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.

Unknown Unknown

The two processors from this comparison were released in the second quarter of 2020 and come from the tenth generation of Intel's Core i processors. They are therefore based on the Comet Lake architecture, which is manufactured using the 14 nanometer process.

The Intel Core i3-10100 has 4 processor cores. These have a basic clock rate of 3.60 gigahertz and a maximum turbo clock rate of 4.30 gigahertz. The Intel Core i5-10400 has, with 6 processor cores, 2 cores more than the comparison processor. The basic clock frequency of these 6 cores is significantly lower at 2.90 gigahertz, but the maximum frequency in turbo mode is the same at 4.30 gigahertz. Both processors support Hyper-Threading technology, so the additional cores of the Core i5 processor make the difference in the benchmarks.

The single-core benchmarks also show us that the two processors perform on par here. As already mentioned, the Intel Core i3-10100 can no longer keep up in the multi-core benchmarks. The 2 additional cores of the Intel Core i5-10400 give it a performance advantage of 25-30 percent.

The two processors are equipped with the same internal graphics unit. The Intel UHD Graphics 630 is used in each case. This iGPU has 24 execution units with 192 shader units and, like the processors, is manufactured using the 14 nanometer process. But there is a small difference, because in the Intel Core i3-10100 the graphics unit clocks with a maximum of 1.10 gigahertz, in the Intel Core i5-10400 the maximum clock is slightly higher at 1.20 gigahertz. Due to this difference, the graphics unit in the Intel Core i3-10100 achieves an FP32 processing power of 422 GigaFLOPS, whereas the same iGPU in the Intel Core i5-10400 achieves an FP32 processing power of 461 GigaFLOPS.

Both processors support the operation of up to 128 gigabytes of RAM of the DDR4-2933 type.
