It's not exactly the same, no.
i) New one is two millimeters wider, but with 17 less fins overall. All other specs identical.
ii) New one has different heatsinks, so as to accommodate for (most by now) conteporary products' VRM placement. I'd remind that for many recent cards, the older model's VRM heatsink was useless.
?) New one appears to have a slightly larger contact area, which would make sense and would be welcome; could be a Photoshop thing though, to be seen.
My take? Barring any improvement in the contact area?
If there's a performance difference between the two, you probably wouldn't know even if you tested it.
If there's an accoustic difference between the two, you probably wouldn't notice until a "reviewer" told you there was.
If you have or use your own custom heatsinks (or buy good ones externally), zero upgrade from the old one.
Now if they did
change the contact area.. sadly we wouldn't know. Because you all wanted ""noise"" "normalised" testing. And by now you've got it
