AMD Radeon On Linux 6.13 + Mesa 25.0-devel vs. NVIDIA R565 Linux Graphics/Gaming Performance

Ahead of the upcoming NVIDIA GeForce RTX 50 series graphics "Blackwell" and the AMD Radeon RX 9070 series "RDNA4" later in the quarter, I figured it would be worthwhile having a dedicated article looking at the latest upstream Linux graphics/gaming performance for current generation NVIDIA GeForce RTX 40 and AMD Radeon RX 7000 series graphics cards. On the AMD side was the near-final Linux 6.13 kernel along with Mesa 25.0-devel for the latest RADV Vulkan and RadeonSI OpenGL driver support while on the NVIDIA side was their current 565 driver release branch.
