New Phenom II !!

[vasco fernandes]

O interessante não é o overclock espectacular de 6789ghz mas sim o rendimento do processador.
Que me adianta um processador que faça 6789ghz se tem um desempenho semelhante a um c2d a 2800mhz?

WTF ??!!

sou da mesma opinião...

q adianta eles fazerem 4500mhz a ar se uns Intel a 3500 o papa! (isto é só um exemplo!!)

[vasco fernandes]

só ainda n percebi onde ele foi buscar a ideia que um Phenom II a mais de 6GHz tinha a mesmo performance que um C2D a 2.8GHz.........

[Bad_Cop]

não foi. está a dar um exemplo.

se calhar ao invés de "tem" ficava melhor um "tiver", mas dá para perceber a ideia, não?

[vasco fernandes]

mas isso n vai acontecer, o Phenom 9950 a 2.6GHz estão quase ao nivel de um Q9450 que funka quase é mesmo frequencia, n vao agora os Phenom II ter uma relação frequencia/performance extremamente inferior ao actual Phenom

[Bad_Cop]

veremos. os phenom ao inicio também prometiam mundos e fundos e depois foi o que se viu. espero que venham bons, nos quad a intel ainda precisa de concorrência.

Se reparares eu ainda por cima aumentei a comparação em ghz e não mhz

Certíssimo Bad_cop...!!!

AMD Austin Tech Day - Information from the inside


Hey peeps!

I quite literally just got back to the hotel from AMD's Austin campus after a day with some rather interesting information being disclosed and freely discussed.

Unfortunately, the level of free discussion outside of the room is heavily covered by NDA so I'm unable to announce specific details. But this is what I can say...

The new platform from AMD will be called 'Dragon' and will be focused around the new 'Phenom II' processors, 4800-series Radeon graphics cards and 7-series chipset based motherboards.

Here are some general performance observations that I can disclose:

Phenom II and the Dragon platform can overclock to 4GHz on air - we were demonstrated a system @ 3.9GHz using stock bus frequency and HT link frequency and a multiplier set at 19.5x. This was done with 1.55v BIOS set. This system was looping endlessly through a Crysis time demo without issue; by the end of the day it was past 100 loops.

The platform core specifications demonstrated were as follows:

Phenom II processor
GIGABYTE GA-MA790GP-DS4H motherboard
Radeon HD4870X2 graphics
OCZ Reaper memory

While the unit demonstrated was @ 3.9GHz, we later had a hands on benching period with the new platform and I was able to quite easily reach this stated 4GHz frequency.

This same platform also exceeded 5GHz on liquid nitrogen cooling. But what was perhaps the coolest (no pun intended) specific of this demonstration was the processor operating and even cold booting at -196 degrees Celsius - that's right, AMD has no cold bugs of any kind, at all for Phenom II!

During this LN2 session the system was demonstrated operating in excess of 5GHz and running 1.95v BIOS set (1.936v CPU-Z read in Windows) and as stated, at the maximum lowest temps available with liquid nitrogen - time to find a liquid helium supplier peeps!

I'm gagged by the NDA on any further information and specifications such as model numbers, product features + specs, stock clock frequencies or even specific overclocked frequencies (i.e. LN2 max) as well as pricing, competitive performance or bench scores. So please, don't even bother asking me these questions as I cannot and will not answer these questions - at least until the NDA drops.

What I wanted to do with this post is at least let you all know that there is hope still for AMD and that while I've harped on about the LN2 experience, the overclocking ability is solid for LN2, phase, water and air cooling methods.

Cheers for the ego stroke but it's difficult to say exactly what the competition will be - also keep in mind I'm still under NDA.

But speaking purely from my knowledge of the Core and Nehalem micro-architectures compared with the design of the original Phenom and then cross referencing this with the design changes to be introduced in Phenom II (catch your breath - with me still?), then I think Phenom II will have to use scaleability to maintain any kind of competitive performance. I still believe that clock for clock it's design is not as efficient as Intel Nehalem micro-architecture; it's just too far ahead.

What we can hope for however is for Phenom II to be able to compete with the Penryn based Core processors (most noteably the Yorkfield based quads) and do so on a price point that is actually accessible to the large majority, not the lucky minority.

The biggest problem in terms of say 3DMark performance and thus general 3D performance was the lack of CPU cache - we'd see upwards of 3-5k drops in the CPU score in 3DMark06 when compared clock for clock vs Intel's 45nm Yorkfield quads. However now with a total of 8MB cache (6MB L3) we could see this rather drastically improved but this is in the most part assumptions based on what we do know. And what we do know is the performance of Intel's chips.

So in this respect, I guess I'm waiting as much as the next chap to find this information out. What we saw in Austin was basically stability testing at given frequencies using Crysis - we didn't see any comparative benchmarks such as 3DMark, Super Pi, wPrime etc. What I do believe though is that at the max clocks under LN2 we'll see AMD finally break the 10 second mark in Super Pi as a quick run I did @ 4GHz means it should scale to 10 second with another 2GHz frequency. Again, this is making assumptions on a linear scaling characteristic.

This means that with so many assumptions I'll either be on-point of I'll make an ass out of myself and anyone who chooses to mince my words

I got an email from AMD this morning stating that the embargo on the X2 7750 has been brought forward by several hours to Sunday, December 14th @ 7:01PM, EST.

When the NDA drops, I'll have some further info.

In the mean time, the email also included a notification that additional photographs had been added to AMD's Flickr account. Including this one:

AMD de regresso. Apesar de os CPU's estarem um bocado para o caro, o preço do resto da plataforma compensa. É, para já, uma escolha correcta na gama dos 250€. Um conjunto X4 920 + 790GX + 4GB DDR2 fica por menos de 450€.

Sim, mas ai perde muito da vantagem dos Phenom II. O DDR3 está demasiado caro, por enquanto, e o aumento de desempenho é esperado ser apenas por volta dos 5%
