Samsung is taking legal action against Nvidia for producing false benchmark results for advertising. The South Korean tech giant claims that Nvidia is confusing the customers by stating that their Tegra K1 processor present inside the Shield Tablet is superior to Samsung's Exynos 5433 chipset which fires up the Galaxy Note 4.

According to Engadget, Samsung claims that regular benchmarks do not show that Tegra K1 delivers better performance than the Exynos 5433 chip. Samsung is not happy about the fact that Tegra K1 CPU from Nvidia is the fastest processor in the world. According to the lawsuit filed by Samsung, six patents have been violated by Nvidia whereas two have been violated by an Nvidia client called Velocity Micro.

When Samsung accused Nvidia for false benchmark results, the latter clarified by saying that the benchmark tests were conducted on the out-of-the-box versions of Note 4 and Shield Tablet. According to GSMArena, few months ago Nvidia had accused Samsung and Qualcomm for violating its own patents. Phandroid states that Android OS on the Galaxy Note 4 is overlaid with TouchWiz skin and the Shield Tablet comes with unmodified Android user interface, this difference can make the Shield Tablet to churn out better performance.

Nvidia wants the ITC body to stop the shipments of all the Galaxy devices such as the Galaxy Note Edge, Galaxy Note 4, Galaxy S5 and Galaxy S4 that are powered with graphics chipsets from Qualcomm Adreno, ARM Mali and Imagination PowerVR. Nvidia claims that Samsung has been using their patented GPU without acquiring a license. Nvidia also states that these graphics chipsets have violated seven patents. Interesting thing to note is that in its history of 21 years, Nvidia is for the first time filing a patent lawsuit.

GSMArena further states that Nvidia was not surprised when Samsung counter attacked on them with a lawsuit for false benchmark results. Nvidia says that the initial patent violation case that it has filed against the South Korean tech giant is a very serious issue compared to the recent lawsuit filed by Samsung against Nvidia.
