well, base on the main page of lowyat.net. it seems that the 12MB of cache help to elevate the performance. i believe, the 40% increase is mainly due to the additional 2-core, and it is only for multi threaded application. correct me if im wrong.

it stated 4cores in side the proc.. penryn quad? price sure > than current core2quad..

more core mean nothing if software not created for multi core..

yup.. agreed, there still some program still wont ultilize pentium D and core2duo.. new 1 so fast come out, software programmers also need time to learn right lol

The extra boost came from the switch from 60 nanometers to 45nm and by using "high-k metal gate" transistors

Got nothing to do with cache, extra cores

40% faster in certain situations. You can bet that the 40% figure is pretty much a best case scenario. Much of it is also due to the higher clockspeeds.

40% increment only in those area that it has tweaked compared to C2Q, such as stream FP softwares.

i heard that Penryn provide more than 3ghz stock clock speed, with larger cache (6mb for dual core, 12mb for quad core) as well as 1600 mhz bus speed

current core 2 quad is fake

this one will be the real one, lets see how it will do against out longly waited agena

Hi-k affects leakage; it's the minor tweaks to the core that boosts the performance.

Is there a difference between "fake" and "true" quad?
BTW the correct term is non-monolithic and monolithic.

Penryn is still a non-monolithic quad core (2x Core2 Duo in the same package).

Actual (according to intel) performance numbers down the page:

Anand ran some benchmarks in Beijing, looks like Penryn isn't just die shrink with minor tweaks. Can't wait for the final review of the retail shipping cpu.

It is a minor tweaked core compared to Kentsfield. It shines only in FP and stream related applications. The other might have very little performance boost only, especially on applications which do a lot of context switchings and branches. The new power management isn't that good too as compared with Barcelona. However, it should can put up a good fight with Barcelona.

what the...f, even penryn got some numbers for us to see. but where is Barcelona numbers?

I've seen some pretty interesting power management stuff on Nehalem...

Yea, that is Nehalem, but not Penryn.
Nehalem took a step further than Barcelona in voltage management, but I can't disclose too much here thou

more info here.

looks like it will be a serious contender for K10, IF ONLY K10 perform what AMD claim now.

In fact there is: True Quad doesnt share the cache

Clock for clock? no. That only helps with power/leakage/frequency scaling.


No. Quad core means 4 cores. Does it have 4 cores? Yes it does.

By your definition, the barcelona is not a true quad core either because it has shared cache. lol.
