Intel lately introduced its lineup of Sapphire Rapids Xeon CPUs for workstations. They’re nonetheless a month or two away, however within the lead-up to the on-sale date, Intel invited German overclocker de8auer to its labs for a fast overclocking take a look at. That some Sapphire Rapids workstation CPUs are overclockable is each a primary for Intel and an enormous promoting level. To exhibit the probabilities, de8auer and an Intel worker confirmed some spectacular preliminary outcomes, regardless of it being on pre-release {hardware}. Nevertheless, the efficiency comes at the price of severe energy consumption.

The chip being examined right here is the flagship W9-3495X, which has 56 cores and 112 threads. The motherboard is an Intel validation board, so it’s pretty pedestrian so far as VRM cooling goes. The CPU is cooled by a 360mm AIO made by Cooler Grasp. There’s 192GB of DDR5 working at 5,600MHz throughout eight channels. Because the host notes, a system like this may most likely begin at round $10,000.

Within the video, the Intel worker runs Geekbench 5 Professional however CPU-Z is open to watch clock speeds. For the take a look at, all 56 cores have been working at 4.2GHz. For context, this CPU has a most single-core turbo frequency of 4.6GHz and a Turbo Increase 3.0 frequency of 4.8GHz. In different phrases, it is a modest all-core overclock.

Regardless of the above actuality, it was nonetheless in a position to smash the world file in Geekbench. The title was beforehand held by a 64-core AMD Threadripper Professional CPU that scored 48,025 factors. The Sapphire Rapids CPU crushed that to the tune of a 53,817 multi-core rating. That’s a 12% delta, spectacular because the Intel CPU has fewer cores and was additionally working at decrease clocks: 4.2GHz versus 4.3GHz on the Threadripper.

Whereas the chip was busy setting a brand new world file in Geekbench, it appears to have additionally set a brand new file for energy consumption. Energy draw was measured on the wall with a Watts Up? meter, and it confirmed it hitting 1,097W briefly. When working the single-threaded portion of the benchmark, it hovered round 375W earlier than spiking as much as round 700W, then 800W, and so forth. After going over 1,000W, it settled again all the way down to round 650W. de8auer famous that with higher cooling, it might have most likely overclocked to round 4.6GHz.

If you happen to’re not into overclocking, Cinebench was additionally run in “inventory” trim on an Asus workstation board. One fascinating spotlight of the visible walkaround is the Asus board gives twin 24-pin energy connectors in case you need to run two PSUs. Total the system hit round 70,000 in Cinebench with solely XMP enabled on the reminiscence. The W9-3495X CPU was working all cores at 2.9GHz. For comparability, our colleagues at PCMag obtained 39,022 out of a Core i9-13900K in its overview.

One last notice; proper as we went to press, we seen somebody has certainly already utilized unique cooling to this CPU. In response to a new submission to the HWBOT chief boards for Cinebench, a W9-3495X now holds the highest spot. A person named Safedisk utilized some LN2 cooling to the chip, permitting it to hit 5.2GHz on all cores. That enabled a mind-bending rating of over 128,000 on Cinebench.
