Acer Aspire 4740G Review
Acer Aspire 4740G Review
There is 1 confirmed bug on the Acer Aspire 4740/4740G Insyde EFI Firmware.
Bug 2:
They didnt remap the memory properly resulting in not all 4GB fully utilised. By rights if they are not going to utilise Intel HD Graphics they should have allocated 0MB to the Intel Graphics DVMT(or let user decide by enabling the menu in EFI setup menu).
I got my hands on one of the newer Acer Laptop: Acer Aspire 4740G
This is a rather cheap laptop with rather good specifications.
I wont be posting any picture of this laptop as you can google how it looks yourself.
To me performance is a more vital information source.

Windows Experience Index
Note: The harddisk is a upgraded WD BEKT 7200RPM 16MB Buffer Drive the default 5K500 Hitachi Drive doesnt give as much performance
3D Mark 06 Scores
CPU
CPU
The New Arrandale CPU i330 M330 (the lowest end)
The Throttling States is as follows:
Lowest Frequency: 1200MHZ Multiplier: x9.0
(In between Multiplier changes from x9.0 to x16.0 depending on CPU Usage thus conserving power,however sometimes it hits x7.0 Multiplier could be a bug,
QPI is fixed and no more Front Side Bus)
Maximium Frequency: 2100MHZ Multiplier: x16.0
It is Physically a Dual Core CPU with 2 Hyperthreading Cores so 4 Logical Cores in Total
Graphics SubSystem
Note:
There maybe some errors regarding PhysX. Official Statement about PhysX is only 32 CUDA Cores GPUs are supported however G 310M only has 16 CUDA Cores. But I have tested AS4740G and it DOES support PhysX using the latest Nvidia 257.21 driver but I wouldnt count on the performance.
GPU is soldered to the board as VGA BIOS/Firmware cannot be read by GPUZ the normal way. Also Soldered GPUs can reduce the pricing of the laptop therefore this can explain the cheap price of Acer Aspire 4740G.
Below is a picture of the GPU and CPU
Note GPU is soldered onto the mainboard therefore NOT UPGRADEABLE.
CPU is a PGA Socket hence UPGRADEABLE.
Although the laptop has Intel HD Graphics onboard the CPU (see the 2 die above?), it is not activated or detected, you can pray that Acer will release a BIOS, no sorry EFI Firmware that will unlock Optimus or Switchable Graphics BUT from my past experience with Acer chances are as good as striking lottery...

Temperature Dissipation Test
This is a new Test I devised to measure how well the unit dissipate heat it can produce at maximium performance:
My opinion on this result is that this Acer Aspire 4740G handles heat pretty decently.
Considering that Acer uses Thermal pad on the GPU this is a very good result.
I estimate if the thermal pad is replaced by a Copper Shim temperature will fall by a good 10 degrees.
Only real Tests like the one I conducted can accurately determine if a particular model potentially has thermal issues, not old grandmother stories like how my Acer from 10 years ago overheat therefore all Acer overheat(This is a flawed argument by the way).
Anyway a computer that cannot dissipate the heat it produces is as good as a man who cant wipe his own backside (Acer Aspire 4530), so this laptop does pretty well.

Kombustor rate of temperature rise graph:
3 PowerMizer States are as shown below:
It seems to indicates a decent CUDA Device.
Power Consumption Max Load Mode (Using JouleMeter from Microsoft Research)
Power Consumption Idle Mode(JouleMeter from Microsoft Research)
So there you go all the information you need to consider this laptop for usage.
If you know how to reinstall an Operating System, always do a clean install for better performance.
Why, because if you go Windows Hardware Developer Central there is a report that stated over 80% of OEM Imaged Computers has lousier performance than a Clean Windows Installation.
I believe this is due to OEM Crap pre-installed in the computers.
Remember to run idle task and defragment the harddisk so AFTER installing all drivers to ensure optimal performance.
