I suppose there really is no reason to get Bay Trail or Kabini. They're both poor excuses for processors <90
Correct. They're both horrible. That's what I've been saying, so I cannot understand why they're being compared to Pentium and Celeron HASWELL chips in this thread. BT is at least excellent on mobile, while kabini is horrible on both mobile and desktop. The performance deficiency with both Bay Trail and Kabini on desktop is so large that you can't in any way justify a 20-30$ difference for such a huge difference in performance. Some may argue the power angle. Well, as i've already discussed, the power difference is meaningless because all of these CPUs are sub 55W TDP; you can run all of them with a 300W PSU. This isn't a dGPU situation where the power ranges can be vast from 60W to 500W. It's not like that. All of these CPUs (BT, Kabini, celeron, pentium) are close and therefore it doesn't matter. Or the other power argument. Heat and noise. Some dGPUs can be hot and loud, case in point, reference GTX 480 or reference 290X - this is as a result of significantly high TDP and/or cooling solution used. This DOES NOT APPLY to any of these CPUs, so heat and noise is simply not a consideration. All of these CPUs are quiet, are sub 55W TDP, and can run off a 300W power supply. Trying to argue the power argument by TDP or heat/noise in favor of Kabini is lunacy, because all 4 of these chips are close to each other. Now the Bay Trail can be fanless to my understanding. Still, that does not in any way shape or form warrant the performance deficiency (as is the case with Kabini as well) given the minor price difference.
Now bay trail was designed for mobile. And it excels there. But it sucks on the desktop. Kabini? Same story, although it isn't good for mobile either. It sucks for desktop. It sucks for both mobile and desktop.
There is no situation in which anyone can make a compelling argument for Kabini in comparison to Haswell pentium or Haswell celeron. It's a joke that it is even being mentioned as a viable alternative in this thread.
Now I was unaware that some FX6300 boards had IGP graphics. (does anyone have BENCHMARKS on these motherboard IGP graphics??) Most do not. Still, microcenter does have combo deals on pentium and celeron. So if we go that route, we can easily find scenarios in which the pentium or celeron are better and cheaper. That said, the FX6300 is certainly a better comparison than the Kabini. The Kabini is not a good desktop CPU in any context. FX6300? It can be a good viable chip. Same for the 760K. It is generally more expensive, however. These are all pretty good budget CPUs. Kabini and BT are not good budget CPUs, even if they're 20-30$ cheaper.
The performance is simply god-awful for a desktop platform. Compounding matters is the fact that most of these motherboards either do not have or do not support full PCIE x16; on some of these boards you either CAN'T add a dGPU or even if you did, it would not help performance. You can find dGPU + Kabini desktop benchmarks in which the dGPU made almost zero difference. Conversely, you can create a VERY GOOD gaming machine with a Haswell Celeron / Pentium with a dGPU. PCPer put up an article on both AMD and intel based sub 550$ gaming PCs. They're quite capable for NOT a lot of money, even for PC gamers. Or if you want to roll with AMD. Now on average the 760k or FX6300 platforms will cost a bit more, but you can still make pretty good budget gaming PCs with these CPUs. Kabini and BT? They're a no-go.
As far as tax goes, i'm sure the golden age will end at some point. The vast majority of states do not require internet sales tax. Californians of course always get the shaft the worst when it comes to these things. Uncle Sam will get his if he wants it, and it seems that more states are wanting to get their share. Luckily, for most states they can get tax free PC gear from newegg along with free 2 day air shipping. Not a bad thing since newegg has pretty deals now and then. MC is good as well, however there is simply no way around the sales tax at MC.
