Any out yet? really want to see how both compare for latest games....

Disappointed in I5 750 price, having a play around on one or two sites with custom machines.

Save around £100-£150 on a I7 build(but I7 has 6gb memory, I5 only 4gb), which is not bad i guess for us people just wanting a system for gaming. A I5 750 comes too around £880 with a 4890 inside it. Same AMD machine with 955 is around £820.

£60 is big difference for both which are suppose to perform near enough same, just want game reviews to back this up. If true then unless I5 comes down over enxt 4 weeks, then either a I7 920 or AMD 955 is only option at prices.

As i say bit disappointed.

Obviously would not be getting it with a 4890, but new dx11 card, so prices also go up by a fair bit,
 
jst give it a chance,prices wil drop soon enough,and as i can see i7 920 lag behind AMD 955 in games execpt few, and i5 750 is slower thn i7 920 in games but a bit faster in encoding,so do the math ,but still cant say anything untill i see the real benchies
 
Well taking a look at gaming performance Phenom II 955 vs I7 core 920, then the AMD looks cracking value.

They look very decent, considering a AMD system can come in £200-£300 less than I7. Be interesting how the I5 looks and compares;)

one of the reviews i was just reading put the i15 above the 920 in games but in general still opted for the 920

I think people were hoping that i5's were going to be i7 killers, they're not !

Did they? :confused:

Most people expected them to be nearly identical in games and worse at anything that would see an advantage of hyper threading, which is exactly what they are proving to be.
 
There were a few people claiming they were going to be better than i920 but that was down to ignorance more than anything. :p

i5 is rather Intel's answer to Phenom II dominating the middle-high range of the market, nobody really wanted to invest in S775 quads anymore and LGA1366 is like super-high range.

Why does the i7 get 4870 crossfire whilst the AMD gets 4890 crossfire ?
to nock the i7 down a whole bunch of notches in what are GPU limited apps ?
to make those benchmarks effectively useless ?
:rolleyes:

Are you including screen/keyboard/mouse in that ?
You can do an i7 system for £750. With a 4890.

Because then those two set ups would cost the same.
 
Thats still pointless, if you were working to such a budget then the wise option would be to buy one GTX275/4890 and add another at a later date.
For all comparitive reasons those benchmarks are pointless.
 
Well I read Anandtech's review of the new socket 1156 I5 and I7 and also The Tech Report's...and the I5 750 actually beat the I7 920 on quite a few tests, only when the power of hyperthreading and or triple channel memory could be utilised did the 920 outgun the I5 750. Gaming seems to be an area where the new Lynfields are extremely strong, their excellent implementation of Turbo boost is what takes them past the I7 920 much of the time it would seem.

Then I read Bit Tech's review which was slightly less enthusiastic about the Lynfield cpu's, but the key differance was that Bit Tech were doing a lot of overclocking, and it would seem once Turbo boost is disabled and the chips are pushed to the maximum, which seems to be around about 4Ghz for all of them, inlcuding the Bloodfield I7 920, then the later takes back it's crown.

The power consumption is lower than the Bloodfield or AMD Phenom II based platforms though, and the slowest Lynfield. the I5 750 is faster than the fastest Phenom II in most tasks thrown at them, making the Phenom II seem a tad over-priced right now.

Lynfield has a very good box of tricks and seems to be a very refined cpu, a refinement of the Nehalem architecture really. But, if you are overclocking to the max, and you want the most brute force performance you can get, an I7 Bloomfield is still the way to go it seems.

Of course if you are using multiple GPU's in your system them Bloomfield automatically has an advantage due to supporting duel 16x PCI-E slots.

For me at least, putting together an I7 920/X58 setup would have cost me £105 more than the I5 one I just built. Using the cheapest and as far as I know only X58 mATX board, the MSI one at £130 and then 6Gb of triple channel memory and an I7 920, add up the price differences on all that and the I5 750 setup using 4GB of dual channel memory and the £87 Gigabyte mATX board is substantially cheaper, and personally, I would not notice the difference given what I use my system for.

So draw your own conclusions from the evidence to date I say, but for me at least the Lynfields are great, I love the implementation of Turbo boost and the power efficiency is great. And they really are very fast, whichever way you look at it.

I would say only go for an I7 Bloomfield setup if you can realise the advantages that it does have, otherwise I think Lynfield would suite you better as an all-round platform.

I think i5 750 is very snappy and fast, only lags behind slightly when your overclock it to the max for benchmarking. For general usage, I highly doubt that you'd be able to tell the difference.

As a whole the i5 750 is good value for money for the lesser enthusiasts, but the 1366 x58 socket is the way to go if you want to have the option open for an i9 upgrade without having to buy a brand new motherboard.

Having said that, if I hadn't already got an i7 920, I would jump on to i5's anyday. Good value/performance and low power consumption!
 
One thing I've noticed about the Lynnfield's though they seem to need a lot more voltage than Bloomfield's to reach 4Ghz.
 
Think my mind is made up on a i15 will proberly just run it in turbo mode and not bother with the overclocking the only use will be gaming
