Nvidia Tegra 4 Benchmark Results 42
adeelarshad82 writes "Needless to say, the march of processor speeds always continues. However, Nvidia Tegra 4's benchmark results are off the charts. Comparing the results against several other phones, it was evident that Tegra 4 will make for the fastest mobile phones yet. For instance when benchmarked against iPhone 5, results showed 1640 on Geekbench and 27 fps on GLBenchmark's Egypt HD offscreen benchmark. Whereas the Tegra 4 scores 4148 on Geekbench and 57 fps on the Egypt HD. Of course, the competition isn't standing still, either. Qualcomm is countering the Tegra 4 with its Snapdragon 800, which the company claims is even faster than the Tegra 4. And at the same time Samsung is readying the Exynos 5 Octa."
Cortex A15 processors in the Samsung Chromebook (Score:5, Informative)
Could these recent mobile phone processors be adapted to the desktop?
You can find Cortex A15 processors in the Samsung Chromebook. According to anandtech ( http://www.anandtech.com/show/6422/samsung-chromebook-xe303-review-testing-arms-cortex-a15/6 [anandtech.com] ):
"The Cortex A15 is fast. Across the board we're seeing a 40 - 65% increase in performance over a dual-core Atom. Although it's not clear how performance will be impacted as companies work to stick Cortex A15 based SoCs in smartphones with tighter power/thermal budgets, in notebooks (and perhaps even tablets) the Cortex A15 looks capable of delivering a good 1 - 2 generation boost over Intel's original Atom core.
The IE10 browser tests tend to agree with our JavaScript performance tests, although the CSS Maze Solver benchmark shows a huge advantage for ARM over Intel's Atom here."

There are 2 different "Tegra4" chips. The Tegra4i is the only one that will ever end up in your smartphone, and it only includes Cortex A9 derived CPU cores and a GPU that, while quite good, includes far few processing units than the big-brother Tegra 4.
So basically: Of course the full-blown Tegra 4 beats smartphone chips. Guess what: So does Haswell, but you won't be seeing Haswell in smartphones either. There's a price to all that performance and Nvidia is targeting the heavy-weight version of Tegra 4 at tablets because the power draw won't fly in a smaller smartphone platform, where the Tegra4i will be Nvidia's offering.
No plans for Tegra 4 in phones! (Score:5, Informative)
Tegra 4 will not be a phone part (at least not in any phoe that values battery life). Those A15 cores suck down batter life like vampires.
Like Tegra 3, Tegra 4 uses far too much power for mobile phones. The plan this time is to produce two products:
Tegra 4: 4 + 1 Coretex A15 + 72 shaders, several watts power consumption, aimed at tablets.
Tegra 4i: 4 + 1 tweaked Coretex A9 + 60 shaders + integrated LTE, much lower power. [tomshardware.com] Aimed at phones.
Nobody has committed to a Smartphone platform using the A15 precisely because the power consumption is too high. It may be tweaked over time, but right out the gate the power is just not there. This is why Apple went their own way with the A6.
