celeron M vs. centrino M

Que tal

Espero que alguien me pueda ayudar en mi predicamento. Tengo una laptop con un procesador Celeron M de 1.5gHz con FSB de 400mHz y caché de 512KB. En general sirve muy bien, no tengo quejas, pero me ofrecen un centrino M de 1.5gHz.

Tengo entendido que el centrino incluye un pentium M y que este modelo, que ya es algo viejito, debe tener una caché de 1MB, el FSB me dijeron que también es de 400 mHz.

Quiero usar la laptop para editar videos familiares, entonces mi pregunta es: ¿vale la pena el cambio? ¿si obtendré un mayor rendimiento en los procesos en general?

Estuve consultando en algunos foros, donde algunos dicen que el celeron M era una gran inversion y que no le pedía nada al pentium M, otros decían que el celeron era el peor error de Intel. Y en cuanto al centrino solo decían que tiene un excelente manejo de la energía, lo que se traduce en un rendimiento mayor en la batería, aunque a mi el rendimiento de la batería realmente no me interesa en lo más mínimo.

¿Así que qué dicen? ¿Vale la pena?, el procesador me lo dan a un equivalente de USD $80, y lo estoy considerando ya que hace un par de meses me vendían un pentium M de 1.5gHz en el equivalente a USD $250

De antemano gracias por la ayuda que me puedan ofrecer.

Saludos desde México. Cool

No entendí muy bien cuanto te está costando el cambio.

Ahora, de todos modos, unas cositas para alcarar.
Centrino no es el nombre de un procesador, sino de una tecnología. Es como un ¨paquete¨de features que traen todos los sistemas Centrino, como ser módulo WiFi, ciertos chipsets de intel, y alguna otra cosa más.
Puede ser Centrino, pero el micro puede ser Pentium M, Core Duo, Core 2 Duo y no se si también las versiones single core, así como también los nuevos Pentium DualCore ( que en el caso mobile no es más que un Core Duo recortado).

Bueno, ahora, el Celeron M es directamente el micro económico del Pentium M, o sea que estás en la misma generación. Por lo que pude ver, la diferencia está en que el Celeron M tiene 512KB de cache contra 1MB del Pentium M, éste último soporta SpeedStep (el cambio de la velocidad del micro mientras corre, esto hace que pueda consumir menos batería) y el hecho de que viene con el ¨paquete¨Centrino. En esencia no es la gran diferencia.

Me parece que salvo que el costo sea realmente bajo, no tiene mucho sentido el cambio, o sea, si el Celeron M te sirve bastante bien, quedate con ese o sino invertí en algo más groso.

Gracias por tu respuesta Bioti.

El Centrino que me ofrecen tiene un pentium M, supongo que es de los primero que salieron de este tipo.

En cuanto al cambio de frecuencia que comentas, mi laptop de repente no se le oye para nada el ventilador del disipador, pero cuando estoy en tareas pesadas, como juegos o ediciòn de video, luego luego se oye como el ventilador comienza a girar velozmente, aunque no siempre es así, ya que en ocasiones se nota como se acelera el ventilador levemente, podría decir que se escuha como en 4 velocidades diferentes; ¿algo así es lo que hace el centrino M?

y otra pregunta ¿el aumento de la caché L2 de 512MB a 1GB no beneficiaría sustancialmente?

Estoy de acuerdo con Bioti: no creo que valga la pena el cambio a menos que el costo sea muy bajo (U$S 30 o 40). Es cierto que hay una cierta diferencia por esa cantidad de caché, pero no es tan grande como para justificar un gran gasto de dinero.

Por cierto, me parece que los que dijeron que el Celeron fue el peor error de Intel (?) se referían a los procesadores para PC de escritorio, que no tienen nada que ver con el Celeron M ya que están basados en la arquitectura de los Pentium 4 (distinta a la de Pentium M).

Claro, se suele decir que el Celeron es de lo peor, sobre todo porque su contraparte, el Duron y el Sempron, en general tienen menos recortes en comparación a los Athlon que los Celeron con los Pentium, y porque eran mucho mas ovcerclockers, entonces la diferencia entre un Duron y un Celeron era importante.
Los Celeron M son Pentium M recortados, y los Celeron desktop son P4.

