Core Voltage - Lowered to 1.2 Volts

Ad

Our 65 nm sample of the Phenom processor operated at a core voltage of 1.225 Volts. When the processor switches to power saving mode, the voltage is reduced to 1.050 Volts. The BIOS still offers core voltage options to facilitate overclocking.

 
Temperatures
 
 We used the Zalman CNPS9700 LED to cool the Phenom 9700 CPU, stressing it by running the multi-threaded version of Prime95 for half an hour. With the fan running at full speed, the CPU temperature reached 38°C. Reducing the fan speed resulted in a temperature of 45°C. When idle, the CPU stayed rather cool at only 32°C.

"Intel, since the chip giant has already announced that its current high-end platform X38 will be incompatible to the next generation of high-end CPUs at the beginning of next year."

I'd rather have a slower processor but not have to rebuy the 3 of the most expensive components (CPU, mobo, and RAM) every time I want to upgrade something. That's why I've stuck with AMD for the last few years. Can't wait to drop a couple of Phenom FXs in to my 4x4 platform and have 8 processing cores.

Not so sure about forthcoming compatibility.

What is going to happen when AMD shortly moves to 45nm processors with DDR3 memory controllers?

unless AMD are going to put both DDR2 and DDR3 memory controllers on their 45nm processors or make them in both DDR2 and DDR3 versions then you will have to change you're ram, motherboard and processor to go 45nm.(that didn't happen with intel)

Unless motherboard makers put both DDR2 and DDR3 slots on current boards although the latter wouldn't be supported until 45nm come in.(can't see that happening though).

why do the companies have to be so selfish with this incompatable SSE thingy....

P21, that table isn't really taking the quad core part into account... because look, in things like supreme commander its quite a bit faster... (which is important to me...)

LOL at the .1% extra value for money compared to the q6600, AMD clearly did that to annoy intel...

Well seen as though thats a brand new chipset as well wouldn't it be a little foolish to expect full performance straight out of the box ?

I think these chips have more to come, thats an engineering sample and the mainboards got a chipset with undeveloped drivers.

I say give it a month for the nvidia chipset....... and retest.

Intels @4Ghz OC on air... AMD is on @3Ghz OC on air... Oh dear...

I can see why they need 4x Crossfire boards given the lack luster performance of the new ATI cards... ATI seem to be struggling since their Cope-de-grace with the X19xx series...

AMD clearly has a good design (architecture) but the process technology is their achilles heal. They need 4Mb+ L3 cache, high K transistor process, and 45nm like yesterday!!

As a bit of an AMD fanboy (I'm on a dual Opteron rig just now) I hate to see whats happening to them now!!

Bob if AMD was having 4mb+ L3 cache, high K transistor process and 45nm it will be twice expensive as the intel's solutions.

P.S. But it will be better :P.. I'm currently on a AMD Athlon 64 X2 5000+.. and it's a bit overclocked(from 2.6 GHz to 3.01 Ghz) ..I'm on water although. Wish AMD be back on top!

I think for server setups this HT 3.0 is gonna shine. More so if you want to build a super-computer system. The bandwidth gains are enormous. But the actual core performance..sorry AMD, but this is just a little disappointing. Intel's current stock is already ahead of you. Perhaps 45nm products will address this (and allow for more L3 cache).

Overall, I like the way AMD has gone for compatibility and performance. The price is phenomenal and the ease of implementation will ensure downtime during upgrades is kept to a minimum. It's easy to under-estimate just how hard that is to pull off.

One of the CPU-Z pics shows a higher Vcore? Come on lads..who'se been naughty! ;) p.s. I would.
