ASUS P6T family - all about it.

[mariniam]

About 15.500s. i7 is way faster even with 300MHz lower clocks

But how is it way faster? They both do virtually the same time in super pi with stock settings. The 300 MHz diff isn't a lot considering this is a new super duper CPU.

[jaredpace]

so the 4ghz i7 did a 16mb PI in 4min 46sec.

how long does it take for a 4ghz e8400 or a 4ghz quad?

hes just saying that its more powerful clock for clock, and you cant measure cpu performance with spi. especially when your doing a oranges to apples comparison, their completely different cpus

unoptimised runs on P5Q Dlx (not a good chipset for superpi) C5-5-5-15 PL 9 :

4Ghz Qx9650/P45 mobo 10 x 400FSB / ram at 1066 : 16Mb PI : 5 min 32 sec
4Ghz Qx9650/P45 mobo 10 x 400FSB / ram at 1200 : 16Mb PI : 5 min 22 sec
4Ghz QX9650/P45 mobo 9 x 450FSB / ram at 1200 : 16Mb PI : 5 min 17 sec

Think a good optimised X48 can come very close to it's scores. But Nehalem will smoke any current existing CPU in it's path in an optimised software environment... looking forward to more results Pmp, looks good

[Chri$ch]

Bloomfield @ 4GHz / ram at DDR3-1600 : 32M Pi : ~10min 2sek

[dionysio]

at this point i will stand very critical against asus. after the commando/maximus formula/rampage formula fiascos i _suggest_ serious overclockers to examine very carefully asus's latest offerings...
even as it seems rampage extreme has almost all flaws corrected still i will not easily forget my pasts experineces with the previous rog mobos... i am waiting for your comments people...

[PytonOrm]

But little to much vcore for 4ghz with nehalem ? look at the cpu-z pic and over 1,45v :S not so good well ? soon you gonna fry your cpu

[CryptiK]

Thanks for the preview.

That's a lot of voltage for that cpu speed. By comparison, a nice Qx9650 can do 4.5GHz on that voltage, and would be faster than the 4GHz i7 at that speed. The only thing that would make DDR3-1066 CL6 ram have good bandwidth is triple channel, dual channel it is worse than current DDR2.

Can we see some 3D benches please and Triple channel ram benches? I'd like to see what it can do with more bandwidth. Also it would be good to see what the cpu/system can do using a reasonable voltage orthos stable overclock, similar to what people would be comfortable running themselves, say at 1.36v or less.

EDIT - For comparison to i& & Leeghoofd's SPI1M runs:

E8400 @ 4Ghz, P45 mobo 9 x 445FSB / ram at 1113 : 16Mb PI : 5 min 32 sec (with internet browser open in background).

No, we don't know yet. I don't think we got to know whether Nehalem tolerates more, less or the same amount of voltage, but maybe I simply missed it.
-- So do the Nehalems tolerate the high voltage, pmp?

By comparison, a nice Qx9650 can do 4.5GHz on that voltage, and would be faster than the 4GHz i7 at that speed.

No, it would be about similar or slower in multi-threaded benches and bandwidth heavy tests. Perhaps better in single threaded applications.

well do you want your new cpu for synthetic tests & bandwidth benchmarks, or for applications?

[Oliver]

sweet Jakub thx for posting

[Jacky]

Well there is enough real-world multi-threaded software out there and still quite some single-threaded stuff too. Nehalem may be ~10% faster in single threaded apps, and destroy anything else in multi-threaded, thus a 4ghz Nehalem might be superior. So no need for rolling eyes.

[sdumper]

How do these chips handle the cold...say if we chill it down to -140c and pump 1.8vcore through it. Will it be able to hit 6ghz or simply fry...

[mikeyakame]

You guys need to remember that a lot of these tests done for i7 are on early C0 stepping ES chips. Retail will be C1 stepping from what Intel have said so far and will have some improvements and changes from the C0.

[pmp]

My source, i believe very reliable, told me that C0 actual would be the retail stepping. Tho before official NDA liftup, i decided not to answer questions regarding - if the chip takes well high voltages, etc.
Just to not let bad information spread. What can i say now, it's promising, but still very fragile/sensitive.

sdumper - C0 takes the cold temps, according to my source (haven't test it yet myself under LN2), as good as we can expect. For _sure_ new 3D06 WR are coming/done already :P

[mikeyakame]

Sounds promising. NDA will be lifted soon enough then we will all find out after all nothing worse than bad rumours being spread from misconceptions.

[WaterFlex]

Thanks for this info! Nice CPU and Nice Tripple DDR3 !

[pmp]

Can we see some 3D benches please and Triple channel ram benches? I'd like to see what it can do with more bandwidth.

In progress:

SuperPI 1.5 XS without single tweak / Dual Channel

SuperPI 1.5 XS without single tweak / Triple Channel

Everest Triple vs Dual Channel Memory Benchmark
Please noticed B0 chip is used and it may affect the performance It should be ass kicking, and it's not.

[Chri$ch]

Ok, everest looks bad... (dc better latency as tc?)

[slim142]

$500 - Naaaah
Im sorry for the dissapointment that many are going to have...

[WaterFlex]

Ohhhh! Awful everest results!
No thanks.

[OBR]

pmp can you post newest BIOS ...

[jeevster]

Does someone know what's the difference between the p6t deluxe and WS edition? For example in terms of overclocking etc.

tnx

[stasio]

P6T Deluxe 0804 Bios
1. Improve Memory compatibility
2. Revised QPI/DRAM Core Voltage setting in CPU Level Up
3. Support new CPUs.

P6T-WS-PRO 0302 Bios
1.Supported 1333MHz of X.M.P.

Rampage II Extreme 0503 Bios
1.Revised QPI/DRAM Core Voltage setting in CPU Level Up

[Kazi]

Pmp,

Why did you run the i7 920 at stock FSB?
Is it the ram that is holding you back?
Are you using a tripple channel kit rated for 1.65v or a upgraded dualchannel kit?
Could you post some picks of memory bandwith and latency with memspeed around 800 Mhz?