Gracias Bioti y GenAris, ya con lo que me dijeron quedo complacido y creo que, como GenAris, si hago el cambio esperaré a que haya una mejor oferta (osease que mas barato).

Saludos,

President Barack Obama, under growing criticism for not seeking to end the ban on openly gay men and women in the military, is extending benefits to same-sex partners of federal employees. Obama plans to announce his decision on Wednesday in the Oval Office, a White House official said Tuesday. The official spoke on the condition of anonymity because the president hadn't yet signed the presidential memorandum.
The official said Obama would release more details on Wednesday.
The decision is a political nod to a reliably Democratic voting bloc that in recent weeks has grown frustrated with the White House's slow movement on their priorities.

Several powerful gay fundraisers withdrew their support from a June 25 Democratic National Committee event where Vice President Joe Biden is expected to speak. Their exit came in response to a June 12 Justice Department brief that defended the Defense of Marriage Act, a prime target for gay and lesbian criticism. Justice lawyers argued that the law allowed states to reject marriages performed in other states or countries that defy their own standards.
The legal arguments -- including citing incest and sex with minors -- sparked rebellion among gay and lesbian activists who had been largely biting their tongues since Obama won election. They had objected to the Rev. Rick Warren's invitation to participate in the inauguration despite his support for repealing gay marriage in California.
Their January protest won the invitation of Episcopal Bishop V. Gene Robinson, whose consecration as the first openly gay bishop divided and almost split his denomination.

Gays and lesbians later fretted as the White House declined to intervene in the cases of enlisted military members facing courts martial for defying the Clinton-era ''don't ask, don't tell'' policies. White House officials say they want Congress to repeal the policy as part of a ''lasting and durable'' solution, instead of intervening on individual cases.

''The president agreed that ... the policy wasn't working for our national interests, that he committed to change that policy, that he's working with the secretary of defense and the joint chiefs on making that happen,'' White House spokesman Robert Gibbs said last month.
In the meantime, the administration has tried to make small, quiet moves to extend benefits to gays and lesbians. The State Department has promised to give partners of gay and lesbian diplomats many benefits, such as diplomatic passports and language training.
last chaos gold
But without a specific change in the Federal Employees' Health Benefits Program, Secretary of State Hillary Rodham Clinton's promises left out financial benefits such as pensions. Obama's move could make that shift.
Gay and lesbian activists had expected Obama to take action some time in June, which is gay pride month.
John Berry, the highest-ranking gay official in the administration and the de facto human resources chief for the administration, told a gay rally last weekend that Obama planned to take action on benefits soon.
Berry, who heads the Office of Personnel and Management, has repeatedly told reporters that he expected the White House to turn to legislation to give domestic partners access to federal health and retirement plans.
But Obama so far has sent only one piece of legislation to the Hill -- a pay-as-you-go measure that is part of his wooing of fiscally conservative Democrats.

Instead, Obama will use his signature instead of legislation to achieve the benefits parity sought by same-sex couples.

Jacob Have I Loved
Our story is called Jacob Have I Loved ,by Katherine Paterson. It received the Newbery Award for the best book written for young people in the United States. The story takes place on Rass Island in the Chesapeake Bay along the eastern coast of the United States, near Maryland and Virginia. The story is told by Sara Louise Bradshaw, a 13-year-old girl who lives with her parents and her twin sister Caroline. Here is Gwen Outen with the story.
wow power leveling,
Rass Island lies as low as the back of a turtle on the dark green water of the Chesapeake Bay. We Bradshaws have lived here for more than two hundred years. I love Rass Island although for much of my life I did not think I did.

During the summer of 1941, every morning McCall Purnell and I would get my small boat and go out to catch shellfish called crabs. Watermen on our island sell crabs and eat crabs. Call and I were right smart crabbers and we could always come home with a little money as well as crabs for dinner. My mother was pleased with money I made.

