With the Radeon RX 6600 XT (test) , AMD has expanded the current RDNA-2 architecture at the lower end of the performance range. The graphics card duels with the GeForce RTX 3060 (test) and shows advantages, but also disadvantages compared to the Nvidia accelerator in the test. Now the first pictures have appeared showing an even slower Radeon.
Clear reference to Navi 23 on the desktop
For example, Videocardz was able to bring up images of a Radeon RX 6600 or, more precisely, images of a custom design from Gigabyte, the content of which can hardly be distinguished from Gigabyte’s Radeon RX 6600 XT Eagle at first glance. However, the label “XT” is missing on the packaging and the PCB is a little shorter. An 8-pin power plug is again available and the design itself, including the cooler, is identical.
A possible Radeon RX 6600 is so interesting that AMD does not offer a non-XT variant of the larger Radeon RX 6700 XT and that does not seem to make much sense in purely economic terms either, because it cannot be assumed that Navi 23 produces a lot of scrap in the established 7 nm process, especially since the mobile Radeon RX 6600M is used for GPUs with four deactivated CUs. Every Navi-23 GPU that lands on a Radeon RX 6600 ultimately only results in lower sales and profits in a market environment in which every available graphics card is bought.
Fewer shaders than the 6600 XT, but again 8 GB of VRAM
Like the Radeon RX 6600 XT, the Radeon RX 6600 will use the currently smallest RDNA-2 GPU, Navi 23. In contrast to the larger model, the GPU is no longer fully activated, instead of 2,048 FP32 ALUs there should only be 1,792 ALUs – this corresponds to four deactivated CUs and thus exactly the configuration of the Radeon RX 6600M. The clock rates are still unknown, the same applies to the power consumption – but it should be higher in the desktop than the maximum 100 watts of the mobile version.
Since the XT version already works with a 160 watts record-breaking energy efficiency of , it can be assumed that the “non-XT” will go one better on this point despite the 8-pin power plug.
The curtain could fall in September
The graphics card should still have 8 GB of memory, although it should not be ruled out that there will also be 4 GB models. A release date is still unclear, but if Gigabyte and other on-board partners are already preparing custom designs, a release is likely this year. A few months ago it was September or October in the rumor mill.
