AMD Phenom II X6 1090T on CPU-Z

CPU-Z 1.54 shows that the AMD Phenom II X6 1090T processor has 512KB L2 cache per core and 6MB shared L3 cache. This adds up to the entire processor having 9MB of cache (L2+L3) available to it, which is slightly more than the Core i7 quad-core processors as they have 8MB cache. The Intel 980X six-core processor has 12MB cache though, which trumps all desktop processors on the market today.  
The AMD Phenom II X6 1090T processor has an 16x multiplier with a 200MHz reference clock, but features low power states and turbo CORE mode. This means that the core clock frequency and base clock will rise up and down all by itself, depending on the workload. This is a brand new feature to AMD processors!  The screen shot above shows the AMD Phenom II X6 1090T processor at an idle state. You can see the multiplier dropped down to 4x and the core speed or overall clock frequency is just 800 MHz.

When the AMD Phenom II X6 1090T processor was running at full load the multiplier jumped up to 16 and the overall clock frequency is now 3.21GHz, as you can see from the screen shot above. This is what happens when a heavy load is on at least four or more threads. 

When the AMD Phenom II X6 1090T processor is under a light load on just three or fewer cores the multiplier jumps up to 18 for an overall clock frequency of 3.6GHz.  This is how AMD Turbo CORE technology works. It's not as complicated or efficient as Intel's Turbo method, but it works and is certainly better than not having it!
