The AMD Threadripper 2990WX 32-Core and 2950X 16-Core Review

Test Setup and Comparison Points

In our review kit from AMD, we were supplied with almost complete systems for testing. Inside the box of goods, AMD included:

• AMD Threadripper 2990WX (32C, 250W, $1799)
• AMD Threadripper 2950X (16C, 180W, $899)
• ASUS ROG Zenith Extreme motherboard, rev 2
• MSI X399 MEG Creation motherboard
• 4x8 GB of G.Skill FlareX DDR4-3200 14-14-14
• Wraith Ripper Cooler, co-developed with Cooler Master
• Enermax Liqtech 240 TR4 Liquid Cooler, rated to 500W

For our usual testing, we stick to the same power supplies, the same storage, ideally the same motherboard within a range of processors, and always use the latest BIOS. Despite AMD shipping us some reasonably fast memory, our standard policy is to test these systems at the maximum supported frequency as promoted by the processor manufacturer, or in this case DDR4-2933 for the new Threadripper 2000-series processors.

For our testing we compared the first generation Threadripper processors with the second generation parts. We also have the Intel 18-core Core i9-7980XE, some results from the Core i7-7900X (10-core), and also two mainstream processors, one Intel and one AMD. This is due to our new CPU testing suite, which takes effect today.

Due to an industry event occuring in the middle of our testing, we had to split some of the testing up and take 30 kg of kit half-way around the world to test in a hotel room during Flash Memory Summit. On the downside, it means there is some discontinuity in our testing, although not that much - on the plus side, the hardware tested in the hotel room had a good amount of air-conditioning to keep cool.

The memory for our test suites was mostly G.Skill, with some Crucial. For the EPYC system, Micron sent us some LRDIMMs, so we fired up 1TB of memory to get all eight channels working.

On the Intel side, we are still getting up to speed on our testing.

Over time we will be adding to our Intel CPUs tested.

Many thanks to...

We must thank the following companies for kindly providing hardware for our multiple test beds. Some of this hardware is not in this test bed specifically, but is used in other testing.

Thank you to Crucial for providing us with MX200 SSDs and to Micron for LRDIMMs. Crucial stepped up to the plate as our benchmark list grows larger with newer benchmarks and titles, and the 1TB MX200 units are strong performers. Based on Marvell's 88SS9189 controller and using Micron's 16nm 128Gbit MLC flash, these are 7mm high, 2.5-inch drives rated for 100K random read IOPs and 555/500 MB/s sequential read and write speeds. The 1TB models we are using here support TCG Opal 2.0 and IEEE-1667 (eDrive) encryption and have a 320TB rated endurance with a three-year warranty.

Thank you to Corsair for providing us with an AX1200i PSU. The AX1200i was the first power supply to offer digital control and management via Corsair's Link system, but under the hood it commands a 1200W rating at 50C with 80 PLUS Platinum certification. This allows for a minimum 89-92% efficiency at 115V and 90-94% at 230V. The AX1200i is completely modular, running the larger 200mm design, with a dual ball bearing 140mm fan to assist high-performance use. The AX1200i is designed to be a workhorse, with up to 8 PCIe connectors for suitable four-way GPU setups. The AX1200i also comes with a Zero RPM mode for the fan, which due to the design allows the fan to be switched off when the power supply is under 30% load.

Thank you to G.Skill for providing us with memory. G.Skill has been a long-time supporter of AnandTech over the years, for testing beyond our CPU and motherboard memory reviews. We've reported on their high capacity and high-frequency kits, and every year at Computex G.Skill holds a world overclocking tournament with liquid nitrogen right on the show floor.
