We had a significant amount of requests for Flight Simulator X results in our Core i5/i7 and P55 coverage. I was able to run some quick comparison results between the Bloomfield and Lynnfield platforms last night to answer most of the email and comments requests. However, I am still running the Phenom II and Core 2 Quad benches. I do not know if we will be able to have those results in our P55 roundups that start in a couple of days. If not, I will follow up with these particular performance updates in another blog.

Test Setup-



We are utilizing our standard P55/X58 setups for this test. The 920/860/870 platforms are using 7-7-7-20 1T DDR3-1600 memory configurations. The 750 platform is running at DDR3-1333 with 6-6-6-18 1T timings since the 12x multiplier is not available on the i5/750. The X58 platform is equipped with 6GB of memory and the P55 with 8GB. Turbo mode and Hyper-Threading is enabled as designed and shipped from Intel. All other BIOS settings are at stock ratios.



We enabled DX10, AA/AF, set the Aircraft, Scenery, Weather, and Traffic sliders to Ultra High, and then measured a pre-recorded six minute flight around Honolulu with FRAPS at 1920x1080. Our variability with this benchmark averages around 0.5%. The benchmark is run five times with the median score reported for our results. FSX responds well to both increases in GPU and CPU improvements, but especially differences in CPU clock speeds.


Gaming Performance - Flight Simulator X

When overclocked to 4.2GHz, the 920 and 860 are basically even in this title. The big differences though are the improvements in frame rates, especially the minimum frame rate with a 36% increase compared to the stock 860/870 results. The average frame rates increase 14~21% over the 860/870 stock results.

Due to very aggressive turbo modes, the 860/870 offer the best performance at stock clock settings. No real surprise there, but the improved turbo mode on the i5/750 does allow it to stay even with the i7/920 in this title. All of the processors offered a very enjoyable gaming experience as minimum frame rates were excellent, especially when the processors were overclocked. For those originally wondering, the i5/750-P55 combination will not have any problems running this title at 1920x1080 resolutions with Ultra High quality settings.

OCZ Technology

OCZ recently sent us their upcoming DDR3-2400 C9 4GB Blade series kit. The official specifications call for 9-10-9-24 1T timings at 1.65V VDimm on the P55 platform. We tossed it in our Gigabyte GA-P55M-UD2 motherboard with an i7-870 overclocked to 4.2GHz (21x200), set the memory multiplier to 12x for 2400MHz on the memory, and manually set timings to 9-10-9-24 1T, VDimm to 1.65V, VCore to 1.375V, and VTT to 1.370V.





The OCZ DDR3-2400 Blade kit worked perfectly at its rated specifications on one of the least expensive P55 boards you can purchase. We will have further results shortly.

TankGuys

I normally do not do this, but we were needing a couple i7/860 processors plus a few additional Intel G2 80GB SSD drives quickly for the 860 review and for the expanded motherboard test suite. Normally, we would go to the larger e-tailers like Newegg or others for these items. Well, I was not satisfied with the pricing or availability on either item, so I hit up Ben at TankGuys to see what he could do for us.

Let's just that TankGuys came through with flying colors. Not only did they ship the items before Newegg had them in stock, but their prices were extremely competitive. We spent $269.99 for our i7/860 compared to $299.99 ($289.99 today) at Newegg. Also,the Intel X25-M G2 80GB SSD was $349.99 at Newegg ($309.99 today) compared to $269.99 at TankGuys when we placed our orders. So, it does pay to shop around and sometimes the smaller guys might just be able to offer better prices than the large resellers.

    nice to finally see a Bloomfield and a Lynfield in a serious overclock

    hope to see a serious comparison between those 2 soon :)

    if not, can you please tell what type of cooling / voltages you were using and if Bloomfield was harder than Lynfield?

    thanks!

    Why didn't you OC the i5 750?
  • Gary Key - Thursday, September 24, 2009 - link

    I updated the chart to show the i5/750 at 4GHz. We need better cooling for 4.2, the chip will do it, but with the current air cooler, we kept bouncing off the thermal limits and the chip would scale back. In fact, we hit the 90C limit a couple of times in the 4GHz test run which probably explains the slightly lower that expected minimum frame rates.

    I will show the 750 overclocked in my next FSX update. I was hoping to get a couple of decent CPUs though. I have five retail samples, not one of them will go above 4.0~4.1 stable on air cooling. I will drop back to 3.8 and show like clock speeds against the Q9650 and 965BE.

    It's a fair bit of extra work for the Atech staff having to complete a buttload more runs through multiple benchmarks for sure, but I agree. Even if the i5 750 can't be run at an equivalent clockrate, I'd really like to see the inclusion of more oc'd i5 results in Anandtech articles so please do include stuff like i5 750 @3.8GHz vs i7 920/860 @ 4.2GHz. We've seen a couple hardware sites (including Anandtech IIRC) show that there are some issues with Core i7s sometimes performing SLOWER than i5 due to HT not always being as effective as processes running on, two physical cores.

    Plus, given that we can buy i5 for as low as $160 it makes for a killer budget gaming system where we spend the savings on better vid cards. Keep the customers in mind. I'm about to help my neighbor build an i5 750 system packing an ATI 4850 for his kids. Bang for the buck baby.

    Yeah. And if they can get the 860 to run stable at a massive 4.2 it should be possible with the 750 too. Even getting a cooled 920-D0 to 4.2 is no guarantee. Or they can just run them all at 3.8 or 4.0 and spend less time tinkering with voltages and whatnot.

    "SQLSTATE[08004] [1040] Too many connections"

    Doesn't look like Tank Guy's server can handle the plug from AnandTech.
  • Gary Key - Wednesday, September 23, 2009 - link

    I think I killed Ben on that one. :)
  • lyeoh - Thursday, September 24, 2009 - link

    Seems to be back up.

    Maybe they transferred a few SSDs and RAM from stock into their DB servers ;).

    Haven't ordered from them in awhile, going to have to price the wife's new PC there.

    looks like the extra traffic was too much?
