After covering a number of other NVIDIA innovations over the past year, NVIDIA unveiled its latest mobile chip. Not Tegra 5 -- NVIDIA appears to be dropping the five altogether -- but Tegra K1 (codenamed Logan).
Tegra K1 chip is that it offers the same programming capabilities as the conventional NVIDIA GK104 GPU. The Unreal 4 engine will be coming to mobile as a result, which makes sense, given the new core's capability. What's more impressive, however, is that the new mobile chip will comprise 192 Kepler CUDA cores, which is over a 2.5X increase from the current generation Tegra 4 SoC.
NVIDIA ran through a number of mobile demos highlighting just how powerful the new core is, with the usual demonstration of impressive capabilities and lighting environments. Not that we're downplaying the performance or visual fidelity of Tegra K1 -- the new chip looks incredible -- but we've seen some of these demos from NVIDIA already, when it debuted Logan earlier this year.
The big news of the evening from NVIDIA was that we'd soon see two SKUs for Tegra K1 -- a quad-core Cortex-A15 32-bit chip at 2.3GHz, or a dual-core Denver at up to 2.5GHz and a whopping seven-way superscalar architecture. That's frankly enormous -- it means that Denver can execute up to seven instructions simultaneously. The "up to," however, is extremely important -- we don't know what kind of decode resources the Denver CPU has, which means we don't know how easily it can hit that execution capability.
NV was mum on a ship date for either architecture but indicated that the Denver-based chip had only just gotten back from the foundry in a useable form. So it's safe to say we won't see Denver shipping in products until the back half of the year, given the typical ramp time. The 192-core Kepler-based Tegra K1 with standard Cortex-A15 cores should be ready to ramp well before that.
It'll be exciting to see just how much performance NVIDIA can squeeze out of its new architectures -- this could be the GPU that reignites that company's flagging mobile business and brings PC-level gaming to mobile architectures at the same time.
