Possible AMD Threadripper 3000-Series Castle Peak 16-Core CPU Appears

Hardware leaker TUM_APISAK has unearthed a UserBenchmark result of an unidentified AMD 16-core processor. Judging by its specifications, the chip appears to be one of AMD's upcoming Threadripper 3000-series processors (codenamed Castle Peak).

In a recent sitdown with AMD President and CEO Dr. Lisa Su, she reiterated the company's commitment to the HEDT market and implicitly hinted that the chipmaker is preparing its third-generation Threadripper chips. Su didn't reveal a concrete launch date for the new multi-core monsters. However, if AMD follows recent norms, it could release them next month. Looking back at Threadripper's history, we can recognize a fairly consistent pattern. AMD launched the first-and second-generation Threadripper processors in August 2017 and 2018, respectively. There's a good chance AMD could continue that trend.

Ryzen Threadripper 3000-series processors will use AMD's latest Zen 2 processor microarchitecture, so they will probably come out of TSMC's 7nm FinFET stove and support the PCIe 4.0 interface. The new parts will likely work on existing X399-based motherboards through a BIOS update. However, AMD might introduce a new chipset to take advantage of the PCIe 4.0 functionality.

The leaked AMD 100-000000011-12 sample has the OPN (Ordering Part Number) in the codename, which implies the specifications are very close to what we can expect from the final product. UserBenchmark detects the processor with 16 cores, 32 threads, 3.6 GHz base clock and 4.05 GHz average boost clock. The benchmark identifies the system as AMD Sharkstooth and recognizes the motherboard with an SP3r2 (TR4) socket with quad-channel memory support.

Although UserBenchmark isn't our preferred benchmark tool, some valuable data proves useful. The unknown part is seemingly up to 11% faster than the current Threadripper 2950X in single-core and quad-core tests. When it comes to multi-core workloads, the chip performs up to 18% faster than second-gen Threadripper.

On the other hand, the AMD 100-000000011-12's performance is on par with the Ryzen 9 3900X when it comes to single-core and quad-core workloads. As expected, the Threadripper sample beats the Ryzen 9 3900X by up to 35% in multi-core workloads.

The Threadripper 3000-series lineup will be an exciting lineup for sure. We can't wait to see what AMD has up its sleeves.

    Just pointing out, the 3950x is not $399, its $749.

    This looks very unlikely.
    Given that TR can have 80-100% higher TDP compared to desktop, there is no way it should be at 700MHz lower clock than equivalent desktop CPU.

    They would have to use total trash chiplets to clock lower than 1st generation zen cores.

    The average turbo reported in userbenchmark is going to be significantly lower than the max rated boost clock. E.g. for the 3900X it's typically around 4-4.1 GHz, in contrast to the rated 4.6 GHz max boost. Given that the 3950X has 33% more cores but the same TDP as the 3900X, I'd expect the heavily threaded boost clocks to be lower than that. So the 16C TR could still end up having higher real world boost clocks than the 3950X even if these results are more or less valid.
