Agreed, he is full of shit.
lol me cague de risa, hablo español, hay algo en la palabra "potato" que me hace reir mucho en cuanto hardware se refiere
The 270X with tuning will also go up, so I'm not sure what you're trying to point out. With both at stock, they're both 180, as provided by AMD.
7950 with tuning has 250 W
i don't believe you)) my 7950 can work wihout increasing voltage only on 1060 mhz ( it's on 1094 mv), Asus Gaming card
i have a 7950 at 1150 mhz without increasing voltage so now the 270x is way slower
My computer: Processor: Intel Pentium potato 0.01ghz Video card: nvidia potato 1kb vram ram: potato 1kb hard drive: potato -1 rpm 2kb (You speak spanish? pues yo si hablo español :V)
Which card can overclock higer? In 7950 we can put bios from 280 model, they are the same, instead clock and we have 133 mhz change without voltage change.
They're both 180 W.
Which card has lower TDP?
A stock 270X anyway. Practically 100% of people who buy the 270X will overclock it.
How is the R9 270X so close to the 7950? Is AMD tweaking the drivers? Maybe this is why artifacting is common with AMD cards. AMD just cares about bench scores and to heck with your screen going nuts LOL.
overclock and u have a 270x now
I bought a HIS R9 270 iPower IceQ X² Boost Clock 2GB for $179, It is a great card I love it, But today I found A $219 Saphire R9 270X 4GB model on newegg for just $40 dollars more than what I paid for my R9 270 nonX 2GB. Oh well I need to just be thankful for what I have. It is still better than my old GTX 650 Ti 1GB and Better than the GTX 660 and GTX 750 TI.
The HD 7950 by about 3% in benchmarks. In games, they're pretty much the same.
Who is the winner?
