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.

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.

VS Description of the processor

The Intel Core i9-11900K is the direct successor to the Intel Core i9-10900K, but the 11th generation of the Intel Core i9 processors now only has a maximum of 8 CPU cores, which is a step backwards to the 10th generation, which is still over 10 CPU cores. The reason is the backporting of the new "Rocket Lake S" architecture, which was actually designed for Intel's 10 nm production. Like all Core i processors of the 11th generation, the Intel Core i9-11900K is now manufactured in 14 nm. One suspects production and delivery problems on the part of Intel. However, by backporting to the 14 nm node, a maximum of 8 CPU cores can be produced economically.

The base clock of the Intel Core i9-11900K is 3.5 GHz, 4.8 GHz are possible on all 8 cores or 5.3 GHz on one CPU core via Turbo. The Intel Core i9-10900K has 10 cores, which it clocks at 3.7 GHz. Here, too, significantly higher clock frequencies are possible in turbo mode: up to 4.9 GHz under load on all cores or 5.3 GHz on one core.

Both processors support Hyper-Threading and can therefore process 16 (Intel Core i9-11900K) or even 20 threads (Intel Core i9-10900K) at the same time. The multiplier is also "free" for both processors, i.e. the processors can easily be overclocked. However, this requires very good air or, better still, water cooling.

In benchmarks, the Intel Core i9-11900K can set itself apart from its predecessor by between 12 and 15 percent under load on just one core thanks to the IPC increase in the new architecture. This is a similarly high increase that AMD was able to achieve with the Ryzen 5xxx series.

In multi-core scenarios, however, the newer Intel Core i9-11900K is about 10 percent behind its predecessor, which is due to the reduced number of cores.
