Similar to other software developers, Redshift keeps track of the minimum hardware specifications, which you can utilize to make sure your system's hardware satisfies. But this simply addresses the minimum amount of hardware required to run the software; it does not address what hardware will perform at its peak. We've taken the time to research the best hardware for Unity in order to compile our own list of suggested hardware because this list is so basic.

The majority of GPU-based engines, including Redshift, do not directly involve the CPU in the scene rendering process. In the overall scheme of things, its influence on the loading duration of a scene is rather insignificant. To guarantee optimal performance with apps like Cinema4D, Maya, or 3Ds Max, you should use a CPU with a high clock speed if you also want to use the same machine for modeling or animation. However, if you additionally utilize CPU-based rendering engines, then those applications would benefit from having more cores. However, it won't speed up Redshift's rendering.

In addition to pure performance, a CPU's support for PCI-Express lanes should be taken into account. This will control the maximum number of video cards that can be used, which is significant because Redshift render speed is mostly driven by video cards.

• AMD Ryzen 7 7700X 8 Core: This CPU, which has one of the fastest clock speeds on the market, performs excellently in modeling and animation programs as well as Redshift. It supports twin video cards in addition to other common hardware devices (NVMe drives, etc.) with a sufficient amount of PCI-Express lanes.
• AMD Threadripper PRO 7965WX 24 Core: Compared to more consumer-focused variants, AMD's Threadripper PRO processors provide much more PCI-Express lanes. This CPU can support up to four video cards in a single tower workstation when paired with the appropriate motherboard. The ability to fit three or four high-end GPUs in a single system comes at the cost of increased platform costs; however, this benefit is offset in many applications.

We generally recommend a minimum of 32GB of RAM for Redshift (and GPU rendering in general), while exactly how much you require may depend on your specific tasks. Though our systems do offer more for individuals who require it, that ought to be more than plenty for dedicated rendering boxes. You may need 64GB or even more if you frequently have multiple programs open and operating at once, such as Maya, Cinema 4D, After Effects, etc.

Render capabilities are influenced by two factors of a video card: the card's memory capacity and the GPU's actual speed. Large and complicated scenes may not be rendered as well using video memory, although Redshift does offer "out of core" rendering, which permits the usage of system memory in the event that there is insufficient dedicated GPU memory. However, doing so reduces speed, so if at all feasible, use video cards with enough RAM built-in. While Quadro cards have more VRAM and cost more for the same level of raw performance, GeForce cards often have high raw performance and acceptable amounts of visual memory.

• GeForce RTX 4080 16GB: This graphics card is a fantastic option if you only need one or two and don't work with extremely complicated situations.
• GeForce RTX 4090 24GB: With an incredible 24GB of VRAM, the RTX 4090 offers the highest performance in Redshift and is our top choice for the majority of GPU rendering customers.
• NVIDIA RTX 6000 Ada 48GB: NVIDIA's professional GPUs are a good choice for people who want a lot of GPU memory and/or wish to stack multiple video cards in the same system.

Primary Drive: OS/Software (SSD/NVMe): Includes your operating system and the base Redshift installation. An SSD is highly recommended as it will greatly improve how fast the OS and programs startup, but you can also upgrade to a faster NVMe drive for a small performance benefit. The recommended storage for installation of software is not more than 10 GB.

Since the primary drive will primarily be used to store Windows and software, including all software (except large games), it doesn't need to be that large for the majority of users; a 500GB SSD will be enough for Drive C. 

Secondary Drive: Project Files (Platter/SSD/NVMe) Having a second storage (either SSD or HHD) for storing assets and effects is a wonderful alternative if you have additional money to spend or keep a lot of them around for use on different projects. Of course, an internal or external hard drive is a more cost-effective option than a high-capacity SSD if you need more mass storage and preservation.
