In the wake of AMD’s 3rd Generation Ryzen processor success, the spotlight is now squarely on Threadripper 3000. Although AMD has been unnaturally cagey regarding Threadripper, details have started leaking out.
Gamers Nexus managed to unearth a particularly juicy bit of info regarding the new Threadripper 3000-series platforms. Yes, that’s plural – sTRX4 and sWRX8.
Threadripper vs. Ryzen (TR4 vs. AM4): Do You Need HEDT?
The launch of the 16-core Ryzen 9 3950X processor does complicate things for those who are considering workstation/HEDT builds. Even though Ryzen’s raw processing performance is undoubtedly an attractive proposition, AMD’s TR4 HEDT platform still has its place.
Memory Channels and PCI-E Lanes Explained
Threadripper launched with plenty of cores and a robust HEDT platform that blew away the competition. So, what did it offer that the Ryzen (AM4) platform didn’t?
Here are the two most differentiating TR4 platform features:
- Quad-channel (4-channel) memory support (vs. dual-channel on AM4)
- 66 PCI-E 3.0 lanes (vs. 28 lanes on AM4)
As most users don’t need these features, they’re better off sticking to AMD’s Ryzen platform (AM4). However, workstations that must handle complex workloads will eventually find themselves strapped for power when going with a Ryzen system.
Quad-channel memory allows memory access across 4 channels, simultaneously, making it invaluable for memory-intensive workloads.
Here’s a look at how bandwidth scales with memory channels:
Please note that you’ll only see an improvement in performance when the RAM used by any application exceeds the bandwidth of dual-channel memory. As if that wasn’t limiting enough, said application should be optimized to make use of this additional bandwidth as well.
Make sure you check for benchmarks before you settle on a platform for the sole purpose of quad-channel memory.
Similarly, only certain multi-GPU setups benefit from additional PCI-E lanes. Since the AM4 platform has fewer PCI-E lanes, running multi-GPU setups require running each GPU at x8 instead of x16. Although not many graphics cards other than the RTX 2080 Ti or the Titan RTX can completely saturate an x8 PCI-E 3.0 lane, installing additional GPUs does become a limitation.
For anyone considering a system built around 3 or more powerful GPUs, I’d recommend a Threadripper over a Ryzen. However, if your workloads can fit into your video memory, then even a 3-GPU setup is feasible on Ryzen.
Next-Gen Threadripper 3000: What Do We Know?
Threadripper is the ideal choice for those not needing the power of a full-scale server build as well as those who find the capabilities of the Ryzen platform too limiting.
But there’s a slight hiccup. The newest-generation Threadripper processors haven’t even been announced yet. So, you’d have to settle for the performance of 2nd Generation Zen parts.
Since viewport performance generally relies on single-core performance, Threadripper CPUs weren’t a clear-cut choice that I wish they could be. You can find the viewport performance for popular processors on our Cinema 4D Viewport Benchmarks page.
At the moment, those who needed the astounding render performance of Threadripper had no choice but to bifurcate their builds into a primary workstation build, focusing on single-core performance, and a rendering build that focused on multi-threaded performance.
If 3rd Generation Ryzen was any indication, the newest Threadripper CPUs look promising at the very least. An IPC uplift of this scale, combined with the capabilities of AMD’s HEDT platform, makes waiting for these new processors worth it. This could very well mean that we’d finally get snappy viewport performance and blistering render performance in one neat package, at a reasonable price for the very first time!
Now that we’re starting to get details of the new Threadripper platform, it’ll be easier to figure out whether waiting is the way to go.
Threadripper 3000 Processor Release Dates
Here’s what we know for sure (regarding release dates): AMD will announce the new 3rd Generation Threadripper CPUs before this year (2019) ends. An official slide lists them as one of the last products to be launched in 2019.
The wording AMD officials have used in recent interviews indicates that these processors will only be announced this year, but won’t be available to purchase until early next year. However, this is just conjecture, and I can’t be sure.
Since we’re speculating anyway, here’s another one. AMD has launched products at the 7th of the past few months. Their marketing team seems to love that date – allowing them to stress 7nm technology with every release.
The next launch (7th October) will be the monstrous Ryzen 9 3950X 16-core CPU. I think we’ll see a Threadripper 3000 announcement by the end of November at the latest.
Threadripper 3000: Better in Every Way?
Yes. I have absolutely no doubt that the single-core performance of these chips will match the other Zen 2 products (Ryzen 3000) from an IPC standpoint.
Of course, they might be clocked lower rather than higher or equal to them, to account for additional cores. A quick comparison between 2nd Generation Ryzen and 2nd Generation Threadripper CPUs shows that the clock difference won’t be too vast, if any does exist.
Threadripper 3000 Platform Leaks: sTRX4 and sWRX8
Instead of sticking to a single HEDT platform, AMD has decided to go with two platform options this time around. While one is like the present TR4 platform, the other takes it a step further.
Here’s a quick look at the platform details:
Since the sTRX4 and the present sTR4 platform don’t seem to be radically different, we do hope that AMD makes the new Threadripper CPUs backward compatible with older X399 (TR4) motherboards. However, the workstation platform offers a lot more in comparison.
Here are a few key features of the sWRX8 platform:
- 8-channel DDR4, ECC Memory Support – Doubling the quad-channel capabilities of TR4.
- Support for UDIMM, RDIMM, LRDIMM – Certain workloads will need access to Registered (RDIMMs) or Load Reduced (LRDIMMs).
- OC Support Disabled – Since workstation tasks require stability over all else, the sWRX8 doesn’t support overclocking.
- 96-128 PCI-E Lanes – Although I’m not sure why this variation exists (probably has to do with individual Threadripper SKUs), the sWRX8 comes with over 50% additional lanes over TR4 at the very least.
The Verdict: Should You Wait for Threadripper 3000?
Here’s the short answer – absolutely! If you can.
I understand, though. Many of us need our workstation builds right away, and waiting isn’t an option. In that case, there’s nothing you can do but work with the options we have now.
If you do need access to Threadripper platform features like additional PCI-E lanes, higher core counts, or extra memory bandwidth, we still recommend bifurcating your builds.
One build will handle your viewport – making it your primary workstation PC. You could build this around a 3rd Generation Ryzen processor or a 9th Generation Intel processor.
The second build will act as your render node. Build it around the Threadripper platform and make full use of its features.
Another option is going with an Intel HEDT build. However, its X299 chipset is pretty limiting and offers fewer PCI-E lanes (44), no ECC memory support, and comes at an insane cost, compared to AMD’s HEDT platform. But that’s another topic (rant) for another day.

Unfortunately, until Threadripper 3000 comes along, these are the only options we have.
