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.

Intel Core i9-12900K AMD Ryzen 9 5950X
Unknown Unknown
The two processors from this comparison belong to the highest class of consumer processors. The Intel Core i9-12900K came on the market in the fourth quarter of 2021 and is based on the Alder Lake S architecture. This CPU is still manufactured using the 10 nanometer process and belongs to the 12 generation of Intel's I processor series. The AMD Ryzen 9 5950X came onto the market in the fourth quarter of 2020, but was already manufactured there using the 7 nanometer process. The AMD processor is based on the Zen 3 architecture with the code name Vermeer and, like the Intel Core i9-12900K, is designed as a desktop processor.

The Intel Core i9-12900K has a total of 16 cores, which are divided into 8 high-performance cores (Golden Cove) with hyperthreading and 8 energy-saving cores (Gracemount) without hyperthreading. The base clock frequency is 3.20 gigahertz and the maximum turbo clock is 5.20 gigahertz. The AMD Ryzen 9 5950X also has 16 cores, but they are all equally potent and support hyperthreading technology. The standard clock is 3.40 gigahertz and the maximum turbo clock is 4.90 gigahertz.

In our benchmarks, the Intel Core i9-12900K scores around 10-15% better with single core load. Due to the 16 equally strong cores, the AMD Ryzen 9 5950X clearly catches up in the multicore benchmarks and is only slightly behind the Intel Core i9-12900K here.

The internal graphics unit Intel UHD Graphics 770 is built into the Intel Core i9-12900K, which clocks at up to 1.45 gigahertz and is equipped with 32 execution units and 256 shader units. This iGPU achieves an FP32 processing power (single precision) of 742 gigaflops. With the AMD Ryzen 9 5950X you have to do without an internal graphics unit and instead use a dedicated graphics card.

Both processors support DDR4-3200 RAM and the Intel processor also supports DDR5-4800 memory modules.
