So, what does the listing tell us? Let's have a look...
Starting with the specifications, the database entry lists the Core i7-10700KF as having 8 cores and 16 threads with a 4GHz base clock and 5.3GHz max boost clock, and 16MB of L3 cache. It also indicates a 250W power draw. Are any of those specifications actually accurate, though?
Well, past leaks have also pegged the Core i7-10700KF as being an 8-core/16-thread processor with 16MB of L3 cache, though that is where the similarities end. Prior leaks suggest the Core i7-10700KF has a 3.8GHz base clock and 5.1GHz max boost clock, and a 125W TDP.
It's possible SANDRA is misreading the chip. Likewise, this is likely an engineering sample (assuming it's real in the first place), and depending on when it came out, the specifications could be different than what ends up shipping. There is also the possibility of overclocked settings.
What about performance? It's always tricking comparing SANDRA scores. However, Hardware Times pointed to an AMD Ryzen 7 3800X listing as a point of comparison. It has the same number of core and threads, with a 3.9GHz base clock and 4.5GHz boost clock.
In SANDRA, this particular entry posted a "performance vs. speed (aka speed efficiency)" cores of 65.78GOPs/GHz at 125W, versus 59.95GOPs/GHz for the Intel Core i7-10700KF at 250W (supposedly, anyway).
