Gaming Resolution Scaling

As the previous gaming benchmarks appear to be GPU limited in most cases, we wanted to take a look at performance at a couple other resolutions. 1280x1024 is a common resolution for LCD users while 1920x1200 is becoming very popular at the high-end. Given that we are already GPU limited at 1600x1200, 1920x1200 will be even more GPU limited. However, "GPU limited" does not equate to "slow" as performance in most of the tested titles is still more than acceptable at this resolution. We included additional games in these comparisons, and since we are performing all of the tests solely on the ABS system the difference between CPU clock speeds is more meaningful, and the margin of error is much lower (less than 1% between runs).

We will also include results from running the games with sound enabled using an X-Fi card, where applicable, to show the performance impact of enabling audio. We would like to take a moment to state that the onboard audio on the Intel motherboard is a far inferior solution compared to other offerings, and we would definitely recommend the purchase of a Creative Labs X-Fi soundcard for anyone looking to buy/build a high-end gaming system using this board -- really we would recommend an X-Fi for just about any serious gamer, and audio professionals would want to look at other add-in cards as the onboard audio is at best adequate in most cases. The Sigmatel audio does not support EAX at all, nor does it support OpenAL. Games which use OpenAL will be limited to stereo audio, and the sound quality was clearly inferior in all games even with $50 Logitech 5.1 speakers. We won't report gaming performance using the onboard audio, as it was not doing the same amount of work as the X-Fi card.





















The drop in performance when going from 1280x1024 to 1600x1200 and from 1600x1200 to 1920x1200 is a clear indication that we are almost completely GPU limited in all of the games at the tested settings. At the lower resolutions, there is a slight separation between the three benchmarked clock speeds, but nowhere near the 32% difference in CPU speed. Unfortunately, we do not have an equivalent NVIDIA configuration for comparison included, but we expect results from 7900 GTX SLI to be similar overall: slightly higher in some cases and perhaps lower in others, but still mostly GPU limited. That said, the good news is that performance is more than acceptable in all of the tested games at the tested resolutions.

Note that the results provided here for Serious Sam 2 and Quake 4 are from a different versions of the game/demos and are not directly comparable with the results on the previous page. The HOC benchmark utility was used to run Quake 4 tests for comparison with the motherboard reviews, whereas the Quake 4 benchmarks here were run manually, and we also included a standard single player Q4 timedemo. (The HOC utility does not properly support widescreen resolutions, and it does create a slight overhead when benchmarking, so in order to be internally consistent all of the tests here were run manually.) The results from both the TimeDemo and the PlayNetTimeDemo are nearly identical, other than the fact that the NetDemo scores about 15% lower. The previous page used version 2.070 of Serious Sam 2, and the Branchester demo provided is very different from the version provided with 2.066. Results are internally consistent however, and this simply highlights the fact that no single benchmark can demonstrate what performance you will experience in every situation.

Call of Duty 2 showed some significant variations between benchmark runs with audio enabled, and it also experienced periodic display corruption. This once again leads us to the conclusion that the GPUs can get overly hot and cause problems due to lack of waterflow. We were eventually able to get consistent scores, but the margin of error -- at least with audio -- was much larger than in other tests.

F.E.A.R. also returned some odd results, as it performed better at 1600x1200 than at 1280x960 in nearly every test. We are apparently becoming CPU limited, but it also seems that the drivers and/or game are not fully optimized for certain resolutions. 1280x1024 scored about 10% lower on minimum frame rates than at 1280x960, and came in at 82 FPS average frame rates. The minimum frame rates on all tested configurations were significantly higher at 1600x1200 than at either lower resolution (roughly 45 FPS at 16x12 vs. 30 FPS at 1280x960).

Notably missing from our benchmark results is Oblivion. Attempts to run Oblivion on the ABS system with CrossFire enabled initially resulted in a black screen. The audio still played, and we could exit the game by using the appropriate keyboard shortcuts, but the only way to get the display output to work was to disable CrossFire. We haven't been able to figure out the exact cause, but Oblivion has now started to work properly. It could be the addition of an X-Fi card (the system was initially shipped without one), or it could just be one of the various CrossFire bugs that people encounter. It could also be a peculiarity of the Intel BIOS/motherboard used. We are still investigating the matter and will report on the matter in upcoming system reviews, along with providing Oblivion scores for the ABS X9.

