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

Temperatures

If you really needed to, you could equip the Ryzen Threadripper 2970WX with a potent air cooler, so long as you don't overclock manually or activate Precision Boost Overdrive. However, a large Blender workload would completely overwhelm it. Conventional heat sinks and fans just aren't up to the task.


Ryzen Threadripper 2970WX can hit 450W during everyday operation. That amount of waste heat requires more than air or a compact all-in-one liquid cooler. You need a much more capable thermal solution if you want to unlock the CPU's maximum performance potential.

AMD deserves credit for this processor's finely-tuned protection mechanisms. Even with PBO active, you can easily push Threadripper 2970WX to the limits of a weaker cooler without damaging it. But you have to give up proper performance in return.

XFR2 and PBO both work well on a platform with ample cooling. The chip adjusts its voltages based on telemetry data, and PBO is actually preferable to manual overclocking. While we're not fans of hidden mechanisms, PBO does exactly what you expect.

AMD prioritizes package temperature: all measurements and information are based solely on this Tdie reading. For compatibility reasons, the 27°C-higher Tctl value is used for fan control. AMD sets the upper limit for Ryzen Threadripper 2970WX at 68°C, which translates to a Tctl value of 95°C.

At idle, our cooler keeps Ryzen Threadripper 2920X below 25°C. Under a real-world Blender workload, we average about 43°C with the CPU keeping all cores at 4 GHz. With PBO active, the 2920X accelerates to 4.15 GHz across all of its cores. The average Tdie rises to just over 49°C. This gives us a maximum delta  of less than 30°C for our potent cooling solution.

During a normal Blender workload without PBO, Ryzen Threadripper 2970WX reaches 3.55 GHz on all cores and averages 48°C. With PBO turned on, the all-core clock rate jumps to 4.025 GHz at an average temperature of 62°C.

The CPU does peak at 68°C though, meaning our sample is at its limit for full performance. Any higher and it would need to throttle back a bit.

    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!

    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.
