best ryzen 9 3900xt build

As you’ve probably already heard, AMD is refreshing their Zen 2 Ryzen 3000 lineup with new chips that were released yesterday, on the 7th of July. These mark an intermediate generation between Zen 2 and Zen 3 and consist of better-binned chips with higher boost clock speeds and some more Infinity Fabric optimizations. With this article, we will focus on creating a high-end enthusiast PC build centred around the new Ryzen 9 3900XT CPU. This $2,700 build needs to be able to do everything gaming and workstation related and provide you with the best experience the 2020 market can offer right now.

For this to happen, we will pair this beast of a CPU with a great implementation of Nvidia’s flagship RTX 2080 Ti in order to aim for the best gaming performance that we can cram into a single build. Even though the RTX 2080 Ti comes at a hefty $1,200+ price, it rightfully provides the greatest gaming experience in any current game engine and is capable of delivering 1440p 144hz gaming and even 4K high refresh rate. We will next focus on rounding up this build nicely with great storage, superior RAM speed and a functionally premium case.

The RTX 2080 Ti card we’re using is VR ready with enough performance to get over 90 FPS in any Virtual Reality title out there; its also the best graphics card that can handle Ray Tracing in all titles without a lot of frame rate slow down. This card is also a beast when it comes to workstation performance; with its amazing CUDA and Machine Learning performance thanks to this GPU’s Tensor Cores, you can expect the best acceleration in any production software you’re planning to use.

If you are upgrading from the previous generation Ryzen processors then you’re in for a nice ride because you can reuse your motherboard in this build by just updating your BIOS and without sacrificing any performance. Back in 2017 when AMD launched the first generation Ryzen processors, they promised AM4 socket compatibility through the generations until 2020 and they really kept their word. If you are planning to get a new build or are coming from an Intel one, then you will need to get a new AM4 board and your best options for the Ryzen 9 3900XT really are the B550 and X570 chipsets with PCIe 4.0 support. We are going all out with this build and chose an X570 board for its full feature set, stellar I/O and great hardware. You won’t be sacrificing a lot of features if you want to lower the price of this build and go with a B550 but X570 will make sure you’ll be able to push the 12 core Ryzen chip to its limits and with great stability. If you are on an even tighter budget but still want the performance of the 3900XT and 2080 Ti you can go the route of a B450 or X470 board but in some cases, you might push the hardware too much if you plan to tweak and overclock a lot.

Benchmarks of the new chips should be out by now and we’ll be doing a recap soon. Single-core performance is improved by a few percent and so is multi-core over the previous Ryzen 9 3900X. The 3900XT is a dream for any content creator that loves to use their PC in order to power their business. You can create any type of 3D models and watch live and smooth renders with the speed of this CPU or you can stream in the highest quality possible on Twitch, YouTube or other platforms; all this while gaming. If a few years ago you’d need two PCs in order to do your gaming and content creating job, look no further because this build focused around the 12 core 24 threads Ryzen CPU will breeze through anything you’ll throw at it; it really does have that much horsepower and you’ll need to feed it unusual amounts of work in order to slow it down. Its single-core performance closely matches the top Intel consumer CPU, the i9 10900K while the multicore performance is around 15% to 20% better all while consuming far less power and being much easier to cool. This CPU redefines the consumer market as the first mainstream 12 core CPU with no apparent weaknesses and it comes without costing a fortune. If you need a workstation that’s able to use all of this CPU’s power, the $499 price tag really is a steal for the performance you’re getting out of this chip.

CPU

The new Ryzen 9 3900XT processor

AMD Ryzen 9 3900X

The popular Ryzen 9 3900X processor just got a new brother in the form of the Ryzen 9 3900XT. Higher boost clock speeds, better silicon binning and improved Infinity Fabric clocks will give the Ryzen 9 3900XT a slight edge over the outgoing 3900X model. The base speed remains the same at 3.8 GHz but the boost clock is up from 4.6 to 4.7 GHz. The benchmarks that appeared after NDA lift showed that the Ryzen 9 3900XT can sustain its high clocks better and this showed in gaming where performance was 2 to 3% better than the previous 3900X model. The reason for this slight gaming performance uplift may also come from the fact that the Infinity Fabric interconnect that AMD is using in order to connect all the processor cores now runs at 2 GHz out of the box and this means latency is lowered.

This CPU is a stellar choice if you are sure that you’ll be using your PC for a lot of tasks at the same time. The 3900XT will parallelly game, stream, render and do workstation work without any issues or slowdowns and in parallel. Its the ultimate content creator’s dream processor and we highly recommend it.


