Why 2200+ & 2800+ in both model 8 & model 10 Sempron?
Reality wrote:
There is 1500 (2200+) and a 2000 (2800+) in the Sempron model 8 range. There is 1500 (2200+) and a 2000 (2800+) in the Sempron model 10 range. In these two AMD publications on page 21 (as numbered by AMD) of each document they show a pair of 1500 (2200+) and a 2000 (2800+) models. AMD Sempron Processor Model 8 Data Sheet http://www.amd.com/us- en/assets/content_type/white_papers_and_tech_docs/31693.pdf AMD Athlon Model 10 Processor with 256K L2 Cache Data Sheet http://www.amd.com/us- en/assets/content_type/white_papers_and_tech_docs/31994.pdf Why is this? AFAIK both the model 8 and the model 10 Semprons are Socket A, 333 FSB with 256K L2 cache. Correct. The Athlon model 8 (TBred) is manufacturered with only 256KB of L2 cache (how much a Sempron has). The Model 10 Athlon (Barton) is manufactured with 512KB of L2 cache. These require more silicon so are more expensive to manufacture. The Bartons that pass all the QC checks become the high-end Athlon XPs, and the ones that pass all of them but have half the L2 cache faulty get half their L2 disabled and used as 256KB Athlon XPs (sorry, Semprons). Basically: [] Model 8 Sempron = TBred [] Model 10 Sempron = Barton with half the L2 cache disabled (no, it's not possible to re-enable it any more) If you want to actually get a Sempron (not recommended) you want the Model 10's, because they overclock a bit better. The Socket 754 Sempron is an Athlon64 (Newcastle?) with half the cache and 64-bit extensions disabled. It's a completely different beast to the Socket-A Semprons, which are just Athlon XPs with a different name and a higher model number (and hence a higher price). -- Michael Brown www.emboss.co.nz : OOS/RSI software and more Add michael@ to emboss.co.nz - My inbox is always open |

It's a completely different beast to the Socket-A Semprons, which are just Athlon XPs with a different name and a higher model number (and hence a higher price). reading a bit more web stuff, i see: sock a is k7 sock 754 is k8 http://anandtech.com/cpuchipsets/sho...px?i=2139&p=14 jul 04 [july info is a bit old, i guess] [seems Sempron 3100+ is still the only semp k8] Socket A Sempron will eventually be targeted at the extreme budget line of computing with the Sempron 2200+ clocked at 1.5GHz and priced about where we can find 1.2GHz Duron processors... looking forward to testing some extreme budget systems based on these processors. [looks like retail k7 semps are mostly 2800+ already. 2200 is gone? 2400 going.] |

Is it possible that they just started calling some Athlons by the new name? The ID says it is a model 8 - the price was right, but it runs hotter than expected for a 'new' model chip. |
