Santa Rosa and Penryn = ?

I've been confused about this for a while now. I know they, i.e. Santa Rosa and Penryn are both Intel processor classes. But are they the same thing ? What's the difference ? They're both notebook CPUs, right ?

 

Penryn is over 233 times the size of Santa Rosa.
population wise.

 

so..... I know the Sager NP5793 has the Penryn. And which is better among the two ? And now what the heck is Centrino ?

 

Santa Rosa is not a processor class but refers to the centrino platform consisting of 965 series chipset, 3945/4965 wifi adapters & the socket P 65nm Meroms & now the new 45nm Penryns processors. The X3100 integrated GPU was also introduced along with the platform.

The main difference between merom and Penryn is that the penyn's are manufactured on a smaller manufacturing process and so should provide better yields for intel and improved power consumption and reduced heat output for the consumers. Ofcourse Intel did raise the clocks a bit and changed the cache capacity being offered(3MB & 6MB) on the regular C2D models. Basically Penryns are just an update to the existing merom series. Intel should release updates to the Santa rosa platform in the coming months and expectedly penryns should also receive an update around that time.

 

Okay so right now, Penryn > Santa Rosa. That answers that. Thank you!

 

Penryn is a part of Santa Rosa(codename for the current generation centrino platform).

Penryn > Merom

Montevina(not yet released) > Santa Rosa.

Hopefully that clears up any confusion.

 

Santa Rosa is not a cpu. It's a platform for the penryn and merom cpus. So you can't compare a cpu vs it's platform and say which is better, cuz you're not comparing the same thing.

So penryn is the new cpu replacing merom on the Santa Rosa platform. Centrino is just a name for any laptop that has an intel cpu, intel chipset and intel wifi.

 

adinu and miner are right!

 

but how does it compare to t 7500 or t7300?

much faster or just a bit ?

if it is much faster , I will buy DV2700 with T8300 but ,other wise ,I will get it with t7500 since the T7500 model is 250US cheaper than the T8300 based model here in Thailand.

 

How does Penryn compare to a T7500 or T7300? Well, that depends on what Penryn processor you are talking about.

According to wPrime32 results (CPU benchmarking program) the Penryn T9300 2.5Ghz 6MB L2 Cache is 20% faster than the T7500 2.2Ghz 4MB L2 Cache and 25% faster than the T7300 2.0 Ghz 4MB L2 Cache.

The T8300 2.4Ghz 3MB L2 Cache is faster than the T7500 but I haven't seen a wPrime32 result for the T8300 so I can't tell you by how much. (probably less than 10%)

For 250 USD I wouldn't recommend getting the T8300 over the T7500. Unless battery life is of paramount importance in which case the T8300 will give you 10% longer battery life.

Hope that helps.

 

It will definaltely be a bit faster but not worth paying the $250 premium IMO. Check ut this review for some benchmarks comparing equivalent clock speed Merom & Penryn...

Thanks guys!
