ASRock Phantom Gaming Radeon RX 6600 XT Review – Quiet fans, no noise
A GPU with contemporary features like ray tracing, DirectX 12 Ultimate support, variable rate shading, and HDMI 2.1 is the Radeon RX 6600 XT. Even on lower resolutions that are still frequently used, like 1080p monitors, it enables gamers to enjoy better visuals at comfortable frame and refresh rates.
The GPU has 2,048 “stream processors” with individual ray accelerator logic split into 32 compute units. It has a 2,359MHz reference “game clock” and a 2,589MHz maximum boost clock. The on-die Infinity Cache of the Radeon RX 6600 XT is 32MB, which is less than that of the Radeon RX 6800 and RX 6800 XT but is still effective. Hardware H acceleration is also supported by the GPU. 264, H. For specific resolutions and frame rates, 265, VP9, and AV1 decode. It has 8GB of GDDR6 memory on a 128-bit bus, giving it a memory bandwidth of up to 256GBps, and it uses the same 7nm manufacturing process as its siblings. Although the particular board partners’ designs may change this, AMD recommends a 160W TDP. Only platforms that support PCIe 4.0 can benefit from AMD’s decision to use only eight PCIe lanes for the Radeon RX 6600 XT. This option offers the same bandwidth as PCIe 3.0’s 16 lanes, but on an older system, PCIe 3.0’s eight lanes will only offer half the bandwidth, causing slight bottlenecks.
To take advantage of AMD’s Smart Access Memory feature, which allows a CPU to access the GPU’s entire memory capacity rather than the conventional 256MB limit, a relatively modern PC is required. Up to 10% more performance can be achieved in some games by implementing the Resizable BAR (Base Address Register). Since this mid-range tier lacks a reference design, all Radeon RX 6600 XT GPUs will have unique coolers. With a strong emphasis on customization and design, ASRock has created a large card that is 305mm long, 40mm longer than most high-end cards, and taller than average cards, taking up three motherboard slots. The central fan is the only one with RGB LED lighting, and the other two fans on the front of the card have notches to improve airflow and lower noise. The central fan’s RGB LEDs always show a circular pattern, whether the fan is spinning or not. The top panel of the card also features RGB LEDs and the ASRock Phantom Gaming logo. For synchronizing and controlling the lights with ASRock motherboards that are compatible, downloadable software is available.
The card’s actual PCB only makes up 190mm of its length; the remaining space is occupied by aluminum heatsink fins under the shroud. Because of this, even though it is at the end of the board, the single 8-pin PCIe power connector looks to be in the middle of the card. Due to the card’s weight of 894g, the metal backplate lends rigidity to the entire construction.
