950X3D (orange) is about 145W, which shows that the power consumption is considerably reduced.
And the performance when using Word, Excel, and PowerPoint is shown in the bar graph below, showing that the longer the graph, the better the performance. You can see that the Ryzen 9 7950X (red) outperforms the Ryzen 9 7950X3D (orange) other than 'batch photo editing' by
Below is a graph summarizing the rendering time in 3D software Blender. A lower number indicates better performance. Looking at this, Ryzen 9 7950X (red) has a slightly shorter rendering time than Ryzen 9 7950X3D (orange), but its performance is almost the same.
Below are the benchmark results for compression, decompression, and combining with 7-Zip. In both cases, the higher the number, the better the score. Ryzen 9 7950X3D (orange) scores slightly better for compression, and Ryzen 9 7950X (red) scores slightly better for decompression and combining, but the performance is about the same.
In addition, AnandTech benchmarks with CineBench, Geekbench 4.0 and Geekbench 5. Cinebench scores CPU performance with single thread (ST) and multithread (MT) at R10, R11.5, R15, and R20. The result is the victory of Ryzen 9 7950X (red) in all.
Geekbench 4.0 looks like this. Ryzen 9 7950X (red) scores higher than Ryzen 9 7950X3D (orange) in both single-threaded (ST) and multi-threaded (MT).
Ryzen 9 7950X (red) also won Ryzen 9 7950X3D (orange) in the results of Geekbench 5 as well.
AnandTech measures the average drawing frame rate (FPS) and the 5th percentile FPS because the Ryzen 9 7950X is a CPU for gaming PCs. With the 4K resolution of
Ryzen 9 7950X3D (orange) wins both
Ryzen 9 7950X3D consumes less power than Ryzen 9 7950X, and in terms of gameplay performance, Ryzen 9 7950X3D outperforms Ryzen 9 7950X in most titles. However, the Ryzen 9 7950X has shown better performance in some titles, not in all titles. In addition, there were many cases where Ryzen 9 7950X outperformed Ryzen 9 7950X3D in computing other than gameplay.
From a series of results, AnandTech said, ``Ryzen 9 7950X3D has excellent performance in some tasks such as rendering and encoding in addition to gameplay, but overall, Ryzen 9 7950X is still the most performing AMD CPU. It's clear that the system is superior,' he said.
Also, it seems that the execution of the benchmark mode of the simulation game ' Factorio ' could not be detected correctly, probably due to compatibility issues between the AMD PPM Provisioning File Driver and the Xbox Game bar. AnandTech analyzes that this is due to forcing the Ryzen 9 7950X3D to perform calculations using a CCD with V-Cache. However, the AMD PPM Provisioning File Driver works fine in most games, arguing that AMD's strategy of installing V-Cache on one CCD was largely correct.
AnandTech said, ``Ryzen 9 7950X is cheaper than Ryzen 9 7950X3D at the time of writing, and Ryzen 9 7950X has a better balance between gaming and computing performance.However, titles that are often played for gaming purposes If you know that will benefit from 3D V-Cache, the Ryzen 9 7950X3D is the better choice.'
