It is the day after the NVIDIA keynote and the Tegra 4 floodgates are open. Sure, the rumors were fairly accurate, but I guess speculation waits for a solid basis to be believable.
The Tegra 4 marries 72 of the expected GPU cores with four… “plus one” as the bonus core is present although 4+1 branding does not seem to be… ARM Cortex-A15 cores. This push to an A15-based design provides a significant performance increase over Tegra 3. Another interesting feature is the ability to transmit 4K video should you have a suitable source or the rendered application can support 4K at a suitable framerate. You can then add in Icera’s LTE modem which is interesting in its own right to see a compelling product.
Jen-Hsun spent about as much time justifying the need for speed as he did hyping its performance. Photographers, particularly those who wish to dabble with HDR, are able to use the Tegra 4 to vastly increase the speed of image processing at the time of taking the shot. Tonal mapping for an HDR image will take just 200ms of processing which allows HDR to be used along with burst mode and a flash.
Paul Thurrott over at the Supersite for Windows ponders whether this was Microsoft’s vision for Windows RT. He wonders whether Microsoft will try to take a mulligan on the first generation similar to Windows Phone 7-based devices led us to Windows Phone 8. At the same point, the weight which the Surface was designed to bare is pretty immense if it was just designed to buckle to Tegra 4. I would not put it past Microsoft although the Surface does not strike me as a product designed to have a doughy half-baked middle -- despite what actually shipped.
PC World also notes how Qualcomm continues to improve their products and have just recently transitioned to a 28nm process for the Snapdragon S4. Qualcomm is a giant and even then there is also Samsung to contend with in the ARM space -- then you consider x86 brings at least Intel to the game with its massive advantage in legacy software that are usually not abstracted by a platform-independent runtime layer.
