it does not really matter, coz even new laptops needs to be re-pasted with new good quality thermal paste. Not that cheap boogers from manufacturer.

 

+1.

IGZO is not actually a panel type. It's a type of transistor used in a display's TFT backplane, which is what controls the display panel (whether that panel is TN, IPS, or even OLED). It uses Indium-Gallium-Zinc-Oxide as a semiconductor instead of Silicon.

Compared to amorphous Silicon (aSi) which is what is used in typical displays, IGZO transistors have a lot higher electron mobility, so their conductivity is just as good at a much smaller size (conductivity depends on electron mobility and mass. Higher electron mobility means less mass is required for the same conductivity). With its small size compared to aSi, IGZO is useful for high density displays where aSi TFTs would start to block a significant amount of the backlight, requiring more power to the backlight to compensate (increasing exponentially as the pixel density increases). With IGZO TFTs, not as much backlight is needed to get the display to a certain brightness. So all-in-all for current LCDs like IPS monitors, IGZO mostly translates into some power savings. However, IGZO can also operate more quickly than aSi which may be useful if OLED takes off and the refresh rate limitations of LCD are no longer applicable. Furthermore they can be made transparent, which again may be useful if OLED takes off, since OLEDs can be made transparent as well.

For current displays though? IGZO just means some power savings especially on mobile devices with ultra-dense displays. There is no difference in image quality, accuracy, or what have you, between aSi-TFT-driven IPS displays and IGZO-TFT-driven IPS displays.

Hi,
did you ever try to replace standard paste in both cpu and gpu ?
did you notice real difference?

Which type do you suggest for this generation of chips?

thanks

 

Unfortunately I did not (yet). I know many cases people have changed paste and achieved better results (longer time on stress test without throttling or no throttling at all).

TB/usb-c appeared on dell site.

For now TB available on 7510 in i5/i7 only (no Xeon)

7710 seems to have ALL i5/i7/Xeon with TB/usb-c available to order.

 

The thunderbolt3/USB-C option is now available!

EDIT: My bad, should have refreshed before posting.

If it helps Newegg has 64GB of DDR4 2666 non-ECC for $394 (vs $549 for 2133) which I think is compatible according to the owners guide below (but it lists it as 2667).

GPU question. Debating between the Quadro M3000m and M4000m, but on several reviews I see that the FirePro W7170m actually compares to the M4000m yet is priced lower than the M3000m.

Is there a certain negative against the firepro? It costs less yet performs better? Problems other than drivers?

Is the M4000m worth it over the M3000m, and/or is the M5000m really worth the $550 over the M4000m. Video editing (sony vegas/premier pro) AutoCAD, some gaming to be the biggest GPU impact programs. Not to much gaming, but if the M5000m is really that much better might be worth it.

Another note, is Pascal 'really' going to be that big of a performance increase over Maxwell. Made that mistake thinking typical 5-10% performance increase and got a 880m, then Maxwell came out and just smoked it. Want to make sure pascal wont be same impact Maxwell made.

 

I've never been a big fan of ATI's/AMD's OpenGL drivers; I always had compatibility and other issues... but that was a while back. I don't know if it's gotten better, and AMD cries still that the benchmarks used today favor NVidia. But AutoCAD I believe has moved on to DirectX so you should be fine. I also recall ATI/AMD cheating with their AF and AA to get better benchmark numbers, and still frame captures back when did detect graphics anomalies. Again, don't know if they resolved that either. I pay a little more and stay away.

All pointers lead to Pascal being much more faster than Maxwell, if simply for the use of HBM2, which has over 17 BILLION transisters, and 256GB/s memory throughput per memory stack. And since Pascal can handle 4 memory stacks that's 1TB/s memory throughput! Now all we need is Pascal with 32GB HBM2 memory and an 8K display on our notebook....

 

It appears they have taken away the TB3 option for all models now It was only an option for a few hours on Dell USA.

 

Can anyone with the FHD display tell me how the display is? Can any of you tell me how the sRGB coverage and brightness is like? In addition, can anyone tell me what the difference is between the UltraSharp FHD display and the normal FHD display? They provide the color gamut of the normal FHD display (which I assume is NTSC), but the don't provide that color gamut of the UltraSharp displays.

Finally, is there really a fan issue when using the gpu?
