NVIDIA: Qualcomm Snapdragon S4 Pro performance claims are wrong

The Inquirer reports NVIDIA attacked Qualcomm over claims that the dual-core Snapdragon S4 Pro beats NVIDIA's quad-core Tegra 3 SoC. Seems like the start of a good old fashioned mud fight, this time not in the discrete graphics card market but in the mobile chip market.

Yesterday Qualcomm's Rob Chandok, SVP of Software Strategy and president of the firm's Innovation Center told journalists at a roundtable that its Snapdragon S4 MSM8960 system-on-chip (SoC) and its newly announced dual-core Snapdragon S4 Pro beat Nvidia's five-core Tegra 3 chip in just about every benchmark under the sun. Now Nvidia has fired back, saying that the figures bandied about by Qualcomm are incorrect based on reviews on the web.

Chandok did not mention Nvidia's Tegra 3 by name in his presentation, instead using phrases such as "quad-core 1.3-1.4GHz chip", which anyone with access to a search engine can work out is a reference to Nvidia's Tegra 3 chip. Nvidia clearly thought Chandok's comments were aimed at its burgeoning Tegra 3 chip and fired back claiming the results simply do not correlate with independent reviews.

Ubuntu 11.10 vs. Mac OS X 10.7.2 Performance @ Phoronix

Phoronix compares the performance of Ubuntu 11.10 and Mac OS X 10.7.2, you can check it out over here.

After delivering benchmarks last week that were comparing the Intel Sandy Bridge performance of Mac OS X 10.7 "Lion" vs. Ubuntu 11.10 "Oneiric Ocelot" when it came to the Sandy Bridge OpenGL graphics performance, here's a comparative look at the performance of Ubuntu 11.10 against Mac OS X 10.7.2 from the Intel Sandy Bridge-based Mac.

AMD Bulldozer hotfix provides just limited performance boost

TechPowerUp reports the new hotfixes from Microsoft for AMD's Bulldozer processor provide only limited performance boosts in a small number of applications:

The reviewer put FX-8150 through synthetic tests such as AIDA64 (CPU benchmarks, FPU benchmarks), Cinebench 11.5, MaxxPi (multi-threaded PI calculations), WPrime, Twofish AES, 3DMark (Vantage and 11), ComputeMark; and some real-world tests such as WinRAR, Resident Evil 5, and Battleforge. Barring Resident Evil 5, where the patched FX-8150 produced 4% higher performance and WinRAR, where it produced 3% higher performance, there were no significant performance gains noticed.

Intel Sandy Bridge VA-API Video Acceleration Performance @ Phoronix

There have been a number of Intel Sandy Bridge articles on Phoronix since the January launch of this next-generation Intel CPU micro-architecture. It's ranged from the Linux support being challenging to dealing with motherboard problems and then the graphics performance being fast relative to previous generations of Intel graphics and for being based upon the classic Mesa driver architecture, but much slower than Windows. Last week then the Sandy Bridge Linux performance became much more interesting after a simple patch led to a huge performance win to the point that the open-source Linux driver performance is much closer to their full-featured Microsoft Windows driver. What is the next chapter in the Intel Sandy Bridge Linux story? A look at the VA-API video acceleration playback performance.
