Hey everyone! I'm currently using an RX 6700 XT and considering an upgrade to the RX 9060 XT before prices rise further here in Denmark. However, I'm a bit puzzled by the VRAM specifications. According to their Wiki pages, the VRAM stats for the 9060 XT are worse than those of my older 6700 XT. I've seen benchmarks showing that the 9060 XT performs better overall, but I'm trying to wrap my head around how it can have 16GB of VRAM while still having inferior specs (like a 128-bit bus and 320 GB/s bandwidth) compared to the 6700 XT, which has a 192-bit bus and 384 GB/s bandwidth. The 9060 XT does have a higher clock speed, but can someone explain how that and the new RDNA4 architecture make it more efficient despite the lesser bandwidth? Thanks in advance! 🙂

What specific stats are you worried about? Sometimes a zoomed-in focus on specs can lead to misunderstanding the whole picture.
It's really about architecture! Think of it this way: an older Intel chip running at 3.5 GHz might seem powerful, but a newer chip at the same speed can outperform it due to better design, newer manufacturing processes, and software optimizations. The 9060 XT is designed to be more efficient even with less VRAM, and its advantages go beyond specs, incorporating improved driver and app compatibility too.
You're focusing a bit too much on just the VRAM stats. Remember, VRAM speed and bandwidth are only part of the equation when it comes to GPU performance. The RX 9060 XT is two generations newer and features more powerful stream processors, which help offset the lower bandwidth. In general, it's about 25% faster than the 6700 XT, so those newer capabilities are substantial.
I was talking about the VRAM stats, like bus width, bandwidth, and memory size. To clarify: my 6700 XT has a 192-bit bus and 384 GB/s bandwidth while the 9060 XT has a 128-bit bus and 320 GB/s bandwidth. The only edge for the 9060 XT seems to be its clock speed, which is 20.1 GB/s compared to the 6700 XT's 16 GB/s. I just thought that couldn't compensate for the other differences!
