NVIDIA Tegra 4 benchmarked, breaks all sorts of speed records (video)

When NVIDIA unveiled Tegra 4 back at CES, we scrambled to get hands-on with a reference device. And though our initial performance impressions were positive — it runs 1080p video and games smoothly — there was only so much we could say to illustrate how fast the performance is. After all, Tegra 3 already does a fine job handling games and full HD movies. What we really needed were benchmarks, some quantitative data to help show the difference between Tegra 4 devices and whatever’s currently on the market. Fortunately for all of you, we just got our chance: here at Mobile World Congress, the company has reference tablets set up expressly for the purpose of running tests. So, we did just that… over and over and over until we had a long list of scores. Meet us after the break to see how it fared. Filed under: Tablets , Mobile , NVIDIA Comments

NVIDIA officially unveils Tegra 4: offers quad-core Cortex A15, 72 GPU cores, LTE support

One new SoC per year? That’s what NVIDIA pledged back in the fall of 2010 and today at its CES 2013 presser, it delivered with the Tegra 4’s official unveiling. The chip, which retains the same 4-plus-1 arrangement of its predecessor, arrives with a whopping 72 GeForce GPU cores — effectively offering six times the Tegra 3’s visual output and is based on the 28nm process. It also is the first quad-core processor with Cortex A15 cores on-board, and offers compatibility with LTE networks through an optional chip. NVIDIA claims this piece of silicon is the world’s fastest mobile processor, and showed a demonstration in which a Tegra 4 went head-to-head against a Nexus 10 in loading websites (you can guess which one won). The Tegra 4 also introduces new computational photography architecture, which adds a new engine to drive the image processing and significantly improve the amount of time it takes to calculate the necessary mathematics 10 times faster than current platforms. To show off its power, NVIDIA demonstrated HDR rendering on live video. The chip is also capable of implementing HDR in burst shots and with LED flash. The idea, NVIDIA says, is to eventually make our mobile cameras more powerful than DSLRs, and this is certainly a step in the right direction.

NVIDIA Tegra 4 processor details leaked: 4-plus-1 cores, 28nm, six times the power of Tegra 3

NVIDIA’s next superhero-themed mobile chipset has possibly made an early appearance in a leaked side in China, and it looks like it wants to go toe-to-toe with the latest processors from Samsung and Qualcomm. The Tegra 4 (codenamed Wayne) will apparently offer the same power-efficient 28nm process found on its Snapdragon rival and according to the slide from Chip Hell , there’s a dizzying 72-core graphics setup. That’s apparently 20 times the power found the Tegra 2 and six times that in the last-generation Tegra 3, which powered, among other devices, the Nexus 7 . Those graphics cores will be able to power screens up to 2,560 x 1600, with 1080p output at 120Hz, while the leak also mentions 4K — if only in passing. We won’t see any increase in CPU cores this time, with the same 4-plus-1 setup , but we are likely seeing a move to ARM’s latest design, the Cortex-A15 . It’ll also catch up with USB 3.0, being NVIDIA’s first mobile chip to do so, alongside dual-channel DDR3L memory. We’ve reached out to chipmaker and we’ll let you know when we hear more, but it’s highly likely we’ll be seeing this next-generation processor early next year — say, at a mobile trade show .
