Okay, just a quick disclaimer: everything that follows is just rumors, so don’t take it at face value. But it seems that the first details about NVIDIA’s upcoming graphics cards are starting to surface. According to reports, with the RTX 60 series,ray tracing and path tracing performance could be twice that of the RTX 50 series. However, gains in rasterization are expected to be more limited: up to 35% according to estimates, nonetheless.
RTX 60: First Specs Leaked!
RTX 6090: ~13% more SMs!
Broadly speaking, this series of cards is expected to utilize GPUs from the GR200 series. Of course, the hypothetical RTX 6090 would utilize the largest chip in the series, potentially the GR202. This chip would not be fully utilized, as is the case with many cards from the 90 series. However, this model could feature up to 13% more SMs than the RTX 5090. If the number of CUDA cores per SM remains unchanged, we would be looking at a chip containing 24,476CUDA cores compared to 21,760 for the current RTX 5090.
On the memory side, this card would use a configuration similar to that of the RTX 5090, namely: a 512-bit bus and a total of 32 GB of GDDR7. So nothing exceptional here. We can expect a slight gain in bandwidth thanks to faster memory.
RTX 6080 and RTX 6070: a wider memory bus!
As for the RTX 6080 and RTX 6070, while we don’t yet know the number of SMs contained in the supposed GR203 and GR205, speculation suggests a wider memory bus compared to that of the RTX 5080 and RTX 5070. Specifically, we’re looking at 320-bit and 256-bit buses, respectively. This 64-bit increase in width allows for gains in memory bandwidth. As for memory capacities, 20 GB of VRAM on the RTX 6080 and 16 GB of memory on the RTX 6070 are being mentioned.
Well, given the current state of the market, this is something we shouldn’t take at face value. We’ll have to wait and see if other rumors point in this direction or not.
Performance gains mainly due to the architecture!
Well, as you can see, given what the RTX 6090 is said to offer, we can’t expect performance improvements linked to a significant increase in the number of CUDA cores in these GPUs. We should mainly expect architectural gains and improved ray tracing units, and the same goes for the Tensor cores. We’re talking about 5th-generation RT Coresand6th-generation Tensor Cores .
Stay tuned—we’ll certainly have more updates in the coming days.
