AMD Ryzen Threadripper PRO 7985WX 64-core sTR5

The Threadripper PRO 7985WX posts a 131,837 PassMark multi-thread score, putting it in the 99th percentile of our database. It's a 64-core, 128-thread beast with 8-channel DDR5 and 256MB of L3 cache. But it draws 350W, has no integrated graphics, and needs a serious cooling solution.

Let's talk numbers, because this chip has plenty of them. The 131,837 PassMark multi-thread score is top of the charts, 99th percentile in our database. That's not just fast, it's the kind of score that makes you double-check the benchmark finished. The 64 cores and 128 threads on the 5nm TSMC process chew through parallel workloads like they're nothing. Single-thread performance holds up too at 3,960, which is a standout result for a chip this wide.

The 8-channel DDR5 memory support is a big deal for bandwidth-hungry workloads. With up to 2TB of ECC memory supported, you can load entire datasets into RAM and let the 256MB of L3 cache do its thing. PCIe 5.0 support means you're not bottlenecking storage or GPU throughput either. The 350W TDP is the price of admission here, and the efficiency score of 41.2/100 in our database reflects that. This chip is a sprinter, not a marathon runner, and it drinks power accordingly.

Against the Intel Core Ultra 9 285K, the Threadripper PRO 7985WX is in a completely different weight class. The 285K is a consumer desktop chip, while this is a workstation processor with 64 cores to the 285K's 24. The multi-thread gap is enormous, with the 7985WX's 131,837 PassMark score dwarfing what the 285K can manage. But the 285K has integrated graphics and a much lower TDP, so it's a better fit for general desktop use. The other competitors in our database, like the Xeon P67080-B21 and the Core i9 X-Series chips, are older architectures that can't match the Zen 4 core count or the DDR5 memory bandwidth. If you need maximum parallel throughput, the 7985WX is the clear winner. If you need a balanced desktop chip, look elsewhere.

Pricing on this chip is all over the map. In USD, we're seeing listings from $999 to $16,550 across 4 vendors, which is a spread of $15,551. That's not a typo. The $999 listing is either a pricing error, a scam, or someone clearing inventory at a loss, because the EUR listings tell a more consistent story at €6,515 to €9,557. CAD listings sit between CA$10,800 and CA$11,400. If you're shopping in USD, that $999 price is tempting but I'd verify the seller's legitimacy before clicking buy. For everyone else, this is a workstation investment, not a casual upgrade, and the price reflects that.

The AMD Ryzen Threadripper PRO 7985WX is a 64-core, 128-thread monster that sits in the 99th percentile for multi-thread performance in our database. With a PassMark multi-thread score of 131,837, it's the kind of chip that makes render farms nervous and workstation users very happy. The 5.1GHz boost clock on Zen 4 architecture means you're not sacrificing single-thread speed either, landing at 3,960 on PassMark single-thread, which puts it in the 91st percentile there.

But here's the thing: this is a 350W TDP processor with no integrated graphics and no cooler in the box. You're building a serious system around this chip, not just dropping it into an existing rig. The 256MB of L3 cache and 8-channel DDR5 support with ECC up to 2048GB tells you exactly who this is for: people running simulations, rendering pipelines, AI workloads, and other tasks that eat cores for breakfast.

If you're building a gaming PC or a general-purpose desktop, skip this chip. The 350W TDP means you'll need a serious cooling solution, and the lack of integrated graphics means a discrete GPU is mandatory. The efficiency score of 41.2/100 in our database is a real weak spot, and the customer rating of 2.6/5 from 6 reviews suggests some buyers have run into issues. The 5th percentile social proof score means there's very little real-world feedback to lean on. If your workload doesn't scale across 64 cores, you're paying a premium for performance you'll never tap into.

The Threadripper PRO 7985WX is a specialized tool for specialized workloads. The 99th percentile multi-thread performance and 8-channel DDR5 support make it a top pick for rendering, simulation, and AI workstations. But the 350W TDP, lack of integrated graphics, and missing cooler mean you're committing to a full system build with serious cooling. The 2.6/5 customer rating from 6 reviews is concerning, though with such a small sample size it's hard to draw firm conclusions. If your workload scales across dozens of cores and you have the budget for the supporting hardware, this chip delivers. If you're building a general-purpose PC, you're paying for performance you'll never use.
