The three core processors phenom 8400 (2.1 GHz) and Phenom 8600 (2.3 GHz) will appear in the composition of finished computers during March, and retail users have to wait to the passage of these processors on B3 stepping . From one side, this is good news, since B3 stepping processors do not suffer from TLB problem. From other side, the delay of those processors appearance distresses potential buyers.
AMD company confirmed the beginning of deliveries of phenom 8xxx processors with three cores for OEM- market. We already met the three core processors phenom in composition of dell and HP computers.
HP computers with three core processor and 2.3 GHz frequency is called Phenom 8600B - In business- segment AMD proposes processors with increased life cycle, which obtain the suffix B. Associates already calculated the tentative retail prices of three core processors:
- Phenom 8750 (2.4 GHz) - > 170-175 Euro- (maybe more than $200);
- Phenom 8600/8650 (2.3 GHz) - > 150-156 Euro- (up to $179 );
- Phenom 8400/8450 (2.1 GHz) - > 135-138 Euro- (up to $159).
It is completely possible that during April these prices will be lowered, although the price ranges of three- and four core phenom models can overlap .
Associate reports that the TDP level for all three models does not exceed 89 W. This is less than analogous up-to-date four core processors phenom 9xxx (95 W). In tasks for processing multimedia content or rendering average performance increase upon transfer from two cores to three is equal to 30%, supplemental 20% are obtained after transfer to four cores. In other tasks, the increase in speed can be modest.
In retail network phenom processors 8x50 B3 stepping will appear not earlier than April- May, since all reserves of B2 stepping processors will be directed to OEM- segment, but processors on new stepping will be supplied only in retail. In turn, the three core processors B3 stepping will appear in retail only in April- May.
To partially compensate the release delay of phenom processors , AMD will release new dual cores processors (brisbane). For example, athlon 64 X2 5800+ (3.0 GHz) with 2 X 512 KB cache in the second level and TDP level not more than 65 W.