Out of all the games tested, only two currently show a moderate difference in performance with increased CPU speeds. Battlefield 2 is one title that really sresses the CPU, and the added CPU speed improves performance by about 5% over a stock X6800 at 1600x1200. Far Cry also shows a significant performance increase, though this is in part due to the level being benchmarked (River). This particular level is extremely taxing on the CPU, and the results are actually CPU limited with everything but the 3.52 GHz configuration. The majority of levels in Far Cry do not appear to be as demanding of the CPU.

All of the latest games score almost identically at 1600x1200 and 1920x1200, even with X1900 CrossFire driving the graphics. Optimizations in the ATI drivers may improve performance some, but we don't expect X1900 XT to be CPU limited at high detail settings and high resolutions with any of the faster Core 2 processors. X1950 may change that assessment when it becomes available, but for now the fastest GPUs are not able to keep up with Core 2. That's really not all that different from the previous champion, AMD's Athlon X2, and performance results from a top AMD system at these settings would also be very close.

    Ah sorry, forgot to add, or ask rather, why do tech sites such as yours review OEMs anyhow ? Server equipment I can see, but a gaming / desktop system, I could never understand. Most people who read your site are very technical, and while I cannot speak for everyone, I think its personally a waste of time for you, and your readers(since most of us build our own systems anyhow). Also, again while I cannot speak for everyone, all my systems have_to_be stable, and when I build my own system, they usually either start off stable, or get fixed in the building the system (ironing out flaky software issues). I do not see how a OEM, who is serious about thier product, can put out something that isnt stable, I mean they have a hell of alot more resources than the average Joe such as myself, and yet, ever system I've built over the last 6-8 years (been building my own systems since 92 or earlier) has been 100% stable, usually from the get go. Then again, those of us who are tech savy, know that you never skimp on 3 parts EVER, Motherboard, memory, and PSU . . .

    I don't think ABS intentionally skimped on anything here. The problem is simply that they're working on the bugs on a design - I'm not sure if the GPU watercooling is actually coming on any systems right now, but they have said that a new GPU cooling solution should be ready in a month or so.

    As for why we review OEM systems, I tried to make that clear in the intro. 1) Not all people build their own PCs. 2) Core 2 is currently a bit difficult to find at retail, and you have a better chance of getting it in an OEM system As for the readers, trust me when I say there are a LOT of readers that never read the comments section or post here; with literally millions of readers (Anand could give actual numbers), we basically cater to every corner of the market.

    Speaking of 100% stability, I'd wager a lot of systems would be somewhat unstable under the extreme test scenario we used. Two instances of Folding@Home along with running games (real games and not just a demo loop or 3DMark) for hours on end can cause problems on a lot of the overclocked "100% stable" enthusiast systems. I've had Dell and other OEM business computers take a dive in such a scenario.

    Although not all people build their own computers, I'm sure that if you set up a poll, you'll see that a huge majority here do, so spending all the time on this article is just good comedy for me to laugh at what 13 year old's father is going to buy this for his kid so he can play Counter-Strike on while running 5 viruses simultaneously.

    As for the stability under 2 instances of F@H with a game on for hours at end... I'm sorry but who on this website is purchasing a computer here for NASA? Anyone? We're not counting the extreme nerds running F@H for a few years until they manage to lose their virginity. Running math programs for hours on end is not exactly my idea of fun or productiveness. There's a huge difference between stability and "stability in case of a nuclear meltdown while running 30 instances of F@H while your wife is screaming at you and your kids are playing with matches".

    Stability for most of us means we can run a few programs (a media player, a game, a bittorrent program, a trillian-esque program, and a few other things) while focusing on the game experience and making it top notch and not crashing.

    And I wouldn't doubt the ability of a Dell or other OEM business computer to take dives in any situation. That's why most of us don't buy OEM. We like to know how it's getting put together. If you need any more go find some pictures of those Apple laptops that used to ignite themselves and what they looked like inside.

    Most people may not plan on running two instances of Folding@Home while playing games, but doing an SMP capable video encode (i.e. DivX) while running a game would place a similar stress on a system. Do you all want to know that a system can run stable under moderate use, or do you want to know that it is truly stable? I suppose we could just run SuperPi 32M once, and if the system completes without errors it must be fully stable, right?

