[Asus  Eee Pad Transformer Prime] BarryH_GEG:
The issue so far with all the Android SoCs is memory bandwidth. In the article Dianne Hackborn wrote that constraint is what's causing graphics challenges in the OS, video, gaming, etc.

Here's a chart from Anand comparing GPU's and his comments on the Teg3 GPU...

Per core performance has improved a bit. NVIDIA worked on timing of critical paths through the GPU's execution units to help it run at higher clock speeds. NVIDIA wouldn't confirm the target clock for Tegra 3's GPU other than to say it was higher than Tegra 2's 300MHz. Peak floating point throughput per core is unchanged (one MAD per clock), but each core should be more efficient thanks to larger caches in the design.

A combination of these improvements as well as newer drivers are what give Tegra 3's GPU its

2x - 3x performance advantage over Tegra 2

despite only a 50% increase in overall execution resources. In pixel shader bound scenarios, there's an effective doubling of execution horsepower so the 2x gains are more believable there. I don't expect many games will be vertex processing bound so the lack of significant improvement there shouldn't be a big issue for Tegra 3.

Here's NordicHardware's take on the Exynos 5250...

Samsung Exynos 5250 in production - Cortex-A15 coming

CPU / Chipset - Published on Friday, 27 January 2012 16:45 Written by Anton Karmehed

Samsung Exynos 5250 will be one of the first system processors sporting ARM's new processor architecture Cortex-A15. Samsung revealed during a conference call today that it has started test manufacturing of the new 32nm chip.

Samsung says the new processor sporting two CPU cores at 2.0GHz will go into mass production in Q2. This means the circuit will find its way onto the market in Q3 or Q4, about the same time as Qualcomm's new Krait architecture and Snapdragon S4 platform.

Samsung will be making Exynos 5250 on its own and decides to stick to 32 nanometer technology, which could give them a headstart on other competing products sporting the Cortex-A15 architecture. Exynos 5250 will with its new architecture and tweaked frequencies be twice as powerful as the current Exynos 4210 at 1.5 GHz and the integrated graphics core will be 4 times faster says Samsung. The circuit will sport 12.8 GB/s bandwidth and capable of powering displays up to 2560 x 1600 pixel resolution, which should fit well with the next generation tablets.

Exactly which graphics circuit Samsung has decided to use in its system processor was not revealed. It uses Mali-400MP in the current Exynos 4210 and

ARM claims that the next generation Mali-T604 will be up to 5 times faster

, which means it could be Mali-T604 that is found inside the coming chip. Although, Samsung also works with Imagine Technologies that made the PowerVR graphics circuit for Hummingbird. Either way, Samsung Exynos 5250 will have

a much more powerful GPU than the system processors available today

.

Samsung has set the sight on tablets mainly, but we would not be surprised if also smartphones gets to take on the new system processor later this year. Perhaps even the coming flagship Galaxy S III that is rumored to appear at Mobile World Congress next month.

As an analogy, having a car capable of running at 200MPH does you no good if you're using S-rated tires that are good up to 112MPH. So, once again, Nvidia's first with a new generation of SoC and once again behind when it comes to graphics (NEON left out of Teg2). The latter's ironic since that's their core business. This isn't a plug for Samsung, all the next-gen chips still under development are going to have significantly enhanced graphics processing power.

P.S. - Demandarin, I know Wayne will blow the 5250 away. But it's Teg3, not Wayne that's competing against it and the chips that are going to be released mid-year. By the time Wayne's here, the 7250 will be under development and the cycle will start all over again. And this is a discussion specifically about the GPU, not raw HP. Teg3 has that in abundance. Depending on the application, GPU and be more important than CPU. How many water-cooled i7 Extreme gaming desktops have you seen with 512K graphics cards?
