AMD Radeon RX 6900 XT Video Card Front View

Introduction

The AMD Radeon RX 6900 XT was announced in November of 2020 alongside the Radeon RX 6800 XT and Radeon RX 6800 and released in December of that year. 

The AMD Radeon RX 6900 XT stands as AMD’s current flagship video card, it is the best of the best that AMD has to offer for the gamer in performance currently in the Radeon RX 6000 Series family.  It launched with an MSRP of $999, which is $350 more than the $649 AMD Radeon RX 6800 XT which sits directly below it.  We were finally able to buy one ourselves, we bought a made by AMD Radeon RX 6900 XT video card so that we can bring you a full review today.  A separate overclocking review will follow.

AMD Radeon RX 6900 XT Specs  

The AMD Radeon RX 6900 XT is positioned as the “Ultimate 4K Gaming” experience at 300W of power.  In terms of pricing, it’s at $999 MSRP while the RX 6800 XT is $649 MSRP and the RX 6800 is $579 MSRP.

The AMD Radeon RX 6900 XT is based on AMD’s RDNA2 architecture and manufactured on TSMC’s N7 FinFET node.  The Radeon RX 6900 XT is the full implementation of the Radeon RX 6800 XT, with the full amount of Compute Units.  It is known as the NAVI 21 XTX GPU model.

The Radeon RX 6900 XT contains 80 Compute Units, 5,120 Stream Processors, 80 RT Cores, 128 ROPs, and 320 TMUs.  It has 128MB of Infinity Cache.  It runs at a game clock of up to 2015MHz and a boost clock of up to 2250MHz.  It has 16GB of GDDR6 onboard running at 16GHz on a 256-bit bus.  This provides 512GB/s of memory bandwidth.  The TDP/TBP is 300W.  Recommended PSU is 850W.  It supports PCI-Express 4.0 and AMD Smart Access Memory.

The made by AMD video card comes in a very robust and thick box, which is packaged well.  It’s a simple and effective design.  When you take the video card out of the box you realize it’s exactly similar in size and weight to the AMD Radeon RX 6800 XT.  It has the same thick cooler design as the RX 6800 XT, not the slimmer design of the RX 6800.  The entire video card is wrapped in metal, and very robust and sturdy in the hand.  The all-encompassing build of the video card makes it feel very premium.

The video card is an axial-fan design with three large fans.  It does support Zero RPM to keep the fans off at idle temps.  It has a die-cast aluminum shroud and extended vapor chamber heatsink and a die-cast aluminum frame for support.  The backplate is fully realized, with only the back of the GPU exposed.  This means it won’t trap GPU heat underneath, a very good design.  It also keeps the card as slim as possible.

It uses graphite thermal interface material for the GPU.  It has high-performance ultra-soft gap pads for GDDR6 and MOSFET cooling.  It uses a 14-layer PCB with 4 layers of 2oz copper made with premium IT-170 material and high-efficiency power phases. The video card measures the same size as the Radeon RX 6800 XT, which is 10.5 inches long and 2.5 slots in height.

There are two 8-pin PCI-Express power connectors required.  For display output, it has two DisplayPort 1.4a ports, one HDMI 2.1 port, and one USB Type-C port.

  1. I would gladly buy a 6800XT or a 6900XT at MSRP. Sadly, both have been non-existent for months, let alone anywhere near MSRP when one does pop up.

    I’m over this GPU shortage.

  2. Considering availability I’ve been happy with my 6800xt, When I bought it though pricing was just starting to ramp up. I got mine after taxes for right at 900 bucks.
