Tech concepts we need to correct ASAP

kareem_nasser

One of them is simple: Having a gfx card with a 1GB GDDR3 RAM doesn't necessarily mean better than an 800MB GDDR3 RAM it is the GPU which really matters and having a high resolution needs more RAM also more Anti-Aliasing needs more RAM at the same time they need more processing power. And as we know the lower the resolution the more Anti-Aliasing we need so which is really confusing that once you switch to your GPUs highest supported resolution, and some games still suffer from Aliasing so you'll need to increase or turn on the Anti-Aliasing feature which means more GPU heat and RAM consumed and as we know the frame rate will drastically decrease sometimes rendering the game totally unplayable.

Another issue is that ppl in Lebanon want HDTVs and they want it Full HD becasue of the higher number(1920*1080) but no local channel supports such resolution or the cable guy gives you the old RF cable which gives the oldest and worst picture quality. That's why we see the screen pixelated becasue it needs to be upscaled and processed which leads to a crappy display.

Do you have another tech error in concept you want to correct?

Actually you as well need to get something straight: It's not only the VRAM and the anti-aliasing that matter, but also what version of Pixel Shader and some other stuff I cannot remember right now. Those are what really matter and what makes a certain GFX card good enough to play games on or not.

P.S: I will try to get back with more details when I get some time, I have to go now.

kareem_nasser

That IS what i am trying to prove but just telling ppl what is a VRAM and Anti-Aliasing to them.
because most or all my non-geek friends just say directly when asked that an HD4000s 1GB VRAM is better than 260 GT 800MB..... :(
I mean i couldnt just say you need to have HD5000 series with Unified Shader Architecture (or Pixel Shader if you want) version 5.0 to get the best gfx. Seriously till now what is the best game(or app) that uses 100% multi-cored CPUs? So they aren't really using the GPU to its full potential only after months or even more of its release.

Those are what really matter and what makes a certain GFX card good enough to play games on or not.

I am not talking about the best GPU to choose it is only just to correct wrong concepts like: Big Numbers....Shiny Lets buy

lol some ppl compare a Nokia 3500c to a 6300 becasue the pic is better or more Megapixels while the real thing is the Bits/pixel which is 16 or 18 bits/pixel(i don't remember) on 6300.
I wish that we teach each other here too. :)

Whenever i want to lookup a video card i look at this list and start to compare

Yeah same here but i follow the citations mostly. But not all know what they mean and what can they but for their needs.

The thing that annoyed me the most is how they used to bundle the newest CPU, a couple of years ago, with 256mb RAM. People would shell out extra buck to get the faster model, but will keep the 256MB RAM default. and sometimes it was a 1 256MB board on a dual-channel controller!!
The reason was obvious, the majority of people, when buying a computer would only look at two thing: CPU frequency and the "Intel Original" logo, so assemblers, in an ugly display of greed, would bundle the fastest CPU with a crappy hard drive and the absolute minimum of RAM... That doesnt make any sense from the technical standpoint, for normal computer usage. For any non-technical folks who might be reading this: this is like assembling a powerful sports car but fitting it with extra-thin cheap tires to cut the cost a little bit.

kareem_nasser

Good point rofl even now ppl who say that they know pc stuff want me to buy "Intel Original" and they dont know what is EVGA or Gigabyte.
As for the CPU it is well known in Lebanon that more Hz=faster PC they didnt notice that most CPUs range from 2.4 till 3.2 GHz the last ten years.... they want a 4GHz?
Then they fight me that a 3.2 Pentium 4 is faster than a Core-i7 2.66GHz

The random-ass use of the word "virus". It's like, whatever goes wrong in a PC, it must be a "virus". There is no such thing as a hardware malfunction.

An example of the Lebanese virus syndrome : the immortal "el computer 3inde sayir ktir bati2, fi chi mit alf virus". Yeah you morons, it's the "virus" slowing down your PC, not the shitloads of useless random software that get accumulated and simultaneously load on startup, eating the memory away (especially on lower end pc's).

You cant really blame these people, its just not their thing. Stores try to mess with their minds and they believe them, its not their fault. Its up to people like us to guide them through choosing the right components at a fair price and educate them about the computers theyre using.

I usually do that, but i end up explaining the whole thing like 10 times till they understand it wrong and i give up explaining in the end. Happened to me with a girl i know that gave me her laptop to try and make it "Fast" :P. Explaning why its necessary to add more RAM and after the explanation she asked me what is RAM.
Girl: Teb shou l RAM ba3ed ma fhemet
ME : FFFUUUUUUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!! :@ :@

Agree with you 100% , I hate it when people call a windows based machine a PC and a Mac one a Mac, Macs are also PCs! i.e. Personal Computers hehe

How about this:

In my Programming Concepts class (which is basically C), a girl asks my friend (Nour)...

*Girl: What's the difference between scanf and printf?
Nour: scanf is for inputting data from the user, while printf is for outputting a msg to the user.
*Girl: but why do we sometimes use scanf with printf and at other times we do not?
*Nour: ... :| omg! well... that's because when you want the user to input something, you have to give him a msg telling him what to input!!
*Girl: ahhhhhhh! How do you know all this stuff? Did the doctor explain them in class? Or have you taken an programming courses before?
*Nour: ... :)

That's only one example of what goes on in class...

I have another story from my college days, from a programming class:

- The teacher: blah blah input blah blah forms blah blah... and this is your assignment. Once you are done, zip it and send it to me through the blackboard.
- Some student: Sir, how do we zip files?

... follows 5 minutes during which the teacher explains to the attentive student how to right-click on the file, click send to archive, etc...

As long as we're on the subject is it normal that in this day and age Winzip still comes in a paying version?

I'm not blaming them, I'm answering the thread's question.

i use 7zip (even better than Winzip) , open source all the way . :)

rolf

I use winRar and always click through the "register" box. It's a minor annoyance. Windows also have (badly) implemented zip folders into the explorer, so who's gonna buy winzip...

Edit: Winzip is a "corel company", so I guess they were swallowed. And they probably kept it because of the name and the history and some customer still pay because of the support I guess.

It's also funny they got to version 14 :)

You may be surprised, but technically it's faster :)
i7 is more like driving a train with multicompartments and runs on more than one track (4 to be exact)

Of course it is but not to the non-geek ppl who think that it stop the PC from freezing.
And if you have the ability to cool a 4GHz overclocked PC be my guest. At the same time it does offer more bandwidth.
But i would like to ask a question: if you have a PC hardware (GPU or CPU) with a Memory Bus Width 64-bit(read&write) and clocked at 1GHz while another is 128-bit(read&write) at 500MHz, By calculation(Theoretically) they are the same but what is the difference?
To be more specific let them be for the CPU and DDR, to make it simple becasue on GPUs it is different.

I am actually laying the blame on both the people and the system integrators (computer shops, in plain English). I blame the people for not doing just a little research instead of falling fur such marketing slogans. I do not have a bigger brain, and nobody came and taught me this stuff, I actually bothered to look it up (mostly on Google).
And I also blame the computer integrators for being so cheap and pathetically trying to screw people with the computing equivalent of laying the biggest, freshest tomatoes on the top of the box.
