I was just about prepared to get the AMD system but then I saw that the i5 750 killed the AMD sytem by quite a good margin. The system I was going to build was for internet browsing/downloading and video editing/conversion so I wasn't after a flat out gaming rig ... any thoughts on this ... which one shold I go for now ?
 
The Core i5 750 is a better choice for games which use 4 cores and less whereas the Phenom II X6 1055T is much better for software which uses six cores. A lot of video encoding software scales well to six cores.

Look at the benchmarks in the previous thread you started.

Well for Video Editing and Conversion i would imagine the Phenom II x6 will be quite a bit better. But it all depends on how much you do and what programs you do.
 
I do a heck of a lot of video encoding. I use Nero 10, DivX Converter and several others. I am mainly into HD video now so files are large. What turned me off to the AMD solution is that (reportedly) there are very few programs that use the extra cores ... so having them is rather pointless so it seems. I don't know a lot about it so please correct me if I'm wrong ..... so that still leaves me wondering which system to go for ....
 
If so, read a load of the new X6 reviews - for audio and video decoding/encoding they seem faster than the i5 750:

-TechPowerUp (X6 1090T)
-Tom's Hardware (X6 1090T)
-Guru 3D (X6 1090T and X6 1055T)
-Anandtech (X6 1090T and X6 1055T)

It is a bit of a mixed bag, but in the main the X6 beats the i5 750, by a fair margin too. Overclocking the 1055T would also help a lot in the less threaded applications. Also, with more applications moving towards multi-threads, the X6 is only going to get better in comparison to the 750.
 
I see what you mean. It really depends on what you throw at it doesn't it. The main area of use for me is video encoding and the Phenom II X6 1055T works out quite a bit cheaper for performance especially with the overclocked bundle. :D
 
X6 I think would suite your situation better. It's faster at encoding and will do a fine job in games - graphics cards are still the deciding factor as long as you have an adequate CPU.

Plus it's cheaper.
 
Bare in mind that a 1055T overclock from 2.8GHz to 3.6GHz~3.8GHz is only 28~35% overclock, whereas i5 750 overclock from 2.66GHz to 4.0GHz~4.15GHz is 50%~55% overclock. And don't forget architecture wise i5 750 is faster the K10.

Only get Phenom II X6 if you are certain the extra 2 cores will definitely benefit you (or if the extra performance is worth the extra £ to you), otherwise for gaming and general use both the Phenom II X4 and i5 750 would be better choices.

from having both chips the 1090T@4ghz crosses swords with a I7 [email protected] (the max i could get in my Matx case with the I7)and beats it in multi-threaded applications, from what i have seen if your mobo is good enough you will get 3.8 - 4Ghz on a 1055T.
Ive got to say im happy with mine, i never thought the 750 was enough of a step up from a Q9550 i had before.
If you was only gaming i would have said the 750 but if your encoding go with AMD.
Another thing to cost in is the price of mobos my 1090T is on a £60 motherboard at 4Ghz.

Actually, many OcUK forum members are getting their Phenom II X6 1055T processors to between 3.8GHZ to 4GHZ:

Well, I gone through the thread...while I see lots of 1090T overclocked to 3.9-4.0GHz, but for 1055T I can only see Martini1991 managed to overclock his 1055T to 4.0GHz on the expensive £167 Asus Crosshair IV Formula motherboard, so that's hardly 'many' as you said...and lesser board would most likely have a hard time pushing it beyond 3.8GHz.

Unless people are gonna using the CPUs at stock speed...those results are pretty meanless as they are not comparing overclock vs overclock. See the review below for some overclock comparison:
http://www.bit-tech.net/hardware/cpus/2010/04/27/amd-phenom-ii-x6-1090t-black-edition/5
http://www.bit-tech.net/hardware/cpus/2009/09/08/intel-core-i5-and-i7-lynnfield-cpu-review/5

Handbrake H.264 Video Encoding Test results:
i5 [email protected]: 2851
[email protected]: 2391

So assuming the 1090T is at 4.0GHz (3.87GHz+3.4%), it would be around 2472 (2391+3.4%)
1090T at 4.2GHz (4.0GHz+5%), it would be around 2596 (2472+5%)
i5 750 at 4GHz (4.0GHz-5%), it would be around 2708 (2851-5%)

I guess for video encoding, the extra 2 cores on the X6 is still a bit short of compensating for K10's slower architecture when comparing to i7 750. So i5 750 is not only faster for gaming, but also faster for video encoding as well.

I didn't really want this build to carry into a gaming rig as such. I have a i7 9.20 DO 2.66 running a 4 ghz so gaming is no problems at all. I just wanted to get my old system back online and use it for 24/7 internet + video conversion/burning to bluray ... I was going to try and go for integrated graphics card (HD4290) just so that I could keep cost down and because I don't need a stand alone graphics card. So the Phenom II X6 1055 seems like a relatively cheap option if it is going to be able to use all cores and aparently Nero does. Please correct me if I'm wrong.
 
The X6 1055T will do the job fine and you could get one of the 880G or 890GX based computer with an IGP and this will make the build cost less.

Also Bit-tech is an Intel biased site too. You might as well check Guru3D who show the opposite then:

http://www.guru3d.com/article/phenom-ii-x6-1055t-1090t-review/13

The Core i7 860 runs at the same clockspeed as the Phenom II X6 1055T and has HT too.

TBH, if the encoder uses six cores it will run faster on a Phenom II X6 and if does not it will run faster on a Phenom II X4 or Core i5 quad core.

the CPC test isn't the greatest as it uses 2007 tech and programs have been better optimised for extra cores now in fact my Q9550 beats my 6 core CPU and my I7 at max clock beats it by 1000 marks.

The AMD architecture is showing its age clock for clock Intel CPUs are quicker, the 6 Core AMDs compete with mid range Intel CPUs, it all comes down to what you want to buy, the main positive for me in a small case is how cool the AMD CPUs run, at full load on the same cooling 25C cooler :)

For me the best pound/performance can be got from a I7 920 its a beast

edit..i haven't seem bittech or CPC do a decent review of anything..i remember them using 1.5Vcore to get 4ghz on a I7 920 DO, tbh i stopped taking them seriously after that.

so the real answer is "there is no clear winner" ... there seems to be a divided opinion on which is better ... and that's fine ... I respect everybodies point of view. It helps to get both sides of the story. Mind you I'm now still no better of deciding what to go for though :D
