AMD Phenom is back with not 1, not 2, not 3, but 7 fresh from the oven models. The infamous TLB bug gone, and the B3s are renamed as 9x50. In this extract of the article from Anandtech, we shall see how they perform against Intel's offerings as well as their B2 siblings.
| Cores | Stepping | Clock Speed | TDP | L2 Cache | L3 Cache | 1 Ku Price | |
| AMD Phenom X4 9850 | 4 | B3 | 2.5GHz | 125W | 2MB | 2MB | $235 |
| AMD Phenom X4 9750 | 4 | B3 | 2.4GHz | 125W | 2MB | 2MB | $215 |
| AMD Phenom X4 9750* | 4 | B3 | 2.4GHz | 95W | 2MB | 2MB | $??? |
| AMD Phenom X4 9650* | 4 | B3 | 2.3GHz | 95W | 2MB | 2MB | $??? |
| AMD Phenom X4 9550 | 4 | B3 | 2.2GHz | 95W | 2MB | 2MB | $195 |
| AMD Phenom X4 9100e* | 4 | B2 | 1.8GHz | 65W | 2MB | 2MB | ~$200 |
| AMD Phenom X3 8600* | 3 | B2 | 2.3GHz | 95W | 1.5MB | 2MB | ~$175 |
| AMD Phenom X3 8400* | 3 | B2 | 2.1GHz | 95W | 1.5MB | 2MB | ~$150 |
*OEM only
Phenom X4 9850
The 9850, being the top of the line B3 Phenoms, is a "Black Edition" part, meaning it has an unlocked multiplier. It is also the first AMD processor to have its L3/Northbridge/Memory Controller running at 2.0Ghz.
Overclocking:
Overclocking wise, it was slightly better than any previous attempts, it managed to stabilize @ 2.8Ghz with a voltage boost.
Performance Impact of the TLB Bug
| SYSMark 2007 | DivX | CineBench R10 | 3dsmax 9 | WinRAR | |
| AMD Phenom 9600 (B2 Stepping) - TLB Fix Disabled | 117 | 74.3 fps | 7396 | 7.20 | 1348 KB/s |
| AMD Phenom 9600 (B2 Stepping) - TLB Fix Enabled | 105 | 72.0 fps | 7031 | 6.47 | 367 KB/s |
| Performance Impact | -10.3% | -3.1% | -4.9% | -10.1% | -72.8% |
As you can see, there are loss in performance in all areas. Running Winrar with the TBL fix enabled is as good as disabling 3 out of the 4 cores.
