i3 vs i7 - Gaming Performance [updated] - Page 15

post #141 of 195
I have some AIDA64 benchmark reports fo my i3 560 @ 4.25 vs my 980x @ 3.86. It was kind of interesting, The i3 with a higher clock was not as far off as I would have guessed. I will post them up when I'm at my home pc and I get a chance.

I think it's a fantastic review, but there is a problem. It seems that in most cases you hit a GPU bottleneck and not a CPU one, and so if you really want to see the gaming performance of a CPU you should have run the tests at 800x600, the lowest resolutions, so that you wouldn't hit a GPU bottleneck, but instead you would hit a CPU bottleneck.
I wasn't looking for a CPU bottleneck. The point wasn't to see how much faster the i7 is, because I would have set everything to the lowest setting possible as you suggest, but the point was to see how much faster it is in modern games at the settings people use. If you missed this bit in the OP, i'll quote it again.

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 [with a modern graphics card].

So in conclusion, what logical explenation is there for the i3 to be faster then the i7 in a benchmark with the same clockspeed? I dont get why it is faster...

I understand where you're coming from, but what if someone has a system with 2x6950 or more. Then, the CPU will bottleneck the PC's performance.

Since you only used one GPU, most gaming bottlenecks will come from the GPU, but what if you had more GPUs or decided to get another 6950 later. Then the CPU will bottleneck your PC and so some of your performance will be lost due to that.

That is the whole point of buying an i7. To be sure that the CPU will never bottleneck your system in any application, no matter how many GPUs you have.

i7 are over kill , that's why we like them. Note this is overclock.net, I fold and i7 is great for that, To bad my 580gtx gets more ppd then my i7 now >{

i3 have their place too, they are much more fun to overclock than an i7.

Don't know. Architecturally, the i7 should be superior but the difference may have been because the QPI link speed was a lot higher on the i3, running at around 8.8Ghz i think, over the i7 which was at 7.2 or 7.4Ghz If i'm not mistaken.

You are right there, however not always will the i3 bottleneck. To a certain extent, yes, but there are some games which will still be GPU bound. Had I a second GPU, I would have tested but I didn't. But most people only run one GPU so it doesn't matter all too much, and those who can afford 2 high-end GPUs should be able to afford an i7, or similarly powerful Quad or Hexa-core CPU. This comparison was mainly for those who may be looking to upgrade from older sockets to something more recent and their main purpose was gaming, or those who were on the i3 and were wondering whether a jump to X58 would provide more performance.

Yea they are more fun.

This review is awesome - however you have to remember that for some odd reason most games still prefer dual core.

Most games aren't or weren't coded with 4C CPUs in mind (until now), and considering these CPUs were running at pretty high speeds, the chance of a CPU bottleneck was even smaller. I should really have tested more poor console ports such as Splinter Cell: Conviction, but that game didn't want to play nice with FRAPS.
