Power And Temperature Benchmarks

System Builder Marathon, June 2010: $1,000 Enthusiast PC
By

At stock speeds, the $1,500 Core i7-920 system uses relatively little power and is in the same league as the $1,000 Phenom II X3 720 system. But when overclocked, the Core i7 machine is significantly more power-hungry. The overclocked/core-unlocked Phenom II X3 720 build doesn't really require a tremendous power increase over its stock draw, but it does consume more.

The $1,000 system's temperatures remain quite low, even when overclocked. But the $1,500 machine's components do appear to build up a lot more heat, especially when overclocked.

    When you say SBM: Enthusiast System, I am expecting this to be more than just another gaming rig. You may have your own reason for sticking to a Phenom II x3 720 and HD5830 crossfire but I believe a Phenom II x4 955 and HD5770 crossfire would make more sense or more well-balanced (instead of trying your luck by unlocking cores). In fact, we could also grab a HD5870 and downgrade our mobo a little and that would make a truly well balanced enthusiast system.

    I find it surprising that you are always successful in unlocking the 4th core

    one-shotIt would have been nice to see the PII X6 1055T with a moderate downgrade in GPUs to afford the higher cost of CPU and motherboard. The i7 embarrasses the PII X3.
    If you're going to make this about i7, you can point to the $2000 system and I can point out the 100% price difference. Do you really think the $2000 system is "more" than 100% better?

    I'm with one-shot, 6core AMD for $200 can't be beat.

    not a fan of the 5830's or the 720 cpu choice is all.

    Would have rather seen a dual 5770's or a 5870 with a i5-750 or a 955

    games more and more are using cpu for doing things. I also tend to use a comp for other things more then games.

    A phenom II 955 BE:160$+2 Xfx hd 5770sfor320$+GIGABYTE GA-890GPA-UD3H for 140$=620$ would certainly have been a better choice than your 670$ for CPU+GPU+mobo.

    A Thermaltake V3 instead of the Antec 300 would have saved you $15

    I've succeeded in unlocking cores in 3 out of 3 tries, but the point stands, buy the processor you want right off the bat. Imagine if it were a dud. 1055T is the only AMD processor on the market worth thinking about.

    This isn't about i7, but rather a better CPU choice. I would rather point to the $1500 system that the current system is being compared to. The $2000 system is twice the price, hardly comparable to a $1000 system. We both know there are marginal gains the higher the system cost is. In the graph above, it says September 2010, but I'm going to assume it was a misprint intended to be September 2009. Even so, prices have changed in that time frame.

    From the stock speeds of the June 2010 $1000 SBM, to the overclocked $1500 September 2009 SBM, one can see the large difference in performance for a relatively small increase in price. Even the overclocked speeds of each system leave a lot to be desired from the PII X3 system. However, another i7 build would be more of the same. It would be nice to see something different rather than two powerful GPUs limited by a slower CPU.

    I probably would have started the list with a n X6 1055T, but I can appreciate Don's desire to save money for graphics. Were gaming my overwhelming concern, I would have angered everyone by picking an i3-530 for its overclocking capability. Either way, I wouldn't characterize the X3 720 as an embarrassment.

    That's a whooping 48,000 pesos in the Philippines, I could build a more powerful rig with locally available parts.

    i5-750 or the 955 (as mentioned in another post)is where you should have gone unless you want hyper threading, in which case i recommend the i7-930 though it costs a bit more total system-wise, i would have been able to do it), or the 1055T (even if it doesn't have HT 6 physical cores is as good in my opinion, especially for the price.)
    also i would have gotten the Seagate 7200.12 500GB you can find it for 42 and free shipping. my system that im building now (bought 4 JUNE)

    specs:
    Phenom II x4 955
    ASRock 870 Extreme 3 (allows for xfire on a 870 board)
    Sapphire 5770
    OCZ platinum DDR3 1333 7-7-7-20
    Xigmatek Midgard
    $20 optical drive
    Antec EarthWatts 650W 80Plus
    Seagate 7200.12 500GB
    Total: $742

    If i added another 5770 would perform simmiler and even if i added another 5770 it would only cost $890, at that price you could also add in a good air cooler, and more fans for the excellent case i got. and i would only be at $960, oh i forgot to mention that the price includes the operating system, if i take that out (since it isn't included in the system builder marathon) the price is actually $870 for everything mentioned.

    i received discounts from combos and searching Google shopping, and came up with a savings of about $210 on this system.

    I really can't see why they always stick to high end crossfire and skimp on the CPU either, at $1,000 it simply doesn't make sense to me to have anything less than a Phenom II x4(or x6) or an i5-750. I'd much rather see a slightly higher end single card, or 5770's if you really insist on crossfire to make up the price difference. Then again I do a fair amount of CPU-intensive things and have yet to want to play anything that didn't run fine on my 8800GT imo, so maybe I'm biased.

    How does it do that?

    Brilliant build man! Stellar performance for the money!
    And while I wouldn't let myself build such a potent system without front fans or with this puny hdd the temperatures were in check and hdd isn't tested much here so these sacrifices are acceptable considering the circumstances.
