    [h=1]2 Comparativos e antes de mais peço desculpa se estou a postar na secção errada.

    i3 550 4.3ghz vs i7 2600 4.3ghz in games:[/h]


    So as promised earlier I have completed series of benchmarks comparing $120 i3 550 to $320 i7 2600K. Both cpu's have been overclocked to 4.33Ghz. This comparison focuses at gaming performance, and might help some of you decide if it's worth upgrading or not, also those who shop for budget gaming cpu may find this review helpful.

    Now i3 550 is a Dual-core 32nm 1156 socket budget processor. It represents previous generation CPU family based on Nehalem microarchitecture, though it is still widely available on the market. Specs can be found here

    I7 2600K on the other hand is top of the line 1155 socket quad core CPU which is based on most recent Sandy Bridge microarchitecture. Specs can be found here

    Synthetic benchmark results can be called predictable, although as you can see they not always reflect real games performance. However some people may find these results interesting.

    In the end i'd like to say that both cpu's are amazing and i really enjoyed comparing them even though they are in totally different "weight categories". As you can see for 115 dollars i3 550 is a kick ass cpu and I'd take it any day over any sandy bridge dual core (i3 21xx series) due to inability of latter to overclock. I can conclude that clarkdale processors when pushed over 4.0Ghz are not much of a bottleneck even for high end single GPU's like hd6970.

    I also would like to note that ability to overclock differs from chip to chip, however as far as i know when coupled with decent board any clarkdale can reach 4.0ghz. 2600K on the other hand is known as insane overclocker - chips that surpass 5.0ghz are not that rare.

    I hope some of you guys found this comparison helpful. Have a nice overclocking.

    [h=1]i3 540 @ 4,2Ghz w/HTvs i7 920 @4Ghz and 4,2Ghz w/ HT - Gaming Performance[/h]
    Introduction:
    There have been numerous discussion about how different the i3 and i7 perform in games, and whether the more expensive 1366 CPUs are worth it over the much cheaper i3, if you mainly game on your system. There are always many who will say the quad-core i7 will dominate the dual-core i3 and others who will say the i3 can stand up to the i7. I too wondered this, considering I had moved from a Phenom II to an i5-750 to the i3 and not noticed much difference. So I decided to bench off the 2 CPUs against each other to see how they compare in some of todays games.

    Test Systems:
    Intel Core i3-540 @ 4.2Ghz w/ HT
    Gigabyte H55M-UD2H
    Corsair XMS3 4GB @ 1608 8-8-8-20 1T
    Radeon HD 6970 (Cata 11.1a)
    Western Digital Caviar Black (OS)
    Windows 7 Ultimate 64-bit

    Intel Core i7-920 @ 4Ghz and 4.2Ghz w/o HT
    ASUS P6T WS Professional
    Corsair XMS3 4GB @ 1600/1608 8-8-8-20 1T
    Radeon HD 6970 (Cata 11.1a)
    Western Digital Caviar Black (OS)
    Windows 7 Ultimate 64-bit


    Games Tested:
    Battlefield: Bad Company 2 (Operation Aurora - FRAPS)
    Batman: Arkham Asylum (In-game benchmark tool)
    Crysis Warhead (Benchmark tool - Frost)
    Dirt 2 (In-game benchmark tool - London)
    Far Cry 2 (Benchmark tool - Ranch small)
    Grand Theft Auto IV (In-game benchmark tool)
    Just Cause 2 (In-game benchmark tool)
    Lost Planet 2 (In-game benchmark tool - Test B)
    Metro 2033 (Benchmark tool - Frontline)
    Warhammer 40,000: Dawn of War II (In-game benchmark tool)


    Testing Methodology:

    Unlike most reviews, where games are tested at low to medium quality settings to see a (larger) difference in CPU performance, I ran these games at the highest possible settings because as with most other people with similar hardware, they would run the games at the highest (playable) settings they could, so it would be pointless to run on low or medium settings. Click the links for the settings for Lost Planet 2 and GTA IV, as they were not set to maximum because they were unplayable. The settings for Metro 2033 were DX11, V.high quality, AAA and AF 4X with tessellation on and Advanced DoF off. AA was set to highest (where possible) in all other games, aside from the above. All games were run at 1920x1080 resolution. Where FPS is zero, it is because the benchmark tool did not provide minimum fps results.

