AMD Radeon RX 6600 XT with official images and data – RDNA2 in battle with GeForce RTX 3060

Disclaimer: The following article is machine translated from the original German, and has not been edited or checked for errors. Thank you for understanding!

We’re not officially allowed to publish much yet, but I’ve already summarized everything AMD has allowed us to know about the upcoming Radeon RX 6600 XT for today. Today, that means, AMD will unveil this graphics card at Chinajoy 2021. The event will take place this weekend, starting on Friday July 30, 2021 and it is considered certain that the card will finally be unveiled at the event as well.

There’s no mention of the RX 6600 Non-XT yet, but we’ll see what else AMD has in store. After all, the embargoes associated with this new RX 6600 XT have already been leaked extensively in the appropriate media: AMD’s announcement today, the unboxing reviews on August 6, and the launch on August 11, though it’s also been rumored often enough that testing and final details could probably be released as early as August 10, 2021. We’ll see.

The AMD Radeon RX 6600 XT relies on the Navi 23 XT GPU, which has 32 compute units or 2048 stream processors. The card also features 32MB of Infinity Cache and 8GB of GDDR6 memory running over a 128-bit wide bus interface. The Navi 23 GPU itself measures 237 mm2 and consists of 11.06 billion transistors. However, the GPU is still not the smallest chip in the RDNA 2 family, as Navi 24 is still expected here for the absolute entry-level range.

 

The memory speed will be at the usual 16 Gbps, which will then give a total bandwidth of 256 GB/s. Regarding the presumed performance data, it’s definitely worth taking a look at the slides in the gallery (see below). Even if AMD always cherry-picks such things (they deserve it), the values have actually always been right in the last time. They’re looking to go head-to-head with NVIDIA’s GeForce RTX 3060 and it’ll be interesting to see what the full range of benchmarks come up with then.

The ancestor gallery of the RDNA2 family looks like this after the launch:

Of course I will stay tuned and will actively accompany the launch. You know, this time also with teardown again….

Ne richtige Karte für den Käufer Markt. Leider
Bin gespannt auf die benches ob überhaupt die 5700 oder Vega geschlagen werden kann.

Ich brauche u.a. eine Karte für einen PCIe-3.0 Rechner. Da ist die PCIe-8-fach-Anbindung schon wieder suboptimal.
Die R9-280 ist doch langsam am Ende.

Auf die Leistung an PCIe 3.0 bin ich auch gespannt.

In der Tabelle ist ein Fehler bei der 6600XT:

Memory Bus 192-bit

Die Karte hat doch nur 128-Bit SI.

Mit der RX 5500 XT hatte ich ~ 6 % weniger an Performance als sie über PCIe 3.0 lief und das waren je nach Spiel 3 - 9 FPS die mir so nicht aufgefallen sind und nur messbar waren.
Bei der RX 6600 XT wird es schätze ich ähnlich sein und der kleine Infinity Cache könnte noch für Überraschung sorgen ( PCIE 4.0 vs 3.0 ).

Höre bzw. lese ich zum ersten mal, dass die 6900XT (mit XTXH) 18 Gbps Speicher hat/haben soll ?!?

MfG Föhn.
