It would appear that AMD’s budget RDNA offerings aren’t going to be very “budget” after all. According to YouTuber MILD, the Radeon RX 6600 XT is presently slated to launch for a price of $379 sometime later this quarter. The 6600 XT is expected to be faster than the $329 GeForce RTX 3060, at least at 1080p, but may fall behind at 1440p and in ray-traced titles. It’s going to be the first RDNA 2 graphics card with a VRAM capacity of less than 12GB. The RX 6800/6900 series comes with 16GB of GDDR6 memory while the RX 6700 XT packs 12GB.
In addition to this, it’ll feature a puny 128-bit bus along with an Infinity Cache (L3) size of just 32MB paired with 8GB of GDDR6 memory. As such, this card will be almost exclusively aimed at 1080p gaming. Both the RTX 3060 and 3060 Ti feature a much wider 256-bit bus, making them much more capable at 1440p in comparison. In terms of compute, the 6600 XT is powered by 32 Compute Units or 16 Work Group Processors resulting in 2,048 stream processors (cores).
As for the Radeon RX 6600, it is going to be based on a cut-down Navi 23 die with 28 Compute Units (14 WGPs) or 1,792 stream processors. The memory sub-system is going to be the same as the XT variant. It is expected to be priced at $299, with raster performance somewhat lower than the $329 RTX 3060 [Source].
For comparison, the RTX 3060 and 3060 Ti come with 12GB and 8GB of GDDR6 memory, respectively paired with a 192-bit|256-bit bus. The former features an FP32 core count of 3,584 while the latter increases that figure to 4,864. The 3060 Ti also features more RT (38 vs 28) and Tensor cores (112 vs 154) as it’s based on the GA104 die (same as the 3070), while the 3060 leverages the GA106 die.
