The fastest workstation overall
For unrivaled speeds, professionals should look no further than the Bizon ZX9000 workstation, a monstrous PC that offers enterprise-grade performance for a handful of use cases. These include AI, big data analytics, high-performance computing, business intelligence, and academic research.
Why is the Bizon ZX9000 the fastest? The best configuration includes two of the latest 192-core AMD EPYC 9965 processor, which is by far the fastest CPU on the planet right now. This is partnered with up to 141GB of dedicated graphics in the form of eight NVIDIA H200 GPUs and up to 6TB DDR5 RAM. This comes alongside the option to fit the Bizon ZX9000 with a 61.44TB PCI-E 4.0 NVMe SSD (with additional storage also available).
There’s a host of additional tweaks you can make to the Bizon ZX9000 to really push it to the limits, including packing it with the latest network adaptor, RAID controller, as well as a second SSD to reinforce the first. The most expensive configuration will set you back more than $750,000 – but you can pick it up for little more than $30,000. There’s little beating it, however, for sheer performance
The fastest gaming PC
There’s truly a fine line between the fastest gaming PCs, which is perfectly exemplified by neck-and-neck benchmarking between the MSI Infinite RS 13th and the Alienware Aurora R15, based on testing by our sister site Tom’s Hardware.
Both are fitted with the Intel i9-13900KF and similar GPUs – MSI RTX 4090 Surpim Liquid X and Nvidia GeForce RTX 4090 respectively. But the former just edges it, besting the latter in single-threaded and multi-threaded performance, according to Geekbench 5 testing. This comes alongside wins (or ties) when being put through the paces on a number of high-intensity titles including Borderlands 3, Far Cry 6, Grand Theft Auto V, and Shadow of the Tomb Raider.
Both systems are worth considering and, ultimately, other factors may come into play if you’re deciding to purchase one or the other. Price, for one, is key, while data writing speeds may also play a role; the MSI’s data transfer speeds are significantly slower than the Alienware, and both were beaten by the HP Omen 45L. You may want to look elsewhere for the best gaming PC, depending on your criteria, but there’s little doubt the MSI Infinite RS 13th is number one for speed.
The fastest affordable PC
Available for under $1,000, this high-powered desktop PC offers fantastic value for money. Dell has carved out a reputation for building extremely reliable and high-performing machines, and the XPS line of notebooks and desktops has typified this. Although the XPS machines are on the way out, you can definitely grab one of the fastest workstations for less in the form of the XPS Desktop 8960.
Available at the time of writing for $960, the XPS Desktop 8960 is fitted with a 20-core 14th Gen Intel Core i7 14700 processor and is paired with Intel UHD Graphics. You'll also benefit from 16GB DDR5 RAM and a 1TB SSD. This machine is, in summary, perfect for remote or hybrid workers looking for a new home PC, or for professionals hoping to get more bang for buck than a laptop might offer.
The fastest Mac workstation
Fitted with Apple’s 24-core M2 Ultra CPU, the latest high-performance custom-built processor, is the Apple Mac Studio. It’s unbeatable for performance across Apple’s range of macOS devices, including iMac and MacBook Pro devices as well as Mac Studios powered by the M2 Max CPU.
Professional creatives, in particular, will be salivating at the prospect of the performance gains against Apple’s previous generation of processors. The M2 Ultra-fitted Mac Studio, which boasts up to 76GB GPU and up to 192GB unified memory, performs transcoding tasks, video exports, 3D rendering, or complex simulations several times faster than previous Apple chips, for example.
The Mac Studio is also paired with 64GB unified memory, configurable to up to 192GB, alongside a maximum 8TB SSD. With the M2 Ultra, the Mac Studio can support up to three 8K displays at 60Hz, and has a variety of ports including HDMI, USB-A and Thunderbolt 4, alongside an SDXC card slot. This comes alongside Bluetooth 5.3 and Wi-Fi 6E.11.
