    So I was looking around 3dmark11's (graphics) scores to see what other people have got at my configuration and while doing so I decided to check out the intel scores

    It was surprising... because I thought the graphics score didnt really matter that much on the CPU (it does a bit but not to this extent)

    i5-2500k @ 4.8ghz and 7850 @ 1.225/1.400 ghz
    Graphics score: 13815
    http://www.3dmark.com/3dm11/5950367

    To my surprise a two core i3 had a better graphics score too...

    i3-3220 @ 3.2ghz and 7870 @ 1.200/1.350 ghz
    Graphics score: 7595
    http://www.3dmark.com/3dm11/5976370

    In contrast the AMD scores are around the 8k mark. A 6300@5Ghz hits the 7988 mark (but ofcourse the 6300's physics scores are much much higher).

    8320 @ 4,508 MHz and 7850 @ 1,268 / 1,516 MHz
    Graphics score: 8160
    http://www.3dmark.com/3dm11/5835229

    The AMD processors cant even get past the 10k mark... the fps difference is huge too. :mad:

    I see alot of people saying, well 6300 wont bottleneck ur 7850 or heck even the 8350 wont. But it isnt true, from those links it seems the amd cpu is too slow for the card (ie not making the most out of it)

    Nothing new or am i interpreting it wrong? (I was using the 3dmark search feature to filter results (GPU : 1 and valid scores)

    Edit: It seems the 3DMark database is not reliable for finding scores (system configurations are buggy)

    chek for gameplay of ppl on youtube...,thhis is just one benchmark and doesnt represent nothing!!
    fx 6300 cpu is great for gaming...and it half price of i5!! and it will not botleneck hd 7870 in no way!!

    the one with with the 2500k is weird almost like crossfire ..it cant be right.

    Thats what I thought too, the first reaction was some kinda hack, but idk.

    The second highest score (2500k, 7850, 1 gpu, valid) shows gfx scores around the 9k mark.

    If I go to the 3570k, for eg this guy, he still gets a 10k score.

    I think it has to do with memory transfer rates too? Intel chips have rates in 20k.. AMD ones have a hard time reaching that number.

    Okay, I checked the hwbot submissions and the highest in that config had a score of 9064.

    http://hwbot.org/submission/2359205_eraldofreitas_3dmark11___performance_radeon_hd_7850_8612_marks

    That 3dMark database is bugged, most likely reporting 2x cards as 1 (or someone is editing the files to change the results/detection).

    Bottlenecking does occur a bit, but these scores make more sense:


    Highest score - 9800 (1k usd CPU)
    http://img.hwbot.org/u13834/image_id_878116.jpeg

    With i5-2500k - 9064
    http://img.hwbot.org/u45028/image_id_924036.png

    With FX-8350 - 8515

    You're interpretting it wrong. Do you base all your decisions on 3D mark 2011?


    The test rigs are NOT the same.

    Look carefully at the specification. The Intel rig has better hardware!!!!!

    i5 rig has 16GB of RAM and 4GB of video Memory.
    The FX rig has only 8GB of RAM and 2GB of video memory

    You don't find many 7850s with 4GB of video memory, so it could be a crossfire configuration on the Intel rig too.

    and that's a oc 7950; stock 7850's should be in the 6k range gpu score no mater the cpu.

    Its crossfire for sure that top score with the i5 as thats about what i get with my main rig at stock settings.

    Im trying to pick a popular benchmark which has lots of results recorded to i can base the analysis on that. I dont think system memory above 4gb affects scores in the 3dmark11 performance setting (neither does video memory >2gb)

    Bleh, i just did the search again, and your right, its showing 7900 series even though I put the 7850 in the search criteria.

    This is more accurate for the Intel i5-2500k:

    http://img.hwbot.org/u43201/image_id_841549.jpeg

    But only 6817? lol.

    1100T for comparison - http://img.hwbot.org/u43829/image_id_866849.png (feeling a bit better now :D)

    As I said you don't find many 7850s with 4GB of video memory, so it could be a crossfire configuration on the Intel rig too. Two GPUs will affect the score significantly.


    The scores of the 1100T (4.2GHz) and i5-2500k (5.3Ghz) are almost the same. Only 16 points separate the two CPUs.

    Intel needed a 1.1Ghz overclock for only 16 points more????

    That 11k score with just one HD7850 looks awfully suspect.......even HD7970's or GTX680's have to be OC'ed with an OC'ed i5/i7 to rate that kind of score. Here's my FX8350 @4.45ghz + 2x GTX670 score.....

    The Vishera may not bench as well as an Intel equivalent in synthetic benchmarks, but they're plenty fast enough for gaming.....and that's where it should count the most.:rockout:

    I think youre interpreting this wrong because look at the scores for the same CPU/GPU the range of scores is absolutely huge. ive had the exact same set up/clocks as someone but yet the scores was hugely varied. so its obvious software, other components etc count. not just cpu/gpu. but when I compare to intel chips they seem to have greater scores, not sure why tbh. maybe someone that fully understands can explain. and the max score on 3dmark 11 I can get is 7000. and that's a 7950, but the physics certainly fails. oh and I run 4gb and get a better score than when I run 8gb or 12gb (not much just several more points etc)

    No but having two GPUs does, which is what I was also trying to point out.

    I think ive figured out the issue:

    So people with multi-GPU systems were disabling SystemInfo, and so their scores are being reported in the single card category.

    Messed up database.

    Yes, your right. I didnt think of it that way ^^

    I have 3570k + 7850. I score about 8k.

    not a 7850 but a HD7950 / AMD FX-8350

    but why u keep that grip to 3DMark 2011 as reference ?
