Super PI 1m takes 23 seconds? That's sh1te!

the C2d/i7 architechture can , in very basic terms, do 4 things per clock(excluding registers like sse4 which can greatly improve speed in things) in the best of circumstances, Superpi is one of them, I'm not sure I can name another. Superpi is essentially the most predictable, simple and easy thing a cpu can do, it fits perfectly on the Core architecture without question and it will not be beaten in it until another 4 issue core comes out, or a 5 from a next generation chip though may never come tbh. The phenom is a 3 issue core, not capable of 4, but efficient so it can fill up 3 "issues/instructions" per clock almost as often as the Core 2, which is why they are close on most things that aren't Superpi.

Imagine that 1% of instructions can use the 4 instructions, 35% can use 3 instructions, 64% can use 2 instructions.

Super pi fits every instruction within that 1% but no other programs do. Phenom is say 35% can use 3 instructions and 65% can use 2 instructions, but 99.9% of applications use 2/3 a clock as they are too complex/unpredictable to use them all.

A comparison would be ATi/Nvidia, nvidia have 240Stream processors, ATi has 800 but very very rarely manages to fill up all 800 instructions, at its worst it can only use, I forget the actual number but something along the lines of 160, but being that the clocks are quite a bit slower its the equivilent of being able to use say between 100 and 400 "nvidia" type stream processors, at its most efficient far more powerful, in reality due to software very similar in the end.

I think the 20th is unlikely, in so far as, we've see dates from the 16-18th, those two days in terms of pre-xmas shipping are a massive massive two days. 20-21st are the weekend pre x-mas meaning nothing would ship till the 22nd and no one would have them before xmas. the 16th-18th dates we've seen on several sites seem much more likely. The amount of free publicity AMD would get even releasing a tiny number pre-xmas would be huge.

Lots of people ordering them as their own xmas pressie, lots of people with time off work/uni, lots of people posting their clocking results on forums with more than usual numbers of people on them in the holidays.

How do these processors compare to 45nm core2 clock-for-clock? Is there any indication yet?
Click to expand...

early benches are showing the the Phenom 2's are just about beating the intel 45nm core 2 quads clock for clock... but its tight.

also about the pricing:

The first is listed as "AMD PHENOM II X4 920 2.8GHZ SKT AM2+ 8MB 125W PIB - HDX920XCGIBOX" at £191.44 inc. VAT (at 15 percent, not 17.5 percent), while the second is the "AMD PHENOM II X4 940 3.0GHZ BLACK SKT AM2+ 8MB 125W PIB - HDZ940XCGIBOX," which is a little more at £231.32 including VAT.

also did a google store search and come up with this:

AMD HDX920XCGIBOX AMD Phenom II X4 920 2.8 Ghz ... £193.49 - (but the item has been removed from their website)

while another store put the 920 @ £216.19 inc VAT

EDIT: also

Distributors in Europe and North America will begin shipping both OEM and retail boxes of the Phenom II 920 and Phenom II 940 starting December 18th (Europe), according to one distributor, and December 20th (North America).

only 3.64ghz? if thats max clock, not great because from benchmarks ive seen (if real) the phenom II is about 200mhz slower than a C2Q

i was really hoping AMD would come out almost as good as intels best this time, but it doesnt look like they are competing top end.

Price is justified by performance, though it does save you a good 200-300 compared to an i7.

read the thread Perfect... the title is Phenom II 920 does 3.64Ghz USING 1.4v

also "someone got hold of a retail 920 and has it [bold]so far[/bold] at 3.64 on air, [bold]without spending a great deal of time on it.[/bold]"

it doesn't say anywhere about that being the max clock as he would still be able to pump in some more volts...
 
Also remember that comparing to the older Penryns the Phenom II will most likely have the same kind of scaling as the Penom I did against the Conroe. After a set clock it will start performing better per clock because of the L3 cache latency lowering and some other smaller things.

This is something people forget. After about 3.2 - 3.4GHz or around that, the Phenom overtakes the Q6600 because it's L3 cache speeds up. The oringial Phenom only had 2MB cache, AFAIK this one has more of it.

Exactly, so say conservative estimates say itll be 10% faster than Phenom I, It means it'll be very much to Penryn what Phenom I was to Conroe. But now it has far more overclocking potential.

I wouldn't be surprised if 3.5Ghz+ these were faster than the penryns.
 
I'm not so sure, why are gaming benchmarks showing FPS around or slightly lower than a Quad conroe then if these are supposed to be quicker than conroes?

my point is if its almost identical performance whats the point in people buying this over a intel quad setup that is probably same price/cheaper :/
 
conroe's are duals not quad... and the denebs are matching the Yorkfield's clock for clock

all 2x/4xAA w/ single gtx280

STALKER CLEAR SKY, 1680x1050
Phenom II x4 940 3Ghz = 41.7
C2Q Q9550 2.83Ghz = 41.2

CRYSIS WARHEAD, 1680x1050
Phenom II x4 940 3Ghz = 35.7
C2Q Q9550 2.83Ghz = 35.0

DEAD SPACE, 1680x1050
Phenom II x4 940 3Ghz = 219.0
C2Q Q9550 2.83Ghz = 214.4

FAR CRY 2, 1680x1050
Phenom II x4 940 3Ghz = 54.4
C2Q Q9550 2.83Ghz = 46.2

WORLD AT WAR, 1680x1050
Phenom II x4 940 3Ghz = 48.7
C2Q Q9550 2.83Ghz = 57.3

WORLD IN CONFLICT, 1680x1050
Phenom II x4 940 3Ghz = 92.7
C2Q Q9550 2.83Ghz = 95.0

and yes the 940 is a higher clock but only just.
 
Does clock-for-clock speed really matter if you're going to be running it overclocked? Surely the important factor in that case is simply how fast they can run things when pushed to a sensible amount (ie, not stock, but not pushed so far they only last a month).
 
Nobody knows for certain, except people who can't say because of an NDA.

Here's all the rumoured dates.

January 8th
December 18th Europe, 20th US
December 24th Europe (delayed)

I think 3.5 on 1.2v would be pushing it a bit :p
Click to expand...

Hasn't someone on Xtreme managed 3.4GHz on 1.2v and 3.5 on stock?

Either way, the figures so far are pretty nice, I don't need anymore than 3.5Hz so if I can keep the volts and heat down I'd be in a good place...
 
I think that I'm going to go for AMD over Intel. If I buy an Athlon 64 X2 today, I could upgrade to one of these Phenom IIs once the price drops...

Hmmm....
