Intel Core i7 920 vs Intel Core 2 Quad Q9550

[nista]

hi,
I'm looking to build computer,What should I choose for gaming? if the new Intel Core i7 920 is better than the Intel Core 2 Quad Q9550 . But, the Q9550 is 2.83 Ghz and the i7 is 2.66 Ghz. Which one do you think is faster?

hi,
there is an "economic" consideration: do you currently have an LGA775 motherboard or an X58 motherboard? do you have DDR2 RAM or 3 sticks of DDR3 for triple channel?

if youre going to buy a whole new system, then yes you could go with i7. but if you already have a P35 and up motherboard with good DDR2 RAM i would go for the Q9550. if money is no object get a Core i7 Extreme 965!

Overall the Core i7 920 outperforms the Q9550, however it really comes down to whehter or not you want to re-use your DDR2 RAM, or want to buy DDR3 RAM and a new motherboard ($250+).

[SecRecy]

Larger cache better for games, but OP doing encoding etc, so an o/ced i7 920 will do a MUCH BETTER job.well of course i7 is going to be better.
just up to you as to whether you want to spend the amount...
DDR3 on the first isn't justified?

I got a P35 and up motherboard with good 8 gig DDR2 RAM .. i need to know which is better the i7 or the qd2.8 ... like money is no object
so which one would u people reccomand

[Russell]

I think you should go for i7 , as Sebastian.j said

Overall the Core i7 920 outperforms the Q9550

It is the best you can get for your P35

[derrickstubbing]

Great thanks.. thats what i be getting Mon.. atm i got quad 2.4 still really good but want something better

[StanDP.]

No way, go for the Core 2 QUAD 3GHZ at tiger direct it performs better and full load (downloading at 160kbs 4 torrent files, backing up system c: drive 255GB, and burning a DVD Movie etc.) doing all this only put the load of this processor at 14-15% usage HAHA it kicks butt man!

did you know that i7 has 8 cores but quad has only 4

know tell me if quad is faster than i7

The Cores you are talking about will do no good if the operating frequency and cache is less... The thing is, Core operate in parallel, and if you have a 32bit processor, you use all the cores at 32 bit only... you still need a good amount of memory and cache for it to function properly... But here, sticking to the topic, Core i7 is performance monster...

what are you talking about about 32 bit processer

we are in new age i thought we are working with 64 bit prossing

if you can aford i7 go for it

The Level 3 cache of Nehalem is described as being ‘inclusive’, meaning that it holds the data of all the Level 2 caches. This means that if a core needs to fetch data, and it doesn’t find it in the Level 3 cache, it can be confident that the most up-to-date version of that data is held in system memory and fetch straight from there. If the Level 3 cache wasn’t inclusive, the core would first have to look at the cache of the other three cores to ensure that none of them had a more recent version of the data it needs. An inclusive cache is therefore said by Intel to be more efficient than an ‘exclusive’ cache design, even if it does mean that 1MB of Nehalem’s 8MB Level 3 cache is taken up by storing a copy of the 256KB Level 2 cache inside each processing core, again this translates into a performance gain over Intels previous designs.

Intel has integrated the memory controller onto the Nehalem CPU die rather than having it be part of the Northbridge on the motherboard. It's achieved this by modularising the design of the CPU. The seperate processing cores and caches are linked to the onboard memory controller via a new bus standard called QuickPath (sometimes called QPI, short for QuickPath Interconnect). As QuickPath replaces the Frontside Bus (FSB) and Northbridge combo, it also takes over the role of allowing the CPU to connect to other system components, busses and controllers such as the PCI Express controller and DDR3 memory.

The last big news about Nehalem is that it uses Hyper-Threading. This technology works just as it did with the Pentium 4, using spare resources of a processing core to try to execute a second process thread. This means that a quad-core Nehalem processor can accept and attempt to process eight threads simultaneously, making it even more massively parallel than the current Core 2 Quad CPUs.

64bit processors, yes these exists, All the dual core, core2duo, quad and i7 are 64bit processors. But suppose you are using Windows XP Pro 32bit, Then what are you gonna do with the remaining 32bit of each cores? shove it somewhere??

i thought nista was bulding a new comp so if is spending money he did not say he was going to run a old 32bit win
that he is going for brand new top of range cpu etc. Etc so I thought he must have sense to get 64 bit window
