i want to buy cpu and my heay program is gaming,autocad and heavy calculation and video....
so i have 320$ for cpu.and i am between i7 930 and 1090t
in froum i read that when you overclock to cpu i 7 930 is better than 1090t.is it true?

from the benchmarks i have seen the 1090t had better score in video and music infact in music it out scored 1200$ intel chip but its hard to say for what u r doing i go for the 1090t u have to take benchmarks with a grain of salt for as the 1090t did better in some benchmarks the i7 930 did better in others so it up to u what u need the cpu for and how much better it does those tasks

just read somemore benchmarks and reviews and most r saying that the 1090t tops the i7 930 in most benchmarks and is very close to the i7 975 but still readding lol

There is no evidence to support that an overclocked 930 is better than an overclocked 1090T. In fact, considering that a 1090T beats the i7 975 EE in a lot of benchmarks, it is much more likely that clock for clock, the X6 is faster albeit by not a huge margin.

so you tell me that if i buy 1090t 309$,like intel 800 969$.but in gaming 1090t is not good as phenom ii965 or 930.have any link that 1090t beat 975ee?
 


Its a tradeoff. The I7 930 is a stronger gaming chip, 1090t is better for encoding. Your doing both, but it looks to me like more encoding. I would go 1090t for sure.

As for your overclocking question, it depends. IF you can overclock them both to the same speed, say 4 GHZ, the 930 would be a little faster as it does a little more work per clock cycle. But the 1090t has an unlocked multiplier which makes for an easier overclock.

Multiplier overclocking is a much preferred route in my view. It also puts less stress on other components like board chipsets and memory since you can leave the MB setting at stock.

Finally, AMD is better at keeping an upgrade path. For example, in a year you decide to upgrade your cpu, but wish to continue using your other components. AMD is far more likely to have a faster, drop in, replacement available than Intel. A big advantage down the line.

Let's be clear jennyh the 1090t lose more benchmarks then it win against the i7 975EE and the i7 930 can be overclocked to the same clock speed
as the i7 975 and higher, so no the 1090t will not just beat i7 930 running at the same clock speed.

I seriously doubt that.

i ask to say your reason with document(link,benchmark)
i am a civil engineer now you know that what exactly i want.
thanks every body

You do realise the i7 975 EE is higher clocked than the 1090T right? :pfff:

My point still remain the same it lose more then it wins.

No your point was that clock for clock the i7 930 would beat the 1090T.

What actually will happen is, the 930 will win the benchmarks it always won in, and the X6 will win the benchmarks it always won in.

It is well known that the 930 is a poor overclocker comparitively btw.
 


As you can tell by my name, we're in the same field .... I have yet to see an AutoCAD box with an AMD processor.

Thank you for proving my point to blindside jenny.
point in fact the i7 930 is the comp. for the 1090t
and holds up pretty damn good, 4 cores is giving
6 cores a problem.

Try to imagine this at 4ghz and you'll get the point. Real cores > HT *so long as the software is good enough*. Thuban is totally destroying the i7's here because the software is good. Any time the software is good, this will occur. Why? Because Thuban is faster, it really is that simple.

Your kidding right ? You have to give me a link where that was observed. Compared to what, the 920? They achieve a 50% o/c by just about anyone.

Made this post in the other thread, but its more relevant here because the question posed here.

Strange as it might seem, but a quad-core CPU on Intel Nehalem microarchitecture with Hyper-Threading technology overclocked to 4.0 GHz almost always outperforms six-core CPU from AMD. At the same time I can’t say that Thuban’s frequency potential is higher that of Core i7 CPUs on Lynnfield and Bloomfield cores. Therefore, there is only one possible conclusion here: microarchitecture of contemporary Intel processors makes them faster than AMD processors working at the same clock frequency. And even a 1.5 times increase in the number of computational cores can’t make up for that. That is why we again arrive to the same conclusion that AMD’s only weapon in the battle for consumers is their pricing policy.

No not all of the benchmarks support 6 cores.

If they did, Thuban would be miles ahead. This is where it appears to be falling behind - in poorly threaded apps, but the reality is it's the software that isn't optimised for the cpu. The cpu itself is clearly superior so long as the software is up to it.

Notty all I see is a bunch of synthetics except for a couple (cinebench, x264) and they are both almost identical - one win each.

What about my pov ray benchmark? Or this BC2 one where Thuban takes apart all the intels, especially the i5 750 which loses by over 10% even when clocked to 4.3ghz vs the stock 1090T? How does the 1090T at stock beat Gulftown at 4.2ghz?

yes in video and rendering amd is the best in price/performance.but in another field.i tell you that i am a fan of amd.but i want to choose intellectual answer!!so tell me the best choice without prejudice.i adopt you jennyh
