Nvidia has been golf stroke out ARM-based platforms for many years now, but has nevertheless to really leverage its graphical experience on mobile platforms. The GeForce ultra-low voltage (ULV) GPUs prepacked with the company’s Tegra chips have been regarding on-par with the Adreno and PowerVR, but that would change with the discharge of Nvidia’s next ARM chip. At a current event, Nvidia had a newly optimized demo of the Tegra 5 chip (codenamed Logan) which can feature a Kepler-based GPU kind of like the cores in desktop GTX 600 and 700 cards.
This isn’t the first time logan semiconducting material has been shown to the general public — that was back in Gregorian calendar month, but the development board and demo have been any refined since then. The dev kit for logan is still quite large, but the system-on-a-chip (SoC) itself are smaller than a dime when it\'s complete and ready for use in phones and tablets. Even while not stepping the design down a notch –Tegra 5 can still be 28nm — the GPU in logan looks to be capable of some spectacular feats.
Nvidia talked about a few numbers at the event, but the centerpiece of Logan’s beginning party was the Faceworks “Digital Ira” rendering check, which Nvidia has been working on for many years. this can be an advanced period engine that renders a sensible external body part with proper images, lighting, skin textures, and languages that almost reach vaulting the uncanny depression. we have a tendency to last saw Ira on logan over the straw-hat, but the locomotive had been climbed down for the debut — the skin shaders area unit simplified and also the scene is simply being drawn at 1080p.
In a tablet, Nvidia believes the beefier 2W version of logan are more powerful than the PS3 or the GeForce 8800 GTX — within the neighborhood of four hundred GFLOPS. Granted, these area unit both many years out of date, but we’re undoubtedly into the realm of desktop-level graphics. These raw numbers place the mobile astronomer GPU at around 5.2x the ability of the PowerVR SGX 554MP4 within the most recent iPad. At this level there\'s the potential for memory bandwidth to bottleneck performance, but the company has not nevertheless commented on this.
