What is your point? RTX 2070 is far beyond Vega 64, with nearly comparable fillrate.
Your claim is still incorrect, Vega 64 is not ROP limited, nor is it bandwidth or Gflop limited.
GCN's problem is saturation of resources, which is why it struggles more on lower resolutions than higher.
Don't mix in compression, that's not relevant for this.
Wrong, If AMD is promoting async compute which uses TMU as read/write units, then there is ROPS bound issues.
GCN's problem is saturation of resources, which is why it struggles more on lower resolutions than higher.
This is not correct, lower resolution with high frame rates requires lowest latency and highest narrow parallelism performance .
NVIDIA's higher clock speed leads to lower latency with the workload loop
At higher resolution, there's a higher chance for very wide parallelism workloads which has higher benefits for AMD's lower clock speed GCNs.
GCN so far are Geometry bound, GCN has been stuck on 4 Geometry Engines since Hawaii / 290X.
Vega was suppose to have new features to by-pass that limit, but RTG never managed to get it to work, so it ended up just being a higher clocked Fiji.
One of the reasons why Polaris performs as well as Hawaii with half the ROP etc, it is still limited to 4 Geometry Engines (other optimizations aside), which is much less of an issue on a mid-range GPU vs a high-end.
Raja Koduri joined AMD in 2013 and under Koduri administration, RTG has focused on TFLOPS increase without increasing quad raster engine unit count.
Hawaii doesn't have Polaris delta color compression improvements.
Hawaii doesn't have Polaris 2MB L2 cache improvements. Hawaii has 1MB L2 cache for it's TMUs.
It's most likely VII is stuck in quad raster engine unit count.
