How bad was AMD Bulldozer and its variants
Like for 1 core of it on a clock per clock basis at the same speed.
Say one core of an AMD FX CPU at 4GHz vs an Intel Core i5 Sandy Bridge 2500K at 4GHz with no turbo or throttling.
Wasn'y Bulldozr so bad that at the same clock speed of 4GHz, it was way under even half the performance of even Sandy Bridge for a single threaded app or a multi-threaded app running on an Intel Sandy Bridge E using 8 cores at same exact clock speed?
Or was it not that bad but more like half or only 60% as fast?
