Sapphire Radeon HD 7950 Mac Edition Pictured
Sapphire unveiled the Radeon HD 7950 Mac Edition graphics card for Apple Mac Pro workstations. Featuring lateral-flow cooling assembly akin to AMD's reference design, and a glossy, curvy white cooler shroud, the card features a custom design, pitch-black PCB with the firmware required to get the card running on a Mac Pro.
The card features older Radeon HD 7950 ASIC, which lacks PowerTune with Boost; and features clock speeds of 800 MHz core, 5.00 GHz memory. It packs 3 GB of memory across a 384-bit GDDR5 interface. It draws power from two 6-pin PCIe connectors. Display outputs include a dual-link DVI, an HDMI, and two mini-DisplayPorts. The card is expected to be priced in the range of €400 and €500, a hefty premium over the roughly €250 common HD 7950 cards charge today.

cost-push - apple probably charges high royalty or whatever licensing fees.
superior product - in economic terms, it is based largely on what the consumer view as premium products
competition - do i need to even explain?
This price is largely due to a economist or statistician somewhere with their charts and equilibrium. Since demand is small but constant, they can adjust the price by limiting supply and use their brand premium. As there is very little cost incurred by apple, they would be smart to keep the price up as it keeps their image up. Keep the supply down so you don't saturate the market and cause a surplus. The less apple products that end up at a discount store like TJMaxx, the better the brand image.
1st year all good unless your a moron the computer ran fast and stable.
2nd year by the end of the year there were a bunch of HDD crashes and a computers froze running firefox + word almost every class we used them. The batteries were at 0-20% at the end of the day.
3rd year even more HDD crashes speed was abysmal running the same software as before many batteries were dry by the end of 3rd period. At the end of the year the school got rid of them and bought a new batch.
These computers were cleand and had their OS+software reinstalled at the end of each year.
In the highschool we have to use them and here's a list of common problems:
wobbly screens, dry batteries, serious graphical artecafts in some games, RAM hogging (I had 6.4GB of used ram even when I had no apps open),MS Word causes lag, HDD crashes, overheating when running internet (seriously I use a fan controller and at 91% speed I had 60C typing this while listening to music from Youtube). BTW this is the 2nd year that high schoolers need to use mac laptops next years gonna be a practical demonstration of why not to buy a mac
That said, I don't see a ton of PC hardware repairs either because these people are mature adults, first and foremost. All computers in school lab environments get thrashed, especially middle and high school. Even worse when they can take them home.
These are laptops correct? Having hard drive issues is common in laptops as they are mechanical by nature. Apple uses Hitatchi, WD and seagate for their drives. All of them just have an apple logo and serial number on them. How old are these machines to begin with? Hard drives usually fail within 2-3 years.
How do I know this? Because I repair macs for a living. Hard drive failures are the most common repair. Actually, they are the most common repair out of any repair I do on a macs. The PC tech I work with? Viruses, then hard drive failures are his most common repairs.
3rd year even more HDD crashes speed was abysmal running the same software as before many batteries were dry by the end of 3rd period. At the end of the year the school got rid of them and bought a new batch.
This is because again, these machines are in the hands of students, thrown onto desks (not literally), put into backpacks, moved around a lot. After going through this, it is not surprising to see hard drives fail. Hell, any machine would have a hard drive fail in conditions like that.
wobbly screens
I take it these are unibodies? The hindges are screwed onto the clamshell and top case. The screws work themselves loose from opening and closing of the clamshell over time. Screws just need to be tightend.
Dry Batteries
Most batteries have a life cycle of 1000 charges. That is easy to do in a year or 2.
RAM hogging
Just because the RAM is being used doesn't mean that it is being used if that makes any sense. OSX will use as much RAM as it sees fit to run itself and programs properly and will dynamically unload RAM as needed. It also likes to do a lot of caching so programs that were previously used load quicker. Windows does the same thing. I have 16GB in my sytem and right now have 6.2GB used. That is just sitting here with Chrome open.
MS Word causes lag, HDD crashes,
This is probably because of the hard drive. High schoolers (not you, but those who used your machine before you) are rough on machines and beat the hell out of them. Most kids are rather dumb when it comes to their machines because they are NOT theirs. If something isn't yours, do you think you treat it with the same respect as something that is? Nope.
overheating when running internet (seriously I use a fan controller and at 91% speed I had 60C typing this while listening to music from Youtube).
Macs do tend to run hotter than PCs because of their design, but this is not really an issue. They are programed to run hotter to produce less sound. Plus, it is likely the TIM needs to be reapplied and heat sinks cleared of debris. This is normal for machines that are used a lot like what you are using (I service a lot of school computers). 60C isn't overheating. The processors are designed to run up to 100C. 60C is normal for a laptop. Especailly the Core 2 Duo machines you are likely running. And youtube? It is surprisingly CPU intensive and GPU intensive (2d processing). That is why I use it for testing (20 youtube windows up at a time and let them go :D).

The fact that these macs are going through hell of you kids and still working is a testament to their durability.
I work as an ACMT (Apple Certified Macintosh Technician) for a local AASP (Apple Authorized Repair Center). Each month I get about 400-500 machines in (I am the primary mac tech and do about 70% of the repairs myself). Most of the time what I am fixing is stupid software crap or someone has a failed hard drive in a machine that is going on 4 years old.
BTW, I have a macbook pro early 2008 17 still going strong. The only thing I worry about is the nvidia issue the logic board on these guys have. I know I will have to replace the logic board at some point. But until then, she is still kicking butt.
Another comparison that can be made here is what makes an enterprise class drive more expensive? They are the EXACT same drives (7200RPM ones) as their consumer counter parts. You know what makes them so much more expensive? Their firmware. It has the obvious things like no spindown and error correction, but there is one other thing that makes them cost more. The algorithms used to compensate for vibration. Consumer drives don't have this.
For these cards, they may be exactly the same as their counterparts physically. For this case, they have powertune and boost turned off (that is easy to do). But writing firmware for something specific is different. The firmware has to comply with something that OSX uses called DSMOS (Don't Steal My Mac OS), which is the authorization system used to check the hardware during boot to make sure it complies with apple.
Consoles, PCs, Macs, Servers, tablets, and phones.
Price doesn't matter. What matters here is that Apple also has AMD.
Wrap up old generation hardware in a pretty white bow and sell it 25% above the msrp and they with follow.. :slap:
Some of the "problems" people have with Apple itself are much more legitimate, however they rarely do things most other companies don't (or wouldn't in the same shoes). The worker suicides thing is a classic example. People screamed "Apple is evil!" when it was at Foxconn who makes parts for damn near everyone, for Christ's sake.
