Nvidia introduces the Tegra
Oct 13th
Nvidia today left me wordless! They are jumping in the mobile, smartphone and netbook market in a very “noisy” way.
The NVIDIA® Tegra™ family of computers-on-a-chip, brings the power of advanced visual computing to a broad range of handheld and mobile platforms—from phones, MP3 players, and portable navigation devices (PNDs) to mobile internet devices (MIDs). NVIDIA Tegra enables intuitive user interfaces and advanced multimedia features, all while delivering longer battery life.
This System-On-Chip is a very gigantic breakthrough in the business that involves netbooks, mobile phones, palms, and EeePc-like devices. And Arm11 CPU (implemented by Nvidia itself), with a GoForce graphic chip, plus all the set of hardware needed inside of our current smartphones and handheld devices.

Tegra dimensions comparisons
The size is impressive too and, probably, the more valuable thing. It’s 1/10 of a full system based on Intel Atom (that is only a chip, while this one is a full system). What does it means to be “that small”? It means:
- Ultra-low power consumption
- Ultra-low heating
- Lighter devices
- Cheaper devices
- More space for future innovation
And they did all this with performance (both for quality and speed) that are astonishing. I strongly suggest to take a look to the Nvidia Tegra official YouTube channel.
Curious? Start from the official page.

I’m looking these 2 videos about the Chat between S. Jobs and B. Gates at All Things Digital 2007.
Actually I finished this:

Density is Everything!
Jan 27th

No, stavolta risparmio il mio inglese a chi davvero non riesce a digerirne la malforme qualità (ogni riferimento a persone, cose, animali e libellule è puramente VOLUTO!!!
).
Ma, torniamo alla notizia:
Secondo la famosa rivista scientifica Nature, il Caltech (California Institute of Technology) e l’UCLA (Università della California, Los Angeles) hanno creato quella che pensano essere la scheda di memoria più densa al mondo.
La memoria è da 160 kilobit e ha una densità di 100gigabit per centimetro quadrato.
James Heath, professore di chimica del Caltech, che ha condotto la ricerca, ha detto che ci vorrà parecchio prima che la tecnologia finisca in un notebook. Heath pensa che Intel si interesserà a questo tipo di tecnologia intorno al 2020 (ndDetro: Peccato…) .
I produttori si stanno chiedendo come estendere la miniaturizzazione dei circuiti oltre il 2013 visto che non sono riusciti veramente a trovare un modo di vincere la Legge di Moore.
Mmmm, facciamo 2 conti: Se per 100gigabit c’è bisogno di una scheda da 1cm, vuol dire che in questa scheda ci stanno 100gigabit/8 GigaByte = 12,5GB. Per poter realizzare un disco, che so, dei classici 80GB per Notebook… basta una superficie di… 6,4cm!!! Fenomenale!
Geekbench Comparison: G4 vs G5 vs AMD64 vs P4 vs Xeon
Feb 1st
On Geekpatrol.ca there is a comparison between…
1. Mac Mini 1.42 GHz
* 512 KB L2 cache
* 167 MHz system bus
* 1 GB DDR 333 SDRAM
2. iMac G5 2.1 GHz
* 512 KB L2 cache
* 700 MHz system bus
* 1.5 GB DDR2 533 SDRAM.
3. iMac Core Duo 1.83 GHz
* 2 MB L2 cache shared between cores
* 667 MHz system bus
* 1 GB DDR2 667 SDRAM.
4. iMac Core Duo 2.0 GHz
* 2 MB L2 cache shared between cores
* 667 MHz system bus
* 512 MB RAM DDR2 667 SDRAM
5. Power Mac G4 Dual 1.25 GHz
* 256 KB L2 cache per cpu
* 2 MB backside L3 cache per cpu

* 800 MHz system bus
* 1 GB DDR2 400 SDRAM
… using Geeckbench Preview: a opensource benchmark running on MacOSX and Windows by now.
I’m sure, these tests can’t be called “official” but… give an idea about performances of these processors/machines.
