And telling people, they have to buy AMD, is no terrorism?
Power consumption is a matter. I live in Germany, I pay 0.25€/kWh (~0.338USD). I did many calculations on currently (say: august until mid of october) available data, including the first BD-benches on those "bad" sites (anadtech, tomshardware etc.) - Taking the (at that moment) current workload, only the additional costs for electricity would give me a new SandyBridge i7, if things get worse even a i7 + Mainboard! This calulation was done for the usage time of 5 years (that's the minimum). So running the SNB for 5 years instead of BD gives me a new CPU for free! This calculation was based on the hope, that I would get a AM3+-Board with onBoard-GPU. As there is nothing like that ATM, There are further €30++ for a dGPU, further costs for power consumption. The i7 95W TDP are CPU+GPU, BDs 125 are CPU-only. So there are not only 30W more on the BD-side (read: by TDP, the actual plus in consumption is a different story), but >50W (depending on the GPU chosen).
And saying "hoo, the rest of my household appliances isn't powerefficient, so buying a power efficient PC is useless" is sort of stupid. If I can save good money with only one machine, I will do it.
BTW: 3000W for your oven is quite a lot. Mine (a Miele) uses 1000W, only takes ~5min. from 20°C to 250°C, and the big rest of the usage time it "idles". Using SB instead of BD gives me 1-2 big loafs of bread (self-baken) per week for free - incl. ingredients.
And now, I stop this useless discussion. Never wanted to start a flamewar, my first post in this thread was only about the uselessness of both "benchmarks" (running only one app vs. running as many CPU/GPU-intensive tasks as you can). It was last year, when I said, I need a new PC in 2011. All the months, I said "wait for BD...". BD was not what I expected, so I went for SB... i7 for 245€, and BD? 230€ for the 8150. And it is not available. So even if I would have gone for BD, I would not have been able to buy one... (Only the 4100 is available here, some shops also offer the 6100. All others are "Ohne Liefertermin"). It was my decision, I am happy with it, nevertheless I will recommend AMD-based systems when it is appropriate.
Nice one, buddy. You found a mobile part with both enabled, and it's just barely under $200. I was using the logical choice, the Core i5 2500 desktop part as a point of reference. I wonder how much research you had to do to figure out that some of those mobile parts did have both enabled? At any rate, being a mobile part, the laptop vendor will probably take the liberty of disabling that VT-whatever for you, and removing the BIOS option to enable it, so it's kind of a moot point. Let's stick to desktop CPUs.
You're a fool. Read the fucking page I linked you. Socket 1155 which is *gasp* a desktop part!
An input/output memory management unit (IOMMU) enables guest virtual machines to directly use peripheral devices, such as Ethernet, accelerated graphics cards, and hard-drive controllers, through DMA and interrupt remapping. This is sometimes called PCI passthrough.
And get the k model, lose VT-d. The normal virtualization stuff is now mainstream enough for Intel to not remove it from random CPUs it seems, but for what is VT-d useful/needed?
I really don't remember. In some cases I think there might have been performance hits using it. I can't site a source off the top off my head though. We aren't here to learn though, we're here to be pedantic and condescending. Stick to the guidelines.
