System Builder Marathon: $1,250 Mid-Range PC

Synthetic Benchmarks

As usual, I like to start with 3DMark Vantage, just because it's the gaming-oriented synthetic benchmark.

3DMark Vantage changes the weight of CPU vs. GPU depending on the preset you run. At the lowest detail Performance preset, the benchmark is weighted towards the CPU and at the highest Extreme preset, it's weighted towards the graphics card. We can see the results of this clearly, as this month's Core i7/Radeon 4850 X2 combo scores better with the lower-resolution Performance preset. But by the time we hit the high-resolution Extreme preset, last month's Core 2 Duo E8500/Radeon 4870 X2 combo takes the win thanks to the more-powerful graphics card.

This vaguely mirrors what we expect to see as a trend in most games, but real-world titles are likely to show us a much stronger preference towards either CPU or GPU power. I would guess that most of our game benches are more GPU than CPU limited, but we'll see about that in a bit.

Now let's move on to Futuremark's productivity-oriented benchmark, PCMark Vantage:

Wow. According to PCMark, the stock Core i7 920 absolutely slaughters even the overclocked Core 2 Duo E8500. These are synthetic numbers but they probably give us a good indication of how the productivity benchmarks will perform, at least in multi-threaded applications. Remember, the i7 920 is a quad-core processor compared to the dual-core E8500, so these scores probably reflect that.

Now for the final synthetic bench, Sisoft Sandra XII:

Wow again! Sandra seems to indicate a colossal advantage for the new Core i7. Frankly, this looks a little disproportionate and I don't think the real-world benches will demonstrate this level of superiority.

But why guess, let's see for real. The media-encoding benchmarks are only a page away...

  • Personally I'd get a cheaper processor and motherboard and go with a Gforce 280 video card. You can get a $180 processor and a $145 motherboard and the 280 card has PhysX built in which is really nice.

  • I will hope to see how a high-clocked q9550/q9650 E0 will compare with a i7 920. The Motherboard and RAM will be cheaper. So, you can also get more RAM and faster RAM with the q9550 than the i7 920 with the same cash. Or the high-bandwidth/ lower total memory DDR3 tri-channel might actually do better?
    I don't think a i7 920 /w 3 gigs RAM will work as quickly as a q9550 @ 4.0Ghz with a 470mhz fsb and 4+ gigs RAM -even with quad-core supported apps.
    Anyway, I think the outcome will be hard to predict.

  • I think the Q9550/i7 920 comparison would be very informative. I have been considering purchasing a Q9950 in the near future. Let's see it happen.

  • I agree with I'd agree with trying to run a comparison with the Q9550. Throwing in an nvidia card would also prove interesting.

  • Very good article. I just want to say that the Crucial 3GB triple-channel DDR3 1066 kit costs only $73.99; its price surprised me. Go Crucial! I'm definitely looking into a Crucial memory kit for my next upgrade or build, which might or might not be Core i7, depending how the price wars progress between nVidia and ATI (saying AMD still feels wierd to me when referring to video cards). I noticed how the budget had to "settle" for a 4850 X2 when they Core 2 Duo build had money for a 4870 X2. Hopefully, prices will go down faster, and soon.

  • Page 2 - E8500 has 6MB L2 cache, not 4MB.

  • Yes, please try the next system with the Q9550! I would love to see how this processor compares again the new kid on the block. Of course this is the processor I have and also want to see what you get out of it. It would be nice if you chose another Gigabyte board as well to get a more apples to apples comparison with this month's build.

  • Yes we want to see Q9550 against Core i7 920. Both overclocked at the same speed. Let's say 3.8 or something like that.

  • Good article, well done. At first I was a bit worried for the Core i7 was going to get humiliated against the higher clocked E8500 but you summary shows just how much progress has been made with developing software that can take advantage of multiple cores.

    The Supreme Commander: Forged Alliance benchmark was surprising out of all the games you tested I expected that game to be the one which showed off what quad cores can do for games. Perhaps you could add in GTA IV into your future benchmarks as that games seems to love quad cores?

    The temps were a little worrying but the Intel Stock cooler isn’t designed with overclocking in mind and you can pretty much guarantee a decent 3rd party cooler will slash those temps by a third.

    One last thing it might be an idea to compare your very first mid range build to your current mid range build, it would give the readers an idea as to how much more bang for buck we get now days.

  • well 4850x2 there is only two in newegg 2gb and 1gb which not sure if ATI rly supported as far as drivers compared to its bigger brother

  • I read this and I suddenly start to cry ... you may have read before that figures in Euros are equal to figures in Dollars ... but things got worse and worse.

    The current prices in an average shop in Spain:

    Intel Core i7 920 : 293 EUR = 413 USD
    GIGABYTE GA-EX58-DS4 : 219 EUR = 308 USD
    Sapphire Radeon 4850 X2 2 GB : 349 EUR = 492 USD
    6 GB Patriot DDR3-1333 CL7 Kit : 259 EUR = 365 USD

  • spain lol

  • And yes, please include a GTA 4 benchmark. I got more FPS from overclock my C2D 700MHz than overclock my 9800GT 100Mhz.

  • The Q9550 would be interesting because it would show how much gain is from the change from Dual to Quad core and how much is gain from the new i7 architecture. This comparison is very relevant to everyone buying/building a new quad core system right now, especially around this price range.

    What I would really like to see is the new i7s on the CPU charts.

  • I think it would have been cool if you would have used two 512mb 4870's in crossfire instead of the 4850 X2. I think there would have been a different trade off in memory amount but I think the added speed of the i7 might have offset it nicely.

  • I guess core i7 is strictly suited for high end systems ($2000+), where the added costs of memory, mobo and cpu are justified. for low to mid range systems it is too much to bare.

  • In the next SBM we should watch the brand new GTX 295, keep it in mind, folks ;)

  • I'm kind of surprised that you folks chose a new i7 for a "Mid Level" system.

    You've upgraded the processor, but downgraded the video cards from last month.

    "Not really. The i7/4850 X2 still performs at about 80% of the level that the E8500/4870 X2 is managing to achieve."

    Of course this new system performs less than the November one.

  • I understand you keep Vista 32 to make it easier to compare to the previous systems, but in reality you should really upgrade to vista 64.

    You have a total of 3.5 gigs of memory to play with in vista 32. Since you only put in a graphic card with 2gigs of video memory that leaves 1.5 gigs of memory for normal applications and the OS. Anybody that reads these system builder marathons are going to put vista 64 on their computer if they are going to use vista.

  • Your chart regarding the base and overclock settings of the Dec. pc on page 7 is inaccurate. (Ram and Graphics card.)
