Core i7 980X doesn't seem much faster than Core i7 860?

[andy5174]

People worry about high current more than high voltage, because high current cause a lot of energy lost and heat. That's why power companies use high voltage and low current setting to deliver power to individual houses.

If the current and voltage of two CPUs are all within spec, I will choose the one with lower current.

 

[andy5174]

The architecture revolution(90nm -> 65nm -> 45nm -> 32nm) is done to raise efficiency, reduce the leakage current and heat.

You will be definitely within the absolute max just like 920 at 4GHz+. The article do mention higher Vcore on LGA1156, but you will be fine as long as you are within spec. In addition, the absolute max Vcore on LGA1156 is higher! Besides, I have seen a few 750 at 4.2GHz.

Again:


BTW, there are not much 920 can do 4.2GHz as well. You can see a lot of 920 D0 owners also have trouble at about 3.8GHz ~ 4GHz if you do some search. Google!

Yes, I know D0s aren't guaranteed to do anything in particular, but they seem to go higher than 750s on average.

Even a C0 will often do 4.0 without too much hassle but a lot of ppl like HT too much and therefore stay below 4GHz.

I'm doing 3.8 with HT on and loving it.

I wouldn't want to trade my 920 for anything really. Not for 700 because of the lack of HT and not for the 800 because of the high vcore requirements and the limit on PCIe lanes. They have to be cheaper to convince me.

Great! I can get better i7/i9 with new X68 MB later when their prices drop.

X68 is still a year away. It's great that you love your 750 but don't try and compare it favorably with the the 920. It just makes you look like a jealous troll trying to make himself feel better for choosing the inferior socket.

Not very cool Joseph. Don't make these type of posts a habit, and we'll get along just fine.

It's more like you are upset about the x68 release. Don't be silly!

didnt i say this a while ago..

but it wont be soon.

Not anywhere CLOSE yet.

I heard expect it when you start hearing about 10GB lan.

I know and that is why I said it would be my next upgrade later on.

 

[aigomorla]

I dont think intel is gonna dick us around on platforms, like gpu vendors are doing.

So there going to wait til its fully mature to go on.

The X68 is going to be nice, how nice... i have no absolutely clue, but USB3.0, DMI 2.0, and 10GB Lan, are among the first things i saw on the sheet.

Read the article from the link below. It is about the new BJT & PCU(power control unit) on LGA1156 platform which acts as a TRUE switch. This means that there's almost no leakage current at idle state.

Andy, ALL Nehalem architecture CPUs have the same PCU and the power gating transistor. It's just that on Lynnfield(Socket 1156) it can also use power gating for the Uncore, while Bloomfield(Socket 1366) can only do that for the cores.

Why would he be upset?

The gulftown processor will be a dropin replacement for a 920. And the X68 chipset isn't suppose to be out for another year.

where as anyone on 1156 can't even look at gulftown.

Not true. The transistor of LGA1156 has been improved.

BTW, LGA1156 would run hotter if transistor was not improved due it having more transistors thanks to on die PCIE controller.

Read the article from the link provided by me.

I always upgrade the MB with CPU even I am not forced to do so. Thus, I don't consider the upgradibility of MB and that's why I get LGA1156 which has a compatible i7-860 that performs better than 920 most of the time and being cheaper overall.

Furthermore, I believe 99.99% of LGA1366 owners can't afford Gulftown in the near future. Hence, the future proof you mentioned is a joke.

You two are just upset to see your expensive X58 will be extremely outdated by the time 32nm 6-core drop to affordable price and so start being rude when others say that they will upgrade to the new x68 later.

All I said was that it would be great to upgrade to x68 + AFFORDABLE Gulftown later. What are you two mad about?!

 

[tweakboy]

You will not notice a difference in speed. Its already soo fast. trust me.
Dont expect to see a difference, unless your rendering,, or running a DAW

And that my friend is exactly what we do! Hurry up and release the damn Xeon version of this INTEL!

That's gonna be expensive with mid range memory configs (64GB). We just placed an order for Dell Precision 750s and talk about sticker shock!

A 860 is only faster stock, and I don't know about you but my rig is not stock. I am one of those people that could afford to buy a Gulftown processor if I so choose to. Not everyone upgrades like you do, I will buy an expensive motherboard and try to drop as many processor upgrades into it as I can. Chipset revisions usually don't bring huge performance gains, the same reason I could careless for USB 3.0 or SATA 6 Gbps as all my external Drives are ESATA.

Where does it show in my post that I was upset?? You sure make alot of assumptions!

lol I was rude? I could careless if you bought a Pentium 2 or a X68 that is your money and your business.

All I did was state a fact in my post that is it!

Most of us CAN afford Gulftown in the near future, but 99.99% of us are just not willing to and DEFINITELY not going to pay for it.

The X58 will be extremely outdated by the time we are WILLING to pay for the Gulftown which is a truth as well.

BTW, I can also afford a X58+i7-975 as well when I was building my rig a while ago, but the performance gain is not worth the premium and so I skip it.

 

[DrMrLordX]

Another potential reason to skip LGA1156: http://forums.anandtech.com/showthread.php?t=332659

 

[andy5174]

Reasons to skip LGA1366 when there is LGA1156:

- High cost(~52.7% more than LGA1156 i5 according to newegg pricing)
- insignificant performance gain with more expensive tri channel currently
- insignificant PCIE performance gain with 2x CF/SLI
- 3/4 high end GPU supports which 99.99% LGA1366 owners can't afford.
- $999 Gulftown upgradability in the near future which 99.99% LGA1366 owners can't afford.
- extremely outdated by the time Gulftown becomes affordable and x68 will be released.
- worse transistor
- a lot of unnecessary leakage current
- runs very hot
- immensely inefficient compared to LGA1156

Go for LGA1366 if you are willing to pay 52.7% more for 3~4% performance gain compared to i5.

p.s. Even 10% less fps under high resolution means merely 4~5fps less which is unnoticeable.

 

[andy5174]

The best product is always the worst in cost-performance ratio and normally it is only slightly better than the 2nd/3rd.

 

[Makaveli]

Your post are jokes!

You make these statements like you know what other people can and cannot afford like its fact.

when I priced out my system build the cost difference was just over $100. I don't know what planet you live on but that wasn't a 52% increase in price.

i'm not even gonna respond to these post anymore starting to become to troll like.

Next thing you are gonna say is because Phenom II can equal an i7 or better it at higher resolutions on certain games its a better buy.

This post shouldn't be here if you don't respond.

All you can do is acting unreasonably when you can't go against others' arguments, kid.

BTW, we are both off topic!
