Intel i5-650 vs Phenom II X6 1055T vs Intel i5-760

for me this is a question of more cores better?

I often have multiple applications running, msn, steam, internet, etc

but it is of course not hard to close these to run games.

question is what would be the best processor to go for? I first found the AMD phenom II X6 1055T and thought it looked pretty neat being a six core processor, but then was advised to go intel by a friend

but I have compared AMD phenom II X6 1105T to intel's 4 core processor i5-760 and they looked fairly similar.

But then I looked at this post in this thread.

i5-750.

The 1055 is a dud. AMD Phenom II X6 1055T Overclocking - X-bit labs. It really looks bad when stacked up against Intel's 6 core: Six Cores from AMD: AMD Phenom II X6 1090T Black Edition and Phenom II X6 1055T CPU Review (page 6) - X-bit labs


Yes, the 650 has hyper-threading, but games don't take advantage of that. There just aren't many, or any titles that can take advantage of hyper-threading, so it becomes a moot feature. Game review of the i5-750 vs i7-975 Extreme: Intel Core i7-975 EE and Core i5-750 in Contemporary Games - X-bit labs The difference, which is incredibly minor, is due to the platform and clock speeds of the two chips.

how is AMD's phenom II X6 1105T so bad as compared to intel's i5?

The game has changed now with Intel's Sandy Bridge. Wait a few weeks and see how that plays out. It may end up taking the performance per dollar crown from AMD. A few weeks ago I'd have said to stay with a decent S775 platform or upgrade anything else to DDR3, AMD Phenom II X2 555 Black Edition rev C3 and get at least 4GHz from 3.2 and two extra cores for $90 flat. If the Intel Core i5-2500K comes down in price any it may actually have better performance potential as well as better platform longevity.

Welcome to Seven Forums rocoyo. I'm a fan of the i5 750, and by all measures, the i5 760 is even better. Generally, I'd say the i5 760.

I also have a i5-750 and it is great, I think the i5-760 is a little better.

As baarod mentioned, the Sandy Bridge i5-2500K is looking pretty amazing and out of the gate it's price is only a little more than the i5-760 with more performance.

[rocoyo]

lol thanks for all the awesome reply's, the sandy bridge CPUs do look pretty awesome.

yeah US prices don't mean much to me as I live in new zealand

I need a brand new computer for my studying/gaming

here is what i have so far

also going to buy a few fans to stick in my case

just putting that up in case I made a mistake x.x

You'll need a motherboard with a 1155 socket for that i5 2500 Sandy Bridge CPU.

The rest looks prety good, I would get at least a 650w PSU.

Intel i5-650 vs Phenom II X6 1055T vs Intel i5-760

for me this is a question of more cores better?

More cores are only better if you do ALOT of tasks that benefit from the multithreading. And of course, the app itself needs to be optimized for it.

For the large majority of things, gaming included, theres not much benefit.

Clock for clock, Intel is typically much faster.
So fewer, faster cores over more slower cores would be the better choice IMHO.

 

[pparks1]

The number of cores only affects applications that take advantage of multiple cores efficiently. Games often don't, thus you are better off with faster clock speeds.

If I were buying today, I would consider nothing but the new Sandy Bridge Intels. They are dirt cheap $180-$300 and outperform everything out there. In fact, the Core i7 Sandy Bridge is right up there with the $1,000 Core i7-980X.

I would do the Core i5-2500K if you want to save a few bucks, it's $224.

Otherwise, spend the $299 and get the Core i7-2600K,

The link that you provided was to the 2600, which has a locked multiplier.

The 2600k is a bit more expensive:

($330).

 

[pparks1]

Hey, thanks for the correction. Sorry for linking to the right thing. So, it's $299 with a locked multiplier and $329 for an unlocked multiplier for those who must overclock...or at least have the option.

alright look better?

 

[Dave76]

Yep, that's the right mobo and socket for the Sandy Bridge CPU.

Did you check the motherboard website for the compatible RAM list?
Good thing to check to make sure you don't have RAM problems.

 

[diehrd]

I would suggest a 256 bit video card , as long as your building new you might as well get the latest available technology.

 

[rocoyo]

i can't afford a 256-bit gfx card at the moment as it's quite a sudden jump in price, I suppose it will have to be the first thing I upgrade then

 

[rocoyo]

so the 1155 socket motherboards got recalled, is the issue worth not buying sandy bridge at all?

can get a motherboard if eed be

~rocoyo

 

[Dave76]

I would wait until the motherboards with the new chipsets are available.

Looks like it will be in April.

 

[rocoyo]

yeah they say end of april, so looks like i will be getting an intel i5 760 with a 1156 socket till then.

 

[Dave76]

The new i5 (2500) and i7 takes a 1155 socket.

The i5 760 takes a 1156 socket, they are not interchangable.

 

[rocoyo]

oh yeah a typo

just curious

what is it that makes intel processors faster than AMD processors?

the AMD Phenom II X6 1090T has a frequency of 3.2GHz and is outdone by the intel i5 760 in THIS bench test.
