Intel GMA 950 in the Mac Mini
new Mini with Intel GMA 950 + WoW = ??? - Mac Forums
By all accounts the new Mac Mini is a great unit but there is a downside. In order to cut costs Apple have used an intergated graphics chip the Intel GMA 950. This means that the Intel Mac Mini will be a dog for games. With the form factor on the mini there is no way to upgrade.
That said who's going to buy a Mini to play games? As long as it plays back HD video well then it'll be a hit.
Another area to consider is that a medium to high-end graphics card would produce a ton of heat. That heat would be a real problem inside something as small as the Mini. With the Core Duo producing more heat than the G4 chip Apple obviously needed to make some changes in order to keep the overall heat envelope down. Add to that the addition of a faster HDD, the new Mini uses a 5400 or 7200 HDD which also produces more heat.
