Here are some real numbers and datasheets from the raspberry pi foundation>> https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/
Cpu gets overall performance score about 50% more than previous generation. Linpack test measures only floating point unit.
Cpu is 64-bit arm v8. But why gpu is 32 bit?? Same as pevious model(not sure how is that meaningful)
Hevc and h264 decode - great. H264 only 1080@60fps - not sure if that equals to 4k@25fps yet.
USB 3.0 - great.
HDMI 2.0 >> Native 4:2:0 and 10-bit/HDR transmission (ITU-R BT.2020)
GPU opengles 3.0 only....but 100 Mgz faster and much more bandwidth
RAM 4GB - great
the rest of specification is improved too but out of my interest.
Overall great move, but 4GB model costs almost 50% higher. More ram would be needed in graphic tasks and fluid 4k movie decoding.
Plenty of benchmarks showing CPU performance gains well above 50% it depends on the task.
Spoiler: (Show Spoiler)
But also some showing closer to 50%

It really depends on the load but It's running a much more efficient processor so looking at it from the perspective of it "only" being .1ghz increase seems strange to me.