    Who really knows what programs are going to be like in another year or two -- we might get games that can fully stress both processor cores on their own, along with completely stressing the GPUs. Certainly there are no current games that do that, as Quake 4 tops out at around 75% CPU usage with two cores and that's higher than Oblivion and Call of Duty 2.

    Anyway, what else are people going to use quad core or even octal core systems to run at home? At least with Folding@Home people can feel that their computer is doing something potentially useful with its spare clock cycles rather than just consuming electricity. It's also somewhat humorous that you talk about all of the people here who build their own systems and then make fun of the "extreme nerds" that run Folding@Home. (Most "normal" people in the world would consider both parties to be "extreme nerds", but I digress.)

    The bottom line is that you can't call a system 100% stable and less you truly stress test the system. As any experienced overclocker can tell you, there are really only two types of systems in the world: those that appear stable because they have not crashed yet, and those that you know are at least somewhat unstable because they have crashed. Under the right conditions, I think the vast majority of computers are at least partially unstable. I guess that's okay, though, and we should all return to the days of Windows 95 when daily reboots were practically required?

    Still, the system I'm writing this on is a socket 754 3200+ Newcastle overclocked to 2.42 GHz, and it routinely runs for weeks on end without rebooting. About the only time I reboot is when I have to install one of the updates from Microsoft. It also runs Folding@Home 24/7 in the background. If that eventually causes my CPU to fail, it will probably be time to truly upgrade anyway. (Odd that I haven't switched over to one of my newer systems, but this one just does everything I need it to do, other than intense gaming. It's kind of nice to have a computer where I don't need to worry about gaming performance, as probably 95% of my computer crashes that have occurred in the past five years happened when I was playing a game.)

    Yeah games cause alot of crashes on PCs but thats not to say its the hardwares fault. If it happened all_the_time then possibly, but the random crash once in a blue moon should not be attributed to hardware issues (atleast IMO).

    Re-read the post above where I said my PCd frequently stay up for months on end . . .;)
  • yyrkoon - Saturday, August 19, 2006 - link

    PCs, sorry, you guys really need an edit function hehehe
  • yyrkoon - Friday, August 18, 2006 - link

    Well thats kind of harsh on any system, running all those apps at once, but I've always been in the school of thought that IF you're going to game, game, and dont try to run 500 application all while doing so. If you really want to crash ( or maybe just CTD a game), run Oblivion ;) Still. if you managed to crash any system running all that, I would consider that a software issue (OS, or appliction), and not hardware.

    As for ABS intentionally skimping on hardware, well, all it takes is a little research, and all those worries go away (usually). I did notice they are using a tier 1 motherboard, which is probably a good idea, but I will bet any one of us could build the same system for half the cost. Anyhow, with sites such as yours, reviewing motherboards, memory, and such, there is no excuse for anyone really, to buy 'crappy' equipment, hell, I only paid $54 usd for my current motherboard (AM2 system), but its very solid . . . care to guess who made it ? At any rate, its merely a steping stone in the dirrection of where my system will be this time next year.

    Anyhow, what I consider 100% stable, is a PC that is used normally (which for me, I use my systems all day everyday), for gaming, and work, and able to stay up for months on end without having to reboot (not including installing drivers, etc.), BSoD, or crash applications constantly. I havent seen a BSoD on any of my systems in a long time (years?), because of hardware issues. This is not to say I'm special, this is just to say that even in windows, its very possible to build a rock solid system (in-exspencively), with uptimes approaching Linux server status, you just need to pick your hardware carefully. Overclocking shouldnt even be used in the same sentance as stable in my opinion, these systems MAY run fine for a few years, but OC'n will usually eventualy kill a system, and I consider it a good thing, if systems last well past 3-5 years.

    Now, to be honest, I must say I only skimmed this article, since I'm really not interrested in OEM systems (well, I usually recommend Dell to clients for a cheap OEM systems, depends on needs), but I personally havent had any problems finding C2D CPUs (except for the 6800 extreme CPUs, which is out of my price range anyhow).

    Now, if I may offer a suggestion, I personally think it would be cool if you guys linked these comment sections to your forums.

    Hehe, thanks! I'm looking forward to the "I don't have to sell my kidney on e-bay" computers!
