MEDION Notebook med ATI,Vista,DVB-T & DVI

Der er (mindst) 2 ting i denne påstand, som er værd at kommentere: 1) Han 'tvivler' og ved det altså ikke og 2) selv om den ikke kan vise det over DVI udgangen - hvilket ville være mærkeligt og ulogisk, så kan den stadig vise det på den indbyggede 17 tommer 16:10 skærm.

Mine alarmklokker ringer når producenten ingen steder nævner ordet HDCP i forbindelse med et produkts digitale forbindelser, når man ved hvor vigtigt det er for at kunden bliver 100% tilfreds med sit produkt, så skal man også levere et produkt som lever op til salgstalen i en annonce.

Jeg har ingen interesse i at være ude efter Medion PC'en, jeg synes bare det er ærgeligt, hvis et umiddelbart godt produkt, ikke lever op til de fine specs som der nævnes.

Køb endelig denne Medion PC, men vær opmærksom på kravene fra Microsoft til Vista, og det er minimums krav vi taler om. http://www.microsoft.com/danmark/windowsvista/getready/syste mrequirements.mspx

Læg mærke til det er minimumskrav for at kunne køre kernefunktioner i Vista, ikke styresystemet fuldt, her kræves der min. 1 GZ processor, og 1 GB RAM til forskel fra det nævnte i linket. Herunder kommer så RAM til de forskellige programmer du skal køre ved siden af.

Core Duo is the world's first low-power (less than 25 watts) Dual Core microprocessor, with the previous low being AMD's Opteron 260 and 860 HE at 55 watts. Core Duo was released on 5 January 2006, with the other components of the Napa platform. It is the first Intel processor to be used in Apple Macintosh products (although the Apple Developer Transition Kit machines, non-production units distributed to some developers, used Pentium 4 processors).[1]

Technical specifications

Core Duo contains 151 million transistors, including the shared 2 MiB L2 cache. Yonah's execution core contains a 12 stage pipeline, forecast to eventually be able to run at a maximum frequency of 2.33–2.50 GHz. The communication between the L2 cache and both execution cores is handled by an arbitration bus unit, which reduces cache coherency traffic over the FSB, at the expense of raising the core-to-L2 latency from 10 clock cycles (in the Dothan Pentium M) to 14 clock cycles. The increase in clock frequency offsets the impact of the increased clock cycle latency. The power management components of the core features improved grained thermal control, as well as independent scaling of power between the two cores, resulting in very efficient management of power.

Core processors communicate with the system chipset over a 667 MT/s front side bus (FSB), up from 533 MT/s used by the fastest Pentium M.

Yonah is supported by the 945GM, 945PM, 945GT, 965GM, 965PM, and 965GT system chipsets. Core Duo and Core Solo use Socket M. Due to pin arrangement and new chipset functions are not compatible with any previous Pentium M motherboard.

The T2300E was later introduced as a replacement for the T2300. It has dropped support for Virtualization Technology. Early Intel specifications mistakenly claimed a halving of the Thermal Design Power.

New T2050 & T2250 have also appeared in OEM systems as a low-cost option with a lower 533Mhz FSB and no Virtualization Technology. No official data on these processors is yet available from Intel.<

Advantages and shortcomings

In many categories of performance (which support both cores), Yonah represents an uncharacteristically large improvement over its immediate predecessor:

• two computational cores with no significant increase in power consumption

The shortcomings of Yonah are largely inherited from previous Pentium M architectures:

• high memory latency due to the lack of on-die memory controller (further aggravated by system-chipset's use of DDR-II RAM)
• poor Floating Point Unit (FPU) throughput due to the smaller number of FP units in each CPU core.
• no 64-bit (EM64T) support
• same or even slightly worse "performance per watt" in single threaded applications compared to its predecessor.

The Yonah platform requires all main-memory transactions to pass through the Northbridge of the chipset, increasing latency compared to the AMD's Turion platform. This is a weakness shared by the entire line of Pentium processors (desktop, server, and mobile.) However, application tests show that Yonah's L2-cache system is quite effective at hiding main-memory latency from the execution core, thus diminishing the impact of that latency on real-life performance.

Many feel that Yonah's lack of 64-bit support will be a significant limitation in the future. However, support for 64-bit operating systems is currently limited in the consumer retail market (the only available consumer retail fully-64-bit operating systems include Windows XP 64-bit Edition and Linux distributions; the only 64-bit applications that Mac OS X v10.4 supports are command-line). This situation is unlikely to change until the releases of Windows Vista and Mac OS X v10.5 in 2006-2007. Also, few laptops support more than 2 GB of RAM, negating the 64-bit's large physical address space capability. Hence, for its intended market (mobile and laptop PCs) the lack of EM64T appeared inconsequential at the time Yonah was released.<