    Conclusion:
    So there you have it. In most cases the i3 outperforms the i7, however it lags behind in Lost Planet 2, GTA IV and Dawn of War 2 - Games which require more CPU power. While there is not a huge difference (in most cases) here, there could be a bottleneck in Multi-GPU setups, where the CPU would need to do more work, so I suspect the i3 would fall further behind the i7 there although I don't have a pair of one graphics card to test so I can't provide those results. Overall though, these results amazed me because I thought the i7 would beat the i3 by a long way in most of these games, however that is not the case.

    So if you considering moving from an i3 to an i7 and the main thing you do on your system is game then it may not be worth it to you, or if you are thinking of moving from an older generation of CPUs but are constricted by a budget, then the i3 is great once overclocked. Of course you could always upgrade for "future-proofing", especially now that an i7 setup can be had for a good price. In the end the i7 is still a better buy if you have the money for it but if you don't and are thinking of saving up but need a desperate upgrade, the i3 is something else you can consider for a lot less that will give you comparable performance in most of the games.

    Thanks for reading and i appreciate any feedback.

    Já tinha lido. É um artigo com algum tempo.

    E por acaso sempre me questionei:

    Valerá a pena comprar um i3 SB bloqueado quando um i3 1st gen, apesar de ter um desempenho inferior por clock, faz OC até aos 4.0GHz, 4.2GHz?

    Também podemos pôr a questão ao contrário:

    A maior performance que o i3 SB tem por clock, chega para bater um i3 1st gen com OC a 4.0 ou 4.2Ghz?

    De resto, concluí-se que os dual cores com HT da INTEL são muito bons. O consumidor consciente, que queira guardar algum, e que não sofra da magoa psicológica de não ter um quad, fica bem servido com um i3.

    Quem diria o i3 550 com bom OC joga-se tão bem como o i7 2600k, e não fica nada capado, nota-se diferença quando usa-se mais cores...de resto grande performance com OC.

    É verdade e eu que já pensava que o meu i5 750 estava a ficar fraco nos jogos...

    mais depressa mudas duas ou 3 xs de grafica , mantendo esse processador

    Será então seguro dizer que um i3 550 com bom overclock ultrapassa em performance um mero i3 2100?
     
  7. rodrigox

    rodrigox Banido

    Talvez. Um i3 550 a 4Ghz seguramente será superior a um i3 2100, dependendo dos jogos, mas em aplicações seguramente será superior.

    E para o levar aos 4.3 Ghz é necessário gastar muito numa boa MB?

    Ele usou uma board com chipset H55 que por sinal são boards mais baratas que as P55.

    Eu tenho um i3 550 bem queria fazer um O.C nele e tenho temps boas para fazê-lo, mas não percebo nada de nada de O.C e tenho receio de queimá-lo.

    Podes começar por desativar o Turbo Boost e o Speed Step. Depois podes começar com vcore tipo 1,2v. A partir dai poes o multi a 20 e vais aumentado o BCLK. Tens de ter atenção às memórias que presumo que estejam a 1333Mhz com multi de 10 (133x10). Tenta não afastar as rams muito dos 1333mhz jogando com o BCLK. Isto porque primeiro queres ver até onde o CPU vai. Só te posso sugerir alguma coisa se souber até onde vai esse multi... O multi maximo que podes ir é de quanto?

    O multiplier? hummm não sei, vou ver se descubro.

    Estou um bocado de pé atrás, eu não percebo nada de overclocking e tenho receio de mexer nas voltagens e ram.
    A minha ram é de 1333mhz Mexendo no blck sei que em baixo não me posso afastar muito dos 1333mhz, mas que valor pode atingir a freq da memoria?

    e aqui tenho muitas duvidas
    cpu voltage Mode - Auto (ponho manual)
    Fixed voltage - auto (1.2?)
    IMC voltage - auto
    dch voltage - auto
    auto psi - auto

    cpu ratio ponho 20~21?

    uma ajudinha só para eu começar nisto porque nunca fiz oc.
