athlon64 VS sempron64 (soc.754)

lep pozdrav!

mene pa zanima kaka je razlika med tema dvema procesorjema, saj sta oba namreč 64 bitna, cena pa je mislim da zelo različna?

semproni majo mn predpomnilnika.

128kB oz 256kB vs. 512kB.

Če bi prodajali 939 semprone bi bila razlika veliko manjša. Semproni na osnovi K8 (socket 754) jedra so hitrejši in hladnejši kot semproni na osnovi K7 jedra (socket 462). Torej sta dve vrsti sempronov.

Pri AMDjih je velikost predpomnilnika manj pomembna kot pri Intlu.

Pozna se tudi da plošče z 754 socketom nimajo dvokanalne komunikacije z pomnilnikom.

Tukaj je en test 64 bitnih sempronov Palermo (E6).
Sicer se pa lepo navijajo, tudi do 2500 - 2700 MHz, ne grejejo se in so zelo poceni

Ce bos kupoval, glej da vzames takega z 256 L2 cache-a, mislim da sta to 2800 in 3100.

Tvoj CPU je vsekakor hitrejsi kot sempron 3100. Vendar pa so Semprononi 64bit narejeni z novejso tehnologijo 90 nm, medtem ko je tvoj Newcastle narejen z 130 nm. To pomeni, da se semproni boljse navijajo in manj grejejo.
Newcastle cipi pa naj bi se navijali tam do 2.4-2.5 MHz.

As far as overclocking is concerned, neither the Newcastle nor Clawhammer cores do very well, though the Newcastle tends to be a bit better. 2.5 GHz is typically the maximum speed that they'll run, and many of them won't handle more than about 2.4 GHz. If you want to try overclocking, your best bet is probably the Newcastle 3200+, which is relatively inexpensive and can often reach nearly the same performance level as the 3700+. Motherboard choice will also play a role in overclocking, with the DFI LANParty UT 250Gb being the star of the platform. If you already have a socket 754 motherboard, however, we'd recommend that you stick with that rather than buying the DFI simply for overclocking - you'll have better luck with the 90nm 939 parts if overclocking is what you're after. The 90nm Palermo Sempron chips seem to overclock quite well - 2.5 GHz and above can usually be reached - but the reduced cache sizes bring diminishing returns. Coupled with the need for decent RAM or the use of an asynchronous memory bus, the benefits of overclocking Sempron chips are pretty slim. In the end, a 2.5 GHz 256K Sempron will roughly match a 2.2 GHz 512K Athlon 64 on socket 754.
