That means memory bandwidth is really high. I suspect RAM in the iPad 2 is running at 1GHz instead of 800MHz. Given the 250MHz bus speed, that might just be true. You can't get that kind of fillrate performance with slow RAM like Tegra 2 and other SoCs.
Given this kind of performance, Apple could put a Retina Display in, enable AA, and it still wouldn't take a hit. This is just too crazy. Makes me wonder how the NGP fares against this.
Maybe. But it's not clear if it'll be underclocked like the PSP to save battery life. Sony is notoriously known for pulling such tricks. Plus it seems like the NGP uses a different chip altogether, so it'll be interesting to see how the iPad 2 and NGP will duke it out. And then we have the iPad 3 and Apple's A6 chip to worry about next year.
@ bahamutspirit I doubt it, Sony are aiming at the console level gaming with the NGP, it will more than likely be built around the 28nm process which coincidentally matches the launch window, late 2011/early 2012 What NGP need the most to come close to near console level games is GPU performance, at 28nm the NGP can easily reach 400Mhz for the SGX543MP4 so that effectively puts it at 4x the raw performance of the iPad 2 Graphics performance. The gap is widen even further by the fact they developed some sort Vram for the GPU presumably 128MB in addition to the 512MB of speedy main ram The CPU is the most likely part to be clocked moderately at 1/1.2Gz to keep things at bay which should be more than enough, plus it been revealed on GDC that it uses ARM NEON engine extension which boosts 2D/3D performance and decoding. So the CPU should easily be over 2x faster. And if you think these clocks are far fetched just take look at the SoCs slated to be released on 28nm, Qualcoms Quad CPU will be running at speed of up to 2.5Ghz and beefed up adreno 3.x.x GPU. TI is slated to release early next year its SoC with Cortex A15 CPUs clocked at 2Ghz And it was just revealed that nVidia Kal-el will be build around 40nm process , not 28nm as initially thought. So even though they are on 40nm they have a quad Cortex a9 at 1.5Ghz and GPU core with 3x/5x the perf of Tegra 2. So at 28nm a full fledged SGX543MP4 is more than likely
