anyone using CUDA applications with the M6400

just wondering as im going to get this laptop if it runs cuda apps and there is a noteable difference in things like video transcoding with the likes of badaboom

just want to hear some personal experience from owners on here

 

All G80 and newer GPU chip support DirectX10, PhysX, OpenGL GPU programming, and CUDA. Your GPU is newer than the G80 chip.

I don't have the laptop so I can't say about the performance.

 

cheers for that i knew it was in the supported range just eager to find out some real life thoughts on its speed improvements

 

None of the CUDA drivers that I tried from NVIDIA works with my RGBLED screen. Once I installed the driver, I see everything as if there were a white filter in front of the display. Hopefully, other people had better luck.

 

I don't think you know or understand what CUDA is. :/

Your problem sounds like it's the screen image quality rather than the video card. Using Nvidia Control Panel, you TRY and adjust the colors, but don't expect a miracle.

LCD using a TN panel (most LCD screen) with a matte film are less vivid and have a lower-view angle than the glossy ones. Well in reality, matte film is the ordinary screen technology, but LCD manufacture had the brilliant of idea of instead of improving the screen technology, to cheap and provide a super glossy film instead of the matte one on the LCD. The result is the more glossy the film (screen) is, the more vivid the colors are and the greater the view angle, as the plastic film doesn't distort the colors as much as a textured sheet of plastic.

The solution is to use PVA or IPS LCD panels (they also provide more colors, significantly more color accuracy, and vivid colors). However, these are VERY expensive, are not great for fast moving action movies (lower response time), and consume way more power than a TN LCD panel. Oh it's bulkier and heavier as well.

TN panels are 6-bit colors. The old CRT tubed monitors were 8-bit or more (depending on the model) colors. ISP are like CRT's most of them are 8-bit (8-bit being the minimum), and the PVA are 8, 10, 12, 16-bit, 24-bit panels is what I saw.

Here is a PVA panel.. see how much it costs:

even the RGBLED display is a TN display. its just a different form of backlighting.

he'll need calibration software to calibrate his screen, its a common issue with very high gamut displays.

glossy does not add to viewing angle, it increases the contrast ratio.

having said that, i have no idea what he meant by cuda drivers either lol. or "white filter".


even the dell stock drivers support CUDA AFAIK

 

I stand corrected. I never experience glossy screen.. so I can only base on what I was told. After looking further into it, you are 100% correct.

 

What I meant is that I tried drivers from the NVIDIA CUDA Zone, that is what I meant by CUDA driver.

OOOOHHHHHHHhhhh You are the CUDA developer section.
If you notice, the "CUDA drivers" are actually your normal video card drivers
You might ask "But I did not select my GPU", it's because Nvidia has 1 driver for all Geforce, and another driver for all Quadro's (1 to rule them all, type of thing).
The only important thing to select is the OS.

 

lol all this and still noone tried any cuda apps :S
