How To Optimise For 64 Cores : An AMD Guide!

Leave a reply

The new AMD Ryzen Threadripper 3990X gives design and video production professionals, as well as HEDT enthusiasts, unprecedented computing power with 64 cores of processing power!

But with all those cores come the problem – how do you make use of all 64 cores, and not have any core just idle, wasting power?

Thanks to their work with the RED Digital Cinema team, AMD has some advice on what we can do to optimise for 64 cores.

 

AMD Ryzen Threadripper 3990X : 64 Cores of Awesomeness!

The AMD Ryzen Threadripper 3990X is the world’s first 64-core HEDT processor, bringing the capability to process up to 128 simultaneous threads simultaneously to the desktop!

AMD demonstrated that it not only handily trounces the Xeon W-3275 processor – Intel’s best single-chip processor, it also handily beat the two Xeon Platinum 8280 processors!

To keep all 64 cores humming, every core has 512 KB of L2 cache, with a super large 256 MB L3 cache to keep data flowing.

However, you cannot just build an AMD Ryzen Threadripper 3990X system, and expect to instantly leverage all 64 cores.

 

How To Optimise For 64 Cores : An AMD Guide!

After working with the RED Digital Cinema team, AMD came up with some advice on how to optimise your system for 64 cores.

Optimising For 64 Cores Summarised

1. Ensure there is 1 GB to 2 GB of RAM per thread – the system should have 128 GB to 256 GB of memory.

2. Update to Windows 10 version 18362.535 or better (KB4530684 November 2019 Update)

3. The Windows application should be updated to support 65 or more threads, with the ability to span more than one processor group

4. For Linux users, Clear Linux Distro is the best for performance.

5. Reduce storage I/O bottleneck by disabling the virus scanner and system restore feature.

6. Use separate drives for project read, project write and operating systems.

7. AMD recommends these NVMe SSD models for maximum performance with 64 cores :

 

Where To Buy?

The 64-core AMD Ryzen Threadripper 3990X is priced at RM16,999 / S$5,988 / US$3,990, with these online purchase options :

AMD Threadripper 3990X : World’s First 64-Core HEDT CPU!

Leave a reply

The AMD Ryzen Threadripper 3990X – the world’s first 64-core, 128-thread HEDT processor is finally here!

Here are the full details on this crazy 64-core HEDT processor – the official tech briefing, the official promo video, specifications, price and more!

 

The 3rd Gen AMD Ryzen Threadripper Processor Family

The AMD Ryzen Threadripper 3990X is the world’s first 64-core HEDT processor, headlining the 3rd Gen Threadripper family, which now looks like this :

  • Ryzen Threadripper 3990X : 64C / 128T, 2.9GHz / 4.3GHz, 288 MB cache
  • Ryzen Threadripper 3970X : 32C / 64T, 3.7GHz / 4.5GHz, 144 MB cache
  • Ryzen Threadripper 3960X : 24C / 48T, 3.8GHz / 4.5GHz, 140 MB cache

Like the 3rd Gen AMD Ryzen processors, the AMD Ryzen Threadripper 3990X processor is based on the new Zen 2 architecture with the chiplet design approach.

The CPU dies are fabricated on the 7 nm process technology, while the I/O die is fabricated on the 12 nm process technology.

There is no better person to tell you how awesome it is to have 64-cores of processing power in the new Ryzen Threadripper 3990X than Robert Hallock, AMD Senior Technical Marketing Manager.

 

New Socket sTRX4 + AMD TRX40 Chipset

The AMD Ryzen Threadripper 3990X requires a AMD TRX40 motherboard with a new sTRX4 processor socket. However, you will still be able to use existing Threadripper coolers.

The processor comes with 64 PCIe 4.0 lanes, of which 56 are available for use. The AMD TRX40 chipset adds another 24 PCIe 4.0 lanes, with 16 free lanes.

In total, the new Socket sTRX4 and TRX40 chipset will give you 72 free PCIe 4.0 lanes to use, compared to just 56 free PCIe 3.0 lanes in previous generations.

In addition, the new AMD TRX40 chipset communicates with the 3rd Gen Threadripper using a PCIe 4.0 x8 link. This gives it 4X more bandwidth than the PCIe 3.0 x4 link used in the first two generations.

AMD Ryzen Threadripper 3990X Performance

In this video, Robert shows how the new 64-core Threadripper 3990X and even the 32-core Threadripper 3970X handily beat the Intel Xeon W-3275 processor – their best single-chip processor.

 

AMD Ryzen Threadripper 3990X Price + Availability

The 64-core AMD Ryzen Threadripper 3990X is priced at a princely RM16,999 / S$5,988 / US$3,990, which is almost double that of the Threadripper 3970X!

You can grab one from AMD or their retail partners starting from 7 February 2020 onwards, and start making your own Terminator : Dark Fate movie! 😀
