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.

Why the new AMD Ryzen 7000 processors for the AM5 socket are currently not a good deal
Posted by Stefan on 2022-10-11
At the end of September 2022, the time had come: AMD presented its latest desktop processors called AMD Ryzen 7000. Initially, 4 processors with 6 to 16 CPU cores were released.

The new socket AM5 (LGA 1718) is used for the first time, which is intended to replace the very durable socket AM4 introduced in 2017 as AMDs mainstream platform. This includes (depending on the chipset) PCIe 5.0 support as well as the exclusive use of DDR5 memory on all AM5 mainboards.

Officially, DDR5-5200 is the maximum, but with AMDs EXPO Technology which is similar to Intel's XMP 3.0, AMD now also has a solution for easy overclocking of the main memory. AMD itself names DDR5-6000 as the sweet spot for the new AMD Ryzen 7000 processors.

AMD Ryzen 5 7600X and AMD Ryzen 7 7800X are coming in September
Posted by Stefan on 2022-06-20
After we published a performance assessment of the AMD Ryzen 9 7950X last week, the well-known AMD leaker Greymon55 has now posted more informations via Twitter.

He predicts the first four models of the new Zen 4 desktop generation, which AMD would like to present at the end of 2022. There is also an alleged release date of September 15, 2022.
AMD Ryzen 9 7950X - Cinebench R23 Benchmark projection
Posted by Stefan on 2022-06-10
We give you a preview of AMD's new Zen 4 desktop processors and calculate the performance of the AMD Ryzen 9 7950X top model for the new AM5 socket. The performance data and other technical details come directly from the press kit that AMD released as part of its Financial Analyst Day on June 9, 2022.

Up to 15 percent more single-core performance and 35 percent more multi-core performance of the 16-core model are realistic !


the CPU comparison between the Intel Core i9-11900K and the AMD Ryzen 9 5900X shows a slightly higher raw IPC performance on the side of the AMD Ryzen 9 5900X. However, due to the higher single-core clock of the Intel Core i9-11900K, Intel can neutralize this disadvantage and so both desktop processors are about the same in single-core benchmarks.

If applications or benchmarks can use all CPU cores of the processors, Intel's 11th generation Core i9 only sees the rear lights of the AMD Ryzen 9 5900X. This can set itself apart from the Intel Core i9 by between 25 and 30%, which is due to the significantly higher number of cores of 12 (24 threads) compared to only 8 (16 threads) of the i9.

Actually, Intel wanted to manufacture the "Rocket Lake S" processors with a new architecture in 10 nm. Presumably due to delivery or production problems, Intel has decided to implement a backport to the tried and tested, but outdated 14 nm production. This is probably the reason why Intel has given the "Rocket Lake S" processors a maximum of 8 CPU cores.

AMD has more room here and can implement up to 16 CPU cores on the AM4 socket. The successor socket should even come with twice the number of CPU cores. New in the Intel Core i9-11900K is the support of PCIe 4.0, which AMD has supported since the previous generation (Ryzen 3xxx). This allows new M.2 SSDs to be connected to the system very quickly. Transfer rates of 7.5 GB / s are possible via four PCIe 4.0 lines.

Both CPUs support 128 GB of RAM of the DDR4-3200 type in two memory channels and achieve transfer rates of approx. 55-60 GB per second. If you want to use faster memory, you can do so with both processors. Intel uses the so-called XMP overclocking profiles that AMD uses with D.O.C.P. similarly supported. Manual overclocking is of course also possible. Both processors manage up to DDR4-3600 without any problems.