CPU Cooler

The beQuiet! Dark Rock Pro 4 CPU cooler

NZXT Kraken X63

A lot of people were surprised that AMD won’t be including any stock coolers with their new Ryzen 7 and Ryzen 9 lineup; that’s the 3800XT and the 3900XT. One explanation is the fact that these CPUs can be pushed harder than the previous ones and AMD is recommending third party coolers in order to ensure better thermal dissipation with these chips.

The Kraken X63 280mm AIO cooler is the 3rd revision of NZXT’s popular Kraken series and its an AIO LC for cases that allow mounting 280mm radiators. The included software this cooler is bundled with allows you to heavily customize all performance and visual aspects of the cooler and pump LED display. Its also one of the most beautiful and recognizable AIO coolers for its infinity logo design; stress-free to install, silent thanks to the optimized airflow of the fan blades and powerful performance modes are key ingredients for X63’s success. When idle, this cooler provides normal noise levels and temperatures but what impresses us the most is how this device handles overclocking loads on the processor; even during stress testing, the temps remain great. When overclocked to 4.6GHz and 1.4V on the Ryzen 9 3900X CPU, we remain under 75 degrees Celsius with an untouched fan profile. Setting it to more aggressive (and noisy) fan profiles, we can take the temperature even lower but that’s not needed if this cooler performs that well at stock.

Overall, we can recommend the NZXT Kraken X63 with no hesitation as a high performance all in one cooling solution for the Ryzen 9 3900XT but if you can’t fathom spending $150 for a CPU cooler than you also have the option of the Arctic Liquid Freezer II which is also a 280mm liquid cooler, albeit with less visual ‘bling’ but with similar performance and noise levels; that cooler retails for $95 making it a much easier buy.


Motherboard

The Gigabyte X570 AORUS ELITE WIFI with the new PCIe 4.0 chipset and feature set

Gigabyte-X570-AORUS-Elite-WiFi

You simply can’t go wrong with Gigabyte’s motherboard products. The model we’re using is based on AMD’s X570 chipset and can easily handle a 12-core 24-thread CPU like the Ryzen 9 3900XT – at any levels of load. Amazing build quality, highly customizable BIOS and solid VRMs are just some of this motherboard’s advantages. It might not be an affordable motherboard like the other B550 counterparts but you are getting the full feature set of the AM4 socket and its a highly suitable board for the 3900XT.

I/O is great and it includes 2 x USB 3.1 G2 Type-A, 4 x USB 3.1 G1 Type-A, 4 x USB 2.0 ports, an HDMI video output and an Intel Gigabit NIC Ethernet port. The onboard audio is of stellar quality and is driven by one of the newest audio codecs, the Realtek ALC1200 HD. This version also includes two antenna adapters for the Intel AX200 WiFi 6 wireless ethernet. For the $209 MSRP, this X570 motherboard ticks all the boxes needed for an enthusiast gaming and workstation build.


Memory

32 GB of G.Skill Ripjaws V 32 GB 3600 MHz memory

G.SKILL Ripjaws V 16GB 3200MHz CL16

This build clearly needs the capacity and speed of a high-end memory kit in order to perform as needed in any high load situation. Introducing the 2 x 16GB RAM kit from G.Skill, the Ripjaws V is factory tuned to 3600MHz CL16 thus providing a very low latency that will greatly benefit our Ryzen 9 3900XT. Editing, gaming multitasking and various multi-core applications will eat memory like crazy if you’re going to use this system as intended and this RAM kit will make sure that you’re always going to have enough capacity and bandwidth for any of your tasks.

The 3,600 MHz Dual Channel kit from G.Skill provides all these gaming and workstation advantages in an inexpensive package; its really hard to find better memory than this for a lower price. With latencies of 8.88ns coming from the stock 3,600 MHz CL16 setup, this RAM kit will also boost the processor performance since Ryzen’s Infinity Fabric works faster in the presence of tighter memory timings. This kit can also be further tweaked in order to squeeze even more performance out of it by simply increasing the voltage and tweaking the timings.


Storage

One fast NVME SSD, the Samsung 970 Evo Plus and one M.2 SSD, the Crucial P1 1 Tb

Samsung 970 EVO Plus SSD

As an OS drive, we will be using one of the fastest storage devices on the market which is the Samsung 970 Evo Plus 500GB. We want this drive as the boot drive for no-compromise system responsiveness and with the 3,500 MB/s read & 3,300 MB/s write speeds the 970 Evo Plus is capable of delivering the greatest experiences for your gaming and workstation endeavours.

