Gaming Performance — Resolution Scaling

Considering the rather low-end CPU, you might expect that there are many situations where the GPU is held back. With the initial native resolution benchmarks out of the way, let's look at performance scaling at higher resolutions. Since we become more GPU limited, the Gateway P-6831 FX actually closes the gap with some of its more expensive competitors.





































There are obviously a few titles where we are still CPU limited even at 1920x1200. Battlefield 2 and Far Cry for example have virtually flat resolution scaling curves. Other titles — Bioshock, Crysis, Oblivion, and Unreal Tournament 3 — show a pretty sizable gap between the 8800M GTS in the Gateway and the 8800M GTX in the AVADirect notebook. However, it's not entirely clear whether that gap exists primarily because of the discrepancy in CPU performance or if the added Stream Processors are the culprit. While it certainly would have been interesting to test with an upgraded CPU, we didn't have any Core 2 Duo processors readily available (nor the time to rerun all the tests).

Regardless, the net result is that we can't help but be impressed by the Gateway system. In some of the titles, the difference between the 8800M GTS and the GTX is virtually nil, particularly at higher resolutions. Since the GTS and GTX both have the same amount of memory, the same memory bandwidth, and the same number of ROPs, it's not all that surprising that some games hardly show a difference between the two graphics chips. It's unfortunate that we haven't seen any manufacturers giving customers the choice between the GTS and the GTX; we wouldn't be surprised if more than a few people would be happy to sacrifice a bit of performance in order to save a couple hundred dollars. Since that isn't an option, we recommend the Gateway P-6831 FX as a very reasonable alternative.

    It looks as if at least Best Buy is also shipping models only with 7800mAh batteries now. So it could be that this whole 2600mAh thing was quickly changed. But basically if you buy one now, you are getting the bigger battery and it is certainly not an option to go smaller. Now for the display, I will let you know. I know for a fact it didn't have a battery jutting out, so that could be a 2600mAh or hey, none at all. If that's the case, it's an honest mistake. I will check the next time I work. But current research points at everyone getting a 7800mAh and no option now to go smaller. In fact, on Gateway's website, they removed the 2600mAh spec. Reply

    If you don't mind a little constructive criticism, the car analogy in final conclusion is way over done IMHO. After that first sentence, everything else could have been deleted. We got it, move on. It just seemed like filler to me.

    I actually really liked the car analogy! It could relate because a laptop "on the go", just like a car. The performance comparisons between laptops and cars are also very true, so I can't agree that it was filler as it did illustrate an important point about the performance characteristics of the laptop compared to others. Also, I think the idea that it is an "everyman" sort of laptop that is specifically capable for gaming at a great price makes it a perfect fit for alot of gamers who would probably be able to upgrade every couple years anyway. Obviously most people aren't going to spent $4000 on a laptop anyway. Reply

    The latest Intel chipsets are able to run dual-channel with mismatched memory sizes, as the others above pointed out. There is a small performance penalty, but in truth RAM performance isn't the primary bottleneck, particularly on notebooks. Look at the WidowPC vs. AVADirect scores - the AVADirect uses faster RAM, but performance is still a tossup.

    Someone mentioned bloatware, and in the midst of testing and finishing things up, I neglected to cover that topic. The laptop does indeed come with a lot of crap software installed. However, it's not necessary to do a clean install - I just uninstalled all the extra stuff and that's what I tested. It took an hour or so all told (the internet security suite takes a while to remove), but the result is a much leaner setup. Highly recommended.

    If you want to upgrade the CPU, my recommendation would be to go for the T8300. eWiz http://www.ewiz.com/detail.php?p=T8300BOX">has it for $240, and it would totally remove the CPU bottleneck in games. If you want to go for the T9300 to get the additional cache and 100MHz more, http://www.ewiz.com/detail.php?p=T9300BOX">it costs around $320, so I'm not sure it's worth the money for most people.

    Folding@Home can run on the system - that leaves the CPU fan on max, which may reduce the life expectancy of the fan (okay, it *will* reduce the fan life), but it's not terribly loud. With the T5450, however, Folding@Home SMP needs to run pretty much 24/7 to complete work units within the alloted time.

    Regarding temperatures, a lot will depend on the operating environment. During the winter months when few houses or offices are much above 70F, I doubt many will complain. In the summer, I imagine it will be quite a bit warmer. This is at its heart a desktop replacement, like all other 17" notebooks. You can carry it around and use it on a bus/plane if you want, but that's not the primary intended role. At maximum load after 30 minutes the bottom of the laptop gets relatively warm... I'll run some tests quick and update the article in the next hour or so.

    Finally, a bunch of people complain about my mentioning the ASUS G2P. Here's the deal: the G2P was a $1900 laptop when it launched, and in my review at that time I loved the LCD but lambasted the weak GPU choice. Only laptops with a Go 7900 GS were adequate, but those cost well over $2000 at the time (not counting prices obtained via auction sites and short-term sales). The G2S is a decent notebook today, but NOT FOR GAMING! Look at the results from the Toshiba X205; that includes an 8700M GT, which is moderately faster than the 8600M GT in the G2S (higher clock speeds). The X205 had a T7200 (more cache and a 2.0GHz clock) and the P-6831 already outperforms it by up to 100%! The G2S is a great multimedia laptop, but gaming performance is still very weak. If ASUS had a laptop with an 8800M (GTS or GTX - I don't care) in it, I'd be all over it. If they could do it for $1500 or less, then the Gateway P-6831 would have some competition.

    Can anyone confirm that the T8300 or T9300 work in this laptop?

    I saw a post that someone fitted the laptop with a 65nm T7500 but I've seen no mention of the 45nm T8300.

    Thanks.

    The higher end models of this same chassis ship with Penryn chips, so it *shouldn't* be a problem putting a T8300 in a lower-end FX system. Reply

    Thanks for the Folding @ Home info! I hope it'll do okay. Wish laptops were like desktops where it just doesn't matter :-/

    I'm kind of baffled by this dual channel with mismatching DIMM sizes thing. I've never seen that covered in chipset reviews. I guess it's leaving SOME of the RAM in dual channel mode, and some (the left over 1GB)? Weird. So just randomly some memory accesses would have double the bandwidth of others.

    It's been around since the Intel P965/975X chipsets. It's called Intel Flex Memory Technology. All I can find on the subject says that it "Gives users a more flexible memory upgrade option by allowing different memory sizes to be installed while maintaining dual-channel mode/performance." There's no clear indication of what exactly they're doing (maybe in a white paper somewhere?), but I suspect the interleaving of data between the memory channels is modified in this arrangement. Performance may not be as high as a matched dual-channel config, but it's still better than single-channel.

    Of course, last I recall seeing this tested, dual-channel only improved actual system performance by 5-15% depending on the platform. Since notebook chipsets are already bottlenecked by a slower FSB, the improved memory bandwidth probably doesn't matter that much. The FSB is 133MHz base, quad-pumped. The RAM is 333MHz base, double-pumped. Both deliver the same bandwidth before dual-channel ever comes into play.

    Thank you for updating the article with temperature info! That is definitely something you can't infer from the spec sheet.
    Nice job!

    Back in October '06 I bought (via ebay) a new Dell Inspiron 9400, 100GB 7200HD, Geforce 7900gs, 2gb ram, T7200 processor, 1920 X 1200 screen for $1684. I've since updated it with a 200GB 7200HD and 4gb DDR667 RAM.

    It doesn't really seem like there's much more bang for the buck today than when I bought my machine a year and a half ago. Perhaps the most sensible upgrade right now would be to replace the 7900gs. Does anyone know if this is possible?
