GeForce GTX 480M

25 05 2010

This popped today.  Some of the coverage is negative, folks are disappointed over clock speeds and the fact that this new part is based off the desktop GTX 465 – not the GTX 480.

I say who cares? It’s not hard to see how this will compare very nicely to the Mobility RADEON 5870 (itself based on the desktop 5770). One of these could be almost 3x the performance of the 280M (352 cores versus 128 cores) and the use of GDDR5 gives its memory an effective speed of 4,800 MHz with data carried on a nice wide 256 bit bus!

CUDA Cores: 352
Gigaflops: 897
Processor Clock (MHz): 850 MHz
Texture Fill Rate (billion/sec): 18.7
Memory Clock (MHz): 1200
Memory Interface Width: 256-bit
Memory Bandwidth (GB/sec): 76.8
I’d like to see two of these paired with an i7. Next gen M17x anyone?




What Did Five Months With an Alienware Teach Me?

24 04 2010

In late November I traded my 2009 15” MacBook Pro for an Alienware M17x. I did a few articles on the M17x, here, here and here. The Apple and Alienware notebooks were polar opposites of each other. The MacBook Pro was a highly portable productivity tool with excellent battery stamina. The Alienware was a super high performance gaming rig, big and strong and designed to survive trips to LAN parties.

M17x: Quad Core versus Dual Core

27 03 2010

One unanswered Alienware M17x question that I have is ‘what is the true benefit of extra CPU cores to a gaming system?’ Common sense dictates that more CPU cores should be better, but often mobile Quad Core CPUs operate at slower speeds than their Dual Core counterparts.

To answer this question I obtained an Intel Q9200 ES CPU from eBay. Read the rest of this entry »





Mobility RADEON 4870 Crossfire versus Nvidia Geforce 280m SLI

6 03 2010

I had a brief time with both Nvidia 280m SLI and AMD Mobility RADEON 4870 Crossfire setups for my Alienware M17x notebook. This seemed like a good opportunity to test the competing video systems on the exact same platform.

Between switching from Nvidia to AMD GPUs I reinstalled the factory OS image, in this case Windows Vista x64 SP2. Here are the specifications:

  • CPU: Intel Core 2 Duo T9600 (2.8 GHz, 6 MB Level 2 Cache)
  • RAM: 4 GB DDR3 (1066 MHz rated for up to 1222 MHz)
  • Chipset: Nvidia aka 9400m G (Nforce 730i)
  • GPU:
    • Two Nvidia Geforce 280m 1024 MB GTX in SLI
    • Two AMD RADEON Mobility HD 4870 1024 MB in Crossfire
  • HDD: Two 500 GB 7200 rpm HDDs in RAID 0

Mobility RADEON 4870 Crossfire Test

1 03 2010

Dell has sent me a pair of 4870s to see if that fixes my M17x latency issues in Windows 7. This will give me a good opportunity to test the cards out and compare them to the notebook’s current Nvidia 280m SLI.

My gut feeling is that they will be very close.





Review: Alienware M17x All Powerful

16 12 2009

Reviewing this notebook was tough. Initially I could not get it to run games without crashing – often blue screening. I stumbled on the solution by way of a BIOS setting that I must have changed while tinkering.

Since then, the notebook has operated reliably and that made it hard for me to pull myself away from gaming. My enthusiasm for this notebook has grown to the point now where I feel like telling the world about it – or all 100 or so people who visit my blog each day LOL.





Alienware M17x Update – Yikes

7 12 2009

‘All Powerfull’ is the promise but the reality is ‘All Broken.’

As I work on my review of the M17x, my first challenge is to get it to a usable state. This has proven to be tougher than any computer I have ever owned. Some of the issues (and links to lengthy discussions of the symptoms and possible causes):

  1. Delayed Procedure Call Latency. This is an issue manifested by stuttering audio playback most frequently in music playback, but sometime games and movies.
  2. In game stuttering whereby high frame rates occasionally drop into single digits.
  3. Unexplainable crashes here, here and here.

In a week I have only had a single day of trouble free computing. Grrr! Time to call Dell I think.





Coming Soon: Alienware m17x Review

30 11 2009

OMG – I traded my MacBook Pro for an Alienware! What the heck was I thinking!

Might as well review it as I wait for regret to sink in.
