Actually half-yearly taking place Intel Developer forum (IDF) is to place the newest research results from the house Intel into the foreground. Ore rival AMD uses the meeting however already almost traditionally, in order to sit down and from the competitor the show steal in scene. So also this year, in which AMD offered the announcement of its first Dual-Core-Turion-64-CPU and besides three new Opteron CCUs as well as promised a base change. Besides of Intel almost went down new processor architecture “core”.
Trend: Single core was yesterday - now dual core CCUs govern
Turion 64 X2 - AMDs first two-core processor for Notebooks will presumably come in the second quarter of this yearly on the market, with details however still holds back themselves AMD. Only the new Logo was already revealed. In puncto clock frequency, Cachegrösse, front Side bus and feature so far however still no details oozed; it stands firmly only that the CCU with standard DDR2-Unterstützung will be delivered.
This will be also a component of the dual core Opteron processor announced for the third quarter (“Santa pink one”) for the base F, which is to be equipped beyond that also with the Virtualisierungstechnologie Pacifica. The CCU with a capacity of only 95 Watts will mark the beginning of a new chip generation in the house Intel: Full 1,207 signal contacts (keyword “country Grid array”, LGA) will replace the CCU pins used so far and will thus ring in a new base era, which will be relevant among other things also for for 2007 planned Quad core variants of the Opteron.
Still into the old base the again presented dual core Opteron models 885, 285 and 185 fit for servers and workstations. The CCUs have all together two processor cores and clocks with 2.6 gigahertz, with which they place themselves against the point of the Opteron series. The Opteron 885 for eight-way servers as well as the 285 for systems with two processor versions and costs with acceptance in units of piece of rope the 2,149 each US Dollar is already available respectively 1,051 US Dollar. Still no price is certain for the third CCU in the federation, the Opteron 185. The processor for one-way servers will however also only be available within the next 30 days. Among the manufacturers, that want to offer systems on basis of the new Opteron CCUs, rank among other things IBM, Sun Microsystems and HEWLETT PACKARD.
Intel: New CCU architecture is to point AMD again into the barriers
As much act urge in the house AMD must have ore competitor Intel set naturally somewhat against, if the past Branchenprimus does not want to drop back behind “eternal second”. Justin Rattner, of Intel senior Fellow and Chief Technology Officer, is in this connection however optimistic: How it admits now in the context Intel of the Developer of forum in San Francisco gave, Intel wants to defend its market position with the help of new CCUs on basis of a faster and river more saving chip architecture. This was already announced for the first time in the context of the last IDF in August 2005.
New micro architecture, official successor of “Netburst”, hears this yearly with the two-core processor beginners “Conroe” (Desktop), “Merom” (Notebook) and “Woodcrest” (server) on the name “core” and is in the second half on the market to already come. The chips are manufactured at first in 65-Nanometer-Struktur; 2007 are to be changed over however to a production process into 45 nanometers. Then are also the first “core” - Quad CCUs (“Clovertown”, “tiger clay/tone”) to be presented.
More efficiently and river more saving - in short: more efficiently
Design-technically it concerns on the whole with “core” an advancement of the current Pentium M architecture (“Yonah”), whose CCU descendants are characteristically likewise duo, are called as “core”, i.e. Intel core. Were added ncoh some already well-known features of the Pentium-4-Prozessortechnologie as well as some new functions, which still more efficient the function of the chips was to make. In addition among other things 14 stages count a long pipeline with quadruple multi-scalar Design, which makes it possible, several tasks (simultaneous) within a clock cycle to process as well as a thought out current management, with which individual ranges of the processor can be switched off purposefully, if these are not used. Besides now all SSE instructions (SSE1, -2, -3 and -4) are also implemented, with 128-Bit-Datenbus, in only one clock cycle instead of so far two.
Altogether the new “core” - CCUs should be clearly higher performance, but at the same time also substantially energy more saving than their predecessors: According to data of Intel a “Woodcrest” places - processor with 3,0 GHz a dual core Xeon with 2,8 GHz even with a performance balance in the shade, with one around 35 per cent of reduced capacity, increased by 80 per cent. Spektulär, but still considerably the comparison between “Conroe” is somewhat less and of Intel point CCU Pentium D 950, where the values within both ranges - achievement and energy - around 40 per cent in favor of the coming chip from “core” - fail basis. The Notebook processor “Merom” is besides to 20 per cent more performance to offer than the current “Yonah” - CCU, with power consumption however remained the same.