Crucial P1 1TB NVMe SSD

For the secondary storage device, we will be using another popular M.2 SSD, in the form of the Crucial P1 1Tb; we like this device a lot for its inexpensive fast storage that only has a niche weakness, transfers of over 50GB at one time. During these, the drive will slow down but truth is, 99% of consumers will never feel this drive slowing down from its advertised 2,000 MB/s read & 1,700 MB/s write speeds because they won’t be exceeding the 50 GB cache transfer limit.

The two drives together offer 1.5 Tb of very fast storage, 500 GB for the boot drive / main applications and 1Tb for secondary applications or file use. They complement each other very well and if you are in need of more storage then feel free to add a few SATA SSDs to your heart’s desire. We can’t know for sure what your storage needs are so we’re just recommending what most users will use for an enthusiast PC.


Graphics Card

Nvidia’s enthusiast GPU, the RTX 2080 Ti

msi-rtx-2080-ti-gaming-x-trio

One of the best RTX 2080 Ti implementations with carefully thought-out board components, a tuned experience out of the box, good acoustics and a decent price; these are the ingredients that make the MSI RTX 2080 Ti Gaming X Trio our easiest AIB recommendation for a 2080 Ti GPU. We would recommend pairing this card with at least a 650W PSU in order to ensure a steady flow of current but because this build also features a 12 core CPU, then 750W would be more in line with this build’s needs and efficiency zone.

The Gaming X Trio offers good I/O connectors and certainly every port that most gamers need in the form of three Display Ports, one HDMI and one USB Type-C mainly for VR use. This combination is standard among many other RTX 2080 Tis but the aspect that differentiates it is the 2 x 8-pin + 1 x 6-pin power connector setup that can’t be found on other similarly priced cards; this bodes well for overclocking headroom and shows that MSI knows what they’re target audience is. The 1,350 MHz base clock matches Nvidia’s reference model but the boost clock is much higher and the nice thing is that this card is able to easily sustain it thanks to its carefully crafted triple-fan cooler. Whoever will choose this MSI model as their RTX 2080 Ti will be rewarded with the best GPU performance on the market paired with silent operation and attention-seeking RGB lighting; in short, fiercely delivering on its potential and price tag.


PC Case

The Lian Li LANCOOL II-X ATX Mid Tower case & additional fans

Lian Li Lancool 2 II-X

Lian Li has packed an impressive amount of features we’d expect from more expensive cases into a $90 package with their LANCOOL II-X. From the hinged magnetic tempered glass panels to the front fan tray and LED implementation are very nice and showy. Airflow is great in testing thanks to its dual mesh front panel and 3 x 120mm fan cooling setup; we also added a bundle of RGB case fans to this build in order to adjust the airflow even better and use 3 fans for intake and 3 for exhaust.

Various fan mounting points that extend the whole height of the front panel, multiple tie-down points for cable management and another hinged back window are some of these case’s highlights that put it so high on our recommendations. It really sets the benchmark for what a $90 case can do.

  • Dimensions: 478 x 229 x 494 (D x W x H)
  • Weight: 12.6 KG (27.8 lbs)
  • Compatibility : CPU Cooler Max height 176 mm | GPU Max length 384 mm
  • Included Fans: Included 1 x 120 mm Rear, 1 x 120 mm Front, 1 x 120 mm Top.
  • Dust Filters: 1 x Top (magnetic), 1 x Front Panel (magnetic), 1 x Bottom (tray)

Power Supply

Powering this PC with the Corsair RM 750W 80+ Gold Certified

Cooler Master MWE Gold 650W PSU

We want to make absolutely sure that this 3900XT build is powered and sustained well and this is why we chose an A tier PSU, the Corsair RM 750W with Gold certification, full modularity and 750W rated power output. The average power consumption of this build during load will sit somewhere around 350 W so a 750 W power supply is needed in order to stay in the 40-60% efficiency range of a PSU.

Its efficiency at light loads is impressive due to the burst-mode operation of its LLC resonant converter. Currently, depending on the hardware, the S3 sleep state takes from anywhere between 7–15 seconds to turn on the PC. This is a significant improvement that will make our PCs behave like mobile phones. Touch the keyboard or the mouse and the system will wake up in no time.

With its capability to provide full power at just 47 degrees Celsius, quiet operation and great overall performance, the Corsair RM750 is an impressive piece of kit for enthusiast builds, especially because it’s backed up by a hefty 10-year warranty.

  • Dimensions: 152 mm x 87 mm x 162 mm (W x H x D)
  • ATX connector 20+4 pin: 1
  • 4+4 pin EPS12V: 2
  • 6+2 pin PCIe cables: 6
  • SATA Connectors: 9
  • 4 pin Molex: 4