"My!" she said, "that was a good morning. By the time you wash , we'll be ready to eat!" I like the way she did that. replica rolex,She never said I was dirty or that I smelled bad. Just by the time you wash up.

She was a real lady my mother, she had come to teach in the island school and fell in love with my father. What my father needed more than a wife was sons. What my mother gave him was girls--twin girls! I was older than my sister by a few minutes. I always treasure the thought of those minutes. They were the only time in my life when I was the center of everyone's attention. From the moment Caroline was born, she took all the attention for herself. When my mother and grandmother told the story of our births, it was mostly of how Caroline had refused to breathe.

"But where was I?" I asked my mother. replica rolex,
"In the basket," she said, "Grandma dressed you and put you in the basket."

Caroline's true gift was her voice. Our teacher, Mr. Rice, said she should have singing lessons. I was proud of my sister, but something began to hurt me under the pride.

One day, Mama and Caroline came back to the island on a boat after Caroline’s singing lesson. There was an old man on the boat whom I'd never seen before. Our island held few secrets or surprises beyond the weather. But all the old people agreed that he was Hiram Wallace . My friend Call and I started visiting Hiram Wallace. We decided simply to call him the Captain.

The Captain stayed at our house when the big storm hit in 1942. Afterward, we took my little boat heading straight for the Captain's house. But nothing was left at the spot where the Captain's house had stood the night before. Even with his white beard the Captain looked like a little boy trying not to cry.
replica rolex,
Not long after that, the Captain married Trudy Braxton who lived on the island. She was not well and did not live long. Soon the Captain came up the path to our house, his face red with excitement. He told my mother and me that Trudy left a little money. ''There is enough for Caroline to go to boarding school in Baltimore, Maryland and continue her music.'' said the Captain.

I sat there as surprised as if he had thrown a rock in my face! ''Caroline!''

My grandmother came up close behind me. I stiffened at the sound of her hoarse whisper. ''Romans 9-13,'' she said. She repeated the saying from the Christian Bible about the competition between two brothers for their father's love. ''Jacob Have I Loved, but Esau have I hated''.

I had always believed the Captain was different. But he, like everyone else, had chosen Caroline over me.

In the autumn I left school, I spent the winter catching oysters, another kind of shellfish, with my father. That strange winter with my father on his boat was the happiest of my life. I was, for the first time, deeply satisfied with what life was giving me. Part of it was the things I discovered. Who would have believed that my father sang while catching oysters! My quiet father whose voice could hardly be heard in church sang to the oysters! It was a wonderful sound!
replica rolex,
I did not want to go back to school, so my mother taught me at home. I passed the test for graduation with the highest grades recorded from Rass Island.

The war in Europe ended in 1945. At the end of crab season Call came home from the war. The body of a large man in uniform was filling the door.
''Call,'' I cried, ''Oh my blessed Call, you have grown up!'' ''That's what the navy promised,'' he said.

Call told the Captain he had stopped to see Caroline. His face burned with happiness when he told the Captain ''She said YES to me,'' he said softly, ''I guess it is hard for you to think someone like Caroline might like me.''

I went back to the crab house. Soon after Call and Caroline were married, the Captain said to me, ''This is hard for you, isn't it? What is it you really want to do?''

I was totally empty. What was it I really wanted to do?

''Your sister knew what she wanted,'' said the Captain, ''so when the chance came she could take it. Do not tell me no one ever gave you a chance, Sara Louise. You can make your own chances. But first you have to know what you are after, my dear.''

''I would like to see the mountains,'' I said, and then my dream began to form along with the sentence, ''I might, I want to be a doctor.''

''So what is stopping you?'' the Captain asked.
replica rolex,
I realized that under all my dreams of leaving home, I was afraid to go. My mother had told me that she had chosen to leave her people and build the life for herself somewhere else. ''I certainly would not stop you from making the same choice,'' my mother said to me now, ''but all we will miss you, your father and I.''

I wanted so to believe her, ''As much as you miss Caroline?''

