Ok, then. Can you then explain why there are several examples of the ARM11 based N97 (non-accelerated) loading web-pages faster than the ARM11 based accelerated iPhone 3G?
In what way is it "accelerated"? The GPU? The GPU does not impact the website loading/rendering speeds.
How variable are these load times? Are we talking a few percentage difference or the huge 100%+ difference between the iPhone 3G and 3GS.
Can you please show me the tests?
I live in and around a major UK city. And I get good 3G coverage, though not 3.5G. Downloads average around 100kb/s on a good day.At busy times, or when travelling more than 10 miles from the city centre, I'm often staring at EDGE if I'm lucky.
3GPP Rel 99? Really? Is your carrier still in the dark ages? It is called Release 99 for a reason... it was meant for the last century! 😊
If you don't mind me asking, which city? If you're not comfortable answering that, at least give us an indication of how big population wise. What network are you on? O2? Three?
I find it unusual that a large UK city does not have decent HSPA coverage. While I was travelling around the UK for work (and fun), I certainly did not run into any problems accessing the net using my prepaid Vodafone SIM in major centres (London, Manchester, Leeds, Birmingham, Edinburgh, etc).
The only times I remember having problems accessing the net (via 3G) is in regional towns or on the highways between towns. Actually I don't even remember running into any problems while I had a long stay in Harrogate which certainly isn't a big town.
Stuck in Somerset at my parents house (only 5 miles from a major town, no hills in the way), I get three bars of GSM and GPRS only for data. What use a 1GHz processor then???
The 1 GHz processor will allow you to use far richer applications *cough* games *cough* to pass your time because you don't have decent access to the net.

The above test were done on a WiFi connection and goes to show how a simple CPU / RAM interpretation will get you nowhere.
The comparison made in that article has so many uncontrolled variables (and not to mention that they're all ARM11 SoCs) it doesn't tell you much. You have different OS builds, different browser, and even different screen resolutions.
The beauty about the iPhone 3G vs iPhone 3GS comparison is that the only difference is the SoC, a 400MHz ARM11 vs a 600 MHz Cortex-A8. They are both running the same build of iOS 3.0 and the same Mobile Safari 3.0 browser.
Browser speed can apply to more than one thing. At its simplest its about how long it takes a page to appear. However in real world usage that's not the only factor. Speed moving around the screen, speed of the UI, responsiveness, stability etc.
I don't dispute that and yes I think UI responsiveness (zooming, scrolling) is important but I think loading/rendering speeds is just as important, especially if you're constantly browsing complex sites like Engadget.
In practise I would still expect data speed to the limiting factor most of the time.
I think we'll have to agree to disagree here then. We'll just have to wait for Nokia to release a Symbian^3 device with a Cortex-A8 SoC. The comparison won't be as good as the iPhone 3G vs 3GS comparison (as they'll probably be running different OS and browser builds) but I bet that browsing speeds will get a significant boost nonetheless.
In terms of way the N8 will be better than previous Nokia devices (e.g. N97) for browsing.
- Symbian^3 - NGA and new networking architecture.
- GPU - important more because of its absence previously.
- Capacitive screen - better for moving round the page (in my opinion on the relatively few areas where capacitive has a clear advantage).
These 3 points will improve the useability of the browser after the page has loaded. Unless the network stack on Symbian^1 is horrendously broken, I wouldn't expect this to make a difference to browsing speeds.
- CPU and RAM - but in most cases this is not a limiting factor.
Going from a 400 MHz ARM11 to a 600 MHz ARM11 is definitely going to make a difference.
All of these factors will likely be over shadowed by the new browser (i.e. it will offer the biggest performance improvements).
The new HTML and Javascript rendering engine should improve speeds but isolating how much each factor makes to the browsing speed will be impossible.
People are equating the N8 architecture with the older generation of the ARM 11 chips... clearly they are in the same family, but they do not have the same capabilities. There's a good reason the N8 can encode / decode HD video - something the earlier phones can't do. The N8's processor is significantly more powerful than the previous generation of Nokia devices (N97, 5800, E72 etc etc).
The N8 may have upgraded co-processors to do video HD encoding/decoding but the general purpose CPU, the unit responsible for doing webpage rendering is still the same ARM11 CPU in the N97. The clock speed is faster but architecturally, the general purpose CPUs are identical.
If browsing websites on a PC is slow, you don't upgrade to GPU to speed things up. You upgrade the CPU.
