Asus G1Sn Packing a nVidia 9500m GS at CES

The Asus G1Sn notebook is equipped with an NVIDIA GeForce 9500M GS mobile graphics processor. According to the system properties, the 9500M GS has a GPU code name of G84 and in this particular configuration, it is coupled to 512MB of frame buffer memory. Based on the naming convention, we would speculate that this is a mid-range mobile GPU - and we expect it to perform as such - but with features similar to that of the upcoming GeForce 9 series of graphics processors, there is a good chance that it might enjoy nVidia’s new Hybrid Power implementation when used with future nForce mobile chipsets.

nVidia Hybrid SLI - saving a little bit of battery power.

Now, I’m pretty sure both Sony and Asus have already created this (both called “hybrid graphics”), but apparently nVidia wants a piece of the pie with their somewhat-misleading “Hybrid SLI” moniker. Nevertheless, its a step in the right direction for laptop GPUs.

nVidia Hybrid SLI

GeForce Boost does what its name suggests. By coupling the motherboard’s integrated GPU with a discreet graphics card, the 3D rendering workload is shared between the two GPUs for a boost in performance. Currently, GeForce Boost is only supported by GeForce 8400 GS and 8500 GT discreet cards, as for the IGP, only the next-gen nForce 700a series of chipsets due to arrive this quarter will be supported initially. New IGPs for the Intel platform that support Hybrid SLI are slated to arrive in Q2.

Hybrid Power mode is also fairly self explanatory. With a monitor connected to the mGPU, the discreet graphics card can be completely shut down to reduce power consumption when no in use. A side effect of the reduced power consumption will also be reduced heat and potentially less noise output from the system. The discreet card is shutdown (or renabled) using the SMBUS connection inherent to the PCI Express graphics slots. We should also note, that Hybrid SLI is supporteb by both PCI Express Gen 1 and Gen2.

nVidia GeForce 9800 GX2 Graphics Card (9800gx2)

nVidia’s 8800 Ultra card is the fastest video card on the market, bar none. According to HardOCP, nVidia aims to raise the bar again in the spring with their next-gen card, the 9800 GX2. With a reputed speed boost of 30% and support for Quad-SLI, the 9800gx2 may be the card that puts the nail in ATI’s high-end coffin.Update: They say the expected price: around $449 US and the release date: February 14, 2008.

Sony Vaio SZ650 Premium Laptop Review

Sony Vaio SZ650 Review
Sony is well known for their excellent laptop design, dating back to before physical beauty was a selling point to potential laptop buyers. Models like Sony’s X505 (reviewed here) ultralight, the thinnest notebook ever commercially produced to this day, set the bar very high for other manufacturers. The sz650 continues this tradition, with physical beauty rivaled only by a select few (Apple, Acer and late model Dell XPS). The premium full-coverage carbon fiber body is thin and sleek. The LED-backlit 13.3’’ screen is a marvel, bright and razor thin. The laptop spares no features but maintains a very light 4lb total weight.

Hardware: The guts of the SZ650 are top of the line and no expense is spared to built one of the fastest ultraportables on the market. My SZ650n/c model came equip with a 2.2ghz Core 2 Duo t7500 processor, 2 video cards (an intel X3100 and a nVidia 8400GS), 4gb ddr2-667 RAM and a 160gb hybrid solid state/platter harddrive. Other amenities include a biometric fingerprint scanner, an integrated webcam and an expresscard slot (complete with multiformat card reader in the box). The screen is a marvel as well, a LED backlit panel that is even and bright. This impressive featureset comes with a hefty pricetag – in my case, just exceeding $2000. However, it would seem that the cost is justified.

Software: The software should pick up where the hardware leaves off in excellence. However, in the case of the SZ650, it absolutely does not. Sony made the enormous mistake of loading a business branded laptop full of Trial softare, better known as “bloatware” or less elegantly, “crap.” Even worse, Sony does not include any sort of Operating System disks, so I couldn’t format the machine and remove the junk. Its not like there were a few programs installed for my convenience, the system was loaded to the gills with unnecessary and infuriating software. They even included a full length, multi gigabyte copy of Spiderman 2 that could only be played through their proprietary software, which I would consider hardly appropriate for a business notebook. This alone was almost enough to make me return it to the Best Buy where I had purchased it, but I was able to do a clean install using a Vista disk that I already owned.

Believe it or not, it was actually downhill from here. Sony’s (necessary) driver utilities are poorly built, resource intensive and barely functional. The ingenious-on-paper “hybrid graphics card” system, which allows you to switch between dedicated and integrated graphics to save battery life in situations that do not require dedicated graphics power, is crippled and very close to useless. Not only does it require a full reboot to take effect, the switching utility actually stopped detecting when I had changed the switch after about a week. I eventually did another clean install of Windows Vista and the driver resumed working (only to fail again). The wireless drivers were also questionable and often resulted in dropped connections while signal was excellent. I tested the Vaio alongside my Apple Macbook Pro (reviewed here), and it experienced no problems with wireless where the Vaio struggled.

Build Quality: In my time with it (about a month of constant use), the Vaio held up fairly well. However, shortly after I sold it (due to the immense number of problems I had with the software), the buyer complained that the left-click button had ceased to function and he also was experiencing some problems with the screen. I verified these problems and helped him work with the warranty to have it repaired, but no laptop should have significant hardware issues in the first month of ownership.

In conclusion - I hate to say it, but I do not recommend the Sony Vaio SZ650. For what its worth, the Dell XPS m1330 has an almost identical configuration available and I would be inclined to choose the Dell over the Sony in a future situation where I needed another laptop in this category. The SZ650 appears nice on paper and looks good on the surface, but that beauty is only skin deep and the prevalent problems keep me from recommending it. Look elsewhere for a 13’’ laptop with dedicated graphics, as Asus, Dell and others off comparable models without the garbage pre-installed and hardware quality issues.
