Cite for that? All I see are numbers with an Intel CPU model next to them. I don't see anything reporting the hardware configuration except for the one AMD system, which as noted is very significantly tweaked.
The model name with a number next to it is some sort of average (they don't say but I think it's geometric mean?) computed from all scores submitted from that particular model. It's not terribly useful because you have no idea how many of them are overclocked, by how much, the memory configs, etc. without reading through every entry and a lot of them are missing info anyway.
This 3950X result is definitely not faster than the top overclocked 9980XE, but it is faster than something like 3/4 of them. Given the base clocks of each I would expect the stock 3950X will end up at least slightly faster than the stock 9980XE though.
What could be a cite for this. PC builders worldwide like to build their computers and then benchmark them on geekbench. Naturally the top most benches will be the heavily tuned ones.
