How is the performance of the current core I7 versus the AMD FX, 8 core chips? Any comments appreciated.
Its single threaded performance is not that good compared to Intel Sandy Bridge.
I would be sticking with Intel for SolidWorks systems.
Depends on where you get your information...................
Bottom line, the AMD's will be less expensive than the Intel's.....and give you similar performance.
It looks like the single core performance is still lacking, and at a steep price. the Core i7-2600K is now $280 at MicroCenter, and much faster for SolidWorks (probably). The AMD FX-8150 is $270, so for that extra $10 you get amazing performance increases with the Intel Chip.
- Note that the first test is for software that can handle the multiple cores, and the AMD is still slower. The later tests all run on a single core, and the Intel chips destroy the AMDs. The Lame test is probably closest to SolidWorks.
For a SolidWorks system, get an Intel Core i7-2600K (or non-K version and save $30). $280
For a home computer, get an Intel Core i5-2500K and overclock it. $210
If you're counting your pennies, get the AMD Phenom II Black, 3.2 Ghz for $170
Don't spend $270 on the AMD Bulldozer. The bulldozer sounds like it will be a Best Buy special "Come look at this computer, it has EIGHT CORES!@# That's twice as many as the Intel Core i5!!!!ONE!!!"
In photorendering a high res image I noticed all 4 cores were docked to 100%, in this case would the 8 cores be beneficial? and it's obvious you're an Intel fan.
Thanks for the comment.
Yes. for Photorendering 8 cores would help. In fact, for a photorendering system I suggest the Core i7-990X (6 cores plus hyperthreading, which is very beneficial for PhotoView). But that does carry a steep price tag ($900-1,000 or so). Or even the Xeon 2 processor equivalent if you are serious. The hyperthreading brings it up to 12 virtual cores, and it screams (the virtual cores add about 30-40% of a real additional core).
But SolidWorks modeling doesn't use multiple cores, so then the question is how often do you actually do rendering? Even if it's once a week for a couple hours, I'd still go for the single core performance. If you run overnight animation renderings and it is chugging all the time, then I would look into the higher core counts. If you do that, though, I would think you could justify the i7-990X.
Another interesting comparison is a 2 up Core i7-2600K compared with a single Core i7-990X. They are comparible, and then with the 2up you get 8 real cores plus hyperthreading.
And I'm a fan of facts. I've owned AMD, Cyrix (http://en.wikipedia.org/wiki/Cyrix_6x86), and Intel chips. The day AMD (or anyone else) makes a chip faster than an Intel chip, I will endorse it. Or if someone comes up with a way to make the $/flop a better value. The Phenom II's are cheap, and a good CPU for checking email on a budget, but I think the Core i3 and i5's are still a better $/flop value.
