Specifications for AMD Radeon RX 6600 XT and RX 6600 are glimpsed

The hardware-packed autumn of 2020 delivered news on many fronts, but the new “Ampere” and RDNA 2-based graphics cards from Nvidia and AMD, respectively, were one of the biggest items. Since the launches, as you know, the storage shelves have been empty, but that has not stopped Nvidia from expanding the initial powerful trio with simpler Geforce RTX 3060 models and equivalents for laptops.

In mid-March, AMD’s Radeon RX 6900 XT, RX 6800 XT and RX 6800 were joined by the RX 6700 XT, but the company has not revealed what is lurking in the classes below. In an unofficial way, this will now change, when Videocardz presents findings from the Chinese forum Chiphell. The focus is on the Radeon RX 6600 XT and its XT-less little brother, which has been performance tested and captured on image in the monitoring software GPU-Z.

The Radeon RX 6600 and RX 6600 XT both use the new Navi 23 circuit in the company of 8 GB of GDDR6 memory, which communicates over a relatively narrow bus of 128 bits. The GPU-Z image also speaks of base and turbo frequencies for the faster card: 1,692 MHz and 2,684 MHz, respectively, where the former is just over 600 MHz lower compared to the RX 6700 XT, while the latter figure is approximately 100 MHz higher.

Furthermore, excerpts from GPU-Z show that the more powerful part of the Radeon RX 6600 duo comes with 2,048 stream processors, which translates to 32 computing units (CU) – 20 percent less than with the RX 6700 XT. The RX 6600 steps down to 1,792 stream processors and 28 CU, but the software does not capture the model’s clock frequencies.

Chiphell user “Enthusiastic Citizen” writes that he seized performance figures for development copies of the two graphics cards. In 3DMark Time Spy, the XT variant reaches 9,439 graphics points, while the sibling stays at 7,805. This can be compared with SweClocker’s performance tests, where, for example, the previous generation Radeon RX 5700 XT and Geforce RTX 2060 are in the same district with 9,278 and 7,574 graphics points. Gigabyte’s RTX 3060 Gaming OC clocks in at 9,046 points.

On June 1, AMD will take its place on the digital stage in this year’s edition of the Computex trade fair, and the presentation will probably include the promised mobile RDNA 2 graphics cards. It is also not unlikely that the company will lift the lid on the Radeon RX 6600 duo at the same time.
