OMAP3530 Vs Snapdragon: SURPRISE!!!

[Sergio Lorenzo]

Just take a look at the video and give our oppinion ;-)

Nice fake review. My HTC Desire is smooth on that game.

 

[Sergio Lorenzo]

Are you sure? Maybe the low bat could be the responsible of that difference... more oppinions?

 

[craigcrawford1988]

I'm 100% sure. My milestone even has difficulty swiping through the homescreens without lagging. The Desire does it smooth.

 

[Sergio Lorenzo]

That's true, but it has nothing to see with games. Android default interface and HTC Sense don't use graphic acceleration to be moved. In that case snapdragon is clearly faster... but if we take a look at the OMAP and Snapdragon graphic issue, we can found a TI C674x floating point DSP (520 Mhz) on OMAP34xx and another 6th gen 600 Mhz DSP on Snapdragon with similar specs... with the big diference of comparing TI (texas instruments) DSP's with others... far better in mi oppinion.

I'm sorry? I had lag in both the menu and games on the Milestone. I had lag EVERYWHERE.

Desire = no lag.

I'd like to watch it by myself so... could you make a brief video in same conditions running a 3D game? I'm not saying it's a lie, just curiosity ;-)

PD: you're so lucky having both :-O

I will do, I'll make one in a few days. The desire is MUCH faster.

My droid runs Asphalt 5 better than my Incredible, which is pretty much the same internals(that matter) as the Desire.

It's a known fact that Asphalt 5 is optimized for the PowerVR SGX series GPUs; the AMD in the Snapdragon chipset just doesn't run it as well. The AMD GPU has approximately 1/2 the fillrate of the PowerVR - although it can draw more polygons per second. Unfortunately, with an effects-heavy game such as Asphalt 5; the fill rate is key.

Plus, the 2 GPUs use an entirely different form of texture compression, and from what i've read; the Snapdragon's GPU has to store textures with no compression whatsoever; which eats bandwidth.

If the game is optimized for both GPUs, the playing field will level out.

Were you reading? This is about the Milestone. NOT the droid.

Droid = unlocked
Milestone = locked and underclocked.

Exactly. It's like NVIDIA vs ATI, if one game manufacturer works with NVIDIA and does no optimizations for ATI GPUs then terrible performance will be had for people who bought ATI.

Edit: Big update! I just read the reviews on the Asphalt game page. Many people are complaining it "lags like hell on my HTC Desire/tattoo". I thought the game used in the review was Raging Thunder, I tried that and it was perfect.

It just goes to show if you use something that has been optimised for that particular GPU/CPU, it will perform better. The game is to blame - that is why the review is fake.

But even without optimization for a certain chipset, OMAP DSP is more efficient as I've seen in both datasheets (talking about tech specs, deeper than memory Rash-to-cash or Mhz). The problem on Android not to be running as weel as in desire or NExus one goes further than the simple fact of the processor properties: it's a driver issue, not hardware.

In fact, I have an IGEPv2 board for developers which has an OMAP3530 running 720 Mhz and at the moment is running an ubuntu 10.4 (the only diference: 512 Mb RAM) and rendering HD video 720p fluently.

Update: Uploading my video review to YouTube now. Will be up within an hour or two!

Are you sure about that? Wait until you see my video review and see the WiFi performance difference

I'll see it as fast as you make it ;-)

Unfortunately, I don't have a dev's PCB kit with snapdragon on it... but as it is part of my job... you know what I mean ;-) jiji

Snapdragon is clearly faster but this is not everything (believe me as I know what I'm talking about ;-) ).

Oh I do believe you. When you said it was a driver issue I am 100% with you on that, the hardware is great. I'm just saying for what we have now Snapdragon is a faster chip but needs more Android support to unlock it's potential.
