Introduction
PowerColor Red Devil Radeon RX 6600 XT
The devil is in the details
AMD has announced the Radeon RX 6600 XT. In this review, we'll look at PowerColor'ss newest 6600 XT Red Devil card, which is positioned to compete directly with the custom 3060 premium models.AMD unveiled its next member of its RDNA 2-based graphics family, their Navi23-based graphics card(s)the 6600 XT. Historically, the 6600 series was positioned between entry-level and mainstream, generally in the 150–200 USD range. You now need to pay 379 USD for a graphics card aimed at the Full HD range. The cards, which are thus positioned as a 1920x1080 offering, and will include a GPU based on NAVI23.
Radeon RX 6600 XT
The Navi 23 GPU-based graphics cards are manufactured on a 7nm process and have a maximum of 8 GB of gddr6 memory and are connected through a rather restricted 128-bit memory interface. 8 GB GDDR6 RAM will be used, buffered by a 32 MB Infinity Cache. The series card is projected to perform at the performance marker of the RX 5700 XT and GTX 1080 Ti, making it an excellent card at 1080p or good card at 1440p. The RX 6600 XT features 2048 stream processors, whereas the unknown RX 6600 is expected to include 1792 of them. Numerous firms have stated their own variants and setups of the card. We've mapped the major specs below to help you see what to expect.

NAVI23
The "Navi 23 XT" chip is not new; it is already in use as the Radeon RX 6600M graphics solution for notebooks, which was introduced with the Radeon RX 6800M and 6700M graphics solutions for laptops a few weeks ago. The majority of cards will use a dual-slot dual-fan cooler; they will include a single 8-pin PCI-Express graphics connection with a maximum power consumption of 160 watts. The Radeon RX 6600 XT features 2048 rather than 2560 stream processors or shader units and a memory interface decreased from 192 to 128 bits. AMD will initially offer the 6600 XT cards, followed by the 6600. The Radeon RX 6600 XT is to cost a rather extravagant 379 USD as a base reference product. Thus, you can expect board partner cards with custom designs and cooling to sit well above the 400 USD marker. We can already share that the pricing is the biggest culprit of this product series.
PowerColor Radeon RX 6600 XT Red Devil
TUL, the primary company responsible for PowerColor, has returned with somewhat of a demonic offering. Meet the Red Devil. Equipped with a factory tweak, a dual BIOS, and a relatively compact design, the card appears to have been created with the intent of awe-inspiring users. The card has two BIOS modes: Overclocking and Silent, with power targets ranging from 135W to 145W. PowerColor built the card to be extremely quiet, and even in performance mode, it is far quieter than the majority of silent cards. RGB has also been improved; Red Devil now connects to the motherboard's aRGB (5v 3 pin connector) enabling RGB Sync, which was previously not possible. Based on a 10 Phase VRM design as opposed to the 6+2 Phase VRM design on the typical designs, it has been spec'd to offer the most pleasing results. Stability and overclocking headroom are important. Additionally, the connecting ports are lighted with LEDs. You'll be able to see where to plug in now even in the dark.
The RX 6600 XT graphics card has been changed to have an outspoken black and red design, as well as a backplate. The card has three DisplayPort 1.4 ports as well as one HDMI 2.1 port in the I/O section. As of this writing, the clock frequencies are specified as 2188 MHz Base, 2428 MHz Game, and 2607 MHz Boost. The Boost frequency, on the other hand, is no longer a fixed setting; instead, the power limiter is the most important component to consider. Frequencies have a range of values that vary depending on the power allowance. The 8GB of GDDR6 memory operates at a frequency of 2000 MHz (16 Gbps effective). The card measures around 25cm in length. Check out what is being discussed today to get a sense of what we have to talk about. On the following two pages, we have some images taken in-house, and then we move on to the evaluation.
