The AMD Ryzen Threadripper 3960X and 3970X Review: 24 and 32 Cores on 7nm
by Dr. Ian Cutress, Andrei Frumusanu & Gavin Bonshor on November 25, 2019 9:05 AM ESTConclusion: 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.

Not.Congrats to AMD on great processors, but the consumer market for $1,4-$2k processors is super tiny.
Despite the current generation of AMD processors for desktops being arguably superior to those of Intel, in the financials, Intel still destroys AMD and it is indeed a bloodbath.
In my opinion, AMD would hurt Intel much more, and in the end earn more money, if it priced its offerings lower, for consumer processors as well as datacenter processors.

Not that small.>> Workstations are a growing market segment and have been for quite some time. They run 24-7, are extremely reliable, and have features and specifications you can’t find in a PC. Therefore, workstations can command high price points because of the high expectations users have for them. Our research shows the market size for workstations is approximately 5.3 million units, about 2% of the total PC market, and brings in over $10 billion dollars a year, almost 2.5% of the PC market total, which indicates the average selling price (ASP) is higher than the ASP of a PC.

Very small. The more cores, the smaller the market. What are so many cores good for? Video editing, huge databases. Financial transactions, which the chips are not likely to be used for.For most everyone else, 8 cores is still the sweet spot.

The review literally discusses this point:"...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.

They need to partner with a workstation vendor such as Dell, HP, etc. - or pick/create a company to partner with. Big businesses like to have a reliable single vendor they can deal with for all their server and workstation hardware, including support.eek2121 - Monday, November 25, 2019 - link
They really need Dell.xrror - Tuesday, November 26, 2019 - link
Sadly Dell always seems anti-AMD - or I guess more accurately they absolutely will not do anything that could jeopardize receiving Intel's contrarevenue.eek2121 - Monday, November 25, 2019 - link
Pretty much anybody that does graphics, video, etc. has a need for these CPUs. A large portion of professional Youtubers use blender or similar applications (that scale perfectly) to render things like 3d animations and the like. On the contrary. The market for these types of CPUs is larger than the gaming market. AMD's biggest obstacle here is getting prebuilt OEM systems built with sufficient cooling. Not many folks in that audience are going to build their own PC.melgross - Monday, November 25, 2019 - link
Nope. Graphics apps don’t use all these cores. I run that stuff. Neither do apps like Photoshop. If sometimes they use most cores, the usage ore core I’d down around 20% in spurts. Fewer cores simply have higher per core usage.As I said, video rendering is about the only thing that most users will find using a lot of cores. Even multasking doesn’t use 16 or more cores efficiently.
It’s also interesting that years ago, the argument was too much power. 150 Watters was considered to be on the high side, and not in a good way. Now these cores are moving to 300 watts, and nobody is saying anything.

Video rendering3D rendering
3D animation where physics calculation is need (cloth, particles, etc)
Particle simulations for 3D animation / work / science
Game creation / compiling / baking
Progamming (compiling)
VFX -- after effects, etc
Gaming while rendering out any of the above at the same time
Doing more than one thing at a time (Intel users close all their apps to game, lol)
Gaming while streaming
Youtube content creation (requires video rendering and encoding)
Digital audio workstations
To name a couple ...
I actually read someone on another comment feed defending Intel by saying "CPU's aren't even important these days anyway!" -- the desperation of fanbois to grasp at straws to defend the indefensible is hilarious ... right Mel?
