Nvidia claims better performance than A6X

Written by Peter Scott



Battle of oversized mobile GPUs


Here’s an interesting tidbit from Anand. According to Nvidia's performance projections, as well as some number crunching on Anand’s part, the new Tegra 4 SoC could theoretically outpace Apple’s A6X, albeit with a narrow margin.

Anand reckons Tegra 4 should deliver 74.8 GFLOPS versus Apple’s 71.6 GFLOPS. What’s more, the figures put Nvidia’s new chip ahead of Samsung’s octa-core Exynos 5 (SGX 544MP3, with 51.1 GFLOPS.

Nvidia dismissed earlier Tegra 4 benchmarks leaked last week, saying they were carried out on much older silicon running at very low clocks, way below the final GPU clocks.

So there is a chance Nvidia will be able to retain the graphics performance crown with the Tegra 4, although Qualcomm’s new Krait 400 should drink its milkshake in CPU performance. However, we still don’t know much about Qualcomm’s choice of GPU in 800 and 600-series Snapdragon parts, so there is a chance Tegra 4 will be outpaced once they launch.