A Coke and a Smile

I know now that the man who sat with me on the old wooden stairs that hot summer night over thirty-five years ago was not a tall man. But to a five-year-old, he was a giant. We sat side by side, watching the sun go down behind the old Texaco service station across the busy street. A street that I was never allowed to cross unless accompanied by an adult, or at the very least, an older sibling. (wow power leveling)

　 Cherry-scented smoke from Grampy's pipe kept the hungry mosquitoes at bay while gray, wispy swirls danced around our heads. Now and again, he blew a smoke ring and laughed as I tried to target the hole with my finger. I, clad in a cool summer nightie, and Grampy, his sleeveless T-shirt, sat watching the traffic. We counted cars and tried to guess the color of the next one to turn the corner.

Once again, I was caught in the middle of circumstances. The fourth born of six children, it was not uncommon that I was either too young or too old for something. This night I was both. While my two baby brothers slept inside the house, my three older siblings played with friends around the corner, where I was not allowed to go. I stayed with Grampy, and that was okay with me. I was where I wanted to be. My grandfather was baby-sitting while my mother, father and grandmother went out. world of warcraft gold
　

Thirsty?" Grampy asked, never removing the pipe from his mouth.

" Yes," was my reply." How would you like to run over to the gas station there and get yourself a bottle of Coke?"

I couldn't believe my ears. Had I heard right? Was he talking to me? On my family's modest income, Coke was not a part of our budget or diet. A few tantalizing sips was all I had ever had, and certainly never my own bottle.

" Okay," I replied shyly, already wondering how I would get across the street. Surely Grampy was going to come with me.

Grampy stretched his long leg out straight and reached his huge hand deep into the pocket. I could hear the familiar jangling of the loose change he always carried. Opening his fist, he exposed a mound of silver coins. There must have been a million dollars there. He instructed me to pick out a dime. After he deposited the rest of the change back into his pocket, he stood up. World of warcraft Power Leveling

" Okay," he said, helping me down the stairs and to the curb, " I'm going to stay here and keep an ear out for the babies. I'll tell you when it's safe to cross. You go over to the Coke machine, get your Coke and come back out. Wait for me to tell you when it's safe to cross back." 　

My heart pounded. I clutched my dime tightly in my sweaty palm. Excitement took my breath away.

Grampy held my hand tightly. Together we looked up the street and down, and back up again. He stepped off the curb and told me it was safe to cross. He let go of my hand and I ran. I ran faster than I had ever run before. The street seemed wide. I wondered if I would make it to the other side. Reaching the other side, I turned to find Grampy. There he was, standing exactly where I had left him, smiling proudly. I waved.

" Go on, hurry up," he yelled. cd keys

My heart pounded wildly as I walked inside the dark garage.I had been inside the garage before with my father. My surroundings were familiar. I heard the Coca-Cola machine motor humming even before I saw it. I walked directly to the big old red-and-white dispenser. I knew where to insert my dime. I had seen it done before and had fantasized about this moment many times.

The big old monster greedily accepted my dime, and I heard the bottles shift. On tiptoes I reached up and opened the heavy door. There they were: one neat row of thick green bottles, necks staring directly at me, and ice cold from the refrigeration. I held the door open with my shoulder and grabbed one. With a quick yank, I pulled it free from its bondage. Another one immediately took its place. The bottle was cold in my sweaty hands. I will never forget the feeling of the cool glass on my skin. With two hands, I positioned the bottleneck under the heavy brass opener that was bolted to the wall. The cap dropped into an old wooden box, and I reached in to retrieve it. I was cold and bent in the middle, but I knew I needed to have this souvenir. Coke in hand, I proudly marched back out into the early evening dusk. Grampy was waiting patiently. He smiled.

wow power level," Stop right there," he yelled. One or two cars sped by me, and once again, Grampy stepped off the curb." Come on, now," he said, " run." I did. Cool brown foam sprayed my hands." Don't ever do that alone," he warned.I held the Coke bottle tightly, fearful he would make me pour it into a cup, ruining this dream come true. He didn't. One long swallow of the cold beverage cooled my sweating body. I don't think I ever felt so proud.
