Anandtech: AMD's 65nm Preview Part 2 - The Plot Thickens (Updated) - Page 2

post #11 of 25
This is depressing.......4x4 is a joke, I would have thought 65nm tech would have overshadowed that power sucking embarrassment.

well, they doubled the amount of cashe, and their using a 65nm process that they have little knowledge about 65nm chips. patience will be nessesary for real performance to arise from amd, as they still need to refine the technology. also, keep in mind these chips are prototypes.

I think they actually halved the amount of cache, most certainly they didn't double it. Have you seen any CPU with 2Mb L2 cache per core?

These chips are not prototypes or ES, they are final products that are shipping as we speak.

The reason I still bought a Pentium 4 570J instead of a C2D. It was 2/3rd's the price which doesn't compensate much, but it's still fun to play with and still packs a punch. I'm personally waiting for 45nm.

Voltages that rise, latencies that rise, and a die that shrinks? There is one serious kink in the manufacturing going on here.

I bought mine because of the huge overclocking potential. I got mine for $215 and brought it up to 4GHz very easily (after getting a new mobo, 1st one was a dud). Its faster than a stock FX-55 in most things, which cost $855 at the time.

At least Intel had overclockability going for them in the Netburst days. Now AMD doesnt even have that going for them. They need to do something or theyll start to lose market share pretty quick.

And I dont know why AMD thinks SOI (Silicon-On-Insulator) is so great. If they went with strained silicon, they could still save power and greatly increase the maximum clockspeeds their CPUs support.

From Wikipedia:
Quote:
Strained silicon is a layer of silicon in which the silicon atoms are stretched beyond their normal interatomic distance. This is accomplished by putting the layer of silicon over a substrate of silicon germanium (SiGe). As the atoms in the silicon layer align with the atoms in the silicon germanium layer where the atoms are farther apart, the silicon atoms become stretched - thereby leading to strained silicon. Moving these silicon atoms farther apart reduces the atomic forces that interfere with the movement of electrons through the transistors, subsequently resulting in better chip performance and lower energy consumption. The electrons in strained silicon can move 70% faster allowing strained silicon transistors to operate 35% faster in performance. Strained silicon strategy involves either inserting germanium atoms into silicon lattice or adding intermediate layer of silicon-germanium compound semiconductor. More recent advances include deposition of strained silicon using metalorganic vapor phase epitaxy (MOVPE) with metalorganics as starting sources, e.g. silicon sources (silane and dichlorosilane) and germanium sources (germane, germanium tetrachloride, and isobutylgermane).

AMD has been just gaining market share, so they obviously arnt loosing any.

And AMD does use Strained Silicon.

Wow, would AMD actually release their products instead of hyping about them for 6 months, it's getting rather old.

Intel did too, initially, until people started seeing how much better K8 was than Netburst.

And I thought AMD had stopped using SS in an effort to increase production in order to help alleviate the shortages it was faced with.
