The Toshiba Qosmio X770 sports the latest second generation Sandy Bridge processor, and is based on the same chipset as the HP Pavilion dv6, one of the latest multimedia laptops we've reviewed in recent times. For comparison’s sake, we also selected the MSI GT660, one of the better gaming machines we have had last year, to illustrate where today’s powerhouse machines stand in terms of performance.
But something interesting to note is that today’s multimedia notebook with discrete graphics is almost on par with yesteryear’s gaming grade notebook which used the best mobile GPU available then. This probably gives an insight into what actually contributes to the X770’s stellar performance over the MSI GT660. We’re inclined to attribute it towards the advancements made in the latest NVIDIA GeForce GTX 560M (at time of writing, but now taken over by the newly released GTX 580M) GPU giving it much higher graphics processing throughput.

In our PCMarksVantage test, the Qosmio X770 pulled ahead (8224) of both other notebooks by a large margin. This is partly thanks to its discrete graphics card, which gives it extra firepower in terms of 3D scores that boosts its overall scores. The extra RAM and speedier hard drive also contributed to the scores but it pales in comparison to notebooks packing SSDs, which have scores in the five-figure range. So for gamers who would like to push the machine’s potential to the limit, it wouldn’t be too far-fetched to actually consider swapping one of the two already fast 500GB 7200RPM hard disks for an SSD to increase its overall competence exponentially.
In our 3DMarks06 test, the Toshiba naturally trumps over the other machines with scores well over 16,000, thanks to its powerful discrete graphics card. And if you aren't convinced yet, then you need to know that the scores were for full HD resolution, while the rest were running the benchmark on 1024 x 768 pixels resolution. Of course contributing to the end results are the faster Core i7-2630QM processor and 8GB of RAM. A powerful GPU these days also provides many more advantages besides gaming. Some software that have traditionally taxed the CPU to its limit have also recently been made to take advantage of the system’s GPU (think Photoshop) in order to get rendering or encoding done much faster, easing reliance on the CPU, freeing it up for other tasks.
Far Cry 2 (Updated as of 15th October 2011)
If you need further proof that the writers here at HardwareZone are as "hardware" centric as our name suggests, here's one for you. We've recently retested the Toshiba Qosmio X770 and the latest updated iteration of the HP Pavilion dv6 which features a new Core i7 processor that has a higher clock speed. Unfortunately as they are notebooks different classes, we only have scores based on resolutions tied to their class. The Qosmio X770 was tested on a full HD resolution (1920 x 1080 pixels) while the dv6 was tested on the usual 1024 x 768 pixels. The Toshiba Qosmio X770 still scored fairly well compared to the newer gaming notebooks sporting newer graphic cards. At the time of its initial testing, the Qosmio X770 was also the highest specced machine available in the market, but has since then its NVIDIA GeForce GTX 560M has been outclassed by the latest NVIDIA GeForce GTX 580M found on certain newer machines. After the retesting has been done, we've also found out that certain circumstances had led to the Qosmio's inflated Far Cry 2 scores, and the new scores reflected here are the result of several rounds of benchmark testing. The Qosmio's impressive scores here indicate that the X770 is not only an adequate gaming machine, but it's also capable of handling semi-intensive graphical work such as photo or video editing. Don't expect it to replace a desktop though, because the graphic card its running is a mobile variant, and is meant to consume much less power than a desktop graphic card.
