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.

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 !

VS Description of the processor

Even if it looks like it at first glance, there is only one processor generation between the AMD Ryzen 9 5900X and the AMD Ryzen 9 3900X. The AMD Ryzen 9 5900X was launched in the fourth quarter of 2020, the AMD Ryzen 9 3900X a little more than a year earlier in the third quarter of 2019.

Both processors have 12 physical cores, support hyperthreading and are also overclockable. The difference is in the details, both processors are manufactured in the 7 nanometer process, but the AMD Ryzen 9 5900X is already based on the Zen 3 architecture, whereas the AMD Ryzen 9 3900X is still based on the previous architecture (Zen 2).

The improved architecture allows the processor cores to run faster. With the AMD Ryzen 9 5900X, the base clock frequency of 3.70 gigahertz is slightly lower than that of the AMD Ryzen 9 3900X (3.80 gigahertz), but it can clock higher in turbo mode:

AMD Ryzen 9 5900X = single-core turbo: 4.80 gigahertz / multi-core turbo: 4.50 gigahertz
AMD Ryzen 9 3900X = single-core turbo: 4.60 gigahertz / multi-core turbo: 4.20 gigahertz

Both processors do not have an internal graphics unit, so a dedicated graphics card is required for operation.

There are no differences in the supported memory. Both processors rely on modules of the DDR4 type with a clock frequency of up to 3200 megahertz. The 2 available memory channels are able to work with up to 128 gigabytes of memory and memory with automatic error correction (ECC memory) is supported by both processors.

There is no difference in the L3 cache (64 megabytes each) or in the PCI Express version (4.0) and the number of PCI Express lines (20).

Both processors have a TDP of 105 watts, but in reality the energy consumption ex works is already well over 105 watts.
