Intel i7-3920xm

[MonnieRock]

Hello Everyone,

 

What are your opinions on a Intel i7-3920xm running at 4.5ghz? Enough for DCS?

 

Thank you,

Monnie

[Pyroflash]

Probably. I would say that it should have similar performance to the desktop Sandies. Probably a bit less, but it should be okay for DCS.

[EtherealN]

Should work fine, but I wonder how you're going to scare that one up to 4.5GHz? The chip itself will probably do it, but it's an OEM-only chip, and I'm not sure how many laptop makers will support that level of OCing - and of course offer the required cooling (Ivys run hotter than sandies).

[MonnieRock]

EtherealN,

 

The laptop I am looking at provides a different heatsink for the XM processors to give extra cooling(three heat pipes instead of one). Also, they enable options in the BIOS to modify the settings to overclock the processors. Intel XTU application can also be used on the XM processors to change a few things too but, not total control over the settings. Combined with both of those the processors can be overclocked quite a bit. Some are getting 4.9ghz on the i7-2960XM

 

Being DCS runs off of two threads, the other cores will not be taxed that much so overclocking two of the used cores should provide a healthy gain in performance without too much heat.

 

Intel plans to release a i7-3940xm that will be 3.0ghz and 3.9ghz turbo

 

There are rumors for a i7-3960XM that will be 3.3ghz and 3.9ghz turbo

 

The laptop will be configured with nVidia GTX 680m SLI

 

Thank you,

Monnie

The problem is really that if you overclock to a setting that works in DCS, but might not work in something that uses all cores fully, you are liable to have unpredictable performance.

 

Still sounds like a neat machine, got a link to the retailer? Might considering it for myself if they ship internationally.

Yeah, same here, I am looking for a new laptop, but the new ASUS one just didn't live up to my expectations.

the 3940xm seems to be true, however there will NOT be a 3960xm. if you type in 3960xm and search on google, it'll probably show up something like 6 cores 3.3ghz in a SAGERs laptop. and do know that these flagship sagers laptop uses DESKTOP CPU so they are NOT 3960XM in fact its actually 3960X.

 

and yes, those guys who said they are 3960xm are wrong and not knowing much or made a mistake just because a desktop processor in a laptop doesnt mean CPU has changed from a X to XM.

ah yeah, this being a laptop I wouldn't count on such high overclock... I don't know... maybe there are people that have done but I wouldn't know about it since I don't follow laptops at all and how they fare with our flight sim gaming

that is not necessary true, but if you dont follow laptops then it makes sense. the technologies nowadays in laptop is amazing. last year's sandy bridge mobile extreme processor 2.7ghz, i7 2960xm is proven and able to OC to 4.5ghz on all 4 cores/8 threads on 24/7 with stable temperature. there are many who are able to push to 4.8-5.0 but results in BSOD as well as throttle/shutdown etc, but all in all 4.5ghz is the stable speed and think about that speed at 24 hrs/day 7 days/week at acceptable temperature. and heck, it sure beats the desktop extreme processor i7 3960x a stock speed hands down.

 

anyway, anyone know the release date of this 3940xm? probably will get myself an alienware m18xr2 when this is released, along with 680m SLi (equivalent to desktop GTX 670 SLi but clocked lower)

Gentleman,

 

Thank you for the input. :thumbup:

 

EtherealN and Pyroflash, the machine I was looking at that enables overclocking as well as excellent cooling is the Alienware M18x R2. There are several retailers besides Dell/Alienware that ship internationally.

unityole,

 

This was my plan too. :thumbup:

so apparently this refresh will take place during sept to november this year, and that seem to be when Sandy E 3980x will be coming out, late this year. depending on if 3980x will have 8 cores 16 threads, i might end up going for a sagers laptop.

You don't want an eight core proc, and giving it 16 threads is only going to make the problem worse. There is almost nothing you can run in a home user environment that will make use of a full eight cores, and it will only hinder your performance under normal applications such as DCS. The current Sandy-E I7-3820 is more than enough processor.

i encode and process video in HD for about 6-8 hrs a day, surely i would take on the multi threaded CPU. oh and trust me i know that stuff, since i am using 2960xm at 4.1ghz on all 8 threads at the moment and i only wish it could go faster. (reason i dont run it on 4.5ghz like how i posted b4?, cause im a pussy and dont wanna risk my CPU, and i suck at overclocking)

 

this also includes 3D and CAD rendering for my university work as well, and brag rights.

 

speaking of which, 3940xm is out on notebookcheck.pl release date is said to be OCT 1st.. kind of late, could probably just wait for Sandy E, or IVY E, or haswell mobile extreme cpu..

Hello Everyone,

 

I ordered the Alienware M18xR2 with the Intel i7-3920XM and nVidia GTX680m SLI. Once I get it, I will report back how well DCS A10C runs on it.

 

I ordered some additional hardware to abduct my new Alien once it lands.

2 of these for RAID0 OCZ 256GB Vertex 4

2 of these for a total of 32GB Kingston HyperX 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 Laptop Memory HyperX Plug n Play CL9

1 of these which I have not decided to use as a onboard recovery/backup or run Windows on it becuase it is only SATA2 Mushkin Enhanced Atlas Series mSATA 60GB SATA III MLC Internal Solid State Drive

1 of these Sony Optiarc Black 6X BD-R 2X BD-RE 8X DVD+R 5X DVD-RAM 6X BD-ROM 5.8MB Cache SATA 12.7mm Slot Blu-ray Writer BD-5850H-01

1 of these Thrustmaster HOTAS Warthog

 

Thank you,

Monnie

Laptops dont make good gaming rigs generally speaking. Several reported problems.

Update,

 

Just waiting on China to make more GTX680m GPU's. They use the same core(1344 cuda cores) as the GTX 670 desktop and they are selling like hotcakes. TSMC is not ramping up production

 

Estimated delivery date is Sept.12th

Hello Everyone,

 

She landed in pristine condition at home base Wednesday 08/29/2012. Loaded up US DVD 1109 for a test, ran extremely smooth. Off the next 7 days so I will get DCS world & 1.2.0 installed to report back.
