AMD’s Ryzen Threadripper 1950X CPU gets chilly, blows through 5GHz ceiling

During AMD’s Capsaicin SIGGRAPH 2017 event celebrating the launch of its Ryzen Threadripper and Radeon RX Vega products in August, the company hosted a special overclocking session to push the limits of the upcoming Ryzen Threadripper 1950X processor. The overclocking team used liquid nitrogen (LN2) in a controlled environment, so don’t expect to reach their speed using simple tweaks at home.

Out of the box, this chip has a base clock speed of 3.4GHz, a boost speed of 4.0GHz, and a maximum speed of 4.2GHz via the Extended Frequency Range (XFR) feature used in AMD’s new “Zen” processor design. But the liquid-cooled chip went beyond that XFR clock speed using all 16 cores. This was accomplished by slowing down the PCI Express lanes and feeding the chip extra voltage while slowly cranking up the speed of all physical cores.

In the first stage of the overclocking event, Lab501 reached 4.8GHz and loaded up the popular Cinebench performance measuring software to achieve a score of 3,688. The team then increased the overclocked speed to 5.2GHz and saw a score of 4,122 in Cinebench. Prior to the event, the highest score achieved by a 16-core processor in Cinebench was 2,867.

The 1950X processor is one of three Ryzen Threadripper chips officially announced by AMD on Sunday. Three more are expected to arrive in the future without the “X” branding: the 16-core 1950, the 12-core 1920, and the 8-core 1900. The base and boost speeds are unknown for now, but they will likely have the same 180-watt power draw as the three current chips.

As we noted last week, the big duel between AMD and Intel will be with their 16-core, 12-core, and 8-core models. And now that AMD has officially announced its Ryzen Threadripper 1900X, we can better compare AMD against Intel’s Core i7-7820X in a performance-per-dollar ratio.

AMD’s low-tier Threadripper chip still won’t hit the same maximum speed as Intel’s solution, but it has a faster base speed and costs slightly less. The chip’s shortcoming regarding its maximum speed could theoretically be ratified by overclocking the chip, but not at the speeds seen during AMD’s special event during SIGGRAPH 2017.

News of the Threadripper overclocking limits arrives after Der8auer delidded the 16-core 1950X model to discover that Threadripper chips are rebranded Zen-based Epyc server processors AMD recently launched for the data center market. What components AMD activated and deactivated in the Epyc design for the enthusiast desktop market is unknown.

AMD Ryzen Threadripper 3 vs. Intel Cascade Lake X
Only one high-end desktop processor can be the most powerful CPU for your PC
AMD Ryzen Threadripper 1920X 1950X Review

AMD is assaulting Intel's CPU market on all fronts in 2019. Its Ryzen 3000 mainstream processors provide serious competition across the board for Intel's 9th-generation chips, and as we edge towards the close of the year, the high-end desktop (HEDT) wars have begun anew. AMD has launched its 3rd-generation Threadripper CPUs, while Intel has a new range of Cascade Lake-X chips to counter it.

But which will come out on top? In the Cascade Lake X vs. Threadripper 3000 battle for the best HEDT processors ever, which will take the top spot?

AMD’s insane 64-core Ryzen Threadripper 3990X processor to arrive in 2020
amd debuts third gen ryzen threadripper motherboard closeup

AMD confirmed on Monday that a third new Ryzen Threadripper chip will hit the market in 2020, the 3990X. It will arrive after AMD’s latest Ryzen Threadripper high-end desktop (HEDT) chips for enthusiasts – the 3970X and the 3960X – that's now available to purchase.

AMD said on Monday the 3990X will pack 64 cores, 128 threads, a 288MB total cache, and a thermal design power (TDP) of 280 watts. Unfortunately, the company didn’t provide additional details like frequencies but promised more information would come next year.

MSI leak reveals 64-core AMD Threadripper CPU is just around the corner
AMD Threadripper processor in a motherboard.

MSI may have leaked AMD's still-unannounced 64-core Threadripper 3990X CPU in a recent video showcasing motherboards for the new-generation Threadripper CPUs. Although ostensibly designed with the 32-core 3970X in mind, the system clearly had a 64-core chip installed in the video, which accidentally leaked that information to the viewing audience. It showed a full 64 cores and 128 threads running, no doubt spoiling AMD's planned 2020 unveiling.

As much as this is a misstep by MSI -- since corrected with a new upload of the same video -- AMD has long been rumored to be working on a 64-core version of its Threadripper CPUs. It previously unveiled a 64-core version of its Epyc server chip, which Threadripper is effectively a cutdown version of. It makes total sense that a 64-core version, likely named the Threadripper 3990X or WX, was in the works. But we now effectively have confirmation that it's working.
