^^^This.^^^Silence wrote:One thing I don't understand why there is so much hostility from the RPI biosphere to alternative boards ? It is not that the creators or suppliers of this board are being disrespectful. They just cater an other niche and even then, since when is competition bad ?
When looking up information about alternative boards sometimes I frequently stumble on this forum with a Google query because most of them has been discussed here also. But the threads are for most parts they are very hostile and "fanboy-ish" (which isn't a correct word, but I'm not a native English speaker so this is the best that I can come up with) to say the least.
I was under the impression that the RPI was about cheap computing devices and inspiring others to do the same. But from one the moment somebody seems to steal RPI thunder it is bad, the boards are getting scrutinized (while sorry the RPI isn't walhalla or perfect either) , etc. Be happy that there alternatives out there which makes it easier to experiment.
I personally find it interesting that there are alternatives out there, especially because for a particularly project I need some more punch then the RPI can deliver.
I assume you're optimizing with compiler flags?liz wrote:We're busy benchmarking at the moment against a bunch of A10 platforms, and while CPU is a bit of a wash, we're still streets ahead on graphics performance..
We don't have a thumbs up smiley, but I agree. There are a lot of other low cost boards out there to tinker with. The Raspberry Pi comes in at such a low price you can tinker and blow them up without worrying about the cost or deploy them in some robotics project as controllers, etc. It's all good.scep wrote:Good luck to them I say - the more people tinkering around with devices like this and learning about computing, electronics etc the better.
As to their forums - remember that this forum only had one member this time last year
As a multimedia device, A10 decodes h264 better (read: more fields per second) than bcm2835. That's its strong point, anyway.liz wrote:(i.e. downright misleading) claims about being x3 as efficient as the Raspberry Pi. Hint: they're not. We're busy benchmarking at the moment against a bunch of A10 platforms, and while CPU is a bit of a wash, we're still streets ahead on graphics performance. I'll have a post about this for the front page when we're done, probably some time next week.

You cannot compare the Mhz directly when comparing different processors, because they get a different amount of work done inside a clock cycle, and the A10 has a more extensive instruction set.Relisys wrote:
R-Pi CPU: 700 Mhz. (OC'd: 800 mhz) (stable)
Gooseberry: 1 Ghz. (OC'd: 1.2 Ghz) (stable)
700 Mhz x3=2.1 Ghz
How does the gooseberry havee three times as much processing power?
Pi + power supply + flash + tax = $ 64.13 at RS excluding shipping.I'd rather fork out 35$ for a replacement then 62$.
Not a valid comparison - we are talking replacement cost - the replacement cost for a Raspi is $35+tax+postage since you already have the power supply and other HW.Max wrote:I'd rather fork out 35$ for a replacement then 62$.
So same price category.
I couldn't agree more. "Those other guys are garbage" translates to "We're no better, except at manipulating stats." Still, as consumers (of politics and hardware) I guess that we get the benchmarks that we deserve.abishur wrote:I tend to not care if there's another cheap, low powered board. Indeed, I'm quite supportive of those things. I *am*, however, perturbed by how they're presenting the board. Almost every page makes some dig at the Pi or the RPF and it seems like most the digs are really absurd! And that sort of stuff just isn't my cup of tea regardless of whether if a PC v Mac commercial or a politician. If the only way you can promote yourself is by attack the other guy... well frankly that says to me that you have no worthy substance of your own to stand on.
If we would assume 1.4x per Mhz, and a 1.5x higher Mhz (1,2 Ghz vs 800 mhz, both are single core), that would give 1.4 * 1.5 = 2.1xjamesh wrote: Also, the A10 instruction set *is* more effective at the same Mhz, but not 3x more effective. About 1.3-1.5x I believe would be a more accurate figure.
Fair enough.jamesh wrote: Not a valid comparison - we are talking replacement cost - the replacement cost for a Raspi is $35+tax+postage since you already have the power supply and other HW.
I agree - it is a significant improvement, just not as significant as some imply (I'm not saying the gooseberry people say it - I don't know).Max wrote:
Is indeed lower than 3x for performance (at least on CPU alone, not sure what the RAM does), but still significant.
