AMD Athlon™ (Carrizo)x4 845 Interrogation
You could call it a performance review, I guess...
There are times when you get a horrible itch you just can't scratch because you are out in public and the itch is somewhere you'd rather not be seen touching - and then there are times when a new computing product comes to market and you do something crazy like promise people a somewhat comprehensive performance evaluation for their pleasure...
Luckily for you, this is one of those latter times. Sadly, it is also the former, and I am scratching my itch. But you can't see me, can you? can you?
How are we going to estimate Zen's performance, you ask? And what is this about an x4 845 "interrogation?"
Glad you asked! The Athlon™ x4 845 is based off AMD's Excavator architecture, itself an evolution of Steamroller - both descedents of the utter performance failure that was the Bulldozer architecture. AMD has repeatedly stated that their Zen architecture will have 40% higher architecturally-derived IPC - which generally equates to 40% higher performance (but not always). Until now, we've not had a good estimate of Excavator's desktop performance, making AMD's statement somewhat vague, with scattered unaffiliated performance guesstimates for Zen falling anywhere from Nehalem to beyond Skylake - numerous generations of Intel's hardware and a VERY broad range of performance.
My own estimates had put Zen right in the neighborhood of Haswell. Sadly, I do not have any Haswell hardware currently available to me, so I used Sandy Bridge, of which I have two.
