How is the TP2 faster that the TP?

[HeXeD]

Regarding the processor being older, I got this off of ppcgeeks a while ago but I forgot what thread and who I took it from:

""As to the processors, what we got is:

7200 (TyTN II, Touch Cruise, etc)
7200A (Daimond 2, TP 2, X1)
7201 (this one does not actually exist, I think)
7201A (Diamond, TP, HD)

Now, AFAIK the only difference between the 0 and 1 variants is the Broadcom patent that has been worked around. Apparently this did degrade performance in certain specific areas, which is why the 0 variant has preference over the 1 variant, and the Broadcom vs Qualcomm fight has since ceased, so the 0 variant can be used again.

The A variants vs the non-A variants is the die-size. The A variants are 65nm and go to 528mhz, the non-A variants are 90nm and go to 400mhz.

7201A was produced before 7200A. So in fact, the TP2 has both the better and newer processor compared to TP "

That applies to just the gsm version of the tp2. The telus, sprint and verizon has both cdma/gsm and these versions use the older 7600 processor.

Can you provide a source to that? I find many sites saying the opposite:

Edit: AHH.. found this link...

Yayy, glad you found it. I was about to post the exact same link. Even the gsm version of the tp1 has a different processor than the cdma version. I think the gsm version has the 7201A like you mentioned but the cdma version with telus, sprint and alltel where running 7501A's and verizon was running a different one from everyone else.

I'm glad you started this post because I've been thinking the same thing.

"How do you take the same (or lesser) processor and specs, and power a screen that's larger, and get better performance!?!?"

I admit I haven't actually used a TP2 myself, but as an embedded software developer, I know that "if the TP2 is same basic specs, and it runs faster, that means the TP could ran as faster...or faster".

I'm intruiged by everyone's review of the performance and speed.... and I'm sure it is speedier, but there's an explination somewhere that means either there's a graphic accelerator in the TP2, or there's some fundamental software flaw of TP that could be corrected.... (tho i'm running EnergyRom and lovin it..no complaints here... I just want the larger screen and better keyboard)

Yeah, seriously. If someone could find out what exactly is to 'blame' for the *much* better performance of the TP2 in comparison to the TP, I'd love to know too.

All I know is that I've used both... heavily. And none of the custom ROMs I loaded on my TP ever performed as well as the TP2's stock Telus ROM... not even close. Which leads me to think that it *might* be a hardware difference of some sort... although it seems pretty well-documented that this isn't the case.

I am no hardware or software developer but I am sure that there is alot of optimization going on in the software that makes it easier for the hardware to process. For example, when the ps3/xbox360 first came out, the graphical capabilities of both systems were pretty good, but over the years programers have learned to optimize the software so now you have games that look so much better and runs so much faster using the same spec hardware from a few years ago.

While what you say is true, there is a big reason why such a thing isn't nearly as easy on a device like our phones - The chip-level hardware specifications are (usually) widely known for gaming consoles, and those consoles usually have optimized drivers for all hardware as soon as they're released, since they are intended to serve as multimedia machines. HTC (and Qualcomm) are not all all forthcoming with the needed level of technical detail to allow programmers to write software to directly address the hardware to bypass the lack of drivers. For example, just finding the datasheet for most MSM-series processors (such as the one in the Mogul/VX6800, since it's fresh in my mind) isn't possible - Qualcomm intentionally removed them from public access, to prevent people from being able to write their software to account for the lack of a 2D or 3D driver. In essence, since HTC (and probably other manufacturers) didn't want to pay to play with their toys, Qualcomm got huffy and hoarded their toys.

For this reason, I will be far more likely to make my next-generation handset a Tegra-based (Nvidia) system, before I would consider a Snapdragon (Qualcomm) system.

Maybe my example should have been better but all I was saying is given enough experience these developers have learned a few tricks here or there to optimize things so it can run smoother regardless of the lack of support from qualcomm. Of course every operation wont be perfect but its atleast a little better compared to the previous model(tp1)

Well if the same rom is ported over to the original TP and it is nowhere to be found it may be other aspects, lets list a few: (I will use references to it as a computer)

1) Faster RAM or maybe a better motherboard. (just like if your mb speed is at 800mhz, it may support 1066mhz ram but it will run at only 800mhz)

2) Downscaling, aka it is possible that the TP resolution is non-standard and it has to downscale from a higher resolution.

3) The TP2 by reports shows that it has smaller battery life despite a bigger battery, even in standby...screen size aside, if the screen is off it shouldn't effect it to that extent, which may mean that maybe the performance is linked with the battery life.

This is all speculation though
