Conclusion: History is Written By The Victors

I have never used the word ‘bloodbath’ in a review before. It seems messy, violent, and a little bit gruesome. But when we look at the results from the new AMD Threadripper processors, it seems more than appropriate.

When collating the data together from our testing, I found it amusing that when we start comparing the high-end desktop processors, any part that was mightily impressive in the consumer space suddenly sits somewhere in the middle or back, holding its lunch money tightly. While the 16-core Ryzen 9 3950X and the 8-core Intel i9-9900KS enjoy a lot fun in the consumer space, when Threadripper rolls up, they are decidedly outclassed in performance.

AMD has scored wins across almost all of our benchmark suite. In anything embarrassingly parallel it rules the roost by a large margin (except for our one AVX-512 benchmark). Single threaded performance trails the high-frequency mainstream parts, but it is still very close. Even in memory sensitive workloads, an issue for the previous generation Threadripper parts, the new chiplet design has pushed performance to the next level. These new Threadripper processors win on core count, on high IPC, on high frequency, and on fast memory.

Is the HEDT Market Price Sensitive?

There are two areas where AMD will be questioned upon. First is the power, and why 280 W for the TDP? Truth be told, these are some of the most efficient desktop cores we have seen; it's just that AMD has piled a lot of them into a single processor. The other question is price.

Where Intel has retreated from the $2000 market, pushing its 18-core CPU back to $979, AMD has leapfrogged into that $1999 space with the 32-core and $1399 with the 24-core. This is the sort of price competition we have desperately needed in this space, although I have seen some commentary that AMD’s pricing is too high. The same criticism was leveled at Intel for the past couple of generations as well.

Now the HEDT market is a tricky one to judge. As one might expect, overall sales numbers aren’t on the level of the standard consumer volumes. Still, Intel has reported that the workstation market has a potential $10B a year addressable market, so it is still worth pursuing. While I have no direct quotes or data, I remember being told for several generations that Intel’s best-selling HEDT processors were always the highest core count, highest performance parts that money could buy. These users wanted off-the-shelf hardware, and were willing to pay for it – they just weren’t willing to pay for enterprise features. I was told that this didn’t necessarily follow when Intel pushed for 10 cores to $1979, when 8 cores were $999, but when $1979 became 18 cores, a segment of the market pushed for it. Now that we can get better performance at $1999 with 32 cores, assuming AMD can keep stock of the hardware, it stands to reason that this market will pick up interest again.

There is the issue of the new chipset, and TRX40 motherboards. Ultimately it is a slight negative that AMD has had to change chipsets and there’s no backwards compatibility. For that restriction though, we see an effective quadrupling of CPU-to-chipset bandwidth, and we’re going to see a wide range of motherboards with different controllers and support. There seems to be a good variation, even in the initial 12 motherboards coming to the market, with the potential for some of these companies to offer something off-the-wall and different. Motherboard pricing is likely to be high, with the most expensive initial motherboard, the GIGABYTE TRX40 Aorus Extreme, to be $849. Filling it up with memory afterwards won’t be cheap, either. But this does give a wide range of variation.

One of the key messages I’ve been saying this year is that AMD wants to attack the workstation market en mass. These new Threadripper processors do just that.

The Final Word

If you had told me three years ago that AMD were going to be ruling the roost in the HEDT market with high-performance 32-core processors on a leading-edge manufacturing node, I would have told you to lay off the heavy stuff. But here we are, and AMD isn’t done yet, teasing a 64-core version for next year. This is a crazy time we live in, and I’m glad to be a part of it.

AMD Third Generation Ryzen Threadripper

Price no object, the new Threadripper processors are breathing new life into the high-end desktop market. AMD is going to have to work hard to top this one. Intel is going to have to have a shift its design strategy to compete.

Many thanks to Gavin Bonshor for running the benchmarks, and Andrei Frumusanu for the memory analysis.

    Too expensive. Anything over $300 for a cpu is a ripoff. See you in two years when these threadrippers are obsolete. Reply

    Very likely it is a new plateau enabled by 7nm and brand new Zen architecture developed to its potential. I predict small improvements from here for the next several years as it has been with Intel since Sandy Bridge - only better AVX512 implementation on something like 5nm and DDR5 will bring some improvements, but don't expect wonders on most tasks which don't care about memory throughput or AVX512.

    The upcoming Zen 3 architecture revision is reported to provide up to a ~10% IPC uplift, with some neat tricks such as unifying the L3 cache per chiplet (no more CCX contention).

    There's always something better around the corner. :)

    Nope, it's the CCX size that changes from 4 to 8 cores. Reply

    "Up to 10%" - exactly what I have meant, a plateau, like Intel had after Sandy Bridge, adding only ~5% each year... Reply

    peevee um intel could of improved their ipc more each year.. but they didnt, there was no reason too.. just like they could of given mainstream more then 4 cores.. but they didnt as well.. mostly because of zen.. is there more then 4 cores from intel.. Reply

    It's too bad they aren't available anywhere other then a few system builders. ie CyberPower , Origin , and others.

    Some of us who would use one of these new processors dont want to pay the extra 1500-2k for someone else to build it when we could do it ourselves.

    AMD was really short sighted not at least having some supply at Newegg, Microcenter, Fry's, etc.. on launch day.

    That's a lot of power needed for 24 cores. 3960 at 280w. And it's recommended to get water cooling? They aren't going to get many buyers on that.
    6 more cores than Intel 10980, but needs 90w more power to get there.
    I thought 7nm would be better than this.
    The Xeon is way out of wack at 381.

    People that really need the speed to save in man hour costs, expect a high end system with warranty, instant replacement, compatibility (especially vm), and reliability. I don't think you are going to get that with water cooling. And I don't see any major players that offer what I listed, going to a water cooled system anytime soon.

    pricey though but its liquid cooled

    Not exactly mainstream. I'm talking Dell, HP Reply
