Apple And it was that time of the year again - Apple held one of its product announcements. This one focussed on the iPad mostly, and while some will call it a disappointment merely because virtually everything had already been leaked, I'm still in awe over the fact the newly announced iPad has a 2048x1536 display. My mind is blown.

Quick, can you name a devite with single core gpu?


Every single ARM-based cell phone, except those using an MP2/MP4 variant of a PowerVR GPU. The Qualcomm Adreno series are single-core. The TI OMAP CPUs use single-core GPUs. The current-gen ARM-Mali GPUs are single-core (there are multi-core variants of the T-series of Mali GPUs coming down the pipe).

You need to stop thinking in terms of the PC architecture. Everything is different when it comes to ARM.

A GPU "core" is literally an entire GPU. Thus, an SoC with a "multi-core" GPU physically has multiple complete GPUs inside.

Or dual core GPU?


The Apple iPhone 4S and the Apple iPad2 (both using the A5 SoC) have dual-core GPUs, the PowerVR SGX543MP2 (the MP2 part means it has 2 complete copies of the SGX543 GPU onboard).

How many GPU cores does a random ATI radeon have?


Most only have 1. There are a couple of super high-end cards that have 2 complete GPUs on the PCB, configured with CrossFire internally to act as a single GPU. "Stream processors", "shaders", etc are not "cores". There's only 1 GPU core in a standard Radeon GPU. Same with nVidia GPUs.

Or Galaxy S 2?


1 GPU, thus only 1 GPU core.
