Core i7-4770K: Haswell's Performance, Previewed

[kevin83]

I'm really liking the numbers here. By my calculations we're looking at this chip being something like 35% faster than my current 2500k at the same clock speeds, with the obvious potential that the new chips overclock better. Lets hope they fixed whatever made temperatures so bad in Ivy Bridge!
Also, I'm pegging the chip at 8% faster than Ivy bridge's 3770k and 18% faster than the 2700k, I trust the numbers that come out of handbrake.
What will be really interesting is to see the performance gains in programs that are compiled to take advantage of AVX2 instructions.

Umm, because a 2500K has 4 cores, and the 4770K has 4 +4 cores. Handbrake is famous for using Hyperthreading advantagously.
Basically, a 4770K is as much better than a 3770K, as a 3770K is over a 2700K . Which means, a 4770K is about 10% faster than a Sandy bridge.
Revolutionary, eh ?

It has been shown in memory reviews that memory bandwidth has an impact on intel's IGP perfomance. If bandwidth numbers are to be improved on production hardware, the IGP will see some improved frame rates as well. As the reviewer pointed out though, it won't change a gamer from purchasing dedicated graphics.

^ gamer and intel iGPU still dont match :lol:

 

[monsta]

hmm not worth the upgrade from IB, gonna sit this one out

We know from our talks with motherboard vendors at this year’s CES that you’ll be able to buy Haswell in LGA 1150 trim, but that its successor, Broadwell, is going to be BGA-only (meaning it’ll ship soldered onto motherboards). Now, it’s possible that Skylake, the architecture to follow Broadwell, will see Intel re-introduce an upgradeable interface.

Is this means that Broadwell chips will be sold by a third-party? I am courious about Skylake too. Anyone know more about this?

 

[mayankleoboy1]

^ No and No.

It is interesting that this is the second generation of Intel chips to come out after the 2600K and it still is marginal in many areas as far as improvement. My 2600K based computer is very fast and I have not even overclocked it because I simply don't need the extra speed - I am not a heavy gamer.

I wonder if the 4770 will be a big step up for gamers. Aside from their world, I am not sure how many users will need to switch unless you are running heavy science or CAD applications.

Intel will have to put something out with real, tangible benefits of some kind before I will upgrade again. Adding a better UI, better SSD speed, better, quicker graphics - this would be something that I would be interested in. May the 4770 has some of these features because I have not really researched it (Vt-d for example) but so far I am not impressed.

[citation]why did haswell lose 5 pins? [/citation]
I doubt there is any good reason. But i dont beleive its a beneficial move. Many people who might want to upgrade from a 1155 socket cpu arent going to want to buy a new motherboard, they will find an IB or SB i5/i7, possibly second hand on ebay. Thats a sale for your new cpu lost right there Intel.

 

[cats_Paw]

hmm, i7... 4 cores, not 6....
Not sure worth it. Even my Q6600 has 4 cores (well, its crap compared to that CPU, but with console ports, dont really need a better one).

Apart from Starcraft 2 (and i dont even like the game, *sniff*) it gets playable framerates in all games, so...

 

[Cons29]

ill pass (using 2500k) this one it seems (well, not that i have the money to burn lol)
yes i know this is a preview.

but even if this one blows SB out of the water, the thing is if you have an unlocked cpu, you can and probably is already overclocked it. So for games and such, it will give us additional time to hold off.

 

[Cons29]

and since this is a new socket, nother big reason for me to sit this one out. i dont like to buy another set of board and cpu. even if i can sell my current set

 

[ianj14]

...I’m looking forward to getting my hands on Ivy Bridge-E...

Are we even going to get an Ivy Bridge-E? It seems it's now delayed to QTR 4, and there are rumours that seem to have some logic to them that Intel might skip IB-E and go straight to Haswell-E.

 

[TheBigTroll]

it wont run as hot as ivy birdge. intel engineer did a ama on reddit and called it a overclocking dream

 

[butremor]

Wonder how much will vendors charge for those new CPUs in countries other than US?

 

[demonhorde665]

The nubmers arnt that stunning really , I'm more stunned by the fact that intel still has yet to release an 8 core cpu for general consumers. normally an AMD fan because of pricing , but i'd love to see what an intel 8 core could do. i8 any one ?

 

[sanilmahambre]

Low to moderate gains. GPU was beefed up a bit. Hope these things OC well cause so far its not looking like a great step up from Ivy.

Will be nice to see what Final silicon and proper release benchmarks plus OC'ing show

I do agree that the size of this step may be determined only after release of it OC benchmarks

 

[mayankleoboy1]

I dont think this is going to OC any better than IB generation.
If it did OC better, Intel would wither increase the top bins for 1/2/3/4 cores active , or ship with higher base clocks.

Performance was to be expected, but I'm disapointed by the lack of innovation on the 8 chipset. I'm on C2D now. Was planning to upgrade to SB, but waited for IB. IB comes with PCIE3 and USB3, which is nice, and can still overclock easily to 4.5 (which is more than enough for me). But now, seeing Haswell's preleminary results, I don't see why I would choose the latter over IB. I guess the price will make the final decision easier, but if it's anything like SB/IB, they will bump IB a little so it's more expensive to help sell the new architecture.

Oh well, let's wait and see.

[citation][nom]cangelini[/nom]Thanks--and yeah, VT-d is being excluded from these K-series parts, too. Funny thing is that it'll be enabled on the -4770, but not the -4770K.[/citation]
Isn't that the case with current models too? Though i guess it sort of makes sense, people who run virtual environments would favor stability over unlocked multipliers. :|

(or at least that's what i think Intel thinks)

Side note: Will be some time before i'll be able to read this (an hour or two, maybe), but Chris, you lucky, lucky man. All the goodies at your doorstep months before we, mere mortals, ever get to even touch one of these things.

Around $360 for a 3770 in India by the current exchange rate.

The benefit is that people don't put a CPU into an incompatible socket. Haswell was never going to be backwards compatible. So, by changing the package it prevents erroneous installations.

Looks promising, but about the issue of soldering. On Ivy they said because of the 22nm production the solder was prone to cracking, I don't see how going even smaller will help so we will likely see the TIM and glue. It wasn't necessarily the TIM that was bad, it was the amount of glue they used causing the IHS to not make direct contact with the die. If you've ever taken an Ivy chip apart you would know what I'm talking about.

Personally I rather have it glued because I am very comfortable taking the lid off, replacing the TIM with Coolabs Liquid Ultra, scraping all the glue off, and enjoying temperatures even lower than a soldered solution could produce.

But I can understand why the majority of people would not want to take a razorblade to a $350 CPU.

 

[dgingeri]

They're not changing anything on the CPU side, again. This is bogus. We're going to live through another year of absolutely no progress in CPU architecture? If Intel doesn't bring us something new and more advanced with IB-E, or at the very least cheaper 6-core CPUs, I'll be really ticked.

 

[tipoo]

I wonder what the performance lead will be for the graphics chips with embedded eDRAM?
