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 comparison between the Intel Core i9-12900KF and the Intel Core i9-12900K is actually quick, but I still managed to write a few words about the technical details of these CPUs.

The two processors came onto the market at the end of 2021 and are based on Intel's Alder Lake S architecture. With this architecture, Intel has managed to have the fastest mainstream processor on the market again, after the biggest competitor AMD has set the tone with its Ryzen processor for the past few years.

For the first time, Intel is using a big.LITTLE architecture, with 8 of the 16 built-in cores being high-performance cores and the remaining 8 being energy-saving cores. The clock rates are identical at 3.20 gigahertz (standard clock) and 5.20 gigahertz (turbo clock). Hyperthreading technology is only supported by the high-performance cores, which means that the processors have up to 24 threads at their disposal.

The only difference between the two processors is that the Intel Core i9-12900KF does not have an internal graphics unit, but the Intel Core i9-12900K uses the Intel UHD Graphics 770. This iGPU has 32 execution and 256 shader units and clocks at up to 1.55 gigahertz. The 11th generation Intel iGPU has an FP32 computing power (single precision) of 794 GigaFLOPS.

DDR4-3200 and DDR5-4800 modules are supported for RAM. Slower RAM modules can also be installed, faster modules can work but are not officially supported. The processors have 2 memory channels with which up to 128 gigabytes of RAM can be operated. ECC memory is not supported.

The processors each have 20 type 5.0 PCIe lines, which can be used to connect compatible expansion cards.
