AMD Ryzen Threadripper 2970WX Review: 24 Cores on a Budget

Rendering, Encoding and Compression

Rendering

Many of these workloads stress the memory subsystem, diminishing Ryzen Threadripper 2990WX's core count advantage due to accesses from the remote memory controllers. The 2970WX benefits from higher clock rates to surpass the 2990WX in our single-threaded POV-Ray and Cinebench tests. Both are closely matched after we active PBO, though.

If you're looking for single-threaded supremacy, Intel's ninth-gen chips cannot be beaten, as evidenced by Core i9-9900K's dominance.

Threaded workloads are an ideal match to Threadripper's high core counts. But the Ryzen Threadripper 2990WX doesn't scale linearly in these types of workloads. That means the 2970WX's $500-cheaper price is attractive for high-end desktop PCs.

Encoding & Compression

Our compression and decompression metrics work directly from system memory, removing storage throughput from the equation. This workload should benefit from threading. But either memory throughput or poor software scaling holds the 2990WX back from realizing its potential in the compression test. The same issue affects Ryzen Threadripper 2970WX, though Dynamic Local Mode provides a slight performance uptick. But neither the 2970WX nor the 2990WX are a match for the 2920X and 2950X with their dual-die architectures. Conversely, the WX chips dominate our decompression tests, illustrating the performance trade-offs AMD's highest-end CPUs force you to make.

y-cruncher, a single- and multi-threaded program that computes pi using AVX instructions, is a great test to measure Threadripper’s AVX performance. Intel’s Core i9 employs two 256-bit AVX FMA units per core that operate in parallel, whereas Ryzen's Zen architecture divides 256-bit AVX operations across two FMA units per core. Intel's AVX instruction support shines during the single-threaded benchmark. However, spreading the workload across Threadripper's many cores helps improve its standing. Despite an eight-core advantage, the 2990WX offers little benefit over the 2970WX in the threaded y-cruncher test. Clearly, their cores suffer from a memory bandwidth bottleneck.

    Threadripper and Cake or Death!

    I'll have the Threadripper please.
    Very well! Give him Threadripper!

    This would be ideal for me, but it is pricey for now.

    New = Pricey
    Always going to be that way
  • Peter Martin
    yeah. i can wait... lol, still, I need one.

    Basin Falls may be soldered, but considering that the solder in the 9000-series doesn't seem to do as much as people had hoped, we should be prepared for there not to be a lot of OC headroom.

    If you can't afford it, you don't need it. Anyone who can make actual use of this CPU is using it in a business which is generating the money necessary to pay for it.

    Exactly, if I were in a business to generate content I would take the 24 core TR4 CPU over the 18 core Intel equivalent for less money any day of the week. Not everything is made to play games on it.

    who are you to determine my needs?
  • Dorian Kunch
    Why he is the internet IT god, bow to it it it it one one one one
    Give it the Threadripper.
    Give it!
  • mellis
    Looks like the I9-9900K is the best bang for the buck.
  • Peter Martin
    I would be able to make some money with that for sure. fine, now where is that business plan?

    The article states "AMD's XFR (eXtreme Frequency Range)" but it should be "AMD's XFR (Extended Frequency Range)".

    Good eye, fixed!

    get out intel they using this to win share and profit from gamer. Threadripper will be best of both world. what else intel can pull ? no reason to let intel win all the games because they doesnt help competition in the further run. If they win you wont find any cheap cpu in the next 5 years

    something, intel has solved a problem in CPU design amd did not, it is getting it cool enough for long time high frequency. It is why it could run seamlessly for hours... AMD has problem in high frequencies. AMD uses twice amount of resources in smaller cores, Intel is very monolithic package, so, runs the same performance in different workloads..
    Intel has bigger cores, but less sillicon, because it is one thread execution in parallel, so, in very high # of threads (benchmarks only), amd is winner...

    Thanks!

    Intel i9 9900k is impressive reminds me of i7 7700k... in real workloads, this beast beats no matter who is against it......
  • mitch074
    Some benchmarks show that threadripper 2970/2990 work much better under Linux. At one time this website also ran these tests, but not anymore.
  • Lasselundberg
    why or why 1080P gaming results...people buying threadrippers are not gonna sit behind a 1080P monitor....
  • bobba84
    Threadripper is an incorrect name for it, it's crap performance per thread.
  • antonvantov
    Really Winer in theese review is - Rizen 7 2700X.
  • muffindell66
    Threadripper isn't designed for gaming, so why test it for gaming?
