Gateway AMD and Intel Laptops, a Platform Analysis

LCD Quality
Wrapping up testing with a look at the LCDs, it's important to note that these are different LCDs in the same chassis. Since these are budget laptops, it's very likely Gateway switches LCD sources as necessary; some of the NV52 series might have LG Philips displays, and some of the NV58 series might use AU Optronics LCDs. We would also be surprised if results were consistent across all LCDs, since budget offerings usually get budget LCDs that can fluctuate wildly even on the same production line.

The white levels are similar while the black levels clearly favor the AU Optronics panel, with the result being that the AU Optronics LCD has a 43% higher contrast ratio. In fact, the LG Philips panel has the lowest contrast ratio of the tested LCDs. It's not the end of the world, and we do like the fact that Gateway is using LED backlighting, but these LCDs do little to change our overall impression of what a laptop LCD panel can do. Color accuracy is average (yes, the laptops attain the same average Delta E, though the individual color scores were very different), and color gamut is only slightly better than other laptops. Again, notice that the AU Optronics panel has a better color gamut than the LG Philips panel.

It's nice to see some humor in these articles. Nice to change it up. Reminds me of reading Mark Minasi tech books, and how much easier occasional humor makes it for me to read tech info.IntelUser2000 - Wednesday, August 12, 2009 - link
Jarred, the 475MHz core clock on the GMA 4500 is wrong. That has been the clock speed for pre-launch platforms. The GM45's GMA 4500MHD runs at 533MHz. Minor mistake but still a mistake.HexiumVII - Wednesday, August 12, 2009 - link
Can anyone comment on the performance of Aero with comparing the G45 with the X3200? I had a tablet with an X3500 that was a bit clunky with Win7 Aero Beta. It got a little better with RC drivers, but still not as snappy as 2D mode or dedicated graphics.JarredWalton - Wednesday, August 12, 2009 - link
I didn't notice any issues with normal applications in Windows Vista, but I don't know about Win7 yet. I will try to find time to do a follow-up looking at Win7 performance, and from what I've heard it's overall better than Vista (Gary for instance has it running on a netbook and he's very happy, whereas he hated Vista on the same netbook). Intel's Win7 drivers are likely still a work in progress as well, but at least you can get regular IGP driver updates from Intel.JarredWalton - Wednesday, August 12, 2009 - link
All I know is that GPU-Z reported the GMA 4500MHD as 475MHz. I would guess that either the utility is wrong (possible), or Intel gives vendors some leeway in the GPU/chipset clocks (also possible). If you have another utility that will be more reliable for determining the Intel IGP clock, let me know.IntelUser2000 - Wednesday, August 12, 2009 - link
Just take a look at the datasheet, its that simple: http://www.intel.com/Assets/PDF/datasheet/320122.p...">http://www.intel.com/Assets/PDF/datasheet/320122.p...The GPU-Z utility is bad. It's nowhere near the CPU counterpart. That aside, Intel doesn't really give out reading the GPU clock easily, and the 475MHz was also what was used in the pre-launch(ie. beta) GM45 platforms.
I heard Everest is more accurate, but in terms of actually measuring, there probably isn't one that measures the Intel IGPs properly.

In reality, it isn't really measuring the clock.
