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

Power Consumption

Interestingly, AMD reduced the idle power consumption of its second-gen Threadripper CPUs a bit. This is certainly motherboard-dependent, so be sure you're using the latest BIOS on your X399-based motherboard.

Just be ready for Windows 10 to bounce you back to 25-40W as background processes kick on and off (and particularly with PBO enabled for additional performance).

Ryzen Threadripper 2920X with PBO enabled hits clock rates as high as 4.3 GHz in our CAD workload, so power consumption spikes as well. The 2970WX is similar in that its high boost frequency results in a >64W measurement.

Our Witcher 3 benchmark is great for GPU power consumption comparisons. But it's less enlightening when we run it across different host processors because the underlying engine doesn't use enough cores. Assassin's Creed Odyssey is better about utilization, causing Threadripper's power to spike in excess of 100W. But that game's averages are far from reproducible, forcing us to keep it on the shelf.

Prime95 certainly isn't representative of an everyday scenario, but it's great for measuring peak theoretical power consumption. Some real-world applications pull even more power. For instance, a real Blender workload drives the 2970WX up to 230W, while we only measured 210W with Prime95! The same applies when we switch on PBO: Blender coaxes 447W from the Ryzen Threadripper chip compared to 416W in Prime95.

The smaller Ryzen TR 2920X is slightly different. It pulls 160W during the Blender workload, whereas Prime95 shows a power consumption of 180W. Activating PBO increases the delta: we measure 200W during the Blender test and 249W in Prime95. We can't explain why both CPUs react differently, but their results are reproducible.

    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!

    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!
  • mustafa.technet
    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?
  • carl_heinz
    Why everyone is praising the new threadripper with its lousy performance?!!! I need to check the graphs again and read the conclusion to see what I really missed!!!
  • Olle P
    Some observations:
    * In the last set of graphs the "Compression" and "Decompression" graphs are mixed up and should be the other way around. (Ryzen is much better at decompression than it is at compression.)
    * It's a pity that the Core i9-7920X isn't in there. That's the only relevant Intel offering at this price point.
    * While the 2970WX can draw >400W when overclocked, it's marginally less power hungry than i9-7900X at stock settings.

    Not for any of the work the TR is intended for.

    in a multitasking multicore world, the last think i would expect a reviewer to put in a review is anything dealing with "single core" performance.

    Multitasking means you are running multiple tasks,some of those might be single core tasks.
