Default The Lynnfield Preview: Rumblings of Revenge [Anand]

Quote:
Lynnfield marks Intel’s third generation Nehalem turbo and is correspondingly more awesome.

The leaked roadmaps show that the two higher end Lynnfields can turbo up to five bins, or 667MHz while the entry level Lynnfield can turbo up to four bins (533MHz). I’m guessing this is for a single active core, but what about when more than one core is active? The table below has the turbo specs for the Xeon X5570 (95W TDP), the Core i7-940 (130W TDP) and my guesstimates for the 2.93GHz Lynnfield (95W TDP):

It does, although we're still left wondering exactly how Intel is going to position this alongside i7. Still, the results aren't too surprising - all it's really missing is a third memory channel (which is really only beneficial for synthetics/server), and the high-bandwidth IOH connection for the PCI-E (which we're in no danger of saturating anyway). I wish they'd been a little more thorough in their power consumption investigations. Even if an apples-to-apples was impossible, showing a 2.13GHz chip drawing less power than a 2.66GHz (old uArch) is only a little bit informative.

The i7 chips are great... for 3d/2d rendering they are just amazing.
My little 920 beat dual Xeons in a Yafaray rendering benchmark using Vista64... and I don't even know what I'm doing really.
The only higher scores were using Linux, which I haven't tried yet.
I'm sure I could get the top spot if I try out Linux (unless one of you i7 owners want to get over there and give it a shot).

i5 looks like it's going to be great too.
It'll be really interesting to see where this all goes from here...

i think that the i5 will be the next Core 2 Duo in terms of popularity.

i7 is worth it big time, sorry I have a feeling DX11 will need alot of memory bandwidth and hey even the i7 QPI will come into play.

SLI/X-fire on a non nvidia chipset + wicked over clocking, potential for 6 and 8 core cpu's.
I7 isnt expensive, just the motherboard..but hey you can buy one used and save a few hundred.

300 for the cpu
200-300 for a decent motherboard
100-130 for 6gb ddr3 1600.

Its a fair price for the value with sli.


ATI makes a better card? Sell my nvidia and buy two of the new ATI. Great Flexibility as well as tri-channel helps HUGE in games. Benchmarks or not I have less texture pop in with crysis when a new highly detailed scene pops up. Its drastic and just feels smoother overall. It isnt a big FPS boost, but just the way the system delivers data makes it feel beefy with stressful games/apps.

i7 is worth picking up, I'd recommend it any day.

For those who already own a Q9400 or Q9550, don't change for the i5 750 before you read this: Intel Lynnfield : Core i5 750, Core i7 870 et 860 or if you don't read french: "...In the meantime, we wonder which fly has dive Intel by proposing a price twice as important for Core i7 870 with regard to 860 while there is only 133 MHz who separate them. It makes the 870 a processor overvalued and theoretically completely useless price. Core i5 750 from his part is announced in 199 dollars, what places it between Core 2 Quad Q9400 ( 183 dollars) and Core 2 Quad 9550 ( 266 dollars). In terms of performances, it is closer to Q9550 than to Q9400. it is really of the level of Q9450 which is regrettably no more present in the official list of the prices of the giant of Santa Clara.".

Totally irrelevant review since not only did they have Turbo Boost disabled, but they crippled the Lynnfield chips with DDR3-1066.

And if you overclock a Q9550, will you have the same effect as turbo boost? As I understand it, unabling turbo boost overclock the i5 chip when needed... Is that right?

Turbo boost is a fancy word for auto-overclocking depending on the demand on cores. But then again it also shuts off un-needed cores I think....
