Guest utp_ Posted May 17, 2007 Report Share Posted May 17, 2007 Am confused......which chip powers the i600...? It is 100% 220MHz! Link to comment Share on other sites More sharing options...
Guest ivonovi Posted May 17, 2007 Report Share Posted May 17, 2007 Thanks guys...some websites list it as the Intel PXA272..anyway your responses has cleared things... Link to comment Share on other sites More sharing options...
Guest Sgt_Strider Posted June 8, 2007 Report Share Posted June 8, 2007 Thanks guys...some websites list it as the Intel PXA272..anyway your responses has cleared things... Yea, I notice that too. I don't get why different specs are posted on the internet. Link to comment Share on other sites More sharing options...
Guest orcinus Posted June 8, 2007 Report Share Posted June 8, 2007 Yea, I notice that too. I don't get why different specs are posted on the internet. Because the original rumours, before the i600 was released, stated it uses a PXA272. Also, i think there were shots / a review of a prototype unit, floating about some time ago, showing it as having an XScale instead of an OMAP (but that just may be a false memory).

Guest dijital Posted June 9, 2007 Report Share Posted June 9, 2007 just to make things even more confusing, i got an email from www.samsungmobile.com telling me that the i600 had a 200mhx pxa27x xscale processor in it! wierd! it seems all the reviews that stated a 416mhz processor had a pre production model, i wish this came out as it was VERY fast for a smartphone (25% faster than the samsung i320 that has a 416 xscale in it) Link to comment Share on other sites More sharing options...
Guest orcinus Posted June 9, 2007 Report Share Posted June 9, 2007 The reason OMAP was chosen instead of XScale was probably battery life. Anyway, i find it has plenty of speed for what i use it for (i don't play videos on it, as i find the concept ridiculous, i don't play any games, nor use any GPS mapping software - the last mostly because i can't seem to find any that works properly on i600) and i'm glad a less power-hungry CPU was used, considering the battery capacity.

Guest mixworx Posted June 17, 2007 Report Share Posted June 17, 2007 (edited) Texas Instruments OMAP is OK :-) http://focus.ti.com/general/docs/wtbu/wtbu.../data/omap_1710 Samsung even makes its own ARM-based processors, which are used in some HTC phones too and as I have heard (so not tested), they are slower than 200MHz OMAP even running at 300MHz ... TI OMAPs are designed directly for mobile phones, so highly integrated, almost singlechip solutions (ARM9 core CPU, TI DSP for radio baseband and phone audio processing, ...). Overall performance of phone depends not only on main CPU processing power (even this is very important for some kind of appls), but with quite high screen resolutions and colors depth, graphics processing is important and it seems that OMAP integrated solution is faster here. Another CPU intensive thing is sound processing and I am QUITE SURE that SGH-i600 has hardware chip which helps a lot at least with MIDI ringtones. There are MMF files which is Yamaha/SMAF format and this can be directly interpreted by Yamaha MA-x FM/PCM synthesizer chip. It is simply small Yamaha DX-21 synthesizer from 80s with some extensions and this chip can play VERY NICE arranges stored in MMF like score/notes (metallic bright FM synthesis sounds) with additional PCM encoded sounds (drums, percussions). Such HW synth chips are still fully programmable as any big synthesizer and they can produce many polyphonic and effected tracks with near to CD! quality output without any CPU cycle !!!. Almost every ASIA phone has this Yamaha device inside, many other world-brand phones have software MIDI synthesizer which draws lot of processing power... SMAF IS GREAT !!! ... look at http://smaf-yamaha.com, and as I like very much synthesized music, particulary interresting is Dave Bristow (pioneer of FM synthesized sounds programming and father of legendary DX-7 synth and more follow-ups) role here http://smaf-yamaha.com/develop/dave_tips.html :-). Of course that realtime WindowsCE base kernel runs lot of concurrent tasks (which use lot of threads) and everything depends on proper asynchronous calls to other phone subsystems too (RIL radio DSP and so on...).

Guest orcinus Posted June 18, 2007 Report Share Posted June 18, 2007 That's... odd... I've heard the exact opposite - that Samsung's ARM's are faster then the equivalent OMAP, while having a similar power consumption (or as fast as OMAP with lower power consumption). This, of course, is also second hand, unconfirmed info, however, from what experience i've had with HTC's devices with Samsung CPU's, i definitely wouldn't say they are sluggish or slower than an XScale or OMAP (purely subjective impression, though).

Guest mixworx Posted June 22, 2007 Report Share Posted June 22, 2007 in my experience the samsung cpu easily beats both xscale and omap cpu's in power per mhz. hmm, may be that ARM core itsel is (i dont know) faster, but total available power with optimized drivers may be better with some operations delegated to embedded DSP core (as TI OMAP has). Samsung has no DSP core and XScale currently used hasnt it too. IMHO, XScale (currently Marwell, not INTEL :-) ARM processing is superior against all others implementations (from outside view, it interprets ARM instructions, but it is important HOW advanced is internal implementation of chip). TI OMAP WindowsMobile solutions are very responsive at 200MHz compared to similary clocked others - this is fac tproven by real experiences of mobile phone and PDA testers which I know... :-) Link to comment Share on other sites More sharing options...
