What makes you say that the Galaxy is better? I'm being completely serious. Because I'm starting to lean towards getting one myself even though I don't like keyboards, but from what I hear, it's processor is better/faster with the hummingbird, plus I think I read that is has an actual GPU which makes it better for games.
OK.
The EVO's processor is a Qualcomm Snapdragon 8650.
Snapdragon 8650=Scorpion Core plus (AMD Z430 GPU plus 600 MHz DSP core (floating point, if I'm not mistaken))
The Galaxy S Pro uses the Samsung S5PC110 (Hummingbird) processor. Its GPU is a PowerVR SGX540.
That's way above the Droid X's OMAP 3630 (SGX530) or EVO Snapdragon 8650.
For gaming, you may be interested in a GPU 3D rendering spec called "millions of triangles per second" - I'll call them Mtps.
Here's a rundown of some various phone's spec for that:
The Snapdragon 8650 is rated at 22 Mtps.
The Palm Pre with a PowerVR SGX 530 is rated at 14 Mtps.
The iPhone 3GS with a PowerVR SGX 535 is rated at 28 Mtps.
The Samsung Galaxy S processor is said to do a whopping 80 to 90 Mtps (like a Snapdragon 8672 in that regard).
I'm not a gamer - but if you're a serious one, then yes, the Galaxy S Pro should be expected to completely trounce an EVO.
The semiconductor-process technology in the Samsung, being a generation later than that in the EVO, along with the AMOLED screen, gives us the expectation of better battery life.
By the way:
I am really hating the endless Android pundits running websites and publishing fluff articles making life difficult for people like you.
Now they have people believing that only certain phones have GPUs - yes, that's true. ALL of the top-line smartphones have them. Every one.
And - these are not industrial workstations, they're mobile devices, so forget what industry pundits are selling with the "separate GPU" rap. The CPU, GPU, DSP module and more are integrated into a single package called SoC - "system on a chip" - on these phones.
