V-Ray CPU-Render Benchmark

V-Ray is a 3D rendering software from the manufacturer Chaos for designers and artists. Unlike many other render engines, V-Ray is capable of so-called hybrid rendering, in which the CPU and GPU work together at the same time.

However, the CPU benchmark we used (CPU Render Mode) only uses the system's processor. The working memory used plays a major role in the V-Ray benchmark. For our benchmarks we use the fastest RAM standard approved by the manufacturer (without overclocking).

Due to the high compatibility of V-Ray (including Autodesk 3ds Max, Maya, Cinema 4D, SketchUp, Unreal Engine and Blender), it is a frequently used software. With V-Ray, for example, photorealistic images can be rendered that laypeople cannot distinguish from normal photos.

Monero Hashrate kH/s

The crypto currency Monero has been using the RandomX algorithm since November 2019. This PoW (proof of work) algorithm can only efficiently be calculated using a processor (CPU) or a graphics card (GPU). The CryptoNight algorithm was used for Monero until November 2019, but it could be calculated using ASICs. RandomX benefits from a high number of CPU cores, cache and a fast connection of the memory via as many memory channels as possible. Tested with XMRig v6.x under the operation system HiveOS.

To trade Monero you can register with the crypto broker Kraken.com. We've been customers there for a few years now and have been very satisfied so far.

News and articles for the AMD Ryzen 9 5900X and the AMD Ryzen 9 3900XT


In this comparison, 2 processors of the Ryzen 9 series from the CPU program from AMD compete against each other. The AMD Ryzen 9 5900X is the more recent processor that came on the market in the fourth quarter of 2020, while the AMD Ryzen 9 3900XT was released in the third quarter of 2020.

Both processors are manufactured using the 7 nanometer process, but are based on different manufacturing architectures. The AMD Ryzen 9 5900X is already based on the new "Zen 3" architecture, whereas the AMD Ryzen 9 3900XT is still based on the previous "Zen 2" architecture.

The AMD Ryzen 9 5900X is a processor with 12 cores that supports both hyperthreading and can also be overclocked. The AMD Ryzen 9 3900XT, on the other hand, has 16 cores, but also supports hyperthreading and can be overclocked. The base clock frequency of the processors is 3.70 gigahertz (AMD Ryzen 9 5900X) or 3.50 gigahertz (AMD Ryzen 9 3900XT), and the maximum turbo clock when a core is loaded is 4.80 gigahertz (AMD Ryzen 9 5900X) and 4.70 gigahertz (AMD Ryzen 9 3900XT almost on par. Only the maximum clock when all cores are loaded shows a clearer difference, here the clock frequencies are 4.50 gigahertz (AMD Ryzen 9 5900X) and 4.00 Gigahertz (AMD Ryzen 9 3900XT).

Both processors have 2 memory channels through which RAM modules of the DDR4 type are supported with a clock frequency of up to 3200 megahertz. Overall, both processors support a maximum memory of 128 gigabytes and ECC memory is also supported by both processors.

Since both processors do not have an iGPU, you can connect the graphics card of your choice via the 20 existing PCIe lines.
