sapphire is the premium brand for AMD cards. they generally measure up to the quality of MSI or ASUS cards (and sometimes exceed them). I was recently informed a sapphire direct CU 7850 do not have ANY heat-spreaders on the memory chips or the voltage regulators and feel that ASUS is just riding on their reputation and slipping...
the special thing about sapphire is their toxic and atomic editions of AMD cards. they take it much farther than any other vendor and really make extreme editions of AMD's flagship cards (just check sapphire toxic 6970 or the up comming 7970 toxic). the only company that comes close are ASUS's ROG edition cards
Interesting.. I just checked to compare some brands for any who are interested in what I got in terms of raw numbers. :3
All of the following brands made this card with their respective speeds: AMD Radeon HD6770. Please keep in mind, the Gigabyte model is NOT silent cell, its the D5
Asus: Core: 850MHz, Memory: 4000MHz
MSI: Core: 800MHz, Memory: 4400MHz
XFX: Core: 850MHz, Memory: 4800MHz
Gigabyte: Core: 775MHz, Memory: 4000MHz
Sapphire: Core: 850MHz, Memory: 4800MHz
HIS: Core: 850MHz, Memory: 4800MHz
Powercolor: Core: 850MHz, Memory: 4800MHz
Stock: Core: 900MHz, Memory: 4200MHz
Pretty interesting, eh? Im a little curious as to why everybody took AMD's reference card and knocked them down in clock speed and then for the most part boosted the RAM.
What makes me angry is that Gigabyte brought the core down from 900MHz to 775MHz FOR SOME REASON, and then cut off 200MHz from the refference, which isn't too terrible. But Why the hell did Gigabyte limit the card so darned much? >:I I'd say that from the looks of it, XFX and Sapphire in his case are the best options to go for. Though, on the bright side I've heard of people successfully overclocking their Gigabyte (GV-R677D5-1GD) up to 910, which means that its effectively 10MHz faster than the refference. Pathetic. Imagine what that refference card could do D: . Im willing to bet that the "overclocking" you do with these graphics cards are mostly phony values. I think its just companies that design the card to run at a faster speed, set the default down, and then let you turn up the speed dial back to full speed and this lets the user feel powerful, like they overclocked and are squeezing the jucie out of the card when, all theyre REALLY doing, is making the card run like it was designed to. This "overclockability" room lets them jack the price and market as a good overclocking card. Thats ofc IMO, but I think its pretty damend solid. On the other hand, RAM and CPU's I have NO DOUBTS what so ever that all overclocking on those are completely legitimate pushing of the limits. I feel kind of pissed off at all of the brands that take from AMD and re-sell with their own hardware. Especially Gigabyte. I heard that Gigabyte is amongst the best of them all, and the way they've manipulated the product kind of disgusts me. Depending on how this card "overclocks", and by overclocks I mean how well it comes close to running the real default speed of the core, and by the performance of the card, I might just abandon Gigabyte and stick to XFX, Asus, or Sapphire.
