Test of Sandy Bridge 2820QM CPU

Intel Core i7-2820QM Mobile Sandy Bridge Processor - HotHardware

So many good things about these SB CPUs. Really liked how freakin fast it was, how little watt it used when idling and in full load, how it performed against discrete GPU cards etc etc
Will be buying this or the 2720QM for shure.

An ULV version of SB Dual core I7-2649 with a cold cold TDP of 25W. It have base frequenzy of 2.3 GHz and turbo boost up to 3.2 GHz. Cheers

 

Also no SATA 3.0

 

not suprising since intel likes light peak which IMO will nver work for the next 10 years... Still , idk.. USB2.0 is enough for me now.

Panther214

 

They included it in their desktop chipsets, but not in their laptop chipsets?
Whoever is responsible should be traced down and shot, really..

DAAMIT, Intel!

 

at least in the laptop market it doesnt matter so much -- they are all freelancing their own mobos already and soldering on aftermarket usb3/sata 600 chips is not likely to req q new engineer or anything

 

But it probably won't happen due to added costs and designing/compatibility slowdowns. Either that, or they'll seriously upcharge for it.

 

the only thing that would use the sata 3 rigt now is the crucial c300.

there is no other possibilities of use unless going the ssd route. Which by a lot of people is still too much money.

It makes no sense for them.

Aside that you have to make due with a lot of old stuff from the older chipset due to the time constraints, much of what we see today is what we saw in the arrandale chipset.

so yeah most of the ''needed'' features like USB3 or sata3 wont be saw integrated directly onto the chipset.

 

but buuuuut G3s from Intel and Sandforce-2000 is coming out soon. Shure forget about us hardcore buyers

 

Well, the Sandforce 2000 chip will give the G3 a beating.
G3:
Sequential Read: 250MB/s
Sequential Write:170MB/s
read IOPS: 50K
write IOPS:40K
Security: AES-128

Sandforce 2000:
Sequential Read: 500MB/s
Sequential Write:500MB/s
read IOPS: 60K
write IOPS:60K
Security: AES-256

-- Im holding out hope for a ces announcement for sf 2000 ssds .. just, it would be nice if at least enterprise class drives started rolling out the fabs

 

ooops i forgot that the G3s are only SATA 2. What i meant to write was C400 and SF-2000.
oh yes, i really hope some ssds will be announced at CES. Hopefully the new controllers
But anyways, what i like about Intel is their liability and support. Have posted one graph somewhere where it showed that Intel SSDs had much less drive failures than Curcial etc.

 

Are there even noticeable performance gains over SATA II speeds?

 

only if you can saturate the sata 2 interface.

the problem is are you going to notice it?

 

Unless you do mass large-file transfers, the most noticeable speeds are typically random R/W speeds - which don't even saturate SATA/150 speeds.
