ASRock Radeon RX 6750 XT Phantom Gaming D 12GB OC Video Card Front View

Introduction

ASRock has been a well-known and well-established brand name for motherboards.  ASRock targets mainstream to enthusiast motherboard segments in Taipei, Taiwan, Europe, and the USA.  While ASRock is most noted for its motherboards, it has a large line of AMD ported GPUs dating back to the Radeon RX Vega and RX 500 series.  ASRock carries a complete lineup of current generation Radeon RX 6000 series GPUs today, with some very appealing aesthetics and branding.  This is TheFPSReview’s first look at an ASRock video card, though we have reviewed ASRock’s motherboards on our site.

Today we will be reviewing the ASRock AMD Radeon RX 6750 XT Phantom Gaming D 12GB OC video card (RX6750XT PGD 12GO).  This video card sits at the top SKU of what ASRock offers in the Radeon RX 6750 XT models.  If we look at the Radeon RX 6750 XT under ASRock’s homepage, you will find the Challenger Pro model, and then this Phantom Gaming D OC Edition model.  Both video cards have custom designs, with custom cooling, and both have factory overclocks.  However, the Phantom Gaming D has a unique design, RGB that is addressable, and a higher factory overclock.  The one we are reviewing today is the top-of-the-line Phantom Gaming D model.    

AMD Radeon RX 6750 XT

The AMD MSRP for the Radeon RX 6750 XT is $549.  The AMD Radeon RX 6750 XT is based on NAVI 22, and the RDNA2 architecture at 7nm.  It has 2,560 Stream Processors, 40 Compute Units, 40 Ray Accelerators, 64 ROPs and 160 TMUs, and 96MB of Infinity Cache.  The Radeon RX 6750 XT runs at a Game Clock of 2495MHz and a Boost Clock of 2600MHz.  In addition, the 12GB of GDDR6 on the Radeon RX 6750 XT runs at 18GHz.  This brings the memory bandwidth up to 432GB/s on the Radeon RX 6750 XT.  Due to these clock frequency increases, this brings the TDP up to 250W on the Radeon RX 6750 XT.

ASRock Radeon RX 6750 XT Phantom Gaming D

As we mentioned, the Phantom Gaming D is the top-end SKU from ASRock in regards to the Radeon RX 6750 XT.  It has the highest factory overclock from ASRock.  It has a Game Clock of up to 2554MHz and a Boost Clock of up to 2623MHz.  The reference Radeon RX 6750 XT runs at a Game Clock of 2495MHz and a Boost Clock of 2600MHz.  Therefore, the ASRock video card has a 59MHz higher Game Clock and 23MHz higher Boost Clock.  However, keep in mind that with the dynamic nature of clock speed, it can run much higher based on thermals and power it is dynamic.  The 12GB GDDR6 memory runs at the same 18GHz reference spec.

The ASRock Radeon RX 6750 XT Phantom Gaming D OC Edition video card is exactly 12” inches in length, 5.1” in width, and 2.1” in height.  It is considered a 2.75-slot video card.  On board, you will find 3x DisplayPort 1.4 with DSC, and 1x HDMI 2.1 VRR display ports.  It does require 2 x 8-pin power connectors.  ASRock recommends a 700W PSU.  The video card weighs 2.6 pounds.

This video card is based on ASRock’s Super Alloy power delivery design.  It uses a 2oz Copper PCB and Matte Black PCB with a High-Density Glass Fabric design that reduces gaps between PCB layers.  ASRock is using premium 90A power chokes to enhance Vcore voltage to the graphics card.  With Dr.MOS integrated power state solution it intelligently delivers higher current power and drives up to 60A continuous current for each phase.

The ASRock Radeon RX 6750 XT Phantom Gaming D uses the ASRock Phantom Gaming 3X Cooling System.  As you can see, this is a triple axial fan design using a Striped Axial Fan Design with a Stripe Structure on the fan blades plus a polishing surface on the bottom side.  This enhances airflow, to keep it quiet yet powerful.  The fans also support 0dB Silent Cooling that shut off at cool or light workloads and ramps up during hard workloads.

The large heatsink assembly has a Nickel-plated Copper Base and makes direct contact with the GPU area.  The heatsink assembly uses High-density Metal Welding to improve heat dissipation.  There are Air Deflecting Fins that guide airflow through with V-shaped cuttings and V-shaped air vents.  The Ultra-fit heatpipes are consolidated to make direct contact with the GPU baseplate and GPU.  ASRock uses Nano Thermal Paste and Premium Thermal Pads to the components, including the VRMs.  ASRock even uses a precise screw torque technique to optimize mounting pressure. 

To enhance structural integrity, ASRock uses a Reinforced metal frame on the edge, which looks quite robust.  In addition, there is a full Metal Backplate that does use thermal pads to enhance cooling, and a cut-out for air passthrough.

Some features this video card supports is ASRock Polychrome SYNC ARGB LEDs.  You can fully customize the RGB on this video card to different patterns and colors.  It can also be synchronized to your ASRock motherboard that supports the same feature.  ASRock has also placed an ARGB pin-header on board to connect ARGB strips and devices to sync lighting.  If you don’t like all this fancy RGB, ASRock has you covered as there is a simple switch on the video card that lets you turn the RGB on or off.
