wats the difference between Omap, Xscale, and Samsung processors?

[Guest mikeeey]

ive heard that a IT Omap 200mhz is almost the same as a Xscale 400mhz. is this true?

ive heard that the Xscale one is better, and ive also heard that the Omap one is better.

which is better?

and how high can 400mhz Xscale processors be overclocked to?

also which is better overclocked?

It's my understanding that the Omap processors are designed to process phone and application processes at the same time (double threaded or something like that). But that it can't dedicate both threads to a single task. So they may be effective at doing something without bogging down the phone functions they are still just 200mhz processors when it comes to applications.

Intels (and Samsung mobile procs, I'm assuming) are faster but they're "single" threaded. So if you're doing something processor intensive and the phone rings if that intensive process keeps going the call may suffer.

But I haven't really looked at this personally so this could all be very, very wrong. I'm just going by what I've read at various forums and in reviews and blogs.

Not true.

OMAP 200Mhz is almost the same as XScale 200Mhz. They share the same ARM core architecture.

OMAP have integrated celullar modem on chip die, therefore providing energy saving due to eliminated need of separate wireless chipset.

OMAP is more energy efficient, even comparing to similarly-clocked (200Mhz) XScale.

But XScale can be clocked faster.

Also XScale have Wireless MMX instructions, they give more then 2x times boost in graphics, multimedia and video decoding applications. OMAP has no such.

and how high can 400mhz Xscale processors be overclocked to?

The latest (Bulverde) XScale actually have standard clock of 600+ MHz. Some device manufacturers decide that such high speed is not needed, and run them on 400+ by default, but chip is still the same and can be safely brought to 600+ - and this is not an even considered overclocking yet.

They overclock to 700+ Mhz, though the need of that is dubious, considering high energy usage at such big speeds, already high non-overclocked frequency and Wireless MMX - you can play usual PC DIVX video on 400 MHz XScale at almost 150% speed already (in TCPMP with Wireless MMX enabled).

wow thankyou for the info. i didnt know this. Xscale is definatly wat i want! i cant even imagine how great games, emulators, and ports for games would be.

im sure u can see why im so excited about an Xscale processor judging by my avator picture.

thanks again! :)

Is that HTC Hermes on your avatar? If so, take note that it have Samsung processor, not Intel XScale. There are no modern HTC-made devices that use Intel XScale inside - they use OMAP for EDGE platforms and Samsung for 3G platforms.

Samsung processors don't have Wireless MMX (unique to Intel), and also Samsungs are slightly lower in benchmarks comparing to similarly clocked XScales. Also maximum standard frequency for latest Samsungs is only 400Mhz, therefore they overclock much lower then XScale too.

yes it is, but im getting the 8525, the cingular version. ive seen it say samsung and Xscale. so wich is it?

and if it is samsung, how high can it be overclocked? and wat overclocking program works with the hermes? does XCPUScalar?

EDIT* so yes ive found out the 8525 can be overclocked and i know of a program now. now my only question is, how high can it be overclocked withought starting a fire lol :). jk. but what's the safe overclocking limit, and what's the max?

and how do samsung processors compare to Omap and Xscale as far as multimedia, games, and clocking limit.

It's a samsung. Sorry but I don't know how high it can safely overclocked (if at all).

Samsung is basically cheapened down & simplier version of XScale, and falls somewhere inbetween OMAP and XScale.

It costs less then XScale. Comparing to OMAP it clocks higher, but it lacks built in wireless core, so its not very good in terms of battery drain. Also its performance in ordinary applications is slightly lower then XScale with similar frequency (but not much, its matter of percents and in most cases non-noticeable).

Maximum rated frequency for Samsungs is 400 MHz. It does not overclocks good, its about 10% mostly (but of course you can get lucky, as well as unlucky there).

Also, no Wireless MMX instructions in Samsung. Therefore it does not performs spectacularly in multimedia, video decoding and similar apps.

ah shoot. so it can only be overclocked to about 440mhz ur sayin?

Omap processors (or my sda atleast) can be overclocked about 32% if u count ur default clock at 180mhz. 25% if u count the default as 25%. maybe il start a new topic in the hermes section asking for peoples results who have overclocked their hermes

[Guest Ingvarr]

This is average value.

Maximum is pretty pointless, if can be very high, but your odds of getting such lucky processor will be very low. In any case, overclocking drastically reduces battery life, and battery life of HTC 3G platforms is not good to start with.

yea, which is why i wouldnt constantly have it overcocked, only for short perods of time or when its charging.
