So now SandyBridge and Bulldozer both have 256bit FPU per core, by SB its native 256bit that can split into 2x128bit while by Bulldozer its 2x128bit that can combine into 1x256bit (per core). intel's SB has a operation that can split it, while AMD's Bulldozer has a native "core" for each 128bit instruction (those 2x128 fpu processors per core). So in reality AMD's 8core bulldozer is a fake 8core with 2 cores per core, but its more of a real core then intel's Hyperthreading.
And this can help allot in games that rely on 128bit FPU, now it can do 2x128bit SSE executions per cycle instead of 1 and like i said this is a nice boost. Not exactly 50% but in some cases it can be as much as that.
For example X3 Terran Conflict (single threaded app.); 1st test - Scene "trade" minimum fps:
my Q9450 (with 1x128bit) @ 3.6ghz: 22fps
i7 2600k (with 2x128bit) @ 4.6ghz: 35fps [yea its 1ghz higher, but you can see how inefficient it is, when it comes to single threaded app, if it were 1:1 i sure it would have only around 30ish fps]
hopefully AMD 8150+ (with 2x128bit)@ 4.6ghz : 50-60fps
if it manages that then it will be a beast of a cpu, most say AMD's 8150+ will suck in single threaded apps, but i have a different pov.
Although yea now that i think again this is not exactly what thread start had in mind, but maybe he got a flash and mixed these two things a bit..
Well I hard about this 128bit processor once (idk 2yrs ago) and that its gonna be in win8, but now its all false. imo we will need another 5-7yrs or so until we will see such tech.Edited by TheHunter - 7/20/11 at 11:30am
