    Case inluding P/S starts at 30, that's below $42 currently, including 19% VAT. So including that Kabini board, depending you get it between 30 and 100$, sums up to below 75 ... below 145$. Unfortunately the Kabini ITX boards aren't sold in Germany, so it's all just theory.

    Intel NUC starts at 115 ≃ $158 here (incl VAT)

E1-2100 has two cores with just an 128bit Fmac vector per core (1/4 of the FX Cpu) and just 2dmips/mhz core at 1ghz, that is just 4000dmips. Core i3 has 2 cores * 10dmips/mhz per core * 3ghz, that is 60000dmips. Just 15x difference, but your benchmarks show 2.5x, so???
      You're making the assumption that every program consists only of vector instructions that use this unit. That's probably not the case. Also, memory subsystem, branch mis-prediction, and other bottlenecks can reduce peak performance. I'm not saying that there couldn't be a higher difference in the benchmarks, but pure theoretical peak numbers almost never reflect reality.

        All these synthetic benchmarks don't say much to me.Wuld be nice to have some subjective commentary on real wotld performance. How does play back 1080p flash? What's browser performance like?

          Also 1990s called, they want their USB 2.0 technology back.


          http://www.mini-box.com/picoPSU-80 $25 ! these work quite well


          complaints about USB3 is foolish... its not just a simple "bam, upgrade your ports to 3.0", it takes BANDWIDTH from the chipset (inside the apu). In this case, this dual core doesn't natively support USB 3.0, the rest of the G-Series Kabini APUs only have 2. http://www.amd.com/us/Documents/AMDG...oductBrief.pdf (G-series == same as E1-2100) http://en.wikipedia.org/wiki/List_of...13.2C_28_nm.29

          they could use PCIe -> Usb3 controllers. Yes, you need PCIe lanes for USB3 support! These processors only have 2 spare (after allocating 4 LANES to the 16x slot).

            Lets say if e1-2100 is comparabile with Intel Core Duo 1.8GHz processor then 1080p may play smooth but i think it is not it comparabile with that more like Pentium Dual Core ore something...

            http://helpx.adobe.com/flash-player/...sh-player.html

            720 maybe... but who cares about flash on Linux when even Adobe does not care

              More importantly (to those who design/build it) it ups the TDP. The Kabini/Temash SOC goes down to 3.9 Watts, still with 2x 1.0 GHz cores with the A4-1200 still featuring the same 2/4 USB 2/3 ports. Adding bandwith to the links always adds power draw.

                Talking video playback, all Kabini/Temashs can handle 1080p when the software can utilise UVD3 (hard wired video decoder upto h.264).

                  Maybe, but the NUC is something different. The case is so small you could not even fit a HDD in. The ITX formfactor is just more flexible and has way more USB etc. connectors available. Then for the coming graphics benchmarks I am very curious how the amd hd88210 will compare to the intel hd4000 derived one.

                    Yea, I can't find this for anywhere near $30. It's more like closer to $100.

                      Comparison to NUC is off anyways, if such FF is preferred (which is the case for me), compare it to Zotac's ZBox nano AQ01 (Kabini A4-5000). Zotac where the inventors of the "NUC form factor" anyway, the nano AD10 dates back to 09/2011. First NUC I can find is 11/2012.

                        In a very good deal, the ECS KBN-I/2100 mini-ITX motherboard that features an AMD E1-2100 dual-core "Kabini" APU can be found for just over $30 USD. How though is the performance of this ultra low-cost motherboard + APU combination when it costs less than a Raspberry Pi? Here are some benchmarks and the Linux impressions.

                        Mr Michael, can we have the dmips/mhz/core value for both Kabini and Baytrail. There is really something wrong with those benchmarks.

                          I'd like to know the ASPM support.

                          Seconded.
                          It needs also sensors-detect for infos on Sensors / Super IO chip, ACPI implementation (which compiler used for the tables) etc. etc. All very interesting points for a mainboard.

                            Suprising nobody complained about the size of the ATX power connector. Something really needs to change here. This system is 9W TDP + 2 x 3W DDR sticks + 4 x 2.5W USB2 + 2 x 4.5W USB3 = 34W. The other stuff on the board might use few watts. Guess what size connector ARM boards with 15-20W TDP use? http://goo.gl/CykFEX
                            Why does x86 shit use so big power connectors?

                            Probably because this board could possibly also support 75W TDP PCI express graphics (450W TDP with extra connectors). Who would be that insane? The 25W max GPUs are designed for this sort of systems. That would mean 60W max TDP for the whole system. Well.. at least this doesn't have the extra 4..6 pin ATX power connector. I just complain because the wiring is a mess with all x86 systems, especially these smaller ones.

                            Another thing that is crap with x86 is the sata connector. It's fragile and doesn't provide power. SSD disks barely consume 2W and spinning drives use 2-5W. it would be easy to extend the connectors to fight the wires.

                              Well, cause it is still a standard. Other way round people would have screamed over a different PSU and that it is not compatible. But at least there are Pico-PSUs which are quite neat, besides that they still require a wall voltage -> 12 V external PSU brick, and they are already expensive (plus that you need the very external brick).
                              The problem with current ATX-PSUs is, that these stupid things are hardly sold below a 350 W power level. You can still get these ridiculous PSUs with 1000 W but try to find a 200W one or less. For YEARS my computers have a max. power consumption of about 120-175 W (big box, quad core 3,1 GHz, dedicated GPU) down to something about 10-40 W (E-350, Via C7, Geode LX and so on, okay the Geode has its own PSU). But I am still sitting on these 350 W bricks which was about the lowest I could obtain. At least they still have enough cables for HDDs.

                                Every once in a while (very rare), there are x86 mITX boards with a power connector like you showed for the ARM boards. Last time I saw one, it only had a PCIe x1 slot for the reasons you told. But that's a niche, most mITX boards come with standard ATX P/S socket ande PEG slot even if it's only conected with four lanes.

                                There are SSDs that draw more than five watts on heavy write loads btw.
