    Talking Core i5 750 + P55 UD3, benchmarks incoming!

    I got my hands ony a Gigabyte P55-UD3 and a Core i5 750, this time around they're not only being sold early in Asia but also here in Germany :)




    I'm working on a review right now, for comparison I've got a Q9550, an E8500, a Core i7 920 as well as a few others that I can get a hold of like the Q8300 and E7400. No current AMD CPUs unfortunately :(

    I'll be mostly focussing on gaming benchmarks, but I might throw in some productivity benchmarks after the gaming part is finished.

    Right now I'm planning to bench the following games:
    • Far Cry 2 (using the built-in benchmark tool)
    • Crysis Warhead (Using the benchmarkt tool)
    • GTA4 (not sure wheter to use the included benchmark or a save game; Btw, does anyone know how I can trasfer my saved games to another PC?)
    • Supreme Commander (built in benchmark using /map perftest)
    • Resident Evil Demo benchmark


    I also have the following games, but I'm unsure about which ones to use. Using all of them would take too much time. If you think one of the
    • World In Conflict (the built-in benchmark is a little inconsistent, benching intor sequences doesn't make much sense either though I think)
    • Company of Heroes (I don't know how much the built-in benchmark#s performance correlates to actual in-game performance)
    • Race Driver: Grid (kind of pain to benchmark since you actually need to play it if you don't just use the fist 10 seconds at the start)
    • Call of Juarez (seems like a decent DX10 Benchmark, not many people play it though I think)
    • Assasin's Creed (also kind of a pain to benchmark)
    • Call of Duty 4 (a little old)


    I'll be benching at 1680x1050. While lower resolutions show bigger differences I actually want to bench using a realistic real-life scenario, and not go the 800x600 route. 800x600 shows the difference between CPUs to be greater than the actual difference at 1680x1050 or 1920x1200 will be since, the last two scenarios also depend on the GPU, while 800x600 is never GPU limited if you use a high-end video card.

    At first I'll bench with a GTX 295 but I plan on looking at video card scaling as well and use a GTX 260 Core216, a 4870 512MB and a 4830 maybe along with different overclocks of the CPU.

    If you have any input on testing methods or have any benchmark requests please tell me, I'm relatively new at this :)

    Can you clear something up? Does this kind of board not have triple channel memory?

    The Lynnfield based CPUs for the LGA1156 socket "only" support dual channel. That's not much of a big deal though, especially for gamers, since reviews have shown that running a LGA1366 Core i7 in dual channel mode doesn't decrease performance much compared to triple channel mode.

    The Lynnfield CPUs (Core i5 750, Core i7 860, Core i7 870) are supposed to be officially released on Sept. 6th btw, but they've gone of sale early in some parts of the world.

    Any chance you can get another 4870 for crossfire. It just seems that your chpsen CPU will have plenty of muscle to make the GPU the limiting factor, especially as you're running 1680x1050. Crossfire and SLI rely much more on having enough data being fed to them and would give clear performance changes as you over clock the system.

    Moving up in res to say 1920x1200 would confirm that CF/SLI can only output good FPS with a CPU powerful enough. In the highest res testing I'd expect CPU power to make more difference than some think.

    You must have missed the GTX 295 part

    I can see if I can get another 4870 though anyway, my brother is about to buy a new video card atm anyway, maybe I can push him to get a 4870 512MB^^

    Benching as we speak now. I tested configurations and stuff yesterday to make sure I get consistent results. First results will be in in a few hours.

    I'm thinking the Kayapo tribe will have theirs before we do.

    Yes, sorry I did miss the GTX 295 at the start of that sentence.

    If you could get another ATI card it'd be interesting to see how CF behaves on the board. As you know you could use a 4890 if you can't find another 4870. The 4890 will just simply wait for the slower card or can be down-clocked. A 4850 will also work but again would be performance limited, this time by the 4850.

    Would you be willing to do a special request benchmark file of Far Cry 2? I can upload it here. It's the config I play ATM with a balance of looks over FPS. DX9 with just 2xaa and a mix of ultra and low (vegitation is on low) settings. I took a while working out what settings made the bigest FPS increase for the smallest visual compromise possible. If you do test using it, only doing multi GPU is fine. Would be nice to know how much it will potentially scale.

    The file gives an average of ~63 FPS with a minimum of 48 FPS. The minimum hardly ever manefests in real game play, only on the benchies really. I use Ranch Small mainly.

    I do have a 4850 I can use as well. I have absolutely no experience with CF/SLI though, so I'll need to play around a bit.
    I'll also test your custom settings, but I want to finish the regular part first. Today I want to finish GTX295/GTX260/HD4830 with the i5 750 and Q9550. I should also be able do a little overclocking and see how the i5 750 does. I only have a Cooler Master Hyper TX3 w/ a 92mm fan though for 1156, I'm too busy/lazy to build a loop out of my "spare" watercooling parts. If it stays as cool as I expect it should do quite fine with that cooler already though.

    I understand. You must try what you have planned first. I'm most greatful that you're going to try my config, and am in no hurry. Thank you.

    If you wanted, I am doing a similar thread soon on Gigabyte Crossfire and how Core 2 frequencies make a difference with two hungry GPU "mouths" to feed.

    I'm obviously not going to post any of that in your thread, as it's not quite the same. However If I can find the same games and also do my own testing I would be honored if you wanted to link to it in the relevant section of your postings. Visa Versa, If I could give yours a mention and link kind of in a "And here's what happens using a more moddern architecture CPU" way, that would be amazing.

    I'm not sure when my set of posts will be ready. I have to register with an imaging host first. I'm also doing a little section on VGA cooling with photos. I also have to wait until one of my 4850's is returned from RMA before doing the Crossfire portion. Basically my guide will briefly cover:

    VGA cooling options (temps vs noise etc)
    EP45-UD3 cooler compatibility (should hold true for all boards with 2 clear slots between PCIe slots)
    RAM influences in Vantage and Far Cry 2 (4-4-4-12 @DDR-800, 5-5-5-15 @ DDR-800 and 5-5-5-12 @ DDR-1066
    A set of single benches, maybe not the settings I use to play but something to tax the config at stock GPU and a CPU of 2.8GHz, ~3.2GHz and max OC of 3.9GHz with DDR-1093.
    Same benches with CF enabled and same CPU speeds tested.
    A max performance CF session with max CPU OC and a GPU at around 750/2200 (as long as the replacement card manages what the current new one does.

    If you did want to directly compare anything to my results then a 4850 as you know will CF with a 4870/4890 and restrict the more powerful card. I'm not trying to suggest how you test, merely just if you have time, perhaps as an "also ran" at the end.

    Cheers.
